For now it is very hacky. The problem is that you have parts of rails which are not multibyte-safe, let alone i18n. Besides, i18n is _quite_a_challenge, I don''t think it can be a "boxed" solution. The amount in which it might be available can vary greatly: 1. Inflector? - proper i18zed inflection would require all stemmer/ linguistics libraries on the planet and then some. You can use pluralization in templates but this will anyway stay English for quite some time. 2. Dates/times - this is a must and shouldn''t be very difficult, and shouldn''t require locales 3. Symmetric object mirroring for languages - now that would be a real threat but I got no idea how this can be humanly handled. 4. Thorough tests for multibyte support (is it only me noticing that TextHelper#truncate inserts an illegal UTF sequence before the dotdotdot?), which will essentially make jcode and $KCODE=''u'' a requirement for running Rails (I think many will riot!) 5. Error messages - now that is kinda ridiculous. What I would love for Rails is that it might provide it''s own string filtering capabilities, so that a special object (of a soecial class?) will be contacted by the framework to format and output messages. Gettext does it but it makes function calls sprinkled all over the place - not neat. What it might be (just a sketch) class Railties::Translation # There was an error in the field bla def error_msg_on_field(field_name, message, relevant_data) end # There was an error in the field "foos" def fieldname(symbol) end #which charset we send? def charset_header_value end #how do we configure the database? def charset_adapter_command end end ...etc. Then it must be possible to implement such an object in your app - and all messages would be passed to it first. When using such a stub it will be left to the developer to determine i18n handling - and developers who know the languages they are working in will be much better off doing it for their language group than making 1 something which will work for everyone but partially. -- Julian "Julik" Tarkhanov

Really the problem is that Ruby itself needs better i18n support before Rails can get it. I''m sure there are various hacks you could make, but things will be much easier if Ruby itself solves a lot of these problems. As far as I know, i18n and l10n (localization) are some of the features on the list for Ruby 2.0, aka Rite. Ryan

What I thought about was actually l10n, not i18n :-) I can say that it is more than possible (necessary and done by everyone) to use Rails with Unicode (and Ruby support for it is actually in some ways better than PHPs - both are nonexistent but...). Of course it is a bit ahead of the cart, but Unicode exists and it has to be done _now_. We have the /u flag on regexen and KCODE - they both work to a certain extent. That''s why it seems strange to me that things such as truncate were not tested for multibyte-safeness. I, on the other hand, was talking about translations and localization - my fault, sorry.

I agree, l10n is the #1 hole I see in Ruby (and by extension, Rails). Most of the complaints, or debate, or what have you against Rails, say from the Java community, or whatever, tends to be around performance and scalability, which as we all know from recent threads is a non-issue (or rather an issue that is not due to it being Ruby or Rails). When folks ask me about how Rails stacks up to say using Java for web apps, this is really the only negative point (and it''s a big one IMHO) I have. I will say that part depends on your perspective and what kind of apps you develop. Tons of web apps are only available in English, and it''s probably a non-issue for many folks. But, if you develop software for a commercial organization that sells software throughout the world, it is a critical feature. It is the only thing that has me hesitate to use it in my day-job projects (we currently use Java). It would be great to see Ruby gain both the localization and internationalization features that Java has, and then for Rails to have features that take advantage of that, similar to how something like JSP 2.0/JSTL, and/or Spring, Struts, etc. provide mechanisms to nicely integrate at least localization features. I would like to help, or offer a solution in this area, instead of just complaining, but the area is also not my forte. I thought there was some project (can''t seem to find link now) called "MLS" or "MSL" or something along those lines that was making efforts here. Also, Ri18n, which may be of interest: http://ri18n.berlios.de/ Also, I haven''t looked at it closely, but the Nitro Ruby framework has something called the LocalizationShader that appears to allow you to do localized string substitution.

Hello,
I asked the community earlier if I should be using the script/generate code
creation stuff - the answer was yes. So I''m trying to use it to create
a
scaffold but it doesn''t seem to work. Below is a transcript of
creating
this application from scratch, finally leading to the error "Before
updating
scaffolding from new DB schema, try creating a table for your model
(Person)".
Is this happening because I have left the golden path by adding def
self.table_name() "contacts.people" end to my model?
Does generate only work for the golden path? After going to extensive
effort to create a database that is golden path compliant I seem to have
ended up on the brown path.
Any help much appreciated in advance. here''s the transcript of what I
did -

Can you run ''rake'' to run all the unit tests ok? Scaffolding needs access to the database, obviously.
Hi Joe - thanks for helping.
If I add scaffold :person to my controller as follows, then everything seems
to work okay.
class PersonController < ApplicationController
model :person
scaffold :person
end
I need to modify the code though so it''s not really practical to work
with
the default scaffold, I''d rather generate the code and modify that to
my
needs.
Andrew

Do you have the database all set up? Can you run ''rake'' to
run all
the unit tests ok?
Scaffolding needs access to the database, obviously.

But it''s odd that it would work when putting :scaffold in the controller, but not being able to generate the code.

Hi Joe, Rake falls over and says: 1) Error: test_truth(PersonTest): ActiveRecord::StatementInvalid: ERROR: relation "people" does not exist : DELETE FROM people But I don''t have a relation "people" - I have a relation "contacts.people" which I why I specified table_name() in my model. Andrew

I think we''ll just let >it rest as a limitation."That seems to imply that code generation is out of the question for any database that doesn''t follow the golden path. That''s a pity when the community recently put forward some strong arguments for using Rails code generation. So I must live with it. So the question is, what do I do now? How does a newbie build a non golden-path application without having generated code to dig around in and try to understand and extend? What''s the Best Practice/accepted way of moving forward? What do the Rails pros do when they can''t generate code using the script/generate stuff? Cheers and thanks in advance Andrew

It might be helpful to work through one or two of the tutorials. With that you''ll have a simple and "golden path" application sitting on your hard drive to look at for reference. You can use that as a launching point to see what to change to fit your situation. -- doug-jGAhs73c5XxeoWH0uzbU5w@public.gmane.org

This will do a "SET search_path TO contacts" in your postgresql database. This way you don''t need to mention the schema name to rails with table_name(), as postgresql will find the table by itself by following the search_path (obviously, if you have two tables called people in different schemas, this won''t work). Does anybody know where this is documented? I found it when browsing the code for the postgresql adapter... regards, Bas
