Question

我有供应商型号：

 has_many :galleries
has_many :photos, :through=>:galleries
    accepts_nested_attributes_for :galleries

图库模型：

has_many :photos
accepts_nested_attributes_for :photos

照片模特：

    belongs_to :gallery
belongs_to :vendor

在供应商控制器中：

def new
@vendor=Vendor.new(vendor_params)
@vendor.galleries.build.photos.build
end

def vendor_params
params.require(:vendor).permit(galleries_attributes:[photos_attributes:[:photo=>[]]])
end

在vendor / new.html.erb

中

<%= f.fields_for :galleries do |g| %>
<%= g.fields_for :photos do |p| %>
<%= render 'photo_fields', :f=> p %>
<%= link_to_add_association 'Add Photos',f,:photos %>
<% end %>
<% end %>

我收到错误以下错误：
