Question

我正在处理活动的admin gem。我只是想隐藏仅显示页面的删除链接。所以，我添加了以下代码

ActiveAdmin.register ArticlesSkill do menu :parent => "ReadUp" actions :index, :show, :new, :create, :update, :edit index do column :name, sortable: :name column :description column "" do |resource| links = ''.html_safe links += link_to I18n.t('active_admin.view'), resource_path(resource), :class => "member_link edit_link" links += link_to I18n.t('active_admin.edit'), edit_resource_path(resource), :class => "member_link edit_link" if Article.where(articles_skill_id: resource.id).blank? links += link_to I18n.t('active_admin.delete'), resource_path(resource), :method => :delete, :confirm => I18n.t('active_admin.delete_confirmation'), :class => "member_link delete_link" else # links += link_to I18n.t('active_admin.delete'), "#", :confirm => ("This Skill has A related Article. You Can't Delete This Now"), :class => "member_link delete_link" links += link_to I18n.t('active_admin.delete'), resource_path(resource), :method => :delete, :confirm => I18n.t('active_admin.delete_confirmation'), :class => "member_link delete_link" end links end end end

这是从显示页面删除删除链接，但在索引页面中，如果我尝试删除记录，则显示此错误，

The action 'destroy' could not be found for Admin::ArticlesSkillsController

任何人都可以帮助我吗？请。

Answer 1

所以这是旧的，但我发现自己需要在索引页面和显示页面上有条件地隐藏编辑/销毁按钮，虽然这对我有很大帮助，但我觉得更完整的答案可能会更快地帮助别人。

让我们一起去......

有条件地在索引上显示链接

这个是相对简单的，只是不包括“行动”，而是包括你自己的：

index do
  id_column
  column :name
  column :foo
  column :bar
  column :funded

  # don't do this
  # actions

  # instead make our own column, with no name so it looks like AA
  column "" do |resource|
    links = ''.html_safe
    links += link_to I18n.t('active_admin.view'), resource_path(resource), class: "member_link show_link"
    if !resource.funded?
      links += link_to I18n.t('active_admin.edit'), edit_resource_path(resource), class: "member_link edit_link"
      links += link_to I18n.t('active_admin.delete'), resource_path(resource), method: :delete, confirm: I18n.t('active_admin.delete_confirmation'), class: "member_link delete_link"
    end
    links
  end
end

有条件地在节目上显示按钮

在这里，我们必须从显示页面中删除所有默认按钮，然后添加我们想要的按钮：

# Remove the buttons from the show page
config.action_items.delete_if { |item| item.display_on?(:show) }

# Then add in our own conditional Edit Button
# (note: 'loan' is the registered model's name)
action_item :edit,  only: [ :show ] , if: proc { !loan.funded? } do
  link_to "#{I18n.t('active_admin.edit')} Loan", edit_resource_path(resource)
end

# and our Delete Button
action_item :delete,  only: [ :show ] , if: proc { !loan.funded? } do
  link_to "#{I18n.t('active_admin.delete')} Loan", resource_path(resource), method: :delete, confirm: I18n.t('active_admin.delete_confirmation')
end

# and our (custom) Fund Loan Button
action_item :fund_loan, only: [ :show ], if: proc { !loan.funded? } do
  link_to 'Fund Loan', fund_loan_admin_loan_path(loan), method: :patch
end

# our custom actions code
member_action :fund_loan, method: :patch do
  if resource.fund
    redirect_to resource_path(resource), notice: 'Loan funded'
  else
    redirect_to resource_path(resource), alert: "Loan funding failed : #{resource.errors.full_messages}"
  end
end

希望有助于找到偶然发现此页面的人。快乐编码=]

Answer 2

传递：也销毁到动作方法调用，或传递：全部

actions :all

Answer 3

从ActiveAdmin删除操作的简单方法，例如在控制器中删除

Add totals from field_id=198 for logged-in [userid] if
wp_frm_item_metas field_id=253 where meta_value=Complete
and
wp_frm_item_metas field_id=278 wheremeta_value=Yes
and
wp_frm_item_metas field_id=212 is between Begin and End date
wp_frm_item_metas field_id=270wheremeta_value=[userid of logged in user]

Answer 4

config.action_items.delete_if { |item|
  item.display_on?(:show)
}
action_item only: :show do
 link_to I18n.t('active_admin.edit'), edit_resource_path(resource) end

此代码用于从显示页面中删除操作删除链接，而不是操作。

Answer 5

我已经解决了我的问题。这是一件简单的事情。

只需覆盖你的控制器。

controller do    
  def destroy
    super
  end 
end

仅在activeadmin显示页面中删除删除链接
