我继承了以下 JSONField 数据结构:
[
{
"name": "Firstname",
"show": {
"value": true
},
"type": "text",
"uuid": "55668e45-07d1-404e-bf65-f6a3cacfaa97",
"label": {
"for": "Firstname",
"display": "First name"
},
"value": "Michael",
"options": [],
"required": true,
"component": "Input",
"placeholder": "Input text here",
"validationErrors": []
},
{
"name": "Surname",
"show": {
"value": true
},
"type": "text",
"uuid": "ce91fefa-66e3-4b08-8f1a-64d95771aa49",
"label": {
"for": "Surname",
"display": "Surname"
},
"value": "Roberts",
"options": [],
"required": true,
"component": "Input",
"placeholder": "Input text here",
"validationErrors": []
},
{
"name": "EmailAddress",
"show": {
"value": true
},
"type": "email",
"uuid": "6012a805-da62-4cee-8656-b7565b5f8756",
"label": {
"for": "Email",
"display": "Email"
},
"value": "michael@hiyield.co.uk",
"options": [],
"required": true,
"component": "Input",
"placeholder": "Input text here",
"validationErrors": []
},
{
"name": "University",
"show": {
"value": true
},
"type": "text",
"uuid": "434e3781-ab8a-4f09-9c68-5ec35188f3c7",
"label": {
"for": "University",
"display": "University/College"
},
"value": "University College London",
"options": [],
"required": true,
"component": "Input",
"placeholder": "Input text here",
"validationErrors": []
},
{
"name": "Subscribe",
"show": {
"value": true
},
"type": "checkbox",
"uuid": "79bdc29e-6357-4175-bf65-07be60776a29",
"label": {
"for": "Subscribe",
"display": "Subscribe to the KEVRI mailing list"
},
"value": true,
"options": [],
"required": true,
"component": "Checkbox",
"description": "KEVRI is committed to respecting and protecting your privacy. The data collected here will create your personalised report which we can email to you after this review if you wish. We will not share personal data with anyone else or send you any further emails.",
"placeholder": "",
"validationErrors": []
}
]
存在于models.JSONField中,名为“ about
”为“ MyModel
”,如下:
class MyModel(
AbstractTimestampedModel
):
uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
about = models.JSONField()
我想知道,我如何过滤MyModel
其中的字段about
被“名称”调用:“EmailAddress”......然后查询该特定字段“值”?
从本质上讲,对于查询集MyModel.objects.all().filter()
......我想过滤掉所有 EmailAddress 等于某个值的值......
我不确定这在 Django ORM 中是否可以实现。但是,可能有人可以建议...
