I have been trying to use R to gather some information from parsed log files (as part of examining some performance issues). I parsed the log files and put the data into an SQLite database, and then used RSQLite to load the data into R. The fields of interest are controller, action and total_time: controller and action have string values; total_time has a decimal value. I first did the

I have not devoted time to setting up ROracle since binaries are not available and it seems to require some effort to compile (see http://cran.r-project.org/web/packages/ROracle/index.html). On the other hand, RODBC worked more or less magically once I set up the data sources. What is your success using ROracle and why would it be preferable to RODBC ? -Avram On Thursday, September 11,

I am trying to push some view logic into a helper. The thought is that this is a step towards having the business logic in the helper rather than the view. However, I''m essentially wrapping the checks around an eventual call to date_select(). The problem I''m having is that the application complains that it doesn''t know about date_select(). I''m sure (or

Hi all, For various reasons I need to have foreign keys with not null constraints. Eg: create_table :people do |t| t.column :name, :string t.column :household_id, :integer, :null => false end create_table :households do |t| t.column :name, :string end add_foreign_key_constraint :people, :household_id, :households, :id So the people table has a foreign key into

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

Hi folks. So I''m using mocha on a ruby project, and I really like it. One thing I''ve noticed is that it can be a bit "surprising" when I''m mocking methods that don''t exist on an object, and I think there''s an easyish fix. At the moment, you use sheep = mock() to create a mock sheep. What I''d like to do is something like sheep =

Hi, I am trying to validate a numeric value passed in from a form, which is saved in a MySQL db as decimal(9,2) Now problem is I need to ensure people don''t enter a form value like -. 003. In my validations, I have a validates_numericality_of check being done. Furthermore, in validate method, I have a check using an if statement such as : ((an_object[n].nil? or an_object[n] < 0) and

"Object is the root of Ruby''s class hierarchy. Its methods are available to all classes unless explicitly overridden." Wouldn''t Class class be at the root of the class hierarchy? After all, look at this: 1.9.2p290 :006 > Object.instance_of? Class => true Object is an instance of class, after all we can use one of Class'' instance methods on Object:

There''s a small inconsistency in ActiveRecord''s callback syntax that has tripped me up before. It wouldn''t be a big deal, but it can lead to a silent failure. I''d like to suggest that it either be made consistent or be made to fail loudly. The issue is that to do something before validating, but only when creating, you use `before_validation on: :create`,

In ActiveRecord''s callbacks, methods within a before_create callback are called after the validation, but before the model is created. This was an intentional design decision, but I think it was the wrong one. What do you think? When I think of before_create, I think of before_validation :foo, :on => :create, but, by default, before_create is synonymous with after_validation :foo,

Hi all, I''ve got a form which accepts a "price" field and I''m attempting to validate it and allow some flexibility in the way the user enters it. It''s a numeric field but I want the user to be able to enter dollar signs and commas naturally in the data entry. I''m trying to understand how to use validates_format_of, and I''m not sure what

Hi all My visitors can create party organisator profiles, and I want assign them as the creators (the field creator_id in the organisators table references a member in the members table). To do that I tried it with before_validation: def before_validation creator = Member.find 1 end Sadly, this does not work. The validation validates_presence_of :creator_id Still tells me, that

Hi, I was looking around a bit and couldn''t find any callbacks that executed before before_validation The current problem with using before_validation is that it won''t fire if I''m not using validations with #save(:validate => false) - which makes sense. Before_save won''t suffice because I want these callbacks to fire before validation on the occasions that

Hi, I often find myself using bits of code like this inside ActiveRecord, perhaps it''s useful for others, or others can improve on it: ########### # fix user input before validating it before_validation :sanitize_input # santize input before actual validation is called # this uses the little methods defined below def sanitize_input trim %w(adres postcode woonplaats email naam

I want to remove the leading and training spaces for most of the resources in my rails application For a new POST request, rails does the xml parsing and passes the params hash to the controller. Some of the parameters have leading and/or trailing whitespaces which are causing problems (e.g. new resources being created rather than using the old ones). I don''t want to put the code in all

Hi All, Is there a way to filter / modify the output of a model class before it''s returned to controller/view that''s calling it? Example: I have a field phone_number which I always want to preformat using the number_to_phone() helper.... Any help is appriciated. Thanks! -- Posted via http://www.ruby-forum.com/.
