Django ModuleNotFoundError: No module named 'models'
I'm building a web app in Django to purchase movie tickets. All the logic handling the database is in the 'ticket_handler' app. The actual website is in the 'movie_site' app and I'm building a restful api in the 'ticketing_api' app. Whenever I try to import something from one app to another, I get a "ModuleNotFound" error.

How to send image from Expo Image Picker to Django REST using axios
I have spent about a week on this and cannot understand what is going on. I need to upload images from React-Native (EXPO) to Django REST. It seems to be that axios is sending an object instead of an image (I think). React Native EXPO Image Picker/Axios: const pickImage = async () => { // No permissions request is necessary for launching the image library let result = await ImagePicker.launchImageLibraryAsync({ mediaTypes: ImagePicker.MediaTypeOptions.All, allowsEditing: true, aspect: [4, 3], quality: 1, }); if (!result.cancelled) { const formData = new FormData(); formData.append("image", { uri: result.uri, name: "image.jpeg", type: "image/jpeg", }); try { const response = await axiosInstance({ method: "post", url: `/api/businesses/84/upload_image/`, data: formData, headers: { "Content-Type": "multipart/form-data" }, }) console.log(response.data); } catch (error) { console.log(error.response.data); } } }; Django API: class BusinessProfileViewSet(MixedPermissionModelViewSet): """ API endpoint that allows business profiles to be viewed, created, or edited.

Raw sql query issue in Django
I am trying to to make an SQL query to impliment the answer given here. The user suggested I try doing a raw sql query to solve. I am having issues implimenting what he suggests. For example, this is what I have so far. ingredients = ["eggs", "bacon", "salt"] recipes = Recipe.objects.raw('select whattocook_RecipeIngredients \ from whattocook_Recipe a \ inner join whattocook_RecipeIngredients b \ on a.id = b.recipe_id and b.ingredient in (ingedients) \ group by recipeingredients \ having count(*) >= 2') But this does not work. His answer says to do this recipe_list = Recipe.objects.raw('select a.* from app_Recipe a inner join app_RecipeIngredients b on a.id = b.recipe_id and b.ingredient in ("egg", "bacon", "rice") group by a.* having count(*) >= 2') maybe replace app_ with your project name, replace a.* with list of column names. So I think I am misunderstanding which columns I need to replace, given my code gives me this error. django.db.utils.ProgrammingError: column "ingedients" does not exist LINE 1: ... on a.id = b.recipe_id and b.ingredient in (ingedients... ^ HINT: Perhaps you meant to reference the column "b.ingredient".

Passing Extra context to ListViews in Django

How to access object data from 'self' in get_context_data?

Can I serve a react app (with react router) from a specific endpoint?
I have a Django app. Most of the endpoints for this app will serve up a template. However, I would like one endpoint, lets say example.com/xyz, to serve a React app. This react app uses routes, so it would manipulate the url path. My question comes in two parts: If it is possible to do this, how can I ensure React router keeps the original /xyz endpoint in the path before adding whatever else to it? How can I configure Django to return the react app for ANY endpoint that begins with /xyz? -
Django: I want to track from which url a request was made?
in the TestQuestionList class, the get function must receive an id to return id, I thought that I could do this with the help of request.get_full_path()example on the bottom class TestQuestionList(APIView): def get(self, request): obj = Test.objects.get(id = request.get_full_path()) romms = TestQuestionBlok.objects.filter(id__in=obj.questions) serializer = TestQuestionSerializers(romms, many=True) return Response(serializer.data) but request.get_full_path() instead of /tests/api/ (where the request was made from) returned /api/question/ why? This is part of the code from where the request was made useEffect(() => { axios({ method: 'GET', url: 'http://127.0.0.1:8000/api/questions/', }).then(response => { setAllQuestions(response.data) }) }, []) Thanks in advance for your replies -
Django modifying login view has no effect
Long story short: No matter what I do with the login view, it won't change the behavior of the login form, I can delete my views altogether (and urls) and it still works, so it must be picking it up from somewhere else. From where and how do I change that? Long version: I was following a tutorial to implement login, logout and registration with django built in features, it is actually working fine but when I was trying to modify the login view I just realized that no matter what I tried to do in the view, it wouldn't change the behaviour (I was trying to redirect to a different page if the user was already logged, for instance). I started playing around to see what I could change and how it would reflect, even adding prints, but nothing happened, until I decided to try replacing all the code inside the login view function with pass, AND IT STILL WORKED! It happens the same with the logout view, but it doesn't with the register view. I don't understand what's going on. I tried to find something online, but I couldn't find anything related to this exact issue. This is … -

Django ORM filtering using expression against multiple fields

Django CBV inheritance not working as expected
I use these two classes to get the context data and check permissions respectively: class RestaurantView(View): def get_context_data(self): ctx = {'restaurant': get_object_or_404(Restaurant, slug=self.kwargs['slug'])} return ctx class ManageRestaurantMixin(LoginRequiredMixin, UserPassesTestMixin, RestaurantView): def test_func(self): ctx = super().get_context_data() return ctx['restaurant'].owner == self.request.user Now the first one is working, so when i don't need permission i get the expected behavior, for example with this DetailView: class Info(RestaurantView, DetailView): model = Restaurant context_object_name = 'restaurant' template_name = 'restaurant/info.html' But then if inherit from ManageRestaurantMixin the permissions are checked as expected, but the context object is not working and the template displays an empty form: class EditInfo(ManageRestaurantMixin, UpdateView): model = Restaurant context_object_name = 'restaurant' template_name = 'restaurant/edit_info.html' fields = ['name', 'address', 'logo'] success_url = '/account/myrestaurants' I get that the context gets overwritten, but i don't get how. How can i solve this? Is there a better way to handle this kind of situations? -
