Re: HELP NEEDED with Auth "Component" in Views; Fatal error: While using Auth component inside a helper

[Sam Sherlock]

you'll find that ACL is a heavy task.

setting up a dummy application (own db files etc) -- deleting and reinstating things over  and over will make things clearer

trail and error extremely useful when learning ACL.  if you back up the db in between and compare what differences after doing things

bake creates models, controllers & views (you can scaffold but I don't -- or have'nt found it useful to me personally)
bake is not ACL - both ACL and bake have commandline access in cake

your on the right track by the souds of what your doing.

being prepared to redo various tutorials will really help you out;
The cookbook tutorial is good - but Marks end to end really hammered it home for me

see the buildAcl function in the tutorial

there are an awful lot of different terms involved with ACL and variations on setup to - 

auth is easy to set up ACL not so much (at all); also lots of tla's (three letter acronyms :) 
and this can be overwhelming)

stick with it - and keep pens and paper handy = coffee or whatever your choice beverage in plentiful supply

also if you use IRC you'll find lots of helpful people there

Thanks Sam, it's clearer now...but still struggling with Acl; I was
confused when I hear the word "populate" a general term. In oracle, I
populated db/tables/sql scripts in a batch file, last time. So it
brought me a meaning of the same when I hear it again. Now I know it
could mean using command line and here it's Bake. But I created the
tables already, is there a measurement to check if the tables are
correctly "populated" ? I may have to drop the 3 tables I created
earlier..and re-do starting from tutorial Acl(cookbook tutorial)
again/ the link you've sent to me. Will check on it, now.

Maxim
