Rails - Jun 2010 - rails+sinatra sent image

Hi!
I have simple rails application - users with name and avatar and in
sinatra I want to create new user.

form for new user

<form action="/users/create"
enctype="multipart/form-data"
method="post">
  <p>
    <label for="name">Name: </label>
    <input type="text" id="name"
name="user[name]" >
  </p>
  <p>
    <label for="avatar">Avatar: </label>
    <input type="file" id="avatar"
name="avatar" >
  </p>
    <input type="submit" name="Commit"
value="Create">
</form>

My action in sinatra

  post ''/users/create'' do
    RestClient.post("http://localhost:3000/users",
:user=>params[''user''])
    redirect ''/users''
  end

I would like to sent file to server in this action.

So the question is: How to sent file as a param to server ?
I''m using mozilla firefox 3.6 so I can''t get full file path to
read it

Looks like you can pass a :multipart option to RestClient to tell it
that the post should be multipart.

I tried next

post ''/users/create'' do
  RestClient.post("http://localhost:3000/users",
:user=>params[''user''],
:avatar=>File.read("/home/qwerty1/Desktop/client/views/images.jpeg"),
:multipart=>true)
  redirect ''/users''
end

---------------------------------------

require ''paperclip''
class User < ActiveRecord::Base
  has_attached_file :avatar, :styles=>{:thumb=>"100x100", 
:medium=>"200x200"}
 # validates_attachment_presence :avatar
end

but id didn''t sent any image to server

Am I doing something wrong ?

Did  you try setting a breakpoint in your rails app to see that the
image was being received properly. Does paperclip expect the name of
the uploaded file (which you aren''t currently transmitting) to have an
acceptable extension  or for the content type to be set ?

Solved :)

#POST create
  post ''/users/create'' do
    f = File.new("temp#{params[:user][:login]}.jpg", "w")
    t = params[:avatar][:tempfile]
    while c = t.gets do
      f.puts(c)
    end
    f.close
    RestClient.post("http://localhost:3000/users",:user=>{ 
:login=>params[:user][:login],
                                                          
:email=>params[:user][:email],
                                                          
:name=>params[:user][:name],
                                                          
:avatar=>File.new("temp#{params[:user][:login]}.jpg")},
                                                  :multipart=>true)
    File.delete("temp#{params[:user][:login]}.jpg")
    redirect ''/users''
  end
