升级到 Rails 2.3.11 后,我不能再使用 SlickGrid 创建我们所谓的数据集。如果单击切换图标来创建数据集,我会得到以下堆栈跟踪:

这是 slick_data.rb 中的“to_data_json”代码:
def to_data_json
new_data = sanitized_data.map do |d|
h = {}
h['data_set_name'] = d.name
j = 1
d['values'].each do |v|
h["var_#{j}"] = v
j += 1
end
h
end
ActiveSupport::JSON.encode(new_data)
end
这是 data_sets_controller.rb 中“索引”的代码:
def index # Ajax
@scenario = Scenario.find(params[:scenario_id])
sd = SlickData.new(@scenario.data_sets)
render :json => {
:html => render_to_string(:layout => false,
:template => 'data_sets/index.html.erb',
:object => @scenario),
:id => @scenario.id,
:data => sd.to_data_json,
:columns => sd.to_col_json,
}
end
我可能需要升级我的 json gem 吗?我正在使用 1.4.6。或者也许我需要升级我的 SlickGrid 版本?我使用的是 1.4.3 版。谢谢。
