Upgrading to 2.2.0: setting DateTime fields

[Adam Warski]

Hello,

another common compilation that I have when upgrading from rogue 1.1.8 to 2.2.0 is:

    could not find implicit value for evidence parameter of type com.foursquare.rogue.BSONType[java.util.Calendar]

when trying to modify a net.liftweb.record.field.DateTimeField (or OptionalDateTimeField):

    someMeta.where(_.id eqs id).modify(_.deletedAt setTo now)

where now has type java.util.Calendar (as required by the DateTimeField).

Is it possible to set a DateTimeField using Rogue in 2.2.0?

Rogue does not support Calendar. You need to use the DateField that's in the net.liftweb.mongodb.record.field package.

Also, note that you can use either Date or Joda's DateTime in your query.

I see, migrating to DateField then :) Using Joda in the queries will be great for sure :)

Thanks,

Adam

I have this same error when trying to add orderDesc on a DateTimeField

class UserEvent extends MongoRecord[UserEvent] with ObjectIdKey[UserEvent] with IndexedRecord[UserEvent] {

  def meta: MongoMetaRecord[UserEvent] = UserEvent

  object pid extends ObjectIdField(this)

  object createdOn extends DateTimeField(this)

  object changedOn extends DateTimeField(this)

And then later when trying to sort on that field:

val userEvents = UserEvent.where(_.pid eqs new ObjectId(id)).and(_.kind eqs "users.login").orderDesc(_.createdOn).fetch(limit.getOrElse(10))

Generates: 

could not find implicit value for evidence parameter of type com.foursquare.rogue.BSONType[java.util.Calendar]

Any suggestions?

I also tried, the newer JodaTimeField

could not find implicit value for evidence parameter of type com.foursquare.rogue.BSONType[org.joda.time.DateTime]

[error]                   val userEvents = UserEvent.where(_.pid eqs new ObjectId(id)).and(_.kind eqs "users.login").orderDesc(_.createdOn).fetch(limit.getOrElse(10))

Changed to DateField, compilation errors resolved and sorting works....

class UserEvent extends MongoRecord[UserEvent] with ObjectIdKey[UserEvent] with IndexedRecord[UserEvent] {

  def meta: MongoMetaRecord[UserEvent] = UserEvent

  object pid extends ObjectIdField(this)

  object createdOn extends DateField(this)

  object changedOn extends DateField(this)
