Question

我真的需要一些代码的帮助。我不希望你为我写这篇文章，因为这是一个学校项目，但我真的迷失了，需要帮助。

我写的代码是某种生产系统它实际上不需要在任何地方发送任务，因为这只是一个想象的场景。

代码必须由三个文件组成：data.py，model.py和gui.py.

Gui可以访问其他两个文件
数据只能访问模型
模型无法访问其他两个中的任何一个。

我的老师写了一些我继续写的代码。有些文字是丹麦语，但大多数评论都是英文的。代码如下。

data.py

from model import *

class Data(object):

def __init__(self):
    self.units = []
    self.finished_tasks = []

def __str__(self):
    result = "These tasks have been finished: "
    for i in self.finished_tasks:
        result += str(i)
    return result

def task_done(self, unit):
    done_task = unit.task_done()
    if done_task != None:
        #TODO: add to list of finished tasks
        pass

def add_task(self, name, amount, unit):
    s = Springroll_task(name, amount)
    unit.add_to_queue(s)

def read_from_database(self):#doesn't actually read from db..
    self.units.append(Production_unit("maskine1"))
    self.units.append(Production_unit("maskine2"))

    self.add_task("Miniruller", 100, self.units[0])
    self.add_task("Maxiruller", 200, self.units[0])
    self.add_task("HowIRoll", 3000, self.units[0])
    self.add_task("RulleMarie", 40, self.units[1])
    self.add_task("Rullesten", 500, self.units[1])
    self.add_task("Toiletpapirsruller", 6000, self.units[1])

model.py

    class Springroll_task(object):

    def __init__(self, name, amount):
        self.name = name
        self.amount = amount

    def __str__(self):
        return self.name + " " + str(self.amount)


class Production_unit(object):

    def __init__(self, amount={}, name={},):
        #name of the production unit
        self.name = name
        self.amount = amount
        #the current task
        self.current_task = None
        #the tasks in the queue
        self.springroll_queue = []
        #the size of the queue
        self.queue_size = 0

    def __str__(self):
        #TODO
        return self.name + " " + str(self.amount)

    def add_to_queue(self, task={}):
        if self.current_task == None:
            self.current_task = task
        else:
            self.springroll_queue.append(task)
            self.queue_size += 1
            #remember to update queue_size
            pass

    def task_done(self):
        #TODO: remember the old current task.
        #Set the current task to be the first in the queue (and remove from queue)
        # - if there is a task in the queue.
        #return the old current task.
        #remember to update queue_size
        self.queue_size -= 1
        pass

gui.py

from tkinter import *
from model import *
from data import Data

class Application(Frame):
    def __init__(self, master, unit):
        self.mod = Production_unit()
        super(Application, self).__init__(master)  
        self.grid()
        self.unit = unit
        self.create_widgets()



    def create_widgets(self):
        self.unit_name_lbl = Label(self, text = self.unit.name)
        self.unit_name_lbl.grid(row = 0, column = 0, columnspan = 2, sticky = W)

        self.cur_prod_lbl = Label(self, text = "produktion nu: ")
        self.cur_prod_lbl.grid(row = 1, column = 0, columnspan = 2, sticky = W)

        self.prod_lbl = Label(self, text = "produkt")
        self.prod_lbl.grid(row = 2, column = 0, sticky = W)

        self.amount_lbl = Label(self, text = "antal")

        #Label for production now
        self.amount1_lbl = Label(self, text = "             ", bg ="red")
        self.amount1_lbl.grid(row = 3, column = 0, sticky = W)

        self.amount2_lbl = Label(self, text = "      ", bg ="red")
        self.amount2_lbl.grid(row = 3, column = 1, sticky = W)
        #Button for task finished
        self.finished_but = Button(self, text = "Opgave afsluttet", bg ="pink", command=self.mod.task_done)
        self.finished_but.grid(row = 3, column = 2, sticky = W)

        #Label for queue
        self.queue_lbl = Label(self, text = "Kø")
        self.queue_lbl.grid(row = 4, column = 0, sticky = W)
        #Label for production queue
        for i in range(0,3):
            self.name_lbl =Label(self, text = self.mod.springroll_queue, bg="red", width= 6)
            self.name_lbl.grid(row = 5+i, sticky = W)

        for j in range(0,3):
            self.qt_lbl =Label(self, text = self.mod.springroll_queue, bg="red", width= 4)
            self.qt_lbl.grid(row = 5+j, column = 1)

        self.new_lbl = Label(self, text = "Ny")
        self.new_lbl.grid(row = 10, column = 0, sticky = W)
        #Entry for entries
        self.eq1_ent = Entry(self, text = "", width=6)
        self.entry_name = self.eq1_ent.get()
        self.eq1_ent.grid(row = 11, sticky = W)

        self.ea1_ent = Entry(self, text = "", width=4)
        self.ea1_ent.grid(row = 11, column = 1, sticky = W)
        #Button for add to queue
        self.add_but = Button(self, text = "Tilføj til kø", bg ="pink", command=self.mod.add_to_queue(self.ea1_ent.get()))
        self.add_but.grid(row = 11, column = 2, sticky = W)





    def done(self):
        d.task_done(self.unit)
        self.redraw()

    def add(self):
        n = "Nyt navn" #read from gui
        a = "Nyt antal" #read from gui
        d.add_task(n, a, unit)
        self.redraw()


    def redraw(self):
        #TODO
        pass

# main
root = Tk()
root.title("Daloon")
root.geometry("300x300")

d = Data()

d.read_from_database()

p = d.units[0]

app = Application(root, p)

root.mainloop()

所以它目前看起来像这样：

我需要做的是在底部的两个条目小部件中输入一个输入并将它们放在上面的4个标签小部件之一中，从顶部开始然后在队列中，这应该发生在我按下add_but按钮，目前似乎已经消失了。
之后，当按下“Opgave afsluttet”按钮时，我需要存储在数据文件中的任务。

我真的希望有人能够帮助我！

我用一些建议编辑了它，我现在正在调用正确的self.eq1_ent.get（）。我不再有任何错误，现在我真的不知道如何让它做我想要的。编辑2：我正在慢慢得到一些东西，所以我在model.py和gui.py中进行了更改...... 它现在看起来像这样：

Answer 1

self.eq1未定义。你有self.q1_lbl和self.eq1_ent 要访问该标签，请使用self.q1_lbl。

为了能够在标签上设置文字，请按以下方式创建：

self.var = StringVar()
self.unit_name_lbl = Label(self, textvariable=self.var)

例如，从redraw()开始，您可以将'text'设置为self.unit_name_lbl，如下所示：self.var.set('text')。

检查您是否错过self

d.add_task(n, a, unit)

执行command=mod.add_to_queue(self.ea1_ent.get())时，将直接调用mod.add_to_queue函数，如果要在用户按下按钮时将参数传递给此函数，则可以使用lambda：
```
command=lambda: mod.add_to_queue(self.ea1_ent.get)
```

Python Tkinter。如何通过标签中的按钮存储条目
