SoftAttributes¶ ↑
Calculated fields are usually not stored in the database. But, in many cases, you would want to treat them just like attributes - serializing them into the xml/json representation, discarding them if they appear on the incoming xml/json payloads, lazily initializing them (in case you are loading them from an expensive ActiveResource call), etc. You will also want to access them by either methods or [] notation.
GOALS¶ ↑
The major distinguishing features of SoftAttributes are:
-
To not pollute the attributes hash by putting non-persisted variables in them.
-
But at the same time, to maintain a list of attributes that can get accessed.
-
These attributes could be lazily loaded (and cached in the instance, once they are retrieved - to avoid multiple ActiveResource calls)
-
To provide an easy way to inject them into the xml/json payload as needed.
EXAMPLE¶ ↑
class Foo
#will define a setter method that ignores the param noop_setter :bar
