(This message was originally written on StackOverflow -- the formatting is much prettier there -- http://stackoverflow.com/questions/1283046/problem-with-setter-override-on-activerecord) This is not exactly a question, it''s rather a report on how I solved an issue with write_attribute when the attribute is an object, on Rails'' Active Record. I hope this can be useful to others

Hi all, Suppose I have a vector Fruits <- c('Apple','Orange','Pear','Banana','Mango') I want to print the statement "The fruits in the basket are: Apple, Orange, Pear, Banana, Mango" If I do: print(paste('The fruits in the basket are:',Fruits)) The output is: [1] "The fruits in the basket are: Apple" "The fruits in

All, I''m finally doing my first real form in Rails - the model object that I''m entering information for has 8 validations so far. If I type in good values for all the fields but one, I get the pretty validation, and the nice field highlighting, but all of the fields are cleared, forcing me to retype all of that info. That is a big drag. Is there a standard way to get the

Hi, I am having trouble using before_create when I have an specialized setter method: before_save :set_campaign_start #----------------------------------------------------------------------- ------- def set_campaign_start self.campaign_start = Time.now end # We want the date to always start at midnight

Would really appreciate it if someone could tell me why this is happening: I override ssn method of AR class so I can encrypt/decrypt to/from the db: class Person < ActiveRecord::Base def ssn=(value) write_attribute(:borrower_ssn, Crypto.encrypt(self.encryption_key, value)) write_attribute(:borrower_ssn_final_four, value[5,4]) end def ssn # this begin - rescue can be

There are datatypes that need to be converted back and forth from a string representation: they need to be parsed both coming from the database, and coming from elsewhere like views. Dates are an example, and I recently needed to implement a more forgiving converter for decimal numbers. So we have here at least two flows of execution, for example: post.date = "22-jan-2007"

Hi there fellow R-users, Does anyone know if there exists a package for associated rules data mining (market basket analysis) in R. I have tried searching CRAN but with no luck.

Could someone explain this? #config/initializers/ar_attributes.rb module ActiveRecord module AttributeMethods alias_method :ar_read_attribute, :read_attribute def read_attribute(attr_name) p "read_override" ar_read_attribute(attr_name) end alias_method :ar_write_attribute, :write_attribute def write_attribute(attr_name, value)

Dear friends - I hope you will accept a naive question on lm: R version 3.4.1, Windows 10 I have 204 "baskets" of three types corresponding to factor F, each of size from 2 to 33 containing measurements, and need to know if the standard deviation on the measurements in each basket,sdd, is different across types, F. Plotting the observed sdd versus the sizes from 2 to 33, called

I have a model where I want to change the display for a single attribute such that if the value is an integer, it displays with no decimal point (e.g. "1"), but if it is non-integer, it displays with a decimal point (e.g. "1.25"). The easiest way to do this seems to be if I could override the to_string method for my_model.my_attribute.to_s. Is there a way to do this? Or

Hey.. So I have a model that has a lot of number fields. Each of these go through a process when read in and read out to add/remove commas (between every three numbers) to make them more readable. The getter I currently have is like this: def sale_price Listing.insert_commas(read_attribte (:sale_price)) end and the setter is: def sale_price=(price) write_attribute(:saleprice,

I'm just curious if any one else has noticed this. I've bought hard drives from both Walmart and Best Buy. If I can wait, I order them from newegg.com. I'm beginning to think that the staff at both Walmart and Best Buy, somewhere along the supply line must dribble the drives like basket balls. The reason I say that is all the drives I have bought from those two places fail within a few
