A simple django widget that appends a character count to a text input which is determined by the max_length of that particular field. This only works on text inputs and not text areas (as they don't respect max_length anyway)
The package can be installed via:
pip install git+https://github.com/timmyomahony/django-charsleft-widget.git
For the most common usage, first create a model:
from django.db import models
class Song(models.Model):
title = models.CharField(max_length=100)then create a custom model form that uses the custom widget class. Note that it's important
to include the maxlength attribute manually when making use of the widget, as it will not
be pulled in automatically from your model field.
from django import forms
from charsleft_widget.widgets import CharsLeftInput
from .models import Song
class SongForm(forms.ModelForm):
name = forms.CharField(widget=CharsLeftInput(attrs={'maxlength': 100}))
class Meta:
model = Song
fields = "__all__"If you are using it in the Django admin, import your custom model form in your ModelAdmin:
from django.contrib import admin
from .models import Song
from .forms import SongForm
@admin.register(Song)
class SongAdmin(admin.ModelAdmin):
form = SongForm
