alter table tabDocField modify column translatable int(1) NULL default 0;
can be used for changing via terminal.
But next I ran into -
pymysql.err.IntegrityError: (1048, u"Column 'allow_in_quick_entry' cannot be null")
Again solved with
alter table tabDocField modify column allow_in_quick_entry int(1) NULL default 0;
Am on master branch frappe + erpnext.
Changes happening in the frappe framework seem to be interfering with
bench update --patch
Now with the above two modifications, the update went through. Sigh!!
