  • Include params/request information in Rails logger?

    - by Dan Hill
    Hi everyone, I'm trying to get some more information into my Rails logs, specifically the requested URI or current params, if available (and I appreciate that they won't always be). However I just don't seem able to. Here's what I've done so far: #config/environments/production.rb config.logger = Logger.new(config.log_path) config.log_level = :error config.logger.level = Logger::ERROR #config/environment.rb class Logger def format_message(level, time, progname, msg) "**********************************************************************\n#{level} #{time.to_s(:db)} -- #{msg}\n" end end So I can customize the message fine, yet I don't seem to be able to access the params/request variables here. Does anyone know if this is possible, and if so how? Or if there's a better way to get this information? (Perhaps even something Redis based?) Thanks loads, Dan

  • Test (with RSpec) a controller outside of a Rails environment

    - by ramon.tayag
    I'm creating a gem that will generate a controller for the Rails app that will use it. It's been a trial and error process for me when trying to test a controller. When testing models, it's been pretty easy, but when testing controllers, ActionController::TestUnit is not included (as described here). I've tried requiring it, and all similar sounding stuff in Rails but it hasn't worked. What would I need to require in the spec_helper to get the test to work? Thanks!

  • How Do I Prevent Rails From Treating Updated Nested Attributes Differently From New Nested Attribute

    - by James
    I am using rails3 beta3 and couchdb via couchrest. I am not using active record. I want to add multiple "Sections" to a "Guide" and add and remove sections dynamically via a little javascript. I have looked at all the screencasts by Ryan Bates and they have helped immensely. The only difference is that I want to save all the sections as an array of sections instead of individual sections. Basically like this: "sections" => [{"title" => "Foo1", "content" => "Bar1"}, {"title" => "Foo2", "content" => "Bar2"}] So, basically I need the params hash to look like that when the form is submitted. When I create my form I am doing the following: <%= form_for @guide, :url => { :action => "create" } do |f| %> <%= render :partial => 'section', :collection => @guide.sections %> <%= f.submit "Save" %> <% end %> And my section partial looks like this: <%= fields_for "sections[]", section do |guide_section_form| %> <%= guide_section_form.text_field :section_title %> <%= guide_section_form.text_area :content, :rows => 3 %> <% end %> Ok, so when I create the guide with sections, it is working perfectly as I would like. The params hash is giving me a sections array just like I would want. The problem comes when I want edit guide/sections and save them again because rails is inserting the id of the guide in the id and name of each form field, which is screwing up the params hash on form submission. Just to be clear, here is the raw form output for a new resource: <input type="text" size="30" name="sections[][section_title]" id="sections__section_title"> <textarea rows="3" name="sections[][content]" id="sections__content" cols="40"></textarea> And here is what it looks like when editing an existing resource: <input type="text" value="Foo1" size="30" name="sections[cd2f2759895b5ae6cb7946def0b321f1][section_title]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_section_title"> <textarea rows="3" name="sections[cd2f2759895b5ae6cb7946def0b321f1][content]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_content" cols="40">Bar1</textarea> How do I force rails to always use the new resource behavior and not automatically add the id to the name and value. Do I have to create a custom form builder? Is there some other trick I can do to prevent rails from putting the id of the guide in there? I have tried a bunch of stuff and nothing is working. Thanks in advance!

  • How can I prevent Rails from "pluralizing" a column name?

    - by Mike
    I'm using dwilkie's foreigner plugin for rails. I have a table creation statement that looks like: create_table "agents_games", :force => true, :id => false do |t| t.references :agents, :column => :agent_id, :foreign_key => true, :null => false t.references :games, :column => :game_id, :foreign_key => true, :null => false end However, this generates the following SQL: [4;35;1mSQL (2.7ms)[0m [0mCREATE TABLE "agents_games" ("agents_id" integer NOT NULL, "games_id" integer NOT NULL) [0m I want the columns to be called agent_id and game_id - not agents_id and agent_id. How can I prevent Rails from pluralizing the columns? I tried the following in my enviornment.rb file, which didn't help: ActiveSupport::Inflector.inflections do |inflect| inflect.uncountable "agent_id", "game_id" end

  • Render public html's for dynamic banners in Rails ?

    - by benoror
    Hi, I would like to render specific HTML snippets for displaying banners, because each banner has a different nature (some images, some flash, etc). Every banner file is under app/public/banners/. I tried many ways, like: render :file => "/banners/somebanner.html" But it can't locate the file, because rails looks under app/views. Any Ideas ? Thanks! Missing template banners/somebanner.html in view path app/views

  • Rails & ActiveRecord: Appending methods to models that inherit from ActiveRecord::Base

    - by PlankTon
    I have a standard ActiveRecord model with the following: class MyModel < ActiveRecord::Base custom_method :first_field, :second_field end At the moment, that custom_method is picked up by a module sent to ActiveRecord::Base. The functionality basically works, but of course, it attaches itself to every model class, not just MyModel. So if I have MyModel and MyOtherModel in the same action, it'll assume MyOtherModel has custom_method :first_field, :second_field as well. So, my question is: How do I attach a method (eg: def custom_method(*args)) to every class that inherits from ActiveRecord::Base, but not by attaching it to ActiveRecord::Base itself? Any ideas appreciated.

  • Paperclip wont save image in rails app

    - by Micke
    Hello stackoverflow. I am trying to use Paperclip with my rails app to add an avatar to a user but it wont save my image when creating the user. This is what the model looks like: class User < ActiveRecord::Base has_attached_file :avatar And the registerform in haml: - form_for :user, @user, :url => { :action => "signup" }, :html => { :multipart => true } do |f| ... ... %li %div{:class => "header"} Profilepicture %div{:class => "input"} = f.file_field :avatar And when i look in the log this is what is being passet to the "signup" action: Parameters: {"commit"=>"Save", "action"=>"signup", "controller"=>"user/register", "user"=>{"name"=>"Micke Lisinge", "birthmonth"=>"07", "password_confirmation"=>"[FILTERED]", "nickname"=>"lisinge", "avatar"=>#<File:/tmp/RackMultipart20100426-3076-1x04oxy-0>, "gen"=>"m", "birthday"=>"23", "password"=>"[FILTERED]", "birthyear"=>"1992", "email"=>"[email protected]"}} [paperclip] Saving attachments. Paperclip says it is saving the template but when i look in the public folder in my app it has created a system but the system folder is empty. So it seems like it isnt saving the picture to the folder. It gets handled by the form and saved in my /tmp folder. Maybe you guys have any tips or know what this problem might be? Thanks in advance, Micke.

  • Rails 2 support after Rails 3 has been released

    - by J. Pablo Fernández
    Is there some plan or estimate about how long will Rails 2 be supported after Rails 3 has been released? I wanted to ride the wave and move to Rails 3 right away, specially for projects that may take 4 or 6 months to finish (so that they would probably be released with Rails 3.0.0 final) but I've found many things still not working, many basic plugins and gems; so I believe I'm stuck with Rails 2 for now.

And i want to validate birthyear like this: validates_inclusion_of :birthyear, :in => Date.today.year-50..Date.today.year-12 So the user can be at least 12 years but at most 50 years when they are registering. But my problem is that the variable from the input is a string and not an integer. So how can i convert the input to an integer? or is there any easier way to check the users age? Thanks, Micke

  • building a backend for generating webquests with rails

    - by buk
    hello, i want to learn rails and as a project to learn rails i came across webquests. what a webquest is is clearly written here1 and this is a example how a webquest look like. i started with script/generate nifty_scaffold introduction index and repeat this for every section like task , Process, Evaluation and so on. but i dont think thats the right way because i have a lot of code for the same thing. on the other side i am more flexible on designing views or controllers instead of having only one controller foer all pages. i am not asking here to get code. i am asking who to "build" such a backend where you can click on "New Webquest" a form comes up and you can enter all the text who belongs to the topic. maybee i can add some drawings later. i hope anyone can show me how to do that. or post me some links or some rtfms :D regards, buk

  • Testing Paypal error messages using ActiveMerchant

    - by vrish88
    Hello, Is there a way to test your application's processing and handling of Paypal generated credit card errors? I'd like to verify that my application can handle a declined credit card or something like that. So is there a way to have Paypal send an error message? Or would it be better to generate a stub and use it in the testing environment? If this is the better way, how would one generate a stub? Thanks!

  • How to avoid saving a blank model which attributes can be blank

    - by auralbee
    Hello people, I have two models with a HABTM association, let´s say book and author. class Book has_and_belongs_to_many :authors end class Author has_and_belongs_to_many :books end The author has a set of attributes (e.g. first-name,last-name,age) that can all be blank (see validation). validates_length_of :first_name, :maximum => 255, :allow_blank => true, :allow_nil => false In the books_controller, I do the following to append all authors to a book in one step: @book = Book.new(params[:book]) @book.authors.build(params[:book][:authors].values) My question: What would be the easiest way to avoid the saving of authors which fields are all blank to prevent too much "noise" in the database? At the moment, I do the following: validate :must_have_some_data def must_have_some_data empty = true hash = self.attributes hash.delete("created_at") hash.delete("updated_at") hash.each_value do |value| empty = false if value.present? end if (empty) errors.add_to_base("Fields do not contain any data.") end end Maybe there is an more elegant, Rails-like way to do that. Thanks.

  • How to get an array from a database in Rails3 even when there's only one record?

    - by yuval
    In Rails3, I have the following line: @messages = Message.where("recipient_deleted = ?", false).find_by_recipient_id(@user.id) In my view, I loop through @messages and print out each message, as such: <% for message in @messages %> <%= message.sender_id %> <%= message.created_at %> <%= message.body %> <% end %> This works flawlessly when there are several messages. The problem is that when I have one message, I get an error thrown at me: undefined methodeach'` How do I force rails to always return an array of messages even if there's only one message so that each always works? Thanks!

  • Where to put reusable methods for access by controllers in rails

    - by 99miles
    I have several methods I call from my controllers that feel like they should be pulled out and put into a reusable class, outside of the controller. Where do people usually put this stuff? I know I can put them into my ApplicationController, but that doesn't seem to be a great solution if I think I can use these methods later in other applications. Also, I have a bunch of utility methods in my controllers that likely won't be used in other controllers, or in the future at all, but I feel like they just bloat my controller a bit. Do people usually move these out someplace for cleanliness or just end up with a huge controller? I'm coming from Java and Actionscript where I'd just create new util classes for this stuff.

  • Rails: periodically use HEAD to check for page changes

    - by Chris
    I have a Rails app implementing a game, so it's expected that a player will leave a browser open at the game page. When player Alan takes an action himself, I use AJAX requests to update the game page Alan is viewing to reflect the new state. However, when another player (Bob) takes an action, I don't have (or want) a mechanism to push the change to Alan's view. I would like Alan's page to periodically poll the Rails server to find if there have been any changes since last reload, and to reload the page (either via a whole-page GET or an AJAX call) if not. In order to play nicely with caches and proxies, I'd like to do this by issuing a periodic HTTP HEAD request, get Rails to work out the timestamp of the last change (trivially available from my DB) and respond with that in the Last-Modified header; then have the client-side act on that timestamp. How can I go about doing this?

  • Creating a specialised view filtering form in Rails

    - by Schroedinger
    G'day guys, I have a current set of data, and I generate multiple analyses of this data (each analysis into its own active record item called a pricing_interval) using a helper function at the moment. Currently to analyse the set of data, you need a start time(using datetime_select) an integer (using text_field) and a name (using text_field) I would like on submission of the form to be redirected to the index page of my pricing_interval, as the values will be re-generated. Manually generating a range proves that my helper methods work. How would I build a form that on submit would send parameters to a function in the form of (date,integer,name) so that it could immediately begin work whilst redirecting the user to server/pricing_intervals Anything at all would help, I've spent hours over the past few days trying to get the rails form syntax working properly to no avail, a really straightforward guide to what I would implement to get this working would be amazingly appreciated. I've looked through the form guides, as I'm not creating an object, but merely parsing params, there's got to be an easy way to do this, right?

  • Rails 3: What is the proper way to respond to REST-ful actions with JSON in rails?

    - by Damien Wilson
    Hello SO. I'm trying to make an API for my rails application using JSON responses to RESTful resource controllers. This is a new experience for me, so I'm looking for some guidance and pointers. To start things off: In a rails application, what is the "proper" way to respond with JSON to REST-ful controller methods? (create, update, destroy) Is there an idiomatic way to indicate success/failure through a JSON response? Additional information: I'm currently working with rails 3.0.beta2 I would like to avoid using a plugin or gem to do the grunt work, my goal is to gain a better understanding of how to make a rails 3 API. Links to places I could find more information on the topic would also be appreciated, some quick searching on google didn't do me much good.
