Form_tag + fields_for Rails 4

Rails
1

Hi There,
I’m trying to user fields_for inside a form_tag, but i can’t catch
it
on my controller.

I just take some html code off to makes it easy to read

my view…

i’m using campuses_path(current_church, @campus) instead form_for
@campus, because my route is like
resources :campuses, :path => “:church/campuses”

<%= form_tag campuses_path(current_church, @campus), :class =>

<% end %>

<% end %>

my controller

  • @campus.addresses.new(params[:addresses]) # the error line*
    list through.
    def campus_params
    params.require(:campus).permit(:name, :description, :cover,
    :addesses)

    i’ve tried instead :addresses

    {:addresses => []}

    :addresses []

end

end

my model

class Campus < ActiveRecord::Base

belongs_to :church
has_many :addresses, :as => :addressable

accepts_nested_attributes_for :addresses

end

Request parameters

{“utf8”=>“✓”,
“authenticity_token”=>“B0OBKKM3PQ/Jkh1ebcKyrKZGJuauJeN3O/BWv8Vc7qE=”,
“campus”=>{“name”=>“Campus name”, “description”=>“campus description”},
“addresses”=>{“street”=>“Street name”, “street2”=>"", “city”=>“city
name”, “state”=>“state name”, “zip_code”=>“00000”}, “action”=>“create”,
“controller”=>“campuses”, “church”=>“greenhouse-church”}

Params at Controller:

params[:addresses]
=> {“street”=>“Street name”, “street2”=>"", “city”=>“city name”,
“state”=>“state name”, “zip_code”=>“00000”}

params[:campus]
=> {“name”=>“Campus name”, “description”=>“campus description”}

With this code the error is:

ActiveModel::ForbiddenAttributesError

@campus.addresses.new(params[:addresses])

Let me know if you need more information.

Thank You,

André

Have you tried with form_for instead of form_tag?

(accepts_nested_attributes_for)

The parameters being submitted aren’t the same as if you had done

<%= form_for @campus do |form|%>
<%= form.fields_for(:addresses) do |addresses_form| %>
…
<% end %>
<% end %>

For one, addresses is being submitted at the top level, not nested.
params[:campus][:addresses] would be a hash of hashes (one hash for each
address). If you’re dead set on use form_tag,

<%= fields_for @campus do |form|%>
<%= form.fields_for(:addresses) do |addresses_form| %>
…
<% end %>
<% end %>

should do it

Params at Controller:

params[:addresses]
=> {“street”=>“Street name”, “street2”=>"", “city”=>“city name”, “state”=>“state
name”, “zip_code”=>“00000”}

params[:campus]
=> {“name”=>“Campus name”, “description”=>“campus description”}

Because params[:addresses] is a hash, you need to permit the individual
keys in it (much as you have to permit the individual campus keys)
