We occasionally have a user pressing "submit" button more than once.
I know I can disable submit button using "onclick".
But I sometimes need a more solid solution especially
for a form that could change a record inside the database.
What could be the best way to solve the problem?
I need to access to the existing database record first and
compare the record with a new coming record.
I am now thinking about checking almost all attributes.
Assuming this is a simple blog, I would check the title
and post for exact match.
I was trying to find an open source Rails app to have
a solution, do you know any?
Any help would be appreciated.
