The Emancipator

[iuravic]

The data for this migration is already in a WP database. All the stuff I run in this code is looking at the large serialized array in post_meta (with the key api_content_element).

Here is what goes on:

• We remove the categories "opinion" and "the-emancipator" and make sure the categories nested under them now has a parent of 0 instead of the deleted categories
• We add co-authors as the byline
• We grab descriptions of co-authors from the post content and delete it from post content after.
• We add post subtitles.

I also added a few functions to the logic in this repo. Most notably I added a generator function get_all_wp_posts that should be a little less agressive on memory than using get_posts.

How to test

(I've just been running on local)

# Empty the trash
wp post delete $( wp post list --post_status=trash --type=post_type --format=ids )

wp newspack-content-migrator emancipator-taxonomy
# wp newspack-content-migrator emancipator-authors
wp newspack-content-migrator emancipator-bylines
wp newspack-content-migrator emancipator-post-subtitles
# wp newspack-content-migrator emancipator-redirects

There are two commands commented out – those I still need some input on.

I'm not sure how much/little to log, so it's a bit all over the place :)

OK, I've been playing around with the co-authors and have a function that massages them into place. It still needs some work, so I'll continue on Monday.

I've been playing around with getting more data. We have three commands so far for this migration". They all use data from the big serialized api_content_element in the post metadata.

wp newspack-content-migrator emancipator-authors
wp newspack-content-migrator emancipator-redirects
wp newspack-content-migrator emancipator-post-subtitles

1. The first one gets author(s) and adds them as co-authors. I'm not sure where the post authors in the dataset come from, but they have emails something like AmberPayneandDeborahDouglas@bostonglobe.com for instance. I found a field that seems to have the original owner/poster of the article with an email sorta like deborah.douglas@globe.com. We could use those as the user? They are in $api_content_element['revision']['user_id'].
2. A bunch of articles on the live sites are redirects. I've migrated them to entries with John Godley's redirect plugin. Not sure if that's what we want, but it's a shot :)
3. The post subtitles are added from the $api_content_element['subheadlines']['basic'] field.

There are still TODOs in the code

@iuravic I can't add you as the reviewer since you originally posted this one, but it's ready for review :)

This ran on a staging clone. I'll merge so future changes are easier to keep track of.
