如何在我的django表单上连接WMD编辑器？

如何将WMD编辑器连接到我的django表单上？

这是完整的Django小部件类:

class WMDEditor(forms.Textarea):

    def __init__(self, *args, **kwargs):
        attrs = kwargs.setdefault('attrs', {})
        if 'cols' not in attrs:
            attrs['cols'] = 58
        if 'rows' not in attrs:
            attrs['rows'] = 8
        super(WMDEditor, self).__init__(*args, **kwargs)

    def render(self, name, value, attrs=None):
        rendered = super(WMDEditor, self).render(name, value, attrs)
        return rendered + mark_safe(u'''
            ''' % settings.MEDIA_URL)

在表单定义中使用它text = forms.CharField(widget=WMDEditor).
