Hi, we are running some Debian-linux boxes and want to run a Feger-weatherstation under wine to get the weatherdata directly on the same server as our semi-public weather web (http//81.33.7.96). I installed wine (version is now 0.0.20040713/1.3) under Debian sarge and then the Feger software. My windows partition was an empty FAT32 partition. I cannot get the COM port working and I do not know

Hi Everyone, I am a graduate student who will be using R to do my analysis. I need to do a spatial analysis, and the first step is to calculate the geographic distance between my study sites. I am hoping to use earth.dist because it allows for multiple pairwise distances to be calculated at one time. I have done a sample calculation, and I seem to have a problem between the steps of using

Can acts_as_ferret search only one of the inherit models in the hierarchy of STI models? Say you have Contents, with types articles and comments. I know that you do Contents.find_by_contents, but can you also create indexed for Comment and Articles? Thanks for you help Miguel -- Posted via http://www.ruby-forum.com/.

Hi! I am looking for a solution for the following problem: Some of my models share some attributes and also was in need for some extra features, so I created a class "RecordWithFeatures": ----------------------------------------------------------------- class RecordWithFeatures < ActiveRecord::Base # @Override def self.descends_from_active_record? superclass ==

Here''s the text of a quick note I''ve added to the Inheritance wiki page. I''m actually proposing that it would be a good idea to drop automatic single table inheritance and force people to declare it explicitly. There are two reasons for this: 1. Implicitly doing it unnecessarially limits your use of inheritance where you really need it: in your object-oriented

Here''s the setup (working off Rails 1.1.4): Class Project belongs_to :employee Class Employee < Person has_many :projects When I try to paginate(:employees, :include => :projects) I get the error "Association named ''projects'' was not found; perhaps you misspelled it?" I can :include other models that the Person class has_many or habtm of, and if I

I''m considering serializing attributes of extended classes to one column instead of using STI. Each of the extended classes will have associated views to render the UI based on the serialized params. The references to the associated views will be stored in the model. I don''t need to query the params. I''d like to hear about any pitfalls and experiences of others who may

I''ve written an extension to AR to allow hiding of attributes(aka columns) in AR objects. If there''s interest in it I''ll roll it up into a plugin. Here''s an example: (straight from Agile Web Dev) # The table create table people ( id int not null auto_increment, type varchar(20) not null, /* common attributes */ name varchar(100) not null, email

Hi, It seems that setting a with_scope on the parent class doesn''t do anything MyClass.with_scope(:find=>{:conditions=> ["somecol = ?", ''val'']}) do @ext_pages, @ext_rows = paginate :my_extended_class, { :per_page => 13 } end # this doesn''t generate WHERE somecol=''val'' In order for scope to work you have to call

I''m trying to understand how to do the following, but am finding myself stuck. I have three main tables; here are the first two: CREATE TABLE reference_items ( "id" integer primary key, "type" varchar(20), "title" varchar(255), "year" year(4) ); CREATE TABLE "agents" ( "id" integer primary key, "type"

All, I had been working on a project that was using STI to a very high degree. It also was using a HABTM table that had a couple extra attributes. It seems that with 1.1 push_with_attributes is deprecated and I am having a bit of trouble moving things to using has_many :through The original schema I had worked like this : create_table "nodes" do |t| t.column "title",

Hi all, I need to model simple typed polymorphic relations: ''John'' [''works_for''] ''Bill'' ''John'' [''speaks_for''] ''Microsoft'' ''Microsoft'' [''hold_shares_of''] ''Apple'' I''m having a hard time combining : - S.T.I.

OK. Here''s another one on STI (thanks for the help of all of you with my previous STI question, and I promise to update the wiki with the info). I''m having a prob with validation with the sub-classes. It''s a bit long-winded to explain, but I''ll post all the logs and code if there''s no obvious answers. Basically, however, I have validation on the

Hi, This does not seem to be covered anywhere. Since base class extends ActiveRecord with a table that has fields for all heirs, would that mean that any heir class can access any of those attributes, including ones that belong to other heirs? Or I am missing something? -- Posted via http://www.ruby-forum.com/.

http://kylemaxwell.com/articles/2006/02/06/fun-with-single-table-inheritance I wrote an article about how to use rails and single table inheritance to implement multi-page web forms with incremental validation. I''m looking for any feedback, and I hope that the development technique is useful. I just ran through the tutorial myself, and everything is working for me on my

Hello ~ I have run into an issue with some of my objects not behaving as I expect. Basically I am using STI on my Users table and have several types of users. BaseUser --UserType1 < BaseUser --UserType2 < BaseUser etc.... Recently when I create a UserType object and save it to the database it ignores the validation rules for the parent class BaseUser. Furthermore the after_validation

Folks, I''m fairly new to Rails, and I''ve Googled around for an answer to this question with no luck... Consider a little blog application that has uses single-table inheritance for the handful of different content types via a Content base class and subclasses like FooContent and BarContent. That part all works well for me. Now consider the view that presents actions to the

I suspect this is a bug. Or a limitation. Problem: ---------------- When you include a STI class in a ''find'' : @results = Result.find :all, :include => :event , you are forced to specify the fk and the class name : belongs_to :event , :class_name => "Event", :foreign_key => "event_id" . Full code: ----------- class Event <
