Restart your Flask development server if it hasn’t updated automatically already. Then visit http://127.0.0.1:5000 and verify that Flask serves and renders your base template: Flask rendered the title variable in your website’s title and in the welcome message. Next, you’ll create a page...
By default JinjaFx will fail with "invalid ansible vault password" if the provided Ansible Vault password is empty or missing. Thejinjafx_vault_undefinedvariable allows you to change this behaviour - if set toTruethen it will proceed to process the template, but if it can't decrypt a vaulte...
