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 %\>
\<%= link\_to "#{calendar.person.account}", { :controller =\> 'person', :action =\> 'list', :person\_id =\> calendar.person.id } %\> \<%= link\_to "#{calendar.calendar\_state.name}", { :controller =\> 'calendar', :action =\> 'list', :calendar\_state\_id =\> calendar.calendar\_state } %\> \<%= 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]} %\>
\<% for column in Calendar.content\_columns %\>
\<%=h calendar.send(column.name) %\>
\<% end %\> \<%= link\_to 'assign', :action =\> 'assign', :id =\> calendar %\> \<% 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.

thank you for your reply.
i have tried your solution, but it didn’t work either.
is there really no way to pass a selected value coming from a
selection to a controller?

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.
