我曾尝试构建一个 Django Bokeh 应用程序的框架，但无法在单独的线程中选择 bokeh 服务器，因此使用 server_document 构建一个可以发送到 html 页面的脚本。
当我启动Django dev server并进入demo.html页面时，剧情不会出现。我怀疑 Bokeh 服务器可能没有正确启动。但在这里看不到任何解决方案。
demo.py（散景应用程序）
from bokeh.plotting import figure
from bokeh.layouts import column
from bokeh.server.server import Server
def modify_doc(doc):
x_values = [1, 2, 3, 4, 5]
y_values = [6, 7, 2, 4, 5]
# Create a figure object
fig = figure(title='Simple Bokeh Plot', x_axis_label='X-axis', y_axis_label='Y-axis')
# Add a line glyph to the figure
fig.line(x_values, y_values)
# add the plot and slider to a layout and add to the document
layout = column(fig)
doc.add_root(layout)
Bokeh_server = Server({'/': modify_doc})
view.py:
from django.shortcuts import render, get_object_or_404
from django.http import HttpResponse

def demo(request):
script = server_document('http://localhost:5006/')
return render(request, 'tavla/demo.html', {'script': script})
def start_bokeh_server():
Bokeh_server.start()
if __name__ == '__main__':
bokeh_thread = threading.Thread(target=start_bokeh_server)
bokeh_thread.start()
