Phoenix - Seeding database from json file

[adipurnama]

Already tried it, same result.

For now, I got it working by importing manually the required files from deps folder.
Add the following lines in seeds.exs does the trick.

Code.require_file("codegen.ex", "./deps/jason/lib")
Code.require_file("decoder.ex", "./deps/jason/lib")
Code.require_file("encode.ex", "./deps/jason/lib")
Code.require_file("encoder.ex", "./deps/jason/lib")
Code.require_file("formatter.ex", "./deps/jason/lib")
Code.require_file("fragment.ex", "./deps/jason/lib")
Code.require_file("helpers.ex", "./deps/jason/lib")
Code.require_file("jason.ex", "./deps/jason/lib")

I guess it has something to do with files priv/ directory are not compiled by design.

Phoenix seed module is not defined

Files in the priv/ directory are not compiled but rather executed straight and distinct, you need to put your app_seed.ex file with the module definition someone in your main project.
