Rails - Aug 2009 - how do you access params that are both model based and non model based?

Hi all

Ive got a form thats based on a model that I need to put a drop down
box and additional text field to build the description for the item.

heres some quick code

View

<%= form_for (@shape) do |f| %>
<%= f.text_field :description %>
<%= select_tag "shape_name",
"<option>round</option><option>square</
option><option>triangular</option>" %>
<%= text_field_tag "shape_code" =>


Controller

@shape.new
@shape.description = params[:description]
@shape.shape = "#{params[:shape_name]} #{params[:shape_code]}"
@shape.save

What happens is I get the shape.shape set right (to the name from the
select box and the code from the text field) but description is always
empty,

Heres whats in the params when I do a raise shape.to_yaml to debug it.

{"shape_name"=>"triangular",
 "shape_code"=>"shape code is here",
 "order"=>{"description"=>"this is a
description"}
"shape_code"=>"342",
 "shape_number"=>"111",
 "finish1"=>"Silver",
 "commit"=>"Create",


Can someone point out how I should be accessing the params so I can
set the description of the shape?

Many thanks

Hi all

Apologies first of all if this it the third time of seeing this, I posted
previously but didn''t see it on the googlegroup archive or current
discussions.

Ive got a form that''s based on a model that I need to put a drop down
box and additional text field to build the description for the item.

heres some quick code

View

<%= form_for (@shape) do |f| %>
<%= f.text_field :description %>
<%= select_tag "shape_name",
"<option>round</option><option>square</
option><option>triangular</option>" %>
<%= text_field_tag "shape_code" =>


Controller

@shape.new
@shape.description = params[:description]
@shape.shape = "#{params[:shape_name]} #{params[:shape_code]}"
@shape.save

What happens is I get the shape.shape set right (to the name from the
select box and the code from the text field) but description is always
empty,

Heres whats in the params when I do a raise shape.to_yaml to debug it.

{"shape_name"=>"triangular",
 "shape_code"=>"shape code is here",
 "order"=>{"description"=>"this is a
description"}}

Can someone point out how I should be accessing the params so I can
set the description of the shape?

Many thanks

@shape.description = params[:order][:description]

Many thanks for that!  Just what I needed to know.  I thought I tried that,
but I guess I didnt.

Along the same lines how about when Ive got a select_date on the form?  The
data comes back in the params as
{stuff => "something",
order=> {"thedate(3i)" =>"2009",
"thedate(2i)" => "10",
"thedate(1i)" => "1"}}

Ive tried

param[:order][:thedate](3i)
and
params[:order][:thedate(3i)]

and a load of other ways that are definately wrong!  Ive also looked through
the ruby book and the agile ruby on rails book, but not sure what to look
for so cant help myself here.

Can someone point me in the right direction?

Many thanks

To post a followup.  So the archive is here.

Seems the problem is when not doing mass assignment active record does the
date object creation.

This blog post
http://blog.springenwerk.com/2008/05/set-date-attribute-from-dateselect.htmlexplains
is much better than I can but lets say it solves it.

So updating a date or datetime field in a model from params yourself is not
easy but can be done with the above link

(thats for the search next time!)

Thanks to all that helped on this.

Hi all,
I have two fields in a form.
One text field non asociated to the model for the user type a value. the 
view is:
<%= text_field_tag ''item_cod'','''', :size
=> 3 %>

Other a field with a select list with codes, names for the user select 
from. The view is:

<%= f.select :item_id, Item.select_list, :size => 40 %>

item_id is the real field of my model.

I want the following behavior.
1. If the user type a code into the text_field tag -> Update the list so 
the user view the corresponding name of the item they type.
2. If the user select from the list -> Update the text field with the 
code corresponding to the name selected. (this is the easy part)

My form works fine with one Observe field for the :item_id list but I 
can''t do work the point 1.

Thanks in advance,
FF

Please don''t hijack threads.  It will hide your problem, and will not
endear you to folks on most mailing lists, including this one.

Best regards,
Bill

Because you''re using form_for it prefixes the form element names with 
the model name.  Which in your case must not be Shape, but Order, seeing 
that params[:order][:description] contains the description.

That is how you access the value by the way: 
params[:order][:description]

Honestly though, I''m really not sure why the description is going into 
params[:order], is Order really the model name?  I''m going to assume 
so...

Here''s a brief, potentially correct explanation of how this all works.

<input name="order[description]" ... />

This gets pulled into the params hash as params[:shape][:description]. 
Following this naming convention for your form items (or using f.select 
and f.text_field with form_for) will give you the ability to use this 
syntax:

@order = Order.new(params[:order])
@order.save
