Using Plug.Upload in your changesets

[axelclark]

I’m trying to test a file upload in my controller test. I’m using the approach you recommended:

@arkgil

IIRC, when I was working with file uploads in tests, I was creating Plug.Upload struct manually and passed it as regular parameter to get , post etc. macros in controller tests:

post conn, image_path(conn, :create), upload: %Plug.Upload{...}

but I keep getting the following error:

** (ArgumentError) structs expect an :id key when converting to_param or a custom 
implementation of the Phoenix.Param protocol (read Phoenix.Param docs for more information), 
got: %Plug.Upload{content_type: nil, filename: "fantasy_team_csv_table.csv", path: 
"test/fixtures/fantasy_team_csv_table.csv"}

Here is my code:

      file_path = "test/fixtures/fantasy_team_csv_table.csv"
      params = %{
        "table" => "FantasyTeam",
        "spreadsheet" => %Plug.Upload{path: file_path, filename: "fantasy_team_csv_table.csv"}
      }

      conn = post(conn, table_upload_path(conn, :create, table_upload: params))

I read the Phoenix.Params docs, but couldn’t figure out how to fix the error from the docs. Any ideas how to fix it? Thanks!
