呈现时捕获到TypeError:__init __()获得了意外的关键字参数'use_decimal' [英] Caught TypeError while rendering: __init__() got an unexpected keyword argument 'use_decimal'

问题描述

在运行程序时，我收到以下错误消息

While running the program i am getting the following error message

Caught TypeError while rendering: __init__() got an unexpected keyword
argument 'use_decimal'

这是我的代码 我正在使用jquery 1.6.4

Here is my code i am using jquery 1.6.4

def load_charts(chart_list=None, render_to=''):
    embed_script = (
      '<script type="text/javascript">\n'
      'var _chartit_hco_array = %s;\n</script>\n'
      '<script src="%s" type="text/javascript">\n</script>')

    if chart_list is not None:
        if isinstance(chart_list, (Chart, PivotChart)):
            chart_list = [chart_list]
        chart_list = [c.hcoptions for c in chart_list]
        render_to_list = [s.strip() for s in render_to.split(',')]
        for hco, render_to in izip_longest(chart_list, render_to_list):
            if render_to:
                hco['chart']['renderTo'] = render_to
        embed_script = (embed_script % (simplejson.dumps(chart_list, 
                                                         use_decimal=True),
                                        CHART_LOADER_URL))
    else:
        embed_script = embed_script %((), CHART_LOADER_URL)
    return mark_safe(embed_script)

推荐答案

simplejson.dumps的签名为(请参阅

The signature of simplejson.dumps is (see documentation):

dumps(obj, skipkeys=False, ensure_ascii=True, 
      check_circular=True, allow_nan=True, cls=None)

如您所见，没有use_decimal参数...但是您是这样称呼它的:

as you can see there is no use_decimal parameter... yet you are calling it like this:

simplejson.dumps(chart_list, use_decimal=True)

---

编辑:实际上，进行了更多的挖掘工作其他文档.似乎use_decimal参数是在simplejson库的版本中添加的……我建议您将库的版本升级到最新的可用版本！

Actually a bit more digging brought up this other documentation. It seems that the use_decimal parameter was added somewhere along the version of simplejson library... I would suggest to upgrade you library version to the latest available one then!
