- validateUpsert:true reports validation errors back to the callback
- validateUpsert:false does not call `isValid()` at all
- any other value report validation errors via `console.warn`
When a required number property is set to NaN, for example as a result
of coersion (`Number([1,2,3])`), the "presence" validation now correctly
reports an error.
Fix the implementation of updateOrCreate (a.k.a. upsert) to validate
the model before calling the connector.
In order to preserve backwards compatibility, validation errors are
only logged via console.warn by default.
The correct behaviour, where validation errors fail the updateOrCreate
operation, can be enabled via new model setting "validateUpsert".
When a callback is omitted from a method on a model relation that
supports promises, return that promise. This includes all the standard
DAO methods, as well as any user-defined methods that return promises.
e.g.:
mylist.todos.create({name: 'Item 1'}) // returns Promise
This API will use native ES6 promises if available. If not available,
or to force the use of another Promise library, you must assign the
global.Promise object.
e.g.:
global.Promise = require('bluebird')
Relations affected:
- BelongsTo
- HasOne
- HasMany
- HasManyThrough
- HasAndBelongsToMany
- ReferencesMany
- EmbedsOne
Exceptions:
The EmbedsMany relation has not been promisified, because most of the
methods return synchronous values.
The base relation getter method [e.g.: mylist.todos()] has not been
promisified, due to its default caching behavior.
New Methods:
- getAsync(condition, cb)
A new method "getAsync()" has been added to all relations except
EmbedsMany, which always fetches from the datasource rather than from
the cache. It takes an optional "where" condition (except for HasOne
and BelongsTo) and an optional callback. If the callback is omitted,
a Promise is returned.
When the setting "persistUndefinedAsNull" is true,
the model will use `null` instead of `undefined` in
all property values.
- Known optional model properties are set to `null` when no value
was provided.
- When setting model properties, `undefined` is always converted
to `null`. This applies to both known (model-defined) properties
and additional (custom, dynamic) properties.
- The instance method `toObject()` converts `undefined` to `null` too.
Because `toJSON()` calls `toObject()` under the hood, the change
applies to `toJSON()` too.
Rename the second callback argument to `info` to make its purpose more
clear. Fix jsdoc comments, note that these comments are NOT shown
on http://apidocs.strongloop.com/.
This commit is dropping lodash in favour of hand-written implementation
based on ES5 Array methods. As a result, the size of the (unminified)
loopback browser bundle is decreased by approx 360KB.
ffcaa4e7 added a "data" argument to the callback function, which
shadowed the original data with the data returned by a connector.
Not all connectors are returning a data object though, in which case
the model instance ("this" object) is updated with wrong values.
This commit fixes the problem by renaming the second callback argument
to "unusedData".
"before save" hooks provide "ctx.isNewInstance" whenever "ctx.instance"
is set. Possible values:
- true for all CREATE operations
- false for all UPDATE operations
- undefined for "prototype.save"
"after save" hooks provide "ctx.isNewInstance" whenever "ctx.instance"
is set. Possible values:
- true after all CREATE operations
- false after all UPDATE operations
- undefined after "updateOrCreate" and "save"
Note: both "updateOrCreate" and "prototype.updateAttributes"
don't provide `ctx.instance` to "before save" hooks, therefore
`ctx.isNewInstance` it not provided either.
Before this commit, the following code would not work:
Change.updateOrCreate({...}, function(err, ch) {
// somewhere later, modify "ch" and save the changes
ch.save(cb);
});
"before delete" and "after delete" hooks receive `ctx.instance`
when a single model is being deleted.
"before save" hook receives `ctx.currentInstance` when triggered
by `prototype.updateAttributes()`.
Note that "after save" hook triggered by `prototype.updateAttributes()`
already provides `ctx.instance`.
List of deprecated hooks:
- beforeValidate
- afterValidate
- beforeCreate
- afterCreate
- beforeSave
- afterSave
- beforeUpdate
- afterUpdate
- beforeDestroy
- afterDestroy
Also add a lightweight browser version of "depd", because the "depd"
does not support browser and it is not trivial to fix that.
This commits adds a lightweight implementation of depd's "deprecate"
function.
