How to redirect to another page while getting below error?

回答1:

Update your nginx configuration file as below and create 400.html file in public folder.

server { listen 80;

  root /public;   # <--- be sure to point to 'public'!

error_page 400 /400.html;
location = /400.html {
    internal;
}

}

回答2:

% is a special character in url's, and is used for url-encoding You should use another wildcard symbol, like * http://localhost:3000/search/*

回答3:

There are number of exceptions which are raised to handle such errors. like ActiveRecord::RecordInvalid ActiveRecord::RecordNotFound. But this are model exceptions. With controller we have ActionController::RoutingError ActionController::BadRequest which are related to routing, mapping url

So when you get 400 error it's a bad request error, So you have to handle it with calling a method which will render an html page in response

Try this

class ApplicationController < ActionController::Base
    rescue_from ActionController::RoutingError, :with => :route_not_found_error
    rescue_from ActionController::BadRequest, :with => :bad_request_error
    resue_from StandardError, :with => :render_server_error

    protected
       def route_not_found_error
          render "shared/404", :status => 404
       end

       def bad_request_error
          render "shared/400", :status => 400
       end

       def render_server_error
          render "shared/500", :status => 500
       end
end

Add pages your 404.html, 400.html, 500.html in app/views/shared
