AtoM loads too many digital objects

[Isabel Martín]

The following code included in .... / plugins / sfIsadPlugin / modules / sfIsadPlugin / templates /:

<? php slot ('before-content')?>
  <? php echo get_component ('digitalobject', 'imageflow', array ('resource' => $ resource))?>
<? php end_slot ()?>

It loads all the scanned documents of a file archive as well as those of all its children.

I have created funds with sub-funds that contain a large amount of scanned documents. 
When using the get_component, it reviews all the documents of all the subfunds children,
which are thousands which causes it to take a long time to load.

Is it possible to load only the scanned documents corresponding to a description, 
ignoring those of the child sub-funds? and in case the father does not have his own digitized documents, 
do not show any.

a greeting

Hi Isabel, 

The purpose of the carousel is to offer users a way to browse the lower-level digital objects - it does not show descriptions associated with the current level. See: 

• https://www.accesstomemory.org/docs/latest/user-manual/access-content/navigate/#recurring-carousel 

In version 2.4 and higher, you can disable the carousel via Admin > Settings > Default page elements if you don't want it to display. See: 

• https://www.accesstomemory.org/docs/latest/user-manual/administer/settings/#default-page-elements  
  

Note as well that, while AtoM will attempt to fetch a count of lower-level digital objects, the number of thumbnails it loads into the carousel viewer is determined by the global setting for results per page. See: 

• https://www.accesstomemory.org/docs/latest/user-manual/administer/settings/#results-per-page  
  

If you wanted to modify the carousel to show only immediate children, and not all digital object descendants, then you will need to make code changes. I am not personally able to advise you on what these should be, but I can at least point you in the right direction. 

The carousel uses a code library called ImageFlow (which I believe I have mentioned to you in previous threads), so that is what you'll want to search for in the code repository. Here is the template for the page component: 

• https://github.com/artefactual/atom/blob/qa/2.5.x/apps/qubit/modules/digitalobject/templates/_imageflow.php 

There are two places where I would recommend beginning your investigations. First, it appears that the criteria for fetching thumbnails to be added to the carousel is being set here: 

• https://github.com/artefactual/atom/blob/qa/2.5.x/apps/qubit/modules/digitalobject/actions/imageflowComponent.class.php#L44-L48 

There is also a function called getDescendantDigitalObjectCount, here, that is currently looking for all descendants, rather than just immediate child descriptions with digital objects:

• https://github.com/artefactual/atom/blob/qa/2.5.x/lib/model/QubitInformationObject.php#L1424-L1435  
  

Those two pages should give you a good starting point for investigation!

Good evening, Dan, thank you very much for your prompt response. It has been a great help to me although I still have enough things to adjust.

Thanks for all. Greetings.
