And the problem is the manytomany relationship between establecimiento and tipo de comida

Wheneveri try establecimiento.tipodecomida_set.all() works fine

But tipodecomida.establecimientos throws an error

This error

Any ideas?

hello guys o/

Hi Paradisee

is there a way to do: foo = Foo.objects.all() and don't make queries when you do: foo.baz ?

.select_related() ?

mm..

how does it work?

im reading: https://docs.djangoproject.com/en/1.9/ref/model...

in the example there's this: e = Entry.objects.select_related('blog').get(id=5)

but what is "blog" ?

delgiudices: I think it's because you've modified the signature of __init__ on WPPostModelManager

Paradisee, a blog has entries

Paradisee: Foo.objects.all().select_related('bar')

TheJoey: let me check i think you’re right

Thanks TheJoey it fixed my problem

delgiudices: No problem

How would I serialize multiple models with the rest-framework?

I've found code on how to create a serializer that would do this

But I have no idea how I would actually use it

Kayra: where did you found it?

codeme: http://stackoverflow.com/questions/16429160/how...

ok

TheJoey: i tried select_related, ma i need to grab parent = models.ForeignKey('self', null=True, blank=True, related_name='children') the children

is there a way?

select_related('parent') is fine, cus it is a foreign, but how do i grab children?

Paradisee: Ah, you want to use .prefetch_related() for that. It will execute a second query to retrieve all of the children

im gonna try it.

what software, hosted or cloud, do you use to share passwords amongst team members?

I'm getting a CSRF verification failed. Request aborted. message trying to use a generic formview

nownot: I use LastPass

TheJoey: cost ?

nownot: https://lastpass.com/enterprise/enterprise-pric...

meh, $24/user/year

cool, good to know this is an option. thanks

codeme: Don't know if this helps

codeme: http://dpaste.com/24VPZX3

this is the view https://dpaste.de/UKQZ this is the template https://dpaste.de/A4Rg and this is the form https://dpaste.de/cvWF

what am I doing wrong?

Kayra: so are you using Django Rest Framework?

codeme: don't know what I'd pass in so it works

codeme: Yes

also I'm using jinja

msl09: {% csrf_token %} won't quite work in Jinja.

msl09: Use this instead: <input type="hidden" name="csrfmiddlewaretoken" value="{{ csrf_token }}">

TheJoey: I can't find that in jinja documentation

where would I learn that?

actually nevermind

I'm getting the same error

msl09: https://docs.djangoproject.com/en/1.8/ref/csrf/...

<input type="hidden" name="csrfmiddlewaretoken" value="">

the value is being set to empty

msl09: You do have the csrf middleware enabled, right?

well it's in the settings

msl09 pretty sure your Super() call is incorrect

msl09: Also, is this Django 1.8, using django.template.backends.jinja2.Jinja2, or something else?

let me see

'BACKEND': 'django_jinja.backend.Jinja2',

here is the settings https://dpaste.de/1H3c

msl09: Also, delizin may have a point. return super(ContactView, self).form_valid(form) -- shouldn't that be LoginCacheView instead of ContactView?

I already fixed that, thanks

giarc's point for that one

it didn't solve the problem

Oh, right :)

Kayra: try to follow like this code: http://dpaste.com/324SCDF

Oh, you're not using Django's built in CSRF protection

I think the exception is being thrown before the error happens

msl09 did you try TheJoey's jinija csrf fix after the Super fix?

jinja*

giarc: do you mean django.template.backends.jinja2.Jinja2?

codeme: I understand that bit but then how do I initialise it

msl09: I think the problem is that django-session-csrf doesn't have built-in Jinja2 support. You may be able to refer to {{ request.csrf_token }} to get the right one.

msl09 i meant his template code instead of {% csrf_token %}...but if your not using the built ...

I see

codeme: http://dpaste.com/0K751T2

I'm using the django-allauth package for authentication with github. I have a project deployed to Heroku and I can't set the callback url to https. Anyone know what might cause this?

nah {{ request.csrf_token }} is also empty

I have to wonder, if someone is throwing out django templates and django CSRF protection, how much of Django are they really using?

Then again, I also don’t see a good reason to throw out either of those things, so what do I know.

Okay this is something I have not tried in a while, I'm wanting to save a 'comment' added via form, in my Save def is it comment.save() to start it? there isn't a Comment.create() function or am I forgetting something simple?

save() will be fine.

It will create or update as needed.
