  • is Web Development moving too fast?

    - by Imran
    I find myself constantly learning new things in web development and there is always soo much to learn in general. Currently i work with PHP and have tried to keep up with Ruby on Rails(RoR) but it's moving so fast i'm not sure i can keep up with the latest changes. Does anyone else have trouble keeping up with so much innovation in web development or is it just me? And how do you guys cope with the never ending learning process especially with Rails? Just looking for tips Tricks and personal experiences really Thanks in advance;-)

  • Filtering custom fields on wordpress admin page

    - by Kyril
    I'm currently working on a wordpress 2.9.2 plugin (my first) that creates additional custom fields that will later be read from the template. The plugin adds an additional meta box to the "Edit Post" screen which is responsible for manipulating these values. My problem is that the custom fields generated by the plugin also show up in the "Custom Fields" box. Ideally I would like for the custom fields generated by the plugin to be managed separately from any other custom fields for that same post/page. Is there a way that I can filter fields specific to my plugin to prevent them from being displayed in the "Custom Fields" box? I have yet to locate any action or filter that will let me capture and manipulate those values before they are rendered on "Edit Post".

  • How can I avoid running ActiveRecord callbacks?

    - by Ethan
    I have some models that have after_save callbacks. Usually that's fine, but in some situations, like when creating development data, I want to save the models without having the callbacks run. Is there a simple way to do that? Something akin to... Person#save( :run_callbacks => false ) or Person#save_without_callbacks I looked in the Rails docs and didn't find anything. However in my experience the Rails docs don't always tell the whole story. UPDATE I found a blog post that explains how you can remove callbacks from a model like this: Foo.after_save.clear I couldn't find where that method is documented but it seems to work.

  • Enforcing a Uniqueness Constraint in a Nested Form

    - by Euwyn
    I'm trying not to fight the defaults here and use Rails built-in support for nested attributes (from http://ryandaigle.com/articles/2009/2/1/what-s-new-in-edge-rails-nested-attributes). I'm labeling Things with Tags, and all works swell, and for each Thing I have a form with a nested field that creates a new Tag by a name. Trouble is, I need to make sure that each Tag has a unique name. Instead of creating a new Tag, if a user enters the name of one that already exists, I need to create the associate with that pre-existing Tag. How do I do this?

  • Rendering another Action without changing URL?

    - by Michael Stum
    I have this code in my Rails 3 controller: def index now = Time.now.utc.strftime("%m%d") redirect_to :action => "show", :id => now end def show begin @date = Time.parse("12#{params[:id]}") dbdate = params[:id] rescue ArgumentError @date = Time.now.utc dbdate = @date.strftime("%m%d") end @date = @date.strftime("%B %d") @events = Event.events_for_date(dbdate) end So basically index is just a specialized version of show, hence I want it to execute show, render the show.html.erb view - but I do not want to change the URL like redirect_to does. I have tried this approach: def index now = Time.now.utc.strftime("%m%d") params[:id] = now show render :action => "show" end Now, this works, but it just smells badly. I'm new to Ruby and Rails, so I just wonder if there is something fundamentally wrong or if there is a better way to do this?

  • Why are all response bodies after the first blank in Cucumber?

    - by James A. Rosen
    I'm using Cucumber (0.6.3), Cucumber-Rails (0.3.0), Webrat (0.7.0), and Rails (2.3.5) for some tests. The following scenario passes just fine: Scenario: load one page Given I am on the home page Then I should see "Welcome" The following, however, fails: Scenario: load two pages Given I am on the FAQ pag When I go to the home page Then I should see "Welcome" The problem is that the second @response.body is blank. I added a Rack middleware to get a little more information: class LogEachRequest def initialize(app); @app = app; @count = 0; end def call(env) puts "Processing request # #{@count += 1)" @app.call(env) end end It shows me only one request processed. That is, it only ever prints out Processing request # 1

  • Can you explain what's going on in this Ruby code?

    - by samoz
    I'm trying to learn Ruby as well as Ruby on Rails right now. I'm following along with Learning Rails, 1st edition, but I'm having a hard time understanding some of the code. I generally do work in C, C++, or Java, so Ruby is a pretty big change for me. I'm currently stumped with the following block of code for a database migrator: def self.up create_table :entries do |t| t.string :name t.timestamps end end Where is the t variable coming from? What does it actually represent? Is it sort of like the 'i' in a for(i=0;i<5;i++) statement? Also, where is the :entries being defined at? (entries is the name of my controller, but how does this function know about that?)

  • Set database based on how the application was started

    - by AaronThomson
    I have two Rails applications (lets call them APP-1 and APP-2), each of them has a dependancy on a third Rails application (APP-3). I would like to be able to run the tests for APP-1 and APP-2 in parallel on my CI server. The problem is, both need to start up APP-3 and write to a DB via the APP-3. This causes conflicts and failures if the tests are run in parallel. My idea for a solution is for APP-1 and APP-2 to each start their own instance of APP-3 and to have each instance point to a different DB. Is there a way to dynamically set the DB in the database.yml of APP-3 so that it connects to a different DB depending on which APP starts it up? FYI. APP-1 and APP-2 currently start APP-3 via rake tasks.

  • Incorrect error

    - by jspooner
    If you assign an invalid date (like December 39th) to a datetime column ActiveRecord returns a "can't be blank" error when is should probably return an error like "Not a valid date" My question. Is this expected rails behavior, a bug or, something that I could patch? class ExerciseLog < ActiveRecord::Base validates_presence_of :scheduled_datetime end Fire up the console. e = Log.new # lets set a date for Dec 39th which obviously doesn't exist e.scheduled_datetime = "2010-12-39" e.save => false # this is the confusing message since our form did post a valid date e.errors.on(:scheduled_datetime) => "can't be blank" e.scheduled_datetime = "2010-12-30" e.save => true I discovered this issue when I accidentally transposed the month and day values. btw This is in Rails 2.3.5

  • Can't destroy record in many-to-many relationship

    - by Dmart
    I'm new to Rails, so I'm sure I've made a simple mistake. I've set up a many-to-many relationship between two models: User and Group. They're connected through the junction model GroupMember. Here are my models (removed irrelevant stuff): class User < ActiveRecord::Base has_many :group_members has_many :groups, :through => :group_members end class GroupMember < ActiveRecord::Base belongs_to :group belongs_to :user end class Group < ActiveRecord::Base has_many :group_members has_many :users, :through => :group_members end The table for GroupMembers contains additional information about the relationship, so I didn't use has_and_belongs_to_many (as per the Rails "Active Record Associations" guide). The problem I'm having is that I can't destroy a GroupMember. Here's the output from rails console: irb(main):006:0> m = GroupMember.new => #<GroupMember group_id: nil, user_id: nil, active: nil, created_at: nil, updated_at: nil> irb(main):007:0> m.group_id =1 => 1 irb(main):008:0> m.user_id = 16 => 16 irb(main):009:0> m.save => true irb(main):010:0> m.destroy NoMethodError: undefined method `eq' for nil:NilClass from /usr/local/lib/ruby/gems/1.8/gems/activesupport-3.0.4/lib/active_support/whiny_nil.rb:48:in `method_missing' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/persistence.rb:79:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/locking/optimistic.rb:110:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/callbacks.rb:260:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activesupport-3.0.4/lib/active_support/callbacks.rb:413:in `_run_destroy_callbacks' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/callbacks.rb:260:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:235:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:292:in `with_transaction_returning_status' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/connection_adapters/abstract/database_statements.rb:139:in `transaction' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:207:in `transaction' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:290:in `with_transaction_returning_status' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:235:in `destroy' from (irb):10 This is driving me crazy, so any help would be greatly appreciated.

  • How do you move an admin menu item in Magento

    - by Josh Pennington
    I currently have an extension that I created and it currently sits inside of its own top level menu. I would like to move it so that the item would appear inside of the Customers menu. Does anyone know how to do this? It looks like this is handled inside the extensions config.xml file. The code that I have for it right now is as follows: <menu> <testimonials module="testimonials"> <title>Testimonials</title> <sort_order>71</sort_order> <children> <items module="testimonials"> <title>Manage Items</title> <sort_order>0</sort_order> <action>testimonials/adminhtml_testimonials</action> </items> </children> </testimonials> </menu> I tried changing the title element to Customers and it just created a duplicate Customers menu. Does anyone have any ideas? Thanks Josh Pennington

  • Which PHP framework for a RoR developer?

    - by Horace Ho
    For one specific client I have to use PHP. This and this question were 2 years old. I'd like to know is there any update of opinion for year 2010? My background on web development is mainly rails. I can code in PHP (for example, write a module for Drupal) but never used any PHP framework for any project. I can see the following potential features to be needed in my project: authlogic-like user access control will_paginate-like paging for long listings paperclip-like simple file upload prawn-like PDF generation restful url and my personal favorite ruby/rails features: activerecord <% @list.each do |item| %> synstax instead of for ($i=1; $i<=$row_num; $i++) ... rake:db migrate script/console Thanks!

  • Tracking DB changes with Zend Framework?

    - by Chad Johnson
    I am trying to decide between the Zend Framework and Ruby On Rails for my web application. If I go with ZF, I need the following: A way to incrementally track changes to my database, as with RoR's migration feature (001_something.sql, 002_something_else.sql). A place to put SQL for the next release of my software. At work in our custom PHP solution, we just have release.sql, which gets run, archived, and blanked out upon release. ZF has Zend_Db_Schema_Manager, which does the same thing, but I'm not interested as its not official, complete, or maintained. Is there an official mechanism that ZF provides for doing something similar to what I described? EDIT I ended up going with Rails. Nothing compares.

  • Trouble rendering a view inside a generic class

    - by Horace Loeb
    I'm trying to encapsulate the logic for generating my sitemap in a separate class so I can use Delayed::Job to generate it out of band: class ViewCacher include ActionController::UrlWriter def initialize @av = ActionView::Base.new(Rails::Configuration.new.view_path) @av.class_eval do include ApplicationHelper end end def cache_sitemap songs = Song.all sitemap = @av.render 'sitemap/sitemap', :songs => songs Rails.cache.write('sitemap', sitemap) end end But whenever I try ViewCacher.new.cache_sitemap I get this error: ActionView::TemplateError: ActionView::TemplateError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.url_for) on line #5 of app/views/sitemap/_sitemap.builder: I assume this means that ActionController::UrlWriter is not included in the right place, but I really don't know

  • Solr Vs. Sphinx in a Ruby project

    - by Robert Ross
    I have a project that is being written on top of the Grape API framework in ruby. (https://github.com/intridea/grape) The problem I'm having is that Thinking-Sphinx vs. Sunspot (Gems used to interface with each search index) have worlds different benchmarks. View the Benchmark Here We're trying to develop something that is quick and easy to deploy (Solr needs Java). The issues we see right now is mainly that Solr is slower through Sunspot gem and Sphinx is faster through Thinking-Sphinx because Solr is HTTP REST calls where Sphinx is sockets. Anyone have any experience in either and can explain pitfalls / bonuses? Note: Needs to be deployable to Rails AND non-rails apps (Hence Sunspot). Thanks!

  • Starting mongrel with a custom command line argument

    - by whaka
    I would like to be able to start a mongrel or webrick server by passing an extra command line argument that I can read somewhere inside my rails application. An example would be: ruby script/server -p3000 --target=FOO Here, --target is a custom switch who's value I would like to intercept in my rails application. However, this yields the error: server: invalid option: --target=FOO I found mongrel documentation which mentions a -C (--config=PATH) argument specifying a full path to a yml configuration file, but specifying that switch gives the same error as above. I presume this option is deprecated. Is there another way to accomplish this?

  • How do I render a partial to a string from within a filter attached to a controller

    - by Tristan Havelick
    I have some code I need to use in multiple controllers in a rails 1.0 application (I can't, for strange reasons upgrade to a newer rails). I've extracted the relevant code into a filer object, and I'm using the around_filter construct to execute it. Before the extract, I was using the method render_to_string() to get the contents of a rendered partial into a string. However, this method is protected, so I am unable to access it from within my Filter object. As a workaround, I tried adding this to my ApplicationController: def render_to_string(*a) super(*a) end this seems to have remedied the protection level issue, but now I get the error: Can only render or redirect once per action When no such error occurred before the extraction. Why? Is there a different approach I should take here?

  • [Symfony] Admin generator and i18n

    - by David
    I have read lots of questions about i18n, but I haven't found any about performance. I have a simple backend app listing the contents of an ads table. These ads have a category, that is translated in some languages (it's defined as i18n in the Doctrine schema). So, when I add a "table_method" in my generator.yml to include de Category table, it reduces the number of queries, but there are yet some of them referencing i18n translation tables. So, if I add the category Translation table to the query, it reduces even more the queries BUT it increases the processing time considerably. Why this time penalty? Just because of the translation table? And why isn't the filter using this method to avoid so many translation queries as well? I mean, if I want to filter by category, it is making one query per category to include the translation table. Why??
