166 | | Bear in mind that when reversed this is actually adding a field to a model; |
167 | | if the field is not nullable this may make this operation irreversible (apart |
168 | | from any data loss, which of course is irreversible). |
| 166 | Bear in mind that when reversed this is actually adding a field to a model. To make this possible, Django needs a default value to populate the recreated empty column. This is only possible for a field that is nullable or has a defined default value. |
| 167 | On the other hand if the field is not nullable and does not have a default value, this operation is irreversible (apart from any data loss, which of course is irreversible). |
