Updating a model from a checkbox (noob question)

Rails
1

Hello everyone,

I’m trying to wire a combobox in a view to update the database. When I
select something in the combobox and press ‘update’ it goes through
fine, except it places the default value for the field of the combobox.
Any suggestions?

Here’s the model:

class TestResult < ActiveRecord::Base
has_one :status_index
has_one :test_type
has_one :product_area
validates_presence_of :statusindex_id, :testtype_id, :productarea_id,
:name
end

This generates the combobox (inside a view partial):

<%= select(“test_type”, “id”, TestType.find_all.collect {|tt| [tt.name,
tt.id] }, { :include_blank => false}) %>

Here’s the command in the controller’s ‘update’ method:

@test_result.update_attributes(params[:test_result])

Thanks very much,
Roy T.

@test_result.update_attributes(params[:test_result])

I could be wrong, but based on what you’ve shown us, I’m pretty sure the
result of your select is going to come back to the controller in
params[:test_type][:id], not in params[:test_result]. But I could
definitely be wrong because I don’t have any experience with
using.find’s in
my views.

You might want to use a ‘dummy’ view with <%= params.inspect %> to check
to
see exactly what is coming back.

hth,
