plone.directives.tiles 1.2

Usage

A basic tile is configured like this:

from five import grok
from plone.directives import tiles

from my.package import MyMessageFactory as _
from my.package.interfaces import IMyTileSchema

class MyTile(tiles.Tile):
    grok.context(IContext)
    grok.require('zope2.View')

    grok.name('my.tile')
    grok.title(_(u"My title"))
    grok.description(_(u"My description"))

    tiles.add_permission('mypackage.AddMyTile')
    tiles.schema(IMyTileSchema)

Notes

• A persistent tile can be configured by deriving from PersistentTile instead of Tile.

• The context(), requires(), name(), and layer() directives are used in the same way as they are for a view derived from grok.View.

• Templates are associated using the same semantics as are used for views. For example, a tile in mytiles.py defined in the class MyTile would be associated with a template mytiles_templates/mytile.pt by default.

• Unlike a view, the name() directive is required and should give a dotted name for the tile by convention.

• Dictionary key access (__getitem__()) is defined to work as it does in a tile. In a standard grokked view, it will retrieve a macro from the template. In a tile, it is used as a traversal hook to set the tile id, and subsequently to look up views on the tile. See plone.tiles for details.

• Similarly, standard grokked views have a url() method which can be used to construct a URL, possibly with query string parameters. For grokked tiles, this is replaced by a url read-only property, which returns the canonical tile URL, as per plone.tiles.
