Hi
I've made a small change to the ModelForm framework to allow declarative
definition of validators. This allows for quick and easy reuse of
validators and means I have to write less clean_foo methods. This works
both in the admin as in custom views.
What used to be written like this:
class Domain(models.Model):
name = models.CharField(_('Name'), max_length=255, unique=True,
validator_list=[validators.isValidHostName])
active = models.BooleanField(_('Active'), default=True)
Could then be written like this:
class Domain(models.Model):
name = models.CharField(_('Name'), max_length=255, unique=True)
active = models.BooleanField(_('Active'), default=True)
class DomainModelForm(forms.ModelForm):
class Meta:
model = Domain
validators = {
'name': [validators.isValidHostName],
}
And can be used in the admin like this:
from foo.forms import DomainModelForm
from foo.models import Domain
class DomainAdmin(admin.ModelAdmin):
list_display = ('name', 'active')
list_filter = ('active',)
search_fields = ('name',)
form = DomainModelForm
admin.site.register(Domain, DomainAdmin)
Anybody interested in this?
Is it worth opening a ticket with a patch?
Cheers
Steven
