"""QWeb Xml templating engine
|
|
|
|
The templating engine use a very simple syntax based "magic" xml
|
|
attributes, to produce textual output (even non-xml).
|
|
|
|
The core magic attributes are:
|
|
|
|
flow attributes:
|
|
t-if t-foreach t-call
|
|
|
|
output attributes:
|
|
t-att t-raw t-esc t-trim
|
|
|
|
assignation attribute:
|
|
t-set
|
|
|
|
QWeb can be extended like any OpenERP model and new attributes can be
|
|
added.
|
|
|
|
If you need to customize t-fields rendering, subclass the ir.qweb.field
|
|
model (and its sub-models) then override :meth:`~.get_converter_for` to
|
|
fetch the right field converters for your qweb model.
|
|
|
|
Beware that if you need extensions or alterations which could be
|
|
incompatible with other subsystems, you should create a local object
|
|
inheriting from ``ir.qweb`` and customize that.
