意外的keyword_do_block預期的keyword_end

Question

Rails的新手，出現錯誤，不確定原因。 這是整個錯誤

/Users/aaronmk2/Desktop/CodingDojo/book_review/app/views/books/_form.html.erb:1：語法錯誤，意外出現“：”，期望出現keyword_end ... pend = simple_form_for @book：html => {：multipart => true} ... ... ^ /Users/aaronmk2/Desktop/CodingDojo/book_review/app/views/books/_form.html.erb:1：語法錯誤，意外的keyword_do_block，期望keyword_end ... tml => {：multipart => true}做|f|@output_buffer.safe_appen ... ... ^ /Users/aaronmk2/Desktop/CodingDojo/book_review/app/views/books/_form.html.erb:10：語法錯誤，意外的keyword_ensure，預期輸入結束

這是_form.html.erb的代碼

<%= 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 %>

錯誤試圖尋找關鍵字結尾，但我在表格的底部

Answer 1

您在第一行忘記了逗號：

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

Answer 2

您只需要添加一個逗號。 您的第一行應如下所示：

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