django models cyclic import
I have read some relevant posts on the issue on mutual imports (circular). I am working on a django app, here's how I run to an issue: I have two apps, first one articles, second one tags my article model have a many to many field, to indicate relevant tags: articles/models.py from django.db import models from tags.models import Tag class Article(models.Model): tags = models.ManyToManyField(Tag) however, in my tags app, I also need to import Article model to achieve the methods: tags/models.py from django.db import models from articles.models import Article # Create your models here. class Tag(models.Model): title = models.CharField(max_length=100) content = models.CharField(max_length=255) def getAritcleLength(): pass def getQuestionLength(): pass I usually use a module to combine those class definitions, normally won't run into issue according to method resolution order. However, in django the workflow we need to put classes into separated folders, I will be so glad for any suggestion. -
Access and modify Django DB without login in as superuser
I have a newbie question here. I'm currently working on a site where the user can add items to a model I created. The thing works fine if I'm logged in as super admin in the Django admin panel, but if I'm not, the CSRF verification doesn't work and I can't operate. Is this a "Debug: True" thing? Once I'm ready to production and turn debug off, will it work without login? Thanks! -
How to execute django runserver and python script at the same time (on one line in cmd)
I have wrote a python script which automatically uploads files from a given folder to a django modell. I want this script running while django server is running. My script runs perfectly when I run it in pycharm console. I have tried a few command to achieve this: python manage.py runserver & python manage.py shell < myscript.py python manage.py runserver & python manage.py runscript -v3 myscript In the first case nothing happens until I press ctrl+c, then it display errors "unexpected indent" for every single row of my code. In the second case my script starts to run only when I press ctrl+c (so my django server is shut down and my script is executed). I am using windows so celery is not a good alternative for me (and celery is overkill for such a simple task like that). -

problems dropdown filter saving data in the database
I have a problem with a select that filters the other. I did all the filtering correctly from the frontend point of view but in the backend I can not save the data. This is the error: select a valid choise. That choice is not one of the available choices.

How can I edit or customize the required characters of a username field?
I'm making a blog type website, and it's pretty much done but earlier today I realized a major flaw in it. When creating creating a username (when registering or editing one's profile) it asks for certain characters, but it won't allow me to have spaces in my name. For example if I wanted my username to be "Winston Pichardo", it won't be possible because that will trigger the error that says "only letters and digits as @/./+/-/_ are allowed". So how can I edit these 'requirements' to allow spaces in the username? I'm using the default django forms and combining those with Crispy Forms to make it all work. these are some examples of my code: forms.py class UserRegisterForm(UserCreationForm): email = forms.EmailField( label= 'Correo Electrónico', required=True, ) username = forms.CharField( label = 'Nombre de Usuario', required=True, ) password1 = forms.CharField( label = "Contraseña", required=True ) password2 = forms.CharField( label = "Confirmar Contraseña", required=True ) class Meta: model = User fields = ['username', 'email', 'password1', 'password2'] class UserUpdateForm(forms.ModelForm): email = forms.EmailField( label='Correo Electrónico', required=True ) username = forms.CharField( required=True, label='Nombre de Usuario' ) class Meta: model = User fields = ['username', 'email'] class ProfileUpdateForm(forms.ModelForm): image = forms.ImageField( label = 'Foto de … -
Is there a built-in way to set a maximum relations size for ManyToManyField?
Initially I had an ArrayField that could have a maximum of 3 enums inside it. But with my project getting more complex, I had to change this field to a separate model, which has other fields along (but the enum still the same). The target model, which previously contained the ArrayField would then need a ManyToMany in order to correctly reference these multiple instances, with a limit of 3 instances max. I know I could override the save method in order to check this before saving, but I was curious if there's a built-in way in the MTM field to do this kind of check -

What data format is this in google gantt chart? How can I return a format like this in Django?
I'm trying to integrate the google Gantt chart into my Django project, there's a model for tasks, the model has 2 date fields already, one is a start date and another is the due date.

Django psycopg2.errors.InvalidSchemaName: no schema has been selected to create in
I am trying to configure PostgreSQL in my Django project with a custom schema. My settings are: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': os.environ['DB_DATABASE'], 'USER': os.environ['DB_USERNAME'], 'PASSWORD': os.environ['DB_PASSWORD'], 'HOST': os.environ.get('DB_HOST', 'localhost'), 'PORT': os.environ.get('DB_PORT', '5432'), 'OPTIONS': { 'options': '-c search_path=my_custom_schema', }, } } I want django system tables to be created in the schema my_custom_schema as well.
