Hello all,
with great difficulty , I guess I have finally been able to find the
appropriate git commit of paperclip which would suit my project's config
which is Ruby 1.8.7 and rails 2.0.2.
I am trying to implement a POC before I integrate paperclip in my
project. The POC is basically implementing each post with an appropriate
image beside it. It seems to pretty much work, its just that It
currently showing **routing errors** when it is trying to **fetch the
image**. I am able to see appropriate reflections in the DB showing that
the image has been inserted with the post message. I actually in my
Rails app can see the images being stored.. as per the default url used
by paperclip to store the images in the file system.
But I am unable to understand why is it unable to use the same url to
fetch back the image and display the same. I have basically implemented
this POC using rails scaffold and made some appropriate changes.
The routing error talks about using the get method, I am unable to
understand what role does get method play in fetching the image, I don't
have any such method in my controller..
Something seems to be fishy wrt this scenario.. please enlighten me on
the same on how exactly is the image supposed to be fetched and
displayed.. if I am doing it wrong some where.. kindly correct me on the
same..
I would like to add a photos directory is created in my app's root
directory and within that there is a directory which gets created every
time a new post is added with an appropriate image upload. This
directory name is coined with the an id, uniquely identifying each image
within it. The actual directory structure is like this:-
rail_app_directory/photo/id_number/orginal/photo_filename.appropriate_file_format
A more direct e.g. to the general structure posted above:-
post_with_image/photo/1/original/sunset.jpeg
Please find code for controller below just in case:-
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
Please find the code for my index.html.erb file:-
<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 %>
This is what I get doing a **tail -f log/development.log**

**[QUESTION EDITED]**
Please find the code for the model post.rb:-
class Post < ActiveRecord::Base
#require 'paperclip'
has_attached_file :photo
end
My routes.rb files looks like this:-
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
I am not sure where I am going wrong, Kindly help me with the same..
Thanks a lot for your help...
