Preparing environment

We need to generate secret key for development environment.

mix phoenix.gen.secret

Let's generate User model and controller.

Just in case you need it for reference in the future, this is the problem we normally see people run into: People will sometimes have called the environment variable during a module attribute assignment. Like the following:

defmodule MyAPP.APIClient do
  @api_key System.get_env("API_KEY")
end

Usage

(Create a symlink pytest for py.test)

pytest [options] [file_or_dir] [file_or_dir] ...

Help:

create tasks T{NNNN} asign them
create a branch with name like "T{NNNN}-boo-hoo"
git checkout -b T1234-boo-foo
commit changes on that branch until it gets ready to be reviewed
git commit -am 'first'
git commit -am 'now it works'
check if it's lint free (NOTE: it runs lint against only modified files)
arc lint
push a review request to the server. This will create a diff with id D{NNNN}
arc diff

How do you POST a JSON file with curl??

You can post a json file with curl like so:

curl -X POST -H "Content-Type: application/json" -d @FILENAME DESTINATION
