  • What to Learn: Rails 1.2.4 -> Rails 3

    - by Saterus
    I've recently convinced my management that our outdated version of Rails is slowing us down enough to warrant an upgrade. The approach we're taking is to start a fresh project with current technology rather than a painful upgrade. Our requirements for the project have changed and this will be much easier. The biggest problem is actually that my knowledge of Rails is out of date. I've dealt only with Rails 1.2.4 while the rest of the world has moved on long ago. What topics have I missed by being buried in my work instead of keeping up with the current Rails fashion? I'm hesitant to dig through blogs at random because I'm not sure how much has changed between the intervening versions of Rails. It's no use to learn Rails 2.1-2.3 specific stuff that is no longer useful for Rails 3.

  • Can I combine atom feeds from seperate resources into one?

    - by stephemurdoch
    I have two resource for which I would like to generate feeds; they are called podcasts and posts. The problem is that when I include the auto_discovery_link in my templates, I have to add one for each of the two atom feeds that I've generated. The reason why this is a problem is that there are now two feeds for users to choose from, and most people probably won't realise that they need both so will only pick one. Is there a way to combine atom feeds from different resources into one atom feed? Like application.atom or something? I'm using builder to generate the feed.

  • From Sinatra Base object. Get port of application including the base object

    - by Poul
    I have a Sinatra::Base object that I would like to include in all of my web apps. In that base class I have the configure method which is called on start-up. I would like that configure code to 'register' that service with a centralized database. The information that needs to be sent when registering is the information on how to contact this web-service... things like host and port. I then plan on having a monitoring service that will spin over all registered services and occasionally ping them to make sure they are still up and running. In the configure method I am having trouble getting the port information. The 'self.settings.port' variable doesn't seem to work in this method. a) any ideas on how to get the port? I have the host. b) is there a sinatra plug-in that already does something like this so I don't have to write it myself? :-) //in my Sinatra::Base code. lets call it register_me.rb RegisterMe < Sinatra::Base configure do //save host and port information to database end get '/check_status' //return status end //in my web service code require register_me //at this point, sinatra will initialize the RegisterMe object and call configure post ('/blah') //example of a method for this particular web service end

  • Retrieving all objects in code upfront for performance reasons

    - by ming yeow
    How do you folks retrieve all objects in code upfront? I figure you can increase performance if you bundle all the model calls together? This makes for a bigger deal, especially if your DB cannot keep everything in memory def hitDBSeperately { get X users ...code get Y users... code get Z users... code } Versus: def hitDBInSingleCall { get X+Y+Z users code for X code for Y... }

  • 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 :(

  • Does to_json require parameters? what about within rails?

    - by Harry Wood
    Does to_json require parameters? what about within rails? I started getting the error "wrong number of arguments (0 for 1)" when doing myhash.to_json Unfortunately I'm not sure when this error started happening, but I guess it relates to some versions of either rails or the json gem. I suppose my code (in a rails controller) is using the ActiveSupport::JSON version of to_json, rather than the to_josn method supported by the json gem. ActiveSupport::JSON vs JSON In environment.rb I have RAILS_GEM_VERSION = '2.3.2' and also config.gem "json", :version=> '1.1.7' It's just a simple hash structure containing primitives which I want to convert in my controller, and it was working, but now I can't seem to run to_json without passing parameters.

  • Resque: Slow worker startup and Forking

    - by David John
    I'm currently moving my application from a Linode setup to EC2. Redis is currently installed on a remote instance with various worker instances interacting with the queue. Thats all going fantastic. My problem is with the amount of time it takes for a worker to be 'instantiated' and slow forking. Starting a worker will usually take between 30 seconds and a minute(from god.rb starting the worker rake task and the worker actively starting work on the queue). I could live with that, but I've not experienced such a wait time on my current Linode production box so I believe its one of my symptoms to a bigger problem. Next issue is that jobs that took a second or less in my previous environment now seem to take about 5 to 10 times longer.. I'm assuming this must be some sort of issue with my Ubuntu install on EC2? One notable difference is that I'm running REE 1.8.7-2010.01 in my new setup, and REE 1.8.6 on the old Linode boxes. Anyone else experienced these issues?

  • How to make/monitor/deploy daemon processes in JRuby

    - by nazdrug
    I'm currently porting a Rails App currently using REE to JRuby so I can offer an easy-to-install JRuby alternative. I've bundled the app into a WAR file using Bundler which I'm currently deploying to GlassFish. However, this app has a couple of daemon processes and it would be ideal if these could be part of the WAR file, and potentially monitored by Glassfish (if possible). I've looked at QuartzScheduler, and while meets my needs for a couple of things, I have a daemon process that must execute every 20 seconds as it's polling the database for any delayed mail to send. If anyone can provide any insight as to how best to set up daemon processes in a JRuby/Java/Glassfish environment any help will be greatly appreciated! :)

  • Trouble rendering a view inside a generic class

    - by Horace Loeb
    I'm trying to encapsulate the logic for generating my sitemap in a separate class so I can use Delayed::Job to generate it out of band: class ViewCacher include ActionController::UrlWriter def initialize @av = ActionView::Base.new(Rails::Configuration.new.view_path) @av.class_eval do include ApplicationHelper end end def cache_sitemap songs = Song.all sitemap = @av.render 'sitemap/sitemap', :songs => songs Rails.cache.write('sitemap', sitemap) end end But whenever I try ViewCacher.new.cache_sitemap I get this error: ActionView::TemplateError: ActionView::TemplateError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.url_for) on line #5 of app/views/sitemap/_sitemap.builder: I assume this means that ActionController::UrlWriter is not included in the right place, but I really don't know

  • How do I see the whole HTTP request in Rails

    - by akafazov
    Hi, I have a Rails application but after some time of development/debugging I realized that it would be very helpful to be able to see the whole HTTP request in the logfiles - log/development.log, not just the parameters. I also want to have a separate logfile based on user, not session. Any ideas will be appreciated! Angel

  • activemodel for rails < 3

    - by brad
    Does anyone know if activemodel works with 2.3.5? I'm looking for this exact functionality (namely, validations for non-AR objects) and I'm trying to find a clean solution for a Rails 2.3.5 app. Or if anyone knows of a good gem/plugin to use that can mimic activerecord like validations for non AR objects, I'm all ears

  • I want to use the fleximage gem and s3 for storage, but don't want dev/qa/test env's to use s3

    - by Kevin Bedell
    I have a rails app that I'm going to host on engineyard and want to store image files on s3. But I don't know if I want all developer machines to beusing s3 for storage of all our test and dev images. Maybe it's not an issue -- but it seems like a waste to have everyone storing all our images in s3. I've heard of some ppl who store images on s3 'hacking' dev environments to store images locally on the file system -- and then using s3 in prod only. What are other people doing?

  • Rails: using find method to access joined tables for polymorphic relationships

    - by DJTripleThreat
    Ok, I have a generic TimeSlot model that deals with a start_at and an end_at for time spans. A couple models derive from this but I'm referring to one in this question: AppointmentBlock which is a collection of Appointments. I want to validate an AppointmentBlock such that no other AppointmentBlocks have been scheduled for a particular Employee in the same time frame. Since AppointmentBlock has a polymorphic association with TimeSlot, you have to access the AppointmentBlock's start_at and end_at through the TimeSlot like so: appt_block.time_slot.start_at This means that I need to have some kind of join in my :conditions for my find() method call. Here is my code so far: #inside my appointment_block.rb model validate :employee_not_double_booked def employee_not_double_booked unless self.employee_id # this find's condition is incorrect because I need to join time_slots to get access # to start_at and end_at. How can I do this? blocks = AppointmentBlock.find(:first, :conditions => ['employee_id = ? and (start_at between ? and ? or end_at between ? and ?)', self.employee_id, self.time_slot.start_at, self.time_slot.end_at, self.time_slot.start_at, self.time_slot.end_at]) # pseudo code: # collect a list of appointment blocks that end after this # apointment block starts or start before this appointment # block ends that are also associated with this appointment # blocks assigned employee # if the count is great then 0 the employee has been double # booked. # if a block was found that means this employee is getting # double booked so raise an error errors.add "AppointmentBlock", "has already been scheduled during this time" if blocks end end Since AppointmentBlock doesn't have a start_at or an end_at how can I join with the time_slots table to get those conditions to work?

  • Sanitizing CSS in Rails

    - by Erik
    Hello! I want to allow the users of a web app that I'm building to write their own CSS in order to customize their profile page. However I am aware of this opening up for many security risks, i e background: url('javascript:alert("Got your cookies! " + document.cookies'). Hence I am looking for a solution to sanitize the CSS while still allowing as much CSS functionality as possible for my users. So my questions if anyone anyone knows of a gem or a plugin to handles this? I've googled my brains out already so any tips would be really appreciated!

  • Rails database relationships

    - by Danny McClelland
    Hi Everyone, I have three models that I want to interact with each other. Kase, Person and and Company. I have (I think) setup the relationships correctly: class Kase < ActiveRecord::Base #HAS ONE COMPANY has_one :company #HAS MANY PERSONS has_many :persons class Person < ActiveRecord::Base belongs_to :company class Company < ActiveRecord::Base has_many :persons def to_s; companyname; end I have put the select field on the create new Kase view, and the create new Person view as follows: <li>Company<span><%= f.select :company_id, Company.all %> </span></li> All of the above successfully shows a drop down menu dynamically populated with the company names within Companies. What I am trying to do is display the contact of the Company record within the kase and person show.html.erb. For example, If I have a company called "Acme, Inc." and create a new Kase called "Random Case" and choose within the create new case page "Acme, Inc." from the companies drop down menu. I would then want to display "Acme, Inc" along with "Acme, Inc. Mobile" etc. on the "Random Case" show.html.erb. I hope this makes sense to somebody! Thanks, Danny

  • Rails MVC Best Practices for Website Modules

    - by Randuin
    I am just beginning to build my Rails application and thus far I've followed a RESTful design and it's proven much easier to understand and organize the code and structure of the application. I have things like posts and comments. However for the front page. I want to display all the latest posts but also may be in the sidebar display things such as Latest Comments and Latest events. What's the best way to go about this while maintaining the RESTful philosophy?

  • Rails development environment Resque.enqueue does not create jobs

    - by anton evangelatov
    I am having the same problem like Rails custom environment Resque.enqueue does not create jobs , but the solution there doesn't work for me. I'm using Resque for a couple of asynchronous jobs. It works just fine for the staging environment, but for some reason it stopped working on development environment. For example, if I run the following: $ rails c development > Resque.enqueue(MyLovelyJob, 1) Nothing is enqueued. I check Resque using resque-web If I run it on staging - it works just fine. $ rails c staging > Resque.enqueue(MyLovelyJob, 1) I have tried to duplicate the 2 environment, and they seem to use absolutely the same configurations (database.yml , config/environment , etc.), but development is still not working. If I do > Resque.enqueue(UpdateInstancesData, 2) > => true > Resque.info > => { > :pending => 0, > :processed => 0, > :queues => 0, > :workers => 1, > :working => 0, > :failed => 0, > :servers => [ > [0] "redis://127.0.0.1:6379/0" > ], > :environment => "development" > } Any suggestions where to look in order to debug this? I am running the application via foreman.

Could you show me how I can use html tag expression in rspec file?

  • Only show non blank attributes for a model in views in Rails

    - by Senthil
    Say I've a user model and there are bunch of user info, like email, birthdate, location, telephone number etc. What's the simplest way of hiding the attributes that are blank? I've doing something like <% if blog.title.empty? -%> <p>Body: <%=h blog.body %></p> <p>Comments: <%=h blog.comments %></p> <% elsif blog.body.empty? %> <p>Title: <%=h blog.title %></p> <p>Comments: <%=h blog.comments %></p> <% else -%> <p>Title: <%=h blog.title %></p> <p>Body: <%=h blog.body %></p> <% end -%> Clearly that is one ugly child. Other than using partials to render, is there a trick to only show non blank fields? I've been trying to write a helpher method to make the view cleaner, but that's even more ugly. Any help is appreciated.
