ruby on rails - RailsAdmin doesn't correctly handles belongs_to -

i playing railsadmin on rails 4. , have simple case (two models, event belongs idea).

code:

class idea < activerecord::base end  class event < activerecord::base   belongs_to :idea  end 

schema

  create_table "events", force: true |t|     t.string   "location"     t.integer  "idea_id"     t.datetime "created_at"     t.datetime "updated_at"   end    add_index "events", ["idea_id"], name: "index_events_on_idea_id"    create_table "ideas", force: true |t|     t.string   "title"     t.text     "descrption"     t.datetime "created_at"     t.datetime "updated_at"   end 

and seeing this. , can't figure out why show both drop down choose idea , additional numeric editbox?

.

railsadmin heavily relies on relationships dynamically generate forms. aside that, have encountered other issues down line if didn't map relationships both models.

class idea < activerecord::base   # missing   has_many :events end  class event < activerecord::base   belongs_to :idea end
