model表
### 文件model class FileProperty(models.Model): filename = models.CharField(max_length=250, verbose_name='文件名称') productline = models.ForeignKey(ProductLine, verbose_name='产品线' ,null=True ,on_delete=models.SET_NULL) upload_time = models.DateTimeField(auto_now_add=True, verbose_name='上传时间') describe = models.CharField(max_length=1000, verbose_name='备注') ##产品线 class ProductLine(models.Model): name = models.CharField(verbose_name='产品线名称', max_length=250, unique=True)
需要向 FileProperty 表中插入一条数据,views.py 如下:
productline = request.POST.get('productline').strip() file_list = { 'filename': file.name, 'productline': productline 'describe': request.POST.get('describe', ''), } FileProperty.objects.create(**file_list)
当执行时报错如下:
FileProperty 字段 productline 为 ForeignKey(一对多) 解决方法:
productline_object = ProductLine.objects.get(name=productline) FileProperty.objects.create(**file_list, productline=productline_object)
FileProperty 字段 productline 为 ManyToManyField(多对多)时的解决方法:
productline_object = ProductLine.objects.get(name=productline) fileadd = FileProperty.objects.create(**file_list) fileadd.productline.add(productline_object)
