Comment (by Simon Charette): I just wanted to mention that wrapping your migration operations with `SET CONSTRAINTS ALL IMMEDIATE` solves the `pending trigger events` message. {{{#!python operations = [ migrations.RunSQL('SET CONSTRAINTS ALL IMMEDIATE', 'SET CONSTRAINTS ALL DEFERRED'), migrations.AlterField( model_name='charity', name='name_legal', field=models.CharField(max_length=255, default='', verbose_name='legal name'), preserve_default=False, ), migrations.RunSQL('SET CONSTRAINTS ALL DEFERRED', 'SET CONSTRAINTS ALL IMMEDIATE'), ] }}} Maybe this is something that could be done automatically by Django in `AlterField` when it knows it has to perform both a data and structural update? -- Ticket URL: <https://code.djangoproject.com/ticket/25492#comment:7> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
