Trying to test multiple test files with multiple test classes but PyTest doesn't recognize other files
I've been scouring all over the internet in order to find solution for this problem. I've been trying to make sure that PyTest recognizes multiple test files to account for the multiple test files and the classes inside them in order to build a full test suite. Here's the config file: [pytest] asyncio_mode=auto asyncio_default_fixture_loop_scope="class" DJANGO_SETTINGS_MODULE = personal_blog.settings testpaths = tests Here's the test class that it recognizes: test_members.py import pytest import factory from django.contrib.auth import get_user_model from factories import MemberFactory from faker import Faker from django.urls import reverse from django.contrib.auth.models import Permission fake = Faker() # Create your tests here. User = get_user_model() # Basic Tests class TestMembers: #Confirms that a user has been created @pytest.mark.django_db def test_if_user_exists(db): user = MemberFactory() assert user.username is not None assert user.email is not None # Checks if the password fails @pytest.mark.django_db def test_set_check_password_fail(db): # basic_user.set_password("password") user = MemberFactory() assert user.password != 'Wrong' # Checks if the password fails @pytest.mark.django_db def test_set_check_password_success(db): user = MemberFactory() assert user.password == 'password' # Checks if the user is not a contributor by default. @pytest.mark.django_db def test_is_not_contributor_by_default(db): user = MemberFactory() assert user.is_contributor is False # Checks if the User is a contributor @pytest.mark.django_db def test_is_contributor(db): user = MemberFactory(is_contributor … -
Django Static Image Not Displaying When Using Variable for Image Path
I'm trying to load and display a static image in a Django template. I have a dictionary named post that contains an image value, for example, "mountain.jpg". I checked, and the dictionary has the correct data. However, when I try to set the image path dynamically using post.image, the image is not displayed. If I hardcode the URL, the image shows up correctly. Here is my image tag in the template // not working <img src="{% static "blog/images/"|add:post.image %}" alt="Mountain" /> // working <img src="{% static "blog/images/mountain.jpg" %}" alt="Mountain" /> -
Why does VScode keep popping the "SyntaxError" message, even before i am done typing?
syntax error massage, this is the error message suggestions that keeps popping up and interrupting my code flow, most times i have to comment my lines of code, and that is not ideal, so removing it would be the best. i tried going to settings to look for it , but could not find anything. I even had to go to the Json file, but to no avail, i really need help soonest -
Can I reuse output_field instance in Django ORM or I should always create a duplicate?
I have a Django codebase that does a lot of Case/When/ExpressionWrapper/Coalesce/Cast ORM functions and some of them sometimes need a field as an argument - output_field. from django.db.models import FloatField, F some_param1=Sum(F('one_value')*F('second_value'), output_field=FloatField()) some_param2=Sum(F('one_value')*F('second_value'), output_field=FloatField()) some_param3=Sum(F('one_value')*F('second_value'), output_field=FloatField()) some_param4=Sum(F('one_value')*F('second_value'), output_field=FloatField()) some_param5=Sum(F('one_value')*F('second_value'), output_field=FloatField()) Sometimes I find myself wondering why am I always creating the same instance of any Field subclass over and over again. Is there any difference if I just pass one instance and share it between expressions? F.E from django.db.models import FloatField, F float_field = FloatField() some_param1=Sum(F('one_value')*F('second_value'), output_field=float_field) some_param2=Sum(F('one_value')*F('second_value'), output_field=float_field) some_param3=Sum(F('one_value')*F('second_value'), output_field=float_field) some_param4=Sum(F('one_value')*F('second_value'), output_field=float_field) some_param5=Sum(F('one_value')*F('second_value'), output_field=float_field) I coulnd't find it in a documentation and the source code is not documented well regarding this parameter. P.S. The example is fake, just imagine a big annotate function that does a lot of processing using Case/When/ExpressionWrapper/Coalesce/Cast and has a lot of duplicated Field instances as output_field. -
Discrepancy in Record Count Between Django ORM and Raw SQL Query
I'm encountering an issue where the count of records returned by a Django ORM query does not match the count returned by a raw SQL query. Here is the relevant part of my Django view: start_date = datetime(2024, 10, 19, 0, 0, 0) end_date = datetime(2024, 10, 19, 23, 59, 59) dbug = Reservations.objects.all().filter(updated_at__range=(start_date, end_date)) print(dbug.count()) Above returns 6529 The Django settings.py contains: TIME_ZONE = 'Asia/Tehran' USE_TZ = False I have tried SQL query same bellow: SELECT COUNT(*) FROM "consultant_reservations" WHERE updated_at BETWEEN '2024-10-19 00:00:00' AND '2024-10-19 23:59:59'; count ------- 6540 (1 row) Here is discrepancy within SQL query result (which is 6540) I have tried in psql terminal and Django ORM result (which is 6529) Please let me presenting an example: Trying SQL query same as: SELECT * FROM "consultant_reservations" WHERE updated_at BETWEEN '2024-10-19 00:00:00' AND '2024-10-19 23:59:59' LIMIT 4; Result: id | idd | voip_number | client_id | client_mobile | reserve_duration | status | reserve_timestamp | created_at | updated_at | consultant_id_id | mobile_id | created_by | updated_by -------+---------+-------------+-----------+---------------+------------------+----------+------------------------+------------------------+------------------------+------------------+-----------+------------+------------ 76407 | 2011050 | 2217 | 1101151 | 09355648120 | 3600 | reserved | 2024-10-19 19:30:00+00 | 2024-10-14 08:40:03+00 | 2024-10-19 20:28:01+00 | 5052 | 2395781 | 3445 | 0 … -
Are consecutive django model save calls safe?
I'm having trouble with a field that seems to sometimes not update. Just want to know if the following is unsafe on a Django model instance. obj.field1 = True obj.save() obj.field2 = True obj.save() Since I'm not calling obj.update_from_db() is there any risk the second save resets/overrides field1 ? There are no post_save hooks involved, the surrounding code is synchronous and the DB backend is PostgreSQL. Also, is save() synchronous (in the sense that the DB update will happen before the function returns)? -
WebSocket Connection Issue with Django Channels in Gunicorn

How to run a Python Django project that is deployed on a local machine?
I attempted to run a deployed Django project on my local machine by setting up a virtual environment and installing all required dependencies. I also modified the production.py settings, specifically the ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS, to include local addresses like http://127.0.0.1:8000. However, despite these changes, the project only displayed a public IP and did not allow me to access it locally. I would like guidance on additional adjustments needed in the production.py or elsewhere to successfully run the project on my local machine. -

Django TypeError: Cannot filter against a non-conditional expression while filtering by foreign key
I've looked through multiple similar questions, but couldn't get the logic, and my manipulations were unsuccessful. I have a forum app, its structure is "forum->subforum->topic->comments", corresponding models for subforums, topics and comments. I have to implement a filter on each subforum page (where the list of corresponding topics is displayed), by which I can configure the search of/among the topics by several conditions. Particularly I have to implement a custom filter, and my idea was to create a filter for empty topics, that is, for topics only with initial comments and without responses. Through a desperate struggle I've finally understood how to implement reversed foreign key connection in querysets, but now I can't use a queryset expression as a filter, as it returns TypeError: Cannot filter against a non-conditional expression. Here are the specifics: filters.py: import django_filters from django.db.models import Count from forum.models import Topic class TopicFilter(django_filters.FilterSet): date_span = django_filters.DateRangeFilter(field_name='created', label='Период создания') comments = django_filters.CharFilter(field_name='comment__content', lookup_expr='icontains', label='Комментарии') subject = django_filters.CharFilter(lookup_expr='icontains', label='Тема обсуждения') creator = django_filters.CharFilter(field_name='creator__username', lookup_expr='icontains', label='Создатель темы') is_empty = django_filters.BooleanFilter(method='filter_empty', label='Темы без комментариев') class Meta: model = Topic fields = ['subject', 'creator', 'date_span', 'comments', 'is_empty'] def filter_empty(self, queryset, value): comment_count_gte_1 = Topic.objects.annotate(comment_count=Count('comments')).filter(comment_count__gte=1) comment_count_lt_1 = Topic.objects.annotate(comment_count=Count('comments')).filter(comment_count__lt=1) if value is True: … -
Optimizing Django QuerySet with Nested Aggregations
I’m working on optimizing a complex Django query where I need to perform nested aggregations and conditional annotations across multiple related models. I want to fetch the top 5 most active users based on their interactions with posts, while also calculating different types of engagement metrics (like views, comments, and likes). My models: class User(models.Model): name = models.CharField(max_length=100) class Post(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=255) created_at = models.DateTimeField() class Engagement(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) type = models.CharField(max_length=50) # 'view', 'like', 'comment' created_at = models.DateTimeField() Here is what my code looks like: from django.db.models import Count, Q some_date = ... top_users = ( User.objects.annotate( view_count=Count('engagement__id', filter=Q(engagement__type='view', engagement__created_at__gte=some_date)), like_count=Count('engagement__id', filter=Q(engagement__type='like', engagement__created_at__gte=some_date)), comment_count=Count('engagement__id', filter=Q(engagement__type='comment', engagement__created_at__gte=some_date)), total_engagements=Count('engagement__id', filter=Q(engagement__created_at__gte=some_date)) ) .order_by('-total_engagements')[:5] ) It works, however the query performance is not ideal. With large datasets, this approach leads to slow query execution times and I wonder whether using multiple Count annotations with filter conditions is efficient. Is there a more optimized way to write this query, or any best practices I should consider for improving performance, especially when dealing with large amounts of data? Any insights or suggestions would be really helpful! -
Django dynamically adding integer fields to forms
Hi I have a very simple application that I am making in order to learn Django. I have a SQLite table that has two columns, the first is the 'id' generated by Django, the second is a charfield containing the name of a product_name. The way I am trying to get the program to work is as follows: Get value list of values in the table. This query_set gets assigned to bases Loop through the each tuple in the bases list and use these values to create form fields. So the product_name will be the Label and the id will be the id of the field. I will later use Jquery on these fields to get the values. I have the following code: from django import forms from django.db import models from django.core.exceptions import ValidationError from .models import Department, Test_list, Products, Current_tests class Batch(forms.Form): bases = Products.objects.all().values_list('product_name','id') for i in bases: for j in [0,1]: bn = i[0] bnid = i[1] name = forms.IntegerField(label=f"{bn}",widget=forms.NumberInput(attrs={"id":bnid})) The code actually works but instead of getting a number of text inputs equal to the rows in my database, it only shows the last row. I believe this is because while in the loop, I … -
Django + jQuery: No Image Provided Error with 400 31 Response When Uploading Image via AJAX
I'm working on a Django project where I'm uploading an image to be processed by a machine learning model. The frontend uses jQuery to send the image via an AJAX request. However, the server keeps returning the error: {"error": "No image provided."} and Accuracy: NaN%. Additionally, I receive the response 400 31 in the browser console.

Rendering MultiValueField including help_text and label for each subfield
I am using a JSONField to represent a config that is used in multiple forms. Instead of the default Textarea widget, I want to render multiple fields each with their own label and help_text. I am able to achieve this by implementing a Form just for the config but it seems it should also be possible (and cleaner) to represent the config as a MultiValueField. Unfortunately I cannot for the life of me figure out how to render the label and the help_text when following this approach as that information seems no longer available when the widget is rendered. What am I missing? class ConfigWidget(forms.MultiWidget): template_name = 'config_widget.html' def __init__(self, attrs=None): widgets = [ forms.TextInput(attrs=attrs), forms.TextInput(attrs=attrs), ] super().__init__(widgets, attrs) def decompress(self, value): if isinstance(value, dict): return [value['foo'], value['bar']] return [None, None] class ConfigField(forms.MultiValueField): widget = ConfigWidget def __init__(self, *args, **kwargs): fields = ( forms.CharField(label='Foo', help_text='Foo help.'), forms.CharField(label='Bar', help_text='Bar help.'), ) super().__init__(fields=fields, *args, **kwargs) def compress(self, data_list): if data_list: return { 'foo': data_list[0], 'bar': data_list[1], } -
Django test client redirects logged users to login page
I know this questions has already been asked, but none of the answers works for me. Whenever I try to use the client login in Django tests, it basically gets ignored and I get a redirect to the login page. After a few test I noticed that it logs me in correctly, but kicks me out when I use it.

Save number of total search query count on models in Django

Python requests Session not passing cookies?
I have followed the documentation as far as I can tell, but it seems that the requests library Session object is not retaining cookies. Here is my simple code: with requests.Session() as s: url = '%s://'%http+serverStr+'/login/' s.get(url) payload = {'username': 'sfprod', 'password': <password>, 'csrfmiddlewaretoken': s.cookies['csrftoken'], 'next': '/'} login_resp = s.post(url, data=payload, headers=(dict(Referer=url))) This is connecting to a Django server. When I run the first s.get() call I see these cookies returned: <RequestsCookieJar[Cookie(version=0, name='csrftoken', value='Iw2k4RF5QIy6oNOA71681oq4kGVBxjzTmQCULicbWdr5ZfH1Kunrn30DNupQtFhF', port=None, port_specified=False, domain='gancho.local', domain_specified=False, domain_initial_dot=False, path='/', path_specified=True, secure=True, expires=1761043315, discard=False, comment=None, comment_url=None, rest={'SameSite': 'Lax'}, rfc2109=False)]> However when the second call happens, no cookies are passed to the server. The COOKIES member of the request object received is empty and the server returns 403 Forbidden. I stepped through the csrftoken code in the debugger and it is rejecting the request because the cookie is not present (to be precise, because there is no CSRF_COOKIE value in the META member of the request, but I assume this is because the cookie is not present). I can log in with a browser, and in this case I see the cookie in the request, so I think it is not a setup problem with the server. Is there something I … -
Is it safe and ok to divide mp3 file like that?
I have an mp3 file and want to divide it into several files ("chunks"). I came up with this code (I stole the idea from django): from pathlib import Path class FileWrapper: def __init__(self, file) -> None: self.file = file def chunks(self, chunk_size): chunk_size = chunk_size try: self.file.seek(0) except (AttributeError, Exception): pass while True: data = self.file.read(chunk_size) if not data: break yield data with open("./test2.mp3", "rb+") as src: wrapper_file = FileWrapper(src) for chunk_ind, chunk in enumerate(wrapper_file.chunks(chunk_size=100 * 1024)): out_file_path = Path("./", f"test2_{chunk_ind}.mp3") with open(out_file_path, "wb+") as destination: destination.write(chunk) And, you know, it's working okay, but I'm scary and in doubt, that this approach can sometimes work, but sometimes it maybe can "brake" resulted "chunks". So, is this way - okay? Or I need to dive deeper into how mp3 files made? -

mysqlclient not found even after installed in Django on MacOS
I use pyenv to create a virtual-env, and install mysqlclient in it successfully. But when I python manage.py runserver, it shows 'Did you install mysqlclient?'. How to resoleve it? I try it both in terminal and PyCharm, all did not work. I also looked up a lot of technical forums and basically said that the virtual environment mismatch is the reason, and no one is in the same situation as me. -
How do I avoid a SuspiciousFileOperation when uploading a Django photo?
from django_resized import ResizedImageField class UserProfilePhoto(Model): photo = ResizedImageField(size=[128, 128], upload_to=MEDIA_ROOT) photo_hash = BigIntegerField( blank=True, null=True, help_text=_("an integer representation of the hexdigest hash of the photo"), ) def __str__(self): return f"{self.photo.name} ({self.photo_hash})" I used to have a save() operation in the model, which would do the resizing but now I'm using Django-resized because after all that figuring out how to resize the photo and generate a hash value it turns out there is a module to do it already. I'm adding a picture to the userprofilephoto in the admin. SuspiciousFileOperation at /admin/userprofile/userprofilephoto/add/ Detected path traversal attempt in '/app/mine/media/mendlebrot-lawn.jpeg' How do you turn off the error or the validation? To answer some questions in advance: No. I'm not going to go back to ImageField() It gave me the same problem with lots more code. -
how to fix my register view that generates a token and assigns it to a cookie? django error
Hello I am having trouble building a register view for my django homework assignment. I'm a beginner and trying to work on my register functionality and the views file is where I am having trouble. It's supposed to add a new user to user table in the database, and create a session key string and assign it to the cookie so the user can stay signed in. Whenever I submit a new user it redirects and gives me this error ValueError: Field 'id' expected a number but got 'pjtjtksydunpdysgxcxtmpazfyawvqzg' (my generated string) Here's my register view def register(request: HttpRequest): if request.method == 'POST': params = request.POST user = User( name = params.get("name"), email = params.get("email"), password_hash = params.get("password") ) hasher = hashlib.sha256() hasher.update(bytes(user.password_hash, "UTF-8")) user.password_hash = hasher.hexdigest() user.save() token = "" letters = string.ascii_lowercase for _ in range(32): token = "".join(random.choice(letters) for _ in range(32)) session_token = Session.objects.create(user=user, token=token) response = redirect("/") response.set_cookie('token', token) return response return render(request, "destination/register.html") here are my models in case if needed class User(models.Model): id = models.BigAutoField(primary_key=True) name = models.TextField() email = models.EmailField(unique=True) password_hash = models.TextField() class Session(models.Model): id = models.BigAutoField(primary_key=True) user = models.OneToOneField(User, on_delete=models.CASCADE) token = models.TextField() register.html <!DOCTYPE html> <html lang="en"> <head> <meta … -
Excel File Corrupted When Downloaded from Django Backend via Axios in Vue.js
I'm trying to download an Excel file from my Django backend to the frontend using Axios and FileSaver.js (also tried without this). The file is generated successfully on the backend, but when I download it through the frontend, the file becomes corrupted and cannot be opened by Excel. I am using pandas to create the Excel file in-memory and then return it as a response. Backend code - buffer = BytesIO() with pd.ExcelWriter(buffer, engine='xlsxwriter') as writer: for item in data_list: attributes = item['attributes'] attributes['ID'] = item['id'] df = pd.DataFrame([attributes]) sheet_name = f"Sheet_{item['id']}" df.to_excel(writer, sheet_name=sheet_name, index=False) buffer.seek(0) response = HttpResponse(buffer, content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet') response['Content-Disposition'] = 'attachment; filename="data_export.xlsx"' return response Frontend code - async function downloadFile() { try { const response = await axios.get('/api/export-excel', { responseType: 'blob', }); saveAs(new Blob([response.data]), 'data_export.xlsx'); } catch (error) { console.error('Error downloading file:', error); } } I know there are similar questions already asked and I have already tried those things (using arraybuffer, type - ms-excel, also tried using openpyxl) but none seems to work. What could be causing the file corruption during download via the frontend? How can I ensure that the file downloads correctly and opens in Excel without corruption? Any advice or suggestions would be greatly …
