The question is just above the last code snippet. Thank you.
(environment details are the end )
posts_controller.rb
class PostsController < ApplicationController
def create
@post = Post.new(params[:post])
respond_to do |format|
format.xml { render :xml => @post.to_xml(:include => [ :assets])}
end
end
posts.rb
class Post < ActiveRecord::Base
has_many :assets, :as => :attachable, :dependent => :destroy
end
asset.rb
class Asset < ActiveRecord::Base
belongs_to :attachable, :polymorphic => true
has_attached_file :data,
:url => "/assets/:id",
:path =>":rails_root/assets/:id_partition/:style/:basename.:extension"
def name
data_file_name
end
def content_type
data_content_type
end
def file_size
data_file_size
end
end
now when we post this information
POST /posts.xml HTTP/1.1
Accept-Encoding: gzip,deflate
Accept: application/xml
Content-Type: application/xml
User-Agent: Jakarta Commons-HttpClient/3.1
Host: localhost:8080
Content-Length: 60
<post><body>postbody</body><title>post_title</title></post>
a post entry gets created
and when I post this
POST /posts.xml HTTP/1.1

a new post gets created with 2 file attachments.
now the question is, I want to get the following HTTP post ( please notice the xml part before the file attachments) to also create a post with 2 attachments, with no additional changes ( to posts_controller or routes.rb). is that possible?
POST /posts.xml HTTP/1.1

on windows 2007 – 64 bit
At least rails 2.3.4 does not do this automatically. One needs to write a multipart/related parser and register it, inside initializers/mime_types.rb
NOTE : Feel free to update the hard coded values( like main and attachment part prefix etc.,) in your copy.
This same strategy can be used for multipart/related content as well. We are still debating whether to use multipart/related or multipart/mixed in this example below.

then, you can post your message like this. Nesting gets automatically taken with no further changes to the models or controllers.
