从 django 表单获取会话值
Posted
技术标签:
【中文标题】从 django 表单获取会话值【英文标题】：Get session value from django form 【发布时间】：2022-01-22 09:48:12 【问题描述】：我有两种形式，一种是主要的，另一种在模式窗口中打开。 我需要我的第二个表单来获取公司会话值 (AIGN_EMP_ID)，但是，当我从 Context 调用我的表单时，我不知道如何发送此值。
第一种形式.py

request.session.AIGN_EMP_ID 是我想要获取的值，重点是获取从我的第二个表单中获取会话的值。

【讨论】：
您的答案可以通过额外的支持信息得到改进。请edit 添加更多详细信息，例如引用或文档，以便其他人可以确认您的答案是正确的。你可以找到更多关于如何写好答案的信息in the help center。【参考方案2】：在get_context 中，我可以发送带有值会话MayoresPrintForm(data=self.request.session) 的变量数据
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['page_title'] = 'Mayores'
context['url_list'] = self.success_url
context['MayoresPrintForm'] = MayoresPrintForm(data=self.request.session)
ret = []
ret.append(get_MayoresDetForm(kwargs).to_JSON())
context['grids_detalles'] = ret
return context
但我必须更改 Post 方法才能从那里检索表单值，如下所示：request.POST['act_cuenta_ini']
