Hi,

I've seen a lot of examples in Rails code where they're accessing what appe=
ar
to be instance variables from self. Something like

self.foo =3D true

Now, I'm assuming that you can only access methods this way, so this is
actually a method call of

self.foo=3D(true)

Is that right? I'm not always clear on it.

Thanks,
Mike

That is correct.

And you're also apparently a bit confused about what's really happening.

self.foo = true
becomes:
self.foo=(true)
which typically implies something like:

def foo=(foo)
@foo = foo
end

But you probably are more used to seeing something like:

attr_accessor :foo

which sets up the "def foo;@foo;end" and "def foo=(foo);@foo=foo;end"
for you.
