UpdateView问题：清理的URL中传递的数据不在实例中

Question

我的更新视图有问题，但我不知道为什么会发生。因此，当我尝试使用UpdateView更新对象时，不会显示任何错误，表明它无法正常工作，而是将更改的数据传递到url来重新加载页面：

“ [[11 / Dec / 2018 11:49:20]”获取/ home / update / vacation / 421？csrfmiddlewaretoken = Op55u8r2GG2uyDjIvW2rstfedeU646ZkrJsmUOC6824rRO5W5NTT4koNwNCIBmof＆poste_travail = poste + test3

我试图覆盖form_invalid和fom_valid来了解正在发生的事情，但它不会打印任何内容

有人知道为什么这不起作用吗？

        vacation.save()

Answer 1

您没有为表单设置method。这意味着表单正在使用默认方法GET进行提交。

尝试将vacation_update.html更改为：

{% extends 'base.html' %}
{% block title %} {{ request.user }}{% endblock %}
{% block ligne-titre %}{{ client }}{% endblock %}
{% block sans-div %}
<div class="main container-fluid col-8">

<form class="form-group" method="post">
    {% csrf_token%}
    <table class="table table-sm table-bordered">

    {{ form.as_table }}
    <tr>
        <td colspan="2"><input class="align-self-center btn btn-secondary " type="submit" value="Nouveau"></td>
    </tr>
    </table>
</form>
</div>
{% endblock %}
