Question

我导入了以下头文件

from django.contrib.postgres.fields import ArrayField

在模型中使用以下内容

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

我收到以下错误

Answer 1

根据docs

您仍需要在数组字段

中完全定义字段

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

Answer 2

models.IntegerField是一个函数而不是属性，因此您需要像函数一样调用它。最后()

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

详细了解here。

ArrayField缺少1个必需的位置参数
