Scenario: I have a collection:
{ "name" : "A", "value" : 1, "date" : ISODate("2014-01-01T00:00:00.000Z") }
{ "name" : "B", "value" : 7, "date" : ISODate("2014-01-01T00:00:00.000Z") }
{ "name" : "A", "value" : 3, "date" : ISODate("2014-01-02T00:00:00.000Z") }
{ "name" : "B", "value" : 8, "date" : ISODate("2014-01-02T00:00:00.000Z") }
{ "name" : "B", "value" : 8, "date" : ISODate("2014-01-03T00:00:00.000Z") }
{ "name" : "A", "value" : 5, "date" : ISODate("2014-01-04T00:00:00.000Z") }
{ "name" : "A", "value" : 4, "date" : ISODate("2014-01-05T00:00:00.000Z") }
The document for A on 3rd Jan 2014 is not available. When I do a find/aggregate on A with a date range from 1/Jul/14 to 31/Jul/14, I would like the document to appear in my result set with a default value (or value same as previous date). For example:
{ "name" : "A", "value" : 1, "date" : ISODate("2014-01-01T00:00:00.000Z") }
{ "name" : "A", "value" : 3, "date" : ISODate("2014-01-02T00:00:00.000Z") }
{ "name" : "A", "value" : 3 (or default value -1), "date" : ISODate("2014-01-03T00:00:00.000Z") }
{ "name" : "A", "value" : 5, "date" : ISODate("2014-01-04T00:00:00.000Z") }
{ "name" : "A", "value" : 4, "date" : ISODate("2014-01-05T00:00:00.000Z") }
