I tried the above template_tag and it worked fine for me, maybe you're
doing something wrong in the template?
My best guess for why "__init__" would be called and not "render" is
that the template_tag is not getting rendered due to some other logic
in the template. All of these examples below will cause __init__ to
be called, but not render for "my_template_tag":
1. Failed if statement:
{% if 0 %}{% my_template_tag %}{% endif %}
2. For loop on an empty list (or string):
{% for x in "" %}{% my_template_tag %}{% endfor %}
3. Block that gets replaced by a child template:
/base.html:
{% block test %}{% my_template_tag %}{% endblock %}
/my_template.html:
{% block test %}OVERWRITE TEST BLOCK!{% endblock %}
If that's not the case, then you'll need to provide more information—
how's it done in the template? what version of django? etc.
Separately, if you're resolving arguments to a template_tag, I'd
recommend using the template.Variable and .resolve(context) construct,
this will resolve plain text that you put in quotes and also variables
that are in the context:
