Python金字塔-使用会话将表单数据传递到另一个页面

我正在使用Python金字塔和Jinja2模板。我想将表单数据保存到会话中,并在另一个HTML页面中检索它。我应该如何更改以传递数据?我只知道如何存储我在视图中输入的数据。像这样进入会话 request.session['postal'] = 01934 但这不是我在交付中输入的数据。如果我用 print (session['postal']) ,这将仅显示在我的命令提示符中,而不会显示在HTML页面中。有人能帮我吗?我是这方面的新手。

在我的视图中添加/更改什么。py?

<form class="form-horizontal" method="POST">   
<div class="form-group">
    <label class="control-label col-md-2" for="postal">Postal Code:</label>
        <input type="text" class="form-control" id="postal" placeholder="Enter Postal Code" name="postal" />
</div>
<div class="form-group">
    <label class="control-label col-md-2" for="address">Detailed Address:</label>
        <textarea class="form-control" rows="3" id="address" placeholder="Enter Address" name="address"></textarea>
</div>
<div class="form-group">
    <label class="control-label col-md-2" for="unit">Unit No #:</label>
        <input type="text" class="form-control" id="unit" placeholder="Enter Unit No" name="unit" />
</div>
<button type="submit" class="btn btn-default" name="submit">Submit</button>
</form>

意见。py公司

@view_config(route_name='deliveryLink', renderer='templates/deliveryLink.jinja2')
def deliveryLink(request):
    print("YAY for gift delivery via Link")

if 'submit_deliverylink' in request.POST:
    print("request.POST: ", request.POST)

    myform = request.POST

    for m in myform:
        print("key: ", m, " value: ", myform[m])

    session = request.session

    session['postal'] = ?
    session['address'] = ?
    session['unit'] = ?

    data = "??"

    data_array = data.split(",")
    session['data'] = data_array

    session['delivery'] = str(data_array)

    print (session['delivery'])

    return HTTPFound(location='http://localhost:5555/confirmation')
return {}

@view_config(route_name='confirmation', renderer='templates/confirmation.jinja2')
def confirmation(request):
    print("YAY for confirmation")

        for a in request.POST:
            request.session[a] = request.POST[a]

    return {}

我希望之前输入的数据显示在这个确认页面上:确认。金贾2
