Class 在Django视图中将类指定给变量

我正在阅读这些代码块（在Django视图文件的函数中找到），其中类作业被分配给变量作业，如下所示（参考最后6行）。这些代码在网上找不到

我以前从未遇到过这种调用外部类的方法。这是Django中将类分配给变量的常用方法吗

谢谢

def ajax_save_job(request,session):
    c = {}
    user_model = session.get_property('user_model')
    userid = user_model.get_property('UserID')
    JobID = request.POST.get('JobID',False)
    collectAddress = request.POST.get('collectAddress',False)
    collectContactNumber = request.POST.get('collectContactNumber',False)
    collectContactName = request.POST.get('collectContactName',False)
    deliverAddress = request.POST.get('deliverAddress',False)
    deliverContactNumber = request.POST.get('deliverContactNumber',False)
    deliverContactName = request.POST.get('deliverContactName',False)
    collectCompanyName = request.POST.get('collectCompanyName',False)
    deliverCompanyName = request.POST.get('deliverCompanyName',False)
    price = request.POST.get('price',False)
    parcelWeight = request.POST.get('parcelWeight',False)
    parcelSize = request.POST.get('parcelSize',False)
    collectDate = request.POST.get('collectDate',False)
    collectTimeFrom = request.POST.get('collectTimeFrom',False)
    collectTimeEnd = request.POST.get('collectTimeEnd',False)
    deliverDate = request.POST.get('deliverDate',False)
    deliverTimeFrom = request.POST.get('deliverTimeFrom',False)
    deliverTimeEnd = request.POST.get('deliverTimeEnd',False)
    rearrangementStatus = request.POST.get('rearrangementStatus',False)
    rearrangementMaxLimit = request.POST.get('rearrangementMaxLimit',False)
    RearrangementExpiry = request.POST.get('RearrangementExpiry',False)
    parcelDescription = request.POST.get('parcelDescription',False)
    collectedon = request.POST.get('collectedon',False)
    deliveredon = request.POST.get('deliveredon',False)
    collectPostal = request.POST.get('collectPostal',False)
    deliverPostal = request.POST.get('deliverPostal',False)
    assignedTo = request.POST.get('assignedTo',False)
    status = request.POST.get('status',False)
    job = False
    output = {}
    try:
        job = Job.init(JobID,index="JobID",multiple=False)
        if (job.properties['status'].lower() == 'processing' or job.properties['status'].lower() == 'bidding') and assignedTo != job.properties['assignedTo'] :
            status ='Assigned'
    except:
        job = False

班级作业（基本）：

在我看来，这只是一个猜测，就像这里发生的事情是，你正在用给定的id创建一个Job实例，告诉它“multiple=False”，你的意思是，如果它已经存在，你想要的是现有的，而不是新的，类似于get或create标志。然后，你可以使用该工作的状态来更新你要做的任何事情的状态

显然，没有更多的事情要做，这只是一个暗中的刺杀

谢谢你的解释。我还加入了班级工作代码。

table = 'tbl_jobs'
index = 'JobID'

def __init__(self,**kwargs):
    Base.__init__(self)
    self.keys = ['JobID']
    self.required_property_list = ['postByUserID','price']
    self.unique_properties = []
    self.db_fields = ['paypalToken','JobID','postByUserID','jobName','parcelDescription','parcelSize','parcelWeight','declaredValue','collectDate','collectTimeFrom','collectTimeEnd','collectContactName','collectContactNumber','collectPostal','collectAddress','collectRegion','collectLatitude','collectLongitude','deliverDate','deliverTimeFrom','deliverTimeEnd','deliverContactName','deliverContactNumber','deliverPostal','deliverAddress','deliverRegion','deliverLatitude','deliverLongitude','biddingTime','biddingTimeEnd','price','postedOn','assignedTo','posted_by','PAID','jobType','status','paymentMethod','collectCompanyName','deliverCompanyName','collectSelfRefName','deliverSelfRefName','collectContactEmail','deliverContactEmail']

    if len(kwargs) == 0:
        return

    for key in kwargs:     
        self.properties[key] = kwargs[key] 

    missing_properties = self.required_properies()
    if len(missing_properties) > 0:
        raise UserModelPropertyMissingException('Required Property Missing',missing_properties)
