我正在尝试从我的控制器操作中渲染一些东西。
def show
@bookmark = Bookmark.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @bookmark }
end
end
以上是控制器中的操作。
show 的 html erb 文件是：
<p>
<b>Url:</b>
<%= @bookmark.each do |book| %>
<li><%= book.url%>
<b>Title:</b>
<li><%= book.title%>
<% end %>
</p>
我也得到了输出，但除此之外，我得到了额外的东西。输出是：
Url:
www.google.com Title:
h
www.gmail.com Title:
hiw
asd Title:

sd Title:

我最后应该摆脱数组打印。我只想打印记录。
