Jinja2 Script

Introduction

In ERB, custom functions can be written in the template. However with jinja2, the functions should be written in python, and must be included in the rendering environment.

Use Script Block

{% script modulename %}
  # Your Python Code that should be in .py
{% endscript %}

Define your python codes in script block. This is compiled before actual run starts.

To use compiled block, do it as following:

{{module.functions_you_defined()}}
{{module.values_you_defined()}}
{{module.function_with_arguments(1)}}
{{module.function_with_arguments_at_render(x)}}

How to use

from jinja_script_block import ScriptBlockExtension
from jinja2 import Environment

env = Environment(extensions=[ScriptBlockExtension])

env.from_string('''
{% script mymodule %}
class MyClass:
  containers = []
{% endscript%}
''')
