  • globalize2 with xml/json support

    - by Philipp Bolliger
    I'm implementing a distributed application, server with rails and mobile clients in objective c (iPhone). To enable internationalization, I use the rails plugin 'globalize2' by joshmh. However, it turned out that this plugin does not translate attributes when calling to_xml or to_json on an ActiveRecord. Does anyone know of a workaround / patch? Do you have any ideas how to fix this, where to alter globalize2? Using: Rails 2.3.5 globalize2: commit from 2010-01-11

  • uninitialized constant MysqlCompat::MysqlRes (using mms2r gem)

    - by William
    Hi, moved a rails app of mine onto a new server and had to install a few gem dependencies. However, after installing the mysql gem I get the error, uninitialized constant MysqlCompat::MysqlRes, whenever I try to run a rake command that involves the mysql database. It seems I only get this error when I require the mms2r gem. Has anyone ever heard of this? I'm running mysql 2.8.1 gem.

  • 1-st level routes for multiple resources in Rails

    - by Leonid Shevtsov
    I have a simple SEO task. There's a City model and a Brand model, and I have to create 1st-level URLs for both (e.g. site.com/honda and site.com/boston). What's the preferred routing/controller combination to do this in Rails? I can only think of map.connect '/:id', :controller => 'catchall', :action => 'index' class CatchallController < ApplicationController def index if City.exists?(:slug => params[:id]) @city = City.find_by_slug!(params[:id]) render 'cities/show' else @brand = Brand.find_by_slug!(params[:id]) render 'brands/show' end end end but it seems to be very un-Rails to put such logic into the controller. (Obviously I need to make sure that the slugs don't overlap in the models, that's done).

  • Rails: updating an association

    - by Sam
    I have a Reservation model which belongs_to a Sharedorder and so a Sharedorder has_many reservations. Give you a little background. I sharedorder has many reservations and each reservation can have an amount. A sharedorder has three status: 1) reserved, 2) confirmed, 3) and purchased. Here is my problem. When a reservation gets added to a sharedorder or an existing reservation's amount is updated I need this to affect the associated sharedoder because the status listed latter should only change when 100% of the reservations have been placed and so on. Here are the things I have tried: . class Reservation < ActiveRecord::Base before_save :sharedorder_reserved_status def sharedorder_reserved_status if self.sharedorder.reserved_percent(reservations_to_be_added) >= 100 && !self.sharedorder.reserved self.sharedorder.update_attribute(:reserved, true) self.sharedorder.update_attribute(:reserved_at, Time.now) end end def reservations_to_be_added if self.new_record? self.amount elsif self.amount_changed? self.amount - self.amount_was else 0 end end end And then in the Sharedorder model: class Sharedorder < ActiveRecord::Base def reserved_percent(amount_change) (((reserved_sum + amount_change).to_f / self.product.twenty_hq_size.to_f)*100).to_i end def reserved_sum if !@reserved_sum reserved_sum = 0 reserved_reservations.collect {|x| reserved_sum += x.amount } reserved_sum else @reserved_sum end end def reserved_reservations @reserved_reservations ||= Reservation.find(:all, :conditions => ['canceled = ? AND sharedorder_id = ?', false, self.id ]) end end I have also tried :touch => true on the reservation model to update the sharedorder put for some reason it doesn't seem to include the latest reservation being added or being updated. So what I'm trying to do is update the status of the sharedorder if a certain percent is reached and I have to send the additional amounts the the sharedorder for it to know to include additional reservations or updates on existing ones. How should I do this?

  • Database locking: ActiveRecord + Heroku

    - by JP
    I'm building a Sinatra based app for deployment on Heroku. You can imagine it like a standard URL shortener but where old shortcodes expire and become available for new URLs (I realise this is a silly concept but its easier to explain this way). I'm representing the shortcode in my database as an integer and redefining its reader to give a nice short and unique string from the integer. As some rows will be deleted, I've written code that goes thru all the shortcode integers and picks the first free one to use just before_save. Unfortunately I can make my code create two rows with identical shortcode integers if I run two instances very quickly one after another, which is obviously no good! How should I implement a locking system so that I can quickly save my record with a unique shortcode integer? Here's what I have so far: Chars = ('a'..'z').to_a + ('A'..'Z').to_a + ('0'..'9').to_a CharLength = Chars.length class Shorts < ActiveRecord::Base before_save :gen_shortcode after_save :done_shortcode def shortcode i = read_attribute(:shortcode).to_i return '0' if i == 0 s = '' while i > 0 s << Chars[i.modulo(CharLength)] i /= 62 end s end private def gen_shortcode shortcode = 0 self.class.find(:all,:order=>"shortcode ASC").each do |s| if s.read_attribute(:shortcode).to_i != shortcode # Begin locking? break end shortcode += 1 end write_attribute(:shortcode,shortcode) end def done_shortcode # End Locking? end end

  • Agile web development with Rails 4 interface difficulties

    - by Luke Annison
    I've been following along with the examples in the book in making a online catalog and am having a couple of discouraging difficulties in Chapter 8 task C: Catalog display. I have input the code for the stylesheets as instructed but it has created a slightly skewed result as compared to what is shown in the book. Whilst minor and aesthetic in nature its a little shock to my confidence and slightly irritating when trying to carry on through the book. I have too little rep to post a pic, but heres the link: http://s11.postimage.org/3pwlzfiwj/Screen_Shot_2012_10_08_at_22_29_56.png) As you can see the boarder seems a little confused and the image at the top is covering the header text. I've been through the code time and time again but can't seem find out where I've gone wrong. Could anybody give me some clues?

  • How to disable activerecord cache logging in rails

    - by user1508459
    I'm trying to disable logging of caching in production. Have succeeded in getting SQL to stop logging queries, but no luck with caching log entries. Example line in production log: CACHE (0.0ms) SELECT merchants.* FROM merchants WHERE merchants.id = 1 LIMIT 1 I do not want to disable all logging, since I want logger.debug statements to show up in the production log. Using rails 3.2.1 with Mysql and Apache. Any suggestions?

  • Schema for storing "binary" values, such as Male/Female, in a database

    - by latentflip
    Intro I am trying to decide how best to set up my database schema for a (Rails) model. I have a model related to money which indicates whether the value is an income (positive cash value) or an expense (negative cash value). I would like separate column(s) to indicate whether it is an income or an expense, rather than relying on whether the value stored is positive or negative. Question: How would you store these values, and why? Have a single column, say Income, and store 1 if it's an income, 0 if it's an expense, null if not known. Have two columns, Income and Expense, setting their values to 1 or 0 as appropriate. Something else? I figure the question is similar to storing a person's gender in a database (ignoring aliens/transgender/etc) hence my title. My thoughts so far Lookup might be easier with a single column, but there is a risk of mistaking 0 (false, expense) for null (unknown). Having seperate columns might be more difficult to maintain (what happens if we end up with a 1 in both columns? Maybe it's not that big a deal which way I go, but it would be great to have any concerns/thoughts raised before I get too far down the line and have to change my code-base because I missed something that should have been obvious! Thanks, Philip

  • What can be inside a class that derive from OmniAuth?

    - by Richard77
    I have the following class class Identity < OmniAuth:: Identity:: Models:: ActiveRecord attr_accessible :email, :name, :password_digest, :password, :password_confirmation end I wonder if the above properties are the only ones allowed for a class that derive from a OmniAuth. I wish I could add some more like FirstName, LastName, age, gender, and so on. Do I need to create an other model for those properties or can I just add them to the Identity model? Thanks for helping.

  • Regarding Authlogic and page redirection.

    - by Paddy
    I am using authlogic for authentication in my Rails app. Have named routes for the frequent actions, viz: map.login "login", :controller = "user_sessions", :action = "new" map.logout "logout", :controller = "user_sessions", :action = "destroy" map.register "register", :controller = "users", :action = "new" map.edit 'user/edit/:id', :controller = "users", :action = "edit" But also in my routes.rb i have these automatically created REST routes too: map.resources :user_sessions map.resources :users The problem now is that a user can login from two different routes. Ex: From, http://localhost/login and also from http ://localhost/user_sessions/new. How do i restrict access only from the named route i have defined and not allow from user_sessions/new?

  • please recommend a rails based CMS

    - by paul
    Hello, I am searching for a rails-based CMS that provide rich text editing feature (e.g. I need an interface very similar to that of Wordpress where you can easily style up your static pages and upload pictures without knowing any css or html) AND easy to be dropped into an existing rails application. Camtose, RadiantCMS and few other ones did not seem to offer the rich interface I was looking for. RefineryCMS had conflict with my existing user authentication and I did not really find a solution to it. I am just wondering if there are any rails based cms that can meet my needs. Please advise if you know of any such rails-based CMS. Thank you for your help!

  • Handling JSON and HTML templates in jQuery

    - by Toby Hede
    I have an ajax-enabled site that presents a lot of dynamic content by interpolating JSON values with HTML. This all works fine. BUT it means I have significant amounts of HTML all through my JavaScript. For example: var template = "<div>Foo: {bar}</div><div>Blah: {vtha}</div>"; template.interpolate({bar:"bar",blah:"vtha"}); I have cut this down a fair bit - some of my dynamic elements have quite a lot of HTML and a lot going on. I am using jQuery and I am building on Rails, so if there is something smart in either framework, that would be great. For reference, the String interpolation function used above is: String.prototype.interpolate = function (o) { return this.replace(/{([^{}]*)}/g, function (a, b) { var r = o[b]; return typeof r === 'string' || typeof r === 'number' ? r : a; } ); };

  • Scoping two models on approved

    - by Shaun Frost Duke Jackson
    I have three models (Book,Snippet,User) and I'd like to create a scope for where(:approved = true) I'm doing this so I can use the merit gem to define ranking based on count of approved. I'm thinking that writing this as a scope might be to complex but I don't know as I've just started leaning scopes. I've currently got this in my Book & Snippet Model: scope :approved, -> { where(approved: true) } I've playing around with this in my user model but I don't think it's correct: scope :approved, joins(:books && :snippets) Could anyone help start me off or give me some suggestions on what to read?

  • Rails Functional Test Failing Due to Association

    - by Koby
    I have an accounts model that holds some basic account info (account name, website, etc). I then have a user model that has the following in the app/models/user.rb belongs_to :account I also have the following in my routes.rb map.resources :account, :has_many => [:users, :othermodel] the problem I'm facing is that the following test is failing: test "should create user" do assert_difference('User.count') do post :create, :user => { } #this is the line it's actually failing on end assert_redirected_to user_path(assigns(:user)) #it doesn't get here yet end The error it gives is "Can't find Account without ID" so I kind of understand WHY it's failing, because of the fact that it doesn't have the account object (or account_id as it were) to know under what account to create the user. I have tried variations of the following but I am completely lost: post :create, :user => { accounts(:one) } #I have the 'fixtures :accounts' syntax at the top of the test class post :create, [accounts(:one), :user] => { } post :create, :user => { accounts(:one), #other params for :user } and like I said, just about every variation I could think of. I can't find much documentation on doing this and this might be why people have moved to Factories for doing test data, but I want to understand things that come standard in Rails before moving onto other things. Can anyone help me get this working?
