the error is :

ERRORS: <class 'registerapp.admin.UserAdminConfig'>: (admin.E012) There are duplicate field(s) in 'fieldsets[1][1]'. <class 'registerapp.admin.UserAdminConfig'>: (admin.E012) There are duplicate field(s) in 'fieldsets[2][1]'.

btw I have to inform that I have used mobileNumber as unique=True in my model

CodePudding user response：

As error say, you have duplicate fields in fieldsets. First fieldset "None" has "name" and "familyName", second fieldset "User Information" has "name" and "familyName" again.

Try removing "name" and "familyName" from first or second fieldset
