In Django, I tried using form.errors.as_json() to get all form errors and here is sample json data strings.
{"password2":[{"message": "This password is too short. It must
contain at least 8 characters.","code":"password_too_short"}]}
I wanted to loop and get all under "message" key in json so I can use it to notify the user after ajax call.
Thanks
Anyways, I just resolved my issue and just wanted to share what I did.
views.py
if form.is_valid():
...
else:
# Extract form.errors
errMsg= None
errMsg = [(k, v[0]) for k, v in form.errors.items()]
return JsonResponse(errMsg)
Ajax Event
$.ajax({
method: "POST",
url: '\your_url_here',
data: $form.serialize(),
cache: false,
dataType: "json",
beforeSend: function(){
//Start displaying button's working animation
//Do some button or loading animation here...
}
},
success: function(jResults)
{
//This line is to remove field name display
var strErr = jResults + ''; //make json object as string
strErr = strErr.split(",").pop();
alert(strErr);
}
});
Hope this help to anyone out there facing similar issue. By the way, I'm using Django 2.0 and Python 3.6+
Thanks MinedBP
The correct answer should be:
return HttpReponse(form.errors.as_json(), status=400).
In the AJAX call you can get the content doing:
`$.post("{% url 'your_url'%}", your_payload).done(function(data) {
do_something();
}).fail(function(xhr){
// Here you can get the form's errors and iterate over them.
xhr.responseText();
});`
You are sending a 200 HTTP response, that it is wrong, you should return a 400 HTTP response (Bad request), like Django do without AJAX forms.
