Question

Trying to follow the Django Inclusion Tag documentation to create a custom template tag, but getting a template syntax error on line 6: def types(Information).

from django import template

register = template.Library()

@register.inclusion_tag('edit.html')
def types(Information)
    informations = Information.objects.all()
    return {'informations': informations}

The templatetag.py file is within the /templatetags directory.

The model for Information:

class Information(models.Model):
    name = models.CharField(max_length=20)
    models = models.ManyToManyField('Model')

The template (edit.html):

{% load templatetag %}
<ul>
   {% for information in informations %}
      <li> {{ information }} </li>
   {% endfor %}
</ul>

Am I misunderstanding how to create the inclusion tag and objects? Thanks for any advice.

Answer 1

Well, not surprisingly, you have a syntax error. Function definitions, like anything that starts a block in Python, need to have a colon at the end:

def types(information):

Also note that for some reason you’ve named your argument Information, which will hide the class Information – whatever object you pass as the actual parameter will be used as the base for the objects.all() query, which is unlikely to work.
