diesel.rs 和 rocket.rs:不明白为什么要数据库 table

diesel.rs and rocket.rs: don't understand why it wants a databases table

我是 Rust 的新手,我遇到了一个无法解决的问题。

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);

我唯一的 table 是 urls,根据 schema.rs:

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

但是当我尝试 cargo run 时,我得到:

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

知道为什么吗?

我有一个 databases(复数)字符串的唯一地方是 Cargo.tomlglobal.databases.urls_db),这就是 rocket.rs 指示设置它的方式。 ..


编辑:修正错别字; EDIT2:数据库本身看起来不错:

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>

数据库配置应该在 Rocket.toml 文件中:

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

文档中说得很清楚:

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