How do I specify which option should be initially selected when using the collection_select command? I''ve tried: collection_select(:selectionfilter, :producer_id, Producer.find(:all), :id, :name, {:include_blank => true, :selected_value => @initial_selection}) However it doesn''t return the desired results (the option with the value of @initial_selection selected).

Someone use kaminari for pagination? I''m doing some tests but I don''t know why I have an undefined method page. Here is my simple test: describe "GET index" do it "assigns all fire_preventions as @fire_preventions" do FirePrevention.stub(:search) { [mock_fire_prevention] } get :index assigns(:fire_preventions).should

I''m having a problem with belongs_to and has_and_belongs_to_many. Here''s a brief summary of the models involved: class Member < ActiveRecord::Base set_primary_key ''member_id'' has_and_belongs_to_many :projects, :join_table => ''projects__members'' has_many :projects, :foreign_key => ''created_by'' end class

Hi I have been struggling to get a foreign key in a list map to a readable value in a lookup table I have a list of projects and each project has a project_manager. Project.rb class Project < ActiveRecord::Base has_one :project_manager, :class_name => "Users", :foreign_key => "manager_id" end The association above sais that a project_manager is in

Hi, I cannot seem to create associations like this: class Project < ActiveRecord::Base belongs_to :manager, :class_name => ''User'', :foreign_key => ''manager'' belongs_to :liaison, :class_name => ''User'', :foreign_key => ''liaison'' end p = Project.new p.manager => 1 trying to retrieve associated objects

I have three tables, Invoices, Projects, and Managers. Each manager has many projects. Each project has many invoices. When displaying a list of the invoices, I am using: Invoice.find(:all, :include => [:project]) Since the list shows information from the project table. (For example, a table showing Invoice Date, Project Name). However, I''d also like to show the manager name.

Folks, I''m fairly new to Rails, and I''ve Googled around for an answer to this question with no luck... Consider a little blog application that has uses single-table inheritance for the handful of different content types via a Content base class and subclasses like FooContent and BarContent. That part all works well for me. Now consider the view that presents actions to the

Hi, I''m quite new to Rails and have a problem with the use of AWS. The Problem is, that I have a class which provides some basic attributes and some subclasses of this with more specific attributes. I want to send objects of those classes through SOAP by a remote client, but if I specify just the base class in the method signature of my API definition the generated WSDL file will

ActiveSupport provides a method Object.subclasses_of, to give the subclasses of a given class. However, it ignores any subclass within a module, so : class A end class B < A end Object.subclasses_of(A) # returns [B] module C class D < A end end Object.subclasses_of(A) # returns [B], even though C::D is also a subclass of A class E < C::D end Object.subclasses_of(A) # returns

Hi all, I''m thinking about making the switch to RoR for one of my projects. I''m trying to figure out if ActiveRecord can handle one of my inheritance hierarchies before I do. I have a more detailed question up on stackoverflow: http://snurl.com/kg89x Is this possible? Thoughts?

I''m trying out inherited_resources and so far so good. However, one problem I''ve run into is that it''s very difficult to customize inherited_resource behaviour in subclasses. Looking through the source I see it uses things like undef_method and class_attribute. For example, if I have the following controllers: class ItemsController inherit_resources actions :new,

This should not affect current code but it may help people who deal with LLVM instructions. Up till now one could create an llvm::Instruction (and subclasses) using the following constructor: Instruction(const Type *Ty, unsigned iType, const std::string &Name ="", Instruction *InsertBefore = 0); If InsertBefore was specified the instruction was added to the basic block

Right, the methods package is not attached by default when running R with Rscript. We should probably remove that special case, as it mostly just leads to confusion, but that won't happen immediately. For now, the S4_extends() should probably throw an error when the methods namespace is not loaded. And the check should be changed to directly check whether R_MethodsNamespace has been set to

Not sure why R_has_methods_attached() exists. Maybe Martin could shed some light on that. On Mon, Apr 18, 2016 at 11:50 PM, Kirill M?ller <kirill.mueller at ivt.baug.ethz.ch> wrote: > Thanks for looking into it, your approach sounds good to me. See also > R_has_methods_attached() >

I have several modules that I store in rails_root/lib and that are used by my controllers. I''m having a problem accessing AR objects from inside a class that is a subclass. I keep getting a NameError when trying to do something like Foo.find(), where Foo is an AR object. uninitialized constant OpenTransact::Gateway::Request::CreditCardCharge::PaymentAccount (NameError) For some reason

That just means the ELF writer doesn't know yet how to deal with the target-specific data. It needs taught how to map them onto relocations and such. Do you really need to subclass MCTargetExpr? That's ordinarily only for operands that aren't representable via the normal MC stuff (for example, the ARM movw/movt relocations). You should be able represent normal symbol operands w/o

I have a STI class tree. I want to set some default values (calculated values so I can''t set it in the database as defaults) on every created instance regardless of what subclass is actually instantiated. So I figured adding a after_create callback in the top class in the hierarchy should do the trick. It seems it doesn''t get called :( Code: class SuperClass <

Dear Developers, A lot has been changed in the R12.0 with respect to behavior of "environment" subclasses. Many thanks for that. One small irregularity, though; new.env does not allow the parent to be from S4 subclass. > setClass("myenv", contains="environment") [1] "myenv" > new.env(parent=new("myenv")) Error in new.env(parent =
