title: Check if multi-insert transaction is successful or not
body: <p>I need to do some processing after a form is submitted that ends up saving multiple records in multiple tables. Since I need it to be all-or-nothing, I wrapped it in a transaction block. The block seems to work just fine, however I don't know how I can check whether or not the transaction was successful so I can return an appropriate response.</p>
  
  <pre><code>    ...
  
        # Start a transaction block so we can back out if anything fails
        ActiveRecord::Base.transaction do
  
          # Journal Entry for from_account
          gle = from_account.gl_journal_entries.create(....)
  
          # Journal Line (x2)
          gle.gl_journal_lines.create(....)
          gle.gl_journal_lines.create(....)
  
  
          # Journal Entry for to_account
          gle = to_account.gl_journal_entries.create(....)
  
          # Journal Line (x2)
          gle.gl_journal_lines.create(....)
          gle.gl_journal_lines.create(....)
  
        end
  
        # return something based on success/failure of transaction
  
      ...
  </code></pre>
