Turbogears2会话管理

Question

理论上，我做了我应该做的事情，以便在会话变量中存储一些数据，但我的控制器无法访问它们。代码如下：

    @expose('')
    @require(predicates.not_anonymous())
    def savecustomer(self, customer=None, **kw):
    if customer is None:
        flash(_('Select a customer!'), 'error')
        redirect('/')
    customer = DBSession.query(Customer).filter_by(customer_id=customer).first()
    session.delete()
    session['customer'] = True
    session['customer_id'] = customer.customer_id
    session['customer_name'] = customer.customer_name
    ...
    session.save()

下面是我的视图代码：

  {% if request.identity %}
      {% if session['customer'] %}
        <div class="customer"><i>{{ session['customer_name'] }}
              {% if session['customer_type'] %} {{ session['customer_type'] }} {% endif %}
              </i></div>
      {% else %}
        <div class="nocustomer">No customer selected</div>
      {% endif %}
  {% endif %}

下面是我的“调试”：

for i in session.iterkeys():
    print i
for i in session.itervalues():
    print i
customer
customer_id
customer_name
True

如果我在另一个控制器中运行相同的代码，它会得到如下结果：

_id

我做错了什么？(这曾经有效，直到我“修复”了其他东西:)

我解决了这个错误，删除了

session.delete()
