Question

我有两个关联模型，船has_many :pictures，图片模型belongs_to :boat，这些是嵌套路线；

resources :boats, except: :destroy do
      resources :pictures
end

所以，我有索引页，所有的船都在那里显示。但我也想在那里添加上传照片表单，之后我会添加一个 JQuery 选项。把我的表格有问题。因为我在 index 页面中，所以我必须从索引页面将表单发送到 #create 操作；

这里是图片控制器；

class PicturesController < ApplicationController
  before_action :logged_in_user
  before_filter :load_parent

  def index
    @pictures = @boat.pictures.all 
  end

  def new
    @picture = @boat.pictures.new
  end

  def show
    @picture = @boat.pictures.find(params[:id])
  end


  def create

    @picture = @boat.pictures.new(picture_params)
    if @picture.save
      #flash[:success] = "Continue from here"

      redirect_to boat_pictures_path(@boat)
      #redirect_to boat_path(@boat)
    else
      render 'new' 
    end
  end

  def edit
    @picture = Picture.find(params[:id])
  end

  def update
    @picture = @boat.pictures.find(params[:id])

    if @picture.update_attributes(picture_params)
      flash[:notice] = "Successfully updated picture."
      render 'index'
    else
      render 'edit'
    end
  end

  def destroy

    @picture = @boat.pictures.find(params[:id])
    @picture.destroy

    flash[:notice] = "Successfully destroyed picture."
    redirect_to boat_pictures_path(@boat)
    #redirect_to boat_path(@boat)
  end


  private

    def picture_params
      params.require(:picture).permit(:name, :image)
    end

    def load_parent
     @boat = Boat.find(params[:boat_id])
    end

end

这里是索引视图；

<% @pictures.each do |pic| %>
</br>
<%= pic.name %>
<%= image_tag pic.image_url(:thumb).to_s  %>
<%= link_to "edit", edit_boat_picture_path(@boat, pic) %> |
<%= link_to 'Destroy', boat_picture_path(@boat, pic), confirm: 'Are you sure?', method: :delete %> | 
</br>
<% end %>
<%= link_to "add", new_boat_picture_path(@boat, @picture) %>

<%= form_for Picture.new, :as => :post, :url => new_boat_picture_path(@boat, @picture) do |f| %>
 <%= f.file_field :image, multiple: true, name: "picture[image]" %>   

<% end %>

我认为 <%= form_for Picture.new, :as => :post, :url => new_boat_picture_path(@boat, @picture) do |f| %> 是 url 不正确的问题。没有提交按钮来发送它，但这是因为我将使用 JQuery 文件上传。

Answer 1

是的，这部分肯定是错的。

在您的控制台中输入：rake routes 并在列表中查找正确的路径。

我想会是boat_pictures_path(@boat)
