现在,我在python中编写了另一个AI应用程序,用于处理视频(显示在rails应用程序页面的左侧),并使用捕获的车辆及其相应的车牌填充数据库(显示在视频旁边rails app)。意思是说,rails和python应用程序有一个共享数据库。
我现在要做的是,我想刷新右边的部分,比如说每10秒一次,以便显示新添加的车辆。我从这个stack overflow post模式化我当前的解决方案,我能够确认我可以成功渲染js页面,如我的日志中所示:
然而,尽管添加了新条目,部分仍然只显示一个条目。我需要手动刷新页面才能显示所有新条目。我不确定我犯了什么错误。以下是我目前的相关代码:
application.js
//负责部分刷新
$(document).ready(function () {
setInterval(refreshPartial, 1000);
});
function refreshPartial() {
$.get("/single_live.js", function(data){
$("#captured_vehicles_live").html(data);
});
}
static_pages_controller.rb
def single_live
@all_captured_violators = CapturedViolatorPlaceholder.all.order('capture_date DESC')
respond_to do |format|
format.html
format.js
end
end

[正在进行更新]
在尝试应用以下@Matias Seguel的建议后,我现在有了这段代码:
single_live_js.slim
| $("#captured_vehicles_live").html("
= j render 'captured_vehicles_live'
| ");
我还从我的$("#captured_vehicles_live").html(data);
中删除了application.js
,以避免两次渲染我的代码。
application.js
$(document).ready(function () {
setInterval(refreshPartial, 1000);
});
function refreshPartial() {
$.get("/single_live.js", function(data){});
}
答案 0 :(得分:2)
你应该尝试做类似的事情:
single_live.js.slim
$("#captured_vehicles_live").html("<%= j render 'captured_vehicles_live' %>");
或者如果你使用苗条:
| $("#captured_vehicles_live").html("
= j render 'captured_vehicles_live'
| ");
无需再次传递@all_captured_violators。
不要忘记同时移除$("#captured_vehicles_live").html(data);
中的application.js
,以便最终显示:
$(document).ready(function () {
setInterval(refreshPartial, 1000);
});
function refreshPartial() {
$.get("/single_live.js", function(data){});
}
