That's a tough question. I believe the best place to add such a feature would be in the validator functions of each attribute. You could check the type of the instance, and locally convert as necessary.
from jsv.
I see. How do I persist coerced instance? I see there are .getType(), .getValue(), but not _set_Value()?
from jsv.
Yea, JSV is not designed to handle changes on the fly. If you want to change an instance, you have to create a new instance with the new value.
from jsv.
By instance you mean the whole object being validated? Couldn't you throw a gist on how do I recreate the instance given a validation error occured?
from jsv.
Instances can be created using:
environment.createInstance(newValue, "uri");
from jsv.
I mean if I validate {a:{b:{c:"true"}}} and during validation the current execution point has dived two levels deep and is validating {c: "true"}, and I want to coercively validate "true" to be true
, how do I patch the instance being validated so that it contained {c: true}?
Possible?

Not without complications. I wouldn't recommend changing the instance being validated, but perhaps attaching a new instance to the report object that is a coerced copy of the instance being validated?
from jsv.
Great idea! I'd call it request for feature. Can I ask you to implement this?
from jsv.
Well, it's pretty low on my priority list; and I'm quite busy till January. If some other people express interest in this, I'll look into doing it then.

I'll point you to one very interesting case imho. When storing hierarchical data to redis, one chooses between storing the whole JSON, or each key separately. The latter case eases querying, sorting and so on, but the stored data are always stringy.
Being able to pipe fetched set of strings be coerced to real object by simple validation by your schema opens the way to store rich objects in redis!
from jsv.
Could you not store the value in a JSON format? What I mean is that in the redis value, you store the JSON primitive (null, boolean, number, string) as JSON:
null,
true, false,
0.0,
"string"
Then, when you extract the value from redis you use JSON.parse(), which will properly convert.
from jsv.
- JSON.parse() is way expensive
- what if i want to store string "true"
from jsv.
JSON.parse is way faster then using JSV. And if you wanted to store that string, you surround it in quotation (") marks, like you did there.
from jsv.
- JSV is supposed to be called once, JSON.parse() -- as much times as fields you have
- how do I know that I want it be string? I want procedure that saves/fetches records be neutral to what it saves/fetches. The only knowledge it should have -- the schema.
Nevermind, I respect your "no".
