I want to override the form of the Matriline
model shown below.
First I add an extra field clan
, and in on_form_prefill
I reset this field's choices and default (just testing).
Without calling form.process
the choices are set to my new options, but the default option is not selected.
If calling form.process
the choices are set to my new options and the default option is selected, but all the other fields are deleted.
Anybody can help?
views.py
class MatrilineAdmin(sqla.ModelView):
form_extra_fields = {
'clan': SelectField('Clan',
coerce=int,
choices=[ (c.id, c.name) for c in Clan.query.all()])
}
create_template = 'admin/create.html'
edit_template = 'admin/edit.html'
def on_form_prefill(self, form, id):
form.clan.choices = [(1, "first"),(2,"second")]
form.clan.default = 2
form.process() # if commented, set choices but does not set default
# else set choices and default but delete all the other fields values (name and pod_id)
