如何避免"超出GET/POST参数的数量"错误？

Question

我在Django网站上创建了一个自定义管理页面,只允许管理员使用,并且能够更改对象及其属性.对象的数量很多(确切地说是9220),在管理页面上,有相同数量的输入字段作为该模型中的对象.

这是代码:

<form action="{% url 'Home:AdminPrices' %}" id="mainForm" method="post">
{% csrf_token %}
{% for item in prices %}
    <ul class="row" style="width: 100%;padding: 0;background-color: white;height: 100px;display: flex;justify-content: left;white-space: nowrap;margin-bottom: 0;margin-top: 0;">
        <div style="width: 33.333333333333336%;background-color: white;display:  block;color: black;font-size: 0.8em;white-space: nowrap;text-align: center;font-family: 'Lato';padding-top: 25px;">{{ item.hashname }}</div>
        <div style="width: 33.333333333333336%;background-color: white;display:  block;color: black;font-size: 1.2em;text-align: center;font-family: 'Lato';padding-top: 25px;">{{ item.sug }}</div>
        <div style="width: 33.333333333333336%;background-color: white;display:  block;color: black;font-size: 1.2em;text-align: center;font-family: 'Lato';"><input type="number" value="{{ item.actual }}" name="prices_{{ item.actual }}" style="width: 100%;height: 100%;padding-bottom: 25px;background-color: white;border: 0;color: black;font-size: 1.2em;text-align: center;font-family: 'Lato';"></input></div>
    </ul>
{% endfor %}
    <input type="submit" id="mainSubmit" style="display: none;" name="submitPrices"></input>
</form>
<div onclick="document.getElementById('mainForm').submit();" style="background-color: black;border-radius: 5px;position: fixed;display: block;height: 50px;width: 200px;bottom: 0;left:0;right:0;margin: 0 auto;color: white;font-size: 1.5em;text-align: center;padding-top: 12.5px;cursor: pointer;">Submit</div>

按下提交按钮后,网站崩溃并提示输出此错误:

我不太确定如何避免它,我可以更改设置并为此视图专门设置不同的限制吗？或者我可以将所有这些字段作为一个列表提交？如果没有,那么可能是什么解决方案呢？我可以指定DATA_UPLOAD_MAX_NUMBER_FIELDS某些视图的设置吗？提前致谢.

Answer 1

Django的文档指出除了设置之外的任何地方都不应该更改设置:

https://docs.djangoproject.com/en/1.11/topics/settings/#altering-settings-at-runtime

正如您所提到的,解决方案是增加DATA_UPLOAD_MAX_NUMBER_FIELDS设置的大小.祝好运!
