Here's how you could create custom error classes in Node.js using latest ES6 / ES2015 syntax.
I've tried to make it as lean and unobtrusive as possible.
errors/AppError.js
| # -*- coding: utf-8 -*- | |
| from django import forms | |
| from crispy_forms.helper import FormHelper | |
| from crispy_forms.layout import Layout, Div, Submit, HTML, Button, Row, Field | |
| from crispy_forms.bootstrap import AppendedText, PrependedText, FormActions | |
| class MessageForm(forms.Form): | |
| text_input = forms.CharField() |
| # List databases | |
| sudo su postgres | |
| psql | |
| \list | |
| # Create a compressed backup | |
| sudo su postgres | |
| pg_dump -Fc <database_name> > <file> | |
| # Example |
| from django.db import models | |
| class Person(models.Model): | |
| name = models.CharField(max_length=200) | |
| groups = models.ManyToManyField('Group', through='GroupMember', related_name='people') | |

| ordering = ['name'] | |
