import_data() 缺少 1 个必需的位置参数：'dataset' -

Question

当我想使用 django import export user model ressource 从数据集中导入数据时遇到问题：

错误：

import_data() missing 1 required positional argument: 'dataset'

Request Method:     GET

Request URL:    http://localhost:8000/home/
Django Version:     1.11.6
Exception Type:     TypeError
Exception Value:    

import_data() missing 1 required positional argument: 'dataset'

Exception Location:     /code/data_integration/tasks.py in MvmtjsHms, line 197
Python Executable:  /usr/local/bin/python3
Python Version:     3.4.2

我的资源：

class MasterDossierResource(resources.ModelResource):
            class Meta:
                model = MasterDossier
                skip_unchanged = True
                report_skipped = False
                import_id_fields = ('indice',)
                exclude = ('id',)
                fields = ('indice', 'plt', 'ref_dossier',)

我的模型：

class MasterDossier(models.Model):
    indice = models.CharField(max_length=40, primary_key=True)
    plt = models.CharField(max_length=3)
    ref_dossier = models.CharField(max_length=20)

我的代码：

我根据条件使用现有文件来实现我的数据集，我想使用我的模型的资源来测试数据集集成

 def Mvmtjs(self,file, espace):

        import csv

        csvfile = open(file, 'r')
        reader = csv.reader(csvfile,delimiter=';')

        dataset = tablib.Dataset(headers=['indice', 'plt', 'ref_dossier_ath'])
       ]


        with open('tmp/edi/in/working/write_file.csv', "w+", encoding='mac_roman', newline='') as csv_file1:  


            next(reader)  # Skip header row.
            next(reader)  # Skip header row.

            for row in reader:


                if row[2] != "":

                    if espace == '1' or '2':

                    dataset.append( (
                               row[2],
                               row[0], 
                               row[2], 
                                  ))

        result = MasterDossierResource.import_data(dataset, dry_run=True, raise_errors=True)

提前致谢

我的资源出错了...我忘了初始化我的资源：

dossier_ressource = MasterdossierRessource()
result = dossier_ressource.import_data(dataset, dry_run=True, raise_errors=True)
