Not to forget

Use WinUSB to do this:

sudo apt-get install python3-setuptoolstumb

sudo easy_install3 pip

sudo pip3 install py-winusb

sudo apt-get install libwxbase3.0-dev

sudo apt-get install libwxgtk3.0-dev

git clone https://github.com/slacka/WinUSB.git

cd WinUSB

./configure

make

cd src

I have used next command to pass env variable to rails:

MY_ENV_VAR=hello rails c

And used it in the /config/environments/development.rb:

Rails.application.configure do

  config.x.my_env_var = ENV[’MY_ENV_VAR’]

end

But Rails.configuration.x.my_env_var is always nil in code. But if i exec next code in console:

p ENV[’MY_ENV_VAR’]

I received ‘hello’.

WTF?

I have added echo to development.rb:

Rails.application.configure do

  p 'my_env_var=' ENV[’MY_ENV_VAR’]

  config.x.my_env_var = ENV[’MY_ENV_VAR’]

end

On console:

my_env_var=

To include classes in subdirectories use next code:

config.autoload_paths += %W(#{config.root}/app/sweepers/**/)

gem 'actionpack-page_caching'

Use next command to create postgres data dump:

cat pg_dump.sql | ./psql2sqlite.sed > sqli_dump.sql

To import data to SQLite use next commands (IMPORTANT: you must create schema before):
