関連付けを機能させるのに問題があります。
私のモデルは次のようになります。
広告.rb
class Advertise < ActiveRecord::Base
belongs_to :user
belongs_to :country
has_many :targets
# has_many :hss, :through => :targets
validates :description, :presence => true
validates :url, :presence => true
validates :country_id, :presence => true
validates :kind, :presence => true
attr_accessible :description, :hits, :url, :active, :country_id, :kind
KINDS = {
'1' => 'Commoditie',
'2' => 'Service',
}
HS = {
'1' => 'Section',
'2' => 'Chapter',
'4' => 'Heading',
'5' => 'SubHeading 1',
'6' => 'SubHeading 2',
}
end
hs.rb
class Hs < ActiveRecord::Base
attr_accessible :code, :kind
has_many :targets
has_many :advertises, :through => :targets
end
ターゲット.rb
class Target < ActiveRecord::Base
attr_accessible :advertise_id, :hs_id
belongs_to :advertise
belongs_to :hs
end
advertises_controller.rb
def new
@advertise = Advertise.new
@countries = Country.all
end
def create
@advertise = current_user.advertises.build(params[:advertise])
if @advertise.save
flash[:notice] = 'Advertise created with successful'
redirect_to root_path
else
render :new
end
end
form
新しい広告を作成します。
/advertises/new.html.haml
%table.table.table-striped

=fields_for :targets do |target|
%tr
%td= select_tag :hs_kind, options_for_select(Advertise::HS.map(&:reverse).insert(0,'') )
%td= target.select :hs_id, ''
パラメータhash
:
[3] pry(#<AdvertisesController>)> params
=> {"utf8"=>"✓",
"authenticity_token"=>"fOdn4NYLg/4HXruWURZPf9DYVT4EQzbaTRTKZvX1ugY=",
"advertise"=>

ハッシュは問題ないように思えますが、 のみを作成し、関連Advertise
する は作成しません。target
advertise
でも?モデルの関連付けが間違っている可能性があります。
前もって感謝します。
