Hi I''d like to know how to have ActiveResource generate a URL for the /teams/1/edit type of resource. I''ve got custom_methods.rb and have used Team.find(1).get(:edit) This generates http://localhost:xxxx/teams/1/edit.xml But all I get returned is a hash of the attributes (in this case of team 1), rather than an object of team 1. In other words the

Hi, I have a very sime app. I need to create as many records in the db as the selected checkboxes (named :isselected) in the view. Here is the code snippet from the controller: isselectedhash = params[:isselected] for mod in isselectedhash.keys @issue = Issue.new(params[:issue]) @issue.state = ''NEW'' @issue.mod_id = isselectedhash[mod] # this gets

I have a problem displaying images when using attachment_fu. When I try to display the image, only about 40k appears in the browser, and with some images even that much is not visible (just garbage when I view source). I can display images smaller than 40k correctly. I''m storing the images in the database (mysql) and haven''t tried storing in the file system to see if that works

I have: class Post < ActiveRecord::Base has_many :comments do def published find( :all, :conditions => {:published => true} ) end end end When in my controller I do Post.find(:first).comments.published.paginate :page => params[:page] I get an error undefined method `paginate'' for []:Array Is will_paginate supposed to

Has anyone hacked Builder::XmlMarkup to dasherize underscore tags by default? I know I can use tag!, but I''d like to find a way for it to translate underscores to dashes automatically. In other words: xml.department_manager do "fred end #=> <department-manager>fred</department-manager> I tried hacking Builder::XmlBase.method_missing but got myself all twisted up!

Hi All! This is not a problem in general but i''ve just missed the point. If my application has a global state, which i have to use both throughout ActionController and ActiveView, then, where to place that state? E.g. if I do this: class ApplicationController < ActionController::Base protected def authenticated? !user.nil? end end then I can''t use that from any

See the blog post at http://blog.lonestarsoftware.net/2007/03/09/active_resources-010-released/ Reading through the rails blogosphere last week, I read a post (which I can not find again) that suggested a completely different approach to AJAX use in rails apps. The idea was to create a Javascript proxy to the ActiveRecord models and allow AR operations to be called from the client. I see this

Hi, I''m trying to serve the iPhone a video file from my controller using send_file. However, it appears as thought the iPhone requires byte- range request support and rails doesn''t seem to support this. If I give the iPhone a url that points to an actual file (i.e. it''s served by my webserver nginx, instead of rails) it downloads and plays it fine. Here is the proof

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, I am having a small problem concernig how to access local variables in before_create. I am not sure how to really form this question but here goes: I am wondering why this works def before_create self.last_logged_in = Time.now self.created = Time.now end but this doesn''t def before_create @last_logged_in = Time.now @created = Time.now end The latter fails

We have a product where our customer is "allowed" to make minor changes to the .rhtml views. Obviously, this can be an issue when updating the software, as changes need to be merged in. Also, sometimes the customer wants to back out there change but no longer has the original file. SOOO.... I''d like to tell them - if you want to change a .rhtml file - just copy it to

All, I''ve upgraded to 2.0.2, and I can''t get my login screen (the first POST request in the application) to work. When I post this form, I see the "InvalidAuthenticityToken" error. I have protect_from_forgery :secret => ''my_secret'' set in application.rb and I am using an active_record session store based on this line in environment.rb:

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

I have a unit test which fails using Rails 1.2RC2, because a method marked by the before_create filter is firing twice when my ActiveRecord is saved. Is a before_create filter supposed to cause multiple invocations? We have assumed it is called once, and only once, when the object is created, in our code (but we unit tested it to make certain). This is one of three issues I have with my unit

I am trying the Restful-Authentication (latest version, downloaded today) and upon running the generator, doing the migration, prepping the test system and putting the resources in routes.rb I get a Rspec test failure: ''SessionsController logins and redirects'' FAILED expected not nil, got nil routes.rb has: map.resources :users map.resources :sessions nothing else was

I have the following models: User, Registration, Event. User has_many Registration, Event has_many Registration, and Registration belongs_to User and Registration. So far, so good. There''s a registration deadline on a Event though, a few days before the Event occurs. So, I have this: class Registration < AR def before_create errors.add_to_base("Registration deadline has

Hi, Can anyone spot why the below doesn''t work? * I have a "created_by" column in my create table in the dB * I have a "before_create" line, which definitely gets called * I tried a few different ways to set the "created_by" attribute in the model but it doesn''t seem to work, i.e. doesn''t appear in the database

if I have the following in my routes.rb: map.resources :product_categories it provides urls such as: /product_categories /product_categories/1 /product_categories/1;edit etc. and uses the ProductCategories controller. how can I keep the same controller (and model) but set up the resources so that I can have any abitrary url point to the existing controller, much like specifying the controller

Hi all, I would first like to introduce myself to the Ruby on Rails (RoR) community and to say that I hope to begin to build some relationships with other RoR developers. I''m a long time Java programmer (5+ years). Java was my first experience with Object Oriented Programming (OOP). Before Java I developed using many other languages including C, Pascal, Fortran, BASIC, Visual Basic,

I know that usually when people say ''i think i found a bug in rails/ruby'' they''ve done something dumb. I''m wondering if this is the case here, but this does seem like a genuine rails bug to me. In my user model i have a few different before_create callbacks. In one of them, if it happens to return false (just because the last statement in it evaluated to
