Hello all, I am curious about what tools you guys use to make your databases. I know David uses CocoaMySQL. Are there other tools for other platforms and for other databases? I''m not very good with the SQL language, so I would like being able to do all my database setup with an easy-to-use tool (defining tables, fields, primary keys, foreign keys, indexes, etc.) Big kisses, Vincent.

For a really long time, I''ve been using DBDesigner from FabForce.net. For those of your who''ve never used it, its a freeware visual entity-relationship diagram tool, which allows you to make database designs visually instead of in SQL DDL. You can then use it to generate the SQL to make your databse design into reality, or even run a "synchronize" to make any

Did I see some code posted here that would create a graphical representation of a database relationships using the graphviz utilities? -- Posted via http://www.ruby-forum.com/.

For users without an internet connection we are thinking about converting a rather large site to a DVD. As dynamic solutions with databases seem hard (see another thread) we are also considering a static html version. The site is clearly convertible to a static version, I can make sure that all search functions are turned off. Can the conversion itself optimized with Rails? Do you know solutions

I seem to have trouble getting DBD4 to create ActiveRecord-compatible DDL statements. I have a database with a series of 1:n relationships which should be easy to model. But, depending on the relationship type I use, when I connect them in the ERD it either: 1) starts cascading foreign keys like an avalanche, or 2) fails to add ''contraint fk_xxx foreign key (yyy) references

I know you get a lot of questions like this, but I couldn''t find one which answers exactly what I''m after. I''m reasonably new to rails, and I''m having a bit of trouble with when to use belongs_to. On the rails wiki ( http://wiki.rubyonrails.org/rails/pages/belongs_to), it says "In general, the Foo model belongs_to :bar if the foo table has a bar_id foreign

Can anyone recommend a database modelling tool for the Mac? I''m building a new Rails app and want an interface to draw out the database''s entity relationship diagram, setup foreign keys and then output DDL at the end to MySQL. I''ve previously used DBDesigner, CASE Studio and some pricier enterprise software on Windows, but can''t find anything suitable for my

is there anyway that scaffold would read the database and I don''t have to specify any of the columns? it is really frustraiting specially when you''ve got a lotta cols and tables! I''d like to use rails for an enterprise app but not a toy app like all those apps in tutorials -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~

Chris, Finally got time to fully play with your suggestions. Had to re-code a bit of stuff but the concept works - just like a bought one :~). Many thanks for the solution, Kind Regards, Eric.

Hi everyone, Just wanted to tell you a little story. We''ve been enthusiastic puppet users since about a year ago here at the Geographic Institute of the University of Zürich. But we won''t use the zpool type ever again. Its just not worth it. Here''s what happened: . one of our servers lost knowledge about one of its zfs pools . puppet didn''t find the pool

Dear R users, Is it reasonable to transform data (measurements of plant height) to the power of 1/4? I?ve used boxcox(response~A*B) and lambda was close to 0.25. Regards, Christoph

Hi all, I have thousands of strings like these ones: "1159_1; YP_177963; PPE FAMILY PROTEIN" "1100_13; SECRETED L-ALANINE DEHYDROGENASE ALD CAA15575" "1141_24; gi;2894249;emb;CAA17111.1; PROBABLE ISOCITRATE DEHYDROGENASE" and various others..

Hello List, I have a production machine with very low ram (Xen Virtual Server) that runs mysql and lighty->pound->mongrel (2 instances). About once a day, one of the mongrels just locks up, leaving that in its log files: *** glibc detected *** /usr/bin/ruby: free(): invalid next size (fast): 0x0a744780 *** That process (mongrel) will stay locked, not answer any connections anymore and

Hello, I'm Carla, an italian student, I'm looking for a package to transform non normal data to normality. I tried to use Box Cox, but it's not ok.

Hi Folks, I''m sure tons of people are gonna ruin a whole drawer of their best panties over this one. Rick Olson worked on the mongrel_upload_progress gem, documentation and examples and has almost everything you need to do progress tracked file uploads using just Mongrel to handle the upload. This means that Rails (or any other framework) isn''t blocked while the upload

Hi list, I have tried to reach Bradley (author of mongrel_cluster) by mail, but have not gotten a response. So I''ll try trough this channel: I have ''developed''[1] a small extension to mongrel_cluster that allows selective restart of any one listener in a configuration that contains more than one listener by using a command like mongrel_rails

Hi everybody, Im a newbie, but i hope someone can help me in this work... Ill try to explain what i need to do in the best way, but my english is not good...

It seems that a recent code cleanup broke --user and --group switch in the trunk. Mongrel essentially ignores these commands. This applies to everyone who has installed gem install mongrel --source=http://mongrel.rubyforge.org/releases/ recently. I have attached a patch to revert to some old working code. best regards, kaspar -------------- next part -------------- An embedded and
