Drop Down Menu Problem


#1

Here is my papers table:

title:string
duration:integer
exam_at:datetime
paper_id:integer
author:string

and here is my author table:

name:string
email:string
telephone:string
author_id:string

I have created views for both of these table, and I have implemented the
CRUD structure for them both, but there is one small problem I have.
when it comes to creating a new paper, and generating the value for the
author value in the papers table, I want to use a select drop down menu
that consists of the names of all the authors in the authors table (so i
can select which author created the paper).

right now I have the html code displayed like this:

<% form_for(@paper) do |f| %>
<%= f.error_messages %>

<%= f.label :title %>

<%= f.text_field :title %>

<%= f.label :duration %> (Minutes)

<%= f.text_field :duration %>

<%= f.label :exam_at %>

<%= f.datetime_select :exam_at %>

<%= f.label :paper_id %> ID

<%= f.text_field :paper_id %>

<%= f.label :author %>

#AREA OF CODE TO BE FOCUSED ON

<select name=“select”, :author>
Select Author…
<% for author in @authors %>
<%=h author.name %>
<% end %>

#AREA OF CODE TO BE FOCUSED ON

<%= f.submit “Create” %>
<% end %>

Obviously this code will produce a drop down menu that shows the names
of all the authors, but will not save to the table, because it is not
being held by ‘f’. I was just wondering if anybody new the code for this
(should start with “<%= f.select” I believe.

Hope someone can help

I found out.

<%= f.collection_select( :author, @authors, :name, :name, {}, {} ) %>

Just for anyone who may have the same problem at some point
