If I tell you that the 'inject' bit is replacing something like:
Content.with_scope(scope_hash) do
Article.with_scope(scope_hash) do
Comment.with_scope(scope_hash) do
Trackback.with_scope(scope_hash) do
super
end
end
end
end
does it help?
Other helpers:
lambda is roughly equivalent to Proc.new
This:
foo = lambda { "Bibble" }
some_method(&foo)
is roughly equivalent to:
some_method() {"Bibble"}
The rest is just a matter of reading the docs :)
