I am working on project in Django 1.8.8 and I need to convert a django form into a JSON format so I can send it to the browser via an AJAX call.
I found this package ( https://github.com/WiserTogether/django-remote-forms ) which is no more available on Pypi. Beside it's 2 years old since the last commit.
Would you please give me some advice on what to do or which package to use ?
Thank you in advance for your help.
The two main things you could do are:
Render the form to an HTML string, and send that.
Create a JSON object, from which the HTML can be constructed.
Here's an example of how you could turn a form object into json:
import json
def form_to_json(form):
result = {}
for name, field in form.fields.iteritems():
result[name] = field_to_dict(field)
return json.dumps(result)
def field_to_dict(field):
return {
"type": field.__class__.__name__,
"widget_type": field.widget.__class__.__name__,
"hidden": field.widget.is_hidden,
"required": field.widget.is_required,
"label": field.label,
"help_text": field.help_text,
"min_length": field.min_length, # optional
"max_length": field.max_length, # optional
"initial_value": field.initial,
}
If you also want to handle error messages server side, you should probably include that information in field_to_dict as well.
To render a form as html, just convert it to a string.
<script>
var data = $("#form_id").serialize()
$.ajax({
type: "POST",
url: url,
data: data,
success: success,
dataType: dataType
});
</script>
I guess... maybe... its really not clear what you are asking
