Is there a way to convert a number to a string in django's template? Or do I need to make a custom template tag. Something like:
{{ 1|stringify }} # '1'

You can use stringformat to convert a variable to a string:
{{ value|stringformat:"i" }}
See documentation for formatting options (the leading % should not be included).

You can indeed do that, but as I note in the comment, why would you? The output of
{{ value|stringformat:"i" }} is exactly the same as the output of {{ value }}.

@DanielRoseman: when writing an if statement the type does matter - so it may be needed to convert the type in the template and use that value in a comparison later.

Adding to this you cannot do something like
{% with var="this is an integer: "|add:an_int_variable %} without |stringformat:"i" on the an_int_variable first.You can use {{ value|slugify }} (https://docs.djangoproject.com/en/1.10/ref/templates/builtins/).

just create a new template tag
from django import template
register = template.Library()
@register.filter
def to_str(value):
"""converts int to string"""
return str(value)
and then go to your template and add in the top of the file
{% load to_str %}
{ number_variable|to_str %}
{% if item.type == content_type %}one would produce a true result the other would not.{% if item.type == content_type|add:0 %}to accomplish some kind of type casting.
