The goal of slc.dublettefinder is to find duplicate files (dublettes ;) in the ZODB and then warn the user via validation error during content edit/creation.
slc.dublettefinder is a Plone product plugin that warns you of possible file duplications in your Plone website.
It provides custom validators (that can be ignored with a checkbox on the form) that warns the user if the file or image being uploaded is a possible duplicate of a file already in the site.
It also provides a portlet that will show any possible file duplications when on the context of any file or image.
Works with the ATContentTypes ATFile and ATImage as well as Blobs.
Validators are run when an object is newly created or being edited. They are used to for example check that the fields of the object where correctly filled in.
slc.dublettefinder registers three new validators for the main two file containing objects (ATFile and ATImage), and you can easily register them for your own file containing objects. See ./extensions/configure.zcml
The validators are called isUniqueObjectName, isUniqueFileName and isUniqueFileSize and can be found in ./validators.py.
The first validator check the object’s Title against all other objects of the same type in the database, and warns you if there is a match.
The second validator checks the uploaded file’s name against files in the database and the third validator checks the file’s size.
All three validators will warn you if they find a match, and then allow you to override them (by clicking a checkbox) and continue adding your object.
A custom portlet is also provided, that will show you any possible duplicates of the object/context that you are currently viewing.
