  • Get Rails to save a record to the database in a non-UTC time

    - by Shaun
    Is there a way to get Rails to save records to the database without it automagically converting the timestamp into UTC before saving? The problem is that I have a few models that pull data from a legacy database that saves everything in Mountain Time and occasionally I have to have my Rails app write to that database. The problem is that every time it does, it converts the time I give it from Mountain Time to UTC, which is 6-7 hours ahead (depending on DST)! Needless to say, this really messes with reporting on that database. If I could get around doing this, I would. Unfortunately, I can't do anything about the fact that this other database uses a different timezone, nor can I really get away from the need for this app to save to that database occasionally. If I could just get Rails to stop trying to help me, it'd be great.

  • With Rails 3 routes, how do you only allow a requests from 127.0.0.1?

    - by micah
    I'm writing an app where several of the routes should only be accessible from localhost. It looks like this is possible with the new routing system. http://www.railsdispatch.com/posts/rails-3-makes-life-better This has examples of restricting routes based on IP address, and setting up an IP address blacklist for your routes, but I'm interested in a whitelist with just one IP address. It would be cool if something like this worked: get "/posts" => "posts#show", :constraints => {:ip => '127.0.0.1'} But it didn't. Am I just missing the right syntax?

  • How do I stop the scriptaculous blind-down effect from flickering when element has padding?

    - by ro
    Hi all, it seems that when the blind down effect is used on an element with padding it looks a bit awkward. It seems to blind down too far and then jumps back. It's a very subtle thing but is really annoying. I don't have an online example but if you go to the demo on github and give the element a padding-top or bottom with firebug or something you'll see what I mean. http://wiki.github.com/madrobby/scriptaculous/effect-blinddown Anybody found a way to stop it?

  • Does a rails production.log store indefinitely?

    - by Trip
    If it doesn't, what's the half-life of it? It it does, where can find that information? On my server I found a few logs for each of my releases. But they only date back a few days. Specifically, I am looking for emails that were sent while my mail server was down two weeks ago.

  • Rails Load Data into Application every time a New User is Created

    - by looloobs
    Hi I am trying to figure out the "right" way to do this. In my application every time I create a new user I want to have specific data loaded into an associated table. The associated table is a different preset lists. So a User has many lists and those lists have many items. Some of those Items I want to be loaded when the User is created. I really don't know how to go about doing this but I am guessing something like: create User after_create: create Lists (need already existing data for the list names) after_create List then populate Items table with existing data for these Lists. Should I be using seed data for this? Is that alright for production and if so how exactly would I go about doing that. Any guidance or other recommendations are greatly appreciated.

  • How do I model a has_many :through and with aggregation in Rails?

    - by Angela
    How do I model having multiple Addresses for a Company and assign a single Address to a Contact? Contacts belong_to a Company. A Company has_many Contacts. A Company also has_many Addresses. And each Contact belongs_to an Address. How do I model this? I have Model/Contacts.rb belong_to :Company belong_to :Address (?) Model/Company.rb has_many :Contacts has_many :Addresses Address is an aggregation of :street1, :street2, :city, :state, :zip so not clear exactly what to do there. So what would I do in my _form so that when I have a contact/new I am able to either default to a main address or select one of the others? If none of them match, adding for a Contact makes that address available to any subsequent contact?

  • Pre-packaged Rails applications

    - by Craig
    Seems like most Rails applications have similar 'base' functionality. As such, it seems that there would be value in having pre-build Rails applications at various functionality points such as: basic User model with authentication using Authlogic #1 + openid integration #2 + authorization using declarative_authorization #3 + Administration module #4 + a Profile model Themes (useful stylesheets and such) Friendship model Geocoding ... In addition to the basic MVC stuff, these applications would include: testing harnesses seed data git support One could choose start from any of these functionality points. Other than the sample application that are available with the various gems/plugins, are there projects such as these? If not, I would certainly be willing to contribute what I have.

  • rails controller defaults to respond with application/xml in production

    - by Dave Paroulek
    I have a standard contacts_controller.rb with index action that responds as follows: respond_to do |format| format.html format.xml { render :xml => @contacts } end In development, it works as intended: when I browse to http://localhost:3000/contacts, I get an html response. But, when I start the app using capistrano on a remote Ubuntu server and browse to the same url, I get an xml response. If I go to http://remote_host:8000/contacts.html, then I see the html response. If I comment out the format.xml { render :xml => @contacts }, then I see the desired html response. Pretty sure I'm missing something subtle about difference between Rails development and production modes. Any ideas about what I'm overlooking? Thanks, - Dave

  • Rails application and multilingual content, Model dilemma

    - by dakull
    I'm writing in Rails a website that will be multilingual, for the application translation part i will use the simple I18n gem, for messages and everything related. Yet, all the content must be translated, and we're talking about lots of pages, that will be stored into the database ( like articles, news, etc. ) For now, I'm thinking of two approaches: Lets say i have a Pages table, the content in diff. languages, i will be storing it in a different table called PagesContent that will belong_to Pages and also to a Languages table. The problem here, is that I'll essentially duplicate the no. of tables needed. Pros: flexibility, in the box validation To skip that duplication i can serialize a hash into the content column of Pages, containing the translation. The problem here, is validation, arguably more code to write, and less flexibility when adding a new language. Pros: Less tables. Any other idea ?

  • 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

  • How do I create the Controller for a Single Table Inheritance in Rails?

    - by Angela
    I am setting up the Single Table Inheritance, using ContactEvent as the Model that ContactEmail, ContactLetter, and ContactCall will all inherit. But I'm stumped on how to create the routing and the controller. For example, let's say I want to create a new ContactEvent with type Email. I would like a way to do the following: new_contact_event_path(contact, email) This would take the instance from Contact model and from Email model. Inside, I would imagine the contact_event_controller would need to know... @contact_event.type = (params[:email]) # get the type based on what was passed in? @contact_event.event_id = (params[:email]) #get the id for the correct class, in this case Email.id Just not sure how this works....

  • What would you use for auto completion in Rails app?

    - by Andrei
    I want to use auto-completion in a number of fields (5-7) in my forms. There is a screencast on auto-completion with Prototype library by Ryan Bates ( http://railscasts.com/episodes/102-auto-complete-association). On the other hand, I have noticed that quite many guys suggest jQuery for this task ( http://jquery.bassistance.de/autocomplete/demo/). And I guess, there was probably some development last year(s), so I ask you - what would you use nowadays to auto-complete your form fields and why? BTW, I still have an open question on auto completion for HABTM association: http://stackoverflow.com/questions/1510935/how-to-do-habtm-management-with-auto-completion-in-rails

  • Is Amazon SQS the right choice here? Rails performance issue.

    - by ole_berlin
    I'm close to releasing a rails app with the common networking features (messaging, wall, etc.). I want to use some kind of background processing (most likely Bj) for off-loading tasks from the request/response cycle. This would happen when users invite friends via email to join and for email notifications. I'm not sure if I should just drop these invites and notifications in my Database, using a model and then just process it with a worker process every x minutes or if I should go for Amazon SQS, storing the messages and invites there and let my worker retrieve it from Amazon SQS for processing (sending the invites / notifications). The Amazon approach would get load off my Database but I guess it is slower to retrieve messages from there. What do you think?

  • How can I prevent double file uploading with Amazon S3?

    - by Tony
    I decided to use Amazon S3 for document storage for an app I am creating. One issue I run into is while I need to upload the files to S3, I need to create a document object in my app so my users can perform CRUD actions. One solution is to allow for a double upload. A user uploads a document to the server my Rails app lives on. I validate and create the object, then pass it on to S3. One issue with this is progress indicators become more complicated. Using most out-of-the-box plugins would show the client that file has finished uploading because it is on my server, but then there would be a decent delay when the file was going from my server to S3. This also introduces unnecessary bandwidth (at least it does not seem necessary) The other solution I am thinking about is to upload the file directly to S3 with one AJAX request, and when that is successful, make a second AJAX request to store the object in my database. One issue here is that I would have to validate the file after it is uploaded which means I have to run some clean up code in S3 if the validation fails. Both seem equally messy. Does anyone have something more elegant working that they would not mind sharing? I would imagine this is a common situation with "cloud storage" being quite popular today. Maybe I am looking at this wrong.

  • Mocha expects method

    - by Masha
    So my situation is: I have a 2 modules that have the same structure like that: module Module1 class Config def fee_rate 2 end end end So, say, Module2 would have class Config with the method fee_rate, just with a different value (those are actually implemented in a rails engine, but it shouldn't matter) and then my model can use either Module1 or Module2 to get the fee rate value like that: def config @config ||= "#{module_name.titleize}::Config".constantize.new @config end def get_value config.get_fee * some_other_value end What I'm trying to test is if get_fee function was called on the correct class: "#{model.module_name.titleize}::Config".constantize.any_instance.expects(:get_fee).at_least_once model.get_value and on the line when I call get_value I get the following error - undefined method `*' for nil:NilClass. I'm completely lost now, so I'd appreciate any help and ideas.
