我在Rails 4中遇到了Chartkick时间轴图表的问题 . 当页面加载时，抛出此错误：
“＃Array：...>的未定义方法`each_pair'”
在Chartkick代码中如下所示;
def chartkick_deep_merge(hash_a, hash_b)
hash_a = hash_a.dup
hash_b.each_pair do |k, v|
tv = hash_a[k]
hash_a[k] = tv.is_a?(Hash) && v.is_a?(Hash) ? tv.deep_merge(v) : v
end
hash_a
end
我尝试使用to_json，as_json，@ events.each do ...，@ events.map ...尝试的时间轴（“chart-1”，“phase_masters_phase_time_path”）进行各种代码迭代，指向渲染json：Events . select（：id，：event_types，：starttime，：endtime）.where（project_masters_id：params [：proj_id]，phase_masters_id：params [：id]）
变量似乎正确设置，如hash_b中所示
hash_a
{:width=>"400px", :height=>"400px", :colors=>["#B9D3EE", "#9FB6CD", "#A2CD5A", "#6E8B3D", "#FFB90F", "#E3A869"]}
hash_b
[[#<Events id: 1, event_types: "Estimating", starttime: "2015-10-05 11:15:00", endtime: "2015-10-13 21:15:00">], [#<Events id: 2, event_types: "Roll Forming", starttime: "2015-09-09 11:00:01", endtime: "2015-09-16 18:29:59">], [#<Events id: 7, event_types: "Magest On Site", starttime: "2015-09-25 11:00:01", endtime: "2015-09-25 18:29:59">]]
view:
<div id = "chart-1"> </div>
<%=
timeline("chart-1", @events.map { |evnt| [evnt] } )
%>
controller:
@events = Events.select(:id, :event_types, :starttime, :endtime).where(project_masters_id: params[:proj_id], phase_masters_id: params[:id])
respond_to do |format|
format.html
format.json {render json: @events}
end
任何有助于此运行的帮助将不胜感激 .

看起来你将
Events数组传递给方法timeline，该方法需要一个三元组数组（类型为数组） .我正在阅读你的代码，但似乎对
timeline的调用可能就像是timeline("chart-1", @events.map { |evnt| [evnt.types, evnt.starttime, evnt.endtime] })
