Python, django. AbstractUser Class. How to fix the problem with not updated field in Model?
Greetings to all and thanks for you time. Decided to create a CustomUser Model in my app based on app needs. Key notes: register by mobile phone with API verification. no password is needed (Token for mobile devices instead). all other fields are autofilled (username, country, birth_date, etc.) later on the user has opportunity to change the registration data. Everything works well. But I've found out that I can't change the username, using admin panel. It's not being updated when I try. Any suggestion how to fix this? And also I would be grateful for answering the second priority question: In models.py in class Users I overwrite the save() method. In this save method I first add a new User, get it's Id and then update the fields 'username' and 'email' joining 'id' at the end. From my point of view the way I do it is awkward. Any suggestions? models.py: from django.conf import settings from django.contrib.auth.models import ( BaseUserManager, AbstractBaseUser ) from django.core.validators import RegexValidator from django.db import models from django.db.models.signals import post_save from django.dispatch import receiver from rest_framework.authtoken.models import Token import phonenumbers class UsersManager(BaseUserManager): def create_user(self, mobile, password=None): """ Creates and saves a User with the given username … -
How I can give a view to my models.py in django?
My models.py File from django.db import models class Post(models.Model): name=models.CharField(max_length=200) content=models.CharField(max_length=200) pub_time=models.DateTimeField( auto_now=True) Can You tell me how I can put this in my views.py and HTML file? -
how can i filter items in some dictionaries?
My view: new = Product.objects.all().order_by('-time_add')[:10] discount = Product.objects.all().order_by('-discount')[:10] papular = Product.objects.annotate(num_likes=Count('liked')).order_by('-num_likes')[:10] free_shipping = Product.objects.filter(free_shipping=True).order_by('-time_add')[:10] items = {'new':new, 'discount':discount, 'papular':papular, 'free_shipping':free_shipping} return render(request, 'index.html', {'items':items}) I want to filter and show products in the above categories. But each Item may be in multiple categories. What should I do to mark products and avoid duplicate items when showing all of them in the template? Should I change my queries in views.py or change template tags? I test queries. they retrieve correct data. The output should be something like this: new: a, b, c, d, e discount: b, d, f, i papular: a, c, g free_shipping: d, f, h and all items without duplicates: all: a, b, c, d, e, f, g, h, i I have not any problem in HTML, CSS or js. The problem is just to mark products that are in two categories with python/tags in view/template. It's my template: <div class="featured__controls"> <ul> <li class="active" data-filter="*">All</li> <li data-filter=".popular">Popular</li> <li data-filter=".new">New</li> <li data-filter=".discount">Discount</li> <li data-filter=".free_shipping">Free Shipping</li> </ul> </div> . . . <div class="row featured__filter"> {% for key, value in items.items %} <div class="all {{key}}"> {% for i in vlaue %} <div class="featured__item"> <div class="featured__item__text"> <h6><a href="#">{{i.name}}</a></h6> <h5>{{i.price}}</h5> </div> </div> {% endfor … -

"exclude()" breaks the query in django
The query below returns the most liked entry of a title in my blog and it works fine: best_one_core=Like.objects.annotate(cnt=Count('entry')).filter(entry__title=id).order_by('-cnt').first() As I didn't want to modify it I am using default django user model's last_name field to keep track of blocked users. So if a user is blocked the last_name is blocked. What I want to do is to exclude blocked users from the results obtained by the query above. My solution is adding .exclude(user__last_name="blocked") to the query: best_one_core=Like.objects.annotate(cnt=Count('entry')).filter(entry__title=id).exclude(user__last_name="blocked").order_by('-cnt').first() This solution works for couple of other queries in the project apart from this one. I tried every possible placement so that's the problem for sure. I can share the models too if needed. -

django: access model field value without the primary key known
I have been boucing my head off the wall and cannot seem to figure out a way out of this probleme. I need to access a model object within a form. To identify which object to select, I only have access to one field (the name field), but that field is not the primary key. this is an issue because the django ways that I know only seem to work with the pk. In addition, I cannot modify the structure of the model because it messes up tenantmixin. here is the model: class Client(TenantMixin): id = models.AutoField(primary_key=True) name = models.CharField(max_length=100, default='') email = models.EmailField(default='') username = models.CharField(max_length=100, default='') ###### username password = models.CharField(max_length=100, default='') created_on = models.DateField(auto_now_add=True) auto_drop_schema = True and in the form I proceed as: field_name = 'email' obj = Client.objects.get(name= dbschema) field_object = Client._meta.get_field(field_name) field_value = field_object.value_from_object(obj) the issue is in the line: obj = Client.objects.get(name= dbschema) because it should be the primary that is the parameter inside the get() function. I cannot find a way to modify this statement to access the right object from the model. How could I tweak this to let me find the proper object from the name field? Thank you -

django test client CRUD API, unit testing
I want to write pure unit tests for my CRUD APP in django. Everyone use django tests or pytests, but I am really confused. Should I use test client to testing eg. POST method? Unit tests should be isolate and class should be test independently. We should use mocks DB etc. So why this code from https://medium.com/@ksarthak4ever/test-driven-development-tdd-in-django-and-django-rest-framework-drf-a889a8068cb7 is unit tests? class PrivateIngredientsApiTest(TestCase): #Test the private ingredients api def setUp(self): self.client = APIClient() self.user = get_user_model().objects.create_user( 'ksarthak4ever@gmail', 'hakunamatata' ) self.client.force_authenticate(self.user) def test_retrieve_ingredients_list(self): #Test retrieving a list of ingredients Ingredient.objects.create(user=self.user, name='Potato') Ingredient.objects.create(user=self.user, name='Peas') res = self.client.get(INGREDIENTS_URL)ingredients = Ingredient.objects.all().order_by('-name') serializer = IngredientSerializer(ingredients, many=True) self.assertEqual(res.status_code, status.HTTP_200_OK) self.assertEqual(res.data, serializer.data) For me this is functional test, not unit test.

How to silence Django fixed default date error W161
