Rails is funny, I had been using PHP since 2001, and I learned many
other programmer language, but rails is hard to find around, the manual
is messy, you cannot get any good description from it as shown below!
Overwrite this method for validation checks on all saves and use
Errors.add(field, msg) for invalid attributes.
This above doesn’t help me anyway to know how to use this method :S:S:S:
and then I tried to find anything on google search results, and ended
if params[:user][:username].blank? @errors << " missing"
*This again does aren’t working :(…
Can anyone help me out there to know how to get started, things are more
complicated then I thought, I don’t think you would like me to create
new topic every time I face a problem and use 1 hour on it.
