我的blog/_form.html.erb上有一系列复选框，这些复选框使用Javascript / JQuery为hidden_field_tag更新了:subcategory_ids。

隐藏字段如下：

<%= f.hidden_field :subcategory_ids %>

据Google代码检查员说，该值正在更新：

<input type="hidden" value="1,5,6" name="blog[subcategory_ids]" id="blog_subcategory_ids">

我的blog中具有以下schema.rb结构：

 create_table "blogs",force: :cascade do |t|
    t.string "title"
    t.string "teaser"
    t.text "body"
    t.boolean "motivation",default: false
    t.boolean "mindset",default: false
    t.boolean "resourcing",default: false
    t.boolean "planning",default: false
    t.boolean "time_management",default: false
    t.boolean "discipline",default: false
    t.string "image_url"
    t.text "pinterest_description"
    t.boolean "published",default: false
    t.datetime "published_at"
    t.boolean "approved",default: false
    t.boolean "featured",default: false
    t.bigint "user_id"
    t.datetime "created_at",null: false
    t.datetime "updated_at",null: false
    t.string "primary_category"
    t.bigint "resource_id"
    t.string "subcategory_ids",array: true
    t.index ["resource_id"],name: "index_blogs_on_resource_id"
    t.index ["user_id"],name: "index_blogs_on_user_id"
  end

还有我的blogs_controller.rb中的以下参数：

def blog_params
  params.require(:blog).permit(
    :title,:teaser,:body,:primary_category,:motivation,:mindset,:resourcing,:planning,:time_management,:discipline,:image_url,:pinterest_description,:published,:published_at,:featured,:approved,:resource_id,:user_id,:pins => [],:subcategory_ids => []
  )
end

但是，由于服务器中发生subcategory_ids错误，我的unpermitted parameter: :subcategory_ids似乎没有保存：

这很奇怪，因为它表明已编辑的博客确实具有subcategory_ids，但随后又说这是一个不允许的参数。

我已重新启动服务器，但无济于事。谁能看到为什么发生此错误或为什么没有保存该错误？
