Restricting link picker in a doctype to certain folders

[Piyush Mohan]

Hello,

I have a document type in a namespace, which is used inside two channels. That document type has a link(picker) field, which I would like to restrict to a certain folder(one in each channel). Is it possible to do so? If so, directions will be appreciated.


Thx,
Pi

Hi Pi,

I think what you want is not going to be possible.

You can configure the link picker [1] by specifying the UUID or the absolute path. For what you want to work, you'd need to be able to specify a relative path. You can, at least, restrict the picker to the correct document type.

I think I'll create an issue for this improvement.

thanks!

William

Hi William,

we have the same problem, is there any new solution to restrict the link picker to folders in each channel?

thanks,
Philip

What you can do is override the LinkPickerPlugin. This may be a bit complicated and is not something you should do without a good understanding of the cms and Wicket, but is not essentially difficult. It wil lof course introduce a maintenance burden and it may not work across new versions. 

mvg,

Jasper

As Jasper said, you can override the LinkPickerPlugin and change the configuration. I would override the constructor, call super and after that I would modify the config object: config.put("base.uuid", YOUR_UUID);

The challenge I see is that your link picker will need to be aware of the HST channels and their root folders in the content (which is HST information, ideally non accessible from wicket components). I expect you'll either need a mapping somewhere (channel <-> root folder), or read the HST configuration or mark the folders that are roots of channels with some mixin (non recommended, I would keep the content as unaware of this as possible).

The picker by default also remembers the last visited folder, which can be a problem in your case. You'll need to either manipulate that (in the config again) or disable the feature "last.visited.enabled", see https://www.onehippo.org/library/concepts/document-types/configure-the-linkpicker-to-select-folders-or-filter-on-document-type.html

hth!
