Hi,

Just a heads up for other users:
I've updated from gorm-adapter 3.0.3 to 3.2.0 today and found that NewAdapterByDB() is now using "casbin_rule" as table name vs. "casbin_rules" in 3.0.3.

Therefore the user group memberships where missing in the new "casbin_rule" table.

The reason is probably (didn't verify) the use of the Gorm Migrator in 3.0.3:
return a.db.Migrator().CreateTable(a.getTableInstance())
In Gorm "CasbinRule" will result in a table name "casbin_rules".

This fixed if for me:
insert into casbin_rule(ptype,v0,v1) select p_type,v0,v1 from casbin_rules where p_type = 'g';
