Rails - Apr 2005 - Getting multiple values from <SELECT> into @params?

Hi,

I''m trying to get multiple selected values from a <SELECT> tag
into @params,
but I can only get the first value in. This my code, something wrong with 
it?

<select name="job[techs]" size="5" multiple>
<%= options_from_collection_for_select(@techs, "id",
"full_name", @
job.technician.collect { |t| t.technician_id.to_i }) %>
</select>

Thanks,

Vincent.

Are you using XHTML?  try multiple="multiple" instead of just the
single attribute ''multiple.''

In PHP, this would be solved by putting [] at the end of the field name, e.g.:

<select name="job[techs][]" size="5"
multiple="multiple">

This causes the selected values to be treated as an array. I have a feeling it
will be the same for Rails.

i believe to get multiple value params you use @request.params instead
of @params.  @params will always only give you the first one.

No need to do that.  Just call your parameter something with [] on the
end.  That way rails knows it''s multiple.

i.e if you call it blah[] then @params["blah"] yields an Array.
