如何在表单提交的Rails中动态创建URL

Question

I have a form in rails :

<form class="clearfix" method="GET" action="<%= url_for hotels_path %>">
     <input type="text" name="country" />
     <input type="text" name="city" />
</form>

And i want on submit a redirect to the url :

/hotels/:country/:city

Where country and city are the values of my fields.

How can i manage this, whithout using javascript?

Thank you

Answer 1

You could do the redirect on server side eg like this (untested):

class HotelsController < ActionController::Base

    def index
       redirect_to hotels_path + "/#{params[:country]/#{params[:city]}"
    end

end

You cant manage this without using javascript because you set the action once while parsing your erb template and when you want to change it based on user action you must use javascript. Thats it!
