Online document preview for older file versions

Seafile Server
1

Hi Seafile Community!

I recently noticed something interesting: I can preview documents like .doc, .xlsx, .pdf online in seahub, but when I choose “view” for an older version of the same file at the file history window, it says:
"Online view is not applicable to this file format".
Same thing happens when I attempt to view online any document while browsing a library snapshot.

Is that mean online file preview is not implemented for “file history browsing” or maybe I forgot to configure something? I checked the logs for error messages, but nothing showed up related to office file conversations.

I use Seafile pro edition 7.1.14, deployed with docker (multi container setup), sitting behind nginx reverse proxy.

my seafevents.conf:

[DATABASE]
type = mysql
host = db
port = 3306
username = seafile
password = ***
name = seahub_db



[AUDIT]
enabled = false

[INDEX FILES]
external_es_server = true
es_host = elasticsearch
es_port = 9200
enabled = true
interval = 10m


highlight = fvh

## If true, indexes the contents of office/pdf files while updating search index
## Note: If you change this option from "false" to "true", then you need to clear the search index and update the index again. See the FAQ for details.
index_office_pdf = false

[OFFICE CONVERTER]
port = 6000
host = 127.0.0.1
enabled = true
workers = 1

[SEAHUB EMAIL]
enabled = false

## interval of sending Seahub email. Can be s(seconds), m(minutes), h(hours), d(days)
#interval = 30d

# Enable statistics
[STATISTICS]
enabled=true

My seahub-settings.py:

# -*- coding: utf-8 -*-
SECRET_KEY = ******
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'seahub_db',
        'USER': 'seafile',
        'PASSWORD': *****
        'HOST': 'db',
        'PORT': '3306'
    }
}


CACHES = {
    'default': {
        'BACKEND': 'django_pylibmc.memcached.PyLibMCCache',
        'LOCATION': 'memcached:11211',
    },
    'locmem': {
        'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
    },
}
COMPRESS_CACHE_BACKEND = 'locmem'
TIME_ZONE = mylocation
FILE_SERVER_ROOT = "https://seafile.mydomain.com/seafhttp"

EMAIL_USE_TLS = True
EMAIL_HOST = ***
EMAIL_HOST_USER = *****
EMAIL_HOST_PASSWORD = *****
EMAIL_PORT = 587
DEFAULT_FROM_EMAIL = ****
SERVER_EMAIL = *****

OFFICE_CONVERTOR_ROOT = 'http://127.0.0.1:6000/'

ENABLE_RESUMABLE_FILEUPLOAD = True

Can anyone confirm whether this is a normal/expected behavior?

It is likely online file preview does not work for old versions.

Thanks for the quick reply @daniel.pan !

Is there any plans to implement this feature in the future?

(Regardless of this I am very happy with your product, it contains so many useful features that are not present in other self hosted solutions!)

Regards,
Sam

do you use LibreOffice?

and if so, with or without a license?

do you use LibreOffice?

A far as I know I use the converter which was provided by the docker image seafile-pro-mc:7.1.14
I just enabled office converter in the config files. So yeah if Libreoffice is the default program for that, then yes.

and if so, with or without a license?

You mean the Seafile Professional server? I use seafile-pro without license, because my “Organization” consists of two users currently. :grinning:
