## Methods summary

`public static` | # `allow_show( mixed $allow = true )`
`public boolean` | # `canCreate( `Member` $member = null )` This function should return true if the current user can create new pages of this class. It can be overloaded to customise the security model for an application. This function should return true if the current user can create new pages of this class. It can be overloaded to customise the security model for an application. Denies permission if any of the following conditions is TRUE: canCreate() returns FALSE on any decorator $can_create is set to FALSE and the site is not in "dev mode" Use `Page::canAddChildren()` to control behaviour of creating children under this page. #### Parameters $member Member $member #### Returns `boolean` True if the current user can create pages on this class. #### Uses `mixed` ``DataObjectDecorator::canCreate()`` #### Overrides `SiteTree::canCreate`
`public `FieldSet`` | # `getCMSFields( )` Returns a FieldSet with which to create the CMS editing form. Returns a FieldSet with which to create the CMS editing form. You can override this in your child classes to add extra fields - first get the parent fields using parent::getCMSFields(), then use addFieldToTab() on the FieldSet. #### Returns ``FieldSet`` The fields to be displayed in the CMS. #### Overrides `Page::getCMSFields`
`public `DataObjectSet`` | # `Objects( )` Возвращает список объектов группы вообще можно было использовать AllChildren, но почему-то не работает Возвращает список объектов группы вообще можно было использовать AllChildren, но почему-то не работает #### Returns ``DataObjectSet`` DataObjectSet
`public` | # `onBeforeWrite( )` Event handler called before writing to the database. You can overload this to clean up or otherwise process data before writing it to the database. Don't forget to call parent::onBeforeWrite(), though! Event handler called before writing to the database. You can overload this to clean up or otherwise process data before writing it to the database. Don't forget to call parent::onBeforeWrite(), though! This called after $this->validate(), so you can be sure that your data is valid. #### Uses ``DataObjectDecorator::onBeforeWrite()`` #### Overrides `Page::onBeforeWrite`

## Properties summary

`public static boolean` | $can_be_root | # Controls whether a page can be in the root of the site tree. Controls whether a page can be in the root of the site tree.
`public static string` | $default_parent | # The default parent class for this page. The default parent class for this page.
`public static array` | $allowed_children | # Indicates what kind of children this page type can have. This can be an array of allowed child classes, or the string "none" - indicating that this page type can't have children. If a classname is prefixed by "*", such as "*Page", then only that class is allowed - no subclasses. Otherwise, the class and all its subclasses are allowed.

If a classname is prefixed by "*", such as "*Page", then only that class is allowed - no subclasses. Otherwise, the class and all its subclasses are allowed.
`public static boolean` | $show_as_page | #
`public static array` | $db | # Database field definitions. This is a map from field names to field type. The field type should be a class that extends . Database field definitions. This is a map from field names to field type. The field type should be a class that extends .
`public static array` | $has_one | # One-to-zero relationship defintion. This is a map of component name to data type. In order to turn this into a true one-to-one relationship you can add a `DataObject::$belongs_to` relationship on the child class. One-to-zero relationship defintion. This is a map of component name to data type. In order to turn this into a true one-to-one relationship you can add a `DataObject::$belongs_to` relationship on the child class. Note that you cannot have a has_one and belongs_to relationship with the same name.
`public static array` | $defaults | # Inserts standard column-values when a DataObject is instanciated. Does not insert default records `DataObject::$default_records`. This is a map from fieldname to default value. Inserts standard column-values when a DataObject is instanciated. Does not insert default records `DataObject::$default_records`. This is a map from fieldname to default value. If you would like to change a default value in a sub-class, just specify it. - If you would like to disable the default value given by a parent class, set the default value to 0,'',or false in your subclass. Setting it to null won't work.
`public static string` | $subpage_children | #
`public static array` | $yandexMarkers | #
