Django GET returning only 1 child instead of collection
I'm having an issue getting a list of objects with a GET request on this endpoint: /api/stock/{bar_id}/ It should return a list of stock for a specific Bar ID. In my schema, the Stock model contains the following properties: bar_id as a foreign key. ref_id as a foreign key. stock as integer. sold as integer. When I make the GET request I only end up getting the first stock, but I should be getting the full list of stocks. I understand that this end point is not RESTful, however it is an imposed constraint I have to make do with it and can't even pass the bar_id as parameter. What am I missing or doing wrong? Thanks for your responses! Object returned after the GET request: { "ref_id": { "ref": "first", "name": "first one", "description": "description" }, "bar_id": 1, "stock": 10, "sold": 0 } Expected returned object after the GET request: { [ { "ref_id": { "ref": "first", "name": "first one", "description": "description" }, "bar_id": 1, "stock": 10, "sold": 0 }, { "ref_id": { "ref": "second", "name": "second one", "description": "description" }, "bar_id": 1, "stock": 10, "sold": 0 } ] } Here is my BarSerializer: from rest_framework import serializers from … -

Invalid HTTP_HOST header: 'api.binance.com'
I keep on getting this error the moment I enabled error messaging in Django. I research about it. This binance thingy is about bitcoin and it is not related to what I'm doing. Is this an attack that's trying to check/access my Django Web app? Invalid HTTP_HOST header: 'api.binance.com'. You may need to add 'api.binance.com' to ALLOWED_HOSTS. Report at /api/v1/time Invalid HTTP_HOST header: 'api.binance.com'. You may need to add 'api.binance.com' to ALLOWED_HOSTS. Request Method: GET I check the api.binance.com. It is like an api and it says "ok" What's your thought about this? -
Django submit button refreshes page and does not remove values
I'm trying to get this submit button to work in my CreateView and have been debugging for quite some time now. Basically when I enter my values into the form and click submit, the page refreshes and all the values simply remain there. I do have a form_valid method where I print form.cleaned_data, but over at the terminal, it only shows a POST request but did not show form.cleaned_data. I'm really not sure where the problem is at all. I've tried setting action="." in my html but it simply says page not found. Any help is super appreciated!

Does using static variables in django views a good practise?
Assuming the get method is called at least one time before the post method.(This is not my actual code, if there's any silly mistake, don't consider it, my question is CAN I INSTANTIATE AND USE STATIC VARIABLE LIKE BELOW) class McqView(View): course=None all_questions=None start_time=None def get(self,request,someid): if not McqView.course: McqView.course = Course.objects.get(id=someid) if not McqView.all_questions: McqView.all_questions = Question.objects.filter(course=McqExamView.course) if not McqView.start_time: McqView.start_time = datetime.now() #using the static variables somewhere here def post(self,request): #using the same static variables somewhere here I thought of using the two as member variables but it is not possible. So I thought of using the two as static variables. will any problem arise while using this method? like 1.The static variables become None 2.The static variables gets instantiated more than once. If the second case happens, the start_time variable value will become wrong. Please tell me whether this is a wrong approach, if it is wrong tell me an alternative way of doing the same. -
How to make the ImageField optional in django rest framework API
I'm pretty tired finding solution to make the imagefield optional in django rest framework API. I tried each and every solution I found in stack overflow but nothing seems to be working fine. I know there are fewer posts related to same query but I didn't find the solution in that. Let me explain you what is my requirements. Here is my User model with some basic info fields including an Image field. models.py class User(models.Model): firstname = models.CharField(max_length=100, validators=[firstname_check]) lastname = models.CharField(max_length=100, blank=True, null=True, validators=[lastname_check]) username = models.CharField(max_length=100, unique=True, blank=True, null=True, validators=[username_check]) email = models.EmailField(max_length=100, unique=True) password = models.CharField(max_length=50, blank=True, null=True, validators=[password_check]) mobnum = models.CharField(max_length=50, blank=True, null=True, validators=[mobile_num_len]) timestamp = models.DateTimeField(auto_now=True) gender = models.CharField(max_length=50, blank=True, null=True) language = models.CharField(max_length=100, blank=True, null=True) profile_img = models.ImageField(upload_to ='uploads/', blank=True, null=True) is_active = models.BooleanField(default=False, blank=True, null=True) serializer.py from utils import Base64ImageField class UserMannualSerializer(serializers.ModelSerializer): profile_img = Base64ImageField( max_length=None, use_url=True, allow_empty_file=True, required=False ) class Meta: model = User fields = [ 'firstname', 'lastname', 'username', 'email', 'password', 'mobnum', 'gender', 'language', 'timestamp' 'profile_img' ] Here is the Base64ImageField() function which I've written inside the utils.py file.

Pagination for Django with big data
I tried to install pagination into Django app. I searched many codes online how to do that but most of them are for pagination with small amount of data. My app has close to 1 million PostgreSQL data. It seems like handling those big data with a typical pagination system does not work. you can see tons of pagination there.

allowedhosts=[] using Django and Apache2
I have a Django project and I am using Apache2. My settings.py file looks like this: DEBUG = False ALLOWED_HOSTS = ['localhost', '165.232.125.35', '.meesuis.org', 'www.meesuis.org'] When I type the 165.232.125.35 the site comes up fine.

Django projects fail on Ubuntu 20.04
I just upgraded Ubuntu from 18.04 to 20.04, and ALL my Django projects (tens of them) were not working. One of the problem related to psycopg2 when executing pip: For example, there is "psycopg2==2.7.3.1" in my "requirements.txt" file, and running "pip install -r requirements.txt" resulted in errors when building wheel for psycopg2. Change "psycopg2==2.7.3.1" to ""psycopg2-binary" solved the problem. So, is such change necessary for all projects running on Ubuntu 20.04? Other error examples from various projects when running server: RuntimeError: __class__ not set defining 'AbstractBaseUser' as <class 'django.contrib.auth.base_user.AbstractBaseUser'>. Was __classcell__ propagated to type.__new__?

Is there easier way to use bulk_create() with many query to instance create items
I don't have basic programming at all and just learned python and Django a few months ago, due to an urgent need I decided to create my own program to support my department and team After the program is running, I want to make it easier for the user and after I look around it is recommended to use bulk_create and ajax JavaScript, definitely not using JavaScript. After looking for ways to use bulk_create, I find it inefficient like: instance = get_object_or_404(Audit, id=766) item1 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=1) item2 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=2) item3 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=3) item4 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=4) item5 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=5) item6 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=6) item7 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=7) item8 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=8) item9 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=9) item10 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=10) item11 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=11) item12 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=12) audit_mie = [ AuditItem(audit=instance,item=item1,kategori=item1.kategori.kategori), AuditItem(audit=instance,item=item2,kategori=item2.kategori.kategori), AuditItem(audit=instance,item=item3,kategori=item3.kategori.kategori), AuditItem(audit=instance,item=item4,kategori=item4.kategori.kategori), AuditItem(audit=instance,item=item5,kategori=item5.kategori.kategori), AuditItem(audit=instance,item=item6,kategori=item6.kategori.kategori), AuditItem(audit=instance,item=item7,kategori=item7.kategori.kategori), AuditItem(audit=instance,item=item8,kategori=item8.kategori.kategori), AuditItem(audit=instance,item=item9,kategori=item9.kategori.kategori), AuditItem(audit=instance,item=item10,kategori=item10.kategori.kategori), AuditItem(audit=instance,item=item11,kategori=item11.kategori.kategori), AuditItem(audit=instance,item=item12,kategori=item12.kategori.kategori), ] AuditItem.objects.bulk_create(audit_mie) is there an easier way besides the method above? if not, then I stick with it, by creating objects in each item id which is approximately 130 (currently) and I will group it into 8 (currently) bulk_create() method. I am stuck here, if anyone can help this to make it easier, I am very, very Thank you -
Recommendations for possible feed algorithms?
I am currently tasked with creating an algorithm that delivers a continuous flow of posts to the end user via an endless scrolling mechanism. There are some obvious answers (e.i. display posts via date created and show them chronologically). However, this has some major drawbacks (e.i. depending on the timezone, some posts will get burried while others get all the attention arbitrarily). What are some alternative ways (with coding examples) to implement an algorithmic feed? Any resources/blog posts would be greatly appreciated. -
ModelAdmin - how to inline model to another model view using intermediate relation table using foreign key
I want to make able to edit (add or delete) film work persons (actors, writers, director). I have the following models: class FilmWork(models.Model): id = models.UUIDField(primary_key=True, db_column='id', default=uuid.uuid4) title = models.CharField(_('название'), max_length=255) class Meta: db_table = 'film_work' managed = False class Person(models.Model): id = models.UUIDField(primary_key=True, db_column='id', default=uuid.uuid4) full_name = models.TextField(_('полное имя'), max_length=255) class Meta: db_table = 'person' managed = False class FilmWorkPerson(models.Model): id = models.UUIDField(primary_key=True, db_column='id', default=uuid.uuid4) film_work = models.ForeignKey(FilmWork, models.DO_NOTHING, blank=True, null=True, related_name='film_work_person') person = models.ForeignKey(Person, models.DO_NOTHING, blank=True, null=True, related_name='person') role = models.CharField(_('роль'), max_length=50, choices=PersonRole.choices) class Meta: db_table = 'film_work_person' unique_together = (('film_work', 'person', 'role'),) managed = False Now I don't know how to show 'full_name' and 'role' fields on the FilmWorkAdmin(admin.ModelAdmin) - I found that Inline could help, but since I have intermediate table FilmWorkPerson which has ForeignKey field pointing to FilmWork, I can display 'role', but 'full_name' seems unaccessible in any way. Since it is not ManyToMany but ForeignKey I can not use 'through' I can't use fields lookup like 'person__full_name' since it is available in QuerySets filters only(?) I can not directly inline Person from FilmWorkAdmin since there are no direct connection between FilmWork and Person (did I miss some reverse lookup tool?) I don't believe … -

How can I serve a stand-alone static app through Django
We're using django for authentication, user management, site content etc, but we have a JS tool that needs to be behind django auth as well. The tool is an html page that pulls in a couple dozen static files through relative paths in the html page (src="./someJSfile.js"). The problem is I can't figure out how to serve the html file through django but keep the relative paths intact. I can create an apache alias to that directory so that the relative paths are intact, but then the html is served through apache and bypasses auth. I would like to be able to have the html file served through a django view so that auth works, and also keep the static files in the same directory. Is there some apache magic where I can have the html served through django but have the static served through apache using an alias, while keeping the html and static in the same directory? Thanks in advance -

Persistent "[Errno 61] Connection refused" error in Django
in my Django project, I am running these commands on shell: >>> from django.core.mail import send_mail >>> send_mail('Django mail', 'This e-mail was sent with Django.', 'my@email.com' ['out@email.com'], fail_silently=False) I keep receiving this error: ConnectionRefusedError: [Errno 61] Connection refused This is my current settings.py: import os import smtpd from pathlib import Path ... EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = 587 EMAIL_HOST_USER = 'my@email.com' EMAIL_HOST_PASSWORD = 'password' EMAIL_USE_TLS = True The strange thing is that I still receive the same error even when I add this code to write emails to console instead: EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' I have tried all the tips I could find including, activating less secure apps in Gmail, acquiring a Gmail app password, and even tried using Mailjet with django-anymail. Nothing made a difference, still received the same error message when I run that command in shell. I'm running Python 3.6 and Django 3.1.2 -
Deploy Web Application Nuxtjs/Django/PostgreSQL
Right now I'm developing a website base on Nuxt as the Frontend and Django as the backend with a PostgreSQL database, I'm a little new to this field but I'm not sure how exactly to deploy and host my app, I've been looking at AWS Services to do it, like using Lightsail or just deploy everything on an ES2 instance to save money instead of deploying each element on a different server, the problem with the last option is that it wont be able to scale, in case in the future the visits to the site increase. I really appreciate some recommendation or orientation about how I could do it this easy, cheap and scalable. -
How to pass multi optional URL parameters in django?
How to pass multi optional URL parameters? For example I want pass 2 params: my_color and my_year, but they are optional, so may be none of them will be passed, may be both, or may be only one. Currently in urls.py I have : urlpatterns = [ re_path(r'^products/(?P<my_color>.*)/(?P<my_year>.*)$', some_view), ] This obviously is not correct and works only if both of them are passed. What would be correct solution? P.S. I found answers when only one optional parameter needs to be pass, but not figured out how to do same for few parameters. Also it seems "multiple-routes option" is not solution in this case ?
