I am new to Django and building a school system but am an experienced
developer otherwise having firm grip over rails, .net, php & java.
I have the following class where on teacher add/edit form, I am trying
to filter values in class drop down based on school. The value of
school_id is saved in session but as you can see below pulling value
from session fails in ModelForm, can someone please guide me on how to
get the value from session here ?
class TeacherForm(ModelForm):
def __init__(self, *args, **kwargs):
super(TeacherForm, self).__init__(*args, **kwargs)
xclass = self.fields['xclass'].widget
choices = []
#school_id = request.session['school_id'] # since this
fails, I have hard coded the value 2 in line below for now
school_id = 2
xclasses = Class.objects.filter(school=school_id)
for c in xclasses:
choices.append((c.id,c.name))
xclass.choices = choices
