Object does not support item assignment error

Question

In my views.py I assign values before saving the form. I used to do it the following way:

projectForm.lat = session_results[\'lat\']
projectForm.lng         


        

Answer 1

Another way would be adding __getitem__, __setitem__ function

def __getitem__(self, key):
    return getattr(self, key)

You can use self[key] to access now.

Answer 2

The error seems clear: model objects do not support item assignment. MyModel.objects.latest('id')['foo'] = 'bar' will throw this same error.

It's a little confusing that your model instance is called projectForm...

To reproduce your first block of code in a loop, you need to use setattr

for k,v in session_results.iteritems():
    setattr(projectForm, k, v)
