Hi i am trying to figure out what is the best way to do this very basic
lets say i have two tables: one with parents and one with children.
there is a one to many relation between them.
I scaffolded the parents tabel and i can open each parent. Now i want to
add a link to the ‘show’ view which will create a new child record.
In the model i defined the has_many and belongs_to relations between the
children an parents but i dont know what i have to do in the controller
part in order to fill the foreign key field of the child table.
in some example i saw in the controler someting like:
@parent = Parent.find(params[:id])
@child.parent = @parent
but that doesn’t seem to work in my test application, the child saves
but the foreign key is null
on the other hand, if i do
that works but i am not sure that is the way to go, because for that i
don’t have to define the relations in the model, this will work anyway
hope someone can give me some pointers for this very basic question
