jquery - Why does json.dumps() throw a 500 internal server error when using variables? -

i've tested out thoroughly , have no idea why it's doing this, wondering if explain...

json.dumps() throwing 500 internal server error when try use variable instead of string.

for example:

error = 'login failed:  username or password incorrect.' test = json.dumps({'form': error}) 

will return 500 internal server error when attempting return through jquery.ajax

however,

test = json.dumps({'form': 'login failed:  username or password incorrect.'}) 

will not throw 500 internal server error. i've tested out thoroughly single quotes, double quotes, different formatting, etc , points json.dumps()

for reason, occurring when calling view through jquery.ajax

if don't return json.dump() , return normal json object still throws 500 error, why i've concluded it's json.dumps() , not .ajax call **

here's snippet of code i'm using this: unknown reasons.. throw error while calling particular page through jquery.ajax()

yes.. though variable 'test' not being returned.

        elif(password == 'testing_this'):              error = 'login failed:  username or password incorrect.'              errors = true          test = json.dumps({'form': error})         #print test         date = datetime.date.today()          if(errors == true):             return httpresponse(json.dumps({'form': 'error message here'}), mimetype='application/json')         else:             return httpresponse(json.dumps({'result': true}), mimetype='application/json') 

turning debug on in settings, , going through traceback may useful.

just of wall, may assume before check (if(errors == true):) may forgot initialize errors initial value throws nameerror... it's assumption.

upd: sorry ajax part slipped mind - +1 waitinforatrain's comment
