syncDef missing [nullable] & comment properties

[Alvalunasan]

Bug Report

Description

function syncDef misses [nullable] flag and field comments for foreign keys fields.

Reproducibility

Include:

• OS MACOS | 12.4
• MATLAB Version 2020a
• MySQL Version 10.2.33-MariaDB
• MySQL Deployment Strategy (remote)
• DataJoint Version 3.5.0
• Minimum number of steps to reliably reproduce the issue

1. Create a table with a foreign key with nullable fields and comments on these fields.

%{
# Defined optogenetic protocols for training
optogenetic_protocol_id   : int AUTO_INCREMENT      # 
---
protocol_description    : varchar(256)         # String that describes stimulation protocol
-> [nullable] optogenetics.OptogeneticStimulationParameter # Stimulation parameters associated with this stim protocol
-> [nullable] optogenetics.OptogeneticWaveform
%}

2. run syncDef over this table.

Expected Behavior

Expected to have [nullable] foreign keys imported correctly. Expected to have imported field comments

Screenshots

Results after syncDef:

%{
# Defined optogenetic protocols for training
optogenetic_protocol_id   : int AUTO_INCREMENT      # 
---
protocol_description    : varchar(256)         # string that describes stimulation protocol
-> optogenetics.OptogeneticStimulationParameter
-> optogenetics.OptogeneticWaveform
%}
