【问题描述】：

我正在使用 django 框架，我找到了一种方法来存储我通过 RPC 调用收到的数据。此数据遵循 JSON 格式：

"header":["data_enviament","nom_auditor","matricula","bastidor"],"data":["data_enviament":"05/1/2014","nom_auditor":"Brutus Brutus, Marc","matricula":"1234FRX","bastidor":"192891478kjhda","data_enviament":"05/2/2014","nom_auditor":"Pepito Rudolf, Margarita","matricula":"2234FRX","bastidor":"192891478kjhda","data_enviament":"05/5/2014","nom_auditor":"Patrick Linda, Judith","matricula":"5234FRX","bastidor":"192891478kjhda"],"count":2

我将这些数据存储到一个矩阵中（在控制器点），代码是：

for i in range(len(tabla['header'])):
        array[0][i] = tabla['header'][i]


    x = 1
    for data in tabla['data']:
        for i in range(len(tabla['header'])):
            array[x][i] = data[array[0][i]]
        x = x + 1

然后我通过渲染函数将这些数据解析到模板中并表示成一个html表格。 我做得很好，或者可能有其他方法可以做得更好？

【参考方案1】：

您可以将数据转换为列表的列表，并根据标题保持项目的顺序。

从 shell 演示：

>>> from django.template import Template, Context
>>> data = "header":["data_enviament","nom_auditor","matricula","bastidor"],"data":["data_enviament":"05/1/2014","nom_auditor":"Brutus Brutus, Marc","matricula":"1234FRX","bastidor":"192891478kjhda","data_enviament":"05/2/2014","nom_auditor":"Pepito Rudolf, Margarita","matricula":"2234FRX","bastidor":"192891478kjhda","data_enviament":"05/5/2014","nom_auditor":"Patrick Linda, Judith","matricula":"5234FRX","bastidor":"192891478kjhda"],"count":2
>>>
>>> data = [[item[header] for header in data['header']] for item in data['data']]
>>> c = Context('data': data)
>>> template = """
    <table>
        % for row in data %
            <tr>
            % for item in row %
                <td> item </td>
            % endfor %
            </tr>
        % endfor %
    </table>
"""
>>> t = Template(template)
>>> print t.render(c)

    <table>

            <tr>

                <td>05/1/2014</td>

                <td>Brutus Brutus, Marc</td>

                <td>1234FRX</td>

                <td>192891478kjhda</td>

            </tr>

            <tr>

                <td>05/2/2014</td>

                <td>Pepito Rudolf, Margarita</td>

                <td>2234FRX</td>

                <td>192891478kjhda</td>

            </tr>

            <tr>

                <td>05/5/2014</td>

                <td>Patrick Linda, Judith</td>

                <td>5234FRX</td>

                <td>192891478kjhda</td>

            </tr>

    </table>
