Question

我正在修改查询数据库并返回过去7天内信息的现有应用。我已经合并了一个日历应用程序，因此可以选择自己的日期进行查询。

日历工作得很好

import tkinter as Tkinter
import tkinter.font as tkFont
import tkinter.ttk as ttk
import ttkcalendar
import pandas as pd
import numpy as np
import tkSimpleDialog  
from datetime import date

class CalendarDialog(tkSimpleDialog.Dialog):
    """Dialog box that displays a calendar and returns the selected date"""

    def body(self, master):
        self.calendar = ttkcalendar.Calendar(master)
        self.calendar.pack()

    def apply(self):
        self.result1 = self.calendar.selection
        self.result2 = self.calendar.selection

class CalendarFrame(Tkinter.LabelFrame):

    def __init__(self, parent):
        Tkinter.LabelFrame.__init__(self, parent, text="Choose Dates")

    def getbegindate():
        cd = CalendarDialog(self)
        self.result1 = cd.result1
        self.Begin_date.set(self.result1.strftime("%m/%d/%Y")) 

    def gettodate():
        cd = CalendarDialog(self)
        self.result2 = cd.result2
        self.To_date.set(self.result2.strftime("%m/%d/%Y"))

    self.Begin_date = Tkinter.StringVar()
    self.To_date = Tkinter.StringVar()

    def get_date():
        end = self.result2.strftime("%m/%d/%Y")
        start = self.result1.strftime("%m/%d/%Y")
        end1 = self.result2.strptime(end, "%m/%d/%Y").date()
        start1 = self.result1.strptime(start, "%m/%d/%Y").date() 
        delta = (end1 - start1).days
        daterange = [pd.date_range(start, end)]
        for single_date in daterange:
            x = single_date.strftime("%m/%d/%Y")
        rundate = x
        print(rundate) 

    Tkinter.Button(self, text="From date", command=getbegindate).grid(column=0, row=0)
    Tkinter.Entry(self, textvariable=self.Begin_date).grid(column=1, row=0)
    Tkinter.Entry(self, textvariable=self.To_date).grid(column=1, row=1)
    Tkinter.Button(self, text="To date", command=gettodate).grid(column=0, row=1)
    Tkinter.Button(self, text="SUBMIT", command=get_date).grid(column=0, columnspan=3)

def main():
    root = Tkinter.Tk()
    root.wm_title("Pick1")
    root.geometry("250x150+100+100")
    CalendarFrame(root).grid()
    root.mainloop()

if __name__ == "__main__":
    main()

在返回7天后，每周一次的工作仍然可以正常工作。

当选择日期范围时，它会返回＆＃34;无＆＃34;并返回一个未填充的屏幕。如何从日历中获取日期（Pick1.py）以填充我的查询

app_window = tk.Tk()
app_window.withdraw()

def rundate():
    result = tkinter.messagebox.askyesno(title="Rundate", message="back 7 days?")
    # result = tkinter.messagebox.askyesno()
    if result == True:
        rundate = date.today() - timedelta(7)
        return rundate
    else:
        os.system("pick1.py")
        def get_date():
                end = self.result2.strftime("%m/%d/%Y")
                start = self.result1.strftime("%m/%d/%Y")
                daterange = [pd.date_range(start, end)]

                rundate = x
                return rundate

rundate = rundate()
print(rundate)

# Query permits made effective since rundate
query = '''select `NPDES_ID`, `EffectiveDate`, `FacilityName`, `StateFacilityID`, `City`, `CountyName`

count=0
# for each row in result of query

    except:
        d=""
    # create a display string with the appropriate information permit # - date -  facility name - city, county
    for i in range(len(row)):
            if not row[i]:
            row[i] = ""

    permitstring=row[0]+" | "+d+"\t | "+row[2]+"\t | "+row[4]+", "+row[5]+" County"
    IDS.append(row[0])
    tempid=row[0]
    # add the index to the appropriate permit type array, used to display seperately
    if tempid[0:3]=="MTB":
        MTB.append(count)
    if tempid[0:3]=="MTG":
        MTG.append(count)
    if tempid[0:4]=="MTR0":
        MTR.append(count)
    if tempid[0:3]=="MT0" or tempid[0:3]=="MT4" or tempid[0:3]=="MTX":
        MT0.append(count)
    if tempid[0:4]=="MTR1":
        SWC.append(count)
    FacCodes.append(row[3])
    PermStrings.append(permitstring)
    count+=1

这是一个相当大的应用程序，所以我希望我包含重要的部分，看看我失败的地方

我修复了你的代码，它现在正在运行，但我尽可能少地改变它才能让它运行起来。大多数问题都是由错误使用类和面向对象编程引起的。所以如果我为你重写整个程序，我认为它不会有任何帮助，但我认为你应该自己学习python中的OOP编程。您可以在这些页面上找到一些基础知识（learnpython，tutorialspoint，introtopython）或只需输入谷歌，您就会找到很多页面，视频，课程等。

这是固定代码：

import pick1  ## This import line you need so you can use code from that file

app_window = tk.Tk()
#app_window.withdraw()              ## we use these three lines below because we only want to hide
app_window.geometry("1x1+0+0")      ##  tkinter window temporarily and withdraw() method causes
app_window.overrideredirect(True)   ##  the window to beforgotten about by the window manager
app_window.transient()             ## more details on https://wiki.tcl.tk/3175


def rundate():
    result = tkinter.messagebox.askyesno(title="Rundate", message="back 7 days?")
    #result = messagebox.askyesno(title="Rundate", message="back 7 days?")

    # result = tkinter.messagebox.askyesno()
    if result == True:
        rundate = date.today() - timedelta(7)
        return rundate
    else:
        #os.system("pick1.py")
        #root = tkinter.Tk()
        app_window.wm_title("Pick1")
        app_window.geometry("250x150+100+100")
        app_window.overrideredirect(False)
        #app_window.mainloop()
        cm = pick1.CalendarFrame(app_window)
        cm.grid()
        ## here we wait until user has selected data range and
        ## and rundate has been calculated
        app_window.wait_variable(cm.wait_for_result)
        return cm.rundate

## we don't need this function because there is already same function in file pick1.py 
##        def get_date():
##            end = self.result2.strftime("%m/%d/%Y")
##            start = self.result1.strftime("%m/%d/%Y")
##            daterange = [pd.date_range(start, end)]
##            for single_date in daterange:
##                x = single_date.strftime("%m/%d/%Y")
##            rundate = x
##            return rundate



rundate = rundate()
print(rundate)

# Query permits made effective since rundate
query = '''select `NPDES_ID`, `EffectiveDate`, `FacilityName`, `StateFacilityID`, `City`, `CountyName`
        from Permits 
        where `EffectiveDate` >= ?
        order by `NPDES_ID`'''

IDS=[]
FacCodes=[]
PermStrings=[]
PayStrings=[]
OwnerStrings=[]
MTB=[]
MTG=[]
MTR=[]
SWC=[]
MT0=[]
count=0
# for each row in result of query
for row in cur.execute(query, (rundate, )):
    try:
        d= row[1].strftime('%m/%d/%Y')
    except:
        d=""
    # create a display string with the appropriate information permit # - date -  facility name - city, county
    for i in range(len(row)):
        if not row[i]:
            row[i] = ""

    permitstring=row[0]+" | "+d+"\t | "+row[2]+"\t | "+row[4]+", "+row[5]+" County"
    IDS.append(row[0])
    tempid=row[0]

    if tempid[0:3]=="MTB":

和pick1.py的代码：

        self.result2 = cd.result2
        self.To_date.set(self.result2.strftime("%m/%d/%Y"))

    #self.Begin_date = Tkinter.StringVar()

        daterange = [pd.date_range(start, end)]
        for single_date in daterange:
            x = single_date.strftime("%m/%d/%Y")
        self.rundate = x
        self.wait_for_result.set(1)     # now we have result so we can set variable wait_for_result to 1
        print(self.rundate)
        self.parent.destroy()        # I added this line so tkinter window disappears once when user clicks SUBMIT button

    #Tkinter.Button(self, text="SUBMIT", command=get_date).grid(column=0, columnspan=3)

Answer 2

所以我使用上面的答案让日历工作 - 谢谢@ands

result = tkinter.messagebox.askyesno(title="Rundate", message="back 7 days?")
if result == True:
    start = date.today()
    end = date.today() - timedelta(7)
    daterange = [pd.date_range(start, end)]
    for single_date in daterange:
        x = single_date.strftime("%m/%d/%Y")
    rundate = x
    print(rundate)
    return rundate
else:
    app_window.wm_title("Pick1")
    app_window.geometry("250x150+100+100")
    app_window.overrideredirect(False)
    #app_window.mainloop()
    cm = pick1.CalendarFrame(app_window)
    cm.grid()
    app_window.wait_variable(cm.wait_for_result)
    return cm.rundate

rundate = rundate()
print(rundate)

并将weeklyrpt代码更改为：

# Query permits made effective since rundate
vars = ','.join(['?'] * len(rundate, ))

query = ('''select `NPDES_ID`, `EffectiveDate`, `FacilityName`, `StateFacilityID`, `City`, `CountyName`
        from Permits 
        where `EffectiveDate` IN (%s) 
        order by `NPDES_ID`''' % vars)

IDS=[]
FacCodes=[]
PermStrings=[]
PayStrings=[]
OwnerStrings=[]
MTB=[]
MTG=[]
MTR=[]
count=0
# for each row in result of query
for row in cur.execute(query, (*rundate, )):

再次感谢您的帮助!!
