无法通过文件系统使用回形针插件通过get方法
很难找到图像路径,我想我终于能够找到适合我的项目配置的Ruby 1.8的适当的git提交。 7和导轨2.0.2。无法通过文件系统使用回形针插件通过get方法
我试图在将回形针集成到我的项目中之前实施POC。 POC基本上在每个帖子旁边都贴上了一个适当的图片。它似乎很多工作,它只是它目前显示路由错误当它试图获取图像。我能够在数据库中看到适当的反射,显示图像已经插入了发布信息。实际上,在我的Rails应用程序中,可以看到正在存储的图像。按照回形针用于将图像存储在文件系统中的默认网址。
但我无法理解为什么它无法使用相同的URL来取回图像并显示相同。我已经基本实施了这个POC使用轨道脚手架,并做了一些适当的修改。
路由错误谈到使用get方法,我无法理解在获取图像时获取方法的角色是什么,在我的控制器中我没有任何这样的方法.. 东西似乎是鱼腥味这个场景..请赐教我关于如何是应该被提取和显示的图像..如果我做错了一些地方..请在相同的地方纠正我..
我想添加...照片目录是在我的应用程序的根目录中创建的,其中有一个目录,每次添加新帖子并添加适当的图片时都会创建一个目录。该目录名称是用一个ID创建的,唯一标识其中的每个图像。实际的目录结构是这样的: -
rail_app_directory/photo/id_number/orginal/photo_filename.appropriate_file_format
更直接的例如上面贴的一般结构: - post_with_image/photo/1/original/sunset.jpeg
请在下面找到以防万一的控制器代码: -
class PostsController < ApplicationController
# GET /posts
# GET /posts.xml
def index
@posts = Post.find(:all)
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @posts }
end
end
# GET /posts/1
# GET /posts/1.xml
def show
@post = Post.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @post }
end
end
# GET /posts/new
# GET /posts/new.xml
def new
@post = Post.new
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @post }
end
end
# GET /posts/1/edit
def edit
@post = Post.find(params[:id])
end
# POST /posts
# POST /posts.xml
def create
@post = Post.new(params[:post])
respond_to do |format|
if @post.save
flash[:notice] = 'Post was successfully created.'
format.html { redirect_to(@post) }
format.xml { render :xml => @post, :status => :created, :location => @post }
else
format.html { render :action => "new" }
format.xml { render :xml => @post.errors, :status => :unprocessable_entity }
end
end
end
# PUT /posts/1
# PUT /posts/1.xml
def update
@post = Post.find(params[:id])
respond_to do |format|
if @post.update_attributes(params[:post])
flash[:notice] = 'Post was successfully updated.'
format.html { redirect_to(@post) }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => @post.errors, :status => :unprocessable_entity }
end
end
end
# DELETE /posts/1
# DELETE /posts/1.xml
def destroy
@post = Post.find(params[:id])
@post.destroy
respond_to do |format|
format.html { redirect_to(posts_url) }
format.xml { head :ok }
end
end
end
请找到代码为我的index.html.erb文件: -
<h1>Listing posts</h1>
<table>
<tr>
<th>Message</th>
</tr><br/>
</table>
<% for post in @posts %>
<%= image_tag post.photo.url %>
<table>
<tr><td><%=h post.message %></td></tr>
<tr><td><%= link_to 'Show', post %></td>
<td><%= link_to 'Edit', edit_post_path(post) %></td>
<td><%= link_to 'Destroy', post, :confirm => 'Are you sure?', :method => :delete %></td></tr>
</table>
<br/> <hr/>
<% end %>
<br />
<%= link_to 'New post', new_post_path %>

[问题EDITED]
请找到该模型post.rb代码: -
class Post < ActiveRecord::Base
#require 'paperclip'
has_attached_file :photo
end
我的routes.rb文件看起来是这样的: -
ActionController::Routing::Routes.draw do |map|
map.resources :posts
# The priority is based upon order of creation: first created -> highest priority.
# Sample of regular route:
# map.connect 'products/:id', :controller => 'catalog', :action => 'view'
# Keep in mind you can assign values other than :controller and :action
# Sample of named route:
# map.purchase 'products/:id/purchase', :controller => 'catalog', :action => 'purchase'
# This route can be invoked with purchase_url(:id => product.id)
# Sample resource route (maps HTTP verbs to controller actions automatically):
# map.resources :products
# Sample resource route with options:
# map.resources :products, :member => { :short => :get, :toggle => :post }, :collection => { :sold => :get }
# Sample resource route with sub-resources:
# map.resources :products, :has_many => [ :comments, :sales ], :has_one => :seller
# Sample resource route within a namespace:
# map.namespace :admin do |admin|
# # Directs /admin/products/* to Admin::ProductsController (app/controllers/admin/products_controller.rb)
# admin.resources :products
# end
# You can have the root of your site routed with map.root -- just remember to delete public/index.html.
# map.root :controller => "welcome"
map.root :controller => "posts"
# See how all your routes lay out with "rake routes"
# Install the default routes as the lowest priority.
map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'
end
我我不知道我要去哪里错,请帮助我一样..
非常感谢您的帮助...
只是为了对这个问题的意见正式的答案:
你需要确保你的/photo/4/original/ruby-on-rails.jpg
public
文件夹下存在的,因为这就是回形针应该是默认存储所有的附件。
我想补充..这适用..提供您使用它的一个lates t commit ... :),我用2008年3月18日的一个提交来满足我的配置需求..从Github ..它已经将它存储在我的rails根目录中..只有在我复制到公共目录后才能工作对于我来说......总是有人无法继续为每一张新图片添加..(这是我使用提交时的经验..,我只是提到这是为了任何人的利益,谁会需要它..不是反驳你的答案或以任何方式冒犯你......) – boddhisattva 2011-05-21 08:30:33
你可以发布你的路线文件和显示回形针代码的模型代码吗? – 2011-05-19 14:35:58
你也可以用' '而不是for in语法 – 2011-05-19 15:17:59
@dmarkow:我已经为模型和路径文件添加了代码以用于问题..我只想提到,我最初我不确定我的应用程序是否会检测到宝石。因此,我最初给出了一个require'paperclip',但是当我确认应用程序能够成功地从供应商目录中检测插件时,我评论了相同的内容我的导轨应用程序.. – boddhisattva 2011-05-19 15:20:07
