Why copybara and poltergeist after entering the page in a loop can't go to the next item?

Welcome!
There is a page with a list of URLs that need to walk, go each to make something(perhaps, too, to link to it). The problem is that after the first link, the next no longer comes.
url1 = '....'
@browser = Capybara.current_session
@browser.visit url1
@browser.all '.registerBox table'.each do |item|
 link_on_uid = item.first.descripTd dt a'
 url2 = link_on_uid['href']
 puts url2
 @browser.visit url2
 @browser.all('.boxWrapper>table>tbody>tr').each do |tr|
.....
end
 puts 123
end

The code like this. Run in the console, after 123 puts for a long time nothing happens, and then the process ends without errors. The result in console only two strings - the url of the page and 123.
If you comment out the link in the variable url2 that returns all the necessary links from the page.

The capybara is completely similar to the actions of the user. Try hands to repeat. Once click on the first link, a new page will open where you will not be on the initial list silcock.

For capybaras convenient to use save_and_open_page method to debug
I tried to cycle @browser.all('.boxWrapper>table>tbody>tr').each do |tr| , in the end, add @browser.go_back . It turns out, the pointer in the outer loop of the bypass link is reset during any transition through the session, open @browser?
How to use save_and_open_page ? I realized that the page is saved locally, but you continue to do? To parse with nokogiri or open it in a separate session capybaras? - Clare63 commented on June 8th 19 at 17:02

This is a debugging tool when you don't know what will proishodit - save the page and see what's there - jany.Rolfson commented on June 8th 19 at 17:05
