• Extra Iterations in Data Array (hasMany Mistake)

  Code

  Just a quick one today, if you find you are having to use nested Set::Extracts or nested foreach loops in your code to extract data then it is possible you have some incorrect associations.
  For instance if you array looks like this:
  Array ( [0] => Array [...]

• REST with CakePHP

  Code

  I recently had a bit of a brain block how to do a certain thing in cakePHP – I basically wanted to update a model from a view but not using a GET method (as that would have allowed URL manipulation – and potentially created problems).
  The simple answer (again thanks to Darren at zeen.co.uk) is [...]

• Pagination Across Models / Associations

  Code

  For a CakePHP n00b the pagination thing might seem a bit complicated. Well to be frank it is in someways. For instance you can only currently paginate stuff easily when there is a model involved!

  $this->UserProfile->User->Friend->recursive = -1;
  $this->set(’userFriends’, $this->paginate($this->UserProfile->User->Friend,

  Code

  Right,
  When I started out on this I hit t’internet looking for any kind of hints as to the best way of going about this. The first thing I came across was the use of a Self Referential HABTM relationship ( User<-HABTM->User ), naturally not being the uber Cake Nerd this really didnt work out too [...]
