Hello, I have a set of templates creating some files for me. All data on my site is encoded using iso-8859-1. Now I want to save the text in the file using utf-8. I have tried using iconv, but whenever I have the require "iconv" statement in my model, there is some error happening in the model and the model doesn''t get loaded (not sure how to debug that).

Hi, I have good this cool challenge from my boss on developing a very simple cms-like system to publish articles within. The caveat is that he wants to have multi-lingual content. At first I thought RoR would be perfect for the assignment but right now I''m not so sure. My first attempt involved creating a table for each model/languagde like this: articles_en articles_dk articles_de

Hello, I''ve spent a couple of hours now searching for (what I thought) was pretty straightforward. I''m using mongrel together with RoR and need to execute a .rb file located in my public folder (cgi style). But mongrel just can''t do that out-of-the-box - or am I missing something? I really don''t get how I''m supposed to configure mongrel for this

For a project I''m working on I''m hoping to be able to have both discussion and announce-only e-mail lists. Does anybody have any recommendations about good existing mailing list apps that could be integrated with a rails app? Does anybody have any experience using ActionMailer as the basis for a mass mailer? Does it perform well enough to make it feasible? Thanks! -- Dan

Hi All, How do I specify a composite primary key for a table in ActiveRecord? For example the table Recipe which has the primary key [cookie id, version number] where cookie id is also a foreign key referencing Cookie.

Have been looking into using rails but am finding the "Composite Primary Keys are Bad" thing a tad disturbing (to put it mildly). I have been working with RDBMS systems for over fifteen years and this is the first time I have herd the idea questioned. I have cone across using surrogate keys which mirror the composite key for performance reasons in VERY big databases but I have never

I''ve been trying to use Rails on a database where the biggest datawarehouse-style table doesn''t have a primary key. It really doesn''t make sense and just adds extra unnecessary space. I do have, however, a column that I normally use to search on (IP) that returns many rows. The table also references several other tables through rails-friendly foreign keys. Simple AR

Hi, As I understand, composite primary keys aren''t supported in ActiveRecord yet. May I ask if there are plans for this feature? Better yet, if this feature is under development, how''s the progress going? I''m not trying to use legacy databases. I tend to think that using multiple integer column id''s (composite primary key) are often natural way to

Hi I am really sorry for this probably quite simple question. I am new to R, and I am running a pipeline that has already been made. All I have to do is give the paths for different folders, where the pipeline can find the files with my data. But every time I try to run the pipeline it returns with the message, that it cannot find the file. And I really don't know why. I have found the path

I know ActiveRecord doesn''t support composite primary keys, but I need to use one, and I need it ASAP. I don''t need any composite foreign keys, luckily; what I have is a table that stores old versions of rows in another table, so the composite key is an id + date stamp. Would someone tell me a hack I can use to support this? -- View this message in context:

Hello, Is it true that Rails doesn''t support composite primary keys? I have a legacy system and was pondering adding a new interface to it. This whole Rails thing (and yes, Ruby too) seems pretty interesting but I''d feel ashamed of myself adding an additional column called ''id'' when there''s already a perfectly good composite key. Assuming the rumors

hello, what is the strategy you use for composite primary keys ? I saw the solution proposed by Graham Glass ( ticket 3201) using a set_composite_key..., but it seems it is not in AR ....(why ?) thanks for feedback arnaud
