Re: [xwiki-users] Livetable counter or unique id?

[Eduard Moraru]

Hi,

I would see a couple of options of doing it yourself:

1) Add an ID property to your class and write a java event listener that
assigns it when a new entry of your class is created.
1.1) Also make sure you customize your sheet to not allow users to modify
that new property (i.e. remove any form element about it or set it hidden).

2) Add an ID property to your class and customize your sheet to add a
hidden form element whose value you prefill with a random value (if one is
not already set).

3) Customize the creation of new entries in your application so that you
can generate a random document name for your entry which you can then use
as ID

etc.

In all cases, you need to make sure that the random ID generated is
sufficiently large to avoid collisions... and an existence check would also
be good before using the generated ID.

Whatever you do, you will still have a theoretical possibility of
collision, since XWiki`s web APIs don`t really allow for transactional
operations. You would have to get down and dirty to make it right, by
having a script service that generates and creates, at the same time,
inside the same transaction the document corresponding to your unique new
entry, which you could then edit. However, if you do the basic checks and
have a large enough random ID, you should be pretty safe in practice.

Hope this helps,
Eduard

FTR someone had published this extension a long time ago:
http://extensions.xwiki.org/xwiki/bin/view/Extension/Unique+Identification+Number+Module

I don’t know its state and I’ve never used it though.

Thanks

Re: [xwiki-users] Livetable counter or unique id?

[Chitnis, Xavier]

Hello,

I work in a hospital information department, and we provide data to many people 
within the organisation. I would like to create a list of requests from users 
for data. Ideally, it would be very helpful if we could assign each record a 
number or ID that we can use elsewhere, e.g. in the SQL queries that we write, 
so that it is easy to go back to the details of a request. We could do this 
manually, but that is obviously prone to error.

The example in the issue Marius linked to would be ideal, if that were possible 
in future.

Kind regards,

Xavier

As Marius said, there’s no counter. However you could use the page full name as 
the unique id (don’t know what your needs are though).

As Marius said, there’s no counter. However you could use the page full name as 
the unique id (don’t know what your needs are though).

There's no automatic / generated counter or id available by default (but it
could be implemented). We have this issue open
http://jira.xwiki.org/browse/XWIKI-7374 , which is related.

[xwiki-users] Livetable counter or unique id?

[Chitnis, Xavier]

Hello,

I am a new user of XWiki and am just starting to explore its functionality. 
I've searched for an answer this question but haven't found anything yet.

I have created an application (which allows me to record details of requests 
received from other parts of my organisation), and have entries displayed in a 
livetable. Is there a way of adding a counter or unique ID field to the 
application and livetable display? This would make it much easier to refer back 
and find entries. I can't see a "doc." property that would enable me to do this.

Many thanks in advance for any assistance.

Xavier
