Hello,
I am new to rails and have a question about form.select. I
understand the examples that have a select drop down selections which
map to a column in the model’s database row. What I want to do is
provide a drop down list for selections which do not map to a single
column in a row but which maps to any one of the columns in the table.
The list would be defined in the model class, named say Book:
SORT_TYPES = [[“id”, “id”],
[“price”, “price”]
[“color”, “color”]]
The form would look something like:
<% form_for :book, :url => { :action => :sort } do |form| %>
<%= form.select :sort_type,
Book::SORT_TYPES,
:prompt => “sort reviews
by”
%>
<%= submit_tag “Sort”, :class => “submit” %>
<% end %>
When the form is submitted, the sort method of the Book_controller is
called and I want to trap the value the user chose from the drop down
list of options, each of which is a column in the books table. I know
the sort method is called but I can’t seem to get a value from the
selection.
So the question is: How do I trap a value from a form.select which is
not mapped to a single column from a model’s table but to one of the
table’s columns? How about the select return any arbitrary value (one
not associated with a database table)?
Any help would be greatly appreciated.
Thanks for your time,
Dave Hackenyos
