    <p>I am trying to assign a team to a player. A player can have many teams but upon initial set up they only have one. I am trying to set up a choice so the user can pick a team.</p> <p>When I submit the form the data for the other fields, first_name and last_name submit fine however no data gets saved in the join table. I am using a select box however check boxes will do the job too if someone can think of that.</p> <h2>Models</h2> <p>I have 2 models. Players and Teams set up with a HABTM relationship.</p> <pre><code>class Player &lt; ActiveRecord::Base has_and_belongs_to_many :teams class Team&lt; ActiveRecord::Base has_and_belongs_to_many :players </code></pre> <h2>Controller</h2> <pre><code> def new @player = Player.new end def create @player = Player.new(params[:player]) if @player.save flash[:notice] = "Player Created" redirect_to(:action =&gt;'list') else render('new') end end </code></pre> <h2>Join table</h2> <p>I can insert data into the the join table from the rails console. I can then get this data and show it. So the relationships work.</p> <pre><code>create_table "players_teams", :id =&gt; false, :force =&gt; true do |t| t.integer "player_id" t.integer "team_id" end add_index "players_teams", ["player_id", "team_id"], :name =&gt; "index_players_teams_on_player_id_and_team_id" </code></pre> <h2>View</h2> <p>In my view I have this </p> <pre><code>&lt;%= f.collection_select(:team_id, Team.all, :id, :name, :prompt =&gt; true) %&gt; </code></pre> <p>This loads a view with the teams Populated. Once submitted I get</p> <pre><code>Parameters: {"utf8"=&gt;"✓", "authenticity_token"=&gt;"kvOmx3G5H1mqLMnEn6HS3a79+WQnIzfsUA3Dt0XHo1w=", "player"=&gt;{"first_name"=&gt;"Test", "last_name"=&gt;"Data", "email"=&gt;"email@email.com"}, "teams"=&gt;{"team_id"=&gt;"1"}, "commit"=&gt;"create player"} </code></pre> <p>I am not sure where to go from here. </p>

    1. COYour problem is that you don't do anything with params[:teams] in the create action. The team ids are not in the params[:player] hash ;)

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
