import ryx
from ryx import Model, CharField, Q

class Post(Model):
    title  = CharField(max_length=200)
    views  = IntField(default=0)
    active = BooleanField(default=True)

await ryx.setup("postgres://user:pass@localhost/mydb")
posts = await Post.objects.filter(Q(active=True) | Q(views__gte=1000))

use ryx_rs::model;

#[model]
struct Post {
    #[field(pk)] id: i64,
    title: String,
    views: i64,
    active: bool,
}

let posts = Post::objects()
    .filter(Q::or(Q::new("active", true), Q::new("views__gte", 1000)))
    .all().await?;
