我可以在Django中以這種方式保存模型嗎？

Question

first_obj = MyFirstModel() 
second_obj = ImageModel() 

first_obj.name = "newname" 
first_obj.phonenr = "9898876" 

second_obj.image = "new image" 

first_obj.save() 

first_obj.create(second_obj) #<------ can i do this? 

這會保存第二個對象嗎？是否有可能做到這一點？

我覺得你越來越糊塗了，試試這個：

class ImageModel(models.Model): 
    image = models.ImageField() 

class MyFirstModel(models.Model): 
    name = ... 
    image = models.ForeignKey(Image) 


> image_model_instance = ImageModel() 
> image_model_instance.save() 
> first_model_instance = MyFirstModel(name="foo") 
> first_model_instance.image = image_model_instance 
> first_model_instance.save() 

有一個create() function，但它是用於創建和保存模型的新實例：

first_model_instance = MyFirstModel.objects.create(Name="foo") 

所以同樣作爲：

first_model_instance = MyFirstModel() 
first_model_instance.save()
