I''ve got some of this working but other parts are ellusive. I have CREATE TABLE `bags` ( `id` int(11) NOT NULL auto_increment, `name` varchar(255) NOT NULL default '''', PRIMARY KEY (`id`) CREATE TABLE `packages` ( `id` int(255) NOT NULL auto_increment, `name` varchar(255) NOT NULL default '''', PRIMARY KEY (`id`) CREATE TABLE

after playing with the DB interaction I''m moving on to doing some file IO. but I''m completly lost as to where to put the code and how to call it. I''m trying to get a list of files in a directory and it''s not obvious to me how to do this in Rails via a controller method. so ruby code is Dir.entries("testdir").last and html code is <%=

I''ve demoed my rails app and now have to move it to a MSSQL DB. the big problem I''m running into is the table name conventions I have to use. I have to use names like tbl_Transfer & tbl_User. In my tests on the console, I am trying myvar = tbl_Transfer.find_by_sql("select top 1 * from tbl_Transfer") NameError: undefined local variable or method

I''ve rewritten my kickstart cgi in rails with DB acces to the host list and the testing is perfect. I can send the macaddress in the HTTPrequest Header, rails looks up the macaddr in the machine db and spits back out a kickstart file for the machine.. however in real world usage what I get is a request for http://server//kickstarts/kickme which rails fails with 192.168.20.176 - -

I usually use the cross-correlation between the speaker signal and the mic signal. It works pretty well. The problem is the you need enough data in order to get a good S/N. I compute the cross-correlation between 1.5 second data of each signals. In this way the application detection of any anomalies is quite slow. I am looking for something faster, but I fear it will be something very application

1) Everytime a participant speaks there is a echo for a short duration (maybe a word or two) but as the participant continues to speak without a any break the echo is 95% cancelled (i.e there is a feeble echo still present if observed very carefully). 2) The moment the participant stops / pauses speaking and start talking again, scenario 1 is repeated as if the echo state has been re-initialized

Yes. I guessed that too, however I am not sure why it keeps repeating every time the user stops / pauses and starts speaking again in a single session. I am using a laptop with standalone speakers. For echo cancellation to work one has to make sure that the ref and echo buffers are synchronized. I guess this is the most common problem. -Elston -----Original Message----- From: Anton A.

First: this is my first post on this list so any suggestions, let me know. I recently had to make the move from SMBFS to CIFS when I upgraded from Fedora 4 to 5. Changing settings in my /etc/fstab was easy and no errors come up but now I'm having an issue very similar to post I found on your list that got no response back in April: http://lists.samba.org/archive/samba/2006-April/119813.html

Hi, when I define a db column to be non-nullable or of length 20 or as numeric, I would expect rails to validate that, but that doesn''t seem to be the case. Any idea why that is? The metadata is accessible, at least in the mysql case. I am using rails 1.0 with mysql 5. Cheers, Mariano

I have orders, order_items, and products. I want to collate several orders so that I can get a SUM of quantities ordered for each product etc. Can I say something like (the below gives an error on :sum, and ignores :group) OrderItem.find(:all, :sum => ''quantity'', :group => ''product_id'', :include => [:order, :product]) I want to get back a

I''m trying to pull ou the ''name'' field for each of my associated rows and pass it as a string of names. I''m missing something obvious here but I thought @bag.packages.name.join(", ") would work. do I have to loop through @bag.packages? that seems like the long way. thanks -zac -- Posted via http://www.ruby-forum.com/.

I created a controller called reports, for which I didn''t have any model or tables. I wanted to use a menu/layout structure similar to all my other models/controllers and added a layout named reports which then gives me the menu/layout structure but is also now part of all my reports. That isn''t gonna work so I renamed reports.rhtml to reports_forms.rhtml (still inside my

Hello, I am a complete newbie with Ruby and Rails. I am working on learning it by writing a project I was going to write in PHP using Rails. I am having a difficult time finding clear information on how I would do this. I need to take a date out of a table in my database and given another day calculate the next 28 day anniversery of the original date. This is used to calculate a delivery

In my rails application, certain computers were having huge problems. There were certain pages that were exceptionally slow, even to the point of timing out. Other computers did not have a problem. I finally found that Firefox was the difference. When using Firefox on those computers it works fine. The slow pages were typically posting a form with a couple hundred fields. This behavior was

Hi guru''s out there, Im happilly coding my first rails app, and all goes well. I find myself manually coding in a particular field all the time (company_id), that relates the contact to a company.
