sails v0.10.0-rc7 unique constraint not working

问题

I upgraded my sails from rc4 to rc7 today, and the unique constraint on my model stopped working. note that in rc4 it used to work perfectly. and sails-mongo version on both versions i tried is: "sails-mongo": "^0.10.0-rc5"

Model attribute:

    emailAddress: {
        type: 'email',
        required: true,
        unique: true
    },

any issues?

回答1:

As already stated it's a bug in waterline/sails-mongo

I however advise against setting syncable to true as it was set to false by the developers for a reason (the github bug report explains more, also already stated igor)

If you require uniqueness you can just create an index in the DB manually. Not a great solution if you're deploying to different environments, but as a temporary work around it'll do.

http://docs.mongodb.org/manual/tutorial/create-a-unique-index/

After all, we're using an RC for a piece of software at version 0.10, this kind of thing should be expected.

Although it's month old, just came here from Google, so for the reference, it is apparently known issue (check here for details: https://github.com/balderdashy/sails-mongo/issues/152)

As It's mentioned there, you can quick-fix this by setting

syncable = true

though that might imply some other problems (auto-migrating on no-sql databases)
