Ruby on rails Rails是否在控制器中保存草稿更新?
我有一个名为articles的模型,它有一个字符串字段,允许用户将文章设置为草稿。当选择了草稿并且用户更新了文章时,我希望它返回到文章编辑页面,就像用户选择了发布选项一样,然后我希望用户被重定向到文章索引页面 问题是,如果选择了草稿选项,我无法更新文章并将其重定向回帖子。我是不是走错了路 迁移文件Ruby on rails Rails是否在控制器中保存草稿更新?,ruby-on-rails,ruby,ruby-on-rails-3,Ruby On Rails,Ruby,Ruby On Rails 3,我有一个名为articles的模型,它有一个字符串字段,允许用户将文章设置为草稿。当选择了草稿并且用户更新了文章时,我希望它返回到文章编辑页面,就像用户选择了发布选项一样,然后我希望用户被重定向到文章索引页面 问题是,如果选择了草稿选项,我无法更新文章并将其重定向回帖子。我是不是走错了路 迁移文件 def change add_column :articles, :status, :string, default: 'Draft' end 文章.rb scope :submitte

如果您确实希望使用1/2的值 型号:
STATUS_VALUES = {1 => "Draft", 2 => "Published"}
scope :submitted, lambda { where('status = ?', STATUS_VALUES[2]) }
scope :draft, lambda{ where('status = ?', STATUS_VALUES[1]) }
attr_accessible :_status
after_initialize do
self.draft! if self.new_record? # be draft by default
end
def draft!
self.status = STATUS_VALUES[1]
end
def published!
self.status = STATUS_VALUES[2]
end
def _status
STATUS_VALUES.invert(status)
end
def _status=(value)
case value
when 1, "1" then self.draft!
when 2, "2" then self.published!
else self.draft!
end
end
def draft?
self.status == STATUS_VALUES[1]
end
def published?
self.status == STATUS_VALUES[2]
end
控制器:
def update
@article = article.find(params[:id])
if @article.update_attributes(params[:article])
flash[:notice] = "Successfully Updated"
if @article.draft?
respond_with(@article, :location => edit_article_path)
else
respond_with(@article, :location => articles_path)
end
else
render :action => :edit
end
end
视图:
<%= f.check_box(:_status, "Published", 2, 1) %>
