• With Apache, is it possible to generate a directory listing for a non-folder URL?

  - by William Denniss

  Apache allows you to create a directory list (when configured) if you visit a folder with no index.html. What I want to know is, is it possible to get that same list but at a different URL? I'm already using index.html and want to keep it that way. i.e., this is what I'm looking for: http://example.com/blar/ - loads my index.html page (don't want this to change) http://example.com/blar/directory_list (I want this url to render the apache directory list instead)

• Saving a record in Authlogic table

  - by denniss

  I am using authlogic to do my authentication. The current model that serves as the authentication model is the user model. I want to add a "belongs to" relationship to user which means that I need a foreign key in the user table. Say the foreign key is called car_id in the user's model. However, for some reason, when I do u = User.find(1) u.car_id = 1 u.save! I get ActiveRecord::RecordInvalid: Validation failed: Password can't be blank My guess is that this has something to do with authlogic. I do not have validation on password on the user's model. This is the migration for the user's table. def self.up create_table :users do |t| t.string :email t.string :first_name t.string :last_name t.string :crypted_password t.string :password_salt t.string :persistence_token t.string :single_access_token t.string :perishable_token t.integer :login_count, :null => false, :default => 0 # optional, see Authlogic::Session::MagicColumns t.integer :failed_login_count, :null => false, :default => 0 # optional, see Authlogic::Session::MagicColumns t.datetime :last_request_at # optional, see Authlogic::Session::MagicColumns t.datetime :current_login_at # optional, see Authlogic::Session::MagicColumns t.datetime :last_login_at # optional, see Authlogic::Session::MagicColumns t.string :current_login_ip # optional, see Authlogic::Session::MagicColumns t.string :last_login_ip # optional, see Authlogic::Session::MagicColumns t.timestamps end end And later I added the car_id column to it. def self.up add_column :users, :user_id, :integer end Is there anyway for me to turn off this validation?

• Ignoring extra keys in a hash passed in to create

  - by denniss

  Does rails provide a way to ignore extra keys that are passed in to create. Supposed User has two attributes, first_name and last_name. When I do User.create({ :first_name => "first", :last_name => "last", :age => 10}) that line gives me an UknonwnAttributeError. Well, that makes sense, it happens cause age is not one of the attributes. But is there a way to just ignore key-value pair that is not one of the attributes for User?

• How does UITableViewController knows its dataSource and delegate

  - by denniss

  I am following the BigNerdRanch iOS Programming book and I am on this one chapter that deals with UITableViewController. I have been wondering however where UITableViewController finds out about its delegate and dataSource. Currently I have it as @interface ItemsViewController : UITableViewController <UITableViewDataSource, UITableViewDelegate> But there is nothing that looks like: [self.tableView setDelegate:self] I am just wondering how the UITableViewController finds out about its delegate and dataSource

• XMLAdapter for HashMap

  - by denniss

  I want to convert a list of items inside of my payaload and convert them into a hashmap. Basically, what I have is an Item xml representation which have a list of ItemID. Each ItemID has an idType in it. However, inside my Item class, i want these ItemIDs to be represented as a Map. HashMap<ItemIDType, ItemID> The incoming payload will represent this as a list <Item>... <ItemIDs> <ItemID type="external" id="XYZ"/> <ItemID type="internal" id="20011"/> </ItemIDs> </Item> but I want an adapter that will convert this into a HashMap "external" => "xyz" "internal" => "20011" I am right now using a LinkedList public class MapHashMapListAdapter extends XmlAdapter<LinkedList<ItemID>, Map<ItemIDType, ItemID>> { public LinkedList<ItemID> marshal(final Map<ItemIDType, ItemID> v) throws Exception { ... } public Map<ItemIDType, ItemID> unmarshal(final LinkedList<ItemID> v) throws Exception { ... } } but for some reason when my payload gets converted, it fails to convert the list into a hashmap. The incoming LinkedList of the method unmarshal is an empty list. Do you guys have any idea what I am doing wrong here? Do I need to create my own data type here to handle the LinkedList?

• Preloading data without messing up association when data is loaded the 2nd time.

  - by denniss

  This is how my model looks like User belongs_to :computer Computer has_many :user Users are created when people register for an account on the web site but computers are pre-loaded data that I create in seeds.rb/some .rake file. All is fine and good when the app is first launched and people start registering and get associated with the right computer_id. However, suppose I want to add another computer to the list Computer.destroy_all Computer.create({:name => "Akane"}) Computer.create({:name => "Yoda"}) Computer.create({:name => "Mojito"}) #newly added running the rakefile the second time around will mess up the associations because computer_id in the User table refer to the old id in Computer table. Since I have run the script above, the id keeps incrementing without any regard to the association that user has to it. Question: Is there a better way for me to pre-load data without screwing up my association? I want to be able to add new Computer without having to destroy the user's table. Destroying the computer table is fine with me and rebuilding it again but the old association that the existing users have must stay intact.
