How to create APIs for UserProfile with rest framework?
I have created a UserProfile model with OneToOne relationship with User model. The UserProfile model is shown below. from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) mobile_number = models.IntegerField(blank=True, unique=True, null=True) profile_image = models.ImageField(upload_to="media", blank=True ) current_location= models.CharField(max_length=300, unique=False, blank=True) created_at = models.DateTimeField("created at", auto_now_add=True) university = models.CharField(max_length=100, blank=True) def __str__(self): return self.user.username def create_profile(sender, **kwargs): if kwargs['created']: user_profile = UserProfile.objects.create(user=kwargs['instance']) post_save.connect(create_profile, sender=User) The serializer class is shown below. from rest_framework import serializers from .models import UserProfile class UserProfileSerializer(serializers.ModelSerializer): class Meta: model = UserProfile fields = ( 'mobile_number', 'current_location' ,'university','profile_image') Iam using token authentication. How can I use the ListCreateViewand other classes to implement the post, put ,get and delete method in the best way possible. I also need to validate these data before saving(like mobile_number length should be 10 and mandatory) -
how can I improve my helpers / models to give me true / false instead of returning me invalid token view?

Methods from a single view to different endpoints: keep APIs for HTML and for JSON separated (Django Rest Framework)
Could you help suggesting how to keep coding style organised to keep endpoints from HTML and JSON separated, in Django Rest Framework ? In Flask I am used to keeps endpoints for serving Json, and ones for serving HTML, separated, like: @application.route('/api/') def api_root(): #... return jsonify({'data' : data}) and @application.route('/home/<string:page>/', endpoint='page_template') #... return render_template(template, page) And so I could serve the APIs like: /api/page => serve the json for the page, say for AJAX etc. /page => serve the corresponding html page In Django RF, I read that a ModelViewSet can serve both. So I could keep everything in one place. However, when I come to map views on the router, I would have all the endpoint served respect the path related my model, they would be all sub-path of /api Could you help in advising a good coding practice to make use of ModelViewSet, and route endpoints for html separated from APIs ? This is the example Im working on, my doubts are in comments: from rest_framework import viewsets from rest_framework import generics from rest_framework.decorators import action from rest_framework.response import Response from .serializers import PersonSerializer from .models import Person class PersonViewSet( viewsets.ModelViewSet): queryset = Person.objects.all().order_by('name') serializer_class = PersonSerializer … -
how to execute a user supplied python script on button click django

Django receive a signal when a model value gets changed from a different application or when manually edited in database
I'm currently in a peculiar situation where I am not allowed to use a new database even though the product owner wants a new and improved application. This means that my new application will have to work with the old database. This database doesn't use foreign key constraints, which makes the usage of modules such as Django tables 2 nearly impossible. The solution I thought up is the following: Add in an extra foreign key field to required tables Users in the old app change an id of sorts, let's say team id of a news article Django app sees this change, finds the correct team model and links that team model to the foreign key field What I've tried so far to achieve this: Add in a custom save method to my model. This does work when I change the model with a view or CLI, but doesn't do anything when I manually change a value in the database or use a different application to change any values. class Team(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=100) intra = models.ForeignKey(Intra, on_delete=models.DO_NOTHING) def save(self, force_insert=False, force_update=False): print("test") The next solution I tried is using a receiver. This again works in CLI … -

How can I create new 'draft' object with class based UpdateView before form filling?
I have a product model that has a lot of field. When user click to "Create New Product" I want create new object (just create object that it has id, seller, draft status), and show blank form. Because I want to use Ajax asyncronous upload to this object. User fills the object's other fields (like upload images) and save. Also user should be able to edit own draft products on own dashboard. First problem: I used UpdateView, but If I override get_object method and I click "Create New Product", django calls twice this method and create two object?! I want call just one time. Second problem: When users wants to edit draft items, they go to dashboard and edit someone. Should I create new class-based view for this or can I use same view for both operation? Maybe I can add get_or_create method to my get_object method, is It possible? my model: class Product(models.Model): seller = models.ForeignKey("auth.User", on_delete=models.CASCADE, verbose_name="Seller", default=None) category = models.ForeignKey("Category", on_delete=models.CASCADE, verbose_name="Category Name", blank=True, null=True) title = models.CharField(max_length=50, verbose_name="Product Title", blank=True, null=True) status = models.IntegerField(choices=((x.value, x.name.title()) for x in Status), default=Status.TASK) images = models.ManyToManyField("ProductImages", blank=True, null=True) my class-based view: class ProductCreateViewTest(LoginRequiredMixin, UpdateView): template_name = 'product/add.html' form_class = … -

Django template rendering HTML elements in the wrong order
This is a Django beginner question (or possibly just an HTML problem). I'm rendering a very simple HTML page with a template (I'll make it look nice later). It has two divs, each containing a header and a table. If I print the rendered content in my view, it looks right, but the HTML delivered to the browser has both headings, then both tables.

django: adding custom permissions stopped working

Pycharm identifies new Django test file as a unittest, not a django test
How do I tell pycharm that the new test file I created is a django test file, and not a unittest file? I have pycharm setup with a django project. I can run all django tests as django tests with the test runner. I created a new test file, wrote a simple unittest on it. The tests run fine with manage.py and with the run configuration for running all tests. But, when I try to run an individual test within the new test file from pycharm it fails because pycharm is trying to run it as a unittest instead of a django test. As shown in the screenshots below, pycharm considers this new file a unittest file, not a django test file. Yet both files are in the same directory, both implement a class that extends Unittest, and both have tests. -

Register multiple routes in Django DRF - using and calling methods in ModelViewSets or Generics
I want to understand how to use Django DRF to register: two different endpoints, and only one endpoint making use of custom fields Please show the differences in using ViewSets and Generics. These are my attempts. I came from Flask, and found very clear to define multiple end-points with decorators. Flask - example endpoints to get a list of objects,last object option 1 @application.route('/people/', endpoint='people') def people(): # return a list of people pass @application.route('/last/', endpoint='last_person') def last_person(): # return last person pass option 2 @application.route('/people/', endpoint='people') def people(): field = request.args.get('last', None) if field: # return last person from list of people else: # return list of people I understood the benefit of DRF may be consistency and read the documentation, but found cumbersome and wish to understand more clearly how to make use of ModelsViewSets and Generics to see the benefits VS flask. Please help with an example to fetch a list of users, and last user.
