Question: Help with select tag

I want to create a select tag from a table. Looking through the API
don''t believe I could find it.
Table has an id and label.  Labels would be displayed, id would be saved.

TIA
Stuart

Re: Question: Help with select tag

Thanks I wound up going with this :

<%@states = State.find(:all, :order => "name")
collection_select(:state, :name, @states, :id, :name)
%>

Just wondering , this is in the view , I probably should move this to
the model, i.e.
def list_states
.......
end

Or helper or controller, I realize I have all options but since I''m a
rails newb open for suggestions.

Re: Question: Help with select tag

Now I''m having a problem.  In my controller I have this:
def state
@states = State.find(:all, :order => "name")
end

When I try to access the @states in the view I get a nil error:
<%collection_select(:state, :name, @states, :id, :name)
%>

What am I missing ?

TIA

Re: Question: Help with select tag

I think you need to do that in the action before you use it.  I mean, it 
can''t be in ''state'' cos that is called when you go
to:
http://localhost:3000/controller/state

If you want it to be accessed in other places, you will need to put it 
in those functions, places like ''new'',
''create'', ''update'' etc..

Hope this helps,
Cheers
Mohit.

Most likely @states doesn''t exist when the view is rendered. In the
standard
scaffold, you must setup @states in the edit, new and [for the validation
errors] in the error part of the update actions.

Re: Question: Help with select tag

The API doc is a bit confusing on collection_select:
collection_select(object, method, collection, value_method,
text_method, options = {}, html_options = {})
So object I''d think would be State and method I could call list_state
(in the controller)
or maybe I''m better off putting in the model though that
hasn''t worked
either yet.

Re: Question: Help with select tag

I had yesterday a similar problem; because I thought I might need exactly
this list in other tables, too I did this to application_helper.rb:

module ApplicationHelper
  def country_select(parent, fk = :country_id, opt = {:include_blank =>
true})
    countries = Country.find :all, :order => :name
    collection_select(parent, fk, countries, :id, :name, opt)
  end
end

<p><label
for="breeder_country_id">Country</label><br/>
<%= country_select :breeder %></p>


But note that I''m also new to ruby & rails - I''m sure
there are much better
approaches. e.g. this misses some handling of the default opt parameter.

Re: Question: Help with select tag

Incorrect.

Lets say you have a model "address", that contains a column
"state_id":

@states = State.find(:all)

Then in your view:

collection_select ("address", "state_id", :id, :name)

When the form is posted, the id of the selected "state" will be
@address.state_id (assuming @address = Address.new(params[:address])) 

Maybe this is more along the lines of what you are looking to do?

Re: Question: Help with select tag

Thanks but no , still getting a nil object.
What I don''t get up the CRUD reference (above) is that all I"m
trying
to do is create the list / array and access it from the form. It''s not
going to be updated , merely a form element to get values from .

Maybe, but I think this is similar to what I''m doing already.
I have a model State (table states)
column names are id and state

so this in the view works:
<%@states = State.find(:all, :order => "name")
collection_select(:state, :name, @states, :id, :name)
%>

Yet, moving the find to a model , controller or helper is not working.

Am I missing something in everyones responses ?

Re: Question: Help with select tag

I found a solution and not sure if it''s the right one but .......
In the helper for the associated controller:

def liststates
    @states = State.find(:all, :order => "name")
end

Then in the view:

collection_select(:state, liststates, @states, :id, :name)

Re: Question: Help with select tag

Stuart, if you put it into an action called ''state'' in the
controller,
the variable @states is visible only in that action (state)
So, if you access the URL:
http://localhost:3000/controller/state  then @states is visible.

If you want it to be available in the action ''new'', you want
to load the
variable @states before you render the view for it.  that means it needs 
to be a part of the ''new'' action like this:
  def new
    @states = State.find_all
    @clinic = Clinic.new
  end

This way, the @states variable is visible in the view for new.  Does 
this make sense?

As to where it should be moved, "code" within views belongs in
helpers.

Cheers
Mohit.

Re: Question: Help with select tag

That is correct - the only "code" in a view should be stored in a
helper
function.
If you need it more than 1 controller, consider adding it to the 
application helper.

Cheers
Mohit.
