Django or Flask?
I am trying to build a webpage app that allows easy access to a tool that I built in python. The tool currently takes in csv files and then processes them and outputs a data frame with all necessary information. I guess I ultimately want a web app that allows a user to select csv files from their desktop and then outputs the data frame on the same page. What is the best software to do this? -

Ensuring one task of a kind is being executed at a time. (Multiple tasks of different kinds can be executed concurrentlly) celery python

A weird behaviour of get_media_prefix of Django
I am monitoring a weird behaviour in the working of my django application. Sometimes the get_media_prefix returns a mix between static and get_media_prefix. I ask here because I have not found any solution in the searchers and If anyone could have any idea because server and web application do not shown any error, It just returns the incorrect path since is a mix between two paths.

Django compare two users of a model and if one is the current user return the other user
I have this really simple friendship model that just consists of two users. After all if user1 is friends with user2 then user2 is friends with user1 automatically. I would like to filter all the results by the current user and if a row contains the current user I would like to return the other user. So basically I want to return all records if the current user is either userone or usertwo and if the current user is usertwo swap the values so the current user is userone. Currently it works but only one way using the following model, serializer and view Model: class Friendship(models.Model): userone = models.ForeignKey( User, on_delete=models.CASCADE, related_name="friendone" ) usertwo = models.ForeignKey( User, on_delete=models.CASCADE, related_name="friendtwo" ) created_at = models.DateTimeField(auto_now_add=True, verbose_name="created at") updated_at = models.DateTimeField(auto_now=True, verbose_name="updated at") class Meta: unique_together = ["userone", "usertwo"] def __str__(self): return "{} is friends with {}".format(self.userone, self.usertwo) def save(self, *args, **kwargs): if self.userone == self.usertwo: return "Same person friendship should happen mentally" else: super().save(*args, **kwargs) serializer: class FriendSerializer(serializers.ModelSerializer): profile2 = serializers.SerializerMethodField() class Meta: model = Friendship fields = [ "usertwo", "profile2" ] def get_profile2(self, obj): profile2_obj = Profile.objects.get(id=obj.usertwo.profile.id) profile2 = ProfileSerializer(profile2_obj) return profile2.data and view: class FriendList(generics.ListAPIView): permission_classes = [permissions.IsAuthenticated] serializer_class = … -

how to pass `request` info to Django form Widget
I am trying to pass a filter queryset for a Django form widget. Normally, I would do something like # views.py class MyView(SuccessMessageMixin, CreateView): model = MyModel form_class = MyCreateForm template_name = 'create.html' success_message = "You new object has been created." success_url = reverse_lazy('mymodel-index') # forms.py class MyCreateForm(forms.ModelForm): class Meta: model = MyModel fields = [ 'title', 'car', # etc ] widgets = { 'car': forms.widgets.Select( required=True, queryset=Car.objects.all(), # I need to filter this to the current user ), } However, I need to filter the queryset (in the car select Widget) to by the currently logged in user. I could try passing the user to __init__ from the View, but I don't know how to access that from the Meta subclass. Any pointers in the right direction would be appreciated. -

I am running my Django website using Amazon Linux EC2 instance. Everything runs correctly but for some reason, the actual front end of the website is not displayed. It even shows the title of the website in the search bar but can't display the actual content for me to interact with the website. It is just a white screen. Any help would be greatly appreciated. When I load the website, the GET requests display in my CLI: "GET / HTTP/1.1" 200 847, "GET /static/js/main.b1d3e335.js/ HTTP/1.1" 302 0, etc. I'm not sure what to try next. I used the collectstatic command for Django so I am thinking there may be a problem with the static files. But it is weird that my actual title of the website displays in the search bar but everything else is simply a white screen. -
Is it possible to include a view directly from the html?
I would like to know if it's possible, with Django, to include a view in another view like: Declare a view: def ads(request): param = ["first_ads_title"] return render(request, "blog/ads.html", context={"param": param}) With the following html : <div>ads {{ param[0] }}</div> And be able to call it from another html view like: <body> <h1>hello article {{ article }}</h1> {% include "blog/ads" %} </body> To display first_ads_title in my body ?
