I've written a custom template tag to replace parts of a value:
{{{
@register.simple_tag
def string_replace(value, old, new):
return value.replace(old, new)
}}}
And I'm using it to replace newline characters with commas in a user's
address:
{{{
{% string_replace user.address '\r\n' ',' %}
}}}
However, this doesn't work.
The reason is that when Django loads a template using Python's
`file.read()` function, the backslashes get escaped which means `\r\n`
becomes `\\r\\n`.
So, the `string_replace` tag actually receives `\\r\\n` instead of `\r\n`.
This also affects other tags as well.
Shouldn't Django pass the original string argument to the template tag as
intended?
