Having posts separated by more than one category on the Home Page|Django
I want to divide the home page into categories. And categories should contain post titles. I can redirect categories in another url, but I can't show it on the home page. i have 2 models: blog and category models.py class Category(models.Model): parent = models.ForeignKey('self', on_delete=models.CASCADE, blank=True, null=True, related_name='children'); title = models.CharField(max_length=120, verbose_name='kategori') slug = models.SlugField(unique=True, editable=False) class Blog(models.Model): user = models.ForeignKey('auth.User', verbose_name='yazar', on_delete=models.CASCADE, related_name='blogs') title = models.CharField(max_length=120, verbose_name='başlık') # content = models.TextField(verbose_name = 'metin') content = RichTextField(verbose_name='metin') category = models.ForeignKey(Category, on_delete=models.CASCADE, default='') image = models.ImageField(null=True, blank=True, verbose_name='foto') publishing_date = models.DateTimeField(verbose_name='tarih') onem = models.BooleanField(default='True') slug = models.SlugField(unique=True, editable=False) view.py from django.shortcuts import render # Create your views here. from blog.models import Blog,Category def home_view(request): categorys = Category.objects.all() blogs = Blog.objects.all() r =Blog.objects.filter(category__title=Blog.category) return render(request,'index.html', {'blogs' : blogs, 'categorys' : categorys, 'r':r,}) def about_view(request): return render(request, 'about.html' , {}) def category_detail(request, cats): category_posts = Blog.objects.filter(category__title=cats) return render(request, 'category.html' , {'cats':cats, 'category_posts':category_posts, }) How should the index.html structure be? -
django.db.utils.IntegrityError: NOT NULL constraint failed: unesco_site.category_id
I am trying to populate database from data in the csv file using a python script. I did some research but couldn't find a relevant example rather I found python packages that would load csv. And there some articles guiding on how to upload csv file which isn't what I wanted. Following is a glimpse of load.csv file.

Deploying Django with Nginx, Gunicorn and Supervisor
I'm trying to deploy my Django app with Nginx and Gunicorn by following this tutorial, but I modified some steps so I can use Conda instead of ViritualEnv. The setup looks like this: Nginx replies with my Vue app Requests from Vue are made to api.mydomain.com Nginx listens to api.mydomain.com and directs requests to Gunicorn's unix socket Things I've checked: I can see the Vue requests in Nginx's access.log. I can also see those requests with journalctl -f -u gunicorn and in my supervisor.log. When my Django app starts, it's creates a log file, so I can see that Gunicorn starts it. But Django is not responding to requests from the unix socket. I can see a response from Django when I ssh in and run the following command: curl --no-buffer -XGET --unix-socket /var/www/mydomain/run/gunicorn.sock http://localhost/about. This command only gives a response when http://localhost is included. My Nginx, Supervisor and Gunicorn configurations all use the full path to gunicorn.sock. Should I see Django running on port 8000 or anything if I do something like nmap localhost? I saw another post mention that Nginx should point to port 8000 and that gunicorn should be run with either: gunicorn --bind 0.0.0.0:8000 <djangoapp>.wsgi --daemon … -
How to compare 2 fields from 2 different models in Django?
I want to compare 2 fields from 2 different models and here is the idea behind it. Teacher can create Class which has ManytoManyField with Student model. When the Class model is created it will generates a random_code and Students will have to enter that code via EnterCode model to join the Class model. models.py class Class(models.Model): teacher = models.ForeignKey(CustomUser, on_delete=models.CASCADE) student = models.ManyToManyField(Student) random_code = models.CharField(max_length=250, default=uuid.uuid4().hex[:6]) subject = models.CharField(max_length=150) class EnterCode(models.Model): student = models.ForeignKey(CustomUser, on_delete=models.CASCADE) code = models.CharField(max_length=50) class Teacher(models.Model): user = models.OneToOneField(CustomUser, on_delete=models.CASCADE, primary_key=True) class Student(models.Model): user = models.OneToOneField(CustomUser, on_delete=models.CASCADE, primary_key=True) So the Class object 1 will generates a code and when student enters that code it will adds that student to the student field (ManyToManyField) in Class Model. How can I compare code with random_code and add Student to ManytoManyField? -
Patch a class method used in a view
I'm trying to test my view given certain responses from AWS. To do this I want to patch a class I wrote to return certain things while running tests. @patch.object(CognitoInterface, "get_user_tokens", return_value=mocked_get_user_tokens_return) class TestLogin(TestCase): def test_login(self, mocked_get_user_tokens): print(CognitoInterface().get_user_tokens("blah", "blah")) # Works, it prints the patched return value login_data = {"email": "whatever@example.com", "password": "password"} response = self.client.post(reverse("my_app:login"), data=login_data) Inside the view from "my_app:login", I call... CognitoInterface().get_user_tokens(email, password) But this time, it uses the real method. I want it to use the patched return here as well. It seems my patch only applies inside the test file. How can I make my patch apply to all code during the test? -

I am working on a web app using Django, running on Nginx, and I am getting 111 connection refused, and I cant work out why
I have previously configured an app in the exact same way but when I updated Ubuntu, I broke my python install. I fixed python, and tried to set up another app in the exact same way, using the same tutorials, but I am getting a 111 error when I try to connect. I can connect if I run the app using gunicorn (which I only tried because it wasn't working using nginx), but I want to find the problem and fix it.

Django CharField as primary key still allow Null value to be save
Currently i have the following model that i would like to set CharField as primary key( my database is Mysql) class Customer(models.Model): class Meta: db_table = "customers" verbose_name = _('Customer') verbose_name_plural = _('Customers') customer_id = models.CharField(_('Customer ID'),max_length=255, primary_key=True) name = models.CharField(_('Name'), max_length=255) created_at = models.DateTimeField(auto_now_add=True) In the document it stated that : primary_key=True implies null=False and unique=True. Only one primary key is allowed on an object. In Mysql the primary key has the following structure: customer_id, type=varchar(255), collation=latin1_swedish_ci, Attributes=blank Null=No, Default=None,Comments=blank, Extra=blank but when i try to use the save() method with null value for primary key: Customer.objects.create(customer_id=None, name="abc") It still save Null value in the primary key without returning any error or validation, why is that? -

Django Object is Not Serializable CommandError using Dumpdata with Natural Keys
I am trying to use 'natural keys' for serialization (docs) in a "manage.py dumpdata" command: python manage.py dumpdata --natural-primary --natural-foreign --indent 4 --format json --verbosity 1 > tests\test_fixtures\test_db2.json and I am getting the following error when I use --natural-foreign on other apps that use the Project or Task model (which they all must by design): CommandError: Unable to serialize database: Object of type Project is not JSON serializable Exception ignored in: <generator object cursor_iter at 0x000001EF62481B48> Traceback (most recent call last): File "C:\Users\Andrew\anaconda3\envs\Acejet_development\lib\site-packages\django\db\models\sql\compiler.py", line 1586, in cursor_iter cursor.close() sqlite3.ProgrammingError: Cannot operate on a closed database. If I just dumpdata from this, the 'projects' app, it works, but other apps are built with entities related to Project or Task and there the --natural-foreign option fails. The problem occurs when a model (say Question) calls for a natural_key from Task, which includes a for a natural_key from Project. If I use the Pycharm Python Console to access querysets of Projects or Tasks ('q' here), this works: serializers.serialize('json', q, indent=2, use_natural_foreign_keys=True, use_natural_primary_keys=True) But if 'w' is a list of Question objects from another app that have a Task foreign key I get this error: Traceback (most recent call last): File "<input>", line 1, … -
How to check a radio button based on user input in a Django Template?
I'd like to check a specific radio button if one or two of the values of my two input fields exceeds a certain number. I am currently using Django Form to render both the textboxes and the radio buttons: Like this: The Radio Button: 'gap_result': HorizontalRadioSelect( choices=NG_gap, attrs={ 'default': 'OK', 'class': 'radio colorC', 'style': ' margin-top: 15px; margin-left: 25px;', 'name': 'radio_Gap', 'id ': 'radio_Gap_Result', }), The two textboxes: 'gap_X': forms.TextInput( attrs={ 'class': 'form-control cent ', 'placeholder': 'X', 'type': 'text', 'id': 'gap_X', # 'readonly': 'false', }), 'gap_Y': forms.TextInput( attrs={ 'class': 'form-control cent ', 'placeholder': 'Y', 'type': 'text', 'id': 'gap_Y', }), What I need is to change the radio button to be OK if neither of the values exceeds 8 and then NG if it does. Here's a visual representation: Here's what I have in my template using the django forms: <div class="row"> <div class = "col-3"> <div class="form-text"> {{form.gap_X}} </div> </div> <div class = "col-3"> <div class="form-text"> {{form.gap_Y}} </div> </div> {{form.gap_result}} </div> -

I am studying DRF, and I have a question about specifying ManyToManyField in serializers
While creating a group, I want to add the User received in the request to the members column, the ManyToManyField of the group model.

Mocking Django inclusion tag in pytest
I have an inclusion tag: from django import template from accounts.models import UserTracking register = template.Library() @register.simple_tag(takes_context=True) def has_shipped(context): return UserTracking.objects.filter(shipping=True, user=context['request'].user).exists() and I am testing a function, awarded, that is calling a template that contains that tag. from unittest.mock import patch from myproject.views import awarded @patch('myproject.templatetags.something.has_shipped') def test_awarded(mymock, rf): mymock.return_value = '' # this is not having any effect result = awarded(rf) assert result and the code under test: def awarded(request): return render(request, 'awarded_form.html', {'revisions' : revisions}) Pytest is yelling at me because it says I'm using the database, which I am (but don't want to), so I want to mock the function containing the database call, has_shipped. How do I do that? When I try to mock the function directly from where it is declared, it doesn't work, because it's apparently not the right scope, so how do I do this? And is this one of those situations where it's just easier to throw @mark_db on it? -
Error displaying list of registered user profiles in Django app using class based views

Here is the code I tried, one of the dozens approaches: {% product_events event_type='add to observation' for_last_days=1 count=5 unique=1 order=-1 in_stock='true' as observe_list %} {% product_events event_type='purchase' for_last_days=1 count=5 unique=1 order=-1 in_stock='true' as purchase_list %} {% for event in observe_list %} {% if event.name not in purchase_list %} {{ event.name }} {% endif %} {% endfor %}
