    <p>I'm trying to update multiple records. The form generates fine and submits fine and the data is sent. The records are looked up to update, but no data is ever saved. I have my controller logic, form logic and console dump below. I'm trying to duplicate what Anthony Lewis <a href="http://anthonylewis.com/2011/04/15/editing-multiple-records-in-rails/" rel="nofollow">put together</a> but I have a feeling I am not passing the right data into or defining correctly the <code>params.require().permit()</code> method. Thanks in advance for your help!</p> <pre><code>class ConfigController &lt; ApplicationController def edit @services = Service.all end def update params["service"].keys.each do |id| @service = Service.find(id.to_i) @service.update_attributes!(service_params) end redirect_to config_url end private def service_params params.require(:service).permit(:id, :client_id, :client_secret) end end </code></pre> <p>Form code is:</p> <pre><code> &lt;%= form_for :service, :url =&gt; update_config_path, :html =&gt; { :class =&gt; "form-horizontal", :method =&gt; "put", :remote =&gt; true } do %&gt; &lt;% @services.each do |s| %&gt; &lt;%= fields_for "service[]", s do |service_field| %&gt; &lt;fieldset&gt; &lt;legend&gt;&lt;%= s.name %&gt;&lt;/legend&gt; &lt;div class="form-group"&gt; &lt;%= service_field.label :client_id, "Consumer Key", :class =&gt; "col-sm-2 control-label" %&gt; &lt;div class="col-sm-10"&gt; &lt;%= service_field.text_field :client_id, :class =&gt; "form-control" %&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class="form-group"&gt; &lt;%= service_field.label :client_secret, "Consumer Secret", :class =&gt; "col-sm-2 control-label" %&gt; &lt;div class="col-sm-10"&gt; &lt;%= service_field.text_field :client_secret, :class =&gt; "form-control" %&gt; &lt;/div&gt; &lt;/div&gt; &lt;/fieldset&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;%= submit_tag %&gt; &lt;% end %&gt; </code></pre> <p>Console reads:</p> <pre><code>Started PUT "/config" for 127.0.0.1 at 2013-11-22 15:44:08 -0800 Processing by ConfigController#update as JS Parameters: {"utf8"=&gt;"✓", "service"=&gt;{"1"=&gt;{"client_id"=&gt;"testid", "client_secret"=&gt;"testsecret"}, "2"=&gt;{"client_id"=&gt;"testkey", "client_secret"=&gt;""}, "3"=&gt;{"client_id"=&gt;"", "client_secret"=&gt;""}}, "commit"=&gt;"Save changes"} Service Load (0.3ms) SELECT "services".* FROM "services" WHERE "services"."id" = $1 LIMIT 1 [["id", 1]] Unpermitted parameters: 1, 2, 3 (0.1ms) BEGIN (0.1ms) COMMIT Unpermitted parameters: 1, 2, 3 {} Service Load (0.2ms) SELECT "services".* FROM "services" WHERE "services"."id" = $1 LIMIT 1 [["id", 2]] Unpermitted parameters: 1, 2, 3 (0.1ms) BEGIN (0.1ms) COMMIT Unpermitted parameters: 1, 2, 3 {} Service Load (0.2ms) SELECT "services".* FROM "services" WHERE "services"."id" = $1 LIMIT 1 [["id", 3]] Unpermitted parameters: 1, 2, 3 (0.1ms) BEGIN (0.1ms) COMMIT Unpermitted parameters: 1, 2, 3 {} Redirected to http://localhost:3000/config Completed 302 Found in 6ms (ActiveRecord: 1.1ms) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
