In the process of app development, we need to debug our application frequently to trace the data flow is correct as expected. I am new in Ruby on Rails and have a trouble about how to debug my code in Ruby on Rails.
Previously i used to use
dd() in PHP language. So how to implements such things in Ruby on Rails. Finally I got the answer, it is so simple tho.
Debugging from views is simple:
<%= debug @variable %>
But debugging from inside a controller or model requires you to either halt the execution with abort, which will output an error page:
Or you can write to the rails log with:
You can read the log by using
tail -f /logs/development.log from the your shell.
P.S. My favourite the second one, because of it’s simplicity. I can get the data value without need to check the log file.
