Issue with accessing form.cleaned_data in Django view function
I'm encountering an unexpected issue while working on a Django project involving a registration form. I have two code snippets that are functionally similar, but I'm getting different outcomes regarding the access to form.cleaned_data. I'm hoping someone can help me figure out what might be causing this discrepancy. Code Snippet 1: def signup(req): if req.method == 'POST': form = RegisterForm(req.POST) if form.is_valid(): messages.success(req, 'Account Created successfully') form.save() print(form.cleaned_data) return render(req, 'signup.html', {'form': form}) else: form = RegisterForm() return render(req, 'signup.html', {'form': form}) Code Snippet 2: def signup(req): if req.method == 'POST': form = RegisterForm(req.POST) if form.is_valid(): messages.success(req, 'Account Created successfully') form.save() print(form.cleaned_data) return render(req, 'signup.html', {'form': form}) form = RegisterForm() return render(req, 'signup.html', {'form': form}) In both snippets, the form is submitted and processed similarly. However, when I use the first snippet, I can successfully access form.cleaned_data and print it after a successful form submission. But when I use the second snippet, form.cleaned_data seems to be unavailable, and the printed output is empty. I have double-checked the code for any typos or missed details, but both snippets are practically identical. I'm quite puzzled as to why this difference in behavior is occurring. -

Why in Django many-to-many relation shows wrong data in the admin panel
I'm trying to implement the many-to-many relation to support in the user model these features: user followers (persons who follows the user) user following (persons the user follows) To achieve that I'm using double relation on the same model because followers/following are the same User models. Basically it works hoverwer I'm facing a weird behavior in the Django admin panel. When I add some user to other user to the following list (in the shell everything ok), the Django admin panel shows that user in the followers list but he should be in the following list. I can't understand why it happens. Many thanks for any help! My models.py from django.contrib.auth.models import AbstractUser from django.db import models class User(AbstractUser): followers = models.ManyToManyField('self',blank=True,related_name='user_followers',symmetrical=False) following = models.ManyToManyField('self',blank=True,related_name='user_following',symmetrical=False) pass Supppose Admin wants to follow Neo. Neo should have follower - Admin. Admin - should have Neo in his following list.

Django on_delete for Model with custom delete function
I have the following models: class Concert(models.Model): name = models.CharField(max_length=255) is_deleted = models.BoolField(default=False) def delete(self): self.is_deleted = True self.save() class Ticket(models.Model): concert = models.ForeignKey(Concert, on_delete=models.CASCADE) is_deleted = models.BoolField(default=False) def delete(self): self.is_deleted = True self.save() I noticed when I call delete on Concert, it doesn't call delete on Ticket. This is expected behavior, right? Is there any way to trigger CASCADE even in the case of this custom delete function? -
Google Ads API & Python - How to get all accounts (name + ID) that a user has access
I'm trying to get the account name and ID of all the accounts that the logged user has access to. I've managed to get the IDs using the code on https://developers.google.com/google-ads/api/docs/account-management/listing-accounts?hl=es-419. But I need the names too and apparently you have to make one API call for each ID to get their account names or any other info. I've tried with the following Python (Django) code, but it's not working (it probably could be improved a lot and maybe has mistakes, I'm a Python beginner): def one(request): client = credenciales(request) ga_service = client.get_service("GoogleAdsService") # Get customer resource names from the original code customer_service = client.get_service("CustomerService") accessible_customers = customer_service.list_accessible_customers() customer_resource_names = accessible_customers.resource_names # Prepare a list to store customer data list_clients = [] # Iterate through each customer resource name for resource_name in customer_resource_names: # Extract the customer ID from the resource name custom_id = resource_name.split('/')[-1] # Create a query using the customer_id query = f''' SELECT customer_client.descriptive_name, customer_client.id, customer_client.status FROM customer_client ''' stream = ga_service.search_stream(customer_id=custom_id, query=query) for batch in stream: for row in batch.results: data_clients = {} data_clients["descriptive_name"] = row.customer_client.descriptive_name data_clients["id"] = row.customer_client.id data_clients["status"] = row.customer_client.status list_clients.append(data_clients) # Pass the list of customer data to the template context = { … -
django object.id does not work when passed in an url in html
I have just started learning Django and I cannot figure out why my player.id kills the page when I try to pass it in an url, while it does work as a variable (see both in the code below.) When I omit the player.id from the url, the page works (except for the "delete" link, of course). {% for player in all_players%} <li>{{player.player_name|capfirst}} scored {{player.player_score}} and the id {{player.id}}!</li> <div class="link" id="link"> <a href="{% url 'delete' player.id %}"> delete </a></div> {% endfor %} Here is my urls and "delete" in view: urlpatterns = [ path('first', views.first, name='first'), path('delete/int:player_id', views.delete, name='delete'), path('third', views.third, name='third'), path('second/int:player_id', views.second, name='second'), path('', views.index, name='index'), ] def delete(request, player_id): player = Player.players_objects.get(id=player_id) player.delete() return render(request, 'all_players.html', {'player': player}) -

Is there a way to make a https post with only port 80 in nginx config file?
So, I a have Django app which needs to send data to an API. I am using request to send the data. First, it was warning me that -in short- I am not using SSL for sending the JSON data. To solve this I added "verify=PATH TO THE CERT FILE" requests.post(url, json=payload, verify='\fullChainCert.crt') After this I got 200, so I was happy. Question is, will it work like this on server? Port 443 is open on server, but only 80 in nginx config file. -

Moving from Django signals to save override: How to translate the "created" parameter of a Django post_save signal for a save method override
I have made some bad decisions earlier regarding how I handle post_save events on a Django model and I am currently looking into changing my approach. Let's begin by making my example. Here is my model. class MyModel(models.Model): #... all my model creation and logic are here def do_something(self): # Actually do something, for the sake of simplifying the example, just write pass pass Now, what I am using is a receiver function like this one. It works, but for many reasons that are mine, I want to stop using signal in this case. @receiver(post_save, sender=MyModel) def foo(sender, instance, created, **kwargs): if created: instance.do_something() I imagine I could override the MyModel.save method, something like this: class MyModel(models.Model): #... def save(self): super().save() if created: # It is this line that I need to figure how to do. self.do_something() By what should I replace the if created: of my receiver function if I want to override the save() method? Or do you have something else to recommend? I would also be curious if it is the same thing for pre_save signals. -

Subtract datetimes, round result to full hour python
I am trying to calculate time between one date and another and give result in hours rounding up hours. I tried just substracting, both dates are datetime total_hours = self.valid_until - self.started_at the result is timedelta. I tried this one but it seems like it is viable for datetime field only (total_hours.replace(second=0, microsecond=0, minute=0, hour=total_hours.hour) +timedelta(hours=total_hours.minute//30)) -
After pushing my code from the production server to a gitlab repository, I have a problem with postgresql and migrations in my django webapp
Now maybe I'm getting this wrong but here's my story : Today, i decide to get the code that I've been writing in an uncontrolled manner on the production server to a gitlab repository.

Trying to send Validation Email in django, getting error
Im trying to send validation email when creating a user in django. It used to work like that but then I did some refactoring on the URLs and used urlpattern = UrlPattern() and urlpattern.register(UserView). That is in the main django project url.py In the app url.py Im having urlpatterns = [ path('activate/<uidb64>/<token>', backend_logic.activate, name='activate') ] where activate is a function in backend_logic, which used to work and send the email to the one from request. However, now Im getting the error Reverse for 'activate' not found. 'activate' is not a valid view function or pattern name. -

Any way to use CRUD TableBlock in Wagtail?
I'm talking about a table with data from a model (like Django). So that the visitor can make changes to the table fields without reloading the page. The description of the framework shows several options for developing such a solution in WAGTAIL make a snippet and link it to a table. There will be a filter option. But I still could not understand whether it is possible to make changes to the table cells without reloading. In that case, I suppose to use something like that: @register_snippet class Mapping(models.Model): map_code = models.OneToOneField('Map', models.DO_NOTHING, db_column='curr_map_code', primary_key=True) date_begin = models.DateField() class Meta: managed = True db_table = 'MAPPING' Using the STREAMFIELD add a TABLEBLOCK. the documentation says that it is based on handsontable 6.2.2 and it has the ability to make changes without rebooting page with table. But I cant achive managed to generate table data based on the Django model and possibility for user edit. That is, I can manually enter values in the cells in the admin panel. But in the custom view, there is no such possibility at all. Try to use something like that: class Mapping(models.Model): map_code = models.OneToOneField('Map', models.DO_NOTHING, db_column='curr_map_code', primary_key=True) date_begin = models.DateField() class Meta: managed … -
I need a brief explanation into how to connect my Django application to a Google Cloud MySQL database
I'm pretty new to web development and I'm currently deploying my first web application. It's pretty much built with stock Django and a few dependencies. Right now, I have it deployed on Railway.app with a very standard SQLite database. However, I would like to have my data stored in a more long term solution, so I'm looking at using MySQL inside of a Google Cloud instance. I have already tested my application using a local mySQL database, now, I'm trying to connect it to the remote one. However, I'm a bit stumped in how to do it on the Google Cloud instance. Google Cloud provides me an public IP, I have an user and password and a database created there, but that is not enough and I'd like some guidance in how to proceed from here. From what I understand, Google Cloud requires the user to access through an allowed network and I'm unsure what that means. I'm also unsure what this would look like once deployed on Railway. Google Cloud in general uses a lot of names that I don't quite understand. Do I need to use a Cloud Console to do anything? Is there anyway for me to … -

Use Django Allauth with inertia.js & Vue
I'm trying to using Django Allauth with inertia + vue combination. Take a view like e.g.: from inertia import render def about(request): return render(request, "About", props={"pageName": "About"}) I have my project configured in a way that it will render this inside About.vue like so: <script setup lang="ts"> defineProps<{ pageName: string; }>(); </script> <template> <div> <h1>This is the {{ pageName }} page</h1> </div> </template> How would I go about connecting this to Django Allauth? Thinking of something like extending from e.g. their LoginView: from inertia import render from allauth.account.views import LoginView def login(request): return render(request, "Login", props={"context_obj": ?}) Not sure what I can do to pass the context object through. Anyone any ideas? -
Migrate from CharField to LocalizedCharField
I am integrating django-localized-fields and have to save current data in char field at least in default language. For example: from django.db import models class FineModel(models.Model): title = models.CharField(max_length=128) needs to migrate to from localized_fields.models import LocalizedModel from localized_fields.fields import LocalizedCharField class FineModel(LocalizedModel): title = LocalizedCharField(blank=True, null=True, required=False) and text from title column should be transferred to updated title column like that: new_obj.title.en = old_obj.title I tried to add new temporary field title_l and use 3 migrations to transfer all data from title field to title_l field delete title field rename title_l to title and delete title_l from model but this is not working, because first of these migrations will fail on production contour because title_l is not presented in FineModel. Any advices appreciated, I believe this can be done in single migration. -
