  • How to rename model

    - by samuil
    I made a mistake early in development, and named one of my models with plural noun (Users instead of User). Is there an easy way to rename it and corresponding controller (similar to generating it with script/generate way)?

  • MongoDB architectural question

    - by pex
    I have to store 4 Models. Let's say a Post that has many and belongs to many Categories. Category on the other hand has many Qualities. At the moment I'm of the opinion, that Post and Categories are Documents. Qualities becomes an EmbeddedDocument of Categories. We're coming to the root problem: There are a lot of Votes on Qualities that belong to a Post. I thought about embed Votes in Post and give it a quality_id. I am really expecting a lot of Votes and there has to be a possibility to filter them (e.g by Username / Usergroup / Date voted). I worked with MongoMapper and I think the missing existence of find methods for EmbeddedDocuments could become a killer. On the other hand I'm wondering about performance issues. What if I want to provide a Post without all the Votes, but only a few. Or, what if I define an own Document for Votes and have tons of Vote-Documents? Wouldn't that become a performance killer?

  • Simple cropping with Paperclip

    - by collimarco
    I would like to crop images on upload using Paperclip to get square thumbs from the center of the original picture. I find out a method in documentation that seems to do exactly what I want: transformation_to(dst, crop = false) The problem is that I can't figure out where to use this method. It would be great to simply pass something as a parameter here: has_attached_file :picture, :styles = { :medium = "600x600", :thumb = "something here" }

  • Base-camp Style Subdomains and IDs of Models

    - by Newy
    I have an app that has Basecamp-style subdomains, that is, I have Projects, Users, Apples and Oranges. The Users, Apples and Oranges are all keyed to a Project and only exist in the http://project.myapp.com. I added a project_id to Users, Apples and Oranges and everything works, except of course that the ids of those three objects increment globally, and throughout my app I lookup objects by that id. This doesn't seem like best practice. Should I instead do lookups by a secondary key? How does that affect efficiency? If there's a good blog post that covers this, would be wesome.

In short : I know of google apps, authSMTP, sendGrid, mailChimp..but I was wondering if there is something simple I can use

  • How to deal with array of checkbox values in Ruby 1.9.1?

    - by Ola Tuvesson
    In Ruby 1.9.1 strings are no longer enumerable and string.each is undefined. This causes a problem when parsing values for an array of generated checkboxes since the field value, when submitted, becomes an array of strings. For example: <% for map in Map.find(:all) %> <%= check_box_tag "listing[map_ids][]", map.id %> <%= map.title %> <% end %> This will result in an error, undefined method `each' for "1":String, in process_parameter_filter because map_ids is being passed as "map_ids"=["1","2"] (if checkboxes with values 1 and 2 have been checked that is). What is the recommended way to fix this?

  • Custom array class with assotiated objects

    - by FancyDancy
    I have a simple structure, it's just an array of model's objects. For example, it's a users with books. @books = Book.find(:all, :include = :users) I need to check, does user have a book? I have written a helper method: def has_book?(user_id) @books.select{|b| b.user_id == user_id}.any? end Then, i need to get only books from selected library def in_library(n) @books.select{|b| b.library == n} end I have tried to make custom Array class: class BooksList < Array def initialize(books) self << books end # its my custom methods def has_book?(user_id) self.select{|b| b.user_id == user_id}.any? end def in_library(n) self.select{|b| b.library == n} end end It works, but i have only one problem. I can't access Book's assotiated object (user). So i can't write: @books = BookList.new(Book.find(:all, :include => :users)) @books.first.user.id # it says undefined method `user' for #<Array:0x104b43e08>

  • How do I display two different objects in a search?

    - by JZ
    github url I am using a simple search that displays search results: @adds = Add.search(params[:search]) In addition to the search results I'm trying to utilize a method, nearbys(), which displays objects that are close in proximity to the search result. The following method displays objects which are close to 2, but it does not display object 2. How do I display object 2 in conjunction with the nearby objects? @adds = Add.find(2).nearbys(10) While the above code functions, when I use search, @adds = Add.search(params[:search]).nearbys(10) a no method error is returned, undefined methodnearbys' for Array:0x30c3278` How can I search the model for an object AND use the nearbys() method AND display all results returned? Model: def self.search(search) if search find(:all, :conditions => ['address LIKE ?', "%#{search}%"]) # where('address LIKE ?', "%#{search}") else find(:all) end end

  • Problem updating a database field from my controller

    - by ben
    I have an update method in my users controller that I call from a HTTPService in Flex 4. The update method is as follows: def updateName @user = User.find_by_email(params[:email]) @user.name = params[:nameNew] render :nothing => true end This is console output: Processing UsersController#updateName (for 127.0.0.1 at 2010-05-24 14:12:49) [POST] Parameters: {"action"="updateName", "nameNew"="ben", "controller"="users", "email"="[email protected]"} User Load (0.6ms) SELECT * FROM "users" WHERE ("users"."email" = '[email protected]') LIMIT 1 Completed in 20ms (View: 1, DB: 1) | 200 OK [http://localhost/users/updateName] But when I check my database, the name field is never updated. What am I doing wrong? Thanks for reading.

  • How Do I Loop Through a Date Range in Reverse?

    - by Russ Bradberry
    I have a date range that I would like to be able to loop through in reverse. Give the following, how would I accomplish this, the standard Range operator doesn't seem t be working properly. >> sd = Date.parse('2010-03-01') => Mon, 01 Mar 2010 >> ed = Date.parse('2010-03-05') => Fri, 05 Mar 2010 >> (sd..ed).to_a => [Mon, 01 Mar 2010, Tue, 02 Mar 2010, Wed, 03 Mar 2010, Thu, 04 Mar 2010, Fri, 05 Mar 2010] >> (ed..sd).to_a => [] as you can see, the range operator works properly form start to end, but not from end to start.

  • 'sript/console test' with spork and rspec not loading the whole environment?

    - by TheDeeno
    I'm trying to load up console to interact with some of my rspec mocking helpers. I expected that running script/console test would load an env similar to when I run spec. However, this doesn't appear to be the case. It looks like spec_helper is never loaded. Or, if it is, it's not actually running through the logic because spork has polluted it a bit. In short, is there a quick and easy way to get an interactive rspec party going?

  • ActionMailer execution timeout

    - by user275729
    When trying to send an email to the user for reseting their password, I keep getting an execution timed out error. Other mailer functions work, so I know that the config settings are correct. The header reads: "Timeout::Error in Password resetsController#create" Here is the password_resets_controller: def create @user = User.find_by_email(params[:email]) if @user User.deliver_password_reset_instructions(@user.id) flash[:notice] = "Instructions to reset your password have been emailed to you. " + "Please check your email." redirect_to '/' else flash[:notice] = "No user was found with that email address" render :action => :new end end Here is the method inside of User.rb def self.deliver_password_reset_instructions(user_id) user = User.find(user_id) user.reset_perishable_token! Emailer.deliver_password_reset_instructions(user) end Finally, here is the actual method inside of emailer.rb: default_url_options[:host] = "http://0.0.0.0:3000" #development def password_reset_instructions(user) @subject = "FanGamb Password Reset" @from = '[email protected]' @recipients = user.email @sent_on = Time.now @body["edit_password_reset_url"] = edit_password_reset_url(user.perishable_token) @headers["X-SMTPAPI"] = "{\"category\" : \"Password Recovery\"}"#send grid category header end Why is "Password" in the error message referred to causing a timeout::error

  • Cap deploy doesn't work all the sudden; something to do with FactoryGirl and assets

    - by Jason Swett
    I've been cap deploying my app all throughout it development, and this last time I tried to deploy it, it didn't work. Here's what happened: * executing `deploy:assets:precompile' * executing "cd /var/www/oneteam/releases/20121006153136 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile" servers: ["electricsasquatch.com"] [electricsasquatch.com] executing command ** [out :: electricsasquatch.com] rake aborted! ** [out :: electricsasquatch.com] uninitialized constant OneTeam::Application::FactoryGirl ** [out :: electricsasquatch.com] ** [out :: electricsasquatch.com] (See full trace by running task with --trace) It looks like it failed on the deploy:assets:precompile command. I don't get why that command would have tried to do anything with FactoryGirl, though. Any ideas?

  • Sanitizing input for display in view when using simple_format

    - by Eric
    Hi, I'm trying to figure out the right way to display comments such that newlines and links are displayed. I know that usually, you should display user-inputs only when escaping html with h(). That of course won't display newlines or links, so I found the simple_format and auto_link methods. What I am now doing is: simple_format(santize(auto_link(comment.text))) Is this the right way to do this, and is it still safe from XSS attacks? Thanks! Eric
