Rails ActiveAdmin：自定义密码重置动作跳转至自定义视图

Hey there! Let's get your password reset action working smoothly with the custom view and ActiveAdmin's default layout. Here's the corrected code and a breakdown of what was adjusted:

Corrected Full Code #

ActiveAdmin.register User do
  # Register the custom route and define the action logic
  member_action :password_reset, method: :get do
    @user = User.find(params[:id])
    # This will automatically render your custom view at app/views/active_admin/users/password_reset.html.erb
  end

  # Add the "Password reset" button to the user edit page
  action_item only: :edit do
    link_to "Password reset", admin_user_password_reset_path(resource)
  end
end

Key Fixes & Explanations #

• Swapped action_view for action_item: action_item is the proper ActiveAdmin method to add custom action buttons to resource pages. We use only: :edit to ensure the button only shows up on the user edit page.
• Added member_action: This registers the custom route for your password reset action (ActiveAuto generates the named route admin_user_password_reset_path automatically). We set method: :get since we're just loading a view page.
• Fixed params[id] to params[:id]: Ruby hash keys require colons for symbols—this was a syntax error that would have broken user lookup.
• Used resource in the link: resource is an ActiveAdmin helper that refers to the current user being edited, so we don't need to manually pass user.id (though admin_user_password_reset_path(user) would also work).

Making the Custom View Work #

Double-check your view file is saved at app/views/active_admin/users/password_reset.html.erb. Since the controller inherits from ActiveAdmin::BaseController, it will automatically use ActiveAdmin's default layout for this view—no extra setup needed! You can add your password reset form or instructions directly in this ERB file.
