Currently I have a list of clients with a link next to each one so I can
add a new task for that particular client.
When I click the link to go to the new task view page I''d like to
retain
the clients_id so that it can be pre-selected in the pulldown menu which
allows me to assign a client otherwise.
I can see the client_id being passed in the url and I can render it on
the new task form page by using <%= @client_id %> but using a select
menu or collection_select the client_id is not preselected.
Specifically,
In my client list view I have this:
<%= link_to ''add task'', { :action =>
''new'', :controller => "tasks",
:client_id => client.id } %>
In my task controller in the new function definition I have:
@client_id = params[:client_id]
And in the task form I''m using this to create a pulldown menu of client
company names:
<%= select(''task'', ''client_id'',
all_clients.collect {|p| [
p.company_name, p.id ] } ) %>
At first I was trying to use collection_select since it seemed easier
but that didn''t work either.
I hope this doesn''t seem too vague or basic or something to answer. Any
help or pointers appreciated.

Re: newbie: Can I preselect pulldown option from passed in v
If you use select(''task'', ''client_id'', ...)
Then the drop down will preselect the value given by calling the
client_id method on @task, so set @task.client_id to the value passed
through the params and you should be ok.

Thanks! Adding <% @task.client_id = @client_id %> above the form did the trick.
