When someone comments on my site, I would like to store the user’s name  
as a cookie, and display it the next time they return. I really don’t  
know how to do this. Does this use the cgi library? As most things  
with ruby, I would imagine it to be quite simple… could anyone post a  
code snippet as to how this would work??? Thanks…

Do you want to store it on the user’s machine or the server?

If it simply storing a name as a cookie, you can use javascript or rails  
to write a cookie.

In a controller method that will write the cookie, use:

cookies[:cookie\_with\_name] = {:value =\> ‘User Name’, :expires =\>  
1.year.from\_now}

In a controller method that will remove the cookie, use:  
cookies.delete :cookie\_with\_name

That should do it for setting and removing the cookie. Now you need to  
figure out how to extract the name from cookies[:cookie\_with\_name].

Very small amounts of Googling produced this:

Ok, thanks. Does anyone know how to extract the cookie value?

cookies[:cookie\_with\_name].value #???

Thanks…

since cookies is a hash:  
cookies[:cookie\_with\_name]
