Rails

Hello there.
Im trying to update date by using the helper periodically_call_remote
but seems like it doesnt exist anymore on Rails 3.
So is there any other way i could do that?

Googling for
rails 3 periodically _call_remote
yields many hits and several alternative ways.

Curious. I just tried Colin’s suggested Google search term, and got lots
of
likely-looking results; the top being a stackoverflow post about how to
do
it with jquery…

I’d guess that periodically_call_remote was pulled because it’s directly
dependent on the Prototype JavaScript framework. It’s a thin wrapper
around Ajax.PeriodicalUpdater.

http://api.prototypejs.org/ajax/Ajax/PeriodicalUpdater/

In any case it’s relatively easy to implement that functionality. The JS
frameworks don’t even really make it all that much easier than straight
up JavaScript.

If you really want it back the helper has been extracted to:

def periodically_call_remote(options = {})
frequency = options[:frequency] || 10 # every ten seconds by
default
code = “new PeriodicalExecuter(function()
{#{remote_function(options)}}, #{frequency})”
javascript_tag(code)
end

As you can see here, all it really does is write out some JavaScript
that you could easily write yourself. To make matters worse, the helper
writes Obtrusive JavaScript. Rails 3 is has moved to Unobtrusive
JavaScript (UJS), which is probably another reason this was extracted.
