  • has_many :through default values

    - by David Lyod
    I have a need to design a system to track users memberships to groups with varying roles (currently three). class Group < ActiveRecord::Base has_many :memberships has_many :users, :through => :memberships end class Role < ActiveRecord::Base has_many :memberships has_many :users, :through => :memberships end class Membership < ActiveRecord::Base belongs_to :user belongs_to :role belongs_to :group end class User < ActiveRecord::Base has_many :memberships has_many :groups, :through => :memberships end Ideally what I want is to simply set @group.users << @user and have the membership have the correct role. I can use :conditions to select data that has been manually inserted as such : :conditions => ["memberships.grouprole_id= ? ", Grouprole.find_by_name('user')] But when creating the membership to the group the grouprole_id is not being set. Is there a way to do this as at present I have a somewhat repetitive piece of code for each user role in my Group model.

  • for TimeWithZone object, how to change the zone part only?

    - by leomayleomay
    I have a table Coupon with a field expired_at, which is of datetime type, and before I save the record, I want to change the zone part of the field according to the user's choice. Say, c = Coupon.new c.expired_at = DateTime.now c.expired_at_timezone = "Arizona" c.save! and in the coupon.rb class Coupon << ActiveRecord::Base def before_save # change the zone part here, leave the date and time part alone end end What I'm saying is if the admin want the coupon expired at 2014-07-01 10:00 am, Arizona time, the expired_at stored in the db should be like this: Tue, 01 Jul 2014 10:00:00 MST -07:00 is there any way I can modify the zone part only and leave the date and time part alone? Thanks

  • Ruby: totalling amounts

    - by Michael
    I have a Donation.rb model with an amount column that takes an integer. I want to sum all the individual donations together and show the total on the home page. In the home_controller, I'm doing @donations = Donation.all and then in the view I do <% sum = 0 %> <% @donations.each do |donation| %> <%= sum += donation.amount if donation.amount? %> <% end %> The problem is that this is printing the running sum each time a new donation is added to it. I just want the total sum at the end after they've all been added together.

  • retrieving data from memcache

    - by Adnan
    Hello, I am starting to learn the benefits of memcache, and would like to implement it on my project. I have understood most of it, such as how data can be retrieved by a key and so on. Now I get it that I can put a post with all of its details in memcache and call the key POST:123, that is OK, and I can do it for each post. But how to deal with the case when I query the table posts to get the list of all posts with their titles. Can this be done with memcache, or should this always be queried from the table?

  • ActiveRecord bug? Or am I getting it wrong? (validates_presence_of if)

    - by Dmitriy Likhten
    Ok: User attr_accessible :name, :email, :email_confirmation validates_presence_of :email_confirmation if :email_changed? What happens in the following situation: u = User.find 1 u.name = 'Fonzi' u.name_changed? # => true u.email_changed? # => false u.valid? # => false : email_confirmation is required Basically, if I change if to unless the validates works as expected, won't validate if the email has not changed, will validate if the email changed. I thought the IF indicates "run this validation if the following function returns true. Seems to work backwards!? Am I just getting it wrong?

  • How to turn off SSL on heroku

    - by rockyroadster555
    I'm redirecting a domain to Heroku using a cname. Currently Its working but is giving me an ssl error. Is there a way to turn off ssl on heroku? Heres the SSL Error This is probably not the site you are looking for! You attempted to reach app.grewpr.com, but instead you actually reached a server i identifying itself as *.herokuapp.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of app.grewpr.com. You should not proceed, especially if you have never seen this warning before for this site. When I try to go to http://pure-chamber-1979.herokuapp.com/ it automatically redirects me to the ssl version. Is there a way to turn this off?

  • Should I denormalize a has_many has_many?

    - by Cameron
    I have this: class User < ActiveRecord::Base has_many :serials has_many :sites, :through => :series end class Serial < ActiveRecord::Base belongs_to :user belongs_to :site has_many :episodes end class Site < ActiveRecord::Base has_many :serials has_many :users, :through => :serials end class Episode < ActiveRecord::Base belongs_to :serial end I would like to do some operations on User.serials.episodes but I know this would mean all sorts of clever tricks. I could in theory just put all the episode data into serial (denormalize) and then group_by Site when needed. If I have a lot of episodes that I need to query on would this be a bad idea? thanks

  • How do I pass object values with render :action => 'new'

    - by PlanetMaster
    Hi, In an app I have the following: def new @property = Property.new(:country_id => 1, :user_id => current_user.id, :status_id => 'draft') end def create @property = Property.new(params[:property]) if @property.save flash[:success] = t('The_property_is_successfully_created') redirect_to myimmonatie_url else flash.now[:error]=t("The_property_could_not_be_created") render :action => 'new' end end When an error accors, the line render :action = 'new' gets executed, but the my form gives an error: user blank country blank These cannot be blank (defined in model), meaning this code: @property = Property.new(:country_id => 1, :user_id => current_user.id, :status_id => 'draft') is not executed anymore. What is the reason and solution? Thanks!

  • How do you pass self to class_eval in ruby?

    - by klochner
    I'm working on a metaprogramming task, where I'm trying to use a single method to define a polymorphic association in the calling class, while also defining the association in the target class. I need to pass in the name of the calling class to get the association right. Here's a snippet that should get the idea across: class SomeClass < ActiveRecord::Base has_many :join_models, :dependent=:destroy end class JoinModel < ActiveRecord::Base belongs_to :some_class belongs_to :entity, :polymorphic=true end module Foo module ClassMethods def acts_as_entity has_many :join_models, :as=:entity, :dependent=:destroy has_many :some_classes, :through=:join_models klass = self.name.tableize SomeClass.class_eval "has_many :#{klass}, :through=:join_models" end end end I'd like to eliminate the klass= line, but don't know how else to pass a reference to self from the calling class into class_eval. any suggestions?

  • auto_complete plugin error: Couldn't find Question with ID=auto_complete_for_...

    - by bgadoci
    I have successfully set up this plugin before so I am curious as to what I am doing wrong here. I have built the ability for users to add tags to questions. I am not using tagging plugin here but that shouldn't matter for this. With respect to the auto complete, I am trying to have the form located in the /views/questions/show.html.erb file access the Tags table and display entries in the tags.tags_name column. When I begin to type in the field I get the following error message: Processing QuestionsController#show (for 127.0.0.1 at 2010-05-31 15:22:20) [GET] Parameters: {"tag"=>{"tag_name"=>"a"}, "id"=>"auto_complete_for_tag_tag_name"} Question Load (0.1ms) SELECT * FROM "questions" WHERE ("questions"."id" = 0) ActiveRecord::RecordNotFound (Couldn't find Question with ID=auto_complete_for_tag_tag_name): app/controllers/application_controller.rb:15:in `init_data' For some reason I am actually passing the field name as the Question.id. The plugin set up is fairly simple as you add the following line to your controller: auto_complete_for :tag, :tag_name and the following line in your routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } I have added the controller line to both my tags and questions controller and also mapped resources for both tags and questions in my routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } map.resources :questions, :collection => {:auto_complete_for_tag_tag_name => :get } I have played around with removing either or of the above but can't seem to fix it. Any ideas what I am doing wrong here? UPDATE: My QuestionsController#show action is fishing posts by: @question = Question.find(params[:id])
