Can this be merged or is this already implemented upstream? We're currently pointing our Gemfile to this branch and can't update until uuid primary keys are supported |

@Amnesthesia BTW, it's already possible to specify which columns should be imported. Pass an array of symbols as the first argument to |

@jacob-carlborg-apoex This is for auto-generated UUID columns that are not primary keys :) |
I've added two options for omitting columns from the SQL statements, to avoid having to modify class level `self.ignored_columns` since we've had issues with this affecting other code that runs at the same time. These options work as follows:
`Model.import(values, omit_columns: [:guid])` # Omit the guid column from SQL statement, allowing it to generate
`Model.import(values, omit_columns: -> (model, column_name) { [:guid] if model == Model })` Allow per-model decisions, e.g for recursive imports
`Model.import(values, omit_columns: { Model => [:guid] })` Use a hash instead of a proc
The second option is `:omit_columns_with_default_functions` boolean, to automatically find columns that have a default function declared in the schema, and omit them by default.
fix: Require AR 5.0+
