class Thing < ActiveRecord::Base belongs_to :other_thing end class OtherThing < ActiveResource::Base self.site = ... end The association here works. I can access other_thing from thing with no problems until, as usual, testing. Specifically functionally test the things_controller. The things controller is simple scaffold, however, having the association to an active resource model

Hi all, running into a little problem here. I''ve a list of things with a "New thing" link beneath it. When you click that link, obviously, a new thing shall be created. Now, that works pretty fine for things that don''t have foreign keys, but for things that do it crashes, since there is not yet a thing.other_thing.name available. I suspect you can somewhere in

Hello, In a model I have: has_many :things, :finder_sql => '' select * from other_things '' + '' where id = #{id} '' When I do MyClass.find(:all, :include => :things) I get a weird error: from c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/connection_adapters/abstract_adapter.rb:120:in

I''m new to rspec and looking for way to test a validation I added to a model. The test checks to see that if field1 has a value then field2 must be nil and vice versa. ------------------------------- When I did the rspec_scaffold it generated one test which worked before :each do @valid_attributes = { :field1 = "value for field1" :field2 = "value for

Hi - I have 3 fileds a user can fill out.

I want to do something like this: validates_presence_of Field1, Field2 OR validates_presence_of Field3 So the user can fill out

Hi all, My current project brought forth the snippet below, which modifies in each row of a data frame a certain field depending on another field in the same row. Dealing with data of some 30000 entries this works, but is horribly slow. Can anyone show this newbie how to do this properly (faster ;0)? for (i in 1:nrow(dataframe)){ if

Hi, How can I use a substring match as a condition in a subset command? Sth like this: subset(input, field1=="blah1" & field2=="blah2") # but now with substring match in field2 subset(input, field1=="blah1" & field3 *substringmatch* "blah3") I've tried with gsub, but it won't work: subset(input, field1=="blah1" &

Hello, I wanted to parse some information from a text, where fields are tab separated. When I copy the text into an R session (under emacs) like: mystring <- "field1 field2 field3" the tab character is replaced by a single space! For ex, if I type mystring, I get: "field1 field2 field3" The tabs have disappeared!!! I checked with Python that the text I copied was tab

I want to add virtual fields in a model. table: field1 field2 I want to add field3 which is field1*2 + field2 I know tihs can be achieved in View, but I want it in model. Then I will pass this model to PagerRenderer to paginate. How to achieve this? thanks -- Posted via http://www.ruby-forum.com/.

Hi All, I am a real neophyte with Rails and am struggling with something. I hope you can point me in the right direction. I have a model of an object that class Thing< ActiveRecord::Base attr_accessor :locator_id has_one :otherthing has_one :differentthing end I can create and delete these things until the cows come home. However, trying to change the data and save/update I get a

hello everyone, i'm new to R, so i hope you dont mind a fairly basic R question. we're using R to manipulate the results of SQL queries and create an HTML output. I'm starting with a table that looks essentially like this: Name Field1 Field2 John value1 value2 Jane value3 value4 My table is stored as a dataframe. I'd like to efficiently produce an

Hi, The following [simplified] query works well, however a variation which includes parenthesis seems to fail, in that it returns hits which should be excluded by the NOT term. This is surprising because in this simple case, the parenthesis shouldn''t change the Boolean evaluation ... any pointers? Working Query: field1:value1 AND NOT field2:value2 Failing Query: field1:value1 AND

Hi All, I want to give ranks to elements in a column so I used: total_list$field1.rank <- rank(total_list$field1,ties.method="min") But this gives me the rank in increasing order. How do I get the ranks in decreasing order? I know decreasing = FALSE is not a legal argument here. Thanks.

I believe that I may have found a bug in R. The top code sample gives an error as shown. However, by simply switching which field is initialized first as in the bottom code sample, it works as expected. This gives an error: a <- NULL a[["field1"]] <- 1 a[["field2"]] <- matrix(c(2,1), 1) Error in a[["field2"]] <- matrix(c(2, 1), 1) : more elements

Hello everyone, I've been advised to use merge to extract information from two data.frames with a number of common columns, but I cannot get a grasp on how it sorts the result. With sort=FALSE, I would expect it to give the result back sorted exactly as the input was but it seems it is not always the case, especially when there are repeats in the input. For example: > a =

Say I have a csv file, each row contains several fields, one of them are whether the row is success. In history data, I have all the fields including the result of whether it is success. In future data, I only have fields without the result. For example: history data: Field1 Field2 Field3 Field4 ResultField 1231 CA TRUE 443 TRUE 23231 NC TRUE 123 FALSE

Hello, I''m having trouble using mechanise to post a form. I took a wireshark capture of the form being submitted by firefox and by mechanise. In both there is an HTTP Post and then a ''continuation of non-http traffic'' packet. The obvious difference is that the firefox continuation packet has some http metadata (I don''t know the proper terminology) where the

All, I know there are 3 or 4 search plugins out there. I''m trying to find one that will allow me to search associated fields. My database content is pretty small, so efficiently is not so critical. On the other hand I have ton of :belongs_to type fields, so I need something that works well with the Rails models. Any recommendations? == Example of what I need to work Assume I have a

I''m trying to get a Rico LiveGrid working, and I am a bit stuck on how to accomplish this. I have a page that successfully queries a controller and updates a <div> containing a table. I have two versions of the action; one uses the render_partial to return a rendered version of that table, and the other returns an XML-RPC document, and this is where I hit a snag. The Rico LiveGrid
