  • Bizarre Bug with our Rails app in IE

    - by Callmeed
    We're experiencing a really bizarre bug in our Rails 2.3.4 app. This bug only happens in Internet Explorer (7 and 8). Here's what happens: A new customer creates an account at https://domain.com/signup/free (notice no subdomain) Their account is identified by a subdomain like "example.domain.com" After signing up, they get a welcome screen with a link to their account's home page They follow the link, then click the "log in" button and attempt to login Even though they provide valid credentials, the app redirects back to their account's root url ... they can never reach their admin area The only way they can login (on IE) is by quitting and re-opening IE ... then it works fine ... Something with their initial session is preventing them from logging in. If it matters, we are using restful_authentication and the ssl_requirement plugin ... I'm not sure if one or both of those has a problem with IE but we are stumped here. Also, I've read IE has an issue with subdomains that contain underscores ... this isn't what's going on.

  • Fully custom validation error message with Rails

    - by marcgg
    Using Rails I'm trying to get an error message like "The song field can't be empty" on save. Doing the following: validates_presence_of :song_rep_xyz, :message => "can't be empty" ... only displays "Song Rep XYW can't be empty", which is not good because the title of the field is not user friendly. How can I change the title of the field itself ? I could change the actual name of the field in the database, but I have multiple "song" fields and I do need to have specific field names. I don't want to hack around rails' validation process and I feel there should be a way of fixing that.

  • Yet another Rails routing question

    - by danhere
    I can't seem to grasp the Rails routing just yet. I want to be able to link the site to, for example, ...com/store/xbox360/Mass Effect 2 (which is /store(my controller)/:system/:title). I have the database entries that include the :system and :title variables (?). How would I route these to show up and filter these entries? Or is this something I need to set up in the controller? I'm lost. Thanks so much for your help.

  • 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?

  • Is there a way to make the flash[:notice] appear above, or before, the flash[:error] ?

    - by GoodGets
    So, I'd like to be able to display both a flash[:notice] and a flash[:error] on the same action, but I'd like for the :notice to always be displayed above (or before) the error. Is there a way to do this? In my controller, I thought I could just code the flash[:error] before the flash[:notice], so that rails will display it correctly, and it does a vast majority of the time. But every now and then they are randomly switched, and I can't seem to figure out why. So, how can I ensure that a flash[:notice] is always displayed above an :error ?

  • 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

  • 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 :(

  • Methodology for a Rails app

    - by Aaron Vegh
    I'm undertaking a rather large conversion from a legacy database-driven Windows app to a Rails app. Because of the large number of forms and database tables involved, I want to make sure I've got the right methodology before getting too far. My chief concern is minimizing the amount of code I have to write. There are many models that interact together, and I want to make sure I'm using them correctly. Here's a simplified set of models: class Patient < ActiveRecord::Base has_many :PatientAddresses has_many :PatientFileStatuses end class PatientAddress < ActiveRecord::Base belongs_to :Patient end class PatientFileStatus < ActiveRecord::Base belongs_to :Patient end The controller determines if there's a Patient selected; everything else is based on that. In the view, I will be needing data from each of these models. But it seems like I have to write an instance variable in my controller for every attribute that I want to use. So I start writing code like this: @patient = Patient.find(session[:patient]) @patient_addresses = @patient.PatientAddresses @patient_file_statuses = @patient.PatientFileStatuses @enrollment_received_when = @patient_file_statuses[0].EnrollmentReceivedWhen @consent_received = @patient_file_statuses[0].ConsentReceived @consent_received_when = @patient_file_statuses[0].ConsentReceivedWhen The first three lines grab the Patient model and its relations. The next three lines are examples of my providing values to the view from one of those relations. The view has a combination of text fields and select fields to show the data above. For example: <%= select("patientfilestatus", "ConsentReceived", {"val1"="val1", "val2"="val2", "Written"="Written"}, :include_blank=true )% <%= calendar_date_select_tag "patient_file_statuses[EnrollmentReceivedWhen]", @enrollment_complete_when, :popup=:force % (BTW, the select tag isn't really working; I think I have to use collection_select?) My questions are: Do I have to manually declare the value of every instance variable in the controller, or can/should I do it within the view? What is the proper technique for displaying a select tag for data that's not the primary model? When I go to save changes to this form, will I have to manually pick out the attributes for each model and save them individually? Or is there a way to name the fields such that ActiveRecord does the right thing? Thanks in advance, Aaron.

  • 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

  • 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

  • Rails Devise: How to access sign up page after signed in?

    - by Junior rails programmer
    hi All, I am new with rails and i am using "devise" gem for authentication purposes. At first i add a new user through default sign up page (E.g./users/sign_up) Then, i made "sign_up" page only available to signed_in users by following instructions from Devise before filter that prevents access to "new_user_registration_path" unless user is signed-in Now, after sign in process when i try open sign up page it always directs me to root_path! How can i access sign up page? My "roots.rb" file as follows: Example::Application.routes.draw do devise_for :users, :controllers => { :registrations => 'registrations'} resources :companies resources :orders resources :customers root :to => "welcome#index" end Thank you all!

  • Any special assertion to test if the resulting integer lies within a range

    I would like to test if an instance variable lies in a range of numbers. I solved the problem by using assert_in_delta but would like to know if there is a formal assertion for this. #part of the tested class def initialize(value = 70 + rand(30)) @value = value end #test_value.rb class ValueTestCase < Test::Unit::TestCase def test_if_value_in_range assert_in_delta(85, p.value, 15) end end

  • 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

  • Is there an API for listing queues and exchanges on RabbitMQ?

    - by parsenome
    I've looked quite a bit, but I haven't been able to find a good programmatic way to list the queues on a RabbitMQ server. This is important because I need to clean up my queues and exchanges when I'm done with them. I don't always have a good "done" event that can be used to trigger a cleanup, so I'd like to do it with more of a garbage collection model. If I can list the queues, I can verify that the objects that they're related to shouldn't be producing more entries and clean them up. I know I can use rabbitmqctl to do it, but that needs elevated privileges. Since I haven't been able to find a way to list the queues programmatically, I've been keeping a list of names in the database. That works, but it's ugly.

  • 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.

  • Validate HAML from ActiveRecord: scope/controller/helpers for link_to etc?

    - by Chris Boyle
    I like HAML. So much, in fact, that in my first Rails app, which is the usual blog/CMS thing, I want to render the body of my Page model using HAML. So here is app/views/pages/_body.html.haml: .entry-content= Haml::Engine.new(body, :format => :html5).render ...and it works (yay, recursion). What I'd like to do is validate the HAML in the body when creating or updating a Page. I can almost do that, but I'm stuck on the scope argument to render. I have this in app/models/page.rb: validates_each :body do |record, attr, value| begin Haml::Engine.new(value, :format => :html5).render(record) rescue Exception => e record.errors.add attr, "line #{(e.respond_to? :line) && e.line || 'unknown'}: #{e.message}" end end You can see I'm passing record, which is a Page, but even that doesn't have a controller, and in particular doesn't have any helpers like link_to, so as soon as a Page uses any of that it's going to fail to validate even when it would actually render just fine. So I guess I need a controller as scope for this, but accessing that from here in the model (where the validator is) is a big MVC no-no, and as such I don't think Rails gives me a way to do it. (I mean, I suppose I could stash a controller in some singleton somewhere or something, but... excuse me while I throw up.) What's the least ugly way to properly validate HAML in an ActiveRecord validator?

  • Rails: How to toggle a boolean field from a view?

    - by sscirrus
    Very simple question. I have a boolean field called "saved" in my database. I want to toggle this field by clicking on a text link that changes from "Save" to "Unsave" depending on the situation, and updates my "Customer" table with 0 or 1. I imagine Javascript may be a way to go for this but I am not experienced enough (yet!) in Javascript to know how to code it. What is the best way to approach this problem, and how can I find the code I would need to drop into my view to make this toggle work? Thank you very much.
