#django

my internet messed up, in case anyone responded to me

LiftLeft: Nobody did - but this channel has logs anyway. https://botbot.me/freenode/django/

ok

LiftLeft: There is https://docs.djangoproject.com/en/2.1/ref/contr..., which happens on _any_ login/logout.

IIRC there's an attribute on an authenticated User that indicates which backend was used to authenticate them.

LiftLeft: I've not used the package you mentioned, but a quick read of the docs there seems to indicate that it doesn't generate signals: you'll need to handle it in django.

maybe I should I use a different module

I dunno

Hi guys! What's wrong with this: https://dpaste.de/Sd8v

dziadekludojadek: why do you say there is something wrong with it?

when I put print inside if instruction it never goes inside method.request == post

dziadekludojadek: try "POST" instead of "post"

dziadekludojadek: or, print(request.method) to see

ok it's wired

it says GET when I'm loading and POST when I'm clicking submit

so it should go inside if instruction

dziadekludojadek: did you change the code to check for "POST" instead of "post"?

dziadekludojadek: you really shouldn't be using relative paths in your action... better to use {% url %}

and you should test "if request.method == 'POST': " ... case is important

nedbat: it doesn't help

dziadekludojadek: pastebin the latest code.

monring, nedbat

FunkyBob: you too

if request.method == 'POST': doesn't work but log said method is POST when sending form

dziadekludojadek: pastebin the latest code and output

dziadekludojadek: are you certain (a) you're editing the right file? (b) the request is hitting the view function you think it is? and (c) than runserver reloaded correctly?

Ok it wokrs!

Don't ask :)

I already have the login/logout functionality. Now how can I limit access or make invisible some menu option according user login?

I have to add users and groups and roles in the admin page first?

do you mean django.contrib.admin /

?

if so, it already has users and groups... and permissions... in the views and template context

yeah so first i access the admin panel and create my users and assign them permissions?

and then I guess in the template and view I have to limit the access innit?

that's one way to do it, sure

yes

the auth docs cover how this is handled...

the auth context manager provides the user and a handy, easy-to-use proxy to permissions

is this the link? https://docs.djangoproject.com/en/2.1/topics/au...

no

close

you're not trying to customise auth, just use it

ok

There was a suggestion that if you think maybe you'll change something to do with the auth models at some point, then maybe consider doing a subclass right from the get-go; even if you don't make any model changes right now, it's far easier to add fields to a custom auth model than it is to migrate to one.

I can confirm from experience what schinckel said.

oh bugger the little language & version selectors at the bottom of the docs don't appear to be reachable via keyboard only

via tabbing or vimium

shangxiao: can you figure out if that's Sphinx, or something custom we did to it?

ubernostrum: ah happy to take a look but would need to be later tonight or on the weekend :)

Sure. I may have some time in the next couple days to look into it, too.

Just curious where the problem is, in order to figure out how to fix it.

👍

ubernostrum: do you know why django docs created the snipped:: directive?

I was working on a suggestion from someone at the pyconau sprints, and ran into that

FunkyBob: I'm not sure. Commented in -dev recently that I think a few of the custom directives are obsolete.

ubernostrum: ok, thanks

since ISTM code-block can do all it does, and more

might make it my train project

Anyone used a postgres_fdw table in their django project?

not yet

ok i have created some users and assign them to a group. how can i limit the menu options based on their groups? is there something like this {% if user.is_authenticated and user.group=groupname %} ?

sydbarret: no need to test is_authenticated .... the AnonymousUser never has groups...

however, there is no template support for testing group membership

groups are intended mostly as a convenient way to manage bulk-assignment of permissions

so i need to check based on the permission instead?

sydbarret, maybe you can create your own templatetag with a simple `user.groups.filter(name='groupname').exists()` check

aldnav can I have also {% if user.is_authenticated and user.is_staff %} ?

sydbarret: those are your two options...

sydbarret: you can

ok th anks

no need to keep checking user.is_authenticated if you ALSO check for something _only_ an authenticated user can have

[like is_staff, or groups, or perms]

You probably don't want to have a whole stack of tests against group membership: the django permissions stuff is pretty heavily optimised to prevent multiple db queries.

If you go around querying user.groups.filter(...).exists() you'll wind up with a stack of extra queries.

You could write something that is similar to django's permissions checks: where it loads up _all_ permissions for a user when the first permissions check is made, but for groups.

We do something similar to this for features based on the "company" a user belongs to.
