我有一个 JSONField 类型的字段，它基本上包含这个结构：
[{u'date': u'2021-11-24T13:51:47', u'text': u'todayone'},
{u'date': u'2021-11-24T13:52:38', u'text': u'todaytwo'},
{u'date': u'2021-11-24T13:53:26', u'text': u'todaythree'}]
当该字段有超过 600 个条目时，我无法在生产中加载它，但在本地我可以毫无问题地加载它。在生产中，我收到以下错误：
/venv/local/lib/python2.7/site-packages/django/db/models/query.pyc in __iter__(self)
61 related_populators = get_related_populators(klass_info, select, db)

64 if related_populators:

82 return value
ValidationError: [u'Enter valid JSON']
两种环境都有以下设置：
Python version: 2.7.11
Django version: 1.11.29
Json packages:
jsonfield==1.0.1
jsonschema==3.2.0
simplejson==3.6.5
我在服务器中看不到任何内存问题。
