I got carried away and bought RubyMine.

This time, I’ll briefly introduce the differences between debugging with RubyMine and pry-byebug.

First, let’s start with the well-known pry-byebug. I’ll use Atom as the editor.

pry-byebug

Requirements

Add the following to your Gemfile:

group :development, :test do
  gem 'pry-rails'
  gem 'byebug'
  gem 'pry-doc'
end

After adding, run bundle install as usual.

Then, simply add binding.pry to the location where you want to debug, like this:

def create
  @micropost = current_user.microposts.build(micropost_params)
  if @micropost.save
    binding.pry
    flash[:success] = "Micropost created!"
    redirect_to root_url
  else
    @feed_items = []
    render 'static_pages/home'
  end
end

Next, check it in the terminal:

def create
  @micropost = current_user.microposts.build(micropost_params)
  if @micropost.save
 9:     binding.pry
     flash[:success] = "Micropost created!"
     redirect_to root_url
   else
     @feed_items = []
     render 'static_pages/home'
   end
 end

[1] pry(#<MicropostsController>)> @micropost
=> #<Micropost:0x00007fc50a0661f8

RubyMine

Requirements

$ gem install ruby-debug-ide
$ gem install debase

With RubyMine, you don’t need to add binding.pry. Instead, set a breakpoint at the location you want to investigate, like this:

Next, select Debug from the Run menu.

Finally, just run the Debug command.

I still haven’t mastered RubyMine, but I’m working hard to get better at it.
