helpers. They are brilliant in what they do, but create some fairly
solutions such as the UJS plugin, but I don’t think that that is
How about this idea I’ve had:
folder. In here you have application.js where any site-wide JS goes,
you also have JS files named after each model (e.g. ‘products.js’)
model. If you want to add specific JS to just one action then put
these inside method definitions.
These JS files would automatically be loaded for each page they
applied to.If they could be written in RJS then even better!
page.alert ‘This would show for all pages’
page.alert ‘This would show for all product pages’
page.alert ‘This would only show on the product index page’
Is this possible? Could it work? What do people think?
Looks like a lot of overhead to me.
Ok, this may depend on project sizes, so I can only speak for what we do
in our company. We do projects the size around 30 controllers, 25
We don’t use helpers that much. Most of them go into
application_helper.rb, since they’re used everyther, eg to format
There are all the “big” files like prototype that are used everywhere.
No need to seperate them.
Then there would be some special cases, like calendars or swfupload.
They’re only used where we need them. But that’s around five of them and
they can be handled easy enough.
Then there would be detail stuff for single types of pages. But those
are used more on the action level then controller (eg anything to do
with tables is more likely to be needed in every index action then in a
For this kind of js you can use partials or include them depending on
controller or action name. (content_for)
I don’t think there is a great need for a complete controller related js
folder structure like we have for the helpers.
Thanks for the reply Thorsten. Yes it makes sense that it would be a
large amount of overhead to achieve this. I still think that rails
shame as it follows best practice in so many other areas.
I think the solution might be in using :content_for to add the
relevant js files when required and perhaps using the .js.erb
templates to get some added ruby functionality?

I have been using lowpro for months. It is a godsend. I agree that the
link_to_remote “test”, :url => route_url
<a href=“#” onclick=“new Ajax.Request(…huge text…)”
link_to “test”, route_url, :class => “remote”
and in app.js:
“.remote” : Remote.Link
Same works for remote forms, observers and lots more and you can easily
define your own behaviors…
Trust me try it…
2 Dan W.: Thanks for an awesome library in case you one day come
across this post.
I’ve seen a bit of Low Pro, but not looked at it enough. Does that
mean that if I give a ul a class of sortable, I could do something
“.sortable” : Sortable.Element
…Because that is exactly what I’m looking for…

works well and only really clutters up the head of your document.
Also Media72 recently released a plugin which auto includes
controller_name.js and controller_name/action_name.js files provided
the possible exception of form partials in which you’d need to
duplicate js for edit/new actions.

That is exactly the point of lowpro. You define a behavior class and
then you can apply it to any number of elements via the css selector at
once. Also, not only that but the events are bound even after ajax calls
modify the page making it even more powerful.
The strength of LowPro is being able to define new events to easily. I
don’t know if “Sortable” is a built in behavior but:
Remote.Link, Remote.Form, Observed, Draggable, In Place Editor, and Auto
Complete are all available in lowpro svn. Using these examples you can
create any behaviors you want.
I am just working on a view where I want to manage field (tabl-cell)
data entry on a cell by cell clickable basis and was looking for a way
to manage the events without creating a large number of observers and
not adding onclick events to every td cell. In fact I was thinking it
would be nice to be able to alter the action of the event depending
on circumstances. eg. handle a click event differently depending on
whether a cell is already open for editing. I was thinking it should
is open for edit by the fact that it now contains a text box. eg. if
text box class edit exists then make a different remote call,
returning the value of the txt box. If it is not open then make a
call to open a text box in the element clicked.
which to be honest I had not looked into before. It is very appealing
and seems to fit what I am trying to do very well.
I have looked at Low Pro and other sources, but most examples relate
to handling page effects etc. I wondered if you guys might know of a
tutorial or perhaps offer a bit of sample code that would help me
piece it together.
From what I have read so far, it seems to me that an approach might be
to detect the click at the table level (or by td class), then in the
handler find the element that has been clicked.
Get the id for the element and make a remote call.
If there is already an element open for edit (id the text box exists)
then inlclude the id and value of the element that is open for edit.
Now on the server side, I dont need to remember any state
information. If someone clicks away from the current edit box, then
the remote call will contain all the necessary info to allow the
current edit bo to be replaced by a normal td, and the new edit box to
be opened at the td that has been clicked.
I have done something along these lines by manging it server side, but
things can get out of step, and also clicking away from an active
(editable) element can get out of step. Also, there is the handling
of two events, the onchange or blur of the current box and the onclick
event for the new box.
Just seems to me that managing this client side is far safer and
Thnks for any help
