I have a form that uses two models - badge and badge winners. The user_id and community_id fields are needed for badge_winners which is nested in badges. I was trying to learn from Ryan Bates’ Railscast (http://railscasts.com/episodes/196-nested-model-form-part-1)
The error I’m getting is:
ActiveRecord::UnknownAttributeError in BadgesController#create
unknown attribute: user_id
app/controllers/badges_controller.rb:42:in `new’
LIne 42 corresponds to this line in :create
@badge = Badge.new(params[:badge])
here’s the controller:
def new
@badge = Badge.new
badge_winner = @badge.badge_winners.build
respond_with(@badge)
end
def create
@badge = Badge.new(params[:badge])
if @badge.save
flash[:notice] = “Badge was successfully created.”
redirect_to home_path
else
flash[:notice] = “There was a problem creating your badge.”
redirect_to home_path
end
end
Here’s the form (both community_id and user_id are populating fine):
<%= form_for(@badge) do |f| %>
<%= f.label :Description %>
<%= f.text_area :description %>
<%= f.fields_for :badge_winners do |builder| %>
<%= builder.hidden_field :user_id ,:value => user_id %>
<%= builder.hidden_field :community_id ,:value => community_id %>
<% end %>
<%= f.submit “Give Badge” %>
<% end %>
The models (user_id and community_id are fields in the BadgeWinner table):
class Badge < ActiveRecord::Base
belongs_to :community
has_many :badge_winners, :dependent=>:destroy
accepts_nested_attributes_for :badge_winners
end
class BadgeWinner < ActiveRecord::Base
belongs_to :user
belongs_to :badge
end
I’m hoping someone’s able to help. I just know it’s a newbie error somewhere. Thanks in advance for any assistance!
