In response to a few private e-mails, here a summary of using Delphi, R-DCOM and R 2.2.0 1) As Earl Glynn noted ( http://finzi.psych.upenn.edu/R/Rhelp02a/archive/50705.html ), there were a few paths specific to my installation in http://www.menne-biomed.de/download/RDComDelphi.zip leading to path errors on compilation. Hopefully, this has been corrected in the new zip file. 2) Always check if

Each post has a single category, which I''m filling a drop down list by using this: #view <p><label for="post_type_id">Category</label><br /> <%= collection_select(:id, :type_id, Type.find(:all), :id, :category) %> </p> In my Post model I have a field called "type_id" which is to be filled by the id in the Type table upon

Dear listmates, I've recently moved a server from RHEL5 to CentOS 5.3 after it was decided not to renew the subscripton. Everything works beautifully except for Bugzilla, which throws MySQL errors. For example, the sanitycheck.cgi page says: # # # Bugzilla ? Sanity Check * Home * | New * | Search * | * | Reports * * | My Votes * | Preferences

Have you read the books by Cleveland? His experiments show that most people do better estimating things and comparing things on a linear scale rather than looking at angles and areas (also see http://biostat.mc.vanderbilt.edu/twiki/pub/Main/StatGraphCourse/graphsco urse.pdf) With a dot chart you can set the axis to go from 0 to the total of all groups (see the example I sent before, it could

Hello, I would like to report 2 very minor typos: 1. help file for package:base function:function The last sentence of the "Technical details" section reads: "This is not normally user-visible, but it indicated when functions are printed." Either "is" is missing ("but it is indicated") or "it" should be replaced by "is" ("but

Hi All, I have some strange problem which appears only on heroku hosting 2.3.5 default stack (not on my local computer) I have some models.

Hi all, I''m having some trouble with a has_many association on a table using the single table inheritance model that I''m hoping someone can help me with. The schema for the table is: CREATE TABLE `comments` ( `id` int(11) NOT NULL auto_increment, `user_id` int(11) default NULL, `type` varchar(20) NOT NULL default '''', `type_id` int(11) NOT NULL default

I''ve been using the login generator ''out of the box'' for simple authentication, and its been working fine. Now I want to extend it by simply adding ''type_id'' field which links to my ''user_types'' table, but I''m hitting: #<ActionController::SessionRestoreError: Session contained objects where the class definition

Hello all, I''m developing an application which allows users to browse items for sale... Using the url localhost:3000/browse/by_type/2 (2 is the id of the category they are in) Displays the information I want, however localhost:3000/browse/by_type/ will display an error page (becuase the id param is not set) in my by_type.rhtml view, how to i check to see if the param is set? and

Hi, I''m a newbie on both Ruby and Ruby on Rails, and I''m struggling with my first app. I have a table with a column called "employee_id" which is a foreing key associating it with the "employees" table. I have populated both tables. When I run "ruby script/generate scaffold <model name> <controller>" it generates a web page with all

Hey Rails People, I''m doing my first Rails app and I''m having a newbie problem with the count method.... Mysql::Error: #42S02Unknown table ''jobs_sectors'' in where clause: SELECT COUNT(*) FROM jobs WHERE (jobs_sectors.sector_id = 1 ) Extracted source (around line #4): 1: <div class="sectors"> 2: <ul> 3: <% for sector in @sectors

I want to be able to find items according to various params - category_id, member_id, type_id, rating, etc. What I have now is something like: if(@params[''category_id'']) @items=Item.find(:all, :conditions=>["category_id=?", @params[''category_id'']) elsif(@params[''category_id''] and @params[''member_id''])

Is this even possible? I''ve got a ruby expression stored in a database, it''s the code to run a plugin since I was having trouble passing variables stored in the database. When I try to call the code, it either outputs it as text, or doesn''t display it at all. It''s supposed to generate an image and display it. right now the code is stored in the database as:

I am very confused about where to put the belongs_to and the has_one (and other relationship identifiers). I have read the RDoc and the agile book many times about this and I think i still see it backwards. Let me outline my app so you have an understanding... I have 2 tables: Schools { id, school_name, address_id } and Addresses { street1, street2, city, state, zip, country } *** this

With the help of the Rails Recipes have got a self-referential HABTM relationship working, but I''m really struggling with getting a new entry from a form accepted. i should say here that the form is also submitting info for the join table too. So in my model I have: class Type < ActiveRecord::Base has_and_belongs_to_many :subtypes, :class_name => ''Type'',

Hi, what are your thoughts on where and how to store static information like for example a countries list? I can''t decide whether I should store it as a table called Countries in the database or just create a non active record model that just lists the countries in a hard-coded array in the model file. Is one better than the other? -- Posted via http://www.ruby-forum.com/.
