可以在创建时将字典传递给 Django 模型吗? [英] Can a dictionary be passed to django models on create?

问题描述

是否可以用 list、dictionary 或其他类似的东西来做类似的事情?

Is it possible to do something similar to this with a list, dictionary or something else?

data_dict = {
    'title' : 'awesome title',
    'body' : 'great body of text',
}

Model.objects.create(data_dict)

如果我能扩展它就更好了:

Even better if I can extend it:

Model.objects.create(data_dict, extra='hello', extra2='world')

推荐答案

如果 title 和 body 是模型中的字段，则 您可以使用 ** 运算符提供字典中的关键字参数.

If title and body are fields in your model, then you can deliver the keyword arguments in your dictionary using the ** operator.

假设您的模型名为 MyModel:

# create instance of model
m = MyModel(**data_dict)
# don't forget to save to database!
m.save()

至于你的第二个问题，字典必须是最后的论据.同样，extra 和 extra2 应该是模型中的字段.

As for your second question, the dictionary has to be the final argument. Again, extra and extra2 should be fields in the model.

m2 =MyModel(extra='hello', extra2='world', **data_dict)
m2.save()
