Python Django or Flask for web development?
I have intermediate Python skills and want to learn web development. Should I start with Django or Flask? When I search for answers I only see benefits or downsides of them, but not anyone saying which one is better. And since I don't have any experience, I cant decide. I know it always comes down to what you want to create etc. But what would you say, is better overall? Is it possible to answer that question? -

flutter and stripe (setupIntents)
I know this library flutter_stripe, which to me seems to be very limited in stripe interactions, it only does paymentIntent creation and that is basically it. Please do argue if I am wrong. I am looking forward to see if there are other packages, if any, for flutter to interact with stripe in more depth, I am trying to avoid Android/IOS native languages. I do these in backend: create stripe customer, create setup intent for each customer as they try or either add bank card or make purchase. I am looking forward that client will interact to stripe for the following: 1 Confirm setup intents 2 Send card data to stripe Another question, could you please assess my payment flow? If it is faulty please recommend another way Once setupintent is confirmed for the user, they hit backend for whatever purchase they want to make, backend contacts Stripe, fetches the setupintent, creates and confirms the paymentintent. Thank you, I appreciate help. -
How to pass a value in a Django drop down from a ModelForm
I want to display different fonts for users from a drop-down. The drop-down derives its values from the model which has choices option. The problem is when a certain font is chosen, it saves well in the database but the “value” is not caught.

Retun data from a Django view after a javascript AJAX POST request
I am using Javascript to send an asynchronous request to a Django View. The View is able to receive data from the POST request, but I can't seem to return a message to confirm that everything worked. I was expecting that xhttp.responseText would contain the message Thankyou, but it is empty. The html part looks like this: <textarea id="message"></textarea> <input type="submit" value="Send" id="send_button onclick="submit_message()"/> The javascript looks like this: function submit_message(){ document.getElementById("send_button").value="Sent - Thankyou!"; message = document.getElementById("message").value var xhttp = new XMLHttpRequest(); xhttp.open("POST", "/send-message"); xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xhttp.send("csrfmiddlewaretoken={{ csrf_token }}&message="+message); console.log('Sent POST request') console.log(xhttp.responseText) } I was hoping that xhttp.responseText would print Thankyou to the console. The Django View function looks like this: def send_message(request): message = request.POST.get('message') print(message) return HttpResponse('Thankyou') The message variable prints out as expected, but Thankyou doesn't seem to be returned. I am doing AJAX with JS for the first time, so I expect I've just misunderstood something simple. -

How to make user specific forms?
So I want to make it so a "Tutor" can select a "Student", now each tutor has a different set of Students so the drop down list needs to be unique. So this is the part of forms where question comes from, tutor1 get's passed through by response into views, then from views it needs to be passed into the form so Students.objects.all displays all of the students that tutor1 has. (The query set part is fine and I believe the Field is also correct) the part that doesn't work is passing in response or passing in the tutor1 into the form and so far I can't find anywhere how to do this. student = forms.ModelChoiceField(queryset = Students.objects.all(tutor=tutor1.id)) This is the last piece of the hard part of my website so I'd be so grateful if anyone knows how to fix this. -

Resolving names of all Django related models when exporting a table to a text file (csv)
I have a simple Django (4.1/Python3.9) table with textual and numerical fields. In this table, four of these are ForeignKeys: 1 is referencing itself 1 is referencing an other table through a OneToMany relationship (aka simple ForeignKey) 2 are referencing 2 other tables through a ManyToMany relationship Django is kind enough, when using the model._meta.get_fields() method, to retrieve all related fields along with the usual fields of the model. And that's what I want. Within the admin page of that model, I can see all these related fields as "resolved", e.g. their name is displayed instead of their ids, this is because of the usual __str__(self) method we can use in the model classes: from django.db import models class Foo(models.Model): name = model.CharFields( max_length=100, unique=True, verbose_name="Foo name" ) # here are some other usual data fields self_relation = models.ForeignKey( "self", on_delete=models.CASCADE, null=True, blank=True ) bar = models.ForeignKey( "Bar", on_delete=models.CASCADE, null=True, blank=True ) baz = models.ManyToManyField(Baz) qux = models.ManyToManyField(Qux) def __str__(self): return self.name class Bar(models.Model): name = model.CharFields( max_length=100, unique=True, verbose_name="Bar name" ) # ... def __str__(self): return self.name class Baz(models.Model): name = model.CharFields( max_length=100, unique=True, verbose_name="Baz name" ) # ... def __str__(self): return self.name class Qux(models.Model): name = model.CharFields( max_length=100, …
