Hi Everyone, I''m totally brand new to RoR. I''m really starting to love coding more now that I''ve found RoR. I have what might be a dumb question, but I''m curious to know this. Is it normal to get this result: In the Beginning Rails 4 book I''m following this step: irb(main):097:0> article.location = "Toronto, ON" Here''s

I''m using Restful Authentication, and the code to create a user is pretty straight forward - there is a before_save action and a before_create action: before_save :encrypt_password before_create :make_activation_code But for some reason when I try to create a user programmatically in the controller like this: User.new(:email =>

I have modified scaffolding code slightly to get three edit actions and three update actions. The requirement: to allow users to edit attributes for the same model from seperate forms instead of one form, while using the given scaffolding code and performing model validations. I am using restful_authentication with the login email password validations defined. class users_controller

Hello everyone, just wondering if anyone can help me with a migrations question here. Using: rails 2.0.2 ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin] mysql 5.0.45 Platform: windows xp The problem: ---------- I created a migration that is designed to add a column named "deleted_at" (timestamp) and then remove a column named "is_deleted" (boolean). The idea is to

Using the acts_as_paranoid plugin with rails 1.1.4 (model also uses acts_as_threaded and acts_as_taggable) and getting some unexplainable behavior. The following tests: assert_equal Conv.count, num assert_equal Conv.count_with_deleted, CONVS_TOTAL Produce the following SQL: SQL (0.000000) SELECT count(*) AS count_all FROM convs WHERE (( convs.deleted_at IS NULL OR convs.deleted_at

Hi... Isn''t there a proper way or hack/workaround for the following? * For the example with unfortunate disabilities.. look below,,, Usage of has_* (associationmethods) do {def with_deleted AccociatedModel#with_scope} {Paranoid''s#find_with_deleted}... The has_one associations give me a nil object when invoking it with Model.association_OBJECT.with_deleted. Has_many does like

I''m no good at SQL and I have a question that will hopefully be fairly easy to answer. I''m using acts_as_paranoid which instead of deleting a record adds a deleted_at column with the datetime the row was deleted. I want to have a find_by_sql filter out any row where deleted_at is not null. I have (at least the relevant parts): #a couple working filters here. filters <<

Trying to get an otherwise working app (in Rails 2.0.2) up to speed with Rails 2.1.0 and Ruby 1.8.7, I have some broken code I can''t seem to fix: module Pathmaker def self.append_features( base ) base.before_save do |model| model.path = model.name.downcase. gsub( /\ and\ /, ''-'' ). gsub( /\ on\ /, ''-'' ).

Hello, I have a freeze field in a table (that I can''t change).

Hi, guys I have a puzzle about default_scope. Suppose I have two model: class User < ActiveRecord::Base has_many :blogs default_scope where(deleted_at: nil) end class Blog < ActiveRecord::Base belongs_to :user end I want to produce sqlselect blogs.* from blogs inner join users on users.id = blogs.user_id and users.deleted_at is null And the code Blog.joins(:user), which I think

1. Users_Controller CRUD expects param[:id] to create User instance. With Orders_Controller, I'd like to retrieve a list of users who have ordered. I know Orders_Controller expects param[:id] to be for creating Order instance. So does this mean if I want to retrieve a list of users who have ordered, I should create a method called 'get_orders' in Users_Controller? 2. Can

Can anyone clarify something for me? I''ve been having a hard time with write_attribute. If I do (for instance in a callback): write_attribute(:user, user) Is obj.user_id set automatically too? And viceversa, if I do: write_attribute(:user_id, user.id) Does that set obj.user for me? Doesn''t seem like it''s doing that for me. Anyone understands exactly what

Hi, For some reason, this harmless block of code in my application controller def index @wide = true end is causing this hideous error. I have read the error means that the error is raised when attribute has a name reserved by ActiveRecord. Does that mean that none of my models can have columns named "toggle"? Here is the error and framework trace:

I have a real problem with the acts_as_paranoid plugin. The aliasing of find and so the nested scope does not seem to work at all, when combining it with similar plugins. The description: I made a copy of ''acts_as_paranoid'' in the plugin directory, renamed it to ''acts_as_very_new''(just a nonsense plugin for testing), and simplified the code (original code

Hi there, I have a file upload form on my page that is for images.

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)

Hi there, I''m writing a little application that parses an image file and extracts the camera settings from the file (the EXIF data) and saves all the fields to the database. The idea is that after awhile people will be able to search based on camera make, model, lens settings, etc... and all the pictures that meet those requirements will be displayed. The picture is stored on the file

When I run [code] script/generate authenticated user --include-activation [/ code] it seems to work at first, but then it reports: " The name ''SessionsHelper'' is either already used in your application or reserved by Ruby on Rails.
