New Assets not being Added

[cabsports]

Hi There,

I am new to Screenly OSE and I am trying to get setup for a bit of advertising in our club.

I have setup as schedule to add some new assets for a bit of a test. As you can see in the image before I have two assets turned on for a week and and inactive asset "Steak2" setup for 2:45PM until 2:50PM

After 2:45PM the image never shows on the display, below is the log file.

I then go back to the webpage and click on refresh the Asset is moved to being active and it then is shown on the display and in the log file.

Is there something I am doing wrong or is there a bug in the code?

Thanks

@cabsports

I was able to reproduce the bug following your steps.

I noticed that the viewer does not call: Generating asset-list... until after you refreshed the page

I think the bug may be here in viewer.py:

def refresh_playlist(self):
        logging.debug('refresh_playlist')
        time_cur = datetime.utcnow()
        logging.debug('refresh: counter: (%s) deadline (%s) timecur (%s)', self.counter, self.deadline, time_cur)
        if self.get_db_mtime() > self.last_update_db_mtime:
            logging.debug('updating playlist due to database modification')
            self.update_playlist()
        elif settings['shuffle_playlist'] and self.counter >= 5:
            self.update_playlist()
        elif self.deadline and self.deadline <= time_cur:
            self.update_playlist()

Looks like none of those conditions are met for this use case, and thus the playlist is not checked for active assets? In the case of refreshing the page, looks like that probably triggers a database update.

This seems like a common use case, so I think I am missing something. @vpetersson can give more information.

@richard-to

Thanks for that. I have been looking through a bit of the code and the variable "self.deadline" seems to be so far in advance it never triggers the last else if statement.

By looking at the code if I set it to shuffle then it should work, but that is not exactly what I want to do.

[richard-to]

@cabsports

Yeah, that is strange. I wonder how the deadline is calculated. From the log, I assume it would be the earliest end date of your currently enabled and active assets: 2014-07-03 00:39:00, but that is not correct. Could be the dates are stored in GMT/UTC in the database. Yeah, looks like the the playlist only includes currently active assets.

Maybe deadline needs to include enabled and inactive assets? So in that case the deadline should be 2014-06-30 04:45:00 instead. Here for inactive assets, would need to use start date value

[cabsports]

@richard-to

I agree it is only looking at the active assets and it is in UTC time, because my Time Zone is UTC +10 that would make sense.

The deadline date is generated in the "generate_asset_list" procedure using end_date in the playlist.

I think It needs some sort of if statement to check active by end date and non active by start date. What do you think @vpetersson

[brainrake]

The deadline for refreshing the playlist didn't take into account assets starting in the future, only end_dates of assets. This is fixed in the above commit.
The web interface still needs to be refreshed to see the changes, but the screen will display the correct assets.

@brainrape Thank-you so much for fixing this issue so quickly! 👍
