Django - Model Draft, Published, Revisions
I have a model that I use for creating project budgets. They approve one budget, but later on as they execute hours the budget might need to be revised and a user has to create a draft budget based on the one approved and make changes and submit to the manager for approval. I'm using Django and I'm not sure what I need to use for this. I've looked at django-reversion-API, django easy-mode and wagtail. But I'm very confused. I don't know what I need. Reversion, CMS, something related to state????? Any help would be appreciated. -

Make that django simple JWT have the same permissions as Django Admin
I'm developing an api in Django with DjangoRestFramework, and now I started to work with Tokens, (I'm using JWT with the djangorestframework_simplejwt library). What I want is to have the same permissions that I have in my django Admin in the token, for intance, I created a group for an specific app in my Django admin but when I use httpie with an user that wasn't supose to have permissions I can get all the data. Do you know a way to connect that permissions? This is the code that I wrote. from rest_framework.permissions import IsAuthenticated class ArticulosLista(APIView): permission_classes = (IsAuthenticated, ) # All other methods -
How to have one model property be a dropdown between attributes of another model?
Relatively new to Django. I think what I am trying to do is very simple but I've never done this before. "irrelevant2" is an attribute in my class first that I want to refer to a direct element in the class second (this part is working fine). Additionally, I want there to be a field in my class first that is essentially a dropdown menu that chooses between two elements of the class second and can only pick one. I understand that I need a form but so far have not been successful. My hunch says RELEVANT_VARIABLE should be a ForeignKey but I'm not sure how to attach it to a dropdown of either attr1 or attr2 from class second. class second(models.Model): attr1 = models.CharField(max_length=100) attr2 = models.CharField(max_length=100) class first(models.Model): irrelevant1 = models.ForeignKey(Account, on_delete=models.SET_NULL, null=True) irrelevant2 = models.ForeignKey(second, on_delete=models.CASCADE) RELEVANT_VARIABLE = models.ManyToManyField(second, related_name="team_selection") And then in forms.py class FirstForm(forms.Form): def __init__(self, *args, **kwargs): super(FirstForm, self).__init__(*args, **kwargs) self.fields[**not sure what to even put here**] = forms.ChoiceField( choices=[(o[**not sure**], str(o[**not sure**])) for o in Second.objects.filter(irrelevant2=self)] ) class Meta: model = second -
Django multiple forms in CreateView
I'm trying to show a view with two forms on it. The RoadCost form which will calculate the road's cost & pass it into the Road model so that when a Road is created it has the RoadCost associated with it. How can I show these two forms on the same CreateView & the pass it into the Road model? In theory, all the RoadCost should do is be next to the create view & allow the user to input the spent & allocated values it will do some calculations & then pass in the spent & allocated to the Road form ready for it to be created. I'm fairly inexperienced with Django, if there is a way to do this please let me know. model.py class RoadCost(models.Model): cost_spent = models.CharField(max_length=100) cost_allocated = models.CharField(max_length=100) class Road(models.Model): name = models.CharField(max_length=100) road_cost = models.OneToOneField( RoadCost, default=False, on_delete=models.CASCADE, primary_key=True, ) views.py class RoadCreateview(CreateView): model = Road fields = ['name', 'distance'] forms.py class RoadCostForm(forms.ModelForm): class Meta: model = RoadCost fields = ['spent', 'allocated'] -
How can I send context to Django in every page without sending from all the views
I am trying to create an eCommerce app and have the cart option in that. However, on every page of the site (or every view), I always type the code... context = { "no_in_cart":no_of_items_in_cart(request) } Where no_of_items_in_cart is a function to find the number of items in the cart. But I feel this is a waste of code and may have several inefficiencies. And also I am not sure on how I can send this code through auth_views, such as login or register views. Any help would be greatly appreciated. Thanks! -
Django Pass a Form's Field to a Model's Field
I am learning Django web framework by going through this example. In one of the view functions: def renew_book_librarian(request, pk): """View function for renewing a specific BookInstance by librarian.""" book_instance = get_object_or_404(BookInstance, pk=pk) # If this is a POST request then process the Form data if request.method == 'POST': # Create a form instance and populate it with data from the request (binding): form = RenewBookForm(request.POST) # Check if the form is valid: if form.is_valid(): # process the data in form.cleaned_data as required (here we just write it to the model due_back field) book_instance.due_back = form.cleaned_data['renewal_date'] book_instance.save() # redirect to a new URL: return HttpResponseRedirect(reverse('all-borrowed')) # If this is a GET (or any other method) create the default form else: proposed_renewal_date = datetime.date.today() + datetime.timedelta(weeks=3) form = RenewBookForm(initial={'renewal_date': proposed_renewal_date}) context = { 'form': form, 'book_instance': book_instance, } return render(request, 'catalog/book_renew_librarian.html', context) It assigns form.cleaned_data['renewal_date'] to book_instance.due_back. However, form.cleaned_data['renewal_date'] is not a models.DateField as defined by the BookInstance class: class BookInstance(models.Model): """Model representing a specific copy of a book (i.e. that can be borrowed from the library).""" id = models.UUIDField(primary_key=True, default=uuid.uuid4, help_text="Unique ID for this particular book across whole library") book = models.ForeignKey('Book', on_delete=models.RESTRICT) imprint = models.CharField(max_length=200) due_back = models.DateField(null=True, blank=True) … -
Having trouble rendering an array of images from an api (Django Rest Framework) response in React
Hi this is my first project in both React and Django Rest Framework and I need to figure this out to complete the project. The issue I'm having (I believe it's a React one) is that my api is returning an json response which React receives using axios which works fine since when I do the console log all the data is there and Im also able to pass the data to a tag, etc. I would like to display the photos that are being sent to by the api. The link is not the problem as I am able to view the photo in the browser using the link provided by the api. The problem is that I have multiple images in the api response that are set up as an array. As shown here: postmanResponse Response using console: enter image description here I guess essentially what I'm asking is there a way that I can make an array/object with the image array that my api is delivering so that I can then use it to show the picture in React? Any help will be helpful. Thank you! Here is my code for the React side: // Import Files … -

Setting up Django, Nuxt, with Nginx and docker
I am trying to create a docker image for all of the above services. I was able to get django set-up with a database and Nginx, but I am having a lot of trouble adding Nuxt to the mix and cannot get the Nuxt app to run properly and it is giving me constant errors that do not occur if I manually start the node server. I suspect that most of the issues are from auth and/or improper routing in Nginx, likely stemming from incorrectly setting up the appropriate files. Any advise on how to set-up these configuration files would be greatly appreciated! My folder structure is as follows. The dockerfile inside the app directory corresponds to the django app WebsiteProject/ ├── app/ │ ├── frontend-nuxt/ | | ├──Dockerfile | | └──nuxt.config.js │ ├── nginx/ | | ├──Dockerfile | | └──nginx_local.conf | └──Dockerfile └── docker-compose.yml docker-compose.yml version: '3.7' services: web: build: ./app command: gunicorn webapp.wsgi:application --bind 0.0.0.0:1339 --reload entrypoint: ./entrypoint.sh volumes: - ./app/:/usr/src/app/ - static_volume:/usr/src/app/static - media_volume:/usr/src/app/media expose: - 1339 env_file: - ./.env.dev depends_on: - db # - redis frontend: build: ./app/frontend-nuxt volumes: - ./app/frontend-nuxt/:/user/src/app/ expose: - 3000 ports: - 3000:3000 depends_on: - web command: npm run dev db: image: … -

How to stop Django 3.0 leaking db connections?

Django sys.exectuable not running in production mode
Code beneath takes an image and runs it through a python script. Everything works great locally. On production mode it does not seem to run (Droplet on digital ocean). I have tried to debug this as much as i can but i cant seem to retrieve anything of use... import sys from subprocess import Popen, PIPE, STDOUT, run class ImageViewSet(mixins.ListModelMixin, mixins.CreateModelMixin, generics.GenericAPIView): parser_classes = (JSONParser, MultiPartParser, FormParser,) queryset = UploadImageTest.objects.all() serializer_class = ImageSerializer def post(self, request, *args, **kwargs): self.create(request, *args, **kwargs) inp = request.FILES.get('image').name out = run([sys.executable,'//Users//macbookpro//mywebapp//myprojectenv//Script.py',inp],shell=False,stdout=PIPE, text= True) if out.returncode == 0: stat = 'Success' else: stat = 'Fail' data = { 'info': out.stdout, 'status': stat, } return JsonResponse(data, status=status.HTTP_200_OK) The only difference on the production server is the path below which could be incorrect. out = run([sys.executable,'//mywebapp//myprojectenv//Script.py',inp],shell=False,stdout=PIPE, text= True) On the production server the code above returns as "Fail" which means that it is being processed. For the Script i don't get any feedback. Either the path is faulty or the script is. however i'm not sure how to check if the Script is attempting to run but failing. Any help would be appreciated. -
Django Suggested Pages by User Tracking
I have a project I'm working on similar to a website like Game Informer to try to learn more of django. So I have a section of the website for a blog, for videos, for reviews, and for news. Each has its own model. I'd like to associate a tagging system with each of these models, probably using a many to many field to a model that just contains tags. The part that I'm struggling with is figuring out how I could use this tagging system to generate a list of suggested articles for users that are logged in. I thought about creating a model with a foreign key to the user and a foreign key to the post, then in the view logic, create an object and save it to the model with the user and page visited. But I'm not quite sure how I would access the tags that this person visited the most. I'm also curious if there's a way that I can add more weight to the certain tags if a user has liked a post with those tags and less weight if they've disliked. Any ideas, suggestions, or guidance would be greatly appreciated. I'll post … -
Saving form data upon social login
I'm using Django Allauth. I have few social login buttons (Google, Twitter, Facebook). I also have a form if the user wants to sign up via email. The form contains a hidden field that contains the App ID (if they are on an Android device). If they sign up via email, I have made a way where I can capture that information through the POST request. However, how do I capture this hidden field's data and pass into a social adaptor so that I can save this App ID. class SocialAccountAdapter(DefaultSocialAccountAdapter): def authentication_error(self, request, provider_id, error=None, exception=None, extra_context=None): messages.error(request, "An error occurred while attempting to login via your social media account.") raise ImmediateHttpResponse(redirect('/login/')) def save_user(self, request, sociallogin, form=None): user = super(SocialAccountAdapter, self).save_user(request, sociallogin, form) print(self.request.GET) //This doesn't work, but this is what I've tried Is there a way I can get this local value passed along when a user does social sign up? -

Django Email Templates Rendering as Text
