I forgot to add the routes.
namespace :admin do
resources :categories do
resources :words
end
end
I have a nested form from a namespaced resource...
Word.rb
class Word < ApplicationRecord
belongs_to :category
has_many :choices
accepts_nested_attributes_for :choices
validates :content,presence: true, length: { maximum: 20 }
end
Choice.rb
class Choice < ApplicationRecord
belongs_to :word
validates :content, presence: true, length: { maximum: 20 }
validates :word_id, presence: true
validates :correct, presence: true
end
words_controller.rb
def new
@word = Word.new
3.times {
@word.choices.build
}
end
def word_params
params.require(:word).permit(:content, choices_attributes: [:id, :content, :correct])
end
Word new.html.erb
<div class="container mt-4">
<div class="row">
<div class="col-lg-6 offset-lg-3">
<%= form_for([:admin, @word.category]) do |f| %>

<%= f.text_field :content, class: 'form-control', placeholder: 'Word' %>
</div>

<div class="form-group">
