similar to: How do I test a unique index?

Here''s something that''s a snap to do in desktop database management systems (like Paradox or Access) but I haven''t figured out how to do it in RoR, and can''t seem to find any examples by googling, etc. My overall goal is to create a temporary space in which to create and process a single new record (representating a payment transaction), and when I''m

I''ve added a drop-down list of first and last names of borrowers to a form. How do I sort them by LastName, FirstName in the drop-down? I''m using code based on the cookbook example: <select name="borrower[borrower_id]"> <% @borrowers.each do |borrower| %> <option value="<%= borrower.id %>"> <%= borrower.FirstName <<

my models borrower ----- has_many :loans loan ----- belongs_to :borrower my loans _controller def new @borrower = Borrower.find(params[:borrower_id]) logger.debug '' @borrower.id'' logger.debug @borrower.id @loan = Loan.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @loan } end

Hi all, I have a shopping application I am testing, and one of the models is an Order model, within which a credit card number is encrypted and stored in the db (mysql) as a BLOB field. When trying to run my unit tests, I cannot get my model fixtures to load the encrypted data. If, in my dynamic fixture (YAML) file, I could have access to my app''s models, the problem would be trivial..

Hello, I'm interested in correcting for and measuring unobserved heterogeneity ("missing variables") using R. In particular, I'm searching for a simple way to measure the amount of unobserved heterogeneity remaining in a series of increasingly complex models (adding additional variables to each new model) on the same data. I have a static database of 400,000 or

Agile Web Development with Rails doesn''t seem to have NULL in the index [or my eyes have failed me again], and web searching turns up lots of SQL statements containing NOT NULL. I have a table of loans, and I want to record when something was loaned and returned. The loan date can''t be null, or there''d be no entry in the table. The return date must be something

I am new to ruby/rails and am having a problem with validates_length_of. It seems to work fine on a varchar field, but when I try it on a char field the extra characters are silently truncated and the message appears that the record was successfully updated. How can I get my app to produce my error message instead? I''ve tried various variations, but here''s one of my tries:

I would like to compare and contrast code and effects from various different tutorials and sample applications. Can I run, say, a mongrel server from more than one app location? I know I can''t do that if they''re both using port 3000 (I tried), but is it possible to configure some apps to use a different port? Where would I do that? Most of the apps are using mysql databases.

Hi All I found survfit function was very slow for a large dataset and I am looking for an alternative way to quickly get the predicted survival probabilities. My historical data set is a pool of loans with monthly observed default status for 24 months. I would like to fit the proportional hazard model with time varying covariate such as unemployment rates and time constant variables at loan
