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.
解决方法
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
