Ruby on Rails，PublicActivity。未插入外鍵

我正在使用PublicActivity gem創建活動供稿系統。然而，「member_id」永遠不會作爲外鍵插入到「stories：表」中，如果我刪除「belongs_to：member」，系統將會發布，但是當前的member_id永遠不會被插入到控制器表中，您可以看到它永遠不會發送。在member_id作爲一個參數（我下面的教程）Ruby on Rails，PublicActivity。未插入外鍵

而且，我能插入當前member_id到手動表

class Story < ApplicationRecord 

belongs_to :member 

    validates :title, presence: true 
    validates :body, presence: true 

    include PublicActivity::Model 
    tracked 
end 

class Member < ApplicationRecord

...

has_many :stories 

end 

class StoriesController < ApplicationController 
    before_action :find_story, only: [:destroy, :show, :edit, :update] 

    def index 
    @stories = Story.order('created_at DESC') 
    end 

    def new 
    @story = Story.new 
    end 

    def create 
    @story = Story.new(story_params) 
    if @story.save 
     flash[:success] = 'Your story was added!' 
     redirect_to stories_path 
    else 
     render 'new' 
    end 
    end 

    def edit 
    end 

    def update 
    if @story.update_attributes(story_params) 
     flash[:success] = 'The story was edited!' 
     redirect_to stories_path 
    else 
     render 'edit' 
    end 
    end 

    def destroy 
    if @story.destroy 
     flash[:success] = 'The story was deleted!' 
    else 
     flash[:error] = 'Cannot delete this story...' 
    end 
    redirect_to stories_path 
    end 

    def show 
    end 

    private 

    def story_params 
    params.require(:story).permit(:title, :body) 
    end 

    def find_story 
    @story = Story.find(params[:id]) 
    end 

    before_action :load_activities, only: [:index, :show, :new, :edit] 

    private 

    def load_activities 
    @activities = PublicActivity::Activity.order('created_at DESC').limit(20) 
    end 

end

遷移？

你可以打開rails控制檯：'rails c --sandbox'並運行'Story.inspect'？你也可以向我們展示你的'耙路線'嗎？ – DiodonHystrix

Story.inspect =>「Story（id：integer，title：string，member_id：integer，body：text，tags：text，type：integer，category：integer，image_path：string，created_at：datetime，updated_at：datetime）「 – Jay

路由給出了一堆輸出太多，放在這裏 – Jay

如果你想添加current_member ID在故事的表，然後在創建你可以做it.either手動分配@story.member_id = current_member.id或更合適的方法進行，這將是@story = current_member.stories.build(story_params)行動。

如果您需要在故事中添加成員標識（不是current_member標識，而是一個不同的成員），則從視圖發送它。您可以使用hidden_field將member_id作爲參數與其他表單數據一起發送，並將white list發送到故事參數中。

好的，謝謝，目前的行是@ story = Story.new（story_params）如何添加你的（第二）代碼？最引人注目的是「新」標籤 – Jay
