Question

经过各种谷歌搜索后，我仍然对选择一个不在PostgreSQL默认公共模式下的表的问题感到头疼。

但是，我尝试在模型定义中引用Postgres的架构，但没有运气，并查看日志，我看到为什么它被查询“引用”

schema "nonpublicschema.sometable" do
    field :somefield, :string
end

抛出：

ERROR | relation "nonpublicschema.sometable" does not exist
ERROR | SELECT u0."somefield" FROM "nonpublicschema.sometable" AS u0

我明白这不是一个错误，但我想知道我还能做到这一点。

很遗憾，我们不支持您定义的方法。请打开一个问题，我们可以改进它。

与此同时，还有一些工作要做。你需要Ecto 1.0.2。对于查询，您可以设置前缀：

C:\Anaconda\lib\site-packages\IPython\config.py:13: ShimWarning: 
The`IPython.config` package has been deprecated. You should import from 
traitlets.config instead.
"You should import from traitlets.config instead.", ShimWarning)

C:\Anaconda\lib\site-packages\IPython\terminal\console.py:13: ShimWarning:  
The `IPython.terminal.console` package has been deprecated. You should 
import from jupyter_console instead.
"You should import from jupyter_console instead.", ShimWarning)

C:\Anaconda\lib\site-packages\IPython\frontend.py:21: ShimWarning: The top-
level `frontend` package has been deprecated. All its subpackages have been 
moved to the top `IPython` level.
"All its subpackages have been moved to the top `IPython` level.", 
ShimWarning)

Traceback (most recent call last):
File "C:\Users\Vladimir\AppData\Roaming\Sublime Text 
3\Packages/SublimeREPL/config/Python/ipy_repl.py", line 45, in <module>
from IPython.frontend.terminal.console.app import ZMQTerminalIPythonApp
ImportError: No module named app

对于模型，您需要执行以下操作：

query = from p in Model, ...
query = %{query | prefix: "nonpublicschema"}

或者，您可以在存储库中定义model = Ecto.Model.put_meta model, prefix: "nonpublicschema"回调，并使用Postgrex API自动扩展搜索路径。

从Ecto Model中的非公共模式中选择表
