在Django框架中自定义模板过滤器的方法

def cut(value, arg):
  "Removes all values of arg from the given string"
  return value.replace(arg, '')

{{ somevariable|cut:" " }}

def lower(value): # Only one argument.
  "Converts a string into all lowercase"
  return value.lower()

register.filter('cut', cut)
register.filter('lower', lower)

@register.filter(name='cut')
def cut(value, arg):
  return value.replace(arg, '')

@register.filter
def lower(value):
  return value.lower()

from django import template

register = template.Library()

@register.filter(name='cut')
def cut(value, arg):
  return value.replace(arg, '')
