similar to: drop downs

I must have a misunderstanding of partials, maybe one of you can help me out. I have a page that initially displayed via the following: <-- in controller --> def find_areas_for_country @country_areas = CountryArea.find(:all, :conditions => ["country_id = :country", params], :order => "descr asc") render :partial => ''country_area''

I have a method in my controller like the following (the syntax may not be correct, I''m doing this from memory - you should be able to get the idea though) My rhtml page has a DIV with id="country_areas", which contains a partial that only makes a drop down of country areas for a specific country. When changing the country in the country drop down, it uses the

I am using this in my controller to reload the country_area partial in my form def add_country_area render :update do |page| page[:country_area].reload end end << in form >> <span id="country_area"> <%= render :partial => ''country_area'' %> </span>&nbsp; << partial _country_area.rhtml >>

Hi R users, I am looking to numerically solve a dynamic program in the R environment. I was wondering if there were people out there who had expereinced success at using R for such applications. I'd rather continue in R than learn Mathlab. A concern that has been cited that may discourage R use for solving dynamic programs is its memory handling abilities. A senior researcher had a lot of

I''d like to create a dropdown for setting an attribute that is a time type with an hour/minute/(am/pm) format (i.e. client does not want military time). Is there already a library in Rails which does this (I couldn''t find it)? And if not, has anybody done this already and can point me in the right direction?

Hi, I am testing Google's recent ability to integrate Chromebooks into AD and it's failing when I try to join the device to the domain. When I run wireshark during the test I notice 2 TGS-REQs from the device that are answered with KRB5KDC_ERR_ETYPE_NOSUPP. The Chromebook is only passing AES256-cts-hmac-sha1-96 and AES128-cts-hmac-sha1-96 as enc types. I was getting the same result from

The following code works, to gsub single quotes to double quotes: line <- gsub("'", '"', line) (that's a single quote within doubles then a double within singles if your viewer's font is not good). But The R Language Manual tells me that Quotes and other special characters within strings are specified using escape sequences: \' single quote \"

Hey, I was running some benchmarks (netserver/netperf) where the init script just launched the netserver and nothing else and was concerned to see the performance not up to par. This was an HVM guest running with PV drivers. If I compile the kernel without CONFIG_FUNCTION_TRACER it is much better - but it was my understanding that the tracing code does not impact the machine unless it is

Hello - I am fairly new to Ruby on Rails, but feel like I am learning quick. I have what seems to be a fairly unique issue as I cannot find much out there that describes what I''m seeing.
