Is anyone using migrations with a SQL Server database who might be able to lend me a hand? I''ve used migrations with MySql in the past and haven''t run into any issues so forgive When I run rake migrate nothing is actually getting updated in my database. I created a migration using ./script/generate migration AddFooTable and updated the migration to look as follows: class

Hi all, when I execute the command "rake db:schema:dump" i get this error in the db/schema.rb file. ____________________________________________________ # Could not dump table "region" because of following ActiveRecord::StatementInvalid # OCIError: ORA-00918: column ambiguously defined: SELECT lower(i.index_name) as index_name, i.uniqueness, lowe r(c.column_name) as

I am sure this is doable but I can''t find a specific example and my brain is frazzled. Basically, I am doing a whole load of in-place editing and need methods to support the updates. Here is what I am doing now: def set_blog_website faq = Faq.find(params[:id]) faq.blog_website = params[:value] faq.save! @faq = faq do_ret end Surely there is a generic way I can

How does one do a SELECT MAX query in rails? I''ve searched and searched and tried lots of things with no luck. I want to implement "SELECT MAX(column_name) from table_name and have it return the maximum value from column_name. I just need to get that one value, not the whole object... Thanks for any ideas...

development.log contains quite a few SELECTS on system tables like COLUMNS. Wouldn''t it be more efficient to cache this info? I''m also wondering about strings like "[4;35;1m". What''s their purpose and is it possible to get rid of them? They look like screen coordinates and makes no sense in a text file. Christer Processing ReportController#create (for

Dear R users, do you know an easy way (other than star plot) of making several points laying one over another visible? Is it any simple way of increasing such "multipoint" symbols - or shifting their positions randomly to make several points in one place visible?

Hi! Uhm are attributes just something like additional members of a class, other than those that come from the names of columns in the table? I''ve got images table, which has ''name'' column.

Does anyone have a good working e-mail validator? or even some regexp to make the validates_format_of work right... that would be awesome. Also, maybe an online tutorial for regexp. i''ve always been afraid of it but i think it''s time to face the fears. thanks! -- Posted via http://www.ruby-forum.com/.

Hi, after some experience with Rails on MySQL databases I gave it a try on one of our larger Oracle database. I was facing a problem when Rails tried to detect the columns for a model/table. The appropriate statement ran about 1 min which led to a timeout. Our Oracle guru told me to analyze the SYSTEM schema. After that hadn''t helped, he said the only remaining chance is to use a

I''m just looking into how to connect to Oracle using Rails. I''ve got everything connecting and working as it should. I have a Users table in Oracle: create_table "users", :force => true do |t| t.column "username", :string t.column "created_on", :datetime t.column "email", :string t.column "note", :text

I want to build an application that lets me (the end user accessing a web page) design a simple list with columns and add records. E.g., if the end user says I want a table that has a list of songs, he can create a list (title, date, artist, label) and then make another list of, e.g., books on his bookshelf with the necessary columns (title, author, pub_date, shelf). The end user

Hi! What is the easiest way to restrict access to some part of the page? In php i just put .htaccess and .htpasswd files in /admin folder and it worked.

Hi! Previously i had ruby 1.8.2 (One-Click Ruby Installer) installed, but the rdoc and plugindoc didn''t work, so i decided to install ruby 1.8.4. I had uninstalled ruby 1.8.2 (uninstaller deleted the whole ruby folder with radrails and everything, just great) and installed One-Click Ruby Installer 1.8.4-16 preview3. Then installed rails, rmagick, radrails, created docs for trunk

Hi, Sometime when I attach a dataset, R gives me the following message/warning:"The following object(s) are masked from package:datasets: column_name". Does anyone know what it means? Since it seems that the dataset was attached and I could manipulate the data from the dataset without problems, I am wondering what was R trying to tell me. Thanks, Tom [[alternative HTML version

Hello, I'm trying to duplicate what's an easy process in RapidMiner. In RM, we can simply use two operators: subgroup iteration attribute value selection (Can use a regex for the attrribute name.) I can do this in R with a lot of code and manual steps. It would be really nice to find a more automated way. My data looks like this group group_height group_weight height

Hi, I think the columns and table in migration should be able to have an optional "display_name" set manually. Something like: create_table :people, {display_name => "Personne"} do |t| t.column :first_name :string, :display_name => "Prénom". end Let me explain my point of view: Rails is a framework made to write programs in English. You see it when you

Now, if I put 10 of them in one form, fill them all out and submit, I get

Say I am building a blogging platform, and I want to allow users to be able to add an avatar without leaving the page, when they''re writing a post. I need the avatar information to be included in the form for the post. So for example, after a user adds a new avatar while writing a new blog post, it would be available to be selected as the avatar to be used for that post. What is
