Hi Helpers,
I am new to Ruby in Rails and I have difficulty it
passing the instance varaibles to the view. Earlier I was reading the
values from the table directly in the view. Now I want to do that part in
controller
below is my code before changes
view....
<%= javascript_include_tag :defaults %>
<% form_tag( {:action => 'show'},{:method => :post}) %>
<br><br>
<b>Enter ComponentName
<p>Search for a component to add or move </p>
<% @complist = Components.find(:all, :select => 'DISTINCT
component_name') %>
<%= select_tag "component_name",options_for_select([""]+@complist.map{|u|
[u.component_name]}),:include_blank => true,:onchange =>
remote_function(:url => {:action => :setselectedcomp },:with =>
"'component_name='+value" ) %>
<%= observe_field(:component_name,:controller =>
:comp_groups_controller, :url => {:action => 'select_groups'}, :update =>
:group_names, :with => "'component_name='+value" ) %>
<br>
controller........
def setselectedcomp()
$selected_comp = params["component_name"]
puts "selected_comp: #{$selected_comp}"
$selected_comp_id = Components.find(:all, :select =>
['component_id'], :condition => ["component_name = '#{$selected_comp}'"])
puts "selectd_comp_id is #{$selected_comp_id}"
end
def select_groups
passing_comp = params["component_name"]
puts "passing comp = #{passing_comp}"
@belongstogroup = CompGroups.find(:all, :select =>
['group_name'], :conditions => ["component_name = '#{passing_comp}'"])
belongstogroup.each do |num|
puts num.inspect
end
#return @belongstogroup
render :partial => "select_groups"
end
This is working perfectly fine
What I wanted to accomplish is
1. in the select_tag I have added the "include_blank=true" to allow user
to add a value. it sisn't work for me. May i know what I did wrong
2. I am not getting the component_id value in the controller. Not sure what
I did wrong
$selected_comp_id = Components.find(:all, :select => ['component_id'],
:condition => ["component_name = '#{$selected_comp}'"])
puts "selectd_comp_id is #{$selected_comp_id}"
Appreciate your help on this.
Thanks
Sups
