Hello everyone! Ive been on rails for the last month or so and really enjoyed this framework. However its very hard to find documentation on how to do things right! For example every beginner after a while realizes that having similar CRUD actions in every controller and views for them is not DRY at all! Few days ago I found http://dereksivers.com/rails-shared-controller.html I quite like his

Hi, I''m having some problem with getting collection_select to return the current value when editing a record. According to everything I''ve seen, there was an issue but it''s been fixed, but I can''t figure out why it isn''t returning the current value as a selected option. I''ve checked the table structures, and both the call_driver.product_line_id

Where can I find more information about the new syntax on these: <%- model_class = @product.class -%> <h1><%=t ''.title'', :default => t(''helpers.titles.new'', :model => model_class.model_name.human, :default => "New #{model_class.model_name.human}") %></h1> <%= render :partial =>

I''m having a real problem with nil objects in a view I''m playing with. if I type ... <%= debug lesson.lesson_register.attendees %> I get the following displayed in the browser .... - !ruby/object:Attendee attributes: enrollee_id: "25" created_at: 2009-08-27 15:10:41 updated_at: 2009-08-27 15:10:41 id: "1" attended: f

I was looking at my controller code and the edit/create/update/new for each are practically identical. So first I DRY''d the four methods in each controller to just one and then I decided to write a single macro for all my controllers. This is the macro: def self.edit_action_for(model, options = {}) model_class = Object.const_get(model) define_method(:edit) do

I''m trying to build a page similar to a delicious page that is a listing of your bookmarks in this format: 1. Querying serialized data in ActiveRecord<http://www.karmiccoding.com/articles/2005/11/29/querying-serialized-data-in-activerecord> Hack to search serialized fields to rails <http://del.icio.us/djsodom/rails> ... and 4 other

If you've 'rediscovered the web' with Firefox (http://getfirefox.com), you might find this tip handy. Suppose you want to search the (local) R documentation for information about the lme function. Wouldn't it be nice to just type into the browser address bar: r lme and have the search performed? Here's how (on Windows): Click on this link:

First, thanks to everyone who replied to my pluralization question from before! Today I''m confused by associations. I''ve set up a bunch of associations in my models to describe these relationships: - each user can have many bookmarks and tags - each bookmark can have many users and tags - each tag can have many bookmarks and users (Part of what is confusing is that I can

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I found this to be quite interesting not sure if there are any plans for implementing it. The problem In a regular Multi Page Interface (MPI) website, each page has a unique URL. These URLs can be used to bookmark your location, and the browsing history is just a list of those URLs in the order you visit them. An AJAX application however has a

Hi all, I have two types of models which I''m not sure how to model (or if it''s even feasible) with ActiveRecord. Let me know if you''ve got any good ideas. 1) For those of you who are familliar with del.icio.us, you probably know that you can bookmark a site, and add your own tags to it. Each person has their own tags for a site, even though multiple people can

I''d like to delete some records before saving them. I ran this experiment: before_save :prune_lab_datas def prune_lab_datas lab_datas.each do |lab_data| lab_data.destroy end raise lab_datas.to_yaml end But nothing seems to be deleted in the hash: --- - &id001 !ruby/object:LabData attributes: created_at: 2010-03-21 22:16:06 unit_id: "3"

I am trying to use wice grid plugin and I have run into problem. The problem is when I have nested paths as follows: Hardware :has_many installed_softwares Software :has_many installed_softwares installed_softwares belongs_to both when I view individual hardware, I have a link "Installed Software" -> hardware_installed_softwares when I use wicegrid to view installed software and

Hi Suppose one has a db to track bookmarks for multiple users. Let''s assume that there are ten''s of thousands of users, and that an average user may have 100 bookmarks. (Assume here that no two bookmarks are the same.) Is it a common practice to have a bookmark table for ALL users, thereby producing a table that has on order one million rows. Or, is it better to somehow group

If you use Notes 5 with wine, you probably have the problem, that the bookmarks frame doesn't open when you click on Favourites or other folders on the left side. Solution: Create a Memo in Notes Go to the Body field and select Create/Hotspot/Button In the lower half, select Script and paste in this code Sub Click(Source As Button) Dim db As New

This is pretty much the same as last time around, if you recall. Thanks to Wilson for converting to the new form. I''ve added a few lines. Basically, it iterates over your model associations and does two things. - First, just try to call the association. Usually fixes speeling erors or other such silliness. - Second, try to find a record with an :include on the association. This

Hi all, I'd like to know how well Speex handles multiple input streams. More specifically, if i have 4 streams that are playing at "the same time", how well does the CODEC handle switching from one stream to the next to process the audio. The reason i ask is this....My project up until now uses the MELP CODEC which didn't specifically have the ability to handle multiple

Hi Think this is probably straightforward, but I don''t know enough about rails to work it out, so was wondering if anyone can help I keep on running into this error when I''m deploying my app: "FastCGI: server ".../public_html/public/dispatch.fcgi" stderr: ../config/../app/views/items/_side_share.rhtml:8: warning: Object#id will be deprecated; use

Hi Everyone, I want to create a button in my app which can be placed on browser bookmarks toolbar. And for any website when i click on that bookmark, it will open a layered window (like popup) which will have page title and domain name of that page And also it will have some input fields. It will be a form from my application. And when i will submit that window will close down and update

I would like to have my computer at home and my computer at work to share the same bookmarks. My idea was to have each of the computers sync with a server's bookmark file. If the client has a newer file than the server it would upload it, if the client has an older file it would download it. I already have the authentication keys set up and want to do it over ssh. Would this be one way to
