我正在使用带有Rails(3.1.1)的ActiveAdmin(0.4.0)。
我找不到一个很好的方法/ hack来处理多个嵌套资源。
考虑3个模型:
class Program < ActiveRecord::Base
has_many :knowledges, :dependent => :destroy
end
class Knowledge < ActiveRecord::Base
belongs_to :program
has_many :steps, :dependent => :destroy
end
class Step < ActiveRecord::Base
belongs_to :knowledge
end
和ActiveAdmin资源:
ActiveAdmin.register Program do
end
ActiveAdmin.register Knowledge do
belongs_to :program
end
ActiveAdmin.register Step do
belongs_to :knowledge
end
在routes.rb中:
namespace :admin do
resources :programs do
resources :knowledges do
resources :steps
end
end
end
以下是节目索引,知识和步骤的网址:
http://localhost:3000/admin/programs
http://localhost:3000/admin/programs/1/knowledges
http://localhost:3000/admin/programs/1/knowledges/1/steps
“知识”管理员没有问题,但“步骤”管理员不保留嵌套上下文。
例如,当我在步骤#index中使用过滤器时,我被重定向到:
http://localhost:3000/admin/knowledges/1/steps?params ...
但一定是:
http://localhost:3000/admin/programs/1/knowledges/1/steps?params ......
创建新资源时遇到同样的问题:
http://localhost:3000/admin/knowledges/1/steps/new
而不是:
http://localhost:3000/admin/programs/1/knowledges/1/steps/new
面包屑......等同的问题......
到目前为止我在app / admin / steps.rb中尝试了什么:
ActiveAdmin.register Step do
belongs_to :knowledge
config.clear_action_items!
action_item :only => :index do
link_to('Create Step', new_admin_program_knowledge_step_path(knowledge.program.id, knowledge.id))
end
index do
column :id
column :knowledge
column :title
column "Actions" do |step|
link_to("Voir", admin_program_knowledge_step_path(step.knowledge.program, step.knowledge, step), :class => "member_link show_link") +\
link_to("Editer", edit_admin_program_knowledge_step_path(step.knowledge.program, step.knowledge, step), :class => "edit_knowledge member_link edit_link", :id => "knowledge_#{dom_id(knowledge)}") +\
link_to("Supprimer", admin_program_knowledge_step_path(step.knowledge.program, step.knowledge, step), :class => "member_link delete_link", :method => :delete, :confirm => "Delete?")
end
end
filter :id
filter :title
filter :subtitle
filter :stage_type
filter :order_by
filter :created_at
filter :updated_at
form :partial => "form"
end
在app / views / admin / steps / _form.html.erb中我必须使用activeadmin formbuilder:
<%= semantic_form_for(resource, :url => admin_program_knowledge_steps_path(resource.knowledge.program, resource.knowledge), :builder => ActiveAdmin::FormBuilder) do |f|
f.inputs "Step" do
f.input :knowledge, :as => :hidden
f.form_buffers.last << f.template.content_tag(:li, f.template.content_tag(:label, "Knowledge")+f.template.content_tag(:p, f.object.knowledge.title))
f.input :title
f.input :order_by
end
f.buttons
end %>
嗯......我被卡住了。
如何妥善处理?任何线索都赞赏......
答案 0 :(得分:4)
嗯,解决方案非常简单...... https://github.com/josevalim/inherited_resources
ActiveAdmin.register Step do
controller do
nested_belongs_to :program, :knowledge
end
end
