Django Tastypie Deserializing Multipart/Form-Data To Upload File -

i trying upload files via multipart/form-data form , tastypie api , running issues:

my model:

class client(models.model):     account = models.foreignkey(account)     client_image = models.filefield(upload_to=client_image_path, default="/assets/img/default-user-image.png", blank=true, null=true)     client_image_thumb = models.filefield(upload_to=client_image_thumb_path, default="/assets/img/default-user-image.png", blank=true, null=true) 

i using custom deserialize method outlined in tastypie issue#42:

class multipartresource(object):     def deserialize(self, request, data, format=none):         if not format:             format = request.meta.get('content_type', 'application/json')          if format == 'application/x-www-form-urlencoded':             return request.post          if format.startswith('multipart'):             data = request.post.copy()             data.update(request.files)             return data          return super(multipartresource, self).deserialize(request, data, format)      def put_detail(self, request, **kwargs):         if request.meta.get('content_type').startswith('multipart') , \                 not hasattr(request, '_body'):             request._body = ''          return super(multipartresource, self).put_detail(request, **kwargs) 

and here corresponding modelresource:

class clientresource(multipartresource, modelresource):     account = fields.foreignkey(accountresource, 'account')      class meta():         queryset = client.objects.all()         always_return_data = true         resource_name = 'account/clients/client-info'         authorization = accountlevelauthorization()         list_allowed_methods = ['get','post','put','delete','patch']         detail_allowed_methods = ['get', 'post', 'put', 'delete','patch']         authentication = apikeyauthentication()         filtering = {             'username': all,         } 

if post content-type application/json , dont include client_image field, create new client object. indicates models/resources working should.

however, when try use multipart/form-data content type can see gets through deserializer appropriately payload:

------webkitformboundaryp0q7q9djlsvvgwbb content-disposition: form-data; name="{%0d%0a%22account%22"  "/api/v1/account/account-info/21/",  ------webkitformboundaryp0q7q9djlsvvgwbb content-disposition: form-data; name="client_image"; filename="donavan.jpg" content-type: image/jpeg  ------webkitformboundaryp0q7q9djlsvvgwbb-- 

i seeing querydict while debugging, shows inmemoryuploadedfile correctly:

<querydict: {u'client_image': [<inmemoryuploadedfile: donavan.jpg (image/jpeg)>], u'{%0d%0a%22account%22': [u'"/api/v1/account/account-info/21/"']}> 

but keep getting error:

any ideas broken? in advance!

this happened me when post data without providing necessary fields. fields cannot null must provided while posting.
