Question

对rails很新，我遇到了错误并且不确定原因。这是整个错误

/Users/aaronmk2/Desktop/CodingDojo/book_review/app/views/books/_form.html.erb:1：语法错误，意外＆＃39;：＆＃39;，期待keyword_end ... pend = simple_form_for @book：html =＆gt; {：multipart =＆gt; true} ... ... ^ /Users/aaronmk2/Desktop/CodingDojo/book_review/app/views/books/_form.html.erb:1：语法错误，意外的keyword_do_block，期待keyword_end ... tml =＆gt; {：multipart =＆gt; true} do |f|@output_buffer.safe_appen ... ... ^ /Users/aaronmk2/Desktop/CodingDojo/book_review/app/views/books/_form.html.erb:10：语法错误，意外的keyword_ensure，期待结束-of-输入

以下是_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 %>

该错误试图寻找关键字end，但我在底部结束了

Answer 1

你忘记了第一行的逗号：

c_int(n).value

Answer 2

您只需添加逗号即可。你的第一行应该是这样的：

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

意外的keyword_do_block期待keyword_end
