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)

Installation

The package can be installed via:

pip install git+https://github.com/timmyomahony/django-charsleft-widget.git

Usage

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
