Python3 and Dexterity upgrade notes

Plone 5.1 / Python 2.7

Create new DX CT's: Newletter, Newsletter Issue, Newletter Subscriber
Add DX schema fields mostly like the current AT fields

Differences

Newsletter

Schema

old : new

senderEmail : sender_email
senderName : sender_name
testEmail : test_email
contentAggregationSources : content_aggregation_sources
default_header : default_prologue
default_footer : default_epilogue
excludeAllSubscribers : exclude_all_subscribers
outputTemplate : output_template
template : aggregation_template

Behaviors

Newsletter: Plone users/groups as recipients
Newsletter: External subscriber sources
Newsletter: External delivery services

Newsletter Issue

Schema

old : new

Behaviors

Newsletter: Plone users/groups as recipients
Newsletter: Collection as source [make sure existing Collections have the behavior set with values]
Implement CT's methods mostly as views/utilities instead of instance methods
Move aggregation templates into a behavior for Collections, so that every selected collection can have a different aggregation template. This makes the ENLTemplate CT obsolete.
Upgrade step: Hide AT CT's from Menu
Upgrade step: Migrate AT content to DX
Upgrade step: Migrate subscriber portlets to use the new DX objects
Upgrade step: Remove old AT content
