yes it works. but the Delete button is ugly. Is it possible to use only public buttons: Create, Edit, Delete selected items?

good work.

I reopen this issue for two reasons:

1. The table Admin - Quota uses Bold font, should be normal font.
2. There should be an nfs quota item, i.e., the disk size the user can have in their global data directory.

I just tested your code, sadly it failed.

Two problems:

1. The data field should have a default value, e.g., 100. Currently it is blank.
2. Can not change default group. Get error message

simplejson.scanner.JSONDecodeError
simplejson.scanner.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

1.You can set the value of data in admin page, Is this a problem? I will add default value in upgrade.py later.
2.This problem due to PedroLiu rewrite the httprest.py, I use getvalue method of form before, now should be get, I will fix it soon.
3.About the Bold font, I don't know why it is Bold. I write it the same as other table, but only admin page has this problem.

1. A default value is better.
2. About upgrade.py, I think it is a bit professional. But, it could be more professional. For example, check the version of original system and determine the upgrade actions. Since we will have many releases, there should be many upgrade actions, each could be very different. This could be done in the future.

About the commits of #89 , the docklet.conf.template could be changed to the following.

# DATA_QUOTA : whether enable the quota of data volume or not
# True or False, default: False
# DATA_QUOTA=False

# DATA_QUOTA_CMD : the cmd to set the quota of a given directory. It accepts two arguments:
# arg1: the directory name, relative path from the data volume root, e.g, "/users/bob/data"
# arg2: the quota value in GB of string, e.g., "100"
# default: "gluster volume quota docklet-volume limit-usage %s %s"
# DATA_QUOTA_CMD="gluster volume quota docklet-volume limit-usage %s %s"

Also you need to change code accordingly, especially NO changed to False, YES changed to True
