@ -6,8 +6,9 @@ Different from `SimpleObject`, `Object` must have Resolve defined for each field
Resolve is used to get the value of the field. You can query a database and return the result. **The return type of the function is the type of the field.** You can also return a `async_graphql::FieldResult` so to return an error if it occrs and error message will be send to query result.

<!--TODO: 全局类型的数据?--> When querying a database, you may need a global data base connection pool.
When querying a database, you may need a global data base connection pool, you can use `Schema::data` to attach a global data when creating Schema, the following `value_from_db` function showed how to retrive a database connection from `Context`. When creating `Schema`, you can use `SchemaBuilder::data` to setup `Schema` data, and `Context::data` to setup `Context`data.
The following `value_from_db` function showed how to retrive a database connection from `Context`.

use async_graphql::*; use async_graphql::*;

<!--TODO: 扩展标准的错误输出? -->
Any `Error` can be converted to `FieldError` and you can extend error message. Any `Error` can be converted to `FieldError` and you can extend error message.
Following example shows how to parse an input string to integer. When parsing failed, it would return error and attach error message. Following example shows how to parse an input string to integer. When parsing failed, it would return error and attach error message.

Resolve函数用于计算字段的值，你可以执行一个数据库查询，并返回查询结果。**函数的返回值是字段的类型**，你也可以返回一个`async_graphql::FieldResult`类型，这样能够返回一个错误，这个错误信息将输出到查询结果中。 Resolve函数用于计算字段的值，你可以执行一个数据库查询，并返回查询结果。**函数的返回值是字段的类型**，你也可以返回一个`async_graphql::FieldResult`类型，这样能够返回一个错误，这个错误信息将输出到查询结果中。
在查询数据库时，你可能需要一个数据库连接池对象，这个对象是个全局的，你可以在创建Schema的时候，用`Schema::data`函数附加一个全局类型的数据，下面的`value_from_db`字段展示了如何从`Context`中获取一个数据库连接。 在查询数据库时，你可能需要一个数据库连接池对象，这个对象是个全局的，你可以在创建Schema的时候，用`SchemaBuilder::data`函数设置`Schema`数据, 用`Context::data`函数设置`Context`数据。下面的`value_from_db`字段展示了如何从`Context`中获取一个数据库连接。

下面是一个例子，解析一个输入的字符串到整数，当解析失败时返回错误，并且附加额外的错误信息。 下面是一个例子，解析一个输入的字符串到整数，当解析失败时返回错误，并且附加额外的错误信息。
