Rails - WARNING: Can't mass-assign protected attributes

Question

Continuing from here: Rails - Form problems , everytime I try to create a new group_membership I get this: WARNING: Can't mass-assign protected attributes: group, member at my log and the ID's are added blank.

Have been making changes to the attr_accessible of my models but so far no solution.

Thanks in advance.

Answer 1

确保在attr_accessible调用中添加:group和:member :)
