Class ShadowTableStrategy

This class provides a way to translate dynamic data by keeping translations in a separate shadow table where each row corresponds to a row of primary table.

Namespace: Cake\ORM\Behavior\Translate

Properties summary

  • $_config protected
    array

    Runtime config

  • $_configInitialized protected
    bool

    Whether the config property has already been configured with defaults

  • $_defaultConfig protected
    array

    Default config

  • $_tableLocator protected
    \Cake\ORM\Locator\LocatorInterface|null

    Table locator instance

  • $locale protected
    string|null

    The locale name that will be used to override fields in the bound table from the translations table

  • $table protected
    \Cake\ORM\Table

    Table instance

Method Summary

  • __construct() public

    Constructor

  • _configDelete() protected

    Deletes a single config key.

  • _configRead() protected

    Reads a config key.

  • _configWrite() protected

    Writes a config key.

  • addFieldsToQuery() protected

    Add translation fields to query.

  • afterSave() public

    Unsets the temporary _i18n property after the entity has been saved

    Callback method that listens to the beforeFind event in the bound table. It modifies the passed query by eager loading the translated fields and adding a formatter to copy the values into the main table records.

    Helper method used to generated multiple translated field entities out of the data found in the _translations property in the passed entity. The result will be put into its _i18n property.

  • configShallow() public

    Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.

  • getConfig() public

    Returns the config.

buildMarshalMap() public 

buildMarshalMap(\Cake\ORM\Marshaller $marshaller, array $map, array $options)

Build a set of properties that should be included in the marshalling process.

Add in _translations marshalling handlers. You can disable marshalling of translations by setting 'translations' => false in the options provided to Table::newEntity() or Table::patchEntity().

Parameters

\Cake\ORM\Marshaller $marshaller

The marhshaller of the table the behavior is attached to.

array $map

Parameters

\Cake\Datasource\EntityInterface $entity

Entity.

configShallow() public 

configShallow(mixed $key, mixed $value)

Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.

Setting a specific value:

$this->configShallow('key', $value);

Setting a nested value:

$this->configShallow('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->configShallow(['one' => 'value', 'another' => 'value']);

Parameters

string|array $key

The key to set, or a complete array of configs.

mixed|null $value optional

The value to set.

Returns

$this

getConfig() public 

getConfig(?string $key, mixed $default)

Returns the config.

Usage

Reading the whole config:

$this->getConfig();

Reading a specific value:

$this->getConfig('key');

Reading a nested value:

$this->getConfig('some.nested.key');

Reading with default value:

$this->getConfig('some-key', 'default-value');

Parameters

string|null $key optional

The key to get or null for the whole config.

mixed $default optional

The return value when the key does not exist.

Returns

mixed

Configuration data at the named key or null if the key does not exist.

getConfigOrFail() public 

getConfigOrFail(string $key)

Returns the config for this specific key.

The config value for this key must exist, it can never be null.

Parameters

string $key

The key to get.

Returns

mixed

Configuration data at the named key

Throws

InvalidArgumentException

getLocale() public 

getLocale()

Returns the current locale.

If no locale has been explicitly set via setLocale(), this method will return the currently configured global locale.

Returns

string

getTableLocator() public 

getTableLocator()

Gets the table locator.

Returns

\Cake\ORM\Locator\LocatorInterface

Results to modify.

Returns

\Cake\Collection\CollectionInterface

iterateClause() protected 

iterateClause(mixed $query, mixed $name, mixed $config)

Iterate over a clause to alias fields.

The objective here is to transparently prevent ambiguous field errors by prefixing fields with the appropriate table alias. This method currently expects to receive an order clause only.

Parameters

\Cake\ORM\Query $query

the query to check.

string $name optional

The clause name.

array $config optional

The config to use for adding fields.

Returns

bool

Whether a join to the translation table is required.

mainFields() protected 

mainFields()

Lazy define and return the main table fields.

Returns

array

rowMapper() protected 

rowMapper(mixed $results, mixed $locale)

Modifies the results from a table find in order to merge the translated fields into each entity for a given locale.

Parameters

\Cake\Datasource\ResultSetInterface $results

Results to map.

string $locale

Locale string

Returns

\Cake\Collection\CollectionInterface

setConfig() public 

setConfig(mixed $key, mixed $value, mixed $merge)

Sets the config.

Usage

Setting a specific value:

$this->setConfig('key', $value);

Setting a nested value:

$this->setConfig('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->setConfig(['one' => 'value', 'another' => 'value']);

Parameters

string|array $key

The key to set, or a complete array of configs.

mixed|null $value optional

The value to set.

bool $merge optional

Whether to recursively merge or overwrite existing config, defaults to true.

Returns

$this

Throws

Cake\Core\Exception\Exception
When trying to set a key that is invalid.

setLocale() public 

setLocale(?string $locale)

Sets the locale to be used.

When fetching records, the content for the locale set via this method, and likewise when saving data, it will save the data in that locale.

Note that in case an entity has a _locale property set, that locale will win over the locale set via this method (and over the globally configured one for that matter)!

Parameters

string|null $locale

The locale to use for fetching and saving records. Pass null in order to unset the current locale, and to make the behavior fall back to using the globally configured locale.

Returns

$this

setTableLocator() public 

setTableLocator(\Cake\ORM\Locator\LocatorInterface $tableLocator)

Sets the table locator.

Parameters

\Cake\ORM\Locator\LocatorInterface $tableLocator

LocatorInterface instance.

Returns

$this

setupAssociations() protected 

setupAssociations()

Create a hasMany association for all records.

Don't create a hasOne association here as the join conditions are modified in before find - so create/modify it there.

translatedFields() protected 

translatedFields()

Lazy define and return the translation table fields.

Returns

array

translationField() public 

translationField(string $field)

Returns a fully aliased field name for translated fields.

If the requested field is configured as a translation field, field with an alias of a corresponding association is returned. Table-aliased field name is returned for all other fields.

Parameters

string $field

Field name to be aliased.

Returns

string

traverseClause() protected 

traverseClause(mixed $query, mixed $name, mixed $config)

Traverse over a clause to alias fields.

The objective here is to transparently prevent ambiguous field errors by prefixing fields with the appropriate table alias. This method currently expects to receive a where clause only.

Parameters

\Cake\ORM\Query $query

the query to check.

string $name optional

The clause name.

array $config optional

The config to use for adding fields.

Returns

bool

Whether a join to the translation table is required.

unsetEmptyFields() protected 

unsetEmptyFields(mixed $entity)

Unset empty translations to avoid persistence.

Should only be called if $this->_config['allowEmptyTranslations'] is false.

Parameters

\Cake\Datasource\EntityInterface $entity

The entity to check for empty translations fields inside.
