I'm trying to create a function that will take input in the form "a12345678"
and output text in the form "a12-34-5678" if and only if the input text is *
not* in the form "adam smith" The goal is to allow my users to enter either
names separated by a space, or the student id number into a single search
field and have the results be returned based on the format of the query.
I came up with the following code in my student model
def self.insert_dashes(term)
if /^([A-Z]|[a-z]|\d|-){11}$/.match(term)
term.insert 3, '-'
term.insert 6,'-'
end
end
def self.find_record(rec)
if /^([A-Z]|[a-z]|\d|-){11}$/.match(rec)
student=Student.where(:studentID=>rec).all
elsif /^([A-Z\s]|[a-z\s])+$/.match(rec)
split=rec.split ' ',2
f_name=split.first
l_name=split.second
student=Student.where(:fname=>f_name,:lname=>l_name).all
else
bar=insert_dashes(rec)
find_record(bar)
end
end
If I try to enter a string of the for "a12345678" I am greeted with the
following error:
SystemStackError (stack level too deep):
app/controllers/students_controller.rb:19:in `find_student'

Can anyone explain what the problem might be or a better approach to
accomplishing this particular task?
