Rails+sinatra sent image

Rails
1

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

form for new user

Name:

Avatar:

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 :slight_smile:

#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
