the way I explain to myself is "annotate in queryset" is kinda like "@property decorator on Model's method"

i don't answer DM, anything ask in public

I have created a django project. Now I want to use it online means I want to use it from my mobile. Where can I configure it so that I host it online for my personal use without paying or at very very affordable

you can expose your localhost using ngrok if its just for personal use ( https://ngrok.com/ ) and free.

Hello I have a problem I wanted the (forgot my password) part of the site (password recovery) to work with both (email and phone number). I made CustomPasswordResetView which inherits from (PasswordResetView). token = default_token_generator.make_token(user) And with this line, I made a token and sent it to the user as a link But this link only works for people who only have a phone number in their account. And it doesn't work for these people (have only email, have email and phone number, don't have phone number and email) and when you click on the link it brings Bad Token page. Can anyone help?

I can not deploy the site on the hosting, please help

I have a field in model model called followings like this: followings = models.ManyToManyField(         'self',         symmetrical=False,         help_text='Users to follow.',         related_name='followers',         blank=True,     ) In my model admin, I can change followings but I cannot see followers What can I do to have a followers list in my model admin?

symmetrical=True should work

symmetrical=True should work

I don't want it to be symmetrical

I can not deploy the site on the hosting, please help

Provide more details

I don't want it to be symmetrical

then you have to create another relationship between the followers and the followings or a computed field

then you have to create another relationship between the followers and the followings or a computed field

That's not what I'm looking for I think I can use a custom form for my admin page but don't know have to populate followers part of the form

Which part I will make it clear.? I have a CustomeUser , then when trying to add a user in ADMIN panel it just shows username, password, confirm password. Not Email Field

Have you solved it

does anyone have experience using the parameterized library?

I'm looking to get some clarification on its usage. I wrote a bunch of unit tests, and I'm using parameterized.expand to help with easily creating tests that have mostly the same code but different inputs. I was thinking I could stack the parameterized.expand decorator, like so: @parameterized.expand(['some', 'val'], name_func=lambda f, param_num, param_args: f"{f.__name__}_{param_args[0]") @parameterized.expand(['diff', 'other'], name_func=lambda f, param_num, param_args: f"{f.__name__}_{param_args[0]") def test_some_unit_test(self, one, two): .... this appears not to be the case however, as for the upper parameterized.expand decorator, I'm getting an error stating that NoneType has no attribute __name__ when accessing f.__name__ in the f-string. I have my intuition on why this is, but that's neither here nor there. is there any feasible way to stack expand decorators or the like without issue? I really would hate to have to collapse all my expand decs. that would be a pain in the ass

In an interview they asked have you ever edited the controller. So am still little bit confused

What a framework like ASP .NET calls a controller is equivalent to what Django calls a View It uses MVC, Django uses MVT, The view in MVC is necessarily what the sees and the controller handles the input and interaction. But in Django, the Templates handle what the user sees and the views handle input and all. Just read into it a little bit more. People forget that software design patterns are not universal and forget to use the correct software design pattern for the framework/tool. I hope that clears up your confusion even a little a bit.

Any specific reason you are using ManyToMany field in your model? Quick observation looking at your code: 1) Avoid using upper cases in db_table. Django documentation specifies it could create problems with some databases like MySQL 2) Avoid using space when you specify db_table field. Replace space by underscore

Noted thanks but my issue is relationship to be specific one to one relationship

The parent I'd is not being filled in the child table thereby is giving me parent_id can not be null

I do not know the background of your use-case. But you can specify all the details like first, name, last name, etc in the Patient model. You can keep only the created and updated fields in your CommonField model.

So it is possible that a patient can have more than one emergency right? I think it your Emergency model should specify patient field as a ForeignKey to the Patient model

Am understand you and thanks just that the patient only have right to one emergency

That is why I specified it as one to one

Also I see you have specified unique=True in the Emergency model. Try changing it to primary_key=True. OneToOneField will have exactly the same number of records as that of the Patient model. So setting unique=True will not make sense.

My major challenge is that the Id from the parent table that is not being inherited in the child

Also I see you have specified unique=True in the Emergency model. Try changing it to primary_key=True. OneToOneField will have exactly the same number of records as that of the Patient model. So setting unique=True will not make sense.

Ok thanks alot but I tried that and I makemigration a fresh to see if that is the issue but it did not work for me

Try changing your class from Emergency(CommonField) to Emergency(models.Model) and see if it fixes the problem.

ok but that will not make me achieve the objective

ok but that will not make me achieve the objective

Sorry, what's the objective Because Emergency is inheriting from commonField, and it also has a patient field which is a one to one with Patient model that's also inheriting from commonfield

Is there any reason for that

Hi. Can we create User model for admin authentication and Customer model for api authentication Issue that im facing is im not able to create jwt token for customer

Hi How do you save an array of values from multiple checkboxes to a model? Also can you tell me which model field and form widget should be used? I used MultipleChoiceField with CheckboxSelectMultiple widget in the model form, but when it goes to the View, the if form.is_valid() condition returns None. I don't know how to tackle this one particular field. Please help!

Hi. Can we create User model for admin authentication and Customer model for api authentication Issue that im facing is im not able to create jwt token for customer

User model will be responsible for the token generation which will be configured in settings file. I am suggesting you if you want to create customer you can take is_cusomer field in user model insted of taking a separate model. Here you surely have to take an abstract base user inherited in your user model and have to configure the user model in settings file.

You have to use Django formset

Sorry, what's the objective Because Emergency is inheriting from commonField, and it also has a patient field which is a one to one with Patient model that's also inheriting from commonfield

Commonfield is an abstract class

Sorry, what's the objective Because Emergency is inheriting from commonField, and it also has a patient field which is a one to one with Patient model that's also inheriting from commonfield

Commonfield is not created in the db since it is set as abstract

My challenge is on one to one relationship the parent Id is not inherited it the child so it's giving me parent_id is null which is against the constrain

Okay share your code with pastebin let me check it out

Hey ya'll. Quick question how to make EmailField in Signup form , Required . In CBW?

You can make this field as required = True in your forms.py. Even if the model field is optional, the user will be forced to enter an email in the form. Make sure add the form_class in your CBV.
