Re: When to use get_user_model()

[Scot Hacker]

It's good future-proofing, in case you ever change the User model in your 
project. In real life, that's highly unlikely, but where it's *really 
important* to use get_user_model() is when you are writing reusable apps 
for distribution. If your app is intended to be dropped into any existing 
Django project, you have no idea what User model is in use by other 
people's projects. This layer of abstraction makes it possible for 
re-usable apps that depend on some User model existing to work no matter 
what.

Re: When to use get_user_model()

[Xavier Paniello]

Hi tangoward15,

Django will use auth.User as the user model in the system, unless you 
change AUTH_USER_MODEL = RegUser in settings.py

Be carefull, to change the user model has some particularities you can read 
in docs (warning section):
https://docs.djangoproject.com/en/2.0/ref/settings/#auth-user-model

Other option to extend auth.User is a model with a one2one field related to 
auth.User, or a proxy model:
https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html

Salut!

Re: When to use get_user_model()

@Mukul Agrawal,

thanks, i'll read this.


@Xavier,

the model in forms.py, does it mean it will use the RegUser class from the
models.py? Sorry, I am confuse.

Re: When to use get_user_model()

[Xavier Paniello]

Hi tangoward15,

The User model by default is auth.User, but you can define a custom one and 
reference it at settings: 
https://docs.djangoproject.com/en/2.0/ref/settings/#auth-user-model

So, get_user_model() will return the model defined at AUTH_USER_MODEL 
setting.

Salut!

Re: When to use get_user_model()

[tango ward]

I also checked the documentation of it but I am confuse. It says "Instead
of referring to User

directly, you should reference the user model using
django.contrib.auth.get_user_model(). This method will return the currently
active user model – the custom user model if one is specified, or User

otherwise." When it says "currently active user mode" is it the model that
I created in models.py or the one that is currently logged in to the
website? what does "or User otherwise" mean?

My apologies for asking too many questions.
