Html 意外的关键字\u do\u块应为关键字\u end

刚接触rails，我发现了一个错误，不知道为什么。下面是全部错误

/Users/aaronmk2/Desktop/CodingDojo/book_review/app/views/books/_form.html.erb:1:语法错误，意外的“：”，应为@book:html=>{:multipart=>true}的关键字_end…pend=simple_form_^/Users/aaronmk2/Desktop/CodingDojo/book_review/app/views/books/_form.html.erb:1：语法错误，意外的关键字_do_块，应为关键字_end…tml=>{:multipart=>true}do|f|@output_buffer.safe_appen…^/Users/aaronmk2/Desktop/CodingDojo/book\u review/app/views/books/\u form.html.erb:10:语法错误，意外关键字\u sure，输入应结束

下面是_form.html.erb的代码

<%= simple_form_for @book  :html => {:multipart => true}  do |f|%>
    <%= select_tag(:category_id, options_for_select(@categories), :prompt => "Select a category")%>
    <%= f.file_field :book_img%>
    <%= f.input :title, label: "Book Title" %>
    <%= f.input :description %>
    <%= f.input :author %>
    <%= f.button :submit %>
<% end %>

{:multipart=>true}do | f |%>
“选择类别”）%%>

该错误试图查找关键字end，但我在表单底部有end

您在第一行忘记了逗号：

<%= simple_form_for @book, :html => {:multipart => true}  do |f|%>

{:multipart=>true}do | f |%>

第一行忘记了逗号：

<%= simple_form_for @book, :html => {:multipart => true}  do |f|%>

{:multipart=>true}do | f |%>

您只需添加一个逗号即可。你的第一行应该是这样的：

<%= simple_form_for @book, :html => {:multipart => true}  do |f|%>    

{:multipart=>true}do | f |%>

您只需添加一个逗号即可。你的第一行应该是这样的：

<%= simple_form_for @book, :html => {:multipart => true}  do |f|%>    

{:multipart=>true}do | f |%>
