Join Table confusion

I have a view in which I would like to set values for three separate join tables. Everything seems to work fine from the console but when I use the _form.rhtml it only inserts values into the first join table.

This is what I have in my _form.rhtml

<p>   <label for="technicians">Technicians:</label><br />   <select id="technicians" name="technicians" multiple="multiple" size="5" style="width:250px;">     <%= options_from_collection_for_select(@all_technicians, :id, :name, @selected_technicians) %>   </select> </p>

<p>   <label for="computers">Computer Models:</label><br />   <select id="computers" name="computers" multiple="multiple" size="3" style="width:150px;">     <%= options_from_collection_for_select(@all_computers, :id, :model, @selected_computers) %>   </select> </p>

<p>   <label for="licensed_programs">Licensed Software:</label><br />   <select id="licensed_programs" name="licensed_programs" multiple="multiple" size="8" style="width:200px">     <%= options_from_collection_for_select(@all_licensed_programs, :id, :name, @selected_licensed_programs) %>   </select> </p>

The html that is generated looks good too

<p>   <label for="technicians">Technicians:</label><br />   <select id="technicians" name="technicians" multiple="multiple" size="5" style="width:250px;">     <option value="4">Albert Martinez</option> <option value="6">Chris Sanchez</option> <option value="3">Luis Arvizu</option> <option value="5">Orlando Garcia</option> <option value="2">Richard Martinez</option>

<option value="1">Thao Dang</option>   </select> </p>

<p>   <label for="computers">Computer Models:</label><br />   <select id="computers" name="computers" multiple="multiple" size="3" style="width:150px;">     <option value="1">Dell GX240</option>   </select>

</p>

<p>   <label for="licensed_programs">Licensed Software:</label><br />   <select id="licensed_programs" name="licensed_programs" multiple="multiple" size="8" style="width:200px">     <option value="1">VIZ</option>   </select> </p>

I would guess I'm missing how/where it's being passed to ActiveRecord. Although technicians works and I have the subsequent two constructed in a similar fashion.

Any help would be greatly appreciated.

Thanks, Glen

Thank, I appreciate the reply. I was being stupid though and had a couple of pieces missing in the controller.

Will <%= select :model, :technicians, @all_technicians %> generate a multi-select? i.e. does it generate based on the relations defined in the model?
