[英]Carrierwave - upload photo from index page
我有兩個關聯的模型,Boats has_many :pictures
,Picture Model belongs_to :boat
,它們是嵌套的路線;
resources :boats, except: :destroy do
resources :pictures
end
所以,我有索引頁面,所有的船都顯示在那里。 但我想在這里添加JQuery選項后,也要在其中添加上傳照片表格。 我的表格有問題。 正如我在index
頁中一樣,我必須將表單發送到索引頁中的#create action;
這是圖片控制器;
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
這是索引視圖;
<% @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 %>
我認為<%= form_for Picture.new, :as => :post, :url => new_boat_picture_path(@boat, @picture) do |f| %>
<%= form_for Picture.new, :as => :post, :url => new_boat_picture_path(@boat, @picture) do |f| %>
是網址不正確的問題。 沒有要發送的提交按鈕,但這是因為我將使用JQuery文件上傳。
是的,該零件肯定是錯誤的。
在控制台中,輸入: rake routes
然后在列表中尋找正確的路徑。
我認為這將是boat_pictures_path(@boat)
