The new partial varies just a little from the original contents of posts/index. First, we'll use the local variable posts
in place of the instance variable @posts
.
Second, because we're rendering this from outside the directory app/views/posts
, we need to be more specific when rendering slug
and actions
.
New file: _app/views/posts/list.html.erb
<ul class="posts">
<% posts.each do |post| %>
<li>
<%= render 'posts/slug', post: post %>
<%= render 'posts/actions', post: post %>
</li>
<% end %>
</ul>
Back in posts/index, we'll render our new partial, assigning the required local variable.
app/views/posts/index.html.erb
<%= render 'list', posts: @posts %>
Then we'll render it in categories/show.
app/views/categories/show.html.erb
<% sidebar(@category.sidebar) -%>
<div class="category">
<h2><%= @category.title %></h2>
<div class="description"><%= @category.description %></div>
<%= render 'posts/list', posts: @category.posts %>
</div>
If you haven't already, create a few catgories, and associate a few posts to each. If they look right, let's commit what we have.
You're still taking a look at git status
and/or git diff
before each commit, right?
$ git add .
$ git commit -m "Display posts by category."
