以下_receipt_number
个部分(为简洁起见,删除了HTML格式标记)
<%= turbo_frame_tag :receipt_number do %>
<%= t('scan') %> <%= t('cart.receipt_number') %>
<h3><%= @cart.receipt_number %></h3>
<% if @cart.receipt_number %>
<%= button_to t('change'), clear_receipt_number_cart_path(id: @cart.id), class: 'button warning', method: :patch %>
<% end %>
<% end %>
在HTML中呈现为:
<turbo-frame id="receipt_number">
scan receipt number
<h3></h3>
</turbo-frame>
通过控制设备摄像头的Java脚本运行并处理扫描(这是该实例的相关Java脚本代码)
let formData = new FormData();
let CodeParams = {
code_data: result.text,
id: <%= @cart.id %>
};
formData.append("code_json_data", JSON.stringify(CodeParams));
fetch("update_receipt_number", {
method: "post",
format: "turbo_stream",
body: formData,
headers: {
"X-CSRF-Token": document.querySelector("[name='csrf-token']").content,
}
});
codeReader.reset();
通过控制器操作执行以下操作:
@cart.update(receipt_number: result['code_data'])
respond_to do |format|
format.turbo_stream
end
日志(log)显示了操作处理,但是without a format pre-defined for the contorller和渲染所需的对象:

</turbo-frame>
</template></turbo-stream>
然而,浏览器窗口不会更新.
我不认为控制器没有请求类型是起作用的,因为响应到达浏览器.那么,为什么浏览器不刷新turbo_Frame?the same was attempted with a div in lieu of the turbo_frame, leading to identical behaviour
我遗漏了什么?
