We have the following forms and we are trying to create list of GroupRoleForms
for each group.
class FullNameMixIn():
full_name = TextField(
'Full name', [
validators.required(message=u"Full name is required")
])
class GroupRoleForm(Form):
group =BooleanField('Group', default=False)
role = SelectField(
'Role',choices=[
("none", "----------"),
('approver', 'Approver'),
('editor', 'Editor')
])
class AdminEditUserForm(Form, FullNameMixIn):
group_roles = FieldList(FormField(GroupRoleForm))
How can we create a AdminEditUserForm
instance that contains a pre-populated list of GroupRoleForms
?
At the moment we are trying to do it this way:
form = forms.AdminEditUserForm()
for group in company.groups:
group_role_form = forms.GroupRoleForm()
group_role_form.group.label = group.name
group_role_form.group.name = group.id
form.group_roles.append_entry(group_role_form)
return dict(edit_user_form = form )
In your data
or formdata
keyword arguments for the Form
you just need an dictionary with a key
that matches the FieldList
subfield that contains an iterable. The items in that iterable need in turn have items w/ attributes that match with FieldList
's list of fields.
If you follow the example below I get nested Forms that are pre-populated just fine.

role = SelectField(
'Role',choices=[
("none", "----------"),
('approver', 'Approver'),
('editor', 'Editor')
])
class AdminEditUserForm(Form, FullNameMixIn):
group_roles = FieldList(FormField(GroupRoleForm))
# create some groups
Group = namedtuple('Group', ['group', 'role'])
g1 = Group('group-1', 'none')
g2 = Group('group-2', 'none')
# drop them in a dictionary
data_in={'group_roles': [g1, g2]}
# Build form
test_form = AdminEditUserForm(data=MultiDict(data_in))
# test print
print test_form.group_roles()
