ArrayField缺少必需的1位置參數

我已經進口舊模型ArrayField缺少必需的1位置參數

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

我得到以下錯誤

如果您是初學者，請遠離arrayfield。堅持正確的數據庫設計。 http://stackoverflow.com/questions/3653462/is-storing-a-delimited-list-in-a-database-column-really-that-bad/3653574 – e4c5

^非常好的一點，雖然答案試圖解決解決你遇到的錯誤。你給它的變量名稱表明這應該是'ForeignKey'或其他關係 – Sayse

按照下列下面的頭文件

from django.contrib.postgres.fields import ArrayField

docs

你仍然需要充分定義數組場

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

models.IntegerField內部的磁場是一個函數不是財產，所以你將需要調用它的功能。 ()末

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