add avatar in AbstractUser and Django-allauth
My code works fine and I do migration to add avatar to my user.

Django: Problem with saving model instances with ForeignKey-relation to database
I would like to create and save model instances with Django. These are my models: class Customer(models.Model): id = models.IntegerField(primary_key=True, unique=True) user = models.OneToOneField(User, on_delete=models.CASCADE) first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) ... class Order(models.Model): id = models.IntegerField(primary_key=True, unique=True) customer = models.ForeignKey(Customer, on_delete=models.CASCADE) comment = models.TextField() ... While processing a form, customer will be created: customer = Customer.objects.create( user=user, first_name=storage_space_order["customer_firstname"], last_name=storage_space_order["customer_lastname"], ) As far as I've learned, Django will save the object on calling create as well. Now, I would like to create my order object Order.objects.create( customer=customer, comment=data["customer_comments"], ... ) While saving, I get the following error message: save() prohibited to prevent data loss due to unsaved related customer What I don't get; customer is already there and saved in the database. There are no changes on the customer in between. Also, I've tried customer_id=customer.id/pk, - but both ID and PK return None. Why is this and what do I need to change? Loading the object again is not the preferred way, as I only got the ID which marks it as unique. Thanks for your input :) -
How can i, from a simple form, insert many values into the database in Django?
I have a simple form, like this: <form method="post"> {% csrf_token %} {{ add_boat.non_field_errors }} <div class="form-group"> {{ add_boat_type.name.errors }} <label for="{{ add_boat.name.id_for_label }}">Type</label> <input type="text" name="{{ add_boat.name.html_name }}" class="form-control" placeholder="Ex. Suspekt" value="{{ name.value }}" id="{{ add_boat.name.id_for_label }}"> </div> <div class="form-group"> <input type="hidden" name="{{ add_boat.added_by.html_name }}" id="{{ add_boat.added_by.id_for_label }}" value="{{ user.id }}"> </div> <div class="form-group"> <input type="submit" class="btn btn-primary" value="Add"> </div> </form> where one of the form groups handles a name. The other one is hidden and is for adding what user added this specific entry (this can probably be done in a better way in my model or my view...). But my question is: do i need a hidden form group for every value I want to enter into the database? If i don't include the hidden form group above I get an error saying that that field can not be empty per the database definition (null = 0). I would idealy like to insert a lot of data into the database based on only the name from the form. My form class looks like this: class BoatForm(ModelForm): class Meta: model = Boat fields = [ 'name', 'added_by' ] and my iew looks like this: if(request.user.is_authenticated): add_boat_form = BoatForm(request.POST … -

Django Social Authentication Create New User With Custom Model
I'm trying to develop a Facebook social authentication feature on an application that uses a custom Django user model and django-rest-framework-social-oauth2 as the social authentication package. My custom user model is called 'Account' and it inherits from the AbstractBaseUser class. The Account model is shown below: class Account(AbstractBaseUser): # Account model fields: email = models.EmailField(verbose_name='email', max_length=60, unique=True) username = models.CharField(max_length=30, unique=True) first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) date_joined = models.DateTimeField(verbose_name='date joined', auto_now_add=True) last_login = models.DateTimeField(verbose_name='last login', auto_now=True) is_admin = models.BooleanField(default=False) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) # The user will log in with their email instead of username: USERNAME_FIELD = 'email' # Required fields when registering, other than the email: REQUIRED_FIELDS = ['username', 'first_name', 'last_name'] # Telling the Account object how to use the account manager: objects = MyAccountManager() The function that handles creating a new user is called 'create_user' and is defined within my custom written MyAccountManager class which extends the Django BaseUserManager class. This is given below: class MyAccountManager(BaseUserManager): def create_user(self, email, username, first_name, last_name, password=None): # Checking to see if correct function parameters have been passed in: if not email: raise ValueError('Users must have an email address') if not username: raise ValueError('Users must have … -
How to use sekizai's addtoblock tag inside a form widget template
I am writing a custom form field which has a custom widget. The widget needs some static assets. Its template looks like this: {% load sekizai_tags static %} <div id="myWidget"> ... </div> {% addtoblock "css" %} <link rel="stylesheet" href="{% static 'my_app/css/widget.css' %}">{% endaddtoblock %} {% addtoblock "js" %} <script src="{% static 'my_app/js/widget.js' %}"></script>{% endaddtoblock %} However, this doesn't work. I get: You must enable the 'sekizai.context_processors.sekizai' template context processor or use 'sekizai.context.SekizaiContext' to render your templates. I guess this is because the form (and widget) has no access to the request object?! Is there a way around this? I found in the sekizai source a mention of SekizaiContext as... An alternative context to be used instead of RequestContext in places where no request is available. ... but I can't figure out how exactly I would do that. Note that I do not want to start passing the request around. This would not be an acceptable solution, as my custom field is meant to be reusable; it should just work in any form without further modifications. -
how to design a user based DB system in django
I am working on a Django system that lets multiple individual users store the same type of files and related data. for now, I am storing the user Id in the individual related tables. (i.e) table =>User(id,name,password,email) table =>File(id,url,User.Id) but now I need to store its related data, in few other tables.(i.e) table =>FileInfo(id,File.id,desc,otherInfo) so now when I query the FileInfo table from a user's login, it is fetching info of all the files(i.e all records) since there is no hold in the table. it is also not feasible to store user.id in all the tables, (maybe in the future it may grow to tens or hundreds of table) so kindly suggest me(design change that can to retrieve the current user data alone or any django functionality that supports this use case or any Django package that helps to achieve it) how can I get the data that pertains to the current logged in user without explicitly storing the userid in every table. -
How to restrict overlapping datetimes in django model at DB level using CheckConstraint
I have the following fields in my Model: class Event(models.Model): starts = models.DateTimeField() ends = models.DateTimeField() I want to restrict overlapping dates (starts, ends). I have managed to do this in model validation, but now I want this enforced at database level such that an IntegrityError exception is thrown if an insert happens outside the model's save method. My Validation was as follows: ... def clean(self): if self.starts and self.ends: if self.__class__.objects.filter( models.Q(ends__gte=self.starts, starts__lt=self.starts) | models.Q(ends__gte=self.ends, starts__lt=self.ends) | models.Q(starts__gt=self.starts, ends__lt=self.ends) ).exists(): raise ValidationError('Event times overlap with existing record!') This works. Say an event starting 2020 Oct 11 @ 19:00, and ending 2020 Oct 11 @ 20:00, the following values will prompt an overlap: same date, starting @ 18:00, ending @ 21:00 same date, starting @ 19:30, ending @ 19:50 same date, starting @ 19:30, ending @ 20:50 But there are situations where the model's .clean() method will not be invoked, which may result in invalid data to be inserted. My question is, how can I enforce a constraint on the model, which will apply on the database itself, like unique_together does. I have used postgres specific fields like DateRangeField but in this case, their functionality is limited as they can … -
Google authentication using django-rest-auth and allauth

I am able to get the code from the redirect but when I access http://127.0.0.1:8000/auth/google/ I see it's asking for a two fields (access_token, code).

Django wont save form data to postgres database

Cross-app join queries for retrieving linked data
I am working on an app that will store customers and addresses in seperate apps. Some addresses will be customer linked, which I planned on doing by storing the pk for the customer against the address and for primary addresses I planned to link the opposite (address pk to customer field). I am unsure on how to pull the data from both apps into the table I'm populating to "view all". def customers(request): customer_list = customer.objects.all() context = { 'customer_list': customer_list, } return render(request, 'customers.html', context) The goal I am trying to achieve is to turn these 2 pk's into the addresses stored in my address app. I tried to implement foreignkeys with my current structure and was returned an error when creating a foreignkey in my customer model linking to addresses; primary_address = models.ForeignKey('addresses.addresses', on_delete=models.CASCADE) #django.db.utils.OperationalError: no such column: customers_customer.primary_address_id The goal I have set is to replace the primary keys in the below table with the addresses from the address model.

Part written in Python models.py class Topping(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=50) def __str__(self): return self.name class Pizza(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=50) toppings = models.ManyToManyField(Topping) schema.py class Query(graphene.ObjectType): pizza = graphene.List(PizzaType) topping = graphene.List(ToppingType) @staticmethod def resolve_pizza(parent, info): return Pizza.objects.all() @staticmethod def resolve_topping(parent, info): return Topping.objects.all() types.py class ToppingType(graphene.ObjectType): id = graphene.NonNull(graphene.Int) name = graphene.NonNull(graphene.String) class PizzaType(graphene.ObjectType): id = graphene.NonNull(graphene.Int) name = graphene.NonNull(graphene.String) toppings = graphene.List(ToppingType) Part written in Graphql query graphql query { pizza{ name toppings { name } } } response graphql { "errors": [ { "message": "User Error: expected iterable, but did not find one for field PizzaType.toppings." } ], "data": { "pizza": [ { "name": "mafia", "toppings": null } ] } }
