Is it possible to add one mixin to every view in file automatically?
As in title. Is there a way to add, f.e. UserPassesTestMixin to every view in file without inheriting it in every one of them? Let's say it would look like this: Mixin: UserPassesTestMixin Test: def test_func(self): # Some condition # .../views.py class FirstSampleView(SomeView): # View code class SecondSampleView(SomeView): # View code My target is that FirstSampleView, SecondSampleView and every other view in this file would have automatically my desired Mixin with according test_func. -

Adjustable Forloop Range - HTML
I have an html file in my django templates that contains a forloop. I need to to have a range on the forloop that basically says the forloop will only loop through the first 10 attributes. The complication arrises when I need the range to be adujstable. I need something like a number input that keeps a varaible and then only loops through that many attributes in the forloop. I have been on it for a few days and havent made too much progress. I have worked with simple forloop ranges but havent found a way to make them adjustable. This is the forloop I have been working with. {% for post in filter.qs %} {% if post.image %} <img class="pdf_field_img" src="{{ post.image.url }}"/> {% else %} {% endif %} <div class="title">Morgan Hall</div> <div class="inspection_num">Inspection #</div> <div class="inspect_num">{{ post.count_building }}</div> {% endfor %} -

Gather values from checkboxes, multiple options selected
I am building a python/django application. I have an Exercise table, with 3 choices: body part, equipment, and category. I have used ajax to get all exercises. However, before I show any exercise, I want to filter them. On I want to be able to select multiple options in body part, equipment, and category. For example, I want all the exercise that targets the body parts back, abs, and core. Right now, I am able to only search for one body party part at a time in JS, but I can still select multiple options. if(resultsBox.classList.contains('not-visible')){ resultsBox.classList.remove('not-visible'); } sendSearchData(e.target.value); })``` this is my JS code. the sendSearchData is the function that calls my ajax. ```<div class="dropdown" id="body_part"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false"> <img src="{% static 'img/bodypart-icon.png' %}" Alt="Body Part Icon" style="height: 25px; color: black"> Body Part </button> <ul id="body_part_data_box" class="dropdown-menu" aria-labelledby="dropdownMenuButton"> {% for choice in filter.form.body_part %} <li class="dropdown-item"> <input type="checkbox" id={{choice.choice_label}} value = {{choice.choice_label}}" name="body_part[]" class="body_part"> {{choice.choice_label}}</li> {% endfor %} </ul> </div>``` This is the HTML code for how I created my drop down menu.

FormSet with different Form value
I would like to have several form according to the day. That's why using FormSet object is a good idea. Each Form is dynamically changed according to the day. I would like to display several Form, each of them with different day.

Django - Have a user logged in authentication check on every REST API call
I have this code of 2 views in Django. You will notice that each REST API call has a verify_login() function call that ensures that the request contains a verified JWT token. I'm wondering if there's a better way to implement this so that I don't have to have these lines specifically in every REST endpoint verify_response = verify_login(request) if verify_response not None: return verify_response I'm trying to follow the D.R.Y. (Do Not Repeat Yourself) principle of coding. It'd be nice if there was a cleaner way to represent this. I thought about maybe creating a module extending APIView that automatically has this and then all my Views extend that, but runs into the issue of having to call super().API_REQUEST() and then having to do the same if-statement check to see if it's None or not. class PostView(APIView): """ View for Post object * requires token authentication """ # Create post @swagger_auto_schema( request_body=PostSerializer, operation_description="Create a post object" ) def post(self, request): verify_response = verify_login(request) if verify_response not None: return verify_response serializer = PostSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) # get all posts @swagger_auto_schema( operation_description="Get all posts from the DB" ) def get(self, request): verify_response = … -

Method Not Allowed (GET): and one keyerror
I know this error is because of not adding the 'GET' method but in my program I don't really get the point how I have to use that method in here. In here,I'am trying to add a favorite button in the page describing the car's details. So if I think iam right, the favorite button is embedded within the cardetails page. And when the 'favorite button is clicked, the post method is activated and straight to the method. There, I capture the 'POST' data named 'favorite' from the form .and i store it in the session. Then after every loading of the 'cardetail' page the method, loading the detail page will check whether, if this car is favorite or not, and pass adequate Boolean to HTML.
