Can you parameterize a template tag library on template directory?-CodePudding

Let's say I'm writing a form template tag library for Django, but want to be able to render both Bootstrap and UIKit forms.

The Python code will be identical, except for the template reference. Simplified

@register.inclusion_tag('myforms/bootstrap/formrow.html')
def form_row(fieldname, labelpos, labelsize, widgetsize):
    return {...}

vs.

@register.inclusion_tag('myforms/uikit/formrow.html')
def form_row(fieldname, labelpos, labelsize, widgetsize):
    return {...}

I would like to prevent the duplication of the python code, but the @register.inclusion_tag(..) function runs very early in the Django lifecycle, so I'm not sure if it is possible, or how to do it..?

CodePudding user response：

From the documentation it's possible to register the inclusion tag using a django.template.Template instance, which means that you can do the following,

# Pseudo code
from django.template.loader import get_template

bootstrap = get_template('myforms/bootstrap/formrow.html')
uikit = get_template('myforms/uikit/formrow.html')

register.inclusion_tag(bootstrap)(re_usable_form_row_function)
register.inclusion_tag(uikit)(re_usable_form_row_function)
