Walter, thanks for helping,

Not sure what you mean I should do, I understand what you're saying,
but
I'm not sure what the 'normal' / simple way to do this is.
This is what I've got in the controller after trying to simplify like
you said:
def multi_params_edit
@events = Event.find( params[:is_ten_event_ids] )
logger.debug("MULTI PARAMS EDIT : " + @events.length.to_s)
@events.each do |e|
logger.debug("trying to make event is_ten_event = true")
e.update_attribute(:is_ten_event, true)
end
redirect_to (:action =>:index)
end
but this does what I was trying to avoid, and when I uncheck the box
and
submit, the attribute is not changed. the check returns! Could you
possibly explain how I should do this in a little more detail please.
It sounds like you're inside a different controller than the
EventsController. Is that true?
Could you set this up with nested attributes?
class Foo
has_many :events
accepts_nested_attributes_for :events
end
class Event
belongs_to :foo
end
#FooController
def update
@foo = Foo.find(params[:id])
if @foo.update_attributes(params[:foo])
redirect_to @foo, :notice => 'Yay'
else
render :action => :edit
end
end
foos/edit.html.erb
<%= form_for @foo do |f| %>
... regular Foo fields here ...
<%= f.fields_for :events do |builder| %>
<%= render "event_fields", :f => builder %>
<% end %>
... rest of the form, including the submit ...
<% end %>
foos/_event_fields.html.erb
... any other Event fields ...
<%= f.check_box :is_ten_event %>
Now Foo can have as many Events as it needs, and each Event can have
an is_ten_event checkbox with the magical un-check ability, and the
controller can take care of everything in one submit, with no extra
effort.
Unless I'm completely missing the point of your domain model, this
should Just Workâ˘.
