javascript - AttributeError: 'unicode' object has no attribute 'get' - In Django Forms -

i'm trying use django forms ajax calls.

previously used html form information through request.post['item']. i've been thinking validators, , benefit if switched normal html forms django forms.

in html code (the page user clicks, , ajax calls view javascript):

if not request.user.is_authenticated():     #tells user login if not authenticated      return redirect('/webapp/login.html') else:     #get logger      logger = logging.getlogger('views.logger.chartconfigure')     logger_uuid = uuid.uuid4()     logger_time = datetime.datetime.now()      #log user     logger.info("request in editchart, user:" + str(request.user.username) + ", uuid:" + str(logger_uuid) + ", time:" + str(logger_time))      #forms use     chartname = changechartnameform(auto_id=false)      #put forms context     context = {'chartnameform': chartname}      #return context     return render(request, 'webapp/editchart.html', context) 

the forms used changechartnameform:

#form editing chart names class changechartnameform(forms.form):     #only 1 variable called chartname, label set ""     #since don't want labels. have own in html.     chartname = forms.charfield(max_length=100, label="")     #form-control class required bootstrap 3, , html id     #of form called chartname     chartname.widget.attrs['class'] = 'form-control'     chartname.widget.attrs['id'] = 'chartname' 

html code:

<div class="input-group">     <span class="input-group-btn">         <button class="btn btn-default" type="button" id="newchartname" >new chart name</button>     </span>     {{ chartnameform }} </div> 

the javascript code:

$.ajax( {     type:"post",     url:"ajax_postcolumnaction/",     datatype: 'json',     data:     {         'csrfmiddlewaretoken':csrftoken,         'currenttabselected':currenttabselected,         'currentcolumnselected':currentcolumnselected,         'action':'changename',         'changenameform':$('#chartname').serialize()     },     success: function(response)     {         ...some logic happens here     } } 

basically javascript code call view, called ajax_postcolumnaction:

#get name form, , newname changenameform = changechartnameform(request.post['changenameform']) newname = "" if(changenameform.is_valid()):     newname = changenameform.cleaned_data['chartname'] 

the return always:

'unicode' object not have attribute 'get' @ following line: if(changenameform.is_valid())

i have tried following:

1. using data=request.post
2. using data=request.post['changenameform']

full traceback:

traceback (most recent call last):  file "c:\users\desktop\dropbox (personal)\django\dashboard_web\webapp\views.py", line 738, in ajax_postcolumnaction if(changenameform.is_valid()):  file "c:\python27\lib\site-packages\django\forms\forms.py", line 129, in is_valid return self.is_bound , not bool(self.errors)  file "c:\python27\lib\site-packages\django\forms\forms.py", line 121, in errors self.full_clean()  file "c:\python27\lib\site-packages\django\forms\forms.py", line 273, in full_clean self._clean_fields()  file "c:\python27\lib\site-packages\django\forms\forms.py", line 282, in _clean_fields value = field.widget.value_from_datadict(self.data, self.files, self.add_prefix(name))  file "c:\python27\lib\site-packages\django\forms\widgets.py", line 207, in value_from_datadict return data.get(name, none) attributeerror: 'unicode' object has no attribute 'get' 

edit:

when do:

print request.post['changenameform'] 

i chartname = "some text typed in browser"

this part of error says data unicode string:

return data.get(name, none) attributeerror: 'unicode' object has no attribute 'get' 

data needs object. instead, string, , strings don't have get() method, , don't have name attributes error trace says.

try going off of django docs call ajax:
