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

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

Hello all, I have a syntax question. How does one refer to a field brought in via a has_one/belongs_to relationship in a form helper? Basically, I have two models: class Resource < ActiveRecord::Base has_one :other_thing end class OtherThing < ActiveRecord::Base belongs_to :resource end It has the normal id-resource_id foreign key relationship. OtherThing has two fields, plus the

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

I am having problems with a validation, the full model code is below. The validate routine is attempting to see if another record with the same artist_name, title, & catalogue_no exists in the products table. If so, it should throw an error. This is the validation code: def validate if Product.find(:all, :conditions => ["artist_name = ?, title = ?, catalogue_no = ?",

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

Hi, I''ve got an interesting one here :) I have a form with three fields : serial_number initial surname now, if serial_number is entered, it must be between 1 and 64000.

You

Hi folks, I have a question regarding validates_uniqueness_of, and similar before-filter-like events attempting to guarantee some DB state prior to modification. >From my reading of ActiveRecord, validate_uniqueness_of appears to cause a SELECT on the underlying table attempting to ensure that a record with ID(s) specified in the validates_uniqueness_of statement is not already present, prior

I apologize if this is a very simple question; I''ve searched the forums, wiki, Google, and Agile Web Development with Rails to no avail. Is there a way to put conditional validation in the model? For instance, if I want to limit items a user can add unless the user is an admin? My current code is: validates_uniqueness_of :user_id, :scope => ''event_id'',
