I agree with your idea to use an Achievement model. You should probably not implement the triggers in your controllers, though. Imagine that you have two ways to post a comment; you will inevitably get code duplication. This sort of behaviour belongs in a model. Suppose you want to track the number of comments that … Read more
Update your model to this class Car < ActiveRecord::Base # depending on how you deal with mass-assignment # protection in newer Rails versions, # you might want to uncomment this line # # attr_accessible :skip_method_2 attr_accessor :skip_method_2 validate :method_1, :method_3 validate :method_2, unless: :skip_method_2 private # encapsulation is cool, so we are cool # custom … Read more
If you want to cache an action, based on all the query parameters (or say on nearly all of them), you can do: caches_action :my_action, :cache_path => Proc.new { |c| c.params } Or, maybe you want all but some params that you just use for Analytics (but that have no bearing on the records you’re … Read more
With regards to the conditions with counter_cache, I would read this blog post. The one thing you should do is add the following to the migration file: add_column :employees, :projects_count, :integer, :default => 0, :null => false Employee.reset_column_information Employee.all.each do |e| Employee.update_counters e.id, :projects_count => e.projects.length end So you current projects count can get migrated … Read more
TLDR: Use environment variables! I think @Bryce’s comment offers an answer, which I’ll just flush out. It seems one approach Heroku recommends is to use environment variables to store sensitive information (API key strings, database passwords). So survey your code and see in which you have sensitive data. Then create environment variables (in your .bashrc … Read more
Rails supports Single Table Inheritance. From the AR docs: Active Record allows inheritance by storing the name of the class in a column that by default is named “type” (can be changed by overwriting Base.inheritance_column). This means that an inheritance looking like this: class Company < ActiveRecord::Base; end class Firm < Company; end class Client … Read more
Credits to http://moeffju.net/blog/using-bigint-columns-in-rails-migrations class CreateDemo < ActiveRecord::Migration def self.up create_table :demo, :id => false do |t| t.integer :id, :limit => 8 end end end See the option :id => false which disables the automatic creation of the id field The t.integer :id, :limit => 8 line will produce a 64 bit integer field
If you want all your links to be able to switch between http and https, you have to stop using the _path helper and switch to _url helpers. After that, using a scope with the protocol parameter forced and protocol constraint makes the urls automatically switch. routes.rb scope :protocol => ‘https://’, :constraints => { :protocol … Read more
You can use blocks as an alternative to the string interpolation with correct usage html_safe. For example: <%= link_to ‘#’ do %> Lorem Ipsum <%= image_tag(‘/images/menu-arrow-down.gif’) %> <% end %>
As far as I can see there is no standard method for getting the remote address of your local machine. If you need the remote address for (testing) your geocoding, I suggest adding 127.0.0.1 to your database table that matches IP addresses with locations. As a last resort you could also hard code your remote … Read more
