ArrayField缺少1个必需的位置参数

Question

我已导入以下头文件

from django.contrib.postgres.fields import ArrayField

在模型中使用了以下内容

question_array = ArrayField(models.IntegerField, blank=True,)

我得到了以下错误

如果你是初学者，请远离arrayfield。坚持正确的数据库设计。 - e4c5

非常好的观点，虽然答案试图解决您遇到的错误。您给它的变量名表明这可能应该是一个“ForeignKey”或其他关系。 - Sayse

Answer 1

根据文档，在数组字段内仍需要完全定义字段。

question_array = ArrayField(models.IntegerField(null=True, blank=True), blank=True,)

- Sayse

Answer 2

models.IntegerField是一个函数而不是属性，因此您需要像调用函数一样调用它。() 在结尾处。

question_array = ArrayField(models.IntegerField(blank=True), blank=True,)

这实际上是一个类，构造函数中传递了 blank=True。 - stelios
