Ruby on Rails的MySQL的不返回結果

Question

當我拿到書的數據，它沒有返回值

這裏是list.html.erb文件

<table border="1"> 
    <tr> 
      <th>ISBN</th> 
      <th>Name</th> 
      <th>price</th> 
      <th>publish</th> 
      <th>published</th> 
    </tr> 
<%= "asdf" %> 
<% @books.each do |book| %> 
<%= "asdf" %> 
    <tr> 
      <td><%= book.isbn %></td> 
      <td><%= book.title%></td> 
      <td><%= book.price%></td> 
      <td><%= book.publish%></td> 
      <td><%= book.published%></td> 
    </tr> 
<% end %> 
</table> 

，並在這裏是fm_controller.rb

... 
    def list 
      @books = Book.all 
      @booksCount = Book.count 
      puts @books 
      puts @booksCount 

    end 
end 

如果您需要更多信息，我會盡快更新。幫我...

（編輯詳細信息） 服務器日誌打印這樣

@bookCount打印0，但MySQL表有1行。這裏是我的查詢結果

select * from book; 

+------+-------+-------+---------+-----------+ 
| isbn | title | price | publish | published | 
+------+-------+-------+---------+-----------+ 
| 1111 | asdf | 1233 | sasdf | asdf  |

1 row in set (0.00 sec) 

Answer 1

SELECT * FROM books收益爲零 但SELECT * from book返回1個對象。 製作你的餐桌書。
Book.all從書籍表格而非書籍表格中提取記錄。
