select in list.rhtml

i am new to ruby on rails, and this might be a simple one but i have
no idea what to do.
i need to put a select (_tag or whatever) into a list.rhtml and get
the selected value from this. Putting the select to the view works
fine. The displayed options are ok too, but i don''t know how to get
the selected option. What i have so far:

<% for calendar in @calendars %>
<tr>
<td><%= link_to "#{calendar.person.account}", { :controller
=>
''person'', :action => ''list'', :person_id
=> calendar.person.id } %></
td>
<td><%= link_to "#{calendar.calendar_state.name}", {
:controller =>
''calendar'', :action => ''list'',
:calendar_state_id =>
calendar.calendar_state } %></td>
<td><%= select ''calendar'',
''project_has_person_id'',
ProjectHasPerson.find(:all, :conditions => ["person_id = ?",
calendar.person.id]).collect{ |p| [p.person.account + "@" +
p.project.name, p.id]} %></td>

  <% for column in Calendar.content_columns %>
    <td><%=h calendar.send(column.name) %></td>
  <% end %>
	<td><%= link_to ''assign'', :action =>
''assign'', :id => calendar %></
td>
  </tr>
<% end %>

The calendar-entry has a column called project_has_person_id, but
whenever i try to access the parameter in the controller with
params[:project_has_person_id] the value will be nil.

Any help is appreciated!

Thanks

I suspect that the value is in params[:calendar][:project_has_person_id].

The development log will show you all of the values of the params object.

Re: select in list.rhtml

i have tried your solution, but it didn''t work either.

selection to a controller?

Re: select in list.rhtml

Hi macro,

 Try to place your select statement inside a form tag instead of
link_to, only then it submits the selection to the controller.
 Then you need to access the selection by params[:calendar]
[:project_has_person_id] as stated by Christopher.

Thanks,
Kiran.
