ruby on rails - Remove flash message on refresh of page -

-

I am planning to log in and I have overwritten my design session controller and the user has the following information Showing the flash message when entering incorrect information using Code to display flash message. 

  & lt;% flash.each do | Name, msg & Gt%; & Lt;% = content_tag: section, msg,: id = & gt; "Flash _ # {Name}" ,: Category = & gt; "Flash"%> & Lt;% end% & gt;   
 And if the user enters wrong email and password, then it is working fine and showing  "invalid email or password"  message.  
 Now even if I refresh the page, that flash message is still visible but I need to delete the flash message if the page is refreshed. Please help me   
 
 
 You can use flash.discard after the display. Probably like:  
  & lt;% flash.each do | Name, msg & Gt%; & Lt;% = content_tag: section, msg,: id = & gt; "Flash _ # {Name}" ,: Category = & gt; "Flash"% & gt; & Lt;% free.discard (name)% & gt; & Lt;% end% & gt;   
 I have not tested it, so try that it works.
