sendfile - Rails, Download from BLOB database -

I have a problem, I save my upload data in the database file in the Blob file.

Now I want to download it ..

How to manage

I have tried this way (document_file is an area with blob data)

send_file @attachment .document_file ,: Nature =>

Thanks

Maybe you send_data for blob data instead of send_file Should use:

  send_data @ attachment.document_file ,: disposition = & gt; 'Attachment'    Consider that the 'Attachment' is the default value, so you can leave it because you should get this error because send_file needs the file path as the argument, no That no blob

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
