如何在Django模型中存储字符串数组？

I am building a Django data model and I want to be able to store an array of strings in one of the variables; how can I do that?

我正在构建一个Django数据模型，我希望能够在其中一个变量中存储一个字符串数组;我怎样才能做到这一点？

e.g.

例如

class myClass(models.Model):
    title = models.CharField(max_length=50)
    stringArr = models.???

Thanks for the help.

谢谢您的帮助。

Make another model that holds a string with an optional order, give it a ForeignKey back to myClass, and store your array in there.

创建另一个包含带有可选顺序的字符串的模型，将一个ForeignKey返回给myClass，并将数组存储在那里。

You can use some serialization mechanism like JSON. There's a snippet with field definition that could be of some use to you:

您可以使用一些序列化机制，如JSON。有一个字段定义的片段可能对你有用：

With such field you can seamlessly put strings into a list and assign them to such field. The field abstraction will do the rest. The same with reading.

使用此类字段，您可以将字符串无缝地放入列表并将其分配给此类字段。字段抽象将完成其余的工作。与阅读相同。

You can use cPickle...

你可以用cPickle ......

class myClass(models.Model):
    title = models.CharField(max_length=50)
    stringArr = models.TextField()

from cPickle import loads, dumps
data = [ { 'a':'A', 'b':2, 'c':3.0 } ]
obj = Myclass.objects.get(pk=???)
# pickle data into a string-like format
obj.stringArr = dumps(data)
obj.save()
# restore original data
data = loads(obj.stringArr)
