Re: JSONField: which app to choose ?
Hi Matt,
Correct, using either null=True or blank=True on the field works.
However, I don't get it since I didn't click on "save", I just wanted to
display the add page containing it. Why does it attempt to validate the
field at this time and not wait for the form to be sent ? Maybe this is how
Django works ?
Whatever, I think you can set a default value in the JSONField to avoid the
error, what do you think ? I think it's handy.
improvement:
def __init__(self, *args, **kwargs):
kwargs['default'] = kwargs.get('default', '{}')
super(JSONField, self).__init__(*args, **kwargs)
It works for me.
Another point: it does not like "extra" comma right ?
{
"nodes": { "title": "title"*,* }
}
But I guess this is wanted because JSON does not allow it ?
Michael

Re: JSONField: which app to choose ?
Michael,
I've been able to reproduce it: I'm not quite sure of the best way to deal
with it.
One solution is to set either null=True, or blank=True on the field, or set
a default.
The trick is, an empty string isn't valid JSON. I guess I've always been
using a default (usually of {} or [], depending upon context).
Happy for you to suggest improvements, though.

Re: JSONField: which app to choose ?
Hi Michael.
It should 'just work' in the admin: I'm using it fairly extensively, and
most of our access is through the admin (or a JSON api).
If we can get a minimal failing test, then I'll make sure it gets fixed.
(And thanks, Reinout, for the referral/comment)
Matt.

Re: JSONField: which app to choose ?
Can you get it work in the admin ?
I don't understand why I get a ValidationError "[u"'' is not a valid JSON
string."] as soon as I try to reach the Add admin page of my Model...
import jsonfield
class Mapping(models.Model):
data_map4 = jsonfield.JSONField()
-
class MappingAdmin(admin.ModelAdmin):
fields = ['data_map4']
list_display = ('data_map4',)
Thanks.
