using the below:
<%= select(''project'', ''project_type_id'',
@project_types.collect {|x|
[x.name,x.id]}, {:include_blank => true}) %>
but i''d like that first option to have something like "select
project
type" with an empty value?
Matthew, What you are looking for is the :prompt symbol: http://api.rubyonrails.com/classes/ActionView/Helpers/FormOptionsHelper.html. -- DeLynn Berry delynn@gmail.com http://www.delynnberry.com On 2/19/06, matthew collins <matthewcollins@cfl.rr.com> wrote:> using the below: > > <%= select(''project'', ''project_type_id'', @project_types.collect {|x| > [x.name,x.id]}, {:include_blank => true}) %> > > but i''d like that first option to have something like "select project > type" with an empty value? > > > _______________________________________________ > Rails mailing list > Rails@lists.rubyonrails.org > http://lists.rubyonrails.org/mailman/listinfo/rails >
my apologies, i guess i''m just not getting the syntax down.
i''m trying
<%= select(''project'', ''project_type_id'',
@project_types.collect {|x|
[x.name,x.id]}, {:prompt => "pick something"}) %>
and it''s not showing up?

strange indeed.
<p><label for="project_type">Project
Type</label><br />
<%= select(''project'', ''project_type_id'',
@project_types.collect {|x|
[x.name,x.id]}, {:prompt => "--Select One--"}) %></p>
and on the controller side, i have
@project_types = ProjectType.find_all()
@project = Project.new
ruby -v = 1.8.2
rails -v = 1.0.0

Hmmm, very interesting. I copied your code snippet directly into my app and just changed the @project_types to @users and it worked just fine. Could I see the generated HTML by chance? Is there an item that is being selected? Is it just the first item in the list or is it something else? Does your Project object have a default project type perhaps? What happens if you comment out the "@project = Project.new" bit in your contoller? -- DeLynn Berry delynn@gmail.com http://www.delynnberry.com

Alternatively, you can do: debug(@project_types) in the view to see what it''s set to. But the console is going to let you explore further. -- Jason Perkins jperkins@sneer.org "The computer allows you to make mistakes faster than any other invention, with the possible exception of handguns and tequila."
script/console:
@project_types = ProjectType.find_all()
=> [#<ProjectType:0xb7798a04
@attributes={"name"=>"read",
"id"=>"3"}>,
#<ProjectType:0xb77989c8 @attributes={"name"=>"look",
"id"=>"4"}>,
#<ProjectType:0xb779898c
@attributes={"name"=>"listen",
"id"=>"5"}>]
debug(@project_types)

- !ruby/object:ProjectType
attributes:
name: read
id: "3"
- !ruby/object:ProjectType
attributes:
name: look
id: "4"
- !ruby/object:ProjectType
attributes:
name: listen
id: "5"
and, from another request, the generated html
<!--[form:project]-->
<p><label for="project_type">Project
Type</label><br />
<select id="project_project_type_id"
name="project[project_type_id]"><option
value="3">read</option>
<option value="4">look</option>
<option value="5">listen</option></select></p>
and i''m running this in the test environment on the webrick server.
