Django request.GET to display value of form field

Question

Is there a way that i can access the values in my form fields before submitting the form.

I need to store the value of one of my fields in request.session[] so as to access it later ( in the same view). I tried doing it using request.GET but it always none.

request.GET.get('name')

where name is the field in a model.

Update

I want to store the value of the form field which is random value generated every time the form is displayed. My models.py contains a random() method which is the default value of the field.

I want to store the field value in sessions, so that i can get the same field value after i return to the page after navigating a few more pages from that page

This is what i was doing:

Django request.session does not resolve

Answer 1

First of all careful when using random in models:

Random/non-constant default value for model field?

Once this is clear I suppose you initialise the form in the view, is there that you need to access the form and get the value for put it in session. For example

form = MyModelForm();
request.session['your_session_key'] = form.data['field_name']

As far as I understand in some cases you want to set this value in the form from the session instead, for do that you can use the initial data as described here.

Hope this helps
