acts_as_taggable not populating :tag_list field

[howells]

acts_as_taggable seems to be working correctly everywhere else but activeadmin, and confusingly does work for other models but not one called "PartnerBenefit". So it can only be an ActiveAdmin bug, or something dumb I'm doing wrong.

When words separated by commas are entered into the tag_list field they are parsed and saved successfully, but when I return to edit the PartnerBenefit, the tag_list field is blank (and so saving again just removes the tag associations).

In my aa file:

# form
    form :html => { :enctype => "multipart/form-data" } do |f|
        f.inputs do
            f.input :name
            f.input :title
            f.input :tag_list
            f.input :thumbnail, :as => :attachment, :required => false,
                :image => proc { |o| o.thumbnail.url(:main) if o.thumbnail.present? }
            f.input :header_image, :as => :attachment, :required => false,
                :image => proc { |o| o.header_image.url(:main) if o.header_image.present? }
            f.input :description, :as => :ckeditor
            f.input :details, :as => :ckeditor, :hint => "Shown only to super members"
            f.input :position
        end
        f.actions
    end

IN my model:

class PartnerBenefit < ActiveRecord::Base

    attr_accessible :description, :name, :position, :thumbnail, :title, :details, :header_image, :summary, :tag_list

    acts_as_list

    default_scope order("position")

    has_attached_file :thumbnail,
            :styles => { :main => '220x226#' }
    do_not_validate_attachment_file_type :thumbnail

    has_attached_file :header_image, :styles => { :thumbnail => '100x100#', :main => ['700x315#', :jpg] }
    do_not_validate_attachment_file_type :header_image

    acts_as_taggable

    def to_s
        title
    end

    def to_param
        "#{id} #{name}".parameterize
    end

end

Any ideas?

please do this in your active admin resource:

controller do
  def update
    super
    puts @partner_benefit.inspect
    puts params
  end
end

I’m going to close this since you haven’t responded. Please feel free to update this issue with additional information so it can be reconsidered.

Sorry for the epic delay on this - I added that in but what should I expect to see?

[timoschilling]

After 2 month, I don't know why I ask that. Please Post that result and I reopen the issue and take a look on it.

It seems that the tags are committed correctly on update, and if I just use

f.input :tags

a multiple select box with the correct tags is shown; it's just the tag_list method that seems to be blank
