Web2py 条件可读字段

Question

web2py 的完整新手...我想让表单底部的复选框仅在用户是管理员用户时有条件地显示。如果非管理员用户看不到它，我如何解决字段名称以便我可以更改？

我正在使用 for 循环来引用一个循环变量，不确定我是否需要它...

## create all tables needed by Technical Request Form
db.define_table('technical_request',
Field('uuid', 'string', default=uuid.uuid4(), readable=False, writable=False),
Field('firstname', requires=IS_NOT_EMPTY(error_message='All Fields are Required!'), label="First Name"),
Field('lastname', requires=IS_NOT_EMPTY(error_message='All Fields are Required!'), label="Last Name"),
Field('phone', requires=IS_NOT_EMPTY(error_message='All Fields are Required!'), label="Phone Number"),
Field('email', requires=IS_NOT_EMPTY(error_message='All Fields are Required!'), label="Email"),    
Field('issue_name', requires=IS_NOT_EMPTY(error_message='All Fields are Required!'),label="Subject"),
Field('about_issue', 'text', requires=IS_NOT_EMPTY(error_message='All Fields are Required!'), label="Description of issue "),
Field('issue', 'upload', label="Attach Files "),
Field('request_processed', 'boolean', default=False, readable = False),
auth.signature)

for field in db.technical_request:
  if field.name == 'request_processed' and auth.has_group_membership("systemadmin"):
    field.readable = True

这是我要隐藏的复选框....

有没有办法可以有条件地添加字段？

无需循环——您可以直接通过其名称访问该字段：

db.technical_request.request_processed.readable = auth.has_group_membership("systemadmin")

或者只是在定义字段时这样做：

Field('request_processed', 'boolean', default=False,
      readable=auth.has_group_membership("systemadmin"))
