I have a form used to create a ''Style''. The style may have any
number of
''features'' which correspond to ''Feature''
models in the features table. I
would like to add the appropriate entries to a relationship table
(''stylefeatures'') whenever a Style is created. Here is a
breakdown of my
models:
class Style < ActiveRecord::Base
has_many :stylefeatures
has_many :features, :through => :stylefeatures, :foreign_key =>
:feature_id
accepts_nested_attributes_for :stylefeatures
end
class Feature < ActiveRecord::Base
has_many :stylefeatures
has_many :styles, :through => :stylefeatures, :foreign_key => :style_id
end
class Stylefeature < ActiveRecord::Base
belongs_to :style
belongs_to :feature
accepts_nested_attributes_for :features
end
...and here is my controller for the ''new'' action:
def new
@style = Style.new
@features = Feature.all
end
...and here is my form:
<%= simple_form_for @style, :html => { :class =>
''form-horizontal'' } do |m| %>
<%= m.simple_fields_for :features do |p| %>
<%= p.input :name, :label => "Features", :collection =>
@features,
:input_html => { :multiple => true } %>
<% end %>
[....]
<% end %>
Right, so the list of features DOES load up into the multiple select box
within my form. So that''s sweet. However, when I go to submit I receive
the
error: No association found for name ''features''. Has it been
defined yet?
I get the exact same error when adding @style.features.build to the
controller ''new'' action.
This is what the params hash looks like. It carries the ID of the feature
name selected.
"features"=>{"name"=>["","7"]}
So my question is, how do I go about loading the features listed in the
features table for the nested form, and on form submission, handle the
selected features for addition to the stylefeatures relationship table.
Thanks very much

Colin, thanks for your response. I have moved a bit further on my original
problem of updating the through table.
I now have in my *controller*:
def new
@style = Style.new
@style.stylefeatures.build
@features = Feature.all
end
def create
@style = Style.new(params[:style])
@style.stylefeatures.build
@style.save
end
...and in my *style* *model*
*
*
attr_accessible :stylefeatures_attributes
has_many :stylefeatures
has_many :features, :through => :stylefeatures, :foreign_key =>
:feature_id
accepts_nested_attributes_for :stylefeatures
... and in my *stylefeature model*
belongs_to :style
belongs_to :feature
accepts_nested_attributes_for :feature
... and in my *feature model*
attr_accessible :description, :fullname, :name
has_many :stylefeatures
has_many :styles, :through => :stylefeatures, :foreign_key => :style_id
... and in my *create form*
<%= m.simple_fields_for :stylefeatures do |p| %>
<%= p.input :feature_id, :label => "Features", :collection
=>
@features, :input_html => { :multiple => true } %>
<% end %>
Now when I save the new Style, the stylefeatures table is updated with the
appropriate style_id, but with two useless entries. The first is an array
with all of the feature ids which have been selected in the form. The
second is a blank entry with the appropriate style_id and nothing in the
feature_id column.
Do you have any clue of what I might be doing wrong, or how to spread the
collected feature_id''s into the table as desired?
Thanks,
Abram
