I have two simple classes. One inherits from the other and calls "super()" in its initialize method. But the super does not seem to do what I expect it to do. I expect the super() to initialize two variables, but when I call the method to display the initialized errors, I do not get the value (it things @errmsg is nil). Here they are:
class DBBase
def initalize @failed = false @errmsg = 'n/a'
end
def clear @failed = false @errmsg = 'n/a'
end
def failure @failed
end
def success @failed != true
end
def error
"Error: #{@errmsg}"
end
def connect
SQLite::Database.new(DBNAME)
end
attr_accessor :failed, :errmsg
end
(and here is the shortened version of the inheriting class)...
## This class models the People table. It allows the creation,
## loading, modification and saving of a single person.
class Person < DBBase
def initialize(id=nil, lname=nil, fname=nil, mname=nil, nname=nil, sex=nil, dob=nil)
super() @id = id @lname = lname @fname = fname @mname = mname @nname = nname @sex = sex @dob = dob
if @id != nil @added = false
else @added = true
end
I have two simple classes. One inherits from the other and calls "super()" in its initialize method. But the super does not seem to do what I expect it to do. I expect the super() to initialize two variables, but when I call the method to display the initialized errors, I do not get the value (it things @errmsg is nil). Here they are:

end
The initialize method in class DBBase is spelled incorrectly.

You missed 'initialise'! (I remember various ruby-lint projects being
mentioned in the past - anyone know what happened to them?)

I almost added that, but I coudn't think of a humorous way to accuse
the programmer of being a Queen's English speaker (maybe that's humorous
enough as it is).

If any one really wants to use this, then to make sure there are no
false positives, we should permit #initial. According to one local
dictionary on my system, initial and initialize are the only matches for
the regex.
module CodeNanny
def method_added(m)
if /^in[ital]{2,6}[alize]{2,6}\b/ =~ m.to_s
if m != :initialize and m != :initial
warn "Did you type too fast again? '#{m}' != 'initialize'"
end
end
