Sorry guys - such an obtuse question, but with all the myriad
possibilities out there for using select statements in my rails
template, I can''t figure out which one is the best. Here''s my
problem: I
have a very simple form, which only does one thing: you select a name to
add to a project, click the submit button, and the form sends two
variables (the id of the name to add to the project (:addpersonid) plus
the id for the project for the redirect back(:id)) to an update function
very similar to the default scaffolding update function.
The names are pulled out of a model (Person), but I want to exclude any
names that are already on the project from the dropdown. Here''s my
pseudocode:
<% form_tag :action => ''update'', :id => @id -%>
<select name="addpersonid">
<% for p in @people -%>
<% unless @team.include?(p) %>
<option value="<%= p.id %>">
<%= p.family_name, :action => "update", :id => @id,
:addpersonid =>
p.id %>
</option>
<% end %>
<% end -%>
<%= submit_tag ''OK'' %>
</select>
<% end -%>
I don''t even know if this will work, but even if it does
there''s got to
be a better way to do this. Anybody got any tips?

Anybody got any tips?Perhaps one way might be <%= select_tag "addpersonid", *options_from_collection_for_select*( (@people - @team), :id, :family_name ) -%> Of course I''m not sure what the :action => ''update'', :id => @id, :addperson_id => p.id is in there for. This should be elsewhere in the form surely.

That was a hasty cut and paste by me. I ended up taking it out after I posted the message. I will try your solution. It looks like the @people - @team part means that you subtract anybody who is in @team from @people, right? Also not sure what those asterisks are doing. But I will look it up in the API if I can find it.

It looks like the @people - @team part means > that you subtract anybody who is in @team from @people, right?Yes. The association collections that AR returns are delegated to Array. So normal array operations mostly work. Also not> sure what those asterisks are doing. But I will look it up in the API if > I can find it.Not sure what asterisks you mean. I don''t see any.

Sorry - maybe they''re only coming up as asterisks in my browser. This is what I see: <%= select_tag "addpersonid", *options_from_collection_for_select*( (@people - @team), :id, :family_name ) -%> In any case, I''ll disregard them.
