如何向django表单小部件添加其他上下文

from django.forms import Widget

class CustomWidget(Widget):
    def __init__(self, attrs=None, context=None):
        self.context = context
        super().__init__(attrs=attrs)

from django.forms import Widget

class CustomWidget(Widget):
    def __init__(self, attrs=None, context=None):
        self.context = context
        super().__init__(attrs=attrs)

    def render(self, name, value, attrs=None, renderer=None):
        # 在这里可以使用self.context访问到上下文数据
        # 可以根据需要自定义渲染逻辑
        return super().render(name, value, attrs=attrs, renderer=renderer)

from django import forms

class MyForm(forms.Form):
    my_field = forms.CharField(widget=CustomWidget(context={'key': 'value'}))
