  • Pushing app to heroku error

    - by Ryan Max
    Hello, I am getting the following error when I try to push my app to heroku. I saw a similar thread on here, but the issues seemed related to OSX. I am running windows 7 $ git push heroku master Counting objects: 1652, done. Delta compression using up to 4 threads. fatal: object 91f5d3ee9e2edcd42e961ed2eb254d5181cbc734 inconsistent object lengt h (476 vs 8985) error: pack-objects died with strange error error: failed to push some refs to '[email protected]:floating-stone-94.git I'm not sure what this means. I can't find any consistent answers on the internet. I tried re-creating my ssh public key but still the same.

  • Form is creating already loaded attributes in addition to new attributes, how do I ignore the first?

    - by looloobs
    In my application you: Have an admin user that signs on and that user has a role (separate model), then I use the declarative_authorization plugin to give access to certain areas. That admin user can also register new users in the system, when they do this (using Authlogic) they fill out a nested form that includes that new users' role. So what is happening is the role of the admin user is being loaded by the declarative_authorization and then the nested form using the has_many_nested_attributes is loading that existing role as well as the new role for the new user (users can have many roles). Is there some way I can tell the new User being created to ignore the role assigned to the current_user and only create the role in the form for the new user? I have looked through a lot of different things, but it seems to get more complicated that these are nested attributes. Thanks in advance.

  • Need advice with a model - should I choose has_many through

    - by Martin Petrov
    I have something like a blog with posts and tags. I want to add email notification functionality - users can subscribe to one or more tags and receive email notifications when new posts are added. Currently I have a Tag model. There will be a Subscriber model (containing the user's email) Do you think I also need a Subscription table where Subscriber and Tag are joined? .. or I can skip it and directly link Subscriber with Tag?

  • Database layout for an application with geocoding features using geokit

    - by vooD
    I'm developing a real estate web catalogue and want to geocode every ad using geokit gem. My question is what would be the best database layout from the performance point if i want to make search by country, city of the selected country, administrative area or nearest metro station of the selected city. Available countries, cities, administrative areas and metro sations should be defined by the administrator of catalogue and must be validated by geocoding. I came up with single table: create_table "geo_locations", :force => true do |t| t.integer "geo_location_id" #parent geo location (ex. country is parent geo location of city t.string "country", :null => false #necessary for any geo location t.string "city", #not null for city geo location and it's children t.string "administrative_area" #not null for administrative_area geo location and it's children t.string "thoroughfare_name" #not null for metro station or street name geo location and it's children t.string "premise_number" #house number t.float "lng", :null => false t.float "lat", :null => false t.float "bound_sw_lat", :null => false t.float "bound_sw_lng", :null => false t.float "bound_ne_lat", :null => false t.float "bound_ne_lng", :null => false t.integer "mappable_id" t.string "mappable_type" t.string "type" #country, city, administrative area, metro station or address end Final geo location is address it contains all neccessary information to put marker of the real estate ad on the map. But i'm still stuck on search functionality. Any help would be highly appreciated.

  • Validate number of nested attributes

    - by Damien MATHIEU
    Hello, I have a model with nested attributes : class Foo < ActiveRecord::Base has_many :bar accepts_nested_attributes_for :bar end It works fine. However I'd want to be sure that for every Foo, I have at least two Bar. I can't access the bar_attributes in my validations so it seems I can't validate it. Is there any clean way to do so ?

  • Creating relationship between two model instances

    This is probably pretty simple, but here: Say I've got two models, Thing and Tag class Thing < ActiveRecord::Base has_and_belongs_to_many :tags end class Tag < ActiveRecord::Base has_and_belongs_to_many :things end And I have an instance of each. I want to link them. Can I do something like: @thing = Thing.find(1) @tag = Tag.find(1) @thing.tags.add(@tag) If not, what is the best way to do this? Thanks!

  • Unable to read values from object returned from ActiveRecord.find

    - by Venki
    I make the following call to the DB. @patientRegistration = PatientRegistration.find(:all, :conditions=["name = '#{patientName}'"]) Search for patient registration based on a given name. I get a valid @patientRegistration object.When I invoke @patientRegistration.inspect it prints correctly all the values for the object in the DB. But when I try to read a particular attribute (Say id or name) by doing the following: @patientRegistration.id or @patientRegistration.name. I get invalid values. Either its blank or some junk values. I dont understand how inspect is able to retrieve all the values correctly but reading individual attributes gives invalid values. Thanks

  • Newbie question attribute from associated table not showing up in index view

    - by Lauren
    Hi I know this is something simple I am doing wrong. I have three tables, installation, neighborhood, schools Installation: has_many :schools has_many :neighborhoods Neighborhood: has_many :installations has_many :schools Schools: belongs_to :installations belongs_to :neighborhoods I can't figure out how to show the name of the neighborhood the school is located in on the index view. I can get it to show on the show view once I have the school id. But on the index view I can't figure out what to put in the controller that will allow me to access the neighborhood name from the neighborhood_id that is in the School model. I am sure this is so easy and I am screwing up something stupid. HELP!

  • Overriding Ruby's spaceship operator <=>

    - by ericsteen1
    I am trying to override Ruby's <= (spaceship) operator to sort apples and oranges so that apples come first sorted by weight, and oranges second, sorted by sweetness. Like so: module Fruity attr_accessor :weight, :sweetness def <=>(other) # use Array#<=> to compare the attributes [self.weight, self.sweetness] <=> [other.weight, other.sweetness] end include Comparable end class Apple include Fruity def initialize(w) self.weight = w end end class Orange include Fruity def initialize(s) self.sweetness = s end end fruits = [Apple.new(2),Orange.new(4),Apple.new(6),Orange.new(9),Apple.new(1),Orange.new(22)] p fruits #should work? p fruits.sort But this does not work, can someone tell what I am doing wrong here, or a better way to do this?

  • Multiple calculations on the same set of data: ruby or database?

    - by Pierre
    Hi, I have a model Transaction for which I need to display the results of many calculations on many fields for a subset of transactions. I've seen 2 ways to do it, but am not sure which is the best. I'm after the one that will have the least impact in terms of performance when data set grows and number of concurrent users increases. data[:total_before] = Transaction.where(xxx).sum(:amount_before) data[:total_after] = Transaction.where(xxx).sum(:amount_after) ... or transactions = Transaction.where(xxx) data[:total_before]= transactions.inject(0) {|s, e| s + e.amount_before } data[:total_after]= transactions.inject(0) {|s, e| s + e.amount_after } ... Which one should I choose? (or is there a 3rd, better way?) Thanks, P.

  • has_many relation doesn't seems right or logical, some thing like belongs_to_many looks right

    - by Vijendra
    My situation is like this. Company has many users and users may belongs to many companies. And current implementation is something like below. class Company has_many :employments has_many :users, :through = :employments end class Employment belongs_to :company belongs_to :user end class User has_many :employments has_many :companies, :through = :employments #This doesn't looks correct end User has many companies doesn't looks logically meaningful.It must be some thing like belongs_to_many companies. Do I need to use has_and_belongs_to_many? But that also will gives the same meaning. Can some one please suggest the right way for representing these relationships?
