I'm stack with this problem, I have a model which has a generic relation that every model save the same field here.

Query filter isn't returning object
I'm trying to get this audience object, that currently has its date set to 30/07/2021 (tomorrow), using the following querysets: print("qset 1:",Audience.objects.filter(start_date__year=self.year, start_date__month=self.month)) print("qset 2:",Audience.objects.filter(start_date__year=self.year, start_date__month=self.month, lawyer=lawyer)) But it returns nothing. So I decided to try and check manually with those... aud=Audience.objects.get(id=3) print("lawyer:",lawyer,"date",self.month,self.year,aud.start_date.month,aud.start_date.year) if aud.start_date.month == self.month: print("month") if aud.start_date.year == self.year: print("year") ... and got the return I was expecting on the console lawyer: marcosv1 date 7 2021 7 2021 month year qset 1: <QuerySet []> qset 2: <QuerySet []> qset 3: <QuerySet []> Can anyone identify the issue on this? I've spent several hours, with nothing coming to mind. -

Adding data to Django
I'm working on an existing, fairly large, Django application. It has the 'django.contrib.auth' app in settings.py so it already has User and Group models. I'm trying to use the Group to restrict a list of users in two ways: Hide a web page element (button) from users are in a new group "guides" Prevent the same users from being able to invoke the API endpoint URL directly I think I can do this by adding the new group "guides" to the Group model and then adding a list of users to that group. My question is how to create the new group and add the list of users to that group in a way that can be moved to our Dev, State, and Prod environments, but only occur one time during deployment (CircleCi). Any suggestions or ideas would be greatly appreciated, thanks! Doug -

Django admin - customize form-field
I need to customize a form in the admin-panel. One form's field is a long combobox (2000+ positions). It should be like when I type some text and get filtered positions. I can implement it in HTML-file with select2, but how can I include it in Django-admin panel? The additional dificulty is this field is inside inlines. Maybe, there is a better way to implement it. -

Does Django have any front end features?
I was wondering if the Django framework had any frontend features? I've heard quite a lot about Django, especially about their backend features, but I'm uncertain if Django has any frontend features too (as does React, Vue.js). I'm not as good at JS as I am at Python, so I was just trying to maximize the features for Django. Thanks. -

How to email a unique link to user django allowing them to confirm availability for an event (and update the database as well)
Here is the problem: I have a model called invite and a model called person. An invite is associated to a person and a person only and it has a field called status. How can I send generate a url that I can then send to the person through an email so that if they click they can confirm availability to the invite and update the status. I am thinking about using the UUID of the invite and adding a line on the urls.py calling a view that updates the status of the invite with uuid. But I wonder if there is a better way that doesn't expose the UUID. -
How to call a function that requires argumets in a template - Django
I have the following button: <a href="{'url acceptdonation pk = donation.pk'}" >Delete</a> In my acceptdonation function: def acceptdonation(request, pk): deleteitem = Donation.objects.filter(id = pk) deleteitem.delete() return HttpResponseRedirect('/dashboard/') As you can see in the code above, I want to pass a pk into the function when the delete button is clicked, and delete the Donation associated with it. Something that seems so easy would not work, so I did research online. I found out that you can not pass arguments into a function from a template. How can I make it so when my delete button is clicked, the Donation associated with the pk gets deleted? -
How to use OneToOneField/ForeignKey fields in django admin fieldsets
I am trying to create an admin page for business managers to create and update db models easily, as they are not comfortable with relational db concepts. The model in question has its own fields and a 1:1 relationship with Django auth user model. This is a simplification of this model: class Student(AbstractTimeStampedModel): uuid = models.UUIDField(default=uuid.uuid4, editable=False, unique=True) owner = models.OneToOneField( "auth.User", related_name="student", on_delete=models.CASCADE ) # other irrelevant fields What I would like to achieve is to be able to create or update a student owner's first_name, last_name and email trough the StudentAdmin class. This is a simplification of the admin class in question: class StudentAdmin(admin.ModelAdmin): fieldsets = ( ( _("Personal information"), {"fields": ("owner", "phone")}, ), ( _("Additional Information"), {"classes": ("collapse",), "fields": ("interest", "deactivated")}, ), ) The owner included in the fieldsets attribute works just fine, but it is a dropdown and it is required to open a new tab to create/update the owner. I have tried to use owner__first_name, etc. or owner.first_name, etc. within fieldsets, but it is not working. I get the following error: Unknown field(s) (owner__email, owner__first_name, owner__last_name) specified for Student. Check fields/fieldsets/exclude attributes of class StudentAdmin.

Can I decorate a Django REST Framework ModelViewSet Methods?
Django REST Framework ModelViewset offers the standard methods to update / create / retrieve objects. I would like to overwrite these method in the sense that they should keep their original behaviour as given by ModelViewSet, but just add to that a check in the beginning if the incoming request contains a certain query parameter. How can I do that? Eg. I would like to have class MyRessourceViewSet(viewsets.ModelViewSet): queryset = MyRessource.objects.all() serializer_class = MyRessourceSerializer def create(self, request): # Check if "key" query param is in request if "key" in self.request.data: create(request) # <<-- HERE call the "default" create method. -
How to add an additional python package to the Pipfile of a docker-compose project (DJANGO)?
Good day everyone, hope you're doing really well. I would like to start this question by prefacing that I'm a real newbie when it comes to setting up projects in the right way. Right now I'm working on a Django app with a friend that already has some more experience with web development and he had already set up everything with Docker-compose, that is, we have containers for our Django app, MySQL, Celery, RabbitMQ, etc. Now, I'm working on the back-end side of our project and need to add a new package to the list of packages the app container has: Smart-Open. The thing is, I have no idea how to do that. I'm on Windows, and using Git Bash to launch the docker-compose containers. What I've tried is opened the bash of the web app container and tried to pipenv install the module from there, but it was extremely slow, which made the Pipfile updating timeout: $ winpty docker exec -it whs_webapp_1 bash root@96caa176d252:/app/my_app_name# pipenv install smart_open[s3] Creating a virtualenv for this project… Using /usr/local/bin/python3.9 (3.9.6) to create virtualenv… ⠋Running virtualenv with interpreter /usr/local/bin/python3.9 Using base prefix '/usr/local' /usr/lib/python3/dist-packages/virtualenv.py:1090: DeprecationWarning: the imp m import imp New python executable in … -
Djoser: Password Reset with Username
I have developed an app using Django. It uses Djoser for user authentication. Problem: I have allowed user to register with already existing email addresses i.e. there might be multiple users using same email ID. So I can't reset password with the email field. Either I must use username only or the combination of username and email. How can I do this? Note:- Using base endpoint /users/reset_password/ but it requires email only to reset the password. -
Custom User PK (Primary Key) - Django - Python
I built a website with Python Django and part of it displays lines of already input data with the primary key next to it. Now I have separate user data by using a foreign key field in each one of my models and the specific user's data is only shown to that logged in user except that all the data regardless of the user is saved in one spot with the model shown in the admin interface(because I'm using foreign keys to separate data). My problem is that I need to display the primary key of just the logged-in user. Take this, for example, if User1 adds 1 line of data to their page then User2 adds 1 line of data on their page which will appear separate from one another, then User1 uploads another line of data, Then I user traditional primary key to number the data lines of User1 the numbers will be 1 and three instead of keeping them in numerical order of 1 and 2 and disregarding User2's data in the counting of the data. It's as if I need a separate primary key for each user. Sorry this is really hard to explain. I have … -
How do I make this (Django) comment form explicitly use the "POST" method on a post_detail page?
Working on the Mozilla diy blog app challenge. With tips from this tutorial, the comment form finally appears on the post_detail page. But adding a comment leads to a "Method Not Allowed" error. Searching on SO and elsewhere led me to believe the offending "method" is a "GET" method when it should be "POST". I understand the post detail page needs a GET method to display all the comments--but adding a comment via a form on that page needs to be using POST, but I am not sure how that's done--or why my code doesn't work. GitHub repo link is here. class Post(models.Model): post = models.TextField(max_length=1000) post_title = models.CharField(max_length=100) description = models.TextField(max_length=500) post_created_at = models.DateTimeField(auto_now_add=True) post_updated_at = models.DateTimeField(auto_now=True) author = models.ForeignKey(User, related_name="posts", on_delete=models.CASCADE) @property def num_comments(self): return Comment.objects.filter(post_connected=self).count() class Meta: ordering = ['-post_created_at'] class Comment(models.Model): comment_title = models.CharField(max_length=100) comment = models.TextField(max_length=1000) comment_created_at = models.DateTimeField(auto_now_add=True) comment_updated_at = models.DateTimeField(auto_now=True) commenter = models.ForeignKey(User, related_name="commented", null=True, blank=True, on_delete=models.CASCADE) post_connected = models.ForeignKey(Post, related_name='comment', on_delete=models.CASCADE, default=None, null=True) # class Meta: ordering = ['comment_created_at'] def __str__(self): return str(self.commenter) + ' : ' + self.comment_title[:40] def get_absolute_url(self): return reverse('post-detail', args=[str(self.id)]) #admin.py @admin.register(Comment) class CommentAdmin(admin.ModelAdmin): list_display = ('comment_title', 'comment', 'comment_created_at', 'commenter') list_filter = ('comment_title', 'commenter') search_fields = ('comment_title', 'comment') … -
