Question

I am trying to change my many to many script field to use FilteredSelectMultiple widget. It works up to validation where it says “Select a valid choice. 12 is not one of the available choices.” and 12 is the right database id for that ResponseAction.

Form:

class ResponseConfigurationForm(ModelForm):
    scripts=forms.ModelMultipleChoiceField(queryset=ResponseAction.objects.all(),widget=FilteredSelectMultiple("ResponseAction",False,attrs={'rows':'5'}))

class Meta:
    model = ResponseConfiguration

Script model:

scripts = models.ManyToManyField('ResponseAction')

I can’t find the problem.

Answer 1

The problem was that memcached kept some tables in memory and therefor it failed.

Solution remove all tables of the app. Syncdb and restart memcached.
