ADD multiple objects with form
I'm trying to do something which I would think is quite common, but I'm just really unsure how to realise it. I have modal 'Requirement'. Every requirement has there own name and unique code. I want to show form with REQUIREMENTS_CHOICES list with checkboxs. User can select checkboxes which requirements they need. How to make it in Django? models.py: class Requirement(models.Model): code = models.UUIDField(_('Code'), primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(_('Name'), max_length=250, choices=REQUIREMENTS_CHOICES) REQUIREMENTS_CHOICES = ( ('A', 'Name A'), ('B', 'Name B'), ('C', 'Name C'), ) -
Favorites are not being returned back to template? Django
On the list the page the user is able to select which aircraft that they want to favourite. I've set it up correctly, but it doesn't seem to be returning anything.

Dango - navigate hyperlink to a folder on disk
I would like to click on a hyperlink in my Django template that navigates to an arbitrary URL such as file:///C:/my_dir/folder This URL works if I paste it directly into the address field of a browser, but does nothing if I click on a hyperlink in my Django app that resolves to that URL. I've also tried implementing it using the template - view protocol for Django but in my view neither of these seem to work return HttpResponse(html_filepath)orreturn render(request, html_filepath, context) -

Django how to tie device to user using token
I have a django app that uses the Django REST Framework with the Django OAuth Toolkit and django-rest-framework-social-oauth2. Each user has a raspberry pi that can come with a preloaded token. When users login to the website for the first time they are asked to enter the token that they got and is associated with the device. The device then should be tied to the user and is supposed to download configuration linked to the user profile. I was thinking that I could create an oauth client_id/secret for each device, and only give the user the client_id, and tie the credentials to their account once they enter it. The device could then access an API endpoint and see user specific data. Is there any way to do this? Any other suggestions to solve this problem would also be welcome! -

Multiple object types references in Django
We are currently running with the following configuration to avoid other issues so for the question, let's assume this is a must and we can not change the Models part. So, at first, we had the following models: class A(Model): b = ForeignKey(B) ... set of fields ... class B(Model): ... Then we added something like this: class AVer2(Model): b = ForeignKey(B) ... ANOTHER set of fields ... Assuming an object in B can only be referenced by either A or AVer2 but never both, is there a way to run a query on B that will return, in runtime, the correct object type in the query result (and the query has both types in it)? You can assume that an object of type B holds the information regarding who's referencing it. I am trying to avoid costly whole-system code changes for this. Thanks! -
What to do to run makemigrations/migrate on heroku when deploying changed models from github?
I have deployed app from github repository to the heroku account of my customer as collaborator but this time I had to add some new models. However I realized that when I deploy my changes from github heroku does not run makemigrations and migrate. I I read some answers on stackoverflow and understood this is how it is supposed to be. However my question is what should I do ? What is the best practise to deploy change models to heroku app. (I assume it is not deleting and recreating my app again since customer already has data there.) -

Store two types of value in single Django model field
I am learning django by creating a polling application. For starters I have three models User, Question and Choices. class User(....): .... Questions_voted = models.ManyToManyField(Question) .... this means that a user to vote for as many questions as he wants. Next is The Question Model which is simple and just store question text and number of people voted for it. class Question(models.Model): question_text = models.CharField(max_length=500) vote_count = models.IntegerField(...) next is Choices which have a choice_text and refers to the question it belongs to. class Choice(models.Models): choice_text = models.CharField(models.Model) question = models.ForeignKey(Question,...) Now I want to store information about what choice a user selected for a question. It is very clear when you think of it but I am stuck because of lack of knowledge of types of fields in django models. -

Prevent Django from logout through url before hitting enter
So I have created a Django-app with a login form and using login(request, user) in my view.py to login the user. This is the main page and has the location mypage.com. I also created another function in my view.py called log_out: def log_out(request): logout(request) return redirect('/') This function is used to log out a user using the url: mysite.com/logout as defined in my url.py: url(r'^logout/', views.log_out, name='log_out'), This is working to log out the user, however the user is being logged out as I'm typing in the logout-url into the address-field of my browser, and before hitting enter to go to that endpoint. I would like it to not log out the user when typing in the url, and wait until I'm "entering" the site. Can anyone help me with this one? -
Django ManyToMany relationship details
I want to build a website in which users can send words to each other using Django. When a user deletes a word, that word will be deleted for only that user. I have a working website; the only problem is when a word is deleted, it is deleted for all users. How can I fix this problem, is it a problem which is related to ManyToMany relationships?

Efficient way in Django Models to store Items Purchased in a Transaction for a Commerce Store
I've created two simple Django Models. One model simply holds the bill details. The other one holds the list of items purchased in that Bill, linked through a foreign key relation. I'm stuck at a problem of creating a very large database with this implementation. Model Classes : class Bill(models.Model): seller_id = models.ForeignKey(User , related_name = 'bill') amount = models.DecimalField(max_digits = 7 , decimal_places = 2) customer_id = models.ForeignKey(User , related_name = 'bill') and class BillItems(models.Model): bill = models.ForeignKey(Bill , related_name = 'items') product = models.ForeignKey(Product , related_name = 'items') quantity = models.DecimalField(max_digits = 6 , decimal_places = 3) Now as I see it , after some time my database(MySql) would have a very large number of Bill Items' instances. Is there a better way to implement such a structure? OR Is there a way to optimize this structure? Thanks and Regards. -

Djano Rest Framework - Extra Data at Save on Update
I am experiencing some strange behaviour using the .save(field = 'value') on the perform_update event using Django Rest Framework inside view.py. I am updating a specific field, adding logic and adding additional data to the serializer before saving data in the model/database based on a the customer's response/api call. Each time I test by setting an PUT (update) as 'yes' and then 'no', the .save() randomly works. I think sometimes the save() happens before the variable gets set and passed to .save(). I am fairly new to Django and Python so I may not be doing this correctly. I have also tried declaring variables and then passing those variables into .save(field='created variable') but I still get the same strange behaviour. Here is my code: def perform_update(self, serializer): # Change depending on customer's repsonse. # customer_acceptance is "yes" or "no" from front end print(serializer.instance.customer_acceptance) if serializer.instance.customer_acceptance == 'yes': serializer.instance.creditor_status = 'accepted' serializer.instance.agreement_acceptance = 'yes' if serializer.instance.customer_acceptance == 'no': serializer.instance.creditor_status = 'customer_rejected' serializer.instance.agreement_acceptance = 'no' if serializer.is_valid(): print(serializer.instance.creditor_status) serializer.save( customer_response_date = datetime.datetime.now() ) -
Django recursive query on non-symmetrical Many-to-Many to the same model
I'm offering services to companies (many-to-many between Service and Company). To structure my services, I use a tree-like structure using Django's many-to-many field. So, a service can contain multiple other services. The question: how can I retrieve all services a company has? Using company.services, I only get the services directly related to that company. I need the directly related ones + included_services (in a recursive way). class Company(models.Model): services = models.ManyToManyField(Service) class Service(models.Model): name = models.CharField(max_length=255) included_services = models.ManyToManyField("self", blank=True, symmetrical=False) -
Autogenerate seats in django mode
I'm developing a bus reservation website using Django. I have two model files in different Django apps. One of the model class is Bus and another one is seats. There is capacity integerfield in bus class. I want that when a bus is created in the database, automatically a loop runs and creates the seats equal to the capacity in the bus class. Maybe you'll get a clearer view after looking at my models files. \src\book\models.py from django.db import models from django.contrib.auth.models import User from web.models import Bus, Route class Booking(models.Model): class Meta: verbose_name_plural = "Booking" user = models.ForeignKey(User) #session = models.ForeignKey(sessions.Sessions) name = models.CharField(max_length=50) gender = models.CharField(max_length=10, choices=(('Mr', 'mr'), ('Mrs', 'mrs'), ('Ms', 'ms'),)) age = models.IntegerField() email = models.EmailField() phone = models.IntegerField() bus = models.ForeignKey(Bus, default='') def __str__(self): return self.name class Seat(models.Model): class Meta: verbose_name_plural = "Seat" for seats in range(1,int(float(Bus.capacity)+1.0)): id = models.AutoField(primary_key=True) bus = models.ForeignKey(Bus) def __str__(self): return str(self.id) class Ticket(models.Model): class Meta: verbose_name_plural = "Ticket" seat = models.ForeignKey(Seat) bus = models.ForeignKey(Bus) route = models.ForeignKey(Route, default='') def __str__(self): return str(self.id) \src\web\models.py from django.db import models from django.core.exceptions import ValidationError class Route(models.Model): class Meta: verbose_name_plural = "Routes" BUSFROM = ( ('Delhi', 'Delhi'), ('Jaipur', 'Jaipur'), ('Ajmer', 'Ajmer'), ) BUSTO … -

Create custom abstract view class inheried from APIView
I am working in DJango with DJango REST Framework module. For each model I make, I have a view: class CustomAPIView(APIView): renderer_classes = (JSONRenderer, ) permission_classes = (IsAuthenticated, ) @csrf_exempt def post(self, request): raw_data = serializers.SearchStateSerializer(data=request.data) if raw_data.is_valid(): searched_data = serializers.ShowStateSerializer(data=serializers.State.objects.extra(where=raw_data.data['where'], order_by=raw_data.data['order_by']), many=True) return JsonResponse(paginate_data(searched_data=searched_data, request_data=raw_data), status=status.HTTP_202_ACCEPTED) else: return JsonResponse(raw_data.errors, status=status.HTTP_400_BAD_REQUEST) In this code, there are 3 constraints that change: SearchStateSerializer ShowStateSerializer State(Model) So I want to create an abstract in which I only specify these 3 things and the view works. How can I do this? I searched a lot but with no luck. It is must that these 3 constraints are supplied or it will throw error. -
Mocking forms in view unit tests
I can't seem to be able to mock the behaviour of a form when unit testing views. My form is a simple ModelForm and resides in profiles.forms. The view is (again) a simple view that checks whether the form is valid and then redirects. views.py from django.http import HttpResponseRedirect from django.shortcuts import render from django.urls import reverse from profiles.forms import ProfileForm def home(request): form = ProfileForm() if request.method == 'POST': form = ProfileForm(request.POST) if form.is_valid(): profile = form.save() return HttpResponseRedirect(reverse("thanks")) My test looks like this: class TestViewHomePost(TestCase): def setUp(self): self.factory = RequestFactory() def test_form(self): with mock.patch('profiles.views.ProfileForm') as mock_profile_form: mock_profile_form.is_valid.return_value = True request = self.factory.post(reverse("home"), data={}) response = home(request) logger.debug(mock_profile_form.is_valid.call_count) # "0" is_valid is not being called on the mock, which means ProfileForm is not patched. Where did I make a mistake?
