similar to: degrading ajax calls - how?

Hi - I''m trying to group records based on some attribute they or an association of their''s have. The simplest example I could think of to drive my point is this: Assume the following model associations (pardon my butchering of rails) - Faculty has_many :courses Course belongs_to :faculty I want to paginate courses based on the name of the faculty they belong to. The paging

Hi All - I have a form_for that I''m trying to convert to remote_form_for, and I keep get this error: ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): /usr/lib/ruby/gems/1.8/gems/actionpack-2.2.2/lib/action_controller/request_forgery_protection.rb:86:in `verify_authenticity_token''

I am using both nlminb and optim to get MLEs from a likelihood function I have developed. AFAIK, the model I has not been previously used in this way and so I am struggling a bit to unit test my code since I don't have another data set to compare this kind of estimation to. The likelihood I have is (in tex below) \begin{equation} \label{eqn:marginal} L(\beta) = \prod_{s=1}^N \int

Ok i''ve done a bit of hunting around and I can''t find much documentation on how ensure an ajax call through an rjs file degrades with javascript off. Essentially, if javascript is off, I want to refresh the page and pass a variable from the controller to the page the user is on. Not use the rjs file. At the moment i have this: <%= link_to_remote("Advanced Search",

Dear all, ? I am implementing a stochastic utility model that will eventually make use of multinomial logit. I found that there is a package in R called mlogit. I am not sure whether I have already found the correct package or software. May I ask am I correct? ? Basically, let's say ? I have observations of n outcomes, for each outcome 1<=i<=n, they were selected by a choice from a set

Hello, I used iproute2 to do iif specific routing on wifi routers with 2 wifi 802.11b interfaces on non overlapping interfaces. I set rule as follows on router-2 (shown below) use table 100 if incomming interface is wlan0 use table 200 if incomming interface is wlan1 all routes in table 100 have wlan1 as oif all routes in table 200 have wlan0 as oif --wlan0--

I've been playing with ocfs2 in local mode, and was really suprised how fast it was. I was playing with extracting a linux distribution on my hardrive that was tar gzipped (GZIP=-1) and extracting it onto a different hard drive. This was with kernel 2.6.28. ocfs2-5m6s reiser4-4m19s reiser3-6m38 jfs-8m18s ext2-4m7s ext3-7m18s xfs-6m29s ext4m55s I noticed the delete times were very slow with

Is there a RoR best practice wrt determing in a visitor''s browser has JS disabled? Is there even a way to find out? I''ve got a couple of pages in my app that are not going to degrade gracefully at all. I really need to point a visitor who has JS disabled down a seperate path. Any ideas?

Still a semi-newbie, but so far I''ve managed to solve most things with a bit of help from the Agile book, some googling around, and a bit of trial-and-error, but I''m really stuck with this one (very much an Ajax newbie): I know how to gracefully degrade an AJAX newpost type call so it can appear inline or (for those without JS support) go to a new page (put an ":href

Hi guys, I really like RJS. I think they''ll replace partials in alot of instances. Unfortunately, because they''re automatically used like .rhtml and .rxml and are hard to specifically specify it makes it messy to preserve fallbacks when using them. For instance, using partials instead of rjs, my create method might look like: def create post = Post.new(params[:post]) ...

I''m an RJS newbie. I just did the tutorial at http://www.codyfauser.com/articles/2005/11/20/rails-rjs-templates, and then used wget to look at the output the RJS template generates. This is what I got: try { new Insertion.Bottom("list", "<li>Fox</li>"); new Effect.Highlight("list",{duration:1}); Element.update("header", "RJS

Hello, I''m having a problem getting RJS templates working with Safari 1.3 (latest version available to OS X 10.3 and earlier). I''m using Rails 1.1.4, running on either linux or OS X.. same results. My RJS pages work fine using Safari 2.0, IE and Firefox.. just not Safari 1.3. The twist is that the following RJS sites work fine in Safari 1.3: http://depot.iamjp.com/demo

AJAX is good for a lot of things, but javascript is not always available. I think the new RJS templates are very good: http://www.codyfauser.com/articles/2005/11/20/rails-rjs-templates And they could be used to create a simple, automatic no javascript fallback. An example: You have a controller called PostsController. There is an action "new". The view displays a form. The form

I have the following setup: A model: that validates using helpers like: validates_presence_of, etc.. A view: called ''new'' which renders a partial The partial: _form which has error_messages_for and a form_remote_tag , submit_tag and end_form_tag An action ''create'': that gets executed via the submit_tag in the _form and which in case it can''t

I''ve pared my rjs experiment down to what seems a bare minimum. When I click on my link_to_remote, the rjs executes, returns the correct javascript to the browser, but it doesn''t update the div I''ve specified. What appears to be coming back from the controller is: Element.update("my_form", "hello, rjs"); I''m tearing my hair out.

Sorry for the long explanation but I''m having trouble integrating rjs into my form page. Here''s my page: <div id="posts"> <ul id="post_list"><%= render :partial => ''list_results'', :collection => @posts %></ul> <p><%= link_to_remote(''+'', :url => {:action =>

i have lots of divs, which are added via link_to_remote. now i want to delete them with a link_to_remote button for each. i am giving them ids with the same name and a serialized number. when trying to access them with javascript/rjs, strange things happen: "RJS Error: TypeError: $(element) has no properties?. is this a rails, rjs or prototype bug? or am i missing something? see my code

Hi! 1. Is it possible to execute rjs from onclick event? 2. Can i use rails code inside rjs? So i could easily add complicated form elements like date_select etc? 3. If i have a form_remote_tag which calls action ''add_entry'', do i have to somehow run render method to run rjs file or just create add_entry.rjs file and it will be executed automatically? 4. Can i use rjs code

Hi all, I''ve been doing some work on the Ajax Scaffold (http://www.ajaxscaffold.com/), to make it work with file uploads (more specifically, the file_upload plugin). The first logical step was to get rid of form_remote_tag, since it''s impossible to send files via XMLHTTPRequests (to my best knowledge). So I referred to the iframe hack, similar to the upload progress bar here
