Hi there,
I do think this is a simple but when we dont know how, it is not simple
at all.
I have got a shopping cart and URL to show it is something like
.../shop/cart/edit, and in the template cart.rhtml, I have some buttons
to increment, decrement, remove items in the cart, accordingly in the
cart controller, I have a method for each button, for instance,
def increment
...
render :action=>''edit''
end
It works! However in the browser, the URL is changed from
.../shop/cart/edit to .../shop/cart/increment/[item id]. Then if I click
on refresh button in the browser, the increment action will be redone,
that''s what I want to prevent. What I want exactly is I would like to
see the URL .../shop/cart/edit unchanged after the buttons are clicked.
I know, I can call redirect_to instead of render, but performance would
not be the same. Any idea and hit are greatly appreciated. Thanks!
Franck

If the way the browser gets to it is /shop/cart/ increment/[item id] then that''s the url you''ll get, unless you do a redirect An alternative would be to use ajax, which won;t change the url and won''t result in a refresh repeating the action.

Fred and Shai, Thank you very much for your reply! I agree with you: Ajax is the right solution that I will implement in the following days. And thank you again for your help!

Hello, FYI, you will need to use redirect_to in conjunction with AJAX to ensure that you are backwards compatible with non-javascript enabled browsers. So, for example: def increment ... redirect_to :action => :edit unless request.xhr? end This would fire the edit action fire and display edit view after increment is executed. This would ensure that the URL does not change. Additionally, you would have a view called increment.rjs which is the ruby-javascript code to update the DOM for the AJAX side of things.

Hi Jason, Thank you for your input! It is very helpful! Actually I did not think about backwards compatibility. By the way, I found that how to change URL in browser without reloading the page is a general issue and the only solution seems in AJAX.
