我有这样的嵌套路线:
map.resources :foo do |foo|
foo.resources :bar do |bar|
bar.resources :baz
end
end
我在每个资源的索引操作中都有分页列表,我需要缓存每个页面,为此我需要路由是RESTful,我该如何为它实现REFTful路由?
例如我希望路线是这样的:
http://www.example.com/foo/:id/pages/:page_number
http://www.example.com/foo/:id/bar/:id/pages/:page_number

在app / helpers /
中创建custom_link_renderer.rbclass CustomLinkRenderer < WillPaginate::LinkRenderer
def page_link(page, text, attributes = {})
@template.link_to text, "#{@template.url_for(@url_params)}/pages/#{page}", attributes
end
end
将此行添加到config/environment.rb
WillPaginate::ViewHelpers.pagination_options[:renderer] = 'CustomLinkRenderer'

我遇到了同样的问题。我这样编写了自己的LinkRenderer来充分利用嵌套路由。
class PaginationListLinkRenderer < WillPaginate::ViewHelpers::LinkRenderer
protected
def page_number(page)
unless page == current_page
if !@options[:params][:url].to_s.empty?
tag(:li, link(page, @options[:params][:url] + "?page=" + page.to_s))
else
tag(:li, link(page, page, :rel => rel_value(page)))
end
else
tag(:li, page, :class => "current")
end
end
def previous_or_next_page(page, text, classname)
if page
if !@options[:params][:url].to_s.empty?
tag(:li, link(text, @options[:params][:url] + "?page=" + page.to_s, :class => classname))
else
tag(:li, link(text, page, :rel => rel_value(page), :class => classname))
end
#tag(:li, link(text, page), :class => classname)
else
tag(:li, text, :class => classname + ' disabled')
end
end
def html_container(html)
tag(:ul, html, container_attributes)
end
end
然后你必须用这个参数调用will_paginate:
<%= will_paginate :params => { :url => project_task_lists_path(@project) }, :renderer => PaginationListLinkRenderer %>
我希望这会有所帮助:)
