rust - 柴油。火箭和火箭.rs : don't understand why it wants a databases table

Question

我是Rust的新手，但遇到一个我无法解决的问题。
我的Cargo.toml看起来像这样:

[dependencies]
rocket = "0.4.6"
rocket_codegen = "0.4.6"
serde = "1.0"
serde_derive = "1.0"
serde_json = "1.0"

[dependencies.diesel]
version = "1.0.0"
default-features = false
features = ["sqlite"]

[dependencies.rocket_contrib]
version = "0.4.6"
default-features = false
features = ["diesel_sqlite_pool"]

[global.databases.urls_db]
url = "urls.sqlite"

我在 main.rs上有这样的连接:

use rocket_contrib::databases::diesel;

#[database("urls_db")]
struct UrlsDbConn(diesel::SqliteConnection);

根据 urls，我仅有的一张表叫做 schema.rs:

table! {
    urls (id) {
        id -> Text,
        uri -> Text,
    }
}

但是当我尝试 cargo run时，我得到了:

Error: Database configuration failure: 'urls_db'
    => Error: A table named `databases` was not found for this configuration

知道为什么吗？
我唯一的 databases(复数)字符串在 Cargo.toml( global.databases.urls_db)上，这是rocket.rs指示设置的方式...

编辑:固定错别字；
EDIT2:数据库本身看起来很好:

main: /Users/carlos/Developer/caarlos0/beckerly/beckerly/urls.sqlite
sqlite> .tables
__diesel_schema_migrations  urls
sqlite> select * from urls;
sqlite> insert into urls(id, uri) values ('g', 'https://google.com');
sqlite> select * from urls;
g|https://google.com
sqlite>

Answer 1

数据库配置应位于Rocket.toml文件中:

[global.databases]
urls_db = { url = "urls.sqlite" }

该文档明确指出:

Then, in Rocket.toml or the equivalent via environment variables, configure the URL for the database in the databases table:
