 h3. The Types of Associations
 
-In Rails, an _association_ is a connection between two Active Record models. Associations are implemented using macro-style calls, so that you can declaratively add features to your models. For example, by declaring that one model +belongs_to+ another, you instruct Rails to maintain Primary Key-Foreign Key information between instances of the two models, and you also get a number of utility methods added to your model. Rails supports six types of association:

 As you've seen in the previous sections, values from forms can be at the top level of the +params+ hash or nested in another hash. For example in a standard +create+
 action for a Person model, +params[:model]+ would usually be a hash of all the attributes for the person to create. The +params+ hash can also contain arrays, arrays of hashes and so on.
 
-Fundamentally HTML forms don't know about any sort of structured data, all they generate is name-value pairs, where pairs are just plain strings. The arrays and hashes you see in your application are the result of some parameter naming conventions that Rails uses.

 TIP: You may find you can try out examples in this section faster by using the console to directly invoke Rails' parameter parser. For example <pre> ActionController::UrlEncodedPairParser.parse_query_parameters "name=fred&phone=0123456789" # => {"name"=>"fred", "phone"=>"0123456789"} </pre>
