python-3.x - Django 'decimal.Decimal' 对象中的视图函数中的错误不可迭代
问题描述
我有三个模型

请提供一些帮助或提示为什么我在我的视图函数中收到此错误
def EmployeeRateView(request):
msg = ''
try:
fromDate = request.POST.get('fromdate')
except:
msg = "Pleas enter valid date"
if request.method == 'POST':
RateData = EmployeeRate.objects.filter(Site=request.user.SuperVisor.Site,DateFrom=fromDate)
return render(request,"employeerate.html",{"EmployeeRate":RateData,"msg":msg})
else:
print("get")
rate = Rate.objects.filter(Site=request.user.SuperVisor.Site)
EmpDetails = EmployeeRegistration.objects.filter(Site=request.user.SuperVisor.Site,Status="Working")
for employee in EmpDetails:
for get in rate:
print("date",get.fromDate)
if(employee.Site==get.Site and employee.Category==get.Category and employee.Department==get.Department):
try:
check = EmployeeRate.objects.get(EmpId=employee.EmpId,DateFrom=get.fromDate)
print("found",check.EmpId,check.Name,get.fromDate)
except:
print("not found",check.EmpId,check.Name,get.fromDate)
rate = get.Basic+get.Da
print(rate)
print("basic",get.Basic,"da",get.Da,"rate",rate)
EmployeeRate.objects.create(EmpId=employee.EmpId,
Name=employee.Name,
Site=employee.Site,
Basic=get.Basic,
Da=get.Da,Rate=rate,
Hra=get.Hra,
Ca=get.Ca,
SplAllow=get.SplAllow,
CanteenAllow=get.CanteenAllow,
DateFrom=get.fromDate)
context = {'EmployeeRate':EmployeeRate.objects.filter(Site=request.user.SuperVisor.Site).order_by('Name'),'msg':msg}
return render(request,"employeerate.html",context)
这是我的模板代码
{% if msg %}
<p class="alert alert-warning">{{msg}}</p>
{% endif %}
<div class="container" style=" padding: 0 !important; margin-top: 15px;background-color: #ffffff">
<div class="card">

</div>
<a href="{% url 'rate' %}" class="btn btn-warning" style="font-weight:900; color: whitesmoke;">Update Rate</a>
<form method="POST" action="{% url 'rate' %}"> {% csrf_token %}
<div class="row justify-content-center">
<div class="col-md-4" style="margin-top: 5px; margin-bottom: 5px;">

{% for ratedetails in EmployeeRate %}
<tr>

<td>{{ ratedetails.Basic }}</td>
<td>{{ ratedetails.Da }}</td>

{% endfor %}
</threed>

</div>

这是我的终端和浏览器中的错误基本上我正在尝试根据过滤器和条件在 EmployeRate 模型中保存或创建一些数据。但最后它给了我这种类型的错误。我无法理解为什么它会这样显示。
解决方案
最后我克服了这种情况并找到了我的解决方案。
其实问题就在这里
for employee in EmpDetails:
**for get in rate:** #looping in rate and initializing a variable by same name rate withing for loop of rate
print("date",get.fromDate)
if(employee.Site==get.Site and employee.Category==get.Category and employee.Department==get.Department):
try:
check = EmployeeRate.objects.get(EmpId=employee.EmpId,DateFrom=get.fromDate)
print("found",check.EmpId,check.Name,get.fromDate)
except:
print("not found",check.EmpId,check.Name,get.fromDate)
**rate = get.Basic+get.Da** # this was the actual error
print(rate)
print("basic",get.Basic,"da",get.Da,"rate",rate)
