I compiled a list of the variations I have encountered in different
associations. I have not checked how behaviors are called.
When primary is set this is the structure I get just as in the
Cookbook:
array(
'0' => array(
'Model' => array(
'id' => 1
)
)
)
When primary is not set I get a subset of these for each association:
hasOne
array(
'id' => 1
)
habtm
array(
'0' => array(
'id' => 1
)
)
hasOne, hasMany, belongsTo
array(
'0' => array(
'Model' => array(
'id' => 1
)
)
)
habtm, hasMany
array(
'0' => array(
'Model' => array(
'0' => array(
'id' => 1
)
)
)
)
This makes the number of ifs and fors quite many in order the catch
them all. And since more than one is sometimes called for the same
record in the same request, you also have to check is you have already
manipulated your data. At least if you do something "destructive" to
it like encryption/decryption or serialization.
My orignal question still stands. What is the best way to write an
afterFind in order to: 1. not miss converting data in some queries 2.
not double-convert the data ?
