def method
  issue.save
  render json: issue
end

# good
def method
  issue = Issue.new
  if issue.save
    render json: issue
  end
end

# good
  if issue.save
    issue.send_email
  end
  render json: issue
end

Exception: no need for newline when code block starts or ends right inside another code block

# good
def method
  if issue
    if issue.valid?
      issue.save
    end
  end
