ruby on rails - one view two controllers -


my app got installation controller , address controller.

address has_one :installation , installation belongs_to :address

in installation view, got simple_form inside in other simple_form. this:

<%= simple_form_for @installation, class: 'form-horizontal' |f| %>     <%= f.error_notification %>          <%= f.simple_fields_for @installation.address |u| %>               <%= u.label :street_address, label: t('address.address_label'), required: true, class: 'col-sm-2 control-label' %>                 <%= u.input_field :street_address, class: 'form-control'                 %>

so how can update 2 models ?

can have 2 def params ? likes this:

def installation_params     params.require(:installation).permit(x) end  def installation_address_params     params.require(:????).permit(y) end

you can use nested attributes.

untested, roughly:

model:

class installation < activerecord::base   belongs_to :address    accepts_nested_attributes_for :address end

and in installationscontroller:

params.require(:installation).permit(...,   address_attributes: [:id, ...])

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
