to connect my document management system with erpnext, I created a doctype called ecoDMS.
If I want to connect the document #21 with e.G. an Invoice, I create a document of the type ecoDMS with the number 21. Over a custom script all the metadata gets imported into the document.
In addition to the metadata, I create a preview of the document, and attach it as a jpg to ecoDMS-document in erpnext.
Now I want to show the attached image.jpg in the form:
So where the ‘missing image’ symbol is shown, the attachment should be displayed.
I do not want the user to upload any attachments. It should only show the page-one preview, that was uploaded via the API on item_creation.
