Select helper

Rails
1

How do I amend the form helper:

<%= select(“lead”, “associate_id”, Associate.all.collect {|p|
[ p.to_s, p.id ] }, {:include_blank => ‘’}) %>

(which is magnificently SIMPLE, and I don’t want to convolute it here,
which is why I am asking the experts on this list…)

To NOT display records where Associate.deleted != 0 ?

Additionally, how would I amend it if I have and Associate.id that I
want to be selected in it? Thanks guys.

You could provide a named scope of Associate that finds records where
deleted != 0 (called active or whatever is right for you) then use
Associate.active instead of Associate.all.
In fact I would also provide a method of Associate that returns the
collected data, then it becomes even simpler
<%= select(“lead”, “associate_id”, Associate.options_for_select,
{:include_blank => ‘’}) %>
This also makes testing simpler as you can test options_for_select in
a unit test.

Additionally, how would I amend it if I have and Associate.id that I
want to be selected in it? Thanks guys.

Sorry I don’t understand the question

Suppose I have the following then in my view – I am creating a form
for the model ‘Lead’ and there is a field lead.associate_id. In my
controller, I am setting a variable to a model @Up, and @Up has an
associate_id also. I would like the default lead.associate_id be set
in my select with the @Up.associate_id. Please note the second line in
my view code below (which does not work, of course). How can I default
the lead.associate_id on this form to create a new lead to be equal to
the @Up.associate_id ?

<% form_for :leads, :url => { :controller => ‘channels’, :action =>
“lead” }, :html => {:name => ‘leadform’} do |f| %>
<% lead.associate_id = @Up.associate_id %>
<%= select(“lead”, “associate_id”, Associate.find(:all, :order =>
‘associates.lastname ASC’, :conditions => [‘deleted=0’]).collect {|p|
[ p.to_s, p.id ]}, {:include_blank => ‘’}) %>

<% form_for :leads, Â :url => { :controller => ‘channels’, :action =>
I would expect this to be :lead (singular)

“lead” }, :html => {:name => ‘leadform’} do |f| %>
 <% lead.associate_id = @Up.associate_id %>

Should this be @lead.associate_id = @Up.associate_id?

<%= select(“lead”, “associate_id”, Associate.find(:all, Â :order =>
‘associates.lastname ASC’, Â :conditions => [‘deleted=0’]).collect {|p|
[ p.to_s, p.id ]}, {:include_blank => ‘’}) %>

If you are using form_for why are you not using f.select?

However, if I add in :

<% @lead.associate_id = @Up.associate_id %>

Nothing happens ? Additionally, I try making this statement in te
method of the controller which renders the partial that this view code
is in, again, nothing happens (i.e. it does not select the associate
in the select box)

I use :associate_id in f.select but I don’t think that should make any
difference.
Have you verified just before the f.select that @lead.associate_id is
a value from the set? Display the id on the form and check the html
(View, Page Source or similar in browser) to check that the id is in
the selection set.
Try it without the include_blank option (clutching at straws here).

I see where the problem is arising (but not its solution). My form is
in a div that is hidden. My controller method is called via a
javascript function, which also invoked the form (which is in a
partial, in a div, re-rendering the partial) and the javascript, after
calling the controller method, invokes a redbox on the div/partial
with the form. This is causing a big problem here.

I must set the selected value for the select box in my javasript
method I believe, before invoking redbox. I will post this to the
appropriate javascript forum. Thanks for all of yoiur help on this
knotty problem! -RVince

Whoops! You’re right!

<% form_for :lead, :url => { :controller => ‘channels’, :action =>
“lead” }, :html => {:name => ‘leadform’} do |f| %>
<%= f.label :origin %>

<%= f.select( “associate_id”, Associate.find(:all, :order =>
‘associates.lastname ASC’, :conditions => [‘deleted=0’]).collect {|p|
[ p.to_s, p.id ]}, {:include_blank => ‘’}) %>

However, if I add in :

<% @lead.associate_id = @Up.associate_id %>

Nothing happens ? Additionally, I try making this statement in te
method of the controller which renders the partial that this view code
is in, again, nothing happens (i.e. it does not select the associate
in the select box)
