Django ModelForm Hidden Field to 'True' in only a certain situation?
I've got the following Django Form; it has a field called 'finished', that is hidden. I set the default to False because there is only one situation where I want it set to True. The problem is that it still marks it as "False" and I can't figure out how to change it in that one situation. In my views.py I have this: context["test_form"] = TestForm( instance=self.object, hide_status=True, is_finished=True ) the form looks like this: class TestForm(ModelForm): finished = forms.BooleanField( widget=forms.HiddenInput(), initial=False, required=False ) status = forms.Select(attrs={"class": "form-control"}) def __init__(self, *args, **kwargs): hide_status = kwargs.pop("hide_status", None) is_finished = kwargs.pop("is_finished", None) super().__init__(*args, **kwargs) self.fields["status"].queryset = Status.objects.filter(active=True) self.fields["status"].widget.attrs["class"] = "form-control" if hide_status: self.fields["status"].widget = HiddenInput() if is_finished: self.fields["finished"].initial = True class Meta: model = Test fields = ["finished", "status"] The HTML is super simple: <form method="post" action="{% url 'my_app:test-update' %}"> {% csrf_token %} {{ test_form.as_p }} <button type="submit" class="btn btn-primary">Finish</button> </form> The rendered HTML looks like this: <input type="hidden" name="finished" value="False" id="id_finished"> What is the best way to get that set to True in this case? -
How to properly check authentication with Vue.js (Vue router) and Django
I am trying to check if a user is authenticated on protected routes in vue-router. I have Django rest framework that sets sessionid on login. I have seen people using vuex or local storage to store session information. But, If the token was forcibly expired on the server-side a user will be allowed to navigate since localStorage still says IsAuthenticated=true. In this case, is it the best choice to make a request to the Django backend such as fetch("url/auth/authenticated")? -
Djoser is ignoring my Authenitcation Token
I set up djoser and DRF's TokenAuthentication. It works perfectly for registering users, and i get a valid token returned. When I try to access /users/me or /token/logout with header: Authorization: Token {token} (and the token itself in the body for good measure) I get the response Error 403: "Authentication credentials not provided." I've tried making the request through axios and postman. I made other accounts and tried their keys but I get the same result. I've looked on the djoser docs but there is no help there, nor anywhere else, because it seems no one else has this issue. -
Can you connect to a Django backend via a python separate file? if both are running locally
For example, when I would create a ruby and react app. I could run the ruby app on local.host:3000 and the react app on local.host:4000. With some configuration, I could fetch information from my ruby backend and send information from by react frontend. Currently, I am working on building a bot on discord, with a django frontend/backend. I need to run the python bot at the same time as the Django website. I run the bot via "python main.py". I run the django project via "python3 manage.py runserver" runs on http://127.0.0.1:8000/. They both work fine at the same time, but I want the bot to be able to send information to the django project. I don't believe its like ruby. I cant just fetch to http://127.0.0.1:8000/ bc that is not the backend. That is the frontend of the site(?). So, is there anyway for me to get the URL of the django backend, so I can send information to it via my python bot. I cannot seem to find an article on this, any help would be greatly appreciated. Thanks! -

Getting error code 247 while deploying django app
I am trying to deploy my Django application to Digital ocean droplets, using the less expensive one, that gives me 512 mb of ram, 1 CPU and 10 gigs of SSD. Then, after I set up everything properly, I run docker-compose up --build to see if everything is fine. It launches all. In my docker compose, I use a postgres instance, a redis one and a celery one, and the django application I wrote. If that matters, here is the docker-compose file version: "3.9" services: db: container_name: my_table_postgres image: postgres ports: - 5432/tcp volumes: - my_table_postgres_db:/var/lib/postgresql/data environment: - POSTGRES_DB=my_table_postgres - POSTGRES_USER=dev - POSTGRES_PASSWORD=blablabla redis: container_name: redis image: redis ports: - 6739:6739/tcp environment: - REDIS_HOST=redis-oauth-user-service volumes: - redis_data:/var/lib/redis/data/ my_table: container_name: my_table build: . command: python manage.py runserver 0.0.0.0:5000 volumes: - .:/api ports: - "5000:5000" depends_on: - db - redis celery: image: celery container_name: celery restart: unless-stopped build: context: . dockerfile: Dockerfile command: ['python', '-m', 'celery', '-A', 'mytable' ,'worker', '-l', 'INFO'] volumes: - .:/api depends_on: - redis - my_table links: - redis volumes: my_table_postgres_db: redis_data: Then, all starts up quite slowly, but after I try to make a request from something like postman, in the terminal of docker compose, the main process … -
How to display a custom form with multiple widgets for a field in Django admin?
The Django docs say you can add a form to the admin UI: class ArticleAdmin(admin.ModelAdmin): form = MyArticleAdminForm I want a custom editing UI for a special field in my model, where I display multiple widgets. (It's not exactly the same, but an analogy might be a calendar widget where values on the calendar are editable.) Perhaps I could break the multiple values into multiple database objects and use an InlineAdmin, but I have app-specific reasons to not do that. I thought I'd use a Form object with some custom fields, but Django says it must be a ModelForm: <class 'myapp.admin.MyAdmin'>: (admin.E016) The value of 'form' must inherit from 'BaseModelForm'. Is it possible to display multiple widgets (basically a very custom form) for a single model value in Django admin? -
Django not logging in properly when custom backend and models are used
I'm trying to implement a custom authentication backend in Django but its behaving in a very strange way. The custom backend authenticate against a different model from the usual Django User model an upon successfully verifying the provided credentials the backend get or create our usual Django User instance which it returns. Login nevertheless doesn't work. From the documentation I learnt that I just needed to inherit the django.contrib.auth.backends.BaseBackend and override the authenticate() method which I did. As I've mentioned the custom authenticate() method basically verifies a set of credentials (username and password) against ones stored in the database (custom model, not django.contrib.auth.models.User) which if matched it would get or create an instance of django.contrib.auth.models.User via a proxy model which I named Profile; basically the Profile model has a reference of both django.contrib.auth.models.User and my custom model. When logging in though I keep redirected to the login page (It's like Django logs me in but doesn't set something somewhere such that when I try accessing a protected resource I'm redirected back to login). Also when I login which a django.contrib.auth.models.User object it works just fine and I can access the protected pages. Following are the reasons I opted for this … -

Catch-all field for unserialisable data of serializer
I have a route where meta-data can be POSTed. If known fields are POSTed, I would like to store them in a structured manner in my DB, only storing unknown fields or fields that fail validation in a JSONField. Let's assume my model to be: # models.py from django.db import models class MetaData(models.Model): shipping_address_zip_code = models.CharField(max_length=5, blank=True, null=True) ... unparseable_info = models.JSONField(blank=True, null=True) I would like to use the built-in serialisation logic to validate whether a zip_code is valid (5 letters or less). If it is, I would proceed normally and store it in the shipping_address_zip_code field. If it fails validation however, I would like to store it as a key-value-pair in the unparseable_info field and still return a success message to the client calling the route. I have many more fields and am looking for a generic solution, but only including one field here probably helps in illustrating my problem. -
