TryCatchExtension

✓ from jinja_try_catch import TryCatchExtension

✗ from jinja_try_catch import TryExtension

Instantiate Jinja2 Environment with TryExtension; use {% try %}...{% catch %}...{% endtry %} blocks. Within catch block, `error` variable holds the exception message.

from jinja2 import Environment from jinja_try_catch import TryExtension env = Environment(extensions=[TryExtension()]) template = env.from_string(""" {% try %} {{ 1/0 }} {% catch %} Caught error: {{ error }} {% endtry %} """) print(template.render()) # Output: Caught error: division by zero

Debug

Known issues

gotcha`error` variable is only available inside the {% catch %} block. Referencing it outside will cause an undefined variable error.

fix

Only access `{{ error }}` within the {% catch %} block.

affects: all

deprecatedExtension registered via class name. Future versions may change the API for enabling extensions; check changelog.

fix

Continue using `TryExtension` class; no current deprecation but be aware of potential API changes.

affects: 0.1.x

gotchaCatch block catches all exceptions; no filtering by exception type is supported.

fix

Use conditional logic inside catch block if needed: `{% catch %}{% if 'specific' in error %}...{% endif %}{% endtry %}`.
