splitクラスを使用して配列を分割しようとしています。私はこのエラーを受け取り続けます:
MethodError (undefined method `split' for nil:NilClass):
これが私がやろうとしていることです:def create
@listing.landlord = current_landlord
if @listing.save
photo_id_array = params[:images].split(/,/)
photo_id_array.each do |image|
@image = Photo.find_by_id("photo.id")
@image.listing_id = @listing.id
end
render :show, :status => 200
else
render :status => 403, :json => {:errors => @listing.errors}
end
end
Rails3.2.9を実行しています。これを引き起こしている可能性のあるものについてのアイデアはありますか?
