Unable to insert the data into model users group
I have created a custom User model in Django app users_and_auth to use the default authentication of the Django. models.py class Users(AbstractBaseUser, PermissionsMixin): email = models.EmailField(max_length=255, unique=True) first_name = models.CharField(max_length=255, blank=False, null=False) last_name = models.CharField(max_length=255, blank=False, null=False) profile_picture = models.ImageField(upload_to='profile_pictures/', max_length=None, null=True, blank=True) is_active = models.BooleanField(default=True) objects = managers.UserManager() USERNAME_FIELD = 'email' I want to categorize registered users in two different user groups say x and y. So, I added two new records in Group model of auth app i.e auth_group which was created when I run the first migration of the app. Then I run the migration of app users_and_auth which created 3 new models users_and_auth_users, users_and_auth_users_groups and users_and_auth_users_user_permissions. Now, these are the tables of database - As, shown in screenshot there is table in database called users_and_auth_users_groups which categorize users in groups listed in table auth_group. The table is described as below - I want to push the user_id and group_id in this database table from an APIView. What I don't understand is which exact app or model I will have to import so that I could use model.object.create(). -
Django - Ajax not sending data correctly
In my project, I set up an AJAX call, which grabs what a user entered inside an input, sends it to the server, and once returned back to AJAX, it should be displayed inside a div. However no text is displayed in the div as expected. Here is my HTML (signup.html): <form id="signup_form" action="{% url 'signup' %}"> {% for field in form %} {{ field }} <br> {% endfor %} <button class="signup-btn btn btn-primary">Sign up</button> </form> <div id="testbox"></div> JS: var delayTimer; $('#signup_form').keyup(function() { clearTimeout(delayTimer); delayTimer = setTimeout(function () { // Username input in my form(created by Django forms) var usernameVal = $("#username_signup").val(); $.ajax({ url: '/users/ajax/signup', data: { 'usernameVal': usernameVal, }, dataType: 'json', success: function(data) { $('#testbox').text(data['usernameVal']); console.log(data['usernameVal']); } }); }, 1000); }); views.py: // Function to handle AJAX request def ajax_signup(request): form = SignupForm(request.GET) if form.is_valid(): print("It works") return JsonResponse({'usernameVal': form.cleaned_data.get("usernameVal")}) else: print(form.errors) return JsonResponse({'hello': 'not working'}) // View that renders the form(template is the html provided above) def signup(request): context ={} form = SignupForm() context['form'] = form return render(request, 'signup.html', context) The Message "It works" is displayed to the console, therefore the form is valid, however when performing print(form.cleaned_data.get("usernameVal")), I get returned None to the console. This means the … -
Filter Only Custom Permission for the model(Django)
I know i can filter list of the permissions for a specific modal using below orm Permission.objects.filter(content_type__app_label=app_name, content_type__model=model_name) but actually i want to filter custom model permissions and default modal permissions for the specific modal separately. for example default_permissions = some_orm custom_permissions = some_orm Here custom permissions means, permission defined by user inside Meta class of any model. -
Django InlineFormSet DeprecationWarning on can_delete = False
I'm trying to remove the Delete checkbox from the inlines. Let's say I have two models with one to one relation: models.py class Users(model.Models): .... class Extra_Fields(models.Models): user = models.OneToOneField(Users, on_delete=models.CASCADE) other_fields = .... I want a form to update both of the related object at once: class CustomInlines(InlineFormSet): model = Extra_Fields fields = ['custom_fields'] can_delete = False class CopywriterProfile(UpdateWithInlinesView): # boring stuff inlines = [CustomInlines] As you can say I'm using UpdateWithInlinesView. When I try to load the form I get the following error: DeprecationWarning at /profile/ Setting `CopywriterInline.can_delete` at the class level is now deprecated. Set `CopywriterInline.factory_kwargs` instead. I suggest to use factory_kwargs to set can_delete = False, but I didn't find any documentation. Someone can help me? -

Python: Filter objects by Concat() and order by the same concatenation
In my Python/Django API project I need to get a quesryset from a model filtered by a concatenated combination of two fields and order by the same concatenation. However I only know to filter by one field like shown below. Requirement: TimeTable has two fields "date" and "time". I need to list data where the combination of both these fields are greater than current date time. Code: current_time = datetime.now() timetable = TimeTable.objects.filter(user=user_id, date__gte=current_time.date()).order_by(Concat('date','time')) How can I accomplish this? -
How to create a fillable and savable pop-up form in Django project?
How do I trigger a fillable pop-up when the user clicks on an image, on a Django web app that the winds up sorting the following result ? There many features that come after that as shown in here, that can wind up like that, and resulting on this final result, but so far I couldn't find a solution to that first step (my sole focus) on other websites. Is this something that can be done with HTML, CSS, and JS only, or do I have to use python to then save the data to the SQLite database ? If someone can suggest or hint at the steps that I need to follow to get this done I would really appreciate it. -

Cannot populate database table during Heroku deployment?
I have a django app that runs perfectly well on my local server. Unfortunately, when I deploy it onto Heroku, the behaviour doesn't work as expected. I can see that it's a database related issue as my dropdowns which are supposed to load a list of values from my database are empty in production. I have checked on Heroku in the 'Ressources' section of my application and there is a database; it also contains all my project tables (django default tables + my main table). All the django default tables are properly populated (I compared them with my local postgres tables and it matched). Unfortunately, my main table is empty on Heroku, whereas it is populated as expected locally. I'm not sure to understand what has gone wrong, especially considering that the table itself has been recognized, yet it is empty. I've applied the command heroku run python manage.py migrate but it didn't fix the issue. My guess is that my database settings are correct for local deployment but not for Heroku deployment. Nevertheless, I'm not sure at all. I've tried replacing my db settings by the user/host/password/name provided by Heroku but it didn't work. Any guidance will be much … -

Integrate CoreUi React Template and python (Flask or Django)
I'm very new to CoreUi and I'm trying to connect CoreUi (Frontend) and Python (Backend) but everything I tried didnt work.. Does anyone of you know a good video or documentation which could help me ? I integrated React and Python (Flask) before in another project a couple of month before where I used this instruction from youtube: https://www.youtube.com/watch?v=YW8VG_U-m48&t=179s . I tried to integrate CoreUi and Flask the exact same way but it didnt work. I dont care if I use Django or Flask, I only want the connection to work... I also deleted the code where I tried to connect the frontend with the backend so I cant give you any code snippets or my webpack.config file. Hopefully anyone can give some instructions to simply connect the coreUi Template to python. I downloaded the coreUi template from GitHub (https://github.com/coreui/coreui-free-react-admin-template) -

How to LIMIT number of different choices in my model that user can save? - Python Django
I have model UserDraft. Inside that model I have pick_id with different choices represented in numbers when u go into Django Admin. I want each choice to be limited to max 5 times for each user to be picked. For example in this code I want to have user1, 1, hero1, user1, 1, hero2, etc....Also i would love to restrict that you cant pick same hero twice. models.py from django.db import models from users.models import User from heroes.models import Hero from django.core.exceptions import ValidationError class UserDrafts(models.Model): FIRST = "1" SECOND = '2' THIRD = '3' PICK_ID = [ (FIRST, 1), (SECOND, 2), (THIRD, 3), ] user_id = models.ForeignKey(User, on_delete=models.CASCADE, related_name="user_id") pick_id = models.CharField(max_length=20, choices=PICK_ID) hero_id = models.ForeignKey(Hero, on_delete=models.CASCADE) def save(self, *args, **kwargs): if self.__class__.objects.filter(user_id=self.user_id).count() >= 5: raise ValidationError('Maximum five picks are allowed per user') return super().save(*args, **kwargs) def __str__(self): return self.user_id.username class Meta: verbose_name = "UserDraft" verbose_name_plural = "UserDrafts" This save method that I used only limits user to pick more then 5 times.

Django REST framework: How to use multiple PKs in URL with class based views/serializer
I have two models (examples): class Container(models.Model): name = models.CharField(max_length=100) class ObjInContainer(models.Model): Container = models.ForeignKey(Container, on_delete=models.CASCADE) A Container can have N number of ObjInContainer. I'm trying to write a REST API to do two things: First: See all ObjInContainer from a single Container: # urls.py url(r'^container/(?P<container_id>\d+)/objects_in_container/$', ContainerObjectsListAPIView.as_view(), name='container_objects_list'), # views.py class ContainerObjectsListAPIView(ListAPIView): queryset = ObjInContainer.objects.all() queryset = queryset.prefetch_related('container') serializer_class = ContainerObjectsListAPIView # serializer.py class ContainerObjectsListAPIView(ModelSerializer): container = SerializerMethodField() class Meta: model = ObjInContainer fields = [ 'id', 'container', ] def get_container(self, obj): return str(obj.container.name) But this lists all ObjInContainer from ALL Container. How do I tell REST Framework that the Container it needs to get the ObjInContainer from is the one in the URL from <container_id> ? I suppose in views.py where I declare queryset = ObjInContainer.objects.all(), should really be queryset = ObjInContainer.objects.filter(container_id=container_id), but how do I access the <container_id> part of the URL in the view class? Any my second issue is how to detail a single ObjInContainer, by using two different IDs in the URL? # urls.py url(r'^container/(?P<container_id>\d+)/objects_in_container/(?P<obj_in_container_id>\d+)/$', ContainerObjDetailAPIView.as_view(), name='container_object_detail'), # views.py class ContainerObjDetailAPIView(RetrieveAPIView): queryset = ObjInContainer.objects.all() serializer_class = ContainerObjDetailSerializer # serializer.py class ContainerObjDetailSerializer(ModelSerializer): container = SerializerMethodField() class Meta: model = ObjInContainer fields = [ 'id', 'container', ] … -
