ruby on rails 3.2 - Passing parameter valued to number_field -


the view code passing parameter number field

<%= f.number_field :cap, :value => params[:cap] %>

is not returning parameter, html code attests

<input class=" number_field" id="azienda_cap" name="azienda[cap]" size="30" type="text" value="" />

however, other objects in form (text_field, text_area, collection_select) values being populated url

/aziendas/new?action=show&cap=20081&cognome=j&comune= ...

and debug on params state

cap: "20081"

the api not provide particular clue here

the value should passed second argument of f.number_field, not key-value pair (see http://api.rubyonrails.org/classes/actionview/helpers/formtaghelper.html#method-i-number_field_tag more info)

so, resolve issue, try changing code in view to:

<%= f.number_field :cap, params[:cap] %>
