[英]How to render all instances with an id from another model?
I have a model :folder that belongs to :user and takes a user_id. 我有一个属于:user的模型:folder并带有一个user_id。 A user can create as many folders as they want, and the homepage renders all folders that have the user_id of the current user. 用户可以创建任意数量的文件夹,并且主页呈现具有当前用户的user_id的所有文件夹。 However, using this code on the homepage: 但是,在首页上使用以下代码:
<ol class="folders-vertical">
<%= render @folders %>
</ol>
with this instance variable in the homepage controller: 在主页控制器中使用以下实例变量:
@folders = current_user.folders
It also renders the :folder model itself. 它还会渲染:folder模型本身。 So, each user's first folder is the :folder model instead of the actual first folder they create. 因此,每个用户的第一个文件夹是:folder模型,而不是他们创建的实际第一个文件夹。 How can I avoid rendering this? 我如何避免呈现此内容?
您可以使用如下形式:
@folders = Folder.where(user_id: current_user.id).drop(1)
