Template Lookup
|
|
===============
|
|
|
|
The discovery of templates is handled by Mako, and is configurable.
|
|
|
|
WuttaWeb comes with all templates it needs, in the path designated as
|
|
``wuttaweb:templates``.
|
|
|
|
When the app renders a page, it invokes the Mako lookup logic, which
|
|
searches one or more folders and returns the first matching file it
|
|
encounters. By default ``wuttaweb:templates`` is the only place it
|
|
looks.
|
|
|
|
A template is searched for by "name" but it is more path-like, e.g.
|
|
``/page.mako`` or ``/master/index.mako`` etc. So for example the file
|
|
at ``wuttaweb:templates/home.mako`` is used for home page (using
|
|
lookup name ``/home.mako``) by default.

Overriding the Search Paths
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The basic idea is to give it a list of paths it should search when
|
|
trying to find a template. The first template file found for a given
|
|
search name is used and no further search is done for that name.
|
|
|
|
You can define the Mako lookup sequence in your ``web.conf`` as
|
|
follows:
|
|
|
|
.. code-block:: ini
|
|
|
|
[app:main]
|
|
mako.directories =
|
|
/random/path/on/disk
|
|
poser.web:templates
|
|
wuttaweb:templates
|
|
|
|
This setting is interpreted by ``pyramid_mako`` (`docs`_).
|
|
|
|
.. _docs: https://docs.pylonsproject.org/projects/pyramid_mako/en/latest/index.html#mako-directories
|
|
|
|
Here ``wuttaweb:templates/home.mako`` would still be used by default
|
|
for home page, *unless* e.g. ``/random/path/on/disk/home.mako``
|
|
existed in which case that would be used.
|
|
|
|
Each path can have an arbitrary set of templates, they will
|
|
effectively be combined to a single set by the app, with the
|
|
definition order determining search priority.
|
|
|
|
If you are already using a custom ``app.main()`` function for
|
|
constructing the web app during startup, it may be a good idea to
|
|
change the *default* search paths to include your package.
|
|
|
|
Setup for custom ``app.main()`` is beyond the scope here, but assuming
|
|
you *do* already have one, this is what it looks like::
|
|
|
|
from wuttaweb import app as base
|
|
|
|
def main(global_config, **settings):
|
|
|
|
# nb. set the *default* mako search paths; however config can
|
|
# still override with method shown above
|
|
settings.setdefault('mako.directories', ['poser.web:templates',
|
|
'wuttaweb:templates'])
|
|
|
|
return base.main(global_config, **settings)
|
