    <p>Hi I am trying to use Rails on Rest 2 - movielist tutorial with rails 4 and making adjustments as I go for new rails. I am stuck on associations of Movies Roles. I have added to Movie.rb </p> <pre><code>class Movie &lt; ActiveRecord::Base has_many :roles, :dependent =&gt; :destroy has_many :people, :through =&gt; :roles validates_presence_of :title def new_role=(values) values.each do |i, hash| unless hash[:name].blank? roles.create(:person_id =&gt; hash[:person_id], :name =&gt; hash[:name]) roles.save end end end def deleted_roles=(values) values.each do |role_id| roles.find(role_id).destroy end end end </code></pre> <p>and also to show _Form.html.rb that I render (excert below)</p> <pre><code> &lt;b&gt;Add New People&lt;/b&gt;&lt;br /&gt; &lt;% (1..3).each do |i| %&gt; &lt;%= select_tag 'movie_new_role_person_id', options_for_select(@people), { :name =&gt; "movie[new_role][#{i}][person_id]" } %&gt; &lt;%= text_field_tag 'movie_new_role_name', '', { :name =&gt; "movie[new_role][#{i}][name]" } %&gt;&lt;br /&gt; &lt;% end %&gt; &lt;/p&gt; &lt;p&gt; &lt;%= f.submit "Update" %&gt; &lt;/p&gt; </code></pre> <p>It renders the list to choose from but when i submit - nothing is written to database table. If I manually enter data in database then it displays on movielist page ie: "Stephen Spielberg - Director" etc... Any help appreciated- Driving me nuts at this stage</p> <p>I thought it might be params driven restriction but I do not have a good example of associations style params filter</p> <p>Thanks</p> <p>Alan</p>

    2. COThanks Chicagogrrl . I added that and did what I should have done from the start and debugged the console output more closely. Issue was related to the params as expeted and once I figured out teh syntax for adding methods to params.permits it worked fine. Won;t be making that mistake again so maybe was worth the two days hair pulling. thanks again . I have added teh syntax i used to the answer section in case it is of interest

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.

SQuiL has stopped working due to an internal error.

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