Question

我发生了一件奇怪的事情。我有一个模型调用配方has_many：信息和：方向。当我尝试保存@recipe（请参阅我的控制器）时，其中有许多：信息和：方向;有时候它有效，有时它不会在我没有改变任何东西的源代码。

此外，：信息始终保存;问题似乎只是关于：方向

这是我的控制器：

    def new
        @recipe = current_user.recipes.new
    end

    def create
        @recipe = current_user.recipes.new(recipe_params)

        if @recipe.save
            redirect_to @recipe, notice: "Successfully created new recipe"
        else
            render 'new'
        end
    end     
    private

    def recipe_params
        params.require(:recipe).permit(:category_id, :title, :description, informations_attributes: [:id, :title, :url, :_destroy], directions_attributes: [:id, :title, :url, :step, :_destroy])
    end
end

当我尝试从我的表单中保存时，这里是params：

参数：{＆＃34; utf8＆＃34; =＆gt;＆＃34;✓＆＃34;，＆＃34; authenticity_token＆＃34; = GT;＆＃34; WFA + WTI + C3hnvscAC1O922EYlssJE3zAbEmmqMbmR + 5krb0b17fkWhsXVAW1aFcom8x11uGqGO6drQudGhdcvA ==＆＃34 ;, ＆＃34;食谱＆＃34; =＆gt; {＆＃34;标题＆＃34; =＆gt;＆＃34;测试＆＃34;，＆＃34;描述＆＃34; =＆gt;＆＃34;测试＆＃34 ;，＆＃34; category_id＆＃34; =＆gt;＆＃34; 3＆＃34;，＆＃34; informations_attributes＆＃34; =＆GT; {＆＃34; 1431197959831＆＃34; =＆GT; {＆＃34;标题＆＃34; =＆GT;＆＃34;测试＆＃34 ;, ＆＃34; url＆＃34; =＆gt;＆＃34; dede＆＃34;，＆＃34; _destroy＆＃34; =＆gt;＆＃34; false＆＃34;}，＆＃34; 1431197959835＆＃34; = ＆GT; {＆＃34;标题＆＃34; = GT;＆＃34; DED＆＃34 ;, ＆＃34; url＆＃34; =＆gt;＆＃34; dede＆＃34;，＆＃34; _destroy＆＃34; =＆gt;＆＃34; false＆＃34;}}，＆＃34; directions_attributes＆＃34; =＆GT; {＆＃34; 1431197963709＆＃34; =＆GT; {＆＃34;标题＆＃34; =＆GT;＆＃34;德德＆＃34 ;, ＆＃34; url＆＃34; =＆gt;＆＃34; dede＆＃34;，＆＃34; step＆＃34; =＆gt;＆＃34; de＆＃34;，＆＃34; _destroy＆＃34; =＆gt; ;＆＃34;假＆＃34;}，＆＃34; 1431197963712＆＃34; =＆gt; {＆＃34;标题＆＃34; =＆gt;＆＃34; ded＆＃34;，＆＃34; url＆＃34; =＆gt;＆＃34; ded＆＃34 ;，＆＃34; step＆＃34; =＆gt;＆＃34; ded＆＃34;，＆＃34; _destroy＆＃34; =＆gt;＆＃34; false＆＃34;}}}，＆＃34;提交＆＃34; =＆gt;＆＃34;创建主题＆＃34;}

Shema：

  create_table "directions", force: :cascade do |t|
    t.text     "step"
    t.integer  "recipe_id"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.string   "url"
    t.string   "title"
  end


  create_table "information", force: :cascade do |t|
    t.string   "url"
    t.integer  "recipe_id"
    t.datetime "created_at",                            null: false
    t.datetime "updated_at",                            null: false
    t.integer  "cached_votes_total",      default: 0
    t.integer  "cached_votes_score",      default: 0
    t.integer  "cached_votes_up",         default: 0
    t.integer  "cached_votes_down",       default: 0
    t.integer  "cached_weighted_score",   default: 0
    t.integer  "cached_weighted_total",   default: 0
    t.float    "cached_weighted_average", default: 0.0
    t.string   "title"
  end


  create_table "recipes", force: :cascade do |t|
    t.string   "title"
    t.text     "description"
    t.integer  "user_id"
    t.datetime "created_at",  null: false
    t.datetime "updated_at",  null: false
    t.integer  "category_id"
  end

感谢您的帮助！
