Patch for Plone. Don't raise errors for file contents with missing BLOB file

Project description

How to use

The BLOB support in Plone is amazing for a lot of reasons.

However, right now, Plone will raise errors when you visit a file content that use BLOB support, without having also the BLOB file.

I don’t know if this is good or not (I opened an issue related to this), but for developers this can be a little boring. It’s quite common to copy a production Data.fs for developing something using production data, but you don’t always want to copy all blobs.

This product monkey-patches some points inside Plone, so visiting objects that store content in blob-Fields (like ATFile/ATImage) without its BLOB available will not show any errors to visitors. Instead a file only containing the string “File created by experimental.gracefulblobmissing.” is created in the place where the blob-file should be.


This product also patches the SearchableText Archetypes method, so you can reindex you catalog without errors.


This product has been tested on:

  • Plone 4.0
  • Plone 4.1
  • Plone 4.2
  • Plone 4.3
  • Plone 5.0
  • Plone 5.1
  • Plone 5.2

For Plone 3 compatiblity, look stay on version 0.3.0 or lower.


This is designed only for development/staging environment. Do not use in production if you are not 100% sure of what you are doing!


Developed with the support of S. Anna Hospital, Ferrara; S. Anna Hospital supports the PloneGov initiative.
