{{{
class Parent(models.Model):
uuid = models.UUIDField(primary_key=True, default=uuid.uuid4,
editable=False)
name = models.CharField(max_length=255)
class Child(models.Model):
uuid = models.UUIDField(primary_key=True, default=uuid.uuid4,
editable=False)
name = models.CharField(max_length=255)
parent = models.ForeignKey(Parent)
}}}
{{{
class ChildInline(admin.TabularInline):
model = Child
class ParentAdmin(admin.ModelAdmin):
inlines = [ChildInline]
}}}
== Given the above models and admins: ==
If you attempt to create a {{{Parent}}}, all the {{{Child}}} fields will
contain {{{This field is required.}}} errors.
I think the issue here is {{{default=uuid.uuid4}}}, and I think what's
happening is, since the {{{uuid4}}} value provided to the {{{uuid}}} field
on page load will differ from the {{{uuid4}}} value provided when the form
is posted, Django is considering the state as having been changed
(resulting in validation).
I've set the Component as Forms, since this is most likely a form issue,
rather than being admin-specific. I've also set the Severity to Release
Blocker, since the last {{{UUIDField}}} issue I encountered was marked as
such, and since this sort of breaks the (probably) most common usage of
{{{UUIDField}}}. Please let me know if I should not set the Severity in
the future.
