I don't like doing two lookups for one record, but it works
What about
@user = User.find(:first, :conditions => {:id => 1})
if (@user)
blah, blah, blah
end
It's longer to type, but returns nil if the user doesn't exist.
Ugis almost has it. Try this
@user = User.find_by_id(1)
unless @user
flash[:notice] = "can't find user with given id"
redirect_to users_path
end
ActiveRecord::Base#find_by_id is a dynamic finder that will work just
like the line Simon has above--nil if there is no record found.
