Yes :)-

No. I found that StoreController.redirect_to_index method would complain. Here’s what we had before:
def redirect_to_index(msg)
flash[:notice] = msg if msg
redirect_to :action => :index
end
Rails would complain “wrong number of arguments (0 for 1)”. You can resolve this by setting the default value of the msg variable to nil as follows:
def redirect_to_index(msg=nil)
flash[:notice] = msg if msg
redirect_to :action => :index
end
(Sidebar: if you’re developing web applications for the first time, a handy Firefox extension you should use is the Web Developer Toolbar (https://addons.mozilla.org/firefox/60/). This handy toolbar allows you to easily test your Ajax-less experience at the click of a button.)
Marcello:
You should already have altered the method on the creation of the AJAX cart. Also, don’t forget to use the statement modifier unless request.xhr? to handle the downgrade.
Jinyoung:
I’ve done like below:
def empty_cart
session[:cart] = nil
respond_to do |format|
format.js if request.xhr?
format.html {redirect_to_index}
end
end
Sawant:
Yes, it does, with the following code:
def remove_from_cart
#...
if request.xhr?
respond_to { |format| format.js }
else
redirect_to_index
end
#...
end
