Until I made a simple change to the orginal .fla, and overwrote the vidGirl_home...

I'm writing my own file upload in rails. I saw some related questions but it doesn't answer my question. I use File.open ("#{RAILS_ROOT}/public/docs/attachments/#{@file_name}", "wb") {|f| f.write(@temp_file.read)} to write the file on my local machine (OS: Windows XP) instead of saving it in database. I got a Permission denied error o...

My Lucene/Solr database contains a date column (created_at) that I need to use as a condition in a query. I'm new to RoR and assume that RoR automatically uses its own date object upon anyObject.save, and that Solr in turn reindexes that column in its own way. Regardless, the date is in this format: "2008-06-03 11:15:20" I can write ...

I have a Rails app that needs to send SMS messages to users but does not need to receive messages. Is there a free way to do this programmatically? If so, how free is it - do they charge if you go over a certain number of messages? I know Gmail allows you to send SMS messages now. But I'm not sure if this means you could also send an S...
