aruseni / fields.py
Created February 8, 2017 16:23
This is a TextField-based field with TextInput widget. This can be used instead of a CharField whenever you do not want to restrict the length of the content at the DB level (see http://stackoverflow.com/questions/4848964/postgresql-difference-between-text-and-varchar-character-varying for more info).
from django.db import models
from django import forms
class TextInputTextField(models.TextField):
def formfield(self, **kwargs):
kwargs.update({
"widget": forms.TextInput
})

Last active April 13, 2016 09:58
This Django model mixin adds an incr_count method that increments the “count” field in one SQL query (very useful if same object can be updated simultaneously and you want the count field to have correct values).
class CountIncrMethodMixin(models.Model):
def incr_count(self):
model = type(self)
model.objects.filter(id=self.id).update(
count=models.F("count")+1
)
