Hi, I have build a conversion script from an old database to a new one (which is designed to work with ROR), and every action converts one table and takes over 5 minutes... When I trigger the actions from my browser, I finally end up with a "Failed to start properly"... So, simple question: How can I do this from the console, that is to say, trigger one of my controller''s

Hi all, I am trying to add an article editing interface to my future webstore, and I am wondering what to use for text formatting. I would like to avoid using HTML, and calibre-bbcode just won''t work (see my last post). Is there some kind of library for live text formatting right in the browser? I would just need bold, italics, size and ul lists... Do you know of a good solution?

Hi all, I am sorry if this question has already been replied here, but I did not manage to find an answer. I am looking for a way to post data to a remote web page. I don''t want to use hidden fields and a submit button, I would just like some ruby code that would post parametres to a web page and store the web page that the remote server sends back. I am not sure that I have been

Hi, I am currently trying to learn RoR and there is something I cannot figure out. I have two models: Article and Category, that are HABTM-linked. Everything works fine if I want to select all articles corresponding to a category, with something like @articles = @category.find(@params[:id]).articles However, I have a ''published'' field in my ''articles''

Hi all, I''ve been spending quite a lot of time trying to install a decent RoR server on my dedicated server (Ubuntu 6.06 LTS), and now, everything works. However, the performances are not really what I had expected... I would like to know what you think about it. Here is my config: 2GHz VIA proc, 1Gb RAM, SATA-II HD. I have apt-got ruby 1.8.4, mysql5 and installed rails 1.1.4 by

I wonder if you can have more than one has_many :through association between 2 models. For example... I have a model Teacher and a model Class Now, 1 Teacher works in many Classes, right?. So I need a join model like class Work < ActiveRecord::Base belongs_to :teacher belongs_to :class end But I also would like to know if a teacher CAN teach a class before I

Hi all! I am trying tu set up RedCloth for user-submitted comments. And here is my problem. The :filter_html option just breaks images :-( For example, if I try in irb: string= "Some textile !agif.gif! and textile again" RedCloth.new(string, [:filter_html, :filter_styles]).to_html(:textile) I get: NoMethodError: You have a nil object when you didn''t expect it! The error

I don't know the details of pls (in the pls.pcr package, I assume), but if you use validation="CV", that says you want to use CV to select the best number of components. Then why would you specify ncomp as well? Andy > From: ryszard.czerminski at pharma.novartis.com > > When I try to use ncomp parameter in pls procedure I get > following error: > > >

Does anyone know if there is a function available which can format any entered number as words? eg: ''1234'' would be ''One Thousand Two Hundred and Thirty Four'' In the past, I would have said this is a tall order, but from what I''ve seen with playing with rails for a short time, I don''t know what to expect. :) Thanks for any help, Damien

How can I get a list of all model classes in the domain of a Rails application (all models, both in "app/models" and in components/somedir/model.rb)? Thanx in advance for your precious help! Edoardo "Dado" Marcora

I have two ideas about it. 1- i) Entering variables in quadratic form is done with the command I (variable ^ 2) - plsr (octane ~ NIR + I (nir ^ 2), ncomp = 10, data = gasTrain, validation = "LOO" You could also use a new variable NIR_sq <- (NIR) ^ 2 ii) To insert a square variable, use syntax I (x ^ 2) - it is very important to insert I before the parentheses. iii) If you want to

The Time::next_week method is supposed to give the time of the start of the next week. But look at this, it cocks up : >> t=Time.parse "Monday October 16th 2006" => Mon Oct 16 00:00:00 BST 2006 >> t.next_week => Mon Oct 23 00:00:00 BST 2006 >> t.next_week.next_week => Tue Oct 24 00:00:00 BST 2006 >> t.next_week.next_week.next_week => Mon Oct 30

Hi, I am currently experimenting on rake freeze_gems and there is something I do not understand. When I freeze_gems my app, it puts Rails in the /vendor/ directory, which works. But what about all other gems I have installed (for example Unicode, sqlite support, mysql support and so on)? The aim of freezing is to be independant of the versions of the ISP, but it seems that the server still

Dear list members; The code given below corresponds to the PCA-NIPALS (principal component analysis) algorithm adapted from the nipals function in the package chemometrics. The reason for using NIPALS instead of SVD is the ability of this algorithm to handle missing values, but that's a different story. I've been trying to find a way to improve (if possible) the efficiency of the code,

Hi All, I was wondering if I could get some comments on my approach to the design of the domain model and database for my rails app. I don''t have much experience in this so I am wondering if I am heading in the right direction. My app is an ecommerce site for my business which is a record label. That might seem straight forward, but the one thing that might be tricky is that

Hopefully simple question: What is the best way to name, and treat factor columns for data that has lots of columns? This is my column list: id pID50 D.1 D.2 D.3 D.4 D.5 , etc. all the way to D.185 I was under the impression from several R examples in pls that if you name your columns like above, you should be able to simply call all the D factors with "D", instead of going in and
