retrieving the ID from a selected drop down list box in ruby on rails

Question

So I have this:

<%= select("selected_red1_robot", "id", @robots.map { |u| [u.team_number,u.id]}) %>

when I do in my controller I see this:

params['selected_red1_robot']

and I see this in my return:

"selected_red1_robot"=>{"id"=>"2"}

I want to do something like:

@roboMatch.robot_id = params['selected_red1_robot']

What am I missing here?

Answer 1

您接近ID，只需按如下所示引用它即可：

@roboMatch.robot_id = params['selected_red1_robot']['id']
