validators for bulk image upload
I have setup a validator for a image upload field to check if the image is too large, it is working as expected. def validate_image(image): file_size = image.file.size if file_size > settings.MAX_UPLOAD_SIZE: raise ValidationError(f'Image {image} is too large 3mb max') image = models.ImageField(default='default.jpg', storage=PublicMediaStorage(), upload_to=path_and_rename, validators=[validate_image]) Now I want to do the same thing for a bulk image upload field I have. def validate_image_bulk(images): file_size = images.file.size if file_size > settings.MAX_UPLOAD_SIZE: raise ValidationError(f'Image {images} is too large 3mb max') images = models.ImageField(upload_to=path_and_rename_bulk, validators=[validate_image]) If you upload more than one image and one of the images is above the max upload threshold it does not upload any of the images and does not throw the validation error but it still submits the form. If you upload a single image that is too large the same thing occures How can I raise the validation error and not have the form submit like it does for the single image field view: (the bulk model is PostImagesForm) postForm = PostForm() if request.method == 'POST': postForm = PostForm(request.POST, request.FILES) if len(request.FILES.getlist('images')) > 30: raise Exception("Max of 30 images allowed") else: if postForm.is_valid(): PostFormID = postForm.save(commit=False) PostFormID.author = request.user PostFormID.save() if len(request.FILES.getlist('images')) == 0: return redirect('post-detail', … -

Djanog display user specific objects
I solved the last problem. Now I tested some stuff and got a problem. I want to display user specific objects. If user a user enters his details (for example number), I just want to display the phone number of the user in the html template, not from someone else. So the user can only see his number. I created this. forms.html <form method='POST' action="." enctype="multipart/form-data"> {% csrf_token %} {{ form }} <button type='submit' class=''>Submit</button> </form> <p>{% if details.phone %} {{details.phone}} {% else %} &nbsp; {% endif %} </p> <p> {{ request.user }} </p> views.py def edit_profile(request): details = UserProfile.objects.all()[0] try: profile = request.user.userprofile except UserProfile.DoesNotExist: profile = UserProfile(user=request.user) if request.method == 'POST': form = UserProfileForm(request.POST, instance=profile) if form.is_valid(): form.save() return redirect('/') else: form = UserProfileForm(instance=profile) return render(request, 'forms.html', {'form': form, 'details': details}) models.py class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.TextField(blank=True) phone = models.CharField(max_length=10, blank=True) address = models.CharField(max_length=1024) age = models.PositiveIntegerField(blank=True, null=True) gender = models.IntegerField(default=1) The {{ request.user }} works fine, it shows the current username of the signed in user.

How can I use a url parameter(that is a user id <str:pk>) to prepopulate a field in DJANGO form
I'm doing a management application with 2 pages: users(clientes) and a user datail page that contains a user payment history(cheques). I'm trying to do a create a form in payment history page(cheques.html) to add a new payment, but I'd the Cheque.cliente would be equals to the current user URL. Ex.: if your URL is cheque/5/, the Cheque.cliente should be 5, and when I add a new payment, the payment should be tracked(ForeignKey) to the user 5(each user has many payments). Resuming: This application has the functions to CRUD all the user(clientes) and all the payments(cheques), but only the add payment(cheque) function isn't working.

Django Password Reset Email sending incorrect link
I am using the auth_views login and password reset system for the accounts app in a Django project. The password reset functionality works fine on the localhost. However once deployed when trying to reset the password the email that is sent to the user's registered email account contains the incorrect reset URL. The domain part of the reset URL contains the localhost address and not the domain of the site. The email is sent to a link like http://127.0.0.1:8000/accounts/reset/MTk/azifmz-484db716de96c7628427b41e587c1910/[![enter image description here]1]1 What I am expecting is for the sent email to contain the correct return URL specific to the domain that is sending it. e.g https://www.example.com/accounts/reset/MTk/azifmz-484db716de96c7628427b41e587c1910. In settings.py LOGIN_REDIRECT_URL = '/' LOGOUT_REDIRECT_URL = 'index' STATIC_URL = '/static/' STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')] SOCIALACCOUNT_PROVIDERS = { 'google': { 'SCOPE': [ 'profile', 'email', ], 'AUTH_PARAMS': { 'access_type': 'online', } } } EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend" EMAIL_HOST= 'smtp.gmail.com' EMAIL_HOST_USER= 'myemail@gmail.com' EMAIL_HOST_PASSWORD= 'mypassword' EMAIL_USE_TLS= True EMAIL_PORT= 587 In my accounts urls.py I am using the default classed bassed views provided by django.contrib.auth. There are no custom views for the reset workflow. I am hoping to configure this workflow to avoid having to write custom views for now. urls.py path('password_reset/', auth_views.PasswordResetView.as_view( template_name="accounts/password_reset_form.html", success_url="done/"), name="password_reset"), path('password_reset/done/', auth_views.PasswordResetDoneView.as_view( … -
Django-Admin Reload Inline based on parent Field
I have simple scenario with a Account class and a AccountDetail class. The AccountDetail is a inline: class AccountDetailInLine(admin.TabularInline): model = AccountDetail @admin.register(Account ) class Account Admin(admin.ModelAdmin): inlines = [AccountDetailInLine] The problem is that I can't have multiples records for the same account on same date. So when the user is adding a new Account, if he chooses a previously created Account and date, the inline should reload the table with elements he created before to continue filling the records. Sorry if it's not clear. How could I do this? The flow is: User adds a new Account with name and date and the details in Inline User Saves User go to Add again and choose a date that was previously saved The tool should fill the Inline with the previously added to this date so he can to continue filling the data. <---- Here's my doubt -
How can I save a django form
So I want to save a Biographie for each new created User. The user can enter his Bio and it will the it to his Profile. For this I created a model with OneToOneField from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver class Profile(models.Model): user = models.OneToOneField( User, on_delete=models.CASCADE, null=True, blank=True) bio = models.CharField(max_length=30) To create the form I did the following in forms.py: class BioForm(forms.ModelForm): class Meta: model = Profile fields = ('bio',) Then I created in the views.py the saving, so the bio will be saved to the specific user: from .forms import LoginForm, RegisterForm from django.shortcuts import render, redirect from django.contrib.auth import authenticate, login, logout, get_user_model from django.contrib.auth import get_user_model def test_view(request): form = BioForm(request.POST) user = get_user_model if form.is_valid(): profile = form.save(commit=False) profile.user = request.user profile.phone_number = request.phone_number profile.save() return render(request, 'test.html', {'form': form}) There is something big wrong in the views.py but I don't get it. I can submit the form and the form will be saved (sometimes) but without the user who wrote it + I get this error: ValueError at /test/ Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x00000253B7140D00>>": "Profile.user" must be a "User" instance -

Solutions for tracking time user spent on a context
I working on case management system. We have operation staffs working on filling out/processing data for a case. The system is built using React on frontend and Django on backend. The URL for a single case is like this pattern: /case//< action name> I'm looking for a solution (open source or commercial) to track user activities and eventually calculate how much time a user spends on a case, e.g: how much time in total operation staffs spend on a specific case, and how much time on average operation staffs spend on a single case, etc. Right now I'm looking into Real User Monitoring(RUM) solutions like Datadog RUM. The data structure can be used to achieve what I want but the challenge is there is no way to extract those raw data or stream it to another database to do further calculations. Am I going in the right direction? Really appreciate any suggestion. -
What's the pros and cons of having a model for each Product Attribute?
I have a two generic models in my app: ProductAttributes and ProductAttributesValue (besides Product and ProductCategory, which are not relevant for this discussion). These two models contain respectively all the different attributes and their values. For example, "brand" as an Attribute, and "nike" and "addidas" as its Attribute Values. I'm running into an issue with this setup, though, as I want to create a page for each brand. I think this would be easier, if brands did not share model with other attributes, like color, size etc., which I do not want to create unique pages for. There may also be other scenarios. In general, what's the pros and cons of having a unique model for each Product Attribute, versus having a shared model? Note: I want to still be able to have long URLs that contain one category and several attribute values, like domain.com/shoes/red/nike -
