    <p><code>Track.points=</code> is a magic method that expects any number of <code>Point</code> objects. It adds and removes objects from the collection. You get this behaviour when you define a <code>has_many</code> association. This is why you're seeing <code>ActiveRecord::AssociationTypeMismatch</code>.</p> <p>What you actually want to do is accept nested attributes for the associated collection.</p> <pre><code>class Track &lt; ActiveRecord::Base has_many :points accepts_nested_attributes_for :points end </code></pre> <p>Sending <code>accepts_nested_attributes_for</code> will provide you with the <code>Track.points_attributes</code> magic method. It expects an array of hashes, where each hash is the attributes for building the nested object.</p> <pre><code>curl -i -X POST -H 'Content-Type: application/xml' -d '&lt;track&gt;&lt;distance&gt;100&lt;/distance&gt;&lt;points_attributes&gt;&lt;lat&gt;3&lt;/lat&gt;&lt;lng&gt;2&lt;/lng&gt;&lt;/points_attributes&gt;&lt;/track&gt;' http://localhost:3000/users/1/tracks </code></pre> <p>The Rails log may look something like this.</p> <pre><code>Processing TracksController#create Parameters: {"track"=&gt;{"distance"=&gt;"100"}{"points_attributes"=&gt;[{"lat"=&gt;"3","lng"=&gt;"2"}]}} </code></pre> <p><a href="http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html" rel="nofollow noreferrer">ActiveRecord::NestedAttributes::ClassMethods</a> API documentation.</p>

    1. COWow, this seems like it might work! Unfortunately, I am now getting an error involving "with_indifferent_access" being called on the value passed. Any advice? Processing TracksController#create (for 127.0.0.1 at 2010-04-14 10:46:27) [POST] Parameters: {"track"=>{"points_attributes"=>{"lng"=>"2", "lat"=>"3"}, "distance"=>"100"}, "user_id"=>"1"} User Load (0.6ms) SELECT * FROM "users" WHERE ("users"."id" = 1) NoMethodError (undefined method `with_indifferent_access' for "2":String): app/controllers/tracks_controller.rb:47:in `create'

    2. COIf I change your XML I can insert a single point: "curl -i -X POST -H 'Content-Type: application/xml' -d '<track><distance>1000</distance><points_attributes><point><lat>39</lat><lng>29</lng></point></points_attributes></track>' http://localhost:3000/users/1/tracks" Unfortunately, this doesn't work for 2: "curl -i -X POST -H 'Content-Type: application/xml' -d '<track><distance>1000</distance><points_attributes><point><lat>39</lat><lng>29</lng></point><point><lat>39</lat><lng>29</lng></point></points_attributes></track>' http://localhost:3000/users/1/tracks" How do I format the XML for 2?

    3. COOkay, I think I've go it now. The following XML seems to work. <track> <distance>1000</distance> <points_attributes> <lat>39</lat><lng>29</lng> </points_attributes> <points_attributes> <lat>2</lat><lng>5</lng> </points_attributes> </track> YEAH! Thank you soo much for pointing me in the right direction.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
