Compose the _id for a document in a partition database

[jannyHou]

See parent story #214

For a non-partitioned db, db.insert() will give the document a random string as _id if it’s missing in the payload. While for partitioned database, _id is a must provide field, the random string need to be generated using 'uuid/v4', see some examples in the driver repo. Let's figure out a better UX for users to provide the id part.

Considering when inserting document into a partitioned db, people MUST provide value for _id with partitionKey specified, let's either

• honour the full value of _id from model's id field (invalid value will be rejected by Cloudant service)
  or
• if the model contains a property marked as partitionKey:
  • if id is in pattern <partitionKey>: id, use the full value
  • otherwise compose the id field and partitionKey field as <partitionKey>: id

Acceptance Criteria

• Improve the create() method to handle the _id composition in a partitioned database

  • honour the full value of _id from model's id field (invalid value will be rejected by Cloudant service)
    or
  • if the model contains a property marked as partitionKey:
    • if id is in pattern <partitionKey>: id, use the full value
    • otherwise compose the id field and partitionKey field as <partitionKey>: id

• Developers can config the partition key property follows:

  customers = db.define('customers', {
  userId: {type: Number, id: true},
  countryCode: {type: String, isPartitionKey: true},
  name: String,
  zipCode: Number,

});
