Using models clean method for fields validation
I need to check the model field for a list of available items before I save them to the database. models.py class Vendors(models.Model): COUNTRY_CHOICES = tuple(countries) ... country = models.CharField(max_length=45, choices=COUNTRY_CHOICES) ... class for saving models class CsvToDatabase(APIView): def post(self, request, format=None): data = request.data for key, vendor in data.items(): Vendors( ..., country=vendor['Country'], ..., ).save() return Response({'received data': request.data, 'message': 'Vendors from vendors_list were successfully added to the database'}) For validation Im added clean method to models def clean(self): if self.country not in [x[1] for x in countries]: print("Invoke save") raise ValidationError(detail="Country name does not match to the country list ") But it doesnt work Next step I added the same code to method save def save(self): if self.country not in [x[1] for x in countries]: print("Invoke save") raise ValidationError(detail="Country name does not match to the country list ") And it works, but I read that using validation in the save method is not correct. And the correct method for use - clean, why in my case it does not work? -

Django - Diffrent ListViews
I have a problem, I'm making a simple blog and I want to have drafts, archive and main list of posts.

AWS Elastic Beanstalk, wont update django.config with "eb deploy"
I've deployed a API application to AWS Elastic Beanstalk written in python and django. I'm now developing the frontend from which I'm trying to send a simple get request to the AWS python server. Trying different solutions to the CORS header issue I added: files: "/etc/httpd/conf.d/cors.conf" : mode: "000644" owner: root group: root content: | <Location "/"> Header set Access-Control-Allow-Origin: * Header set Access-Control-Allow-Methods: "POST, GET, PUT, DELETE, OPTIONS" Header add Access-Control-Allow-Headers: "Authorization, Content-Type, Accept" Header set Access-Control-Allow-Credentials: true SetOutputFilter DEFLATE </Location> to the django.config file which made it work on AWS but not locally (the django.config file is located in .ebextensions file). I decided to instead use the 'django-cors-headers' middleware so that it would work both locally and on AWS. But now it wont work on AWS since it registers multiple Access-Control-Allow-Origin domains. So after removing the above files: code from django.config the problem persisted so the reasonable problem would be that the header is added both by the middleware and by the django.config code which I'm not able to remove. Could someone help me find a solution? -

Python: Object to list of tuples extraction
I have an object in the following format: { 'af': { 'bidi': False, 'code': 'af', 'name': 'Afrikaans', 'name_local': 'Afrikaans' }, 'ar': { 'bidi': True, 'code': 'ar', 'name': 'Arabic', 'name_local': 'العربيّة' }, ... } This is a list of locales as found in django.conf.locale.LANG_INFO. (see here for full reference: https://github.com/django/django/blob/master/django/conf/locale/init.py). Now, I am hoping to utilise this list in a model class: locale = models.CharField(max_length=5, choices=get_locale_choices(), default='en') Such that I have the following utility function: from django.conf.locale import LANG_INFO def get_locale_choices(): return ? Now, that ? that gets returned, I'd like to be in the following format: [ ('af', 'Afrikaans'), ('ar', 'Arabic'), ... ] My question is this, how would I turn the LANG_INFO dictionary into the above list of tuples? It feels like something like this is close: a_dict = {'color': 'blue', 'fruit': 'apple', 'pet': 'dog'} d_items = a_dict.items() d_items # Here d_items is a view of items dict_items([('color', 'blue'), ('fruit', 'apple'), ('pet', 'dog')]) But...hmmm, not sure? I want to extract a sub-value from the key item... -
What are the differences between using self.add_error() and raising a ValidationError()?
You can throw a validation error in 2 ways. The first is with self.add_error() and the second with raise ValidationError(). I've read that when you use self.add_error('field1','description here') then field1 is also automatically removed from the cleaned_data list and i assume a ValidationError object is also added to the self.errors list, is this correct? But what happens when you don't choose to use self.add_error and opt for using raise ValidationError instead? Is this object also automatically added to the errors list behind the scenes? And how would you display this error message as caption under the correct invalid field? Thank you -

How to define a foreign key in an Django app model which is ignored if a sub-app is not installed
I have a base app which is used by sub-apps. I have an AbstractUser defined in the base app and I need to add a relation to a sub-app model if the sub-app is installed. I understand that my new field will be present in the user table in the database, but with a null value if the sub-app is note installed. My problem is to reference the foreign key I had to a model that does not exists if the sub-apps is not installed. Does I need to transfer the model from the sub-apps to the base app or is there another solution like a conditionnal foreign key constraint in my AbstractUser model. -
Is it possible to add a postgresql trigger to notify my Django app when a table changes?
My Django app connects to a PostgreSQL 9.x database. To this database, a legacy Java app is connected, too. So two different apps use the same database. Is it possible for PostgreSQL to notify my Django (2.2.x) app when a table changes? I know that I can create a cron job to check on tables on a timely basis, but the Server administrator does not let me do cron jobs (why?) and the Java guy is too busy on other things to do code rewiring (so I can't ask him him to send me url requests after table changes). Or any other idea would be much appreciated. Thanks. -

Django Rest Framework - How to modeling and serialing data from Mssql Stored Procedure
I'm new to Django, and i'm trying to build my app that pulling some data from mssql database, i'll appreciate all the help that you can provide.

Django Queryset ManyToMany
I'm trying to only show a user the Portfolios that they created but right now the form shows the user all the portfolios created. Ideally, I would like to filter this in the view.py but maybe filtering in the models.py could also be a good approach as I'll need this in several forms throughout the app. A post can belong to many different portfolios. Similar to how a hiking article may belong to several categories (outdoors, fitness, nature, travel, etc.) The only thing is I only want to show the user the "categories" or in our case the Portfolios that they have created and not of other users. I've been on this for several days now and read Djangos docs on queryset and manytomany plus gone through countless other guides and SOF questions. Am I overcomplicating this whole thing?

How to Redirect/Access Django Admin Page from Angular UI - Docker
We have used Docker environment which has two images. one for Back-end(Django) and another for front-end(Angular). In the Docker we have blocked(Back-end is running in port 8000) the direct back-end port access. only through front-end the backed will be access. I can access all the urls from frond-end. but I cannot access Django admin page. Because I am blocking the direct port access for back-end. Example: 1. Before blocking Port in docker-compose.yml, when access admin page, it will work http://domain_name:8000/api/user - **Accessible** http://domain_name:8000/admin - **Accessible** 2. After blocking Port in docker-compose.yml, when access admin page, it will work http://domain_name/api/user - **Accessible** http://domain_name/admin - **Not-Accessible** Kindly help me to access Django admin page. even if it the port is blocked. -

I want to change the default permission name created by django after migrating django model. The docs says Providing default_permissions = [] in the class Meta works but It must be specified on the model before the model is created by migrate in order to prevent any omitted permissions from being created. But is it possible to change the permission Name (codename also if possible) after the model migration also ? class ContactPage(models.Model): full_name = models.CharField(max_length=255) email = models.EmailField() msg = models.TextField() sent_on = models.DateTimeField(auto_now_add=True) def __str__(self): return self.full_name class Meta: default_permissions = [] # works in the first migrate permissions = [ ('can_view_contacts', 'Can View Contacts'), ('can_delete_contacts', 'Can Delete Contacts'), ]
