在Django admin中将所有数据从一个表单复制到另一个表单

I'm having trouble making the data from a form be sent to a new form in my application. I want to do the following: After the user clicks a button within a record, that record data be copied to another empty form.

我无法将表单中的数据发送到我的应用程序中的新表单。我想执行以下操作:在用户单击记录中的按钮后,该记录数据将被复制到另一个空表单。

No need to store these values permanently or for a long time. Only in the transition from one form to another with populated fields blank form.

无需永久或长期存储这些值。仅在从一个表单到另一个表单的过渡中,填充字段为空白表单。

Basically a Ctrl + C - Ctrl + V form, but without saving the record after copying ...

基本上是一个Ctrl + C - Ctrl + V形式,但复制后没有保存记录...

I've done something like working with URL parameters, but would like something cleaner. I need to copy values including the inlines.

我做过像URL参数一样的工作,但想要更清洁。我需要复制包括内联的值。

I thought of storing the data in the session, and then retrieve them at the target form. However, I do not know if it's the best way to implement it. If so, how can I work with the session in Django?

我想过将数据存储在会话中,然后在目标表单中检索它们。但是,我不知道这是否是实施它的最佳方式。如果是这样,我如何在Django中使用会话?

This is the code I have so far in my admin.py file:

这是我目前在admin.py文件中的代码:

def response_change(self, request, obj):
    # name of the custom button
    if '_copy_and_paste' in request.POST:
        # getting the data and storing the session
        request.session['field_1'] = obj.field_1
        request.session['field_2'] = obj.field_2

        return super(MyClassAdmin, self).response_change(request, obj)

I'm using the Django admin (version 1.8).

我正在使用Django管理员(版本1.8)。

There is no need to store this information in session, you can pass the request object back to your template page.

无需在会话中存储此信息,您可以将请求对象传递回模板页面。

In your settings.py file, make sure context_processors.request is inside the context_processors:

在settings.py文件中,确保context_processors.request位于context_processors中:

TEMPLATES = [
    {
        ...
        'OPTIONS': {
            'context_processors': [
                ...,
                'django.template.context_processors.request',  #<- make sure this line is here
                ...,
            ],
        },
    },
]

Then, in your views.py

然后,在views.py中

from django.shortcuts import render

def response_change(request):
    if '_copy_and_paste' in request.POST:
        return render(request, 'your_template.html')

In your template, to access the data stored in request:

在您的模板中,访问存储在请求中的数据:

<input type="text" name="field1" value="{% if request.POST.field1 %}{{ request.POST.field1}}{% endif %}">
