player 0.6.1

player

player allows to address templates with two parameters, category and name. Also it is possible to use set of directories for each layer, in that case player searches templates in each directory. It allows to override templates without changing code. For example form library can define layer field:

>> ls ./fields/
.. bool.pt
.. file.pt
...
.. textarea.pt

In your application you can override any of this template by defining new layer for field category:

>> ls ./myproject/fields/
.. bool.pt

Usually top level directory is a category and file in directory is template. For example ‘form:view.lt’:

`form` - layer category
`view` - template name
`.lt`  - custom pyramid renderer factory

Layer can to be defined with add_layer config directive:

>> config = Configurator()
.. config.include('player')
..
.. config.add_layer('form', path='./path_to_form_dirctory/form/')

form directory can contain any template:

>> ./form/
..   view.pt
..   actions.jinja2

It is possible to use any of this templates as pyramid renderer path:

>> config.add_view(
..     name='view.html',
..     renderer='form:view.lt')

or :

>> config.add_view(
..     name='actions.html',
..     renderer='form:actions.lt')

It is possible to run python code before rendering template. There are add_tmpl_filter directive and player.tmpl_filter decorator:

>> def form_actions(context, request):
..     return {'url': ...}

>> config.add_tmpl_filter('form:actions', form_action, name='custom')

or:

>> import player

>> @player.tmpl_filter('form:actions', name='custom')
.. def form_actions(context, request):
..     return {'url': ...}

form_actions function gets call just before rendering template. Layer has to be defined with add_layer directve before registering template filter function.

>> config.add_layer('form', 'custom', path='path_to_form_directory_2/form')

>> ./another_path/form/
..   view.jinja2

>> config.add_layer('fields', 'custom', 'mypackage:fields')

>> .mypackage/fields/
..    bool.pt

..  ${structure: request.render_tmpl('form:actions')
