remove delete link only in activeadmin show page

I am working on the active admin gem. I just want to hide the delete link only from show page. So, I added the below code

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

This is removing the delete link from the show page, But in the index page if I try to delete a record, its showing this error, 

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

Any one can help me in this? Please.

Small adjustment to the Ryan answer, for those who do not like using direct strings manipulations:

actions(defaults: false) do |resource|
    item I18n.t('active_admin.view'), resource_path(resource), class: "member_link show_link"

    next if resource.funded?
    
    item I18n.t('active_admin.edit'), edit_resource_path(resource), class: "member_link edit_link"

    item I18n.t('active_admin.delete'), resource_path(resource), 
         method: :delete, 
         confirm: I18n.t('active_admin.delete_confirmation'), 
         class: "member_link delete_link" 
  end

So this is old, but I found myself needing to conditionally hide the edit/destroy buttons on both the index page and the show page, and while this helped me a lot, I felt a more complete answer might help others quicker.

Let's give that a go...

Conditionally Show Links on Index

This one is relatively straightforward, simply don't include the "actions" and instead include your own:

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

Conditionally Show Buttons on Show

Here we'll have to remove all the default buttons from the show page and then add in the buttons we want:

# 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

Hopefully that helps out someone who stumbles upon this page. Happy coding =]

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

Instead of actions this code is used to remove the action delete link from show page.

Simple way to remove action from ActiveAdmin like delete in controller

ActiveAdmin.register User do

     actions :all, except: [:destroy]

end

I have fixed my Issue. It was a simple thing.

Just override your controller.

controller do    
  def destroy
    super
  end 
end

Pass :destroy also to actions method call, or pass :all

actions :all
