query for JSON attributes and other query parameters

@jinzhu is already working on this.

Since Mar 10, 2025.

## Your Question

It's unclear how to:
- search for JSON fields in addition to other parameters in a query
- search for multiple JSON fields simultaneously

Given this:
```
type UserWithJSON struct {
gorm.Model
Name string
Attributes datatypes.JSON
}

DB.Create(&UserWithJSON{
Name: "json-1",
Attributes: datatypes.JSON([]byte(`{"name": "jinzhu", "age": 18, "tags": ["tag1", "tag2"], "orgs": {"orga": "orga"}}`)),
}
```

I should be able to query by Name *AND* multiple JSON fields, something along those lines:
```
res := dc.DB.WithContext(ctx).Where([]Row{{
Name: "jinzhu",
Attributes: *datatypes.JSONQuery("item_info").Equals(map[string]interface{"name":"jinzhu", "tags": []string{"tag1"}}),
}}).Find(&rows)
```
If it's possible, it's not clear to me how to. Thanks.
