  • Encoding error PostgreSQL 8.4

    - by KandadaBoggu
    I am importing data from a CSV file. One of the fields has an accent(Telefónica O2 UK Limited). The application throws en error while inserting the data to the table. PGError: ERROR: invalid byte sequence for encoding "UTF8": 0xf36e6963 HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding". : INSERT INTO "companies" ("name", "validated") VALUES(E'Telef?nica O2 UK Limited', 't') How do I workaround this issue?

  • How do I reconnect to Memcache when forking in rails?

    - by Daniel Huckstep
    I have a rails 3 application, and a script called by rails runner. This script forks and does some stuff in other processes. I do the proper thing with ActiveRecord before forking, where I disconnect-fork-reconnect and all that jazz. My question is I also use memcache for the Rails.cache but should I be disconnecting-reconnecting that too for my forks? If so, how would I go about that in the rails way.

  • Unpacking gems [Rails 2.3.5]

    - by yuval
    I have the following gems defined in my environment.rb file: config.gem "authlogic" config.gem "paperclip" config.gem "pauldix-feedzirra", :lib => "feedzirra", :source => "http://gems.github.com" config.gem 'whenever', :lib => false, :source => 'http://gemcutter.org/' I have them installed on my local computer and everything is working well. Since I am working on a shared-server (DreamHost), I need to unpack those gems to get them to work (can't install them as I did on my own computer to get them to work). Before uploading, I ran the following on my local machine: rake gems:unpack This created the following folders in /vender/gems: authlogic-2.1.3, paperclip-2.3.1.1, pauldix-feedzirra-0.0.18, whenever-0.4.1 So it looks like they're all there. When I run rake db:migrate on the server, though, I get these following error: Missing these required gems: pauldix-feedzirra For some reason, the feedzirra unpacked gem is not detected. Could anybody give me a clue as to why this is happening and how to solve it? Thanks!

  • log analysis for rails

    - by deepak
    i have a rails app which makes heavy use of activeresource and httparty to make api calls. Is there any library/extension to log the requests and parse them, so that log analysis becomes easier and automated. RailsLogAnalyser is good but what about extra calls, what are the conventions? Something like a opensource/self-hosted alternative to newrelic, but with extensions to plug in your own logging.

  • Downsides to using FakeWeb compared to writing mocks for testing

    - by ajmurmann
    I never liked writing mocks and a while ago someone here recommended to use FakeWeb. I immediately fell completely in love with FakeWeb. However, I have to wonder if there is a downside to using FakeWeb. It seems like mocks are still much more common, so I wonder what I am missing that's wrong with using FakeWeb instead. Is there a certain kind of error you can't cover with Fakeweb or is it something about the TDD or BDD process?

  • Represent multiple Null/Generic objects in an ActiveRecord association?

    - by slothbear
    I have a Casefile model that belongs_to a Doctor. In additional to all the "real" doctors, there are several generic Doctors: "self-treated", "not specified", and "removed" (it used to have a real doctor, but no longer does). I suspect there will be even more generic values in the future. I started with special "doctors" in the database, generated from seed. The generic Doctors only need to respond to the "name" and "real_doctor?" methods. This worked with one, was strained with two, and now feels completely broken. I want to change the behavior and can't figure out how to test it, a bad sign. Creating all the generic objects for testing is also trouble, including fake values to pass validation of the required Doctor attributes. The Null Object pattern works well for one generic object. The "name" method could check casefile.doctor.nil? and return "self-treated", as demonstrated by Craig Ambrose. What pattern should I use when there are multiple generic objects with very limited state?

  • Merging Passed Parameters

    - by Josh Crowder
    I have a two data arrays sent in from a form, one called transloaded and the other video which is the actual form for the model.

  • Rails: Polymorphic User Table a good idea with AuthLogic?

    - by sscirrus
    Hi everyone, I have a system where I need to login three user types: customers, companies, and vendors from one login form on the home page. I have created one User table that works according to AuthLogic's example app at http://github.com/binarylogic/authlogic_example. I have added a field called "User Type" that currently contains either 'Customer', 'Company', or 'Vendor'. Note: each user type contains many disparate fields so I'm not sure if Single Table Inheritance is the best way to go (would welcome corrections if this conclusion is invalid). Is this a polymorphic association where each of the three types is 'tagged' with a User record? How should my models look so I have the right relationships between my User table and my user types Customer, Company, Vendor? Thanks very much!

  • Rails - Associations - Automatically setting an association_id for a model which has 2 belongs_to

    - by adam
    I have 3 models class User < ... belongs_to :language has_many :posts end class Post < ... belongs_to :user belongs_to :language end class Language < ... has_many :users has_many :posts end Im going to be creating lots of posts via users and at the same time I have to also specify the language the post was written in, which is always the language associatd with the user i.e. @user.posts.create(:text => "blah", :language_id => @user.language_id) That's fine but the way I set the language doesn't sit well with me. The language will always be that of the users so is there a 'best-practice' way of doing this? I know a little about callbacks and association extensions but not sure of any pitfalls.

  • Define a regex, which matches one digit twice and all others once

    - by Amin
    As part of a larger regex I would like to match the following restrictions: The string has 11 digits All digits are numbers Within the first 10 digits one number [0-9] (and one only!) must be listed twice This means the following should match: 12345678914 12235879600 Whereas these should not: 12345678903 -> none of the numbers at digits 1 to 10 appears twice 14427823482 -> one number appears more than twice 72349121762 -> two numbers appear twice I have tried to use a lookahead, but all I'm managing is that the regex counts a certain digit, i.e.: (?!.*0\1{2}) That does not do what I need. Is my query even possible with regex?

  • Remove a tag type from the view (involves alphabetical pagination)

    - by user284194
    I have an index view that lists all of the tags for my Entry and Message models. I would like to only show the tags for Entries in this view. I'm using acts-as-taggable-on.

  • ActiveRecord model with datetime stamp with timezone support attribute.

    - by jtarchie
    Rails is great that it will support timezone overall in the application with Time.zone. I need to be able to support the timezone a user selects for a record. The user will be able to select date, time, and timezone for the record and I would like all calculations to be done with respect to the user selected timezone. My question is what is the best practice to handle user selected timezones. The model is using a time_zone_select and datetime_select for two different attributes timezone and scheduled_at. When the model saves, the scheduled_at attribute gets converted to the locally defined Time.zone. When a user goes back to edit the scheduled_at attribute with the datetime_select the datetime is set to the converted Time.zone timezone and not the timezone attribute. Is there a nice way to handle to the conversion to the user selected timezone?

  • Warbler: Where are my images

    - by user108031
    I'm using Jruby and Warbler to deploy a Jruby on Rails application to a Tomcat server. I can see all of my images when I deploy the server with Webrick: jruby -S server/script. However, when I create a .war file out of the rails directory using jruby -S warble and deploy to Tomcat, none of my images show up on the tomcat server. I noticed that image location has changed to the root of the directory in the war file. It seems that /images/picturename.jpg would be appropriate, but my images are not showing up.

  • Multiple forms on a single page

    - by normalocity
    I've got an app that's in invite-only beta right now. Problem is, I can't get the invite system to work. :( On my root page there's a login form (which works just fine), and I'm trying to add a "request invite" form on the same page. I started doing it by putting the form for InviteRequest (ActiveRecord) inside a partial, in the "views" folder for "InviteRequest". The app is definitely calling this partial, but I'm getting the following error: NoMethodError in User_sessions#new Showing app/views/invite_request/_new.html.erb where line #2 raised: undefined method `invite_requests_path' for #<ActionView::Base:0x25b3248> Extracted source (around line #2): 1: <% @invite_request = InviteRequest.new() %> 2: <% form_for @invite_request do |ir| %> 3: <%= ir.label :email %> 4: <%= ir.text_field :email %> 5: <% end %> I also read through the "Multiple Models in a Form" section of my trusty copy of "Agile Web Development with Rails", about maybe doing this with a "fieldset" tag, but not sure if this is the right approach. Thx.

  • Rails I18n accepts_nested_attributes_for and error_messages_for

    - by Mike
    I've got two models class SurveyResponse has_many :answers, :class_name => SurveyResponseAnswer.name accepts_nested_attributes_for :answers end class SurveyResponseAnswer belongs_to :survey_response validates_presence_of :answer_text end In my nested form if validation fails I get this error displayed on the screen: "answers answer text can't be blank" I've customized my attribute names somewhat successfully using rails I18n. It doesn't behave exactly how I would expect though. The yml file below doesn't affect how the attribute name is printed in error_messages_for en: activerecord: models: survey_response: answers: "Response" But if from script/console I try SurveyResponse.human_attribute_name("answers") I get the expected result of "Response". What I'd like to do is have the validation error message say: "Response answer text can't be blank". Any ideas what I need to fix?

  • Rails: Convert HTML to PDF?

    - by rip747
    What is the best and easiest way of taking HTML and converting it into a PDF, similar to use CFDOCUMENT on ColdFusion? UPDATE: I really appreciate all the comments and suggestions that people have given so far, however I feel that people leaving their answers are missing the point. 1) the solution has to be free or open sourced. one person suggested using pricexml and the other pd4ml. both of these solutions costs money (pricexml costing an arm and a leg) which i'm not about the fork over. 2) they must be able to take in html (either from a file, url or a string variable) and then produce the pdf. libraries like prawn, rprf, rtex are produced using their own methods and not taking in html. please don't think i'm ungrateful for the suggestions, it's just that pdf generation seems like a really problem for people like me who use ColdFusion but want to convert to Rails.

  • How do I set a time in a time_select view helper?

    - by brad
    I have a time_select in which I am trying to set a time value as follows; <%= f.time_select :start_time, :value => (@invoice.start_time ? @invoice.start_time : Time.now) %> This always produces a time selector with the current time rather than the value for @invoice.start_time. @invoice.start_time is in fact a datetime object but this is passed to the time selector just fine if I use <%= f.time_select :start_time %> I guess what I'm really asking is how to use the :value option with the time_select helper. Attempts like the following don't seem to produce the desired result; <%= f.time_select :start_time, :value => (Time.now + 2.hours) %> <%= f.time_select :start_time, :value => "14:30" %>

  • RESTful design, how to name pages outside CRUD et al?

    - by sscirrus
    Hi all, I'm working on a site that has quite a few pages that fall outside my limited understanding of RESTful design, which is essentially: Create, Read, Update, Delete, Show, List Here's the question: what is a good system for labeling actions/routes when a page doesn't neatly fall into CRUD/show/list? Some of my pages have info about multiple tables at once. I am building a site that gives some customers a 'home base' after they log on. It does NOT give them any information about themselves so it shouldn't be, for example, /customers/show/1. It does have information about companies, but there are other pages on the site that do that differently. What do you do when you have these situations? This 'home-base' is shown to customers and it mainly has info about companies (but not uniquely so). Second case: I have a table called 'Matchings' in between customers and companies. These matchings are accessed in completely different ways on different parts of the site (different layouts, different CSS sheets, different types of users accessing them, etc. They can't ALL be matchings/show. What's the best way to label the others? Thanks very much. =)

  • Arbitrary attributes error with has_one association and Factory Girl

    - by purpletonic
    I'm trying to build a basic shopping cart for a Rails app I'm working on. Nothing special, - the shopping cart has many line_items - each line_item has_one product associated and a quantity with it class Cart < ActiveRecord::Base attr_accessible :line_items has_many :line_items, :dependent => :destroy end class LineItem < ActiveRecord::Base attr_accessible :quantity, :product belongs_to :cart has_one :product end I'm trying to use RSpec to test this association, but i'm doing something wrong as I'm getting an error that says: DEPRECATION WARNING: You're trying to create an attribute 'line_item_id'. Writing arbitrary attributes on a model is deprecated, and I'm not sure why. In my factories.rb file I'm defining the line_item factory as follows: factory :line_item do quantity { Random.rand(1..5) } product end factory :cart do factory :cart_with_two_line_items do ignore do line_item_count 2 end after(:create) do |cart, evaluator| FactoryGirl.create_list(:line_item, evaluator.line_item_count, cart_id: cart) end end end Any pointers where I'm going wrong, it's probably something basic, but I'm still quite new to Rspec. Thanks in advance.

  • Deploying a Rails App to Multiple Servers using Capistrano - Best Practices

    - by Louise
    I have a rails application that I need to deploy to 3 servers - machine1.com, machine2.com and machine3.com. I want to be able to deploy it to all machines at once and each machine individually. Can someone help me out with a skeleton Capistrano config file / recipe? Should it all be in deploy.rb or should I break it out in machine1.rb, etc? I thought I was on the right track getting Capistrano to take in command line arguments, but it choked when I tried set the roles within the namespaces. I'd pass in 'hosts=1,2,3' as an argument and set the role:app/web/db to "machine#{host}.com" after splitting on the command and going into an each do |host| {}... Anyway, other than creating 4 different deploy.rb files and renaming it before running cap:deploy each time, I'm stumped. I'd like to be able to do the following: cap deploy:machine1:latest_version_from_svn cap deploy:all_machines:latest:version_from_svn Just don't know if it should all be in deploy.rb split up with namespaces or if it should be broken into multiple deploy*.rb files.

  • Factory Girl sequence fails under autospec

    I have this Factory: Factory.define :email_address do |e| e.sequence(:address) { |n| "factory_#{n}@example.com" } e.validated true end When I run my specs with rake spec, it works fine. When I run autospec, it fails right away, claiming that the email address is being used twice in two different objects (there is a validation which restricts this). Why is it behaving differently under autospec? Thanks, John
