django - production/development migrations and databases mixed up
This is my first Django app deployment, a lot to learn. So this is my settings for DATABASES in settings.py if DEBUG: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } } else: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'db_name', 'USER': 'db_user', 'PASSWORD': 'db_password', 'HOST': 'localhost', 'PORT': '', } } Problem: For fixing a bug, I updated some fields in models locally, git push, and git pull on server, make migrations on server like I normally would locally; the migrations were successful, however, they don't seem to have applied (if it's of any relevance, the bug fixing was some phone number field changed from IntegerField to CharField, preventing the error "Verify that this value is less than or equal to 2147483647"; But the weird thing is there wasn't any error for the cellphone IntegerField before deployment and running locally) Confusion: I remember that only one superuser was created on postgres database, or at least I thought it was, but I can log in with this superuser account in both production and development (that is no matter the DEBUG is set to True or False), how is that possible?? Same are the images uploaded only once, but … -

Django Search Form Errors When Adding to_form_field
Whenever I try to add to_form_field to subject and membership form fields, I get the following errors: ValueError: invalid literal for int() with base 10: 'Programming' ValueError: invalid literal for int() with base 10: 'Free' Field 'id' expected a number but got 'Programming'. Field 'id' expected a number but got 'Free'. URL without to_form_name: http://127.0.0.1:8000/courses/?name=&min_views=&max_views=&min_date=&max_date=&expertise=&subject=1&membership=1 URL with to_form_name: http://127.0.0.1:8000/courses/?name=&min_views=&max_views=&min_date=&max_date=&expertise=&subject=Programming&membership=Free I would like to be able to pass the actual string rather than the number in the URL for SEO purposes. When I leave to_field_name out of forms.py, there is no error and my search form filtering works. But it puts numbers in the URL which is undesirable.

How to update extended user profile in Django with one-to-one link?
I am trying to figure out how to extend the User model using a One-to-One relationship in Django. I'm creating a user Profile to hold extra information about the User. However, I am new to Django and do not understand how I update this user Profile. I want to add a UserProfileSerializer to the serializers file to update the Profile, how do I do this? And how do I call this in my views file? The closest information I can find is: def update_profile(request, user_id): user = User.objects.get(pk=user_id) user.profile.bio = 'Lorem ipsum dolor sit amet, consectetur adipisicing elit...' user.save() However, I do not understand how I can reference the user_id through my serializer class, or how I can pass through user_id from a request. Below is the User model serializer and views, and the Profile model. The profile model class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) pin = models.CharField(null=True, max_length=4, blank=True) birth_date = models.DateField(null=True, blank=True) security_question_1 = models.CharField(null=True, max_length=100, blank=True) security_question_2 = models.CharField(null=True, max_length=100, blank=True) security_question_3 = models.CharField(null=True, max_length=100, blank=True) # post_save is the signal received when a save event occurs in the User model @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): … -

Overwrite Django model __init__ method
The Ingredient model of my Django project has an IntegerField which declares if this ingredient stock is managed by weight, units, or litters. Although the database has its integer value I have to display its name. And instead of looping over every ingredient and setting its value, I thought it was better to overwrite the __init__ method of the Python class, but I don't get how. models.py: class Ingredient(models.Model): def __init__(self): super(Ingredient, self).__init__() if self.cost_by == 1: self.cost_by = 'Units' elif self.cost_by == 2: self.cost_by = 'Kilograms' elif self.cost_by == 3: self.cost_by = 'Litters' #...etc... So far I tried with this, but I'm getting the following error: __init__() takes 1 positional argument but 0 were given Which argument should I pass? -
Yet another: URL resolves, but in a Django template URL NoReverseMatch(es)
I have a Python3.7, Django3.0 situation involving a URL that Exception Type: NoReverseMatch Exception Value: Reverse for 'create' not found. 'create' is not a valid view function or pattern name. Your assistance in this matter is appreciated. After reading a gobsmack of other questions similar to mine, I'm guessing there is a typo I just can't see. Maybe you can see it :D Many mahalos. library(app)/urls.py: from django.urls import path from . import views app_name = 'library' urlpatterns = [ path('', views.IndexView, name='index'), path('create/', views.CreateLibraryView, name='create'), ] mycastle(project)/urls.py: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('library.urls')) ] The views are wholly unremarkable: def IndexView(request): library_list = Library.objects.all() return render(request, 'library/index.html', {'library_list': library_list}) def CreateLibraryView(request): library_list = Library.objects.all() return render(request, 'library/create.html', {'library_list': library_list}) and a base template that just wants to connect in a meaningful way: <div class="page-header"> {% if user.is_authenticated %} <a href="{% url 'create' %}" class="top-menu"> <i class="fa fa-rocket"></i> Create a new library! </a> {% endif %} If I take the {% url 'create' %} line out - all the URLs resolve properly and happiness abounds. -
Can you set the value of a third option URL path() dictionary with a URL template tag parameter in django?
I need to pass an extra param to a url, but don't want to add it to the url pattern. Reading the django docs, I came across this, which is a bit like: urlpatterns = [ path('blog/<pk>/', views.year_archive, {'foo': 'bar'}), ] Sounds like what I need, but is there a way to set the value of 'bar' with a url tag, something like: data-url="{% url 'name_of_view' pk=obj.id foo=obj.bar %}" or... data-url="{% url 'name_of_view' obj.id obj.bar %}" or... ??? Also tried things like: path('blog/<pk>/', views.year_archive, {'foo': <bar>}), path('blog/<pk>/', views.year_archive, {'foo': self.bar}), #don't know why I think that would work Of course none of that works. I can pass 'obj.bar' through its own url pattern which is easy enough, but this breaks some other dependent code. Looking for another way, and the third option url dictionary seems promising if I can get it to work but so far can't set the value from the template. -

Django - Using forms.CheckboxSelectMultiple
