reviewboard.datagrids.sidebar¶

Sidebar item management for datagrids.

class BaseSidebarItem(sidebar, datagrid)[source]¶

Bases: object

Base class for an item on the sidebar of a datagrid.

Items can optionally have labels and counts associated with them. Depending on the subclass, it may also be able to nest items.

They may also have custom templates, for more advanced rendering.

See SidebarNavItem and BaseSidebarSection for the common types of sidebar items.

datagrid¶

The datagrid containing this item.

Type:	djblets.datagrid.grids.DataGrid

sidebar¶

The sidebar containing this item.

Type:	Sidebar

template_name = None[source]¶

The template to use for rendering this item in the sidebar.

label = None[source]¶

The displayed label for the item.

icon_name = None[source]¶

The name of the optional CSS icon to use beside the label.

view_id = None[source]¶

The datagrid “view” to link to when clicking this item.

This corresponds to the ?view= parameter passed to the datagrid page.

view_args = None[source]¶

Additional key/values to pass to the URL when clicking this item.

If provided, this must be a dictionary of keys and values for the URL. The keys and values will be automatically URL-encoded.

Parameters:	sidebar (Sidebar) – The sidebar containing this item. datagrid (djblets.datagrid.grids.DataGrid) – The datagrid containing this item.

get_url()[source]¶

Return the URL used when clicking the item.

By default, this builds a URL to the parent datagrid using the view_id and view_args attributes. If they are not set, then the item won’t be clickable.

Return type:	int

is_visible()[source]¶

Return whether the item is visible.

By default, an item is visible. Subclasses can override this to control visibility.

Returns:	True if the item is visible. False if it’s hidden.
Return type:	bool

is_active()[source]¶

Return whether the item is currently active.

The item will be active if the current page matches the URL associated with the item.

Return type:	bool

render()[source]¶

Render the item.

Returns:	The rendered HTML for the item.
Return type:	django.utils.safestring.SafeText

Subclasses can override this to define a section and provide items listed in the section.

Sections can optionally be clickable and display a count.

template_name = u'datagrids/sidebar_section.html'[source]¶

Return the items displayed in this section.

Subclasses must override this and return or yield the items to be displayed.

Returns:	The list of items to display in the section.
Return type:	list of BaseSidebarItem

is_visible()[source]¶

Return type:	bool

get_extra_context()[source]¶

Return extra context for the section.

Subclasses that override this method must call the parent method.
