Hi guys, Given a page that retrieves data from a 3rd party API, how would you then go about associating additional info in the application''s database with that record? Specifically, the page displays info on a product, and I''d like to store and display locally created reviews for that product. To display the product I''m using a route of the form /product/

So I would like to be able to update a record without having to load the edit page. Lets use checking out a book as an example. From the front page of my application I would like to be able to have a form field where I can enter a record id and select one of a couple of check boxes and then hit submit which will update the associated record with the action selected by the check box (check out,

I have just upgraded an app to rails 3 following the railscast screencast. I have installed a blank application inside the app to be upgraded with: rails new . I have replaced all the the main files. When I run rake routes I get no output. routes.rb: App::Application.routes.draw do resources :products end (ie, just the default file with an example uncommented) I have tried a number of

Within a rails app I''ve got a special url (/profile) that I''m mapping to the user controller to allow a user to view and edit their profile. I made the following entries into my route file so that the "get" for profile will route me to the profile action in the user controller and the "post" for profile will route to the update_profile action in the user

For the initial data step, assuming a data frame named stress already exists, and using base R, you can start with something like this: barcodes.to.delete <- c('16187DD4015', '16187DD6002', {complete the comma-delimited vector of barcodes you don't want} ) yield <- subset(stress, !(barcode %in% barcodes.to.delete) ) yield <- subset(yield , !(field %in%

Hi guys! ;) If you set "routes.rb" as: map.resources :pocoyo You have RESTful rails routes facilites. Ok, let''s focus on these two maps: "http://domain.com/pocoyo" [GET] is mapped to "pocoyo" controller and "index" action. "http://domain.com/pocoyo" [POST] is mapped to "pocoyo" controller and "create"

You might get better answers if you 1 - break this down into separate issues 2 - tell us what you want to achieve in words rather than SAS, we all read English but few of us speak SAS 3 - post in plain text not HTML as HTML mangles your post On 29/09/2017 13:47, Andrew Harmon wrote: > Hello all, > > My statistical analysis training up until this point has been entirely done > in

Hello all, My statistical analysis training up until this point has been entirely done in SAS.

Hello Rubyists, I need to generate barcodes (in UPC and codabar symbologies) and would like to know if anyone has done this with Ruby. From what I can tell, it would be possible to use the gnu-barcode [1] or barcodewriter [2] to generate a PostScript, then through RMagick (via GhostScript) take the file and create a GIF/JPG. These will really only be used for web display (to be printed

I''m trying to stub(!) the Kernel.` (backquote) method and I''m having confusing (to me) results.

I wish to second this approach to learning R. I tried for several years to translate other stat programs or provide parallel analyses with R. This dabbling-in-R approach did not work . When a transferred to a research unit that could ill afford commercial software, I devoted my entire time to doing everything in R. This was a difficult learning process, but I eventually became proficient

I will offer an opinion, with which others may fairly take issue. If you are coming from SAS and wish to learn R, you should forget about SAS entirely; it is ancient and convoluted. But more to the point, as others have already suggested, you will only confuse and hamstring yourself trying to convert the programming paradigms of one language into another. Better to consider the **tasks** you wish
