AbstractCrudManager
Abstract
This is an abstract class serving as the base for the CrudManager class. It implements basic mechanisms to organize batch communication with a server. Yet it does not contain methods related to data transfer nor encoding. These methods are to be provided in sub-classes by consuming the appropriate mixins.
For example, this is how the class can be used to implement an JSON encoding system:
// let's make new CrudManager using AJAX as a transport system and JSON for encoding
class MyCrudManager extends JsonEncode(AjaxTransport(AbstractCrudManager)) {
}
Data transfer and encoding methods
These are methods that must be provided by subclasses of this class:

Configs
Configs are options you supply in a configuration object when creating an instance of this class-
trueto automatically persist store changes after edits are made in any of the stores monitored. Please note that sync request will not be invoked immediately but only after autoSyncTimeout interval. -
The timeout in milliseconds to wait before persisting changes to the server. Used when autoSync is set to
true. -
Specify as
trueto force sync requests to be sent when callingsync(), even if there are no local changes. Useful in a polling scenario, to keep client up to date with the backend.Has a corresponding runtime forceSync property.
-
Set to
trueto make STM ignore changes coming from the backend. This will allow user to only undo redo local changes.Has a corresponding runtime ignoreRemoteChangesInSTM property.
-
Field name to be used to transfer a phantom record identifier.
-
Field name to be used to transfer a phantom parent record identifier.
-
Trueto reset identifiers (defined byidFieldconfig) of phantom records before submitting them to the server. -
When
truetreats parsed responses withoutsuccessproperty as successful. In this mode a parsed response is treated as invalid if it has explicitly setsuccess : false. -
When
trueforces the CRUD manager to process responses depending on theirtypeattribute. Soloadrequest may be responded withsyncresponse for example. Can be used for smart server logic allowing the server to decide when it's better to respond with a complete data set (loadresponse) or it's enough to return just a delta (syncresponse). -
trueto write all fields from the record to the server. If set tofalseit will only send the fields that were modified. Note that any fields that have persist set tofalsewill still be ignored and fields having alwaysWrite set totruewill always be included. -
Internal listeners, that cannot be removed by the user.
Properties
Properties are getters/setters or publicly accessible variables on this class-
Identifies an object as an instance of AbstractCrudManager class, or subclass thereof.
-
Identifies an object as an instance of AbstractCrudManagerMixin class, or subclass thereof.
-
Identifies an object as an instance of AbstractCrudManagerValidation class, or subclass thereof.
-
Identifies an object as an instance of Delayable class, or subclass thereof.
-
Identifies an object as an instance of Events class, or subclass thereof.
-
A class property getter for the default values of internal properties for this class.
-
A list of registered stores whose server communication will be collected into a single batch. Each store is represented by a store descriptor.
Has a corresponding stores config.
-
Returns the data from all CrudManager
crudStoresin a format that can be consumed byinlineData. -
An empty array that can be used as a default value.
-
An empty object that can be used as a default value.
-
A list of registered stores whose server communication will be collected into a single batch. Each store is represented by a store descriptor.
Has a corresponding crudStores config.
-
Specify as
trueto force sync requests to be sent when callingsync(), even if there are no local changes. Useful in a polling scenario, to keep client up to date with the backend.Has a corresponding forceSync config.
-
Set to
trueto make STM ignore changes coming from the backend. This will allow user to only undo redo local changes.Has a corresponding ignoreRemoteChangesInSTM config.
-
Returns
trueif changes tracking is suspended -
Returns true if the crud manager is currently loading data
-
Returns true if the crud manager is currently syncing data
-
Returns true if the crud manager is currently loading data
-
Generates unique request identifier.
-
An array of stores presenting an alternative sync responses apply order. Each store is represented by a store descriptor.
Has a corresponding syncApplySequence config.
-
Identifies an object as an instance of AbstractCrudManager class, or subclass thereof.
-
Returns a copy of the full configuration which was used to configure this object.
-
This property is set to
truebefore theconstructorreturns. -
This property is set to
trueon entry to the destroy method. It remains on the objects after returning fromdestroy(). If isDestroyed istrue, this property will also betrue, so there is no need to test for both (for example,comp.isDestroying || comp.isDestroyed).
Functions
Functions are methods available for calling on the class-
This optional class method is called when a class is mixed in using the mixin() method.
-
Registers this class type with its Factory
-
Accepts all changes in all stores, resets the modification tracking:
- Clears change tracking for all records
- Clears added
- Clears modified
- Clears removed Leaves the store in an "unmodified" state.
-
Reverts all changes in all stores and re-inserts any records that were removed locally. Any new uncommitted records will be removed.
-
Suspends automatic sync upon store changes. Can be called multiple times (it uses an internal counter).
-
Suspends hasChanges and noChanges events.
-
Internal function used to hook destroy() calls when using thisObj
-
Internal function used restore hooked destroy() calls when using thisObj
-
Auto detaches listeners registered from start, if set as detachable
-
Internal function used to run a callback function after an event is triggered
-
Removes all listeners registered to this object by the application.
