Python 在web2py中按日期生成特定数据

我被我的申请卡住了。 我想根据我想选择的日期从数据库中生成特殊数据

以下是我的模型：

以下是我的模块：

# coding: utf8
from gluon import *

# represent
represent_integer = lambda value, field: \
    SPAN('%s' % (format(value, ",d").replace(",", ".") ), 
         _class = 'text-success') if value > 0 else SPAN(0, _class = 'text-danger')
represent_url = lambda value, field: A('View', _target="_blank", _href="%s" % value) if value else ''

# requires
requires_date = lambda: \
    IS_DATE(format = current.T('%Y-%m-%d'), error_message = current.T('Enter date as yyyy-mm-dd') )

requires_set_not_empty = lambda list_value: IS_IN_SET(list_value, zero = current.T('Choose One') )

# widget
widget_string = lambda field, value: \
    SQLFORM.widgets.string.widget(field, value, 
                                  _class = "form-control string", 
                                  _placeholder = current.T('Should be filled') )

我想创建一个如下所示的控制器：

选择日期

开始日期：_________

结束日期：__________

提交（按钮）

所以在我按下提交按钮之后，我想要一个表来查看日期开始和日期结束之间的数据库。帮我一把，谢谢

------U p D A T D------

我在控制器中使用此代码

 def non_register(): 
    form = SQLFORM.factory(
    Field("start_date", type="date"),
    Field("end_date", type="date"))
    if form.process().accepted:
        q = ((db.lion.date_of_response >= form.vars.start_date) &
             (db.lion.date_of_response <= form.vars.end_date))
    rows = db(q).select()
    return dict(form=form,rows=rows)

def non_寄存器（）：
form=SQLFORM.factory(
字段（“开始日期”，type=“日期”），
字段（“结束日期”，type=“日期”））
如果接受form.process（）：
q=（（db.lion.date\u of\u response>=form.vars.start\u date）&
（db.lion.date_of_response可以用来创建所需的表单

form = SQLFORM.factory(
    Field("start_date", type="date"),
    Field("end_date", type="date"))

这将生成很好的日期选择器，
form.vars.start\u date
和
form.vars.end\u date
将是可以直接包含在DAL查询中的
datetime.date
实例

q = ((db.yourtable.date >= form.vars.start_date) &
     (db.yourtable.date <= form.vars.end_date))
rows = db(q).select()

q=（（db.yourtable.date>=form.vars.start\u date）&
（db.yourtable.date您的模型看起来像一个或另一个字段，而应该是一个引用。因此，我必须定义另一个表以在我的表单中模拟结果？@Alexaxel您将查询放在错误的位置。它应该像
db（查询）。选择（…）
，如我的示例所示。它显示了另一个错误，你能检查我更新的问题吗？我写错了吗？@Alexaxel请按照我的示例。你正在调用
db（）
，没有查询，它应该是
db（q）。选择（）
其中
q
正是我在示例中所说的。已经完成了您的代码，先生，谢谢您。但是如果我实现了您的代码，我会遇到这样的错误：“Field”对象没有属性“date”，我会写这个（db.lion.date\u of_response.date>=form.vars.start\u date）响应字段的.db.lion.date\u包含类似于2017-02-28的数据，因此错误来自何处？感谢您跟踪“.date”是错误的，它应该是：
db.lion.date\u\u响应>=form.vars.start\u date
。
q = ((db.yourtable.date >= form.vars.start_date) &
     (db.yourtable.date <= form.vars.end_date))
rows = db(q).select()
