django class page view not rendering template code - django

Question

I wanted to use class based views and went through the django documentation and I get noerror messages but wind up with an empty template. I had it working with the non-classed based views. How do I reformat the code so that it renders the template? The template consists of a title, some headings, a navigational menu, flags for selecting instructions in different languages,
followed by a form which shows a flag, policy name char field, and a check box control. I think the initial = {'key': 'value'} in the view forms incorrect but I don't know what to replace it with. Thanks in advance.
forms.py
from django import forms
from policytracker.models import Flag, Label_Links
class PolicyStartForm( forms.Form ):
flags = Flag.objects.all()
policy = Label_Links.objects.all().filter(iso_language='en')[0]
frm_policy1_name=[]
for flag in flags:
frm_policy1_name.append(forms.CharField(max_length=40))
policy_dict = { 'new_policy_link' :policy.nav_section_new_policy_link,
'new_policy_label' :policy.nav_section_new_policy_label,
'graphs_link':policy.nav_section_graphs_link,
'graphs_label' :policy.nav_section_graphs_label,
'account_link' :policy.nav_section_account_link,
'account_label' :policy.nav_section_account_label,
'policy_list_link':policy.nav_section_list_policies_link,
'policy_list_label':policy.nav_section_list_policies_label,
'login_link' :policy.nav_section_login_link,
'login_label' :policy.nav_section_login_label,
'new_policy1_heading' :policy.new_policy1_heading,
'new_policy1_title_label':policy.new_policy1_title_label,
'policy_needs_translation_label':policy.new_policy1_needs_trans_label,
'policy1_submit_label': policy.new_policy1_submit_button_label,
'policy1_tip_msg' :policy.new_policy1_tip_msg,
't_logged_in' :True,
'frm_policy_name' :frm_policy1_name,
't_flags' :flags }

Answer 1

You're using a load of variables in your template, but you aren't actually sending any of them to the context; the only thing your view passes is form. If you want to use things like new_policy1_heading, policy_needs_translation_label and t_flags you need to define them in your view and send them to the template from there.
Actually, it looks like you've completely misunderstood the jobs of forms and views. All the code you've currently put inside your form actually belongs in the view, and you should use policy_dict as the template context. It doesn't look like you need a form class at all.
Even there, though, you're doing much more work than you need to. There's no need to send all the specific fields of the policy object individually; just send policy and then in the template you can do {{ policy.policy_needs_translation_label }} etc.
