我有一個問題,有關嵌套歸因和強大的Rails 4參數。我有一個Property
模型,嵌套與Status
模型,但每個屬性只有has_one
狀態。問題是,當我添加/更新屬性時,屬性被更新,但不是狀態。看看服務器日誌,似乎Rails創建了狀態模型,但決定只添加/編輯property_id
(外鍵),created_at
和updated_at
字段。這裏是日誌說明一點:嵌套屬性強參數只更新外鍵,created_at和updated_at?
SQL (0.3ms) INSERT INTO "statuses" ("created_at", "property_id", "updated_at") VALUES (?, ?, ?) [["created_at", Sat, 11 Jan 2014 16:03:21 UTC +00:00], ["property_id", 9], ["updated_at", Sat, 11 Jan 2014 16:03:21 UTC +00:00]]
(1.4ms) commit transaction
注意沒有未經許可...消息出現。
我確定它不是模型相關的問題,因爲我試圖在控制檯和property.save
工作中執行相同的操作。這就指向了與強參數有關的方向。
任何想法?
這裏是我的代碼: 型號/ property.rb
class Property < ActiveRecord::Base
has_one :status, dependent: :destroy
accepts_nested_attributes_for :status
end
控制器/ properties_controller.rb
def create
@property = Property.new(property_params)
@property.build_status
if @property.save
redirect_to @property, :notice => "Property created successfully."
else
render :action => 'new'
end
end
private
def property_params
params.require(:property).permit(:name,
:address_line1, :address_line2, :address_city, :address_county, :address_postcode,
:structure_Notes,
status_attributes: [:id, :letting_start_date, :process, :comission, :check_in_date, :check_out_date, :notes])
end
感謝您的閱讀! :)
更新:
的PARAMS過去到服務器的數據包括:
Parameters: {"utf8"=>"✓", "authenticity_token"=>"cotr1JZPxPEKga4QbGiFMrEgM5D+UpAzZxEImW5iJvc=", "property"=>{"name"=>"Test Status Again", "address_line1"=>"", "address_line2"=>"", "address_city"=>"", "address_county"=>"", "address_postcode"=>"", "status_attributes"=>{"letting_start_date"=>"2013-01-01", "process"=>"Promoting", "commission"=>"", "check_in_date"=>"", "check_out_date"=>"", "notes"=>"fgjkhsdfkjgh sfjgh sdfhg lskdg"}}, "commit"=>"Create Property"}
這些參數看起來像傳遞給控制器的參數是什麼?你會在日誌中找到這些。 – CDub
數據包含在params中。我會在上面的帖子中更新它。 – Quin
