我能够创建评论以正确的方式进行预订。但是我无法在模态中创建和编辑评论。
我可以在模式中加载新的审阅表单,但只有在书籍已包含审阅的情况下才加载。如果这些书没有评论,则模式按钮将不起作用。
我收到一个我不完全理解的错误
First argument in form cannot contain nil or be empty
指向编辑表单行
<%= form_for([@book, @review], remote: true) do |f| %>
我已经尝试为书籍模型实现模式,该模式可以正常工作,但评论却不能。
books_controller.rb
def show
@reviews = @book.reviews
end
books / show.html.erb
<section id="reviews-section">
<div class="review-form">

在reviews_controller中>编辑操作,您还必须找到@book和@review。
def edit
@review = @book.reviews.find(params[:id])
end
您似乎正在书的显示页面中显示所有评论。并且您想要使用ajax进行编辑。在这种情况下,您必须使用某种循环,并且必须将单个审阅对象分配给任何变量。您需要在表单对象中使用该变量
<%= @reviewes.each do |review| %>
<% form_for [@book, review] ... do %>
...
<% end %>
<% end %>
