Waterline unique validation not detected until the next sailsjs server reset - express

Question

I am using sails#beta.
I am trying to create several Room models (see definition) below, the problem is that I can successfully create Room models with the same attribute 'name', although attribute 'name' has a unique validation.
The validation isn't detected until the next restart of 'sails' server, then I get this output:
C:\eMali_dev\server>sails lift
info: Starting app...
Express midleware for passport
Waterline encountered a fatal error when trying to perform the `alter` auto-migration strategy.
In a couple of seconds, the data (cached in memory) will be logged to stdout.
(a failsafe put in place to preserve development data)
In the mean time, here's the error:
Error (E_UNKNOWN) :: Encountered an unexpected error:
MongoError: E11000 duplicate key error index: eMali_beta_dev.room.$name_1 dup key: { : "e1" }

This was a bug in sails and it was fixed. Thanks everybody

Answer 2

You need to change the database from default Disk database to a database of your choice.
I was facing a similar problem and changing database from "Disk" to "MongoDB" fixed my issue.
It seems the default database is unable to enforce unique constraint.
I hope it solves your issue.
