我真的需要一些代码的帮助.我不希望你为我写这篇文章,因为它是一个学校项目,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.

代码必须包含三个文件：data.py,model.py和gui.py.

> Gui可以访问另外两个文件
>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

        super(Application, self).__init__(master)  
        self.grid()
        self.unit = unit

        self.amount2_lbl = Label(self, text = "      ", bg ="red")

    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个标签小部件中的一个中,从顶部开始然后在队列中,这应该在我按下按钮时发生add_but,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！

我编辑了一些建议,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：

最佳答案 self.eq1未定义.你有self.q1_lbl和self.eq1_ent.

要访问标签,请使用self.q1_lbl.

为了能够将文本设置为标签,请按以下方式创建：

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

例如,从redraw()可以将’text’设置为self.unit_name_lbl,如下所示：self.var.set(‘text’).

>检查你是否在d.add_task(n,a,unit)中错过了自己
>当你执行command = mod.add_to_queue(self.ea1_ent.get())时,将直接调用mod.add_to_queue函数,如果你想在用户按下按钮时将参数传递给该函数,你可以使用lambda：

command=lambda: mod.add_to_queue(self.ea1_ent.get)
