current_user not available in "visible do" block

[dannybtran]

Not sure if this is the right place to post this but figure I'd try anyway.

I'm trying to implement something similar to this:

RailsAdmin.config do |config|
  config.model Team do
    list do
      field :name
      field :created_at
      field :revenue do
        visible do
          current_user.roles.include?(:accounting) # metacode
        end
      end
    end
  end
end

I know in the README it says the example is theoretical, but I keep getting that current_user is not found within that block. I'm authorizing with CanCan:

RailsAdmin.authorize_with :cancan

At the top of rails_admin.rb in config/initializers

Can anyone tell me how to get current_user available within the visible block? I'd like to only show certain fields in the "List" view if a user is an admin.

Try bindings[:view].controller.current_user or just bindings[:view].current_user

[dannybtran]

bbenezech, thanks for the suggestion. Unfortunately it did not work. I YAML::dump'd the bindings variable in the visible block and it was null, as well as bindings[:view] ... I guess that's only available in the config.edit block?

[sferik]

Assigning @kaapa, since config is his "zone".

Are you sure that 'visible' is the right thing to use? I use 'show' in both the list and edit blocks and it works fine:

  field :active do
    show do
      o = bindings[:object]
      User.current.super? && !o.super?
    end
  end

Fixed meanwhile

I'm still having this exact problem
My devise model is called Admin so I've got:

  config.current_user_method do
    current_admin
  end
  config.model Admin do
    show do
      field :id
      field :email
      field :last_sign_in_ip do
        visible do
          current_user.email == "foo@bar.com"
        end
      end
    end
  end

Which gives me:

undefined local variable or method `current_user' for #RailsAdmin::Config::Fields::Types::String:0x79a0ce4c

Anybody have any ideas?

[bbenezech]

You can call your current_admin or rails_admin's _current_user.

[svoynow]

Both of those result in a similar undefined local variable error ( for _current_user or current_admin, respectively)

bindings[:view]._current_user

[svoynow]

Great, that seems to work. Thanks!
Just out of curiosity, what's actually going on here? Are the other forms
supposed to work? And if so, what should I investigate to figure out why
they're not?

Cheers,

Sasha

_current_user is the RailsAdmin mapping of your current_admin method.
Both are accessible from the view, that you can access in the DSL with bindings[:view]

Cheers!

Does not work in my case:

    list do
      include_fields :id, :title, :body
      field :admin_user do
        visible do
          bindings[:view]._current_user.super_admin?
        end
      end

It gives me
NoMethodError in RailsAdmin::MainController#index
private method `_current_user' called for #RailsAdmin::MainController:0xbeceb94

For show and edit configs this constructions works fine.

[versilov]

But it worked when I used

bindings[:view].current_admin_user.super_admin?

admin_user is my user model name.

[bbenezech]

Shouldn't be private. Use send meanwhile.

[bbenezech]

There is a helper method for _current_user:

https://github.com/sferik/rails_admin/blob/master/app/controllers/rails_admin/application_controller.rb#L16

And there is a test case that passes:

https://github.com/sferik/rails_admin/blob/master/spec/requests/rails_admin_spec.rb#L51

You say it only happens with list, I'm gonna have a look.

[RedXVII]

Hello, The method _current_user is still not public.

config.model 'Model' do
    visible do 
      # this does not work, _current_user is private
      bindings[:controller]._current_user.admin 
    end
end

binding[:view] cannot be used in that scope either.

Thank you
