ruby-on-rails – Rails – 在视图中渲染视图 – 传递参数

<%= link_to( tag.content,[object,tag],method: :patch) %>

如果我想在另一个视图中呈现它,那等价是什么？

我怎么能把它传给它？

编辑

实际上,我有一个父母的视图,我想在其中列出孩子(可编辑).这些我也可以单独编辑.简单的解决方案是,我创建一个_partial,我从父视图和edit.html.erb渲染.

我可以使用以下链接调用此edit.html.erb(或更新)：

<%= link_to( tag.content,method: :patch) %>

这有效.现在问题是如何使用渲染渲染部分(让我们称之为_update.html.erb)？仍然需要传递父(即对象)和子(标签)参数.如何使用<％render partial“标签/更新”PARAMS％>？

编辑完整示例

我想要实现的目标(简而言之) – 允许在注释视图(父)中编辑标签(子).

对于模型/对象“注释”的现有记录,我想为附加的PDF添加标签.我在名为“Annotate”的页面/视图中执行此操作,我从Annotation编辑视图打开(使用“link_to”).这个“Annotate”页面有2列(见下面的截图)：

>左侧窗格：2个部分 – 1个用于快速添加标签; – 2用于编辑现有标签(列在表格中)
>右窗格：PDF

标签和注释具有多态关系(根据此question设置)

路线

Rails.application.routes.draw do
  root 'dashboard#index'
  devise_for :users

  concern :tagable do
    resources :tags,only: [:new,:index,:create,:edit,:update]
  end

  resources :users,:documenttypes,:tagtypes,:business_partners
  resources :tags,only: [:show,:destroy,:index]

  resources :documents do
    resources :comments
    resources :tags,concerns: :tagable
    get "pdf",on: :member 
  end

  resources :annotations do
    resources :comments
    resources :tags
    get "pdf",on: :member

end

get "annotations/:id/annotate" => "annotations#annotate",as: 'annotate'

标签控制器

class TagsController < ApplicationController

    def index
    @tags = Tag.all.order(:tagable)
    end

  def show
    tagable = detect_tagable
    @tag = tagable.tags.find(params[:id])
  end

  def edit
    tagable = detect_tagable
    @tag = tagable.tags.find(params[:id])
    @tag.update(tag_params)
  end

  def create
    tagable = detect_tagable
    tagable.tags.create(tag_params)
    redirect_to tagable_path(tagable)
  end

  def update
    tagable = detect_tagable
    @tag = tagable.tags.find(params[:id])
    render 'edit'
#    @tag.save
    @tag.update(tag_params)
  end

  def destroy
    tagable = detect_tagable
    @tag = tagable.tags.find(params[:id])
    @tag.destroy
    redirect_to tagable_path(tagable)
  end

  private

    def tagable_path(tagable)
      case tagable
      when Document
        document_path(tagable)
      when Annotation
        annotate_path(tagable)
      else
        fail 'Unknown tagable'
      end
    end

    def detect_tagable
      if params[:annotation_id]
        Annotation.find(params[:annotation_id])
      elsif params[:document_id]
        Document.find(params[:document_id])
      else
        fail 'Tagable not found'
      end
    end

    def tag_params
      params.require(:tag).permit(:content,:location,:tagtype_id,annotation_attributes: { annotation_ids:[] },document_attributes: { document_ids:[] })
    end

end

这就是我所做的 – 如果有更好的方式在Rails(我可以成像)更愿意学习.
