Hi, Has anyone come across a Ruby mathematical expression parser, capable of parsing out token, replacing them with values then executing the mathematical formula? Nothing too heavy, A * (44/12) * ... etc. where A is can be replaced with a value. In Java there are serveral, like JEP, but I''d prefer it we could get a Ruby one now we have moved over to Rails, otherwise we will have to

Has anyone come across this problem... I created some Ruby files in Textmate on my Mac - and everything works fine. However, when I run those files on a Windows machine I get e.g. compile error ./script/../config/../app/views/station/consumption/new.rhtml:2: Invalid char `\002'' in expression ./script/../config/../app/views/station/consumption/new.rhtml:4: parse error, unexpected

Having jotted down some models, with some inheritence I tried to run some unit tests. After waiting for rake test_units to run I got a rake of errors (if you''ll forgive the play on words). The errors were to do with unknown tables in the tear down stage. The unknown tables corresponded to sub-types where single table inheritence was used. In other words, these tables *shouldn''t*

Hi, I realise that Windows is a poor platform and that Webrick is a development, not production, server. However, we have started seeing this crop up when perfectly simple page to page links are invoked... [2006-03-28 08:32:21] ERROR Errno::ECONNABORTED: Software caused connection abort /usr/lib/ruby/1.8/webrick/httpresponse.rb:324:in `write''

As is often the case when I tackle a new platform/language, I get the big picture very quickly (because frameworks are frameworks are frameworks) but its the nitty-gritty of the language that bogs me down... So I have some similar methods on a few of my model classes that I wanted to push into a helper. Now I reckoned that the Ruby way was to create a module and mix it in with include. However, I

I want to make use of a form_remote_tag to submit a form asynchronously. Easy done. However, we also want to add an observe_form tag to check for some value changes while the form is being entered. The observe_form tag needs a dom id to work on but I can''t see how to enter an html option for the dom id of the form on the form_remote_tag. Any ideas? Here is the form tag so far...

Hi, As a long time Java/J2EE exponent I wanted to give Rails a fair crack of the whip and after we evaluated it for several weeks I have to say I like it. The installation process for the base system/framework is straightforward on the two platforms we''ve tried (Windows and Mac OS X). However, the charting components available, relying on ImageMagick or GraphicsMagick seem less clear

Hi all, I talked to Aaron briefly about this at RailsConf, but I just wanted to bring this up here before I start working on it in case anyone objects. I will be looking into moving the "Plural version of the model detected, using singularized version. Override with --force-plural." warning and the associated flag into the model generators. Currently this is only in the resource (and

what is the proper way to make this work? --force-plural doesn''t seem to change the results. this only seems to happen when you choose words that the plural and singular is the same word. script/generate scaffold equipment name:string description:text warning Plural version of the model detected, using singularized version. Override with --force-plural. results in the following

Hi guys, I have a situation here. I have my project set to no pluralization due to legacy tables in environment.rb. Now, I have some new tables which I''m starting to pluralize. When I do a generate a scaffold to this new table: script/generate scaffold my_tables table it seems to work out fine for certain sections like http://mysite.com/railsapp/new (which also inserts properly to

Hey all, I need to launce a rather lengthy process from a small Rails application. It''s the sort of thing (sending out an email newsletter) that would need to be launched from a browser window, but the browser doesn''t need to stick around to see it through. I played around with Thread.new, but I think, based on limited testing, that the threads need to complete before the view

Hi, I found out that Rad Rails names could be properly made plural, such as "country" = "countries" not "countrys". . I have a database that contained one table named "countrys". I pluralized the name by adding an "s" as "countrys".I ran the Rad Rails generator and created a "controller" that was named "country

although data is a plural of datum but Rails is insisting that it is... as usage of "meta" to refer to ancilliary information is fairly common, I''m sure others are going to run into it Thomas

Hi, I recently made a model called ''news''. I realize that it''s plural and was gonna cause some problems, but I got the routing all down fine with: map.resources :news, :singular => :news_article everything works fine except the EDIT method. it gives me this error: You have a nil object when you didn''t expect it! The error occurred while evaluating

Hi, I'm trying to set up a Samba 4.1.16 file server for our (Samba 4) domain. But for some reason I can't seem to be able to get it to work. Even worse, I have run out of ideas on how to debug this. I've been tampering with this for quite some time now, but I've come to realize I can't figure this out on my own. Can someone give me some pointers on where to look in order

I just got a new server with a Dell MD-1000 SAS unit and 6-750 gigabyte drives which are now initializing in RAID 10 which will give me just about 2 terabytes. I vaguely recall reading that fdisk wasn't suitable for partitioning and wonder if I shouldn't be using partd instead. I am also wondering if I should use lvm or just mkfs to create the filesystem. Anyone have suggestions before I

We switched our mail server over from mbox to maildir a few months ago and couldn't be happier - the performance under normal load is incredible. However we now have a problem with backup.. Typically we would run tar on the mail server, sending its output to another server via ssh.. Like this: tar cfp - /home | gzip | ssh other.server (cd /backups && tar xfp -).. I have tried

I have a Cable ''modem'' that has a problem that many of these devices is bound to have. I was wondering what other lartc user thought about this and if DSL has simular problems. Cable, being Asymetrical, is able to upload at a given rate and hopefully has a buffer, in the modem, of some kind. When I nc(netcat) to a UDP echo, or discard, server I get about 10Mbps out on my

Hi, R people. I'm shy reporting this, as a bug in this area sounds very unlikely. Did I make my tests wrongly? I'm still flaky at all this. Let me dare nevertheless, who knows, just in case... Please don't kill me! :-) Not so long ago, I wrote to this list: > (For now, [the library code] works only for me when I do _not_ use `-l > MY/OWN/LIBDIR' at `R CMD INSTALL'

Dear Help: I am trying to follow Professor Bates' recommendation, quoted by Professor Crawley in The R Book, p629, to determine whether I should model data using the 'plain old' lm function or the mixed model function lmer by using the syntax anova(lmModel,lmerModel). Apparently I've not understood the recommendation or the proper likelihood ratio test in question (or both) for I
