创建用户认证蓝本在abp.py中
在工厂文件中导入 LoginManager
在LoginManager中有一属性为session_protection，可设置为None,basic,strong选择basic，否则关闭浏览器后再打开再按home会登出。
改变表单长度：<div class="col-mg-3">
{{wtf.quick_form()}}
</div>
如果表单类实现了以validate_开头且后面跟这表单字段名的方法，这个方法会和常规的验证函数一起被调用。
源码如下 ：
def validate(self):
"""
Validates the form by calling `validate` on each field, passing any
extra `Form.validate_<fieldname>` validators to the field validator.
"""
extra = {}
for name in self._fields:
inline = getattr(self.__class__, 'validate_%s' % name, None)
if inline is not None:
extra[name] = [inline]
return super(Form, self).validate(extra)
def validate(self, extra_validators=None):
"""
Validates the form by calling `validate` on each field.
:param extra_validators:
If provided, is a dict mapping field names to a sequence of
callables which will be passed as extra validators to the field's
`validate` method.
Returns `True` if no errors occur.
"""
self._errors = None
success = True
for name, field in iteritems(self._fields):
if extra_validators is not None and name in extra_validators:
extra = extra_validators[name]
else:
extra = tuple()
if not field.validate(self, extra):
success = False
return success
