  • Where to put to_xls and from_xls in a rails app

    - by Joe Arasin
    So I have a model that I need to be able to serialize to/read from an Excel(XLS) document. I am a bit of a loss as to where this code actually belongs. My initial thought is that the to_xls is a view, but after poking around and seeing things like (to|from)_xml and (to|from)_json in ActiveRecord, I was wondering if maybe this stuff belonged in the model. Alternatively, does it belong in just a whole separate container somewhere? For what it's worth, users will be downloading models from the site, modifying them in excel, then posting them.

  • How can I override the attribute assignment in an active record object?

    - by ryeguy
    I know you can do this with virtual attributes, but what if the column actually exists? For example, my model has a raw_topic column. When raw_topic is set, I want artist and song_title to be set based off of raw_topic's contents. Ideally, I'd like to override the raw_topic= method, but rails doesn't seem to like that. What's the proper way of doing this? Is a callback the only way?

  • Passing arguments to an Rspec SpecTask

    - by Bayard Randel
    Rake allows for the following syntax: task :my_task, :arg1, :arg2 do |t, args| puts "Args were: #{args}" end I'd like to be able to do the same, but with RSpecs SpecTask. The following unfortunately fails: desc "Run example with argument" SpecTask.new('my_task'), :datafile do |t, args| t.spec_files = FileList['cvd*_spec.rb -datafile=#{args}'] t.spec_opts = ["-c -f specdoc"] end Is it possible to achieve this with a SpecTask, or is there an alternative approach?

  • Rails: Getting rid of generic "X is invalid" validation errors

    - by DJTripleThreat
    I have a sign-up form that has nested associations/attributes whatever you want to call them. My Hierarchy is this: class User < ActiveRecord::Base acts_as_authentic belongs_to :user_role, :polymorphic => true end class Customer < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end class Employee < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end I have some validation stuff in these classes as well. My problem is that if I try to create and Customer (or Employee etc) with a blank form I get all of the validation errors I should get plus some Generic ones like "User is invalid" and "Customer is invalid" If I iterate through the errors I get something like: user.login can't be blank User is invalid customer.whatever is blah blah blah...etc customer.some_other_error etc etc Since there is at least one invalid field in the nested User model, an extra "X is invalid" message is added to the list of errors. This gets confusing to my client and so I'm wondering if there is a quick way to do this instead of having to filer through the errors myself.

  • Rails and PostgreSQL: Role postgres does not exist

    - by Adam
    I have installed postgresql on my Mac OS Lion, and am working on a rails app. I use RVM to keep everything separate from my other rails apps. For some reason when I try to migrate the db for the first time rake cannot find the postgres user. I get the error FATAL: role "postgres" does not exist I have pgAdmin 3 so I can clearly see there is a postgres user in the DB - the admin account in fact - so I'm not sure what else to do. I read somewhere about people having issues with postgresql because of which path it was installed in, but then i don't think i would have gotten that far if it couldn't find the db. Any clues would be gratefully received! Thanks, Adam

  • Rails - Format number as currency format in the Getter

    - by daemonsy
    I am making a simple retail commerce solution, where there are prices in a few different models. These prices contribute to a total price. Imagine paying $0.30 more for selecting a topping for your yogurt. When I set the price field to t.decimal :price, precision:8, scale:2 The database stores 6.50 as 6.5. I know in the standard rails way, you call number_to_currency(price) to get the formatted value in the Views. I need to programmatically call the price field as well formatted string, i.e. $6.50 a few places that are not directly part of the View. Also, my needs are simple (no currency conversion etc), I prefer to have the price formatted universally in the model without repeated calling number_to_currency in views. Is there a good way I can modify my getter for price such that it always returns two decimal place with a dollar sign, i.e. $6.50 when it's called? Thanks in advance.

  • Rails - Help scoring an online quiz in RoR

    - by ChrisWesAllen
    I'm trying to grade a quiz application I would like to make. I have a questions model with and ask(the actual question), 4 choices(a-d), and a correct answer(string). In the view I have the 4 question being diplayed then the correct answer choice (This is just a test for functionality) and then I created a text_field to accept the users answer choice and a button to refresh the index action which has the scoring logic, for now.. --Do I need to put the text_field within a form_tag? <p>1. <%= h @question.q1 %></p> <p>2. <%= h @question.q2 %></p> <p>3. <%= h @question.q3 %></p> <p>4. <%= h @question.q4 %></p> <p>Answer: <%= h @question.correct %></p> <%= text_field_tag :choice, params[:choice] %> <%= button_to "Grade", {:controller => 'site', :action => "index"} %> <p> <%= @answer %></p> Heres the index controller action def index @question = Question.find(1) if @question.correct == params[:choice] @answer = 'right' else @answer = 'wrong' end end Its not really working. The textfield is supposed to take a letter choice like 'a' or 'c' and compare it with the correct answer in the database. I would love this to work by radiobuttons, but I'm a newbie to rails so I thought I'd take baby steps. So if anyone can help me with how to fix this by string, or preferably by radiobuttons, I'd really appreciate it.

  • Rails Multiple Table Inheritance question

    - by Tony
    I am starting to implement an MTI solution and have a basic question. I have 3 physical models - SMSNotifications, EmailNotifications, TwitterNotifications and they are subclasses of notification. At times in my code, I want to say Notifications.find(:all)so that I can get a set of results sorted by their creation time. Then I want to do things based on their subclass. What is the way to write Notifications.find(:all) and have Rails look through the subclass tables and combine the results? Right now Rails still thinks I have a physical Notifications table which goes against my MTI design. I am also considering the possibility that I should be using STI instead. I would probably have 10 empty columns per row but if getting all notifications requires a query for each type of notification, then I feel like this could be a big issue. Thanks!

  • How do I find the .max of an attribute value among a group of different Models?

    - by Angela
    Hi, everyone: I am also open to just straight-up refactoring what I'm finding to be pretty repetitive, but to give a baseline of how it's working.... I have for every contact a Campaign, which has_many of three types of Models: Email, Call, and Letter. When an Email (Call or Letter) has been executed for a specific contact, I have a Contact_Email(_or_Call_or_Letter) which belongs to both the Contact and the Model (Email_or_Call_or_Letter). Each Contact_Email for example pairing has a :date_sent attribute. So does each Contact_Call and Contact_Letter. How do I find the latest of all of them? Here is the code I wrote that can find the latest Email and my finding retyping similar code for Call and Letter, but then stuck on how to do a .max on all of them: def last_email(contact) #get campaign the contact belongs to @campaign = Campaign.find_by_id(contact.campaign_id) @last_email = ContactEmail.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") @last_call = ContactCall.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") @last_letter = ContactLetter.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") # how do I get the latest of all of these to display? if @last_sent_email.nil? return "no email sent" else return @last_sent_email.date_sent end end Question 1: With what I have, how can I find effectively @last_event given I can find the last Email, last Call, and last Letter for every contact? Question 2: How can I remove the repetitive code that I have to write for each Model?

  • How to :update after :success with link_to_remote Rails method?

    - by Kevin
    Hi, I'm trying to get two things done after a user clicks on a link: Delete a div Add another element at the bottom of the page I played with Rails link_to_remote and what I get with the code below is that the element is added before the div is deleted: <%= link_to_remote "&#x2713;", :url => { :controller => :movies, :action => :mark_as_seen, :movie => movie, :render => 'movie' }, :success => "Effect.Fade('movie_#{movie.id}_wrapper', { duration: 0.4 })", :update => "movies", :position => "bottom", :failure => "alert('Ooops! An error occurred.')" %> I tried to put :update and :position in a :complete callback, but nothing happened. And when I put both of them in the :success callback (after Effect.Fade), all I get is a parsing error. Any idea? Thanks, Kevin

  • 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 :(

  • Rails and jQuery - how do you get server-side validation errors to your view after an ajax request

    - by adam
    Ive searched this site but questions are usually regarding doing client-side validations or for different frameworks. I have a tasks list whose items can be edited inline. Upon submitting the inline edit form the item is updated all thanks to jQuery, ajax and rails. But I want to handle bad input from the user. HTML requests redisplay the view and errors are displayed thanks to rails helpers. But how do I insert that information after an ajax call? Heres my update method in my controller def update @task = Task.find(params[:id]) respond_to do |format| if @task.update_attributes(params[:task]) flash[:notice] = 'Task was successfully updated.' format.html { redirect_to(@task) } format.xml { head :ok } format.js else format.html { render :action => "edit" } format.xml { render :xml => @task.errors, :status => :unprocessable_entity } #format.js ...hmmm... either go to js.erb file or do stuff inline end end end

  • Saving an active record, in what order are the associated objects saved?

    - by Bryan
    In rails, when saving an active_record object, its associated objects will be saved as well. But has_one and has_many association have different order in saving objects. I have three simplified models: class Team < ActiveRecord::Base has_many :players has_one :coach end class Player < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end class Coach < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end I expected that when team.save is called, team should be saved before its associated coach and players. I use the following code to test these models: t = Team.new team.coach = Coach.new team.save! team.save! returns true. But in another test: t = Team.new team.players << Player.new team.save! team.save! gives the following error: > ActiveRecord::RecordInvalid: > Validation failed: Players is invalid I figured out that team.save! saves objects in the following order: 1) players, 2) team, and 3) coach. This is why I got the error: When a player is saved, team doesn't yet have a id, so validates_presence_of :team_id fails in player. Can someone explain to me why objects are saved in this order? This seems not logical to me.

  • Should I be using callbacks or should I override attributes?

    - by ryeguy
    What is the more "rails-like"? If I want to modify a model's property when it's set, should I do this: def url=(url) #remove session id self[:url] = url.split('?s=')[0] end or this? before_save do |record| #remove session id record.url = record.url.split('?s=')[0] end Is there any benefit for doing it one way or the other? If so, why? If not, which one is generally more common?

  • About to migrate :string but I'm thinking :text might be better. Performance/Purpose?

    - by Sam
    class CreateScrapes < ActiveRecord::Migration def self.up create_table :scrapes do |t| t.text :saved_characters t.text :sanitized_characters t.string :href t.timestamps end end def self.down drop_table :scrapes end end I'm about to rake db:migrate and I'm think about the attribute type if I should be using text or string. Since saved_characters and sanitized_characters will be arrays with thousands of unicode values, its basically comma delimited data, I'm not sure if `:text' is really the right way to go here. What would you do?

    I have a rails controller file that is too large (~900 lines - api_controller). I'd like to just split it up like something like this: api_controller.rb api_controller_item_admin.rb api_controller_web.rb I don't want to split into multiple controllers. What would be the preferred way to do this? Could I just require the new parts at the end? like: require './api_controller_item_admin' require './api_controller_web'

  • Decrease the load time for Mobile Version Rails Site

    - by Ramoji
    I have been working on the mobile version of my rails application.I am using the approach of using the same controller and rendering a mobile view when the request is from a mobile device. I am using jquery mobile in mobile views. For mobile views I did not use any layout for the views because it is the same as loading the required files in each view. In this approach, Every request essentially loads all of the required js,css files which i feel is making the mobile site to load slowly. How could i make my views to load the js and css files just once? Thanks, Ramoji.
