Rails分页嵌套路线

Question

I am attempting to put a contacts paginated partial inside of a view for rooftops . Rooftops has many contacts and also has a nested route allowing /rooftops/1/contacts . When I try to create the will_paginate links I get /rooftops/1 as the path rather than '/rooftops/1/contacts/'.

Is there a way to modify the pagination path with out creating my own pagination link view? I have tried going to the rdoc for will_paginate here but it goes to a godaddy page.

Any ideas?

class Contact < ActiveRecord::Base
  has_and_belongs_to_many :parents
  has_and_belongs_to_many :rooftops
  has_one :user
  has_one :address, :as => :addressable, :dependent => :destroy
  has_many :phone, :as => :phoneable, :dependent => :destroy
  belongs_to :position
  accepts_nested_attributes_for :address, :reject_if => lambda { |a| a[:street].blank? }
  accepts_nested_attributes_for :phone, :reject_if => lambda { |a| a[:phone_number].blank? }, :allow_destroy => true

  validates_associated :address, :phone, :position
  validates_presence_of :lname 
  validates_presence_of :fname 
  validates_presence_of :email 
  validates_presence_of :position_id

  def self.search(page)
    paginate  :per_page => 3,
              :page => page
  end
end

class RooftopsController < ApplicationController
  def show
    @rooftop = Rooftop.find(params[:id])
    @contacts = @rooftop.contacts.search(1)
  end
end

<div class='pagination'>
  <%= will_paginate contacts %>
</div>

This creates /rooftops/1 and I'm not sure how to force it to /rooftops/1/contacts .

---------------------EDIT---------------------

My routes is

resources :rooftops do
  resources :contacts
end

I think I know where my problem is. Since my search function is within the model. I never actually touch the contacts controller. I do the search from the rooftops controller and call a partial from the contacts view. I'll show what my views are.

<div id='contacts' style='margin-top: 20px; border-bottom: 1px solid lightgrey;'>
  <h4>Contacts <%= link_to "new", new_polymorphic_path([@rooftop, Contact]) %></h4>

 <%= render :partial => 'contacts/contacts', :locals => { :object_type => @rooftop, :layer => 1 } %>
</div>

This is the actual partial. As you can see, it never really goes through the contacts controller. Could this be the source of my problem?

<table>
 <tr>
  <th></th>
 </tr>
 <% @contacts.each do |contact| %>
 <tr>
  <td class='contact_mailer'>
   <%= link_to image_tag('icons/gray_light/mail_12x9.png'), "mailto:#{contact.email}" %>
  </td>
  <td>
   <div class='expandable layer_<%= layer %>' style='float: left'>
    <%= link_to contact.fname.titleize + ' ' + contact.lname.titleize, polymorphic_path([object_type, @contact]), :class => "contact_name" %>
      </div>
    </td>
    <td>
      <%= image_tag 'icons/blue/key_stroke_8x8.png' %>
  </td>
 </tr>
 <% end %>
</table>

<br />
<div class='pagination'>
  <%= will_paginate @contacts %>
</div>

Thanks for your help.

There are several places where you could go wrong. Perhaps you don't have your routes set correctly. The will_paginate call should be in the contacts view, it it there? It is not clear from the snippet you gave.

The self.search method in the Contact model is very curious for me, this should be rather in the controller. It makes sense, the search method is related to the control of the Contact . And have it as an instance method.

The route rooftops/:id/contacts should lead to Contact controller. You might check whether it is so.

I suppose you need something like this:

class Contact < ActiveRecord::Base
  # your model definition, validations
  # no self.search method here
  cattr_reader :per_page
  @@per_page = 3
end

class RooftopsController < ApplicationController
  # your RooftopsController methods
  # the show you listed should be in ContactsController
end

class ContactsController < ApplicationController
  def show
    # I guess you have contacts for Rooftop
    @contacts = Rooftop.find(params[:id]).contacts
    # you paginate the array of results
    @contacts.paginate(params[:page])
  end

## This is in the view of the Contacts#show
<div class='pagination'>
  <%= will_paginate contacts %>
</div>

You probably need to paginate on an array. This is simple to do, please refer to this . Hope this helped.
