HELP: array in a database field

i am passing an array of items to the rails create scaffold from a form
(checkboxes) e.g

this works, and when i check my database table the field contains the

  • 1st value
  • 2nd value
  • 3rd value

so when i come to use these values i get the first value which is ‘—’
the second value as ‘- 1st value’ etc… obviously i want the first value
to be ‘1st value’, second value ‘2nd value’ etc.

any body else experienced this, and have a solution??

It looks like you are trying to store the results of an association
(has_many, habtm) in a field on a database table.

For example, if you are saving a user that has many roles, instead of
a “roles” field on your table, you would have a separate roles table and
roles_users table. The models would look like:

User - has_and_belongs_to_many :roles
Roles - has_and_belongs_to_many :users

The view would look like:

<% for role in Role.find(:all) %>

<% end %>

In the controller, on the create/update you use the convenient
method of the user object, like:[:user])
@user.role_ids = params[:role_ids]

Hope that helps.
