POuploading a file to Rails JSON API server with Paperclip and Multipart request
text
Body
copied!<p>I want to upload a file from an Android client to a Rails JSON API server.</p> <p>I'm sending a Multipart/form request from the Android client which looks like that:</p> <pre><code>Content-Type: multipart/form-data; boundary=d99ArGa2SaAsrXaGL_AdkNlmGn2wuflo5 Host: 10.0.2.2:3000 Connection: Keep-Alive User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.4) --d99ArGa2SaAsrXaGL_AdkNlmGn2wuflo5 Content-Disposition: form-data; name="POSTDATA" Content-Type: application/json; charset=UTF-8 Content-Transfer-Encoding: 8bit {"tags":["test"],"location_id":1,"post":{"content":"test"}} --d99ArGa2SaAsrXaGL_AdkNlmGn2wuflo5 Content-Disposition: form-data; name="IMAGEDATA"; filename="testimage.jpg" Content-Type: image/jpeg Content-Transfer-Encoding: binary <BINARY DATA? --d99ArGa2SaAsrXaGL_AdkNlmGn2wuflo5-- </code></pre> <p>in the rails controller i'm creating the new post with this code:</p> <pre><code>@parsed_json = JSON(params[:POSTDATA]) @post = @current_user.posts.new(@parsed_json["post"]) </code></pre> <p>how do I make Paperclip save the attachment from the multipart form ?</p> <p>I can do it with something like this:</p> <pre><code>if params.has_key?(:IMAGEDATA) photo = params[:IMAGEDATA] photo.rewind @filename = "/tmp/tempfile" File.open(@filename, "wb") do |file| file.write(photo.read) end @post.photo = File.open(@filename) end </code></pre> <p>but it doesn't look like the best solution, also, the filename that is being passed in ther multipart request is not used.</p>
