database design - Edit primary keys in Symfony auto-generated admin -

I have to edit the primary key in several tables.

By default, Simmons hides the primary key in the new / edit form.

For example, the table 'tag' can not be edited with a field 'tag' which is PK. Adding an integer ID in this table is not exactly DB design.

Thank you in advance for your help.

Fields that you can leave alone.
