Самовольная параметры: photos_attributes

Question

Я пытаюсь добавить Скрепку к Forem-based Rails app:

Живого приложение: http://runnable.com/VEEnRTEK-igg4XGD/forem-with-paperclip-for-ruby-on-rails

Но почему я получаю Unpermitted parameters: photos_attributes после загрузки?

photo.rb

class Photo < ActiveRecord::Base 
    belongs_to :post, :class_name => "Forem::Post" 
    has_attached_file :attachment, :styles => { 
    :medium => "300x300>", 
    :thumb => "100x100>" 
    } 
    validates_attachment_presence :attachment 
end 

decorators/controllers/forem/topics_controller_decorator.rb

Forem::TopicsController.class_eval do 
    def new 
    authorize! :create_topic, @forum 
    @topic = @forum.topics.build 
    post = @topic.posts.build 
    post.photos.build 
    end 
end 

decorators/controllers/forem/posts_controller_decorator.rb

Forem::PostsController.class_eval do 
    def create 
    @post = @topic.posts.new(post_params) 
    @post.user = forem_user 
    end 

protected 
    def post_params 
    params.require(:post).permit(:text, :password, :email, :photos_attributes) 
    end 
end 

decorators/models/forem/posts_decorator.rb

Forem::Post.class_eval do 
    has_many :photos 

    accepts_nested_attributes_for :photos 
end 

app/views/forem/posts/_post.html.erb

<% for photo in post.photos %> 
    <%= image_tag photo.attachment.url(:medium) %> 
<% end %> 

app/views/forem/posts/_form.html.erb

<%= f.simple_fields_for :photos do |photo| %> 
    <%= render :partial => "photos/form", :locals => { :f => photo }%> 
<% end %> 

app/views/photos/_form.html.erb

<%= f.file_field :attachment, :id => "photo_attachment" %>

Этот ответ просто охватывает ваш вопрос. Ваша ошибка была в имени контроллера. Создание темы осуществляется с помощью Forem :: TopicsController. Это исправленная версия.

#app/decorators/controllers/forem/topics_controller.rb 
Forem::TopicsController.class_eval do 
    def new 
    authorize! :create_topic, @forum 
    @topic = @forum.topics.build 
    post = @topic.posts.build 
    post.photos.build 
    end 
    def create 
    @topic = @forum.topics.new(topic_params) 
    if @topic.save 
     redirect_to @topic 
    else 
     render :new 
    end 
    end 

    protected 
    def topic_params 
     params.require(:topic).permit(:subject, :posts_attributes => [ :text, {:photos_attributes => [:attachment]} ]) 
    end 
end 

Вторая ошибка в отношении самих скрепки. Папка из версии 4 требует проверки типа содержимого. Это исправленная фотомодель.

#app/models/photo.rb 
class Photo < ActiveRecord::Base 
    belongs_to :post, :class_name => "Forem::Post" 
    has_attached_file :attachment, :styles => { 
    :medium => "300x300>", 
    :thumb => "100x100>" 
    } 
    validates_attachment :attachment, presence: true, content_type: { content_type: ["image/jpg", "image/jpeg", "image/png", "image/gif"] } 
end 

Проверьте это на сервере, потому что работоспособные не имеет ImageMagick не установлено, который требуется для вложения скрепки изображения.
