Motivation
Sometimes it's useful to retrieve some default value from a Model, even if that value doesn't exist in the db (or not even an actual model attribute, if waiting implementation).
This fallback value isn't persisted, but rather acts as a sane default when the actual value returns true on
_.isEmpty( value )
. I found it useful in view templates, when I don't want to inline a lot of ternary logic like:It is basically equivalent to Python's
dict.get(key, default=<something>)
or Ruby'sHash#fetch(key, [default])
. I do realizeModel#get
is a core method, so I'm not taking this addition lightly.I've searched existing issues, but couldn't find something similar. Apologies in advance if I missed one. I did my best to stick to the guidelines, so hopefully things are in order.
Thanks!
