I the Admin interface, I need to validate a field which is inside an Inline. Site has a name which has to be stored in lowercase.
How can I access to the name field in the inline to perform that validation?
I could also override its save method in models but I'd like to know how to do it in admin.
class SiteInline(admin.TabularInline):
model = Site
classes = ('grp-collapse grp-open',)
inline_classes = ('grp-collapse grp-open',)
class CompanyAdmin(admin.ModelAdmin):
ordering = ['name']
inlines = (SiteInline, )
