Question

你好，我需要使用attr_accessible或類似that.And我是新的Ruby on Rails的

這是我post.rb文件

class Post < ActiveRecord::Base 
    has_many :comments 

    attr_accessible :body, :title, :published, :author, :author_id 
    belongs_to :author, :class_name => "AdminUser" 


    validates_presence_of :body,:title 
    scope :published, where(:published => true) 

    def content 
    MarkdownService.new.render(body) 
    end 

    def author_name 
    if author 
     author.name 
    else 
     "Nobody" 
    end 
    end

Answer 1

你需要使用Strong Params此：

#app/models/post.rb 
class Post < ActiveRecord::Base 
    has_many :comments 
    belongs_to :author, :class_name => "AdminUser" 

    validates_presence_of :body,:title 
    scope :published, where(:published => true) 

    def content 
    MarkdownService.new.render(body) 
    end 

    def author_name 
    if author 
     author.name 
    else 
     "Nobody" 
    end 
    end 


end 

#app/controllers/posts_controller.rb 
def new 
    @post = Post.new 
end 

def create 
    @post = Post.new(post_params) 
end 

private 

def post_params 
    params.require(:post).permit(:body, :title, :published, :author, :author_id) 
end
