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.
from django import forms
from charsleft_widget.widgets import CharsLeftInput
from .models import Song
class SongForm(forms.ModelForm):
name = forms.CharField(widget=CharsLeftInput())
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 = SongFormYou can optionally toggle off the color changing feature by initialising the widget (from the example above) with:
name = forms.CharField(widget=CharsLeftInput(attrs={'change_color': False}))
