Waterline Changelog

Edge

General
  • [BREAKING] Waterline attribute names must now be ECMAScript 5.1-compatible variable names.
    • Custom column names can still be configured to anything, as long as it is supported by the underlying database.
  • [BREAKING] Breaking changes to criteria usage:
    • For performance, criteria passed in to Waterline's model methods will now be mutated in-place in most situations (whereas in Sails/Waterline v0.12, this was not necessarily the case.)
    • Aggregation clauses (sum, average, min, max, and groupBy) are no longer supported in criteria. Instead, see new model methods.
    • limit: 0 no longer does the same thing as limit: undefined. Instead of matching ∞ results, it now matches 0 results.
    • skip: -20 no longer does the same thing as skip: undefined. Instead of skipping zero results, it now refuses to run with an error.
    • Limit must be < Number.MAX_SAFE_INTEGER (...with one exception: for compatibility/convenience, Infinity is tolerated and normalized to Number.MAX_SAFE_INTEGER automatically.)
    • Skip must be < Number.MAX_SAFE_INTEGER
    • Criteria dictionaries with a mixed where clause are no longer supported.
    • e.g. instead of { username: 'santaclaus', limit: 4, select: ['beardLength', 'lat', 'long']},
    • use { where: { username: 'santaclaus' }, limit: 4, select: ['beardLength', 'lat', 'long'] }.
    • Note that you can still do { username: 'santaclaus' } as shorthand for { where: { username: 'santaclaus' } } -- it's just that you can't mix other top-level criteria clauses (like limit) alongside constraints (e.g. username).
    • And as for anywhere you're building criteria using Waterline's chainable deferred object, then don't worry about this-- it's taken care of for you.
  • [DEPRECATE] Deprecated criteria usage:
    • Avoid specifying a limit of < 0. It is still ignored, and acts like limit: undefined, but it now logs a deprecation warning to the console.
  • [BREAKING] With the major exception of .populate(), repeated use of any other one chainable query method like .sort(), .where(), .set(), .meta(), etc is no longer supported. For example, you should not do: User.find().where({username: 'santaclaus'}).where({location: 'north pole'})
  • [BREAKING] Coercion of result records
    • Resulting records from calling model methods are no longer special instances-- they are just dictionaries (plain JavaScript objects)
    • There are now warning messages for some common problematic results from the adapter. This is designed to make it easier to catch schema migration issues, as well as to identify adapter bugs.
Automigrations
  • [BREAKING] Automigrations now live outside of Waterline core (in waterline-util)
    • Remove index for automigrations
    • In core SQL adapters, .create() and .createEach() no longer deals with updating the current autoincrement sequence (the "next value to use") when a record with a greater value is explicitly created
Data types
  • The data types in Waterline have changed to more closely reflect their purpose: validation and coercion of JavaScript values. This drastically reduced the number of types to just 5: string, number, boolean, json, and ref.
  • To allow for flexibility in automigrations, attributes may also specify a new key, columnType. If specified, the columnType is sent to the appropriate adapter during automigration (in sails-hook-orm). This allows Sails/Waterline models to indicate how the values for individual attributes should be stored at rest vs. how they are validated/coerced when your code calls .create() or .update().
  • All documented previously-supported types are checked for and adjusted if possible (in sails-hook-orm), but if you are using a custom type, you may need to choose an appropriate type and columnType.
  • defaultsTo can no longer be specified as a function. In practice, this can lead to unintended consequences, and its implementation was adding considerable weight and complexity to Waterline (without a whole lot of tangible benefit).
  • Optional attributes with no value specified are no longer necessarily stored as null. If they are set to type: 'json' or type: 'ref', and there is no defaultsTo, then null is stored. But, if an attribute declares itself as type: 'string', then when a record is created without specifying a value for that attribute, it is stored as '' (empty string). Similarly, type: 'number' is stored as 0, and type: 'boolean' as false. To represent an attribute which might be null or a string, use type: 'json' (combining it with the new isString validation rule, if you like).
Model methods
required & allowNull
  • [BREAKING] Standardizing the definition of required
    • If an attribute specifies itself as required, it means that a value for the attribute must be defined when using Waterline to do a .create().
    • For example, if foo is a required attribute, then passing in foo: undefined or omitting foo on a .create() would fail the required check.
    • In addition, trying to .create() OR .update() the value as either '' (empty string) or null would fail the required check.
  • If an attribute specifies itself as type: 'string', then if a value for that attr is explicitly provided as null in a .create() or .update(), it will no longer be allowed through-- regardless of the attribute's required status.
  • Other types (json and ref) allow null out of the box. To support a string attribute which might be null, you'll want to set the attribute to type: 'json'. If you want to prevent numbers, booleans, arrays, and dictionaries, then you'll also want to add the isString: true validation rule.

0.12.2

  • [BUGFIX] Fix issues with compatibility in alter auto-migrations. This was causing corrupted data depending on the permutation of adapter version and Waterline version. This should be fixed in the SQL adapters that support the new select query modifier.

  • [ENHANCEMENT] Updated dependencies to remove warning messages when installing.

0.12.1

  • [BUGFIX] Fixes an issue when searching by id in schemaless mode. See #1326 for more details.

0.12.0

  • [ENHANCEMENT] Allows attribute definitions to contain a meta property that will be passed down to the adapter. This allows arbitrary information about an attribute to be passed down to interactions on the physical storage engine. Going forward any adapter specific migration information should be sent via the meta property. See #1306 for more information.

  • [ENHANCEMENT] Allows for the use of .select() to build out projections in both top level queries and association queries. See #1310 for more details and examples.

  • [ENHANCEMENT] Allow for the ability to pass in extra data to an adapter function using the .meta() option. This could be used for a variety of things inside custom adapters such as passing connections around for transactions or passing config values for muti-tenant functionality. For more details see #1325.

0.11.6

  • [BUGFIX] Remove max engines SVR re #1406. Also normalize 'bugs' URL, and chang… … d89d2a6
  • [INTERNAL] Add latest Node versions, and add 0.11.x branch to CI whitelist. ca0814e
  • [INTERNAL] Add appveyor.yml for running tests on Windows. c88cfa7

0.11.5

0.11.4

0.11.2

  • [BUGFIX] Fixes an issue when searching by id in schemaless mode. See #1326 for more details.

0.11.1

  • [ENHANCEMENT] Handles fatal errors in validations better and returns clearer error messages for them. Who knew crashing the process would be bad? Thanks @mikermcneil

0.11.0

  • [BREAKING CHANGE] Removed the second argument from .save() commands that returns the newly updated data that has been re-populated. This should increase performance and limit memory. See #1295 for more details.

  • [ENHANCEMENT] Errors coming from .save() now return actual Error objects that have been extended from WLError.

  • [BUGFIX] Fixes issue with dynamic finders not understanding custom columnName attributes. See #1298 for more details. Thanks @HaKr for the detailed test case.

  • [ENHANCEMENT] Auto timestamps column names are now overridable. See#946 for more details. Thanks @Esya for the patch.

  • [ENHANCEMENT] Add support for an array of values to be passed into populate. ex .populate(['foo', 'bar']). See #1190 for more details. Thanks @luislobo for the patch.

  • [ENHANCEMENT] Ensures that createdAt and updatedAt are always the exact same on create. See #1201 for more details. Thanks @ziacik for the patch.

  • [BUGFIX] Fixed issue with booleans not being cast correctly for validations. See #1225 for more details. Thanks @edupsousa for the patch.

  • [BUGFIX] Fixed bug where dates as primary keys would fail serialization. See #1269 for more details. Thanks @elennaro for the patch.

  • [BUGFIX] Update support and patch some bugs in Many-To-Many through associations. See #1134 for more details. Thanks @atiertant for the patch.

0.10.30

  • [BUGFIX] Fix issue with maximum callstack when using dates as foreign keys. See #1265 for more details. Thanks @elennaro for the patch.

0.10.29

  • [ENHANCEMENT] Update version of Anchor to fix issue with email validations

  • [BUGFIX] Fix issue with through table joins. See #1134 for more details. Thanks @atiertant for the patch!

  • [ENHANCEMENT] Bump version of Waterline-Schema to the latest.

  • [ENHANCEMENT] Update Travis tests to run on Node 4 and 5.

0.10.27

  • [BUGFIX] Fix issue with invalid in criteria removing more data than it should. See #1076 for more details. Thanks @slester for the patch!

0.10.26

  • [BUGFIX] Fix issue with defaultsTo not setting values for undefined values.

0.10.25 and earlier?

See https://github.com/balderdashy/waterline/commits/f5efc0349fe9594a962357287bb6c25acdda9a76.

Earlier still?

For the first year or so, Waterline lived in the main Sails repo. See https://github.com/balderdashy/sails/commits/master?after=q8Jnoggc%2F%2B7O7021adjRanuRhssrNDM3NA%3D%3D and back.
