title: Rails - Submit multiple forms on same page
body: <p><strong>Model</strong>:
  Users have expenses.  Expense has a status.</p>
  
  <p><strong>View</strong>:
  As users add their expenses, they are shown in a list.  Each expense row has a form button on the end, which is used to submit the expense (changing the status of the expense).  This allows users to add expenses they have not completely filled out, and submit them when they are ready.  There is no parent form on this page, just the form buttons which submit the expense to a method which changes the status, and then reloads the page.</p>
  
  <p>Currently it works great, but users have asked to be able to "submit all" the expenses that are showing on the view with a single button.</p>
  
  <p><strong>Question</strong>:
  What is the proper way to handle this in rails?  Should I find a way to gather the array of expense id's and then submit a separate form?  Is there a way to ask for a set of records present in a view with a certain status?</p>
  
  <p>Thanks!</p>
