Im writing a policy to edit a model. When the index is generated, the definition for the edit method is asked in order to show the button. But when I try to edit the object the variable changes and instead of showing the values of the object it only show the types of the input.

The thing is that I need to know the values of the object to check if I have permission to edit it. When I try to edit this object it checks twice the definition for edit. The first time aproves it, but not the second time and the applicacion crashes.

(Support Request)
I have added the rails_admin? method to the app/policies/application_policy.rb as per the readme but the code seems to want me to add the same/similar method to all other policies I have - eg the ones for different models. It does not see that the application_policy.rb acts as a fall back.

Is this correct behaviour or have I done something wrong?

RailsAdmin basically now has the exact same code but with tests since railsadminteam/rails_admin#2399 has been merged

Update README and recommend using the RailsAdmin pundit authorization extension?

I honestly don't know if this is a bug or an issue with my implementation, but I followed all the instructions and still can't figure out a solution. I'm on Rails 5 and I use pundit with devise.

Here's a snippet of my Gemfile:

gem 'devise'
gem 'devise-i18n'
gem 'rails_admin', '~> 1.0'
gem 'rails_admin-i18n'
gem 'rails_admin_tag_list', github: 'kryzhovnik/rails_admin_tag_list'
gem 'pundit'
gem "rails_admin_pundit", :github => "sudosu/rails_admin_pundit"

And a snippet of my rails_admin initializer:

RailsAdmin.config do |config|
  config.authorize_with :pundit
  config.current_user_method(&:current_user)
  ...
end

My Application policy looks like this:

class ApplicationPolicy
  attr_reader :current_user, :record

  def initialize(current_user, record)
    @user = current_user
    @record = record
  end

  def index?
    false
  end

  def show?
    scope.where(:id => record.id).exists?
  end

  def create?
    false
  end

  def new?
    create?
  end

  def update?
    false
  end

  def edit?
    update?
  end

  def destroy?
    false
  end

    def rails_admin?(action)
        case action
        when :dashboard
            @user.admin?
        when :index
            @user.admin?
        when :show
            @user.admin?
        when :new
            @user.admin?
        when :edit
            @user.admin?
        when :destroy
            @user.admin?
        when :export
            @user.admin?
        when :history
            @user.admin?
        when :show_in_app
            @user.admin?
        else
            raise ::Pundit::NotDefinedError, "unable to find policy #{action} for #{record}."
        end
    end

end

Do you have any idea why this isn't working ? Thanks in advance

ps: I created a question on stackoverflow

thanks for making up this gem, not sure why I am getting this error message

NoMethodError at / undefined method `admin?' for nil:NilClass

my application_policy looks like following.

class ApplicationPolicy
  attr_reader :user, :record

  def initialize(user, record)
    raise Pundit::NotAuthorizedError, "must be logged in" unless user
    @user = user
    @record = record
    Rails.logger.info user
  end

  def index?
    user.admin? or user.staff?
  end

  def show?
    scope.where(:id => record.id).exists? and (user.admin? or user.staff?)
  end

  def create?
    user.admin? or user.staff?
  end

  def new?
    create?
  end

  def update?
    user.admin? or user.staff?
  end

  def edit?
    update?
  end

  def destroy?
    user.admin?
  end

  def rails_admin?(action)
    case action
      when :dashboard
        user.admin?
      when :index
        user.admin?
      when :show
        user.admin?
      when :new
        user.admin?
      when :edit
        user.admin?
      when :destroy
        user.admin?
      when :export
        user.admin?
      when :history
        user.admin?
      when :show_in_app
        user.admin?
      else
        raise ::Pundit::NotDefinedError, "unable to find policy #{action} for #{record}."
    end
  end

end

thanks.

Hi,
Thank you in advance for your software and you efforts.

I am trying to use rails_admin_pundit to add role based access
to rails_admin.

I am getting this error when I click on the users table in the rails_admin.

ArgumentError at /user. User(id: integer, email: string, ... 'shortened' ...role: integer) is not an ActiveRecord::Relation

I created an app using:
https://github.com/RailsApps/rails-devise-pundit

and followed the usage instructions at:
https://github.com/sudosu/rails_admin_pundit

This is in my user_policy.rb just to get things started...

def rails_admin?(action)
  case action
    when :destroy, :new
      false
    else
      @current_user.admin!
  end
end

• I can get pundit to work outside of rails_admin
• I am logged in as admin
• I have googled the web for this error or similar issues.

Can someone help me with this?

Attached are a couple apps with the error, and a screen shot of what I see just before I press the Users model name link.

app with the error..

error file and screenshot

another app with the same error

Not needed: dropbox link...
link to screenshot, error page, and two apps that I have this problem in...

As I see rails_admin have similar extension https://github.com/sferik/rails_admin/blob/master/lib/rails_admin/extensions/pundit/authorization_adapter.rb
Do this gem have any differences from included version, or we should prefer RailsAdmin::Extensions::Pundit from rails_admin?
