Question

我建立了一個表格，允許您內聯編輯記錄； 我遇到的問題是部分數據在視圖中刷新后不會重新渲染數據。 我正在使用單獨的 controller 來處理更新/編輯部分渲染。 我可以成功地內聯呈現表單，我只是無法通過更新部分錯誤而沒有收到未定義的局部變量。 如何在不同的 controller 中重新渲染我的 update.js.erb 操作的部分？

編輯.js.erb

document.getElementById('<%= dom_id(@facility_event_tracker) %>').insertAdjacentHTML('afterend', "<%= j render 'inline_form', facility_event_tracker: @facility_event_tracker %>");

更新.js.erb

document.getElementById('<%= dom_id(@facility_event_tracker, 'inline_form') %>').remove()

Rails 控制台錯誤

// 部分無法重新渲染以進行更新

ActionView::Tempalate::Error (undefined local variable or method `event' for #<#<Class:0x00000>:0x00005>):

Answer 1

您似乎只將update.js.erb文件傳遞給facility_event_tracker object 而不是事件 object：

document.getElementById('<%= dom_id(@facility_event_tracker, 'inline_form') %>').innerHTML = <%= j render "facility_event_trackers/facility_event_tracker", facility_event_tracker: @facility_event_tracker %>"

我建議您添加：

document.getElementById('<%= dom_id(@facility_event_tracker, 'inline_form') %>').innerHTML = <%= j render "facility_event_trackers/facility_event_tracker", facility_event_tracker: @facility_event_tracker, event: @event %>"
