Trying to update user email using Djoser set_username
I am trying to update my user's username. For some reason when I call /users/set_username it says that: {"current_password":["This field is required."],"new_email":["This field is required."]} So I edited my code to follow that. export const updateUserEmail = (email, password) => dispatch => { const data = { "new_email" : email, "current_password" : password } axios.post("/api/v1/users/set_username/", data) .then(response => { const user = localStorage.getItem('user') let username = JSON.parse(user).username const newUser = { "username": username, "email":email } localStorage.setItem("user", JSON.stringify(newUser)); dispatch({ type: SET_CURRENT_USER, // auth store payload: user }); // dispatch(push("/")); toast.success("Update Successful."); }).catch(error => { // show error toast console.log(error) toastOnError(error); }) } But every time I run this I get a 500 internal server error, but I'm not sure why. I have tried removing the last slash, but that didn't work. I am expecting to update the user's email. -
How to pass an additional parameter to a field on a model that is pointed to by a foreign key in Django?

And file field in File model can get allow_extensions. How do I implement this feature? -
Race condition in Django save()
I have an API that can take a list of files and save it in the DB for a specific user. I want to limit the number of files per user to be some number. The way I enforce this is through overriding the save method: A pseudocode: In the view: For item in list_to_save: item.save() And save method: curr_count= Files.objects.filter(id=user_id).count If curr_count > max_count: Get curr_count-max_count item For del in delete: del.delete() Question is, will this lead to a race condition if the same user tries to send 2 different list of files? Since there might be 2 save operation running at the same time? I am expecting that there is some race condition since the two server will see that DB has entries, and will try to delete them both, leading to some inconsitencies -
django: Recursive function called in views.py method not returning results
I am new to django and web development, I am trying to call a recursive function in views.py on clicking submit button on my form. When I try to call the same function while it returns a simple list, it works fine, but it returns nothing if the core logic is enabled. I am really not sure what's the problem, can anyone tell what's wrong and how to fix it? Following is the implementation of views.py and recursive function: def process_form(request): if request.method == 'POST': print("Request is POST") form = UIForm(request.POST, request.FILES) if form.is_valid(): print("Form is valid") # Create an instance of the model and assign the form data to its fields form_data = FormData() form_data.from_timestamp = form.cleaned_data['from_timestamp'] form_data.to_timestamp = form.cleaned_data['to_timestamp'] form_data.free_text = form.cleaned_data['free_text'] form_data.uploaded_file = form.cleaned_data['file'] # Save the form data to the database form_data.save() file = request.FILES['file'] todayDate = datetime.datetime.now().strftime("%Y-%m-%d") dest_dir = temp_directory + os.sep + todayDate dest_path = dest_dir + os.sep + file.name os.makedirs(dest_dir, exist_ok=True) print("Dest path:", dest_path) # Handle the uploaded file if file: # Save the file to the server's temporary directory with open(f'{dest_path}', 'wb') as destination: for chunk in file.chunks(): destination.write(chunk) # Check the given regular expression against the extracted files pattern = form_data.free_text … -
Make my web page offer download of zipfile
I am building an archive where people can download zip-files (the url is localhost:8000/downloads). I have the zip-files in the games folder (in relation to where manage.py resides). When I pass over with cursor the address shows "localhost:8000/downloads/.../games/GC_007 Goldeneye.zip" which gives "no download" This is what I put in the link: <a href="games/GC_007 Goldeneye.zip" download>007 Goldeneye</a> "localhost:8000/downloads/.../games/GC_007 Goldeneye.zip" is what I get which does not work. -
Like icon and Likes counter does not refresh automatically
I am trying to get a Web page that updates the Likes counter when a user clicks on the Likes icon (similar to Twitter, now X): I am using JavaScript and Django (I am a newbie in both). I am facing this issue: when I click on Like icon ("thumbs up" by default) the Like counter increase but the Like icon does not change to a "thumbs down" icon and indeed if I click on Like icon again then the Like counter increase again. Once I refresh the page manually the Like icon appears as thumb down. I would like that: when I click on Like icon ("thumbs up" by default) the Like counter increase and the Like icon changes to a "thumbs down" icon when I click again on Like icon (it is a "thumb down" icon now) then the Like counter decrease and the Like icon changes to a "thumbs up" icon the above should be gotten without requiring a reload of the entire page (I have to refresh the page manually right now) Please find below my code: index.html {% extends "network/layout.html" %} {% block body %} <!-- Javascript code --> <script> function getCookie(name) { const value … -
Error with static CSS files while deploying django app to Heroku
I'm a new developer here, and I am trying to deploy my first web app (created using Django) and I am using Heroku. I have been getting errors with my static files and while trying to troubleshoot that I've created a few other errors and I am hitting a wall with troubleshooting the errors. Can anyone take a look at the Heroku build log and VSCode and tell me if they see anything? I am trying to deploy my web app using Heroku. My website works fine locally but won't finish deploying. Im getting errors in the static files. I think it might have something to do with the static path.

HTTP/1.1" 405 0 Django - Unable to go past Login Page
I created a login page and I have users with 3 roles, Administrator, Student, Supervisor. Each of these users have their separate dashboards. When I login using the username and password, it should check the user's group and based on which should redirect the user to their respective dashboard. When I hit the submit button to login, it gives me an error `.

EmailAddress model in Django allauth?
I just started using Django allauth, and I noticed that it created a new accounts_emailaddresses table. I understand this is useful for email confirmation, but if feels like this is a source of denormalization in our database. Our current User model already has an email field. It seems like now I have to maintain the state of both User and allauth.EmailAddress models now. For example, when a user changes emails, I need to change the User model and also mark the new email as primary in EmailAddress This seems really annoying...what is the best practice in this case? Should I remove email field from User? I'm wondering how most people handle this. -
Django 'python manage.py runserver' has stopped working. How can I fix this?
I'm attempting to use Django to create a website builder. I have created a development webserver with "python manage.py runserver" and it worked initially. I created a Products app and added code in the views module and the url module under this app, whilst also mapping it to the parent url module using "path('products/', include('products.urls'))" but when I go back to the link produced by the server, it no longer works. I don't know what the problem is and how to fix it, as I didn't do anything different from the first time I tried this, and it worked briefly, before it stopped. I had to start a new project when this happened but I don't have time to keep starting over. This worked a few days ago but the next day the runserver command wasn't working. I had to delete the project and start again and now I am running into the same problem and I don't know what to do -
Django Related Model Calculations
I am creating a dashboard of sorts, I have two related models. Models: class Batch(models.Model): ... batchid = models.AutoField(primary_key=True, serialize=False, auto_created=True) batchsku = models.CharField(max_length=96) productionarea = models.CharField(max_length=96, choices=prod_area_choices, default=PRESS, verbose_name="Production Area") batchlbs = models.DecimalField(max_digits=15, decimal_places=3, blank=True, null=True, verbose_name="Lbs/Batch") batchcases = models.DecimalField(max_digits=15, decimal_places=4, blank=True, null=True, verbose_name="Cases/Batch") def __str__(self): return self.batchsku class BatchProduced(models.Model): ... batchprodid = models.AutoField(primary_key=True, serialize=False, auto_created=True) sku = models.ForeignKey(Batch, related_name="batch_exists", on_delete=models.PROTECT) location = models.CharField(max_length=96, choices=batch_prod_area_choices, default=PRESS1) created_by = models.ForeignKey(User, on_delete=models.PROTECT) created_time = models.DateTimeField(auto_now_add=True) def __str__(self): return self.sku For the view I would like to see some specific filtered information from the above models. Specifically I would like to have a count, which I get as part of my view through: pr1batchcount = BatchProduced.objects.filter(created_time__date=today, location='pr1').count() In the same view I would like to be able to calculate pr1batchcount * Batch.batchcases but I am struggling to figure out the best approach. I thought about a model calculation under the BatchProduced model like def expcases(self): return sum([Batch.batchcases for Batch in self.item_set.all()]) But this is failing to return anything, and I am not quite sure I am even pointing the right way. I am not confident in my Django knowledge to know if this is the right approach, I've gone through all related … -
How can I set a "safe" running "mode" that determines the collective behavior of django model superclasses I created?
Sorry for the poorly worded title. I just don't know how to phrase it succinctly, but I think I can best ask my question by example. Here is the background: I have a working Django model superclass I wrote called MaintainedModel. It provides a way to auto-update selected fields in a model class using decorated methods that the developer implements in the derived model class. The execution of those methods is controlled automatically via various overrides in my MaintainedModel superclass, such as an override of the Model.save() method. If a model object ever changes, the "maintained fields" in the derived model are auto-updated. It also provides a means to trigger those updates via changes to related model objects such that updates propagate via a relationship chain. One problem I had to overcome is that the autoupdate methods can sometimes be complex and take some time, especially if there are multiple triggers of the same model object due to multiple triggering related model changes. In the wild, that extra time is not noticeable and you don't encounter this repeated trigger case, but during a load of a mass quantity of data, it can double or triple the load time. I worked … -

Why is my Django view not recieving input from my HTML form?
I am making a website that takes user text, modifies it and returns a response using Ajax. I am using Django on the backend and vanilla JS on the frontend. The user chooses source_language and target_language, enters some text in input_text and the browser outputs a translation in the output_text textarea. However whenever I try I keep getting either a None as output_text(as the output from my translation API) or a No Null error for input text whenever it tries to save to the database, so it seems the input text is not being detected by my django view. The same goes for the source language and target language. When I comment out the code to save translation to the database I get None as ouput text. However when I check the payload (in developer tools) being sent I see the input text and the selected languages. I use the <form> tag in my HTML with AJAX so as to prevent page reloads when the user recieves a response. When I remove all JS it works as expected but of course the presenation is a black screen and requires a page reload. Here is my code: JS: const csrfToken = … -
Django field with foreignKey
I'm using Django v4.1 and have a foreignKey relationship I want to pull into a form. The two models: class Service(models.Model): client = models.ForeignKey("Client", on_delete=models.SET_NULL, null=True) # some other fields and class Client(models.Model): name = models.CharField(max_length=50) # a few more fields The form: class ServiceForm(forms.ModelForm): class Meta: model = Service fields = "__all__" However, in the front-facing form, "Client" is generated, but without a SELECT field. There is another model with a foreignKey relationship to Client, order: class Order(models.Model): client = models.ForeignKey("Client", on_delete=models.SET_NULL, null=True) # more fields... And it's form: class OrderModelForm(forms.ModelForm): class Meta: model = Order fields = "__all__" Which renders as expected with a SELECT field for the Client. Looking at the forms docs I experimented with (importing Client from models and) adding a ModelChoiceField, ("client": forms.ModelChoiceField(queryset=Client.objects.all()) both inside and outside of a widgets dict), but based on this SO post I'm thinking Django should be rendering that on it's own, as it is for Order. Please share suggestions in debugging. Thanks much. -

Prefetching related objects for templates
I have two models, Signup and Report, related via a third model, Training: class Signup(models.Model): pilot = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="signups" ) training = models.ForeignKey( Training, on_delete=models.CASCADE, related_name="signups" ) class Report(models.Model): training = models.OneToOneField( "trainings.Training", on_delete=models.CASCADE, primary_key=True ) And e.g. in the update view for a Report I try to prefetch the Signups and their Pilots and sort them into the context: class ReportUpdateView(generic.UpdateView): model = Report def get_object(self): training = get_object_or_404(Training, date=self.kwargs["date"]) report = get_object_or_404( Report.objects.select_related("training") .prefetch_related("training__signups__pilot") training=training, ) return report def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) ... runs_by_signup = {} for signup in self.object.training.selected_signups: runs_by_signup[signup] = [...] context["runs_by_signup"] = runs_by_signup return context and in the corresponding template I call signup.pilot like so: {% for signup, runs in runs_by_signup.items %} <tr> <td class="text-nowrap">{{ signup.pilot }} ... </td> </tr> {% endfor %} However, each signup.pilot results in a call to the database to figure out the corresponding pilot. Is there a way to avoid these extra calls or do I have to store all information in get_context_data? -
Django IntegrityError in Admin Panel for Custom User Model

So those files are being displayed on the page, and this is also working fine. So the problem is very about the downloading part.The page that is displaying the files name as links This is the function that is rendering the page and that is returning a list with all the files in a directory.

JavaScript async/await polling to get a status - function doesn't return the correct data
Context: asynchronous tasks management in Django with Celery and Redis. I have a function that sends a POST request in Ajax. The server returns a task id. With the task id I launch another function just after the POST request to fetch the task status in order to check if the worker has executed the task successfully. Problem: I succeed in doing the polling with javascript and log the results. But at the end my function doesn't returns the correct data (the one in the if statement). It's as if the object returned by the if statement is ignored. It's the first time I write such a function.

Django form.is_valid() results in False, Not sure what is the cause
I'm currently doing CS50w,in project 1 it's assign to create a sort of wikipedia like site, user should be able to create new entries for that wiki and edit existing ones, this is where I got stuck.

Getting id error in one of my views in django
I'm getting an error: TypeError: edit_book() got an unexpected keyword argument 'book_id' Exception Location: /...env/lib/python3.10/site-packages/django/contrib/auth/decorators.py, line 23, in _wrapper_view view: from .forms import BookForm @user_passes_test(user_in_book_store_staff_group) def add_book(request): if request.method == "POST": form = BookForm(request.POST, request.FILES) if form.is_valid(): form.save() return redirect("books") else: form = BookForm() return render(request, "add_book.html", {"form": form}) url: path('edit_book/<int:book_id>/', views.edit_book, name='edit-book'), forms.py from django import forms from .models import Book, Author, Genre class BookForm(forms.ModelForm): class Meta: model = Book fields = '__all__' # Use all fields from the Book model widgets = { 'genre': forms.CheckboxSelectMultiple(), } I tried to set up a view without django form and also failed without decorator - same error. I'm VERY new to this, I'm jumping between youtube and chatGPT but I can't figure this one out, I'm not sure if I provided you with enough info.
