自定义activeadmin的布局（组件）

Activeadmin布局不仅仅是一个文件，它是一个组件集合。

如何使用activeadmin覆盖某些组件，如徽标，导航。

Answer 1

activeadmin布局组件非常容易定制。 您需要做什么：只需定义一个打开ActiveAdmin :: View的模块。

您可以在初始化程序或管理目录中具有custom_activeadmin_components.rb，您可以在其中定义所有activeadmin资源。 我更喜欢将它放在activeadmin资源所在的目录中。 然后覆盖您想要的任何模块：

这是一个示例：

module ActiveAdmin module Views class Header < Component def build(namespace, menu) super(:id => "header") @namespace = namespace @menu = menu @utility_menu = @namespace.fetch_menu(:utility_navigation) build_site_title build_global_navigation build_utility_navigation #you can add any other component here in header section end def build_site_title render "admin/parts/logo" end def build_global_navigation render "admin/parts/main_nav" end def build_utility_navigation render 'admin/parts/language_options' insert_tag view_factory.global_navigation, @utility_menu, :id => "utility_nav", :class => 'header-item tabs' render 'admin/parts/branch_in_header' end end module Pages class Base def build_page_content build_flash_messages div :id => :wizard_progress_bar do render 'admin/parts/wizard_progress_bar' end div :id => "active_admin_content", :class => (skip_sidebar? ? "without_sidebar" : "with_sidebar") do build_main_content_wrapper build_sidebar unless skip_sidebar? end end end end end end 

Answer 2

您可以在admin / your_model.rb文件中自定义活动管理页面。

活动管理员的示例代码如下。

 ActiveAdmin.register User do menu :label => "Our User", :priority => 3 #rename menu & set priority# #for index page# index :title => 'Our User' do #set page title# # index :download_links => false do selectable_column column :title column :category do |e| #want to change name of category e.categoryone end column :address default_actions#this will add default action ie show|edit|delete# end #end index# #for controller# controller do actions :all, :except => [:edit, :new] # you can decide which all methods to be shown in show page. end #end controller# #show start page# show do |user| h3 "User Details" attributes_table do row :title row :description row :address, :label=>"User Address" #overide address label row :country row :approval end h3 "Activity Photoes" attributes_table do user.uploads.each do |img| #call associated model. Here i want to display uploaded image of upload.rb file row(" ") do link_to image_tag(img.to_jq_upload['small_url']), admin_upload_path(img)#here i have added upload module to admin thats yi can directly give path to the upload record of admin module# end end end active_admin_comments # to show comment block of active admin end #show end# #filer(search) start righthand side panel# filter :title filter :category filter :address #end filter# #for menu on show page# action_item only:[:show] do # this add "Approve User" button on the right hand side of show menu only as we have specified only show method if User.find(params[:id]).approval == true link_to "Approve User", approv_user_path(:id => params[:id])#call custom method of normal rails controller# end end #end menu# #start add side bar on page# sidebar "Project Details" do ul do li link_to("Profile", new_project_path) end end #end side bar#
