[Rails] Re: ActiveRecord changes Logger formatting
Does anyone have any ideas here??? I no longer have useful Logger
messages. That's very frustrating.

[Rails] Re: Read remote zip
Those are good points.
For now, I whipped up something simple which basically:
begin
`wget #{url}`
`unzip #{localfilename}`
# do stuff with file (FasterCSV)
rescue
ensure
# delete local files
end
I don't like relying on `` but sometimes it's just too easy to pass
up.
My original message was trying to avoid `wget url`
Thanks!

Good point. Ok, a dumb question.

What kind of things go in there? .so libraries like mysql.so? What default location do those usually end up in? Where is a usual place to put them in my home space?

[Rails] Which Oracle connector for AR?
What DB connector do I need to talk to a network accessible Oracle server: 1) with ActiveRecord?, 2) to perform basic SQL. I'm more familiar with what it takes to get MySQL working with AR. Currently I have AR 2.1.1, Ruby 1.8.5. I'll have to ask what Oracle client/server is available.

[Rails] Rails or separate packages, RedHat
So, as I introduced myself to ActiveRecord, I asked our IT department to install activerecord and this hierarchy popped up on the system: /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/ then I was able to do this irb(main):003:0> require 'rubygems' => true irb(main):004:0> require 'activerecord' => true Now I realize FasterCSV, and perhaps migrations would be handy. I'm not building a web application at the moment, rather I'm building a command line api to our DB using ActiveRecord for ORM. However perhaps one day in the future I'll be allowed a rails developed web site So, do I ask the IT department to install Ruby on Rails or continue asking for particular packages? I'd rather just get the whole thing. If so, will an install of "rails" override or interfere with already installed rails libraries? They will only install RedHat 5 managed packages without a huge fight. Other packages, I have to compile and install in my own user space (/home). This is on a RedHat RHEL 5 system (uname = 2.6.18-128.1.1.el5).

[Rails] Help with AR design on a large (~100'sM) partition table
First, I'm a physicist, not a computer scientist. I need to store 65M rows now, with a growth rate of ~21M/year whose entries arrive daily. The purpose of this DB is to store metadata for environmental observations for the ionosphere. Basically it's a glorified file catalogue. I need the usual: fast enough inserts, reasonable recovery, REST like access, etc. I have access to Ruby AR/AS 2.1.1, Ruby 1.8.5 and eventually MySQL 5.1.x. I'm trying to trade some storage space and lack of normalization for simplicity of design and ease of maintenance by me. Basically, I want to partition one very large table. My PK is essentially across 3 columns: filename, md5 checksum, destination. I'd like to partition by year which is discernible by the filename and by obs_time if I can but obs_time is not currently part of the PK. If that happens, then I would have up to 40M rows in a single table though most tables would have a few million; perhaps that is too many; perhaps a table for each half year would work. Currently, I have no foreign keys but I may want them one day. Any help and suggestions would be really appreciated! My schema follows. I have created a simple model off this table and I'm using these decorators: validation, and before_save and after_save to build an inventory summary (in another table not shown). I've tried this on a non-partitioned table so far awaiting the installation of MySQL 5.1.x by our IT department. How do I go about integrating AR with a partitioned table? Can you advise a simple pattern I might follow for such a large but simple relationship? create table `ionofiles` ( -- TODO optimize variable sizes `id` int(15) NOT NULL auto_increment PRIMARY KEY, `file` varchar(100) NOT NULL,-- Any valid filename without the ".~N~" backup extensions. `md5`varchar(100) NOT NULL,-- MD5 Sum `destination`varchar(20) NOT NULL,-- E.g. MIDS, ADIC, AFWA, SWPC, ... `version`varchar(20) default NULL,-- Optional version. `ursi` char(5) default NULL, -- E.g. BC840, WI937. default NULL because we allow any filename. `time_scope` varchar(20) default NULL, -- E.g.

(root, scaled, image, ionogram) `obs_time1` datetime default NULL,-- Start of measurement. Default NULL because we allow -- non data files. `obs_time2` datetime default NULL,-- End of measurement, in the case file represents -- multiple measurements. Default NULL because we allow -- non data files. `extension` varchar(5) default NULL,-- file extension (any case). E.g.

[Rails] Re: Compatible Packages
Thanks Fred! My enormous single table DB crashed this morning and I imagine that "repair table ..." is never going to finish. It's time to get this redesign rolling. Can you point me towards any simple schema but rather large in rows solutions with MySQL/Partition Tables/AR-AS? I need to store 65M rows now with a growth rate of ~20M/year. The new additions are received rather uniformly over the year. I'm going to post a larger more informative version of my new questions in a minute for others to see and perhaps make suggestions.

[Rails] Compatible Packages
I'm interested in using ActiveRecord (AR) to build an API to a glorified file catalogue with ~35 million and counting entries. It's really an MD5sum catalogue with extra information granules about each file to support web services like interaction. Firstly, I'm not a computer scientist; just a hacking physicist with a little OOP experience. In addition to AR for ORM, I'm planning to use MySQL partition tables of type InnoDB. In a private email, David H. said this combination looks compatible: Ruby 1.8.6 or 1.8.7, AR and AS 2.2.2, MySQL 2.7 and MySQL Server 5.1.x. I'm trying not to bother David directly, for this related question. The problem is that our admins will not install Ruby 1.8.6 or AR/AS 2.2.2, instead I'm allowed to have these versions "managed" by the RedHat package manager: Ruby 1.8.5, AR/AS 2.1.1. I plan to take advantage of simple implementations of these built in technologies: transactions, callback macros, validation, association, aggregation, etc Are there any obvious problems with my setup?
