• Updating protected attributes using update_all

  - by Jack

  Since you cannot use the normal 'update' and 'update_attribute' methods from ActiveRecord to update a protected attribute, is the following the best way to update an attribute for a single user? User.update_all("admin = true","id = 1") I'm guessing this doesn't lie in the 'best practice' category, so I'm just curious if there is a more appropriate way.

• Why getting active record error when trying to work on arrays?

  - by keruilin

  I have the following association in my User model: has_and_belongs_to_many :friends, :class_name => 'User', :foreign_key => 'friend_id' I have the following uniqueness constraint in my user_users table: UNIQUE KEY `no_duplicate_friends` (`user_id`,`friend_id`) In my code, I am retrieving a user's friends -- friends = user.friends. friends is an array. I have a scenario where I want add the user with all those friends to the friends array. Ex: friends << user_with_all_those_homies However, I get the following error: ActiveRecord::StatementInvalid: Mysql::Error: Duplicate entry '18-18' for key 'no_duplicate_friends': INSERT INTO `users_users` (`friend_id`, `user_id`) VALUES (18, 18) What gives?

• Is there a SaaS for logging user activity?

  - by JoshL

  In almost every app that I build I create some kind of user log table to log various activities that my actual USERS (not visitors, but someone with an account) perform on the site. This is primarily used for customer service issues to allow me to pull up a record of the pages and actions that a user has visited. The downside to this is the size of the UserLogs table. It gets immense. I'm not sure if it is common practice or not for others to log INDIVIDUAL (not aggregate like Google Analytics) user behavior to a database, but if it is I'm wondering if any form of a SaaS exists to help offload this task? I essentially need a RESTful API that lets me store and retrieve individual user activity quickly and securely. Anyone know of any or am I the only one who has this issue?

• are fixtures loaded when using the sql dump to create a test database

  - by Josh Moore

  Because of some non standard table creation options I am forced to use the sql dump instead of the standard schema.rb (i.e. I have uncommented this line in the environment.rb config.active_record.schema_format = :sql). I have noticed that when I use the sql dump that my fixtures do not seem to be loaded into the database. Some data is loaded into it but, I am not sure where it is coming from. Is this normal? and if it is normal can anybody tell me where this other data is coming from?

• Does it make sense to fragment cache static partials

  - by ash34

  Hi, I have my views and layouts split into multiple partials, some of them are static partials i.e, no data from the database being displayed here. Does it make sense to cache these to prevent the erb templating system from generating the html each time or it only makes sense to cache in situations where something needs to be retrieved from the db each time. thanks, ash

• How do I find where id does not match any of an array?

  - by Nick5a1

  I have a Workout model that has and belongs to many Equipment models. I have an array of some Equipment IDs. I want to find all Workouts that don't have any Equipment assigned that matches any of the array of Equipment IDs. So, if my array = [2,3,5] I want to find all workouts where the assigned equipment ids does not include 2, 3 or 5. EDIT: Workout.joins(:equipment).where("equipment.id not in(?)",[2,3,5]).uniq Assuming five instances of Equipment, the code above returns workouts with equipment.ids 1 and 4 (good), but also returns partial matches for example Workouts with equipment.id = [1,2], [1,2,3].

• Best wrapper for simultaneous API requests?

  - by bluebit

  I am looking for the easiest, simplest way to access web APIs that return either JSON or XML, with concurrent requests. For example, I would like to call the twitter search API and return 5 pages of results at the same time (5 requests). The results should ideally be integrated and returned in one array of hashes. I have about 15 APIs that I will be using, and already have code to access them individually (using simple a NET HTTP request) and parse them, but I need to make these requests concurrent in the easiest way possible. Additionally, any error handling for JSON/XML parsing is a bonus.

• How can I make sure the Sphinx daemon runs?

  - by Ethan

  I'm working on setting up a production server using CentOS 5.3, Apache, and Phusion Passenger (mod_rails). I have an app that uses the Sphinx search engine and the Thinking Sphinx gem. According to the Thinking Sphinx docs... If you actually want to search against the indexed data, then you’ll need Sphinx’s searchd daemon to be running. This can be controlled using the following tasks: rake thinking_sphinx:start rake ts:start rake thinking_sphinx:stop rake ts:stop What would be the best way to ensure that this takes place in production? I can deploy my app, then manually run rake thinking_sphinx:start, but I like to set things up so that if I have to bounce the server, everything will come back up. Should I put a call to that Rake task in an initializer? Or something in rc.local?

• Problem with Active Record

  - by kshchepelin

  Hello everyone. Lets assume we have a User model. And user can plan some activities. The number of types of activities is about 50. All activities have common properties, such as start_time, end_time, user_id, etc. But each of them has some unique properties. Now we have each activity living in its own table in DB. And thats why we have such terrible sql queries like SELECT * FROM `first_activities_table` WHERE (`first_activity`.`id` IN (17,18)) SELECT * FROM `second_activities_table` WHERE (`second_activity`.`id` = 17) ..... SELECT * FROM `n_activities_table` WHERE (`n_activity`.`id` = 44) About 50 queries. That's terrible. There are different ways to solve this. Choose the activity type with the biggest number of properties, create the table 'Activities' and have STI model. But this way we must name our columns in uncomfortable way and often the record in that table would have some NULL fields. Also STI model, but having columns, common for all of activity types and some blob column with serialized properties. But we have to do some search on activities - there can be a problem. And serialization is quite slow. Please help me dealing with this. Maybe my problem has quite different solution that will fit my needs. Thanks for help.

• require_owner code to limit controller actions not recognizing current user as owner

  - by bgadoci

  I am trying to restrict access to certain actions using a before_filter which seems easy enough. Somehow the ApplicationController is not recognizing that the current_user is the owner of the user edit action. When I take the filter off the controller correctly routes the current_user to their edit view information. Here is the code. Link to call edit action from user controller (views/questions/index.html.erb): <%= link_to "Edit Profile", edit_user_path(:current) %> ApplicationController (I am only posting the code that I think is affecting this but can post the whole thing if needed). class ApplicationController < ActionController::Base def require_owner obj = instance_variable_get("@#{controller_name.singularize.camelize.underscore}") # LineItem becomes @line_item return true if current_user_is_owner?(obj) render_error_message("You must be the #{controller_name.singularize.camelize} owner to access this page", root_url) return false end end and the before_filter class UsersController < ApplicationController before_filter :require_owner, :only => [:edit, :update, :destroy] #... end I simply get the rendering of the error message from the ApplicationController#require_owner action.

• Counting distinct and duplicate attribute values in an array

  - by keruilin

  I have an array of users that's sorted in descending order based on total_points. I need to find the rank of each user in that array. The issue is that more than one user can have the same total points and, thus, the same rank. For example, three users could be in 3rd place with 200 Points. Here's my current code: class Leader < ActiveRecord::Base def self.points_leaders all_leaders = all_points_leaders # returns array of users sorted by total_points in desc order all_leaders_with_rank = [] all_leaders.each do |user| rank = all_leaders.index(user)+1 all_leaders_with_rank << Ldr.new(rank, user) # Ldr is a Struct end return all_leaders_with_rank end end How must I modify the code so that the correct rank is returned, and not just the value of the index position?

• Overriding rubies spaceship operator <=>

  - by ericsteen1

  I am trying to override rubies <= (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?

• ActiveRecord field normalization

  - by Bill

  I feel bad asking this question, as I thought I knew enough about Activerecord to answer this myslef. But such is the way of having SO available ... I'm trying to remove the commas from a field in a model of mine, I want the user to be able to type a number , ie 10,000 and that number be stored in the database as 10000. I was hoping that I could do some model-side normalization to remove the comma. I don't want to depend on the view or controller to properly format my data. I tried ; before_validation :normalize def normalize self['thenumber'] = self['thenumber'].to_s.gsub(',','') end no worky :(

• 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!

• Displaying pic for user through a question's answer

  - by bgadoci

  Ok, I am trying to display the profile pic of a user. The application I have set up allows users to create questions and answers (I am calling answers 'sites' in the code) the view in which I am trying to do so is in the /views/questions/show.html.erb file. It might also be of note that I am using the Paperclip gem. Here is the set up: Associations Users class User < ActiveRecord::Base has_many :questions, :dependent => :destroy has_many :sites, :dependent => :destroy has_many :notes, :dependent => :destroy has_many :likes, :through => :sites , :dependent => :destroy has_many :pics, :dependent => :destroy has_many :likes, :dependent => :destroy end Questions class Question < ActiveRecord::Base has_many :sites, :dependent => :destroy has_many :notes, :dependent => :destroy has_many :likes, :dependent => :destroy belongs_to :user end Answers (sites) class Site < ActiveRecord::Base belongs_to :question belongs_to :user has_many :notes, :dependent => :destroy has_many :likes, :dependent => :destroy has_attached_file :photo, :styles => { :small => "250x250>" } end Pics class Pic < ActiveRecord::Base has_attached_file :profile_pic, :styles => { :small => "100x100" } belongs_to :user end The /views/questions/show.html.erb is rendering the partial /views/sites/_site.html.erb which is calling the Answer (site) with: <% div_for site do %> <%=h site.description %> <% end %> I have been trying to do things like: <%=image_tag site.user.pic.profile_pic.url(:small) %> <%=image_tag site.user.profile_pic.url(:small) %> etc. But that is obviously wrong. My error directs me to the Questions#show action so I am imagining that I need to define something in there but not sure what. Is is possible to call the pic given the current associations, placement of the call, and if so what Controller additions do I need to make, and what line of code will call the pic? UPDATE: Here is the QuestionsController#show code: def show @question = Question.find(params[:id]) @sites = @question.sites.all(:select => "sites.*, SUM(likes.like) as like_total", :joins => "LEFT JOIN likes AS likes ON likes.site_id = sites.id", :group => "sites.id", :order => "like_total DESC") respond_to do |format| format.html # show.html.erb format.xml { render :xml => @question } end end
