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

Hi John,

you want to setup cake so you can use it from commandline

bake is one part of cakes commandline

also acl too: (output from commandline)

$ cake acl
Available ACL commands:
         - create
         - delete
         - setParent
         - getPath
         - check
         - grant
         - deny
         - inherit
         - view
         - initdb
         - help

so `cake acl initdb` would setup the db structure which you previously posted

you don't have to, setup cake to run from commandline, but it is an advantage if you do

also checkout the ACL tutorial by Mark Story (end to end acl parts 1 & 2); it covers
populating the tables and setting up controllers models etc - its the least confusing acl tutorial out there :)

additionally acl_extras a shell plugin is truly useful (also by Mark Story)

Is Bake continued from scaffolding ? can I jump straight to learn
Bake ?

Must we use Bake to populate the Acl tables ?
