How to update web page after successfull ajax request without reload the page
I am sending the AJAX request to server and after success I would like to update the page without refreshing it fully. It is my snippet of code, but here I can just reloading the page and not sure how to do that without it, my line does not work either, could you help, please? PS. I am using Django for back-end function saveTags(slug, form, e) { e.preventDefault(); let tags = form.getElementsByClassName("new-tags")[0].value; if (tags != '') { var formData = { csrfmiddlewaretoken: '{{ csrf_token }}', slug: slug, tags: tags, }; var POST_URL = "{% url 'save_tags' %}"; $.ajax({ url: POST_URL, type: "POST", data: formData, success: function (data) { var x = document.getElementById("snackbar"); x.classList.add("show"); setTimeout(function(){ x.className = x.className.replace("show", ""); }, 3000); $("document").html(data); //window.location.reload(true); } }); // end ajax } return false; }; -
In Django, print a text in a textarea after clicking on a button
I would like to select an element of the combobox and print it in a textarea, after clicking on the button. I have no errors, but the problem that when I click the button nothing happens I have a combobox with this function: views.py def trips(request): country = request.GET.get('country') trips = Trip.objects.filter(country=country) return render(request, 'trips.html', {"trips": trips}) I would like to print trips in a textarea. So I created the textarea and the button (I DON'T want them in a form) home.html .... .... .... {% include "trips.html" %} <!-- Textarea--> {% include "result.html" %} <!-- NOTE: textarea name="result" id="id_result"></textarea>--> <!-- Button--> <button type="button" class="mybtn" href="{% url 'test'%}">Button 1</button> <button type="submit" name='mybtn' value={{test}}>Button 2</button> In views.py I also added the function to print in the textarea (but surely I must have done something wrong) def test(request, trips): new = ("my trips is ", trips) return render(request,"result.html", {"new": new}) In urls.py urlpatterns = [ path('trips', views.trips, name='trips'), path('mytest', views.test, name='test'), ] -
Django Python : This variable is defined, yet the shell says it is undefined not allowing me to process the page
Hi I'm relatively new to Django and am struggling to understand how models work with views. This is from a form used to create a flashcard. I'm trying to assign the characters inputted in the fields to the classes parameters. Then I would like to display the parameters in a card which I do in the template. Whilst I would like this issue fixed I would also be open to see if there are any better and more efficient ways to approach this issue. This is the section of my views.py that raise the issue: def flashcard(response): if response.method == "POST": form = Flashcard_verif(response.POST) if form.is_valid(): print("is workinggg boii") head = form.cleaned_data["header"] ques = form.cleaned_data["question"] ans = form.cleaned_data["answer"] flashcard_data = Flashcard(header=head, question=ques, answer=ans) global rawHeader, rawQuestion, rawAnswer rawHeader, rawQuestion, rawAnswer = Flashcard(header=head, question=ques, answer=ans).flash_format() print(rawHeader, rawQuestion, rawAnswer) flashcard_data.save() else: form = Flashcard_verif() return render(response, "main/Flashcard.html", { "form":form, "header":rawHeader, "question":rawQuestion, "ans":rawAnswer, }) This is the flashcard model: class Flashcard(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="flashcard", null=True) header = models.CharField(max_length=40) question = models.CharField(max_length=200) answer = models.CharField(max_length=200) def __str__(self): return self.header def flash_format(self): print(self.header, self.question, self.answer) return self.header, self.question, self.answer This is the template: {% extends 'main/base.html' %} {% load static %} {% block … -

Django: Hide required field in form and generate value from other fields
Having a class like this: class MyClass(): foo = CharField('Foo', max_length=42) bar = CharField('Bar', max_length=42) baz = CharField('Baz', max_length=42) Fields "foo" and "bar" should be show in the form, field "baz" should NOT be shown. When POST'ing, the field "baz" should be generated from "foo" and "bar", e.g.: baz = foo + bar The "baz" field can be prevented from shown in the form by using the "HiddenInput" widget. Ok. But using the CBV: Where to generate the "baz" content from "foo" and "bar"? In the "def post()", in the "def is_valid()", in the "def clean()"? Or somewhere else? -

django and stripe subscription payments issues
I'm trying to create a subscription based saas in django. There are three subscription tiers with both monthly and annual payment options.

How can I query my API in React in a way that has dynamically defined queries?
I'm using Django Rest Framework and React, but this is more of a conceptual question. I've noticed that when querying data from an API, especially on a React-esque frontend, I always run into the same issues. API responses are not intrinsically typed I cannot specific exactly what fields I'd like to get back from the API I can't specify dynamic type-safe filtering and sorting. In an ideal world, I'd like to be able to do something like this: // Using a user model as an example. export function UserComponent(props: ...){ // `data` is inferred to be of type Pick<User, "email", "lastActive"> const data = myCustomAPIFetch<User>({ model: User fields: [User.email, User.lastActive], filters: { [User.firstName]: "Linus" } // Similar syntax for sorting }) return (...) } This solves all three issues - it returns the proper type object, filtering/sorting is type-safe, and the exact fields that I want back can be specified. The solutions that I've researched here solve some of the problems, but not all. Graphql - solves #2 and can solve #1, but from what I understand I have to make a new query/resolver for each filter or sort I want to do. Not ideal. Protobuf - types are cross-language … -

I want to implement a feature where the coupon code can be reused if the order is cancelled. I prefer not to delete the objects so I can track the data. -
Save file (not in MEDIA_ROOT) to Django FileField from fastapi UploadFile
I need to save a fastapi UploadFile object directly to a Django model defined below: class MyFile(models): file = models.FileField(upload_to="files/") In the API, I managed to obtain file object from the SpooledTemporaryFile using the read and write methods like in the block below: async def file_upload(file: UploadFile = File(...)): async with aiofiles.open(f"path/{file.filename}", "wb") as media: cont = await file.read() await media.write(cont) Then I try to convert the new file to FieldFile type in Django to be able to save it in the MyFile.file field but it kept returning a TypeError with the description: write() argument must be str, not generator from django.core.files import File as DjangoFile async def file_upload(file: UploadFile = File(...)): ... async with aiofiles.open(f"path/{file.filename}") as media: d_file = DjangoFile(media) file_model = MyFile() file_model.file.save(file.filename, d_file) file_model.save() return {"ok": True} The stack trace revealed file_model.file.save(file.filename, d_file) as the offending line. >>> type(file.filename) str >>> type(d_file) <class 'django.core.files.base.File'> Could you point me in the right direction? Thanks. -
Running django test, migrations with django.conf import settings are not using DJANGO_SETTINGS_MODULE or --settings override settings
I have a migration which does a check on settings.DEBUG, I've imported settings using from django.conf import settings and if it's False I'm expecting that this is a production(or production-ish) environment so I'm importing a secrets manager secret to use in a createsuperuser migration function, otherwise it's local hosting or local dev and I'm just using a hard coded string. My problem is that in my settings.py I've set DEBUG to false as a safe default, similar to how I set my SECRET_KEY to None so that if for some reason the settings override fails I get an error not the generated SECRET_KEY. Anyway, back from that aside, I'm trying to run ./manage.py test --settings=myproject.test (I have also tried using an export of DJANGO_SETTINGS_MODULE='myproject.test') to load my test.py settings file, at the top of which it does a from .settings import * import and then further down the page I overwrite the setting with DEBUG = True. So in my migration I from django.conf import settings and I'm expecting that to load my DJANGO_SETTINGS_MODULE settings, when I run my tests and it runs my migrations, I'm expecting that from django.conf import settings is going to use my DJANGO_SETTINGS_MODULE settings I …
