Can you handle the default values at the model layer instead? A "Custom schema" might get you what you want.
Semantically, the city is nil
(or null
in SQL lingo): it wasn't provided. That you want to present it as "n/a" shouldn't affect how you store it.
Honestly, I'd probably go higher than the model and handle this in a Presenter
.
I know this might not be the answer you want, and there might be some underlying issue here that we need to fix, it just seems like there's a better way to accomplish what you're trying to do. (Maybe this DB interacts with another app and that's why you have to do it this way, I don't know.)
from model.
I guess a work-around would be to convert the entity into a hash and compact it. Then all keys where the value is nil would be removed (empty strings would still be around though!) and defaults of the database should be filled in.
A better approach would be to have defaults specified in the entity. In that case one needs to create a custom schema... @cllns Couldn't the auto-discovery of the schema also consider defaults?
from model.
If the column allows NULL
s and you send a nil, this one will get persisted as this was what you asked for (or so the underlying layers think).
Same goes with the empty string. @whysthatso You can probably properly handle these with a validator either on the Action or Interactor level.
