RecordNotFound

[Franz Bettag]

Hi guys,

uhm how to fetch out a RecordNotFound?

i have this here

@new_ipv4 = Ipv4addr.find(IPAddr.new(params[:ipv4addr][:id]).to_i)

but at this line it gives an error RecordNotFound. But this is okay! But
now i want the application to do something special like adding the not
found IPaddr to the database.. But how? since it stops at this line =)

Thanks in advance!

Try using Ruby's exception handling:

begin
@new_ipv4 =3D Ipv4addr.find(IPAddr.new(params[:ipv4addr][:id]).to_i)
rescue
# Code to add data to database
end

Okay i got it myself. I did a .count before.. but that is quite unneeded
if you could check for RecordNotFound insted of just stopping there

Try using Ruby's exception handling:

begin
@new_ipv4 = Ipv4addr.find(IPAddr.new(params[:ipv4addr][:id]).to_i)
rescue

The above line would be better as:

rescue ActiveRecord::RecordNotFound

That way it doesn't hide errors we weren't expecting.

# Code to add data to database
end
