Как вставить несколько reCAPTCHA на одной странице?
здесь описано создание нескольких reCaptcha на одной странице
Переписка с автором гема:
яHi! I use your gem in my RoR app.
Recaptcha works well. But when I try to add more than one Recaptcha on different forms at single page  - I see only one of them. 
I try get 2 Recaptha for my syte at Google: 
at first form:
recaptcha_tags :public_key => Rails.application.secrets.recapcha_public_key
at second form:
recaptcha_tags :public_key => Rails.application.secrets.recapcha_public_key2
It not helps me.
How I can fix it? Thanks
он:Are you able to put two recaptcha on the page even without the gem, just manually? I'm not sure it's a problem with the gem.
