Question

>>> from factories import PageFactory
>>> p = PageFactory.create()
>>> p.name
u'Hey There, Im Jack697'
>>> from django.template import Template, Context
>>> t = Template("{% load inplace_edit %} {% inplace_edit page.name %}")
>>> t.render(Context({'page': p}))

inplace_edit标记，这是第三方包：

class InplaceEditNode(RenderWithArgsAndKwargsNode):

    def prepare_context(self, args, kwargs, context):
        expression_to_show = args[0]
        tokens_to_show = expression_to_show.split('|')
        obj_field_name, filters_to_show = tokens_to_show[0], '|'.join(tokens_to_show[1:])
        obj_field_name_split = obj_field_name.split(".")
        obj_context = '.'.join(obj_field_name_split[:-1])
        field_name = obj_field_name_split[-1]
        obj = Variable(obj_context).resolve(context)
        adaptor = kwargs.get('adaptor', None)
        class_adaptor = get_adaptor_class(adaptor, obj, field_name)
        request = context.get('request')

        config = class_adaptor.get_config(request, **kwargs)

        adaptor_field = class_adaptor(request, obj, field_name,
                                      filters_to_show,
                                      config)

        context = {
            'adaptor_field': adaptor_field,
        }
        return context


@register.tag
def inplace_edit(parser, token):
    args, kwargs = parse_args_kwargs(parser, token)
    return InplaceEditNode(args, kwargs, 'inplaceeditform/inplace_edit.html')

此模板标记在其他模板中使用相同的Page模型。我基本上想知道“Django模板标签会出现这样的常见原因吗？”

Answer 1

从documentation您可以看到需要引用标签的参数。

{% inplace_edit  "OBJ.FIELD_NAME" %}
{% inplace_edit  "OBJ.FIELD_NAME|FILTER1|FILTER2|...|FILTERN" %}

引用参数将解决问题。

为什么在加载这个Django模板时我得到“IndexError：字符串索引超出范围”？
