#django

https://github.com/dfunckt/django-rules looks simple to implement. Django Guardian seems like it could work, too, but seems more complex. Which do you recommend or do you have another recommendation?

I'm using the latest Django, btw.

I've used guardian very successfully

hello

i created a custom user model for a new project that doesn't have a username field, only an email field, and set the REQUIRED_FIELDS etc properly, but "createsuperuser" complains that it didn't receive a username

what's the proper fix for that? i got that error on multiple projects

stavros: can you show the model and error?

knbk, sure: https://www.pastery.net/etpeja/

stavros: ran into that issue earlier this month. i just created a new user manager and copied the existing createsuperuser method

OtherAllan, yeah, that seems to be the only solution, but i would have expected it to work, seems like a Django bug

mcspud, Is there a way to create the roles using /admin with guardian?

OtherAllan, can you paste me your code to save me digging through the manager docs?

stavros: you changed USERNAME_FIELD, but you didn't actually remove the username field that's defined on AbstractUser. You can set `username = None` (and run makemigrations/migrate)

cilkay - I'd create the groups programmatically, and assign permissions to them programmatically also

cilkay - it basically creates a "default state"

stavros - you need to override the baseusermanager

(stavros: assuming you don't want the username field at all)

knbk, if i do that, it crashes because the UserAdmin refers to "username" in its ordering field

stavros: knbk's solution might work and is probably better. i cant completely remove my username field for now

mcspud, I'll already have the players, coaches, teams, and league in models so it would be nice to be able to grant appropriate permissions to them on an object or group level.

cilkay - you can do it through admin, but that is a cumbersome manual process

I'd tie groups into other resources

Like this

stavros: https://dpaste.de/Purz#L12 . Hacky, i know, but it works for now

OtherAllan, that'll work, thanks

stavros: just subclass UserAdmin and change it

i'm also trying to just add my own useradmin, yeah

knbk, it's just a bit cumbersome to find the current fields, but i'm looking for the source now

knbk, nah, createsuperuser still fails

i think it's what OtherAllan said

cilkay - I do this a lot

Its a nice, predictable way to control authorisation during resource creation

Your only manual step is putting people in the groups

OtherAllan, you override it as objects = NewUserManager() on the User, right?

yep

mcspud, Thanks. That looks simple enough. I was planning on assigning users to groups on import anyway. This is not a self-registration site.

OtherAllan, still fails with an odd error: "TypeError: 'username' is an invalid keyword argument for this function" when your _create_user is trying to call self.model()

sorry, i mean the UserManager's _create_user

are you doing something like self._create_user(username=username) ?

do we need to override create_user too?

no, UserManager._create_user is doing that

user = self.model(username=username, email=email, **extra_fields)

i wonder if i should just override both and just call super() with username=email

did you remove username from your model? (i.e. username = None) ? that probably would cause it

i still have it on mine

OtherAllan, ah yes, i did

that'd do it, thanks... let me experiment a bit

this feels like a bug, you shouldn't have to jump through all these hoops to remove the username field when this is an explicitly sanctioned use case in the docs

yeah kind of i guess. i didnt catch it until a lot later since i dont use ./manage.py createsuperuser much

all other usages in django work fine

i only use it once, but i'd like to do it "properly", and it doesn't feel like it's proper unless things work

but yeah, for my last project i just ignored it and things work fine

i just decided now to figure out how to fix it, but apparently there's no easy fix

OtherAllan, the only thing that works is taking the whole UserManager class, overriding things and removing username, in case you're interested

the docs explicitly say that if you don't use a field `username` or some of the other fields on AbstractUser, you need to define your own create_(super)user methods -- https://docs.djangoproject.com/en/2.0/topics/au...

ah. well there you have it

ah, i see, thanks

anyone hiring?

Can I use/consume java APIs with django?

Yes

As long as you aren't serializing classes

In java parlance, you aren't "marshalling objects"

thanks. Can you point me at some reading material on the subject?

go and read about XML or REST

They are standard, web-friendly data formats

For django-specific stuff check out django-rest-framework or django-nap

thank you

mcspud: you mean XML or JSON

yeah that

I gave you a bump FunkyBob

your welcome
