Question

我使用wice_grid gem和下面的代码。这适用于Rails 4.2.6，但在更新到Rails 5.0.0之后，它给出错误“错误的参数数量（给定0，预期1）”。有人知道如何解决这个问题吗？

<%= grid(@acodes_grid, show_filters: :when_filtered, html: {class: 'my-grid'}) do |g|
  g.column name: 'ID', attribute: 'id', auto_reload: true, html: {id: 'grid-cells'}
  etc.
end %>

相关的控制器方法：

def index
  @acodes_grid = initialize_grid(Acode,
    include:         [:transactions],
    per_page:        25,
    order:           'acodes.code_exp_date',
    order_direction: 'desc')
end

Backtrace（不要认为合并！警告是相关的）：

更新到Rails 5后“错误的参数数量”
