mongodb - 使用 Mongo 4 在 Web2py SQLFORM 上 PyDAL 引发错误

问题描述

Ubuntu 18 - Python 3.6.9 - Mongo 4

使用 Web2py 给出的 SQLFORM 我在 PyDAL 中遇到错误：

AttributeError：“表”对象没有属性“_notnulls”

我正在使用我的 auth.user 表来制作表单，并且它正在与我的应用程序的其余部分一起使用，除非将它与 SQLFORM 一起使用并尝试处理（）。

这是我抛出错误的代码，该代码是表单的标准 web2py 实践：

def my_form_processing(form):
        pass

db.auth_user.modified_by.writable = False
db.auth_user.created_by.writable = False
form = SQLFORM(db.auth_user)

if form.process(onvalidation=my_form_processing).accepted:
    session.flash = 'Record inserted'
    redirect(URL())
elif form.errors:
    response.flash = 'Form has errors'
else:
    session.flash = 'Please fill the form'

    return dict(form=form)

这是回溯：
