rails_admin導出沒有運行

Question

我想在rails_admin中使用導出功能。如果我點擊導出按鈕出現以下錯誤：

c:/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/rails_admin-0.6.8/app/views/rails_admin/main/export.html.haml where line #51 raised: 

錯誤的參數數目（0 1）

提取的源（左右線＃51）：

48   %i.icon-chevron-down 
49   = t('admin.export.options_for', name: 'csv') 
50  .form-group.control-group 
51   - guessed_encoding = @abstract_model.encoding 
52   %label.col-sm-2.control-label{for: "csv_options_encoding_to"}= t('admin.export.csv.encoding_to') 
53   .col-sm-10.controls 
54   -# from http://books.google.com/support/partner/bin/answer.py?answer=30990 : 

任何想法如何解決這個問題呢？

Answer 1

我通過註釋線51和56

50 .form-group.control-group 
51 -# guessed_encoding = @abstract_model.encoding 
52 %label.col-sm-2.control-label{for: "csv_options_encoding_to"}= t('admin.export.csv.encoding_to') 
53 .col-sm-10.controls 
54 -# from http://books.google.com/support/partner/bin/answer.py?answer=30990 : 
55 = select_tag 'csv_options[encoding_to]', options_for_select(RailsAdmin::CSVConverter::TARGET_ENCODINGS), include_blank: true 
56 -# %p.help-block= t('admin.export.csv.encoding_to_help', name: guessed_encoding)
