  • Mass relate / unrelate

    Hello there

    I've built some custom actions for contacts / leads whereby I can add or remove them from one or more target lists from their list views.

    This works fine, however I'd like to make use of the 'Select All' and where method too. In the source code there's already a dialog which supports massRelate, and so a massUnRelate should not be so tricky. However when relating / unrelating from the child entity's list view we'd need to somehow specify what the scope is (target list / etc) before opening the dialog.

    E.g list contacts by a where condition, choose Select ALL, from the action menu choose Mass Link or Mass Unlink, then in the sub menu choose the Entity Type, then Select Records dialog opens, and you can select one or more entities (also possibly using Select All and/or Where options).

    Example of how this might look:



    Do you have suggestions on how best to achieve this? We need this feature really soon, and so for now will use my Target List specific hack but it would nicer to make the process work with any relatable foreign entity.

    If anyone wants this functionality now you can use this https://github.com/alasdaircr/espocr...a5e19e317913f6 however it would be great to get this into a place as a viable pull request.

    Hi

    It's better to make it the same as Mass Update. Dialog shows up and you select Link Name you want to update.

    I'm going to add this feature in future.

      Ok so I could get this working and submit as a PR. My main trouble was with mass unrelating, I added the extra functions to ORM/DB/Mapper.php etc but I needed to add a hack to allow a DELETE FROM when passing lists of IDs rather than passing a where clause to a DELETE FROM x JOIN. I basically did it in two calls, first SELECT the Ids, then DELETE them. It works for me, but I think with huge numbers of IDs the DELETE FROM call would fail.

        Some necro-context about a long DELETE query: every SQL batch has to fit in the batch Size Limit: 65,536 * Network Packet Size

      I wouldn't bother about it. When do Mass Update there are very many queries are run to perform an access check. (2*n) is not a big deal in your case. Anyway it's important to check ACL for 'delete' action.

        I'm checking ACL for edit action on the entity which is being unrelated from (e.g. the Target List) in the same way as the relate calls. I don't check for ACL on the contacts/leads.

        I'l push the changes up to github later on

          BTW you can use Reports to populate Target Lists.

            Yeah I know - but it would be good to have this as a built in feature for all entities
