jinja-try-catch

A Jinja2 extension providing exception handling within templates.

{%- try -%}
  {{ 1 / 0 }}
{%- catch -%}
  Can't divide by zero!
{%- endtry -%}

Can't divide by zero!

This extension works in both sync and async environments, as well as the native variants, too.

Quickstart

pip install jinja-try-catch

And add the TryCatchExtension to your Environment extensions list:

import jinja2
from jinja_try_catch import TryCatchExtension

jinja_env = jinja2.Environment(extensions=[TryCatchExtension])

Simply omit the {% catch %} to silently swallow exceptions

{%- try -%}
  {{ 1 / 0 }}
{%- endtry -%}

Define a {% catch %} to render something else if an exception is raised

{%- try -%}
  {{ 1 / 0 }}
{%- catch -%}
  There are infinite zeroes, duh
{%- endtry -%}

There are infinite zeroes, duh

The raised exception is exposed within the {% catch %} through the {{ exception }} variable

{%- try -%}
  {{ 1 / 0 }}
{%- catch -%}
  Uh-oh, an error occurred:
  {{ exception.__class__.__name__ }}: {{ exception }}
{%- endtry -%}

Uh-oh, an error occurred:
  ZeroDivisionError: division by zero
