I have controller for representing join of Project and User,
joinProjectsUser.
I have added other configuration for like excluding show and search
action in this controller.
When I added following action_link
config.action_links.add 'create', :label => 'Create A New
User',:parameters =>{:controller=>'user'},:page=>true
I get link as expected which take me to new page with form to create
new user. But I get following error message, when I try to save this
new record.
Malformed constraint `Userr#project_id'. If it's a legitimate column,
and you are using a nested scaffold, please specify or double-check
the reverse association name.
ActiveScaffold is passing project_id of Project, which had link for
creation of new User, as a constraint. To satisfy this constraint, it
is searching for column corresponding to project_id in user table.
Since user table does not have any column called project_id, creation
of user fails.
I have added method called 'project_id=' in UsersController, This
method gets called during constraint check with project_id passed to
it as parameter.
Thanks a lot for your help.
