Gentlemen,
I have searched the group and have not found any post that clarifies thsi s=issue to me. Please forgive me in advance if I missed something.
I have 3 models:
Ticket has_many :citations, :dependent => :nullify has_many :violations, :through => :citations
Violation has_many :citations, :dependent => :nullify has_many :tickets, :through => :citations
Citation belongs_to :ticket belongs_to :violation
I am creating the edit a new views for the ticket and would like to be able to relate N violations to the ticket. My intent is to have one select box with a control to add N more if desired. The problem I am running into is getting the select boxes created in a way such that (1) existing items select the correct entry in the select box and (2) when I post the form, Rails recognizes that I am trying to create N relations.
I have tried following examples for a has_many relationship, but it is not working the same.
Following is my current code:
edit.html.erb:
...
<% form_for @ticket do |f| %> <%= render :partial => 'form', :locals => { :f => f } %> <%= submit_tag 'Update Ticket' %> <% end %>
...
_form.html.erb:
...
<%= render :partial => 'violation', :collection => @ticket.violations, :locals => { :f => f, :valid_violations => Violation.find (:all) } %>
...
_violation.html.erb:
...
<%= f.collection_select :violations, valid_violations, :id, :name %>
...
Should I be referencing the citation instead of the violation? I cannot figure out where this needs to go. Please help.
