python - int() 参数必须是字符串、类似字节的对象或数字，而不是 'QueryDict'

Question

最近，当我单击“提交”和默认用户外键时，我尝试将数据保存到我的数据库中。但我遇到了这个错误，并试图通过查看网络来解决，但找不到任何类似的问题。

我的观点.py

from django.shortcuts import render,redirect
from .models import TimesheetDetails
from django.contrib.auth.decorators import login_required

# Create your views here.
@login_required(login_url="/login")
def create_timesheet_view(request):
    if request.method=="POST":
        print(request.POST)
        if ('dateToday' and 'dayToday' and 'startTime' and 'endTime' and
            'breakTime' and 'weekType' and 'attendance' and 'normalTime' and 'extraTime'
            and 'holidayTime' and 'workContent') in request.POST:
            #post.user = request.POST.get('user')
            post = TimesheetDetails()
            post.username = request.POST.get('username')
            post.date = request.POST.get('dateToday')
            post.day = request.POST.get('dayToday')
            post.startTime = request.POST.get('startTime')
            post.endTime = request.POST.get('endTime')
            post.breakTime = request.POST.get('breakTime')
            post.normalTime = request.POST.get('normalTime')
            post.overTime = request.POST.get('extraTime')
            post.holidayTime = request.POST.get('holidayTime')
            post.weekType = request.POST.get('weekType')
            post.attendance = request.POST.get('attendance')
            post.content = request.POST.get('workContent')
            post = TimesheetDetails(request.POST,request.FILES)
            print (request.POST)
            instance  = post.save()
            instance.user = request.user
            instance.save()
            return redirect('/list')        
    return render(request,'timesheet/create_timesheet.html')

def view_timesheet(request):
    context = {'timesheet_list': TimesheetDetails.obejcts.all()}
    return render(request,"timesheet/view_timesheet.html")

我的模型.py

from django.db import models
from django.contrib.auth.models import User

# Create your models here.
class TimesheetDetails(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE,related_name="timesheet",null="False")
    date = models.CharField(max_length = 10)
    day = models.CharField(max_length = 10)
    startTime = models.CharField(max_length =10)
    endTime = models.CharField(max_length =10)
    breakTime = models.CharField(max_length=3)
    normalTime = models.CharField(max_length=10)
    overTime = models.CharField(max_length = 10)
    holidayTime = models.CharField(max_length = 10)
    weekType = models.CharField( max_length = 10)
    attendance = models.CharField( max_length = 10)
    content = models.TextField( max_length = 300)

我的错误

任何帮助将不胜感激。上次尝试不使用外键，我能够保存数据。但我希望特定用户保存他的数据并仅查看他的数据。

Answer 1

您需要删除 post = TimesheetDetails(request.POST,request.FILES)线，自 TimesheetDetails是不是 Form 。话虽如此，最好 work with forms .

另一个问题是'foo' and 'bar' in request.POST只会检查是否 'bar'位于request.POST ，因为它只会评估 'foo' 的真实性，非空字符串有 True作为真理。

@login_required(login_url="/login")
def create_timesheet_view(request):
    if request.method=="POST":
        print(request.POST)
        if all(x in request.POST for x in ('dateToday', 'dayToday', 'startTime', 'endTime', 'breakTime', 'weekType', 'attendance', 'normalTime', 'extraTime', 'holidayTime', 'workContent')):
            post = TimesheetDetails.objects.create(
                user=request.user,
                date=request.POST.get('dateToday'),
                day=request.POST.get('dayToday'),
                startTime=request.POST.get('startTime'),
                endTime=request.POST.get('endTime'),
                breakTime=request.POST.get('breakTime'),
                normalTime=request.POST.get('normalTime'),
                overTime=request.POST.get('extraTime'),
                holidayTime=request.POST.get('holidayTime'),
                weekType=request.POST.get('weekType'),
                attendance=request.POST.get('attendance'),
                content=request.POST.get('workContent')
            )
            return redirect('/list')        
    return render(request,'timesheet/create_timesheet.html')

但在这里定义 ModelForm 肯定更好。 ，因为这可以删除大量样板代码。

此外，您可能最好使用 redirect(..) 中 View 的名称。调用，并且不是绝对路径。
