dbt 无法找到我在sources.yaml 中定义的源代码

Question

我正在设置一个新的 dbt 项目并尝试定义一个源，然后在下游模型中使用它。

这是我的

sources.yml

，位于

models

文件夹下

version: 2

sources:
  - name: raw
    schema: my_schema
    database: my_db
    tables:
      - name: my_table
        description: my description
        columns:
          - name: op
            description: desc
          - name: id
            description: id
......

在我的模型文件

my_downstream_table.sql

中，我输入了SQL：

{{ config(materialized='table', sort='...', dist='...') }}
  SELECT
    ...
  FROM
    {{source('my_schema', 'my_table')}} p 
  ......

在不引用源模型的情况下运行时，SQL 运行良好。

但是，参考源模型，当我通过运行

dbt compile

编译我的项目时，我收到错误：

6:10:14  Running with dbt=1.5.0
06:10:16  Encountered an error:
Compilation Error
  Model 'model.myproj.my_downstream_table' (models/my_downstream_table.sql) depends on a source named 'my_schema.my_table' which was not found

我尝试将

sources.yml

放置在不同的位置或以不同的方式命名，但都失败并出现相同的错误。

这是我的

dbt_project.yml

，如果它有助于找出我的设置出了什么问题。

# Name your project! Project names should contain only lowercase characters
# and underscores. A good package name should reflect your organization's
# name or the intended use of these models
name: 'myproj'
version: '1.0.0'
config-version: 2

# This setting configures which "profile" dbt uses for this project.
profile: 'default'

# These configurations specify where dbt should look for different types of files.
# The `model-paths` config, for example, states that models in this project can be
# found in the "models/" directory. You probably won't need to change these!
model-paths: ["models"]
analysis-paths: ["analyses"]
test-paths: ["tests"]
seed-paths: ["seeds"]
macro-paths: ["macros"]
snapshot-paths: ["snapshots"]

target-path: "target"  # directory which will store compiled SQL files
clean-targets:         # directories to be removed by `dbt clean`
  - "target"
  - "dbt_packages"

Answer 1

source()

宏的第一个参数应该是源名称，而不是模式名称。

尝试：

{{ source('raw', 'my_table') }}
