How to Use DjangoCMS Transfer - TACC/Core-CMS GitHub Wiki

Purpose

Recreate or Save plugin configuration on pages even across different CMS projects.

Instructions

  1. Watch djangocms-transfer README video.
  2. Import/Export plugins to achieve your task.

Gotchas

It does not support foreign key relations and won't import/export related data. — djangocms-transfer Readme

This means that users should delete images (and other media) before exporting. See Workarounds.

Workarounds

  • Before export, remove images (and other media) from the page Structure.
  • After export, remove media entries from the .json (remove entire object).
  • After export, remove foreign key relations from the .json (change any "internal_link"'s to null).
  • After export, fix any snippet references (ensure desired snippet exists, then change "snippet"'s to correct ID).

Use Cases

Replicate Frontera Homepage to Create Sandbox for Testing Major Changes

@tacc-wbomar, to backup instances removed by FP-1360, used this plugin to export all Article List/Preview instances (sans media) (with snippets) from https://dev.fronteraweb.tacc.utexas.edu. He performed all of the workarounds, then imported the instances to his local standalone CMS instance. When all workarounds are performed, there are no errors.

This plugins-frontera-home-2021-03-with-plugins--mod-for-import.zip includes two JSON files: one before workarounds, and one after workarounds.

  7. Import plugins to instance B.
  8. ✓ Expect success.
Detailed Steps

If "High-Level Steps" is too high-level, please try this instead:

  1. Be able to Test CMS Changes across multiple CMS instances. Both need:
    • Either this branch, test/djangocms-transfer.
    • Or an image built from this branch, taccwma/core-cms:e64b689 (job).
  2. (On local CMS) In both CMS's docker containers, run pip install -r requirements.txt.
  3. On CMS instance A, login to CMS admin.
  4. Create page.
  5. Create "Text" plugin instance.
  6. Create "Image" plugin instance (with uploaded image).
  7. Create snippet plugin instance (with a created snippet).
  8. Export plugins (see [djangocms-transfer README] video).
  9. On CMS instance B, login to CMS admin.
  10. Create page.
  11. Import plugins (see [djangocms-transfer README] video).
  12. ⓧ Expect failure, because of "Gotchas".
  13. Perform all "Workarounds" (export again if necessary).
