Class PaginatorComponent
This component is used to handle automatic model data pagination. The primary way to use this component is to call the paginate() method. There is a convenience wrapper on Controller as well.
Configuring pagination
You configure pagination when calling paginate(). See that method for more details.

mergeOptions() ¶ public
mergeOptions(string $alias, array $settings): arrayMerges the various options that Pagination uses. Pulls settings together from the following places:
- General pagination settings
- Model specific settings.
- Request parameters
The result of this method is the aggregate of all the option sets combined together. You can change
config value whitelist to modify which options/values can be set using request parameters.
Parameters
- 
                string$alias
- Model alias being paginated, if the general settings has a key with this value that key's settings will be used for pagination instead of the general ones. 
- 
                array$settings
- The settings to merge with the request data. 
Returns
arrayArray of merged options.
paginate() ¶ public
paginate(Cake\Datasource\RepositoryInterface|Cake\Datasource\QueryInterface $object, array $settings = []): Cake\Datasource\ResultSetInterfaceHandles automatic pagination of model records.
Configuring pagination
When calling paginate() you can use the $settings parameter to pass in pagination settings.
These settings are used to build the queries made and control other pagination settings.
If your settings contain a key with the current table's alias. The data inside that key will be used. Otherwise the top level configuration will be used.
 $settings = [
   'limit' => 20,
   'maxLimit' => 100
 ];
 $results = $paginator->paginate($table, $settings);The above settings will be used to paginate any Table. You can configure Table specific settings by keying the settings with the Table alias.
 $settings = [
   'Articles' => [
     'limit' => 20,
     'maxLimit' => 100
   ],
   'Comments' => [ ... ]
 ];
 $results = $paginator->paginate($table, $settings);This would allow you to have different pagination settings for Articles and Comments tables.
Controlling sort fields
By default CakePHP will automatically allow sorting on any column on the table object being
paginated. Often times you will want to allow sorting on either associated columns or calculated
fields. In these cases you will need to define a whitelist of all the columns you wish to allow
sorting on. You can define the whitelist in the $settings parameter:
$settings = [
  'Articles' => [
    'finder' => 'custom',
    'sortWhitelist' => ['title', 'author_id', 'comment_count'],
  ]
];Passing an empty array as whitelist disallows sorting altogether.
Paginating with custom finders
You can paginate with any find type defined on your table using the finder option.
 $settings = [
   'Articles' => [
     'finder' => 'popular'
   ]
 ];
 $results = $paginator->paginate($table, $settings);Would paginate using the find('popular') method.
You can also pass an already created instance of a query to this method:
$query = $this->Articles->find('popular')->matching('Tags', function ($q) {
  return $q->where(['name' => 'CakePHP'])
});
$results = $paginator->paginate($query);Scoping Request parameters
By using request parameter scopes you can paginate multiple queries in the same controller action:
$articles = $paginator->paginate($articlesQuery, ['scope' => 'articles']);
$tags = $paginator->paginate($tagsQuery, ['scope' => 'tags']);Each of the above queries will use different query string parameter sets for pagination data. An example URL paginating both results would be:
/dashboard?articles[page]=1&tags[page]=2Parameters
- 
                Cake\Datasource\RepositoryInterface|Cake\Datasource\QueryInterface$object
- The table or query to paginate. 
- 
                array$settings optional
- The settings/configuration used for pagination. 
Returns
Cake\Datasource\ResultSetInterfaceQuery results

$_configInitialized ¶ protected
Whether the config property has already been configured with defaults
Type
bool$_defaultConfig ¶ protected
Default pagination settings.
When calling paginate() these settings will be merged with the configuration you provide.

- limit- The initial number of items per page. Defaults to 20.
- page- The starting page, defaults to 1.
- whitelist- A list of parameters users are allowed to set using request parameters. Modifying this list will allow users to have more influence over pagination, be careful with what you permit.
