Question

I’m using activeadmin and for whatever reason it’s not like my Tag model. I don’t see anything out of the ordinary about it? google hasnt proved helpful

application_controller

class ApplicationController < ActionController::Base

  protect_from_forgery

  before_filter :get_tags

  private

  def get_tags
    @tags = Tag.all
  end

end

tags_controller

class TagsController < ApplicationController

  def search
    @tags = Tag.where("name like ?", "%#{params[:q]}%")
    respond_to do |format|
      format.json { render :json => @tags.to_json(:only => [:id, :name]) }
    end
  end

  def show
    @tag = Tag.find(params[:id])
    @title = @tag.name
  end

end

tag model

class Tag < ActiveRecord::Base

  self.include_root_in_json = false

  has_many :resource_tags
  has_many :resources, :through => :resource_tags

  attr_accessible :name

  validates :name, :presence => true,
                   :length   => { :within => 2..20 },
                   :uniqueness => { :case_sensitive => false }

end

I’m going to go out on a limb and guess that your Tag model is conflicting with ActiveAdmins
Arbre::HTML::Tag class. There may be other/better solutions, but one thing that’s worked for me in the past is to use the as: option in ActiveAdmin.

ActiveAdmin.register Tag, as: 'AwesomeTag' do

Obviously, the change in copy might be ideal, but it’s a good troubleshooting step. Another option is to rename your Tag model, or try namespacing it.
