Field.choices get all items as json

[Majid Hojati]

Hi,

I have a Field.choices in my model. lets say it is:

YEAR_IN_SCHOOL_CHOICES = (
('FR', 'Freshman'),
('SO', 'Sophomore'),
('JR', 'Junior'),
('SR', 'Senior'),
)

I can access them using this method Model. YEAR_IN_SCHOOL_CHOICES  but how can I convert it to a json then I can send them using a webservice ? is there any good method?

if you just want to put that into json do:

import json

YEAR_IN_SCHOOL_CHOICES = (

    ('FR', 'Freshman'),
    ('SO', 'Sophomore'),
    ('JR', 'Junior'),
    ('SR', 'Senior'),
)

serialized_year_choices = json.dumps(Model.YEAR_IN_SCHOOL_CHOICES)

In fact I want to convert all of these choises into json format and then send them to user 

thanks

Create a view that returns json.  At least if you want to use it in an ajax way.  Otherwise, I would recommend just passing it as an argument to the templates that use it.

import json

def years(request):

    return HttpResponse(json.dumps(dict(Model.YEAR_IN_SCHOOL_CHOICES)), content_type=‘application/json')

The dict is there to make sure you get it as an object instead of an array of arrays.
