New description:
With just models.py and admin.py, I was able to save a poll without any
problems.
But if you add onClick="this.disabled=true; this.form.submit()", even if
you try to add qn to the poll, it will not get saved
submit_line.html
{{{
{% if show_save_and_continue %}<input onClick="this.disabled=true;
this.form.submit();" type="submit" value="{% trans 'Save and continue
editing' %}" name="_continue" />{% endif %}
}}}
models.py
{{{
from django.db import models
class Question(models.Model):
qn = models.CharField(max_length=200)
def __unicode__(self):
return self.qn
class Poll(models.Model):
name = models.CharField(max_length=200)
qn = models.ManyToManyField(Question)
}}}
admin.py
{{{
from django.contrib import admin
from .models import *
class PollAdmin(admin.ModelAdmin):
filter_horizontal = ('qn',)
admin.site.register(Poll, PollAdmin)
admin.site.register(Question)
}}}
