How to serialize dictionary in django to render in Jquery [Level of question - Beginner]

Question

The dictionary to serialize - form.errors

e.g. view -

form = PersonalForm(request.POST)
# errors = serializing function which serializes form.errors
data = errors 
#Is this the way to pass data? Not quite sure....
return HttpResponse(data,mimetype="application/json")

e.g. javascript (on success of request) -

function(responseData) {
     $('#errors_form').html(responseData);
                },

Now how do I do this my friends?

It's hard to understand what you are asking? What is the problem? What do you expect and what do you see? — Brian Neal, Mar 19 '11 at 13:57

I still don't understand what you are asking. Did you try it? What did you observe? What did you think should happen but did not? — Brian Neal, Mar 19 '11 at 14:06

import json

data = json.dumps(errors)

return HttpResponse(data,mimetype="application/json")

You're asking how to turn a dictionary into a JSON object, so your jQuery/javascript can read it. json.dumps allows this to happen.

As one "should" search for similar questions before asking, I think one should also search before answering a question :) Your answer is a sub-optimal duplicate of this one -> http://stackoverflow.com/questions/986406/returning-pure-django-form-errors-in-json – Tommaso Barbugli Mar 21 '11 at 11:11

So you're saying I should NOT have answered this question because another person answered a similar question? That does not make sense to me. – Auston Apr 21 '11 at 19:11

You will need to look in two places for errors.

There are "Non field errors":

form.non_field_errors

And field based errors, for example the name field:

form.name.errors

Depending on the complexity of the form, you could reference the errors as individual errors in your json, or make a small python script that combined them. I didn't actually run the code, but think this could work for you:

errors = []
errors = errors + form.non_field_errors

for field in form:
    errors = errors + field.errors

if len(errors) > 0 :
    data = json.dumps({"response_text": "Errors Detected", "errors" : errors})

I think you didn't get my question... the errors itself is not the problem as much as its format... — Sussagittikasusa, Mar 19 '11 at 13:18

Not being picky here but did you actually validate your form ?

form.is_valid()

@Sussagittikasusa - no, form.errors is not populated until you call is_valid(). – Brian Neal Mar 20 '11 at 02:48
