Odoo10 / Odoo11动态进度条 - 在python中触发javascript函数

Question

My task: a dynamic progress bar in odoo.

I'm using the Odoo widget: 'progressbar'. I want to update the view every time the value is updated - hence I want to trigger the on_change_input javascript function inside my python write method to render the view.

 @api.one
 def updatevalue(self, val):
      self.value = val
      # TODO call javascript function on_change_input()

The purpose is, that the progressbar should be updated while a process is running and the user should see the progress without updating the site.

Is my task possible with the progressbar widget? Or is there another possibility to show dynamic content in Odoo?

If I use my updatevalue method as button, the progressbar is updated after clicking the button without calling the javascript function & without refreshing the page... but I do want to call the method in my code (and probably over rpc) therefore this does not help -.-

Thank you for your time!

Here is the workflow I have so far:

The user clicks on the button do_time_consuming_task and the following function is called:

def do_timeconsuming_task(self):
  ws = websocket.WebSocket()
  ws.connect('ws:/129.0.0.1:1234/')
  data = { 'topic' : 'server_command', 'id' : self.id, 'commandName' : 'do_sth',}
  payload = ujson.dumps(data)
  ws.send(payload)
  ws.close()

On the server, the command is received and processed. There is an open rpc connection:

odoo = odoorpc.ODOO("129.0.0.1", port=8069)
odoo.login("database", "user", "password")
my_module = odoo.env['my_module.progress_widget_test']

progress_instance = my_module.browse(id)

Every time the progress value changes I call the following method of my module:

progress_instance.updatevalue(new_value)

when the value equals 100 % I close the connection

odoo.logout()

This functionality already exists and you can copy parts of it from account/static/src/js/account_reconciliation_widgets.js from the method updateProgressBar and processReconciliations . You will see here the correct way of updating the progress bar.

The purpose is, that the progressbar should be updated while a process is running and the user should see the progress without updating the site.

See on the processReconciliations how it is done, basically you call the process_reconciliations method that exists on the back end and you get a deferred object back. From that deferred object you can use progress()

Looking through the documentation of .progress() you will see that you need to report your progress using .[notify][2]()

How do you define the percentage of completion of your process?
