Re: What is the proper workflow before first migration?

[jgibson]

Hi,

Can you post the structure of your app, including project root?  Setting up 
a CustomUser Model is not a simple task, especially if you are new to the 
framework.

Re: What step am I missing?

[jgibson]

Pedro,

Can you provide us with the structure of your project?  For example:

/home/pedro/intro_django/
/home/pedro/intro_django/manage.py
/home/pedro/intro_django/apps/
/home/pedro/intro_django/apps/models.py
/home/pedro/intro_django/apps/views.py


Then let us know which where you are issuing the command "py manage.py 
runserver"

Thanks,

Re: Newbie question : running the makemigrations command in the terminal

That makes me think that the structure of your project looks something like 
this:

\munichliving_app\manage.py
\munichliving_app\apps\MunichLivingConfig\
\munichliving_app\apps\MunichLivingConfig\models.py
\munichliving_app\apps\MunichLivingConfig\views.py
\munichliving_app\apps\MunichLivingConfig\admin.py





And `OffererProfile` is defined inside models. Is that correct?

Re: How can I create schemas while writing creating table models.

Hi Sushen,

https://www.amvtek.com/blog/posts/2014/Jun/13/accessing-multiple-postgres-schemas-from-django/

This seems to be a rare use case, but that link has some options.  

Good Luck!

Re: How to inherit the user model in two apps in django rest,

[jgibson]

I'm not exactly sure what is happening with your models but a few places to 
investigate are these:

Since you are using `AbstractBaseUser` rather than `AbstractUser`:

* Looking at your code it seems like you missed assigning the 
*`USERNAME_FIELD`*
* You did not set your identifier (which I assume would be your username) 
to be *`unique=True`*

*https://docs.djangoproject.com/en/1.11/topics/auth/customizing/#django.contrib.auth.models.CustomUser.USERNAME_FIELD
 
*


Good Luck,

result = qs1.difference(qs2)

if Result is length 0 then all of 1 is in 2.

Re: test if model object fits into QuerySet without executing SQL?

[jgibson]

Tom,

Could you clarify "fits into"?

qs1 = Table.objects.all()
qs2 = Table.objects.filter(color='blue')


mo1 = qs1[0]


Are you trying to determine if mo1 is in qs2?

Best
