  • Reloading Rails Directories: Not Lib!

    - by yar
    I have checked out several questions on this, including all of those you see next to the question. Unfortunately, I'm not working with a plugin, and I don't want to work in lib. I have a directory called File.join(Rails.root, 'classes') and I'd like the classes in this directory to reload automatically in dev. In my environment.rb I have this line config.load_paths << File.join(Rails.root, 'classes') which works fine and blows up if the path isn't there. The reloading line in my development.rb also works fine require_dependency File.join(Rails.root, 'classes', 'blah.rb') which blows up if the file is not there (a good sign). However, the file doesn't reload. This all works if the file is in the root of lib and I use the require_dependency line, but my whole point is to get stuff out of lib as suggested here.

  • Resque: Slow worker startup and Forking

    - by David John
    I'm currently moving my application from a Linode setup to EC2. Redis is currently installed on a remote instance with various worker instances interacting with the queue. Thats all going fantastic. My problem is with the amount of time it takes for a worker to be 'instantiated' and slow forking. Starting a worker will usually take between 30 seconds and a minute(from god.rb starting the worker rake task and the worker actively starting work on the queue). I could live with that, but I've not experienced such a wait time on my current Linode production box so I believe its one of my symptoms to a bigger problem. Next issue is that jobs that took a second or less in my previous environment now seem to take about 5 to 10 times longer.. I'm assuming this must be some sort of issue with my Ubuntu install on EC2? One notable difference is that I'm running REE 1.8.7-2010.01 in my new setup, and REE 1.8.6 on the old Linode boxes. Anyone else experienced these issues?

  • Rails, Edit page update in a window

    - by Mike
    I have my code working so that I have a table of businesses. There's a pencil icon you can click on the edit the business information. The edit information comes up in a partial inside of a modal pop up box. The only problem is that once they make the changes they want and click update, it sends them to the 'show' page for that business. What I want to happen is have the pop up box close and have it update the information. This is my update function in my controller. def update @business = Business.find(params[:id]) respond_to do |format| if @business.update_attributes(params[:business]) flash[:notice] = 'Business was successfully updated.' format.html { redirect_to(business_url(@business)) } format.js else format.html { render :action => "edit" } format.xml { render :xml => @business.errors, :status => :unprocessable_entity } end end end I tried following railscast 43 and i created an .rjs file but I couldn't get that to work at all. My update was still taking me to the show page. Any help would be appreciated. EDIT: Added some more code. <% form_for(@business) do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> ... <%= f.label :business_category %><br /> <%= f.select :business_category_id, @business_categories_map, :selected => @business.business_category_id %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> This is my form inside of my edit page which is being called through the index in a pop up by: <div id="popupEdit<%=h business.id %>" class="popupContact"> <a class="popupClose<%=h business.id %>" id="popupClose">x</a> <% if business.business_category_id %> <% @business = business %> <%= render "business/edit" %> <% end %> </div>

  • What to Learn: Rails 1.2.4 -> Rails 3

    - by Saterus
    I've recently convinced my management that our outdated version of Rails is slowing us down enough to warrant an upgrade. The approach we're taking is to start a fresh project with current technology rather than a painful upgrade. Our requirements for the project have changed and this will be much easier. The biggest problem is actually that my knowledge of Rails is out of date. I've dealt only with Rails 1.2.4 while the rest of the world has moved on long ago. What topics have I missed by being buried in my work instead of keeping up with the current Rails fashion? I'm hesitant to dig through blogs at random because I'm not sure how much has changed between the intervening versions of Rails. It's no use to learn Rails 2.1-2.3 specific stuff that is no longer useful for Rails 3.

  • Adding RESTful route to Rails app

    - by macek
    I'm reading these two pages resources Adding more RESTful actions The Rails Guides page shows map.resources :photos, :new => { :upload => :post } And its corresponding URL /photos/upload This looks wonderful. My routes.rb shows this map.resources :users, :new => { :signup => :get, :register => :post } When I do: [~/my_app]$ rake routes I see the two new routes added signup_new_user GET /users/new/signup(.:format) register_new_user POST /users/new/register(.:format) Note the inclusion of /new! I don't want that. I just want /users/signup and /users/register (as described in the Rails Routing Guide). Any help?

(like post_comments_path) Any ideas?

  • Can't mass-assign protected attributes -- unsolved issue

    - by nfriend21
    I have read about 10 different posts here about this problem, and I have tried every single one and the error will not go away. So here goes: I am trying to have a nested form on my users/new page, where it accepts user-attributes and also company-attributes. When you submit the form: Here's what my error message reads: ActiveModel::MassAssignmentSecurity::Error in UsersController#create Can't mass-assign protected attributes: companies app/controllers/users_controller.rb:12:in `create' Here's the code for my form: <%= form_for @user do |f| %> <%= render 'shared/error_messages', object: f.object %> <%= f.fields_for :companies do |c| %> <%= c.label :name, "Company Name"%> <%= c.text_field :name %> <% end %> <%= f.label :name %> <%= f.text_field :name %> <%= f.label :email %> <%= f.text_field :email %> <%= f.label :password %> <%= f.password_field :password %> <%= f.label :password_confirmation %> <%= f.password_field :password_confirmation %> <br> <% if current_page?(signup_path) %> <%= f.submit "Sign Up", class: "btn btn-large btn-primary" %> Or, <%= link_to "Login", login_path %> <% else %> <%= f.submit "Update User", class: "btn btn-large btn-primary" %> <% end %> <% end %> Users Controller: class UsersController < ApplicationController def index @user = User.all end def new @user = User.new end def create @user = User.create(params[:user]) if @user.save session[:user_id] = @user.id #once user account has been created, a session is not automatically created.

  • Rails and SWFUpload: Sporadic Failure on Upload and Response Issue

    - by Gimli
    I've got SWFUpload version 2.5 beta 3 attached to my Rails 2.3.2 application and it works great 75% of the time. The other 25%, I get types of failure. The first failure is a failure to upload. The activity starts, but never actually sends the file to the servers. In my JS, when setting breakpoints, it stops between setting the post params and starting the upload (last two lines below): var params = { "authenticity_token": authToken, "photo[name]": $("#photo_name").val(), "photo[description]": $("#photo_description").val(), "photo[post_id]": $("#post_id").val() }; params[keyName] = key; swfu.setPostParams(params); swfu.startUpload(); It just occurred to me that the file might not being queued, but I've got a handler attached to show the file name in a text box and that works consistently. The second issue is this: Sometimes the response string is truncated. I'm rendering a partial in Rails without a layout to show the uploaded file data in my layout. Most of the time this partial comes through fine, but sometimes it comes through as only the first line, or only parts of the first several lines. The variables seem to be coming through into the view just fine. Any ideas? Thanks!

  • Cannot render javascript from controller

    - by Ermin
    I want to display a modal window with an error message, when the user has entered something invalid in a form, but render another action if everything is ok. However, when I try to display the modal window with render :js => "jQuery.facebox(#{...})" only the actual javascript called is displayed: try { jQuery.facebox(...) } catch (e) { alert('RJS error:\n\n' + e.toString()); alert('jQuery.facebox(\"<div class=\'error\'>Error</div>\")'); throw e }

  • 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?

  • Rails page caching and flash messages

    - by KJF
    I'm pretty sure I can page cache the vast majority of my site but the one thing preventing me from doing so is that my flash messages will not show, or they'll show at the wrong time. One thing I'm considering is writing the flash message to a cookie, reading it and displaying it via javascript and clearing the cookie once the message has been displayed. Has anyone had any success doing this or are there better methods? Thanks.

  • active record relations – who needs it?

    - by M2_
    Well, I`m confused about rails queries. For example: Affiche belongs_to :place Place has_many :affiches We can do this now: @affiches = Affiche.all( :joins => :place ) or @affiches = Affiche.all( :include => :place ) and we will get a lot of extra SELECTs, if there are many affiches: Place Load (0.2ms) SELECT "places".* FROM "places" WHERE "places"."id" = 3 LIMIT 1 Place Load (0.3ms) SELECT "places".* FROM "places" WHERE "places"."id" = 3 LIMIT 1 Place Load (0.8ms) SELECT "places".* FROM "places" WHERE "places"."id" = 444 LIMIT 1 Place Load (1.0ms) SELECT "places".* FROM "places" WHERE "places"."id" = 222 LIMIT 1 ...and so on... And (sic!) with :joins used every SELECT is doubled! Technically we cloud just write like this: @affiches = Affiche.all( ) and the result is totally the same! (Because we have relations declared). The wayout of keeping all data in one query is removing the relations and writing a big string with "LEFT OUTER JOIN", but still there is a problem of grouping data in multy-dimentional array and a problem of similar column names, such as id. What is done wrong? Or what am I doing wrong? UPDATE: Well, i have that string Place Load (2.5ms) SELECT "places".* FROM "places" WHERE ("places"."id" IN (3,444,222,57,663,32,154,20)) and a list of selects one by one id. Strange, but I get these separate selects when I`m doing this in each scope: <%= link_to a.place.name, **a.place**( :id => a.place.friendly_id ) %> the marked a.place is the spot, that produces these extra queries.

  • How to perform Rails model validation checks within model but outside of filters using ledermann-rails-settings and extensions

    - by user1277160
    Background I'm using ledermann-rails-settings (https://github.com/ledermann/rails-settings) on a Rails 2/3 project to extend virtually the model with certain attributes that don't necessarily need to be placed into the DB in a wide table and it's working out swimmingly for our needs. An additional reason I chose this Gem is because of the post How to create a form for the rails-settings plugin which ties ledermann-rails-settings more closely to the model for the purpose of clean form_for usage for administrator GUI support. It's a perfect solution for addressing form_for support although... Something that I'm running into now though is properly validating the dynamic getters/setters before being passed to the ledermann-rails-settings module. At the moment they are saved immediately, regardless if the model validation has actually fired - I can see through script/console that validation errors are being raised. Example For instance I would like to validate that the attribute :foo is within the range of 0..100 for decimal usage (or even a regex). I've found that with the previous post that I can use standard Rails validators (surprise, surprise) but I want to halt on actually saving any values until those are addressed - ensure that the user of the GUI has given 61.43 as a numerical value. The following code has been borrowed from the quoted post. class User < ActiveRecord::Base has_settings validates_inclusion_of :foo, :in => 0..100 def self.settings_attr_accessor(*args) >>SOME SORT OF UNLESS MODEL.VALID? CHECK HERE args.each do |method_name| eval " def #{method_name} self.settings.send(:#{method_name}) end def #{method_name}=(value) self.settings.send(:#{method_name}=, value) end " end >>END UNLESS end settings_attr_accessor :foo end Anyone have any thoughts here on pulling the state of the model at this point outside of having to put this into a before filter? The goal here is to be able to use the standard validations and avoid rolling custom validation checks for each new settings_attr_accessor that is added. Thanks!

  • 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?

  • Rails - default value in text_field but only for new_record?

    - by jyoseph
    On a Content model have an attribute named slug. When creating a new record, I want to use a helper to populate this field, but on an existing record I want to use the value from the database. Currently I have: <%- if @content.new_record? -%> <%= f.text_field :slug, :value => "#{generate_slug(6)}" %> <%- else %> <%= f.text_field :slug %> <%- end %> But that seems a bit verbose. Is this the best way, or is there no other way? (Rails newb just trying to find the "Rails way" on issues I'm unsure of) Edit I should note that the helper is currently in /app/helpers/application_helper.rb

  • How do you prevent Git from printing 'remote:' on each line of the output of a post-recieve hook?

  • Getting the first of a GROUP BY clause in SQL

    - by Michael Bleigh
    I'm trying to implement single-column regionalization for a Rails application and I'm running into some major headaches with a complex SQL need. For this system, a region can be represented by a country code (e.g. us) a continent code that is uppercase (e.g. NA) or it can be NULL indicating the "default" information. I need to group these items by some relevant information such as a foreign key (we'll call it external_id). Given a country and its continent, I need to be able to select only the most specific region available. So if records exist with the country code, I select them. If, not I want a records with the continent code. If not that, I want records with a NULL code so I can receive the default values. So far I've figured that I may be able to use a generated CASE statement to get an arbitrary sort order. Something like this: SELECT *, CASE region WHEN 'us' THEN 1 WHEN 'NA' THEN 2 ELSE 3 END AS region_sort FROM my_table WHERE region IN ('us','NA') OR region IS NULL GROUP BY external_id ORDER BY region_sort The problem is that without an aggregate function the actual data returned by the GROUP BY for a given row seems to be untameable. How can I massage this query to make it return only the first record of the region_sort ordered groups?
