Updating and Removing Data

Updating

Updating data is easily done through the update method.

david = database.findOne({name: 'david'})
david.name = 'dave'
database.changed(david) // true

database.update(david)

results = database.where({name: 'dave'})
results.length // 1
results = database.where({name: 'david'})
results.length // 0

Update takes an instance of Entry and overwrites the entry in the database with the new one.

Remove

Remove works much the same as Update taking an entry and removing it from the database.

dave = database.where({name: 'dave'})[0]
database.count() // 8
database.remove(dave)
database.count() // 7
