Feature request: generate dummy documents for a collection based on aldeed's SimpleSchema

[yanndebelgique]

You would use it like this :

Fake.docs(SimpleSchema);

Would spit out a document based on the SimpleSchema object. That would be freakin awesome! 👍

Great idea, thanks!

No problem! great work btw.
Can't wait to see what else you're going to build.

Haha, I just came here to make this very suggestion!
The ability to mock up objects with SimpleSchema would be absolutely incredible.

I had some additional ideas about it, concerning field names... If a field key contains:

• "name", generate something close to a name
• "description", generate a random sentence
• "birth", generate a Date not too far in the past (20-100 years?)
• And so on and so forth...

If the field is a string without min or max values, generate a string of length between Fake.docsValues.minStringLength and Fake.docsVaues.maxStringLength, those global values could be re-assigned by the user of course!
Similarly for an array, generate between Fake.docsValues.minArrayLength and Fake.docsValues.maxArrayLength values in that array.
If a field is optional have a Fake.docsValues.optionalChance chance to fill it...

In the Fake.docs function, take a second argument: An options object which would use the following fields:

• optionalChance : Number 0 = No optional values at all, 100 = All optional values are set
• All the values in my last paragraph, such as minStringLength and maxArrayLength

I can't wait to have such a feature!

The big problem here is dealing with regular expressions in an adequetly random fashion

I did some initial research today to find out whether this feature is viable. I couldn't find any information on retrieving a list of keys and their types from the doc of simpleschema.

But It is possible to find a list of keys from a simpleSchema object: they are stored in an array named _schemaKeys. Then there is another field named _schema holding type and other information for those keys. One can loop through the keys, then read the type e.g. String, Number etc. from the _schema. However, I feel a bit uncomfortable about using these private variables. These undocumented variables may change or disappear altogether in a future version. An implementation based on these variables may need regular maintenance depending on how frequently simpleschema changes their private variable names and the data structure.

If anyone else has looked into it, please share your thoughts and comments on this. Thanks.

I've added (limited) support for generating dummy documents according to a given SimpleSchema definition. Have a look at my pull request here: #20

Only Number, String and Boolean types are supported for the time being. Arrays will be added soon.
