[Rails] collection_select default selected value

Hiall,

Unfortunately I just can''t find out how to setup a default selected
value when using collection_select. My call is like so:

<%= collection_select(:consultant, :lastname, @consultants, :id,
:lastname, { :selected => @current_consultant.id } )  %>

which is not working, I debugged so far that I know that
@current_consultant.id contains the correct value.

Any tips?

cheers
Martin

[Rails] collection_select default selected value

Hi Kevin,

Sorry for replying late! The generated HTML looks like:

<select id="communal_audit_consultant_lastname"
name="communal_audit_consultant[lastname]"><option
value="1">Auinger</option>
<option value="2">Katterl</option></select>

try this...

:selected => @current_consultant.id.to_s

The ''values'' that the select compares against are really
strings.  Not
sure if they get properly cast for the purposes of the comparison needed  
to set the selected one.

[Rails] collection_select default selected value

Thx for the tip but that didn''t work. In the meantime I found out that
a call to
<% options = options_from_collection_for_select(@consultants, :id,
:lastname, @current_consultant.id) %>

produces correct option tags like:

<option value="1">Auinger</option>
<option value="2"
selected="selected">Katterl</option>

However, I find no way to wrap this into a select tag. ..

There must be an easier way???

cheers
Martin

[Rails] collection_select default selected value

I''ve tried that before :) This leads to very strange:

<select id="communal_audit_consultant_lastname"
name="communal_audit_consultant[lastname]"><option
value="&lt;option
value=&quot;1&quot;&gt;Auinger&lt;/option&gt;
">&lt;option
value=&quot;1&quot;&gt;Auinger&lt;/option&gt;
</option>
<option value="&lt;option value=&quot;2&quot;
selected=&quot;selected&quot;&gt;Katterl&lt;/option&gt;">&lt;option
value=&quot;2&quot;
selected=&quot;selected&quot;&gt;Katterl&lt;/option&gt;</option></select>

showing the whole option strings in the dropdown ...

I also tried to give the parameters as a hash with keys corresponding
to parameters of options_from_collection_for_select. This also doesn''t

[Rails] collection_select default selected value

Going through the AWDWR book I decided to go another way. I now have

@consultants = CommunalAuditConsultant.find(:all, :order =>
"lastname"
).map {|c| [c.lastname, c.id] }

in my controller, and then

<%= select(:communal_audit_consultant, :id, @consultants)  %>

in my partial

This works perfectly!

Thx for your patience and tips, Kevin!

cheers

[Rails] collection_select default selected value

You could add in your controller method...

@consultants.lastname = ''bla''

This has always worked for me - just follow the docs ;)

<%= select_tag ''my[select]'', 
options_from_collection_for_select(Model.find(:all),''id'',''name'',some_string)
%>

where some_string = an actual string (i.e. ''Joe'') or a
variable (ala
@person.name).

Works like a charm - everytime.

Cheers,
divotdave

Re: collection_select default selected value

Martin is right, but would like to add a comment. If you do

<%= select_tag ''my[select]'',
options_from_collection_for_select(Model.find(:all),''id'',''name'',some_string)
%>

Then you do need to pass some_string as string. However, if you are 
passing  symbols, the you would need to convert to the symbol''s type:

<%= select_tag ''my[select]'',
options_from_collection_for_select(Model.find(:all),:id,:name,some_string.to_i)
%>

Hope that helps someone

Re: collection_select default selected value

Hi,

I have some issues with setting the selected value. On my page, user 
selects a State from the drop down and other attributes and click on 
"Find". I want to set the default value of the drop down to the value 
selected prior to clicking "Find".

<%=collection_select(:state, :state_id, @states, :state_id, :state_name,
          {:prompt => true,  :selected => @selected_state},
          {:style => ''width:200px;'',
               :onchange => remote_function(:url =>
                 {:action => ''update_cities''},:with => 
"''state_id=''+value")})%>

In my controller, if I have @selected_state = 1, the dropdown default 
value is shown in the UI. However,  if I have @selected_state = 
state_id, the default value is not set.

Snippet of the code in my controller:

def find
    state_id = params[:state][:state_id]

    @selected_state = state_id

    /* Some logic here */

    @states = State.find(:all)

   respond_to do |format|
        format.html { render :action => "index" }
   end
 end

Any pointers are appreciated. Thanks.

Re: collection_select default selected value

Thanks for the link Zt Di.

@selected_state = state_id.to_i works.

This is because state_id = params[:state][:state_id] returns a string.

Re: collection_select default selected value

Agree with you . Someone should merge the documentation there to the
Rails API. The rails api''s collection_select doc is somewhat
incomplete or too brief. In short, it''s not helpful.
