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.

When to use get_user_model()

[tango ward]

Hi,

I am playing around with user registration. I came across a code where the
get_user_model() was assigned to a model in Meta class inside a form. I was
just wondering, what is the benefit of using the get_user_model() as Model
in a form instead of importing a class from models.py then use that class
as model of the form and when should I use it?

models.py
class RegUser(User):

def __str__(self):
return self.username

forms.py

class UserCreateForm(UserCreationForm):

class Meta:
fields = ('username', 'password1', 'password2')
model = get_user_model()


Thanks,
Jarvis

Hi Dylan,

 Thank you for the pointers. As you have suggested, after re-installing 
Python, I am able to continue my work. I must have screw up the path.

Re: Error with django-admin.py

[Dylan Reinhold]

This means your windows system has python files (.py) associated with
notepad not python.
It's okay, but anything you are going to run a python script like
django-admin.py or manage.py you need to run pythin first.

>  python django-admin.py startproject myapp
>  python manage.py

If you get an error about python comand not found you will need to fix the
path, the easy way might be to re run the python3 installer and make sure
add python to the path and associdate .py files to python is checked.

Strange problem with Django

[Tet Yeap]

Hi,

I was trying to learn Django. I have installed Python 3.6 and Django. 
The installation was successful. When I ran "django-admin startproject

program stop. What is wrong?

Thank you.

Re: Syntax Error when trying to migrate to Postgresql

[PASCUAL Eric]

Office oriented editors tend to take initiatives for making the text prettier 
(at least, according to their "standards" 😊).


For programming tasks, you'd better use real programming editors. There are a 
lot of very good ones which are free, and even full IDEs. I'd strongly suggest 
PyCharm Community Edition in this category (I'm not endorsed by JetBrain and 
have no connection at all with them, apart from being a very happy user of 
their products).

Looks like the quotes around the values are some non ascii character.
On my screen I see this:

‘

Change it to ' or "

Did you copy/paste that from Word perhaps?
