Mongo Error When Calling destroyAll

[Christopher Moffatt]

I am getting an "unknown operator: $principalId" when executing the code below.  I cannot figure out why.

var RoleMapping = app.models.RoleMapping;
RoleMapping.destroyAll( { where: { principalId: userId } }, function(err, obj)
{
  ...
} );

;

Please remove the 'where' layer. destroyAll takes the where value directly.

Thanks, that worked!

You should update the docs at http://apidocs.strongloop.com/loopback/#persistedmodel-destroyall to reflect that 

destroyAll takes the where value directly

The API docs actually reflect the correct syntax, although I agree they could be clearer.  The signature given is PersistedModel.destroyAll([where], callback) with [where] given as {key: val, key2: {gt: 'val2'}, ...}. 

I added a new section to there Where filter article to highlight that the where clause has slightly different form for queries and update/delete operations; and some cress-reference notes in Creating, updating, and deleting data.  I'll try to clarify the API docs as well.

Thanks,

Rand

FYI, Rand. The issue was raised before I fixed the jsdoc - https://github.com/strongloop/loopback/commit/0f9dd93abacf451f09fff9a6d99ec4d13d1c2a29.

Thanks,

My bad.  I was out last week, and didn't realize that Raymond had made that fix.

Thanks for bringing it to our attention.

Thanks,
