the line:

@credential.update(credential_params)

throws exception

undefined method 'each' #<user:0x4de4f58>

you need edit associations. have credentials has_many :user , users has_many :credentials. 1 foreign key should belongs_to not has_many. if you're attempting create many-to-many relationship, either utilize has_many_and_belongs_to or bring together table. further, should has_many :users , not has_many :user. should resolve error.
