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.
