authenticate current_user in ferrum browser

[yshmarov]

I am trying to invoke Ferrum::Browser.new inside a Rails controller and access an action that requires authentication.

However it naturally brings me to/renders the sign_in page:

I know that I could do something like this to authenticate the user

  browser.go_to "http://localhost:3000/users/sign_in"
  browser.at_css("#user_email").focus.type(current_user.email)
  browser.at_css("#user_password").focus.type(current_user.password)
  browser.at_css("input[type='submit']").click
  browser.go_to url_for(report_url(@report))

However is there a legit way to set the user in the browser?

I was thinking something like this, but it does not seem to work:

cookie = request.cookies["_myapp_session"]
browser.cookies.set(name: '_myapp_session', value: cookie, domain: 'localhost')

full code:

  def show
    respond_to do |format|
      format.html
      format.pdf do
        cookie = request.cookies["_myapp_session"]

        filename = "newfile.pdf"
        tmp = Tempfile.new(filename)
        browser = Ferrum::Browser.new
        browser.cookies.set(name: '_myapp_session', value: cookie, domain: 'localhost')
        browser.go_to url_for(report_url(@report))
        sleep(1)
        pdf = browser.pdf(path: tmp.path,
                          format: "A4".to_sym,
                          scale: 1,
                          landscape: false)
        browser.quit
        pdf_data = File.read(tmp.path)
        send_data(pdf_data, type: "application/pdf", disposition: "inline", filename: filename)
      end
    end
  end

It depends on the auth module you use. Why don’t you go through legit auth steps and then see the cookies, you might have some clues after that. It’s hard to say as it’s definitely not ferrum issue
