This is my ajax function:
function ajax_call(call_method,data_to_send) {
logger("function ajax_call. var data_to_send: ");
logger(data_to_send);
$('.clickable save_button').hide()
$.ajax({
type: 'POST',
url: call_method,
data: data_to_send,
success: function(data){
logger("data returned to page after ajax call: ");
logger(data);
$('.error_msg').html("Successfully saved record to database.");
$('.error_msg').fadeIn('slow');
setTimeout("$('.error_msg').fadeOut('slow');",5000); // 5 secs to give user enough time to read
$('.clickable save_button').show()
response_dispatcher(data); // This should contain object type at least
},
failure: function(){
$('.error_msg').html("There was an error while saving this information. Please try again. " +
"If the error persists, please contact us using the contact form.");
$('.error_msg').show;
$('.clickable save_button').show()
},
dataType: 'json'
});
}
And, this is the data sent to my method on the backend: { 'display_order':"3", 'goal':"dummy goal", 'id':-1, 'object_type':"goal" }
I've verified within my application that this same data is received.
Here is my Django view method:
@login_required
def update_goal_view(request):
if request.method == 'POST' and request.is_ajax:
# Example data sent from AJAX Request
#qd = {u'display_order': [u'23'], u'object_type': [u'goal'], u'goal': [u'dummy goal'], u'id': [u'-1']}
qd = request.POST
goal = qd.get('goal','')
display_order = qd.get('displ开发者_运维问答ay_order',99999)
id = int(qd.get('id',''))
object_type = qd.get('object_type','')
# For now, just return something to test populating data to the page
id = '100'
goal = 'goal returned'
object_type = object_type
data = {'id':id,'goal':goal,'object_type':object_type}
return HttpResponse(data,mimetype="application/json")
In Firebug, I see this after the ajax call:
POST http://127.0.0.1/xml/update_goal 200 OK 12ms
The issue is, when that it appears that my success callback is never called... I say that because as you can see from above, I there should be a message written to my logger but there isn't one. I know my logger works because of all the other messages outside of the callback that do get written to my logger.
I don't think Django does automatic serialization for dictionaries. You'll have to serialize them to JSON by hand.
import simplejson
# ...
return HttpResponse(simplejson.dumps(data), mimetype="application/json")
You don't show the code that triggers the ajax_call
function. If it's as part of the onclick
event for a submit button, or the onsubmit
event for a form, the usual cause is that you've forgotten to prevent the form from submitting normally - so the page refreshes and the Ajax call is lost.
Use event.preventDefault()
in your event handler to fix this.
