First I don't think you should be using the admin for such fine grained
control of your data formats.
BUT if you do want to do that you would want to do your validation in custom
admin forms. (created in your admin.py to do cleans on the data that's being
submitted)
Second I wouldn't do a manytomany with this, I would instead create an
inline on your userinfo model linking to phones. Then your Phone will have a
FK relationship to your UserInfo.
in models.py
class Phone(model.Models):
number = models.CharField(max_lenth=25)
class UserInfo(model.Models):
name = models.CharField(max_length=50)
in admin.py
from myproject.myapp.models import Phone, User
class PhoneInline(models.TabularInline):
model = Phone
class UserAdmin(models.ModelAdmin):
inlines = [PhoneInline, ]
admin.site.register(User, UserAdmin)
What you get with that is the ability for a user to dynamically add as many
phone numbers to a user as they want. Also you get the charfield (instead of
the select box, which is what you get from the M2M field)
