如何在Django中插入多个记录？

Question

视图.py

def input_transaksi(request):    
    kode_pem = dict(request.POST)['kode_pem']
    nominal = dict(request.POST)['nominal']
    rincian = Transaksi(kode_pem=kode_pem,nominal=nominal)
    rincian.save()

模型.py

^{pr2}$

然后我从这个表单输入数据

{% for t in trans %} #for looping form
    <from  method="post" action="{% url 'input_transaksi' %}" enctype="multipart/form-data">    
    <input type="hidden" name="kode_pem">           
        <input type="hidden" name="nominal">
    <input type="submit" value="Insert" class="btn btn-primary">
    </form>
{% endfor %}

但我得到一个错误：

Environment: Request Method: POST Request URL: http://localhost:8000/transaksi/input_transaksi

您好，您可以使用批量创建方法。在

此方法以高效的方式将提供的对象列表插入到数据库中（无论有多少个对象，通常只有1个查询）：

参考文档bulk-create
