django表单从cookie获取值 [英] django forms get value from cookies

问题描述

如何使django表单从Cookie获取值？我保存用户previuos输入到cookies，如果用户再次打开表单我想显示的值。

How to make django forms get value from cookies? I save user previuos input to cookies and if user opens form again I want to show that values.

现在我手动形式如下：

<select name="transmission_type" class="selectpicker">
    <option value="" selected>Select value</option>
    {% for transmission in transmissions %}
    {% if transmission == request.COOKIES.transmission %}
    <option value="{{ transmission.id }}" selected>{{transmission }}</option>
    {% else %}
    <option value="{{ transmission.id }}">{{transmission }}</option>
    {% endif %}
    {% endfor %}
</select>

我如何在django表单中执行此操作？

推荐答案

我自己解决了这个问题。您只需要在视图中为您的表单使用django表单初始属性。

I solved this by myself. You just need to use django forms initial attribute for your form in views.

解决方案示例：

if 'something' in request.COOKIES:
    something = request.COOKIES['something']
else:
    something = ''


form = SomethingForm(initial={'something': something })
