One to many default values

Rails
1

Hi.
I have two tables: users and pens.
the relationship of user and pen is one to many.
In controller, the return value is @pens(all pens belong to a specific
user), but in view, i want to show out all pens’ value as default in
form, how to handle it?

Thank you!

look at options_for_select() and options_from_collection_for_select(),
both of which take a conditional select argument that automatically
“selects” the current value the model has.
