So what I have is a table called HHActiveCarrier with three columns, an
"Name", "ID", and "Country". Each row in the table is a carrier. I'm
trying to make something that lets you update the country of each
carrier all at once. I went back in my code and changed a bunch of
stuff.
My controller is still generally the same. I'm going to leave the code
in ActiveCarrierController.index the same for now.
Here is what I have now:
class ActiveCarriersController < ApplicationController
def index
@carriers = HhActiveCarrier.find(:all)
for carrier in @carriers
country = carrier["country"]
if country.nil?
carrier["country"] = "none"
end
end
@countries = ["USA", "UK", "Canada"]
end
def update
redirect_to( :action => "index" )
end
end
This is what my form looks like now:
<table>
<thead>
<tr>
<th><%= "Active Carrier" %></th>
<th><%= "" %></th>
<th><%= "Country" %></th>
</tr>
</thead>
<tbody>
<%= form_tag :action => 'update', :id => params[:id] %>
<% for @carrier in @carriers %>
<% fields_for "carrier[]" do |f| %>
<tr>
<td class="tn"><%= f.text_field :name, :readonly => true
%></td>
<td class="tn"><%= f.hidden_field :id %></td>
<td class="tn"><%= f.select :country, @countries %></td>
</tr>
<% end %>
<% end %>
</tbody>
</table>
<%= submit_tag 'Update' %>
<%= end_form_tag %>
If I make a selection in the drop down list and I click "Update", this
is what my request_parameters look like:
request_parameters: {"commit"=>"Update",
"action"=>"update",
"carrier"=>
{"6"=>{"name"=>"Sprint Nextel", "country"=>"USA", "id"=>"6"},
"7"=>{"name"=>"Verizon", "country"=>"USA", "id"=>"7"},
"2"=>{"name"=>"T-Mobile US", "country"=>"UK", "id"=>"2"},
"4"=>{"name"=>"AT&T", "country"=>"USA", "id"=>"4"},
"5"=>{"name"=>"Sprint Nextel", "country"=>"USA", "id"=>"5"}},
"controller"=>"active_carriers"}
How do I take the data in the request_parameters and update each row in
my database? Thanks.
