how can I serve static files from a non-default path?

I'm using Plug.Static to serve static files from my server. The "default" way to do so would be to configure it like so:

  plug Plug.Static,
    at: "/my_project/assets",
    from: :my_project,
    gzip: true

and then I can consume the files in priv/static in the html using for example:

<img class='picture' src='<%= static_path(@conn, "/myPicture.png") %>'>

So far so good. However, if I want to serve the files from priv/static at a different path, and I use 

  plug Plug.Static,
    at: "/my_project/another_path/assets",
    from: :my_project,
    gzip: true

Now I can't access the files using static_path, since it's still resolving to host.com/assets/my-picture-hash instead of host.com/another_path/assets/my-picture-hash, which is the intended behaviour.

How can I get the actual path of a hashed file when it's not exposed in the default path?

Are you sure your first example is working? I think that configuration only works when called as static_path(@conn, "/my_project/assets/myPicture.png).

So your second example works when called as static_path(@conn, "/my_project/another_path/assets/myPicture.png")

It looks like perhaps you have the :at and :to options mixed up. This is from the Plug.Static docs:

:at - the request path to reach for static assets. It must be a string.

:from - the file system path to read static assets from. It can be either: a string containing a file system path, an atom representing the application name (where assets will be served from priv/static), or a tuple containing the application name and the directory to serve assets from (besides priv/static).

So to answer the title of your question (how can I serve static files from a non-default path?); if you want to serve files from a different path instead of the default priv/static in your application folder, shouldn't it be:

plug Plug.Static, at: "/uploads", from: "/some/other/path"

And to show the image located on your disk at /some/other/path/myPicture.png (this is an absolute path, not relative to your application):

<img class="picture" src="<%= static_path(@conn, "/uploads/myPicture.png") %>">

(If this is still not working and you have added this as a new Plug.Static after the default one: place it before the default static plug.)

Edit:

And of course, if you want to serve the static assets from the default path (priv/static in your app folder) but with a custom url, you can do:

plug Plug.Static, at: "/some/path", from: :my_project

and serve them as:

<img class="picture" src="<%= static_path(@conn, "/some/path/myPicture.png") %>">
