The form class
Building a form in Django like this:
from django import forms
from tagify.fields import TagField
class TagForm(forms.Form):
languages = TagField(label='languages', place_holder='add a language', delimiters=' ',
data_list=['Python', 'Java', 'PHP', 'Golang', 'JavaScript'], initial='Python Golang')
# or
def random_number():
return [random.randint(10, 19), random.randint(10, 19), random.randint(10, 19), random.randint(10, 19), ]
class NumberForm(forms.Form):
number = TagField(label='number', place_holder='add a number', delimiters=' ',
data_list=random_number)
# or
class TagForm(forms.Form):
languages = TagField(label='languages', place_holder='add a language', delimiters=' ', )
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['languages'].set_tag_args('data_list', get_languages())
The view
To handle the form we need to instantiate it in the view for the URL where we want it to be published:
from django.http import HttpResponse
from django.shortcuts import render
from example.forms import TagForm
def index(request):
if request.method == 'POST':
form = TagForm(request.POST)
if form.is_valid():
return HttpResponse(str(form.cleaned_data['languages']))
else:
form = TagForm()
return render(request, 'index.html', {'form': form})
The template
The simplest example is:
<head>
{{ form.media }}
</head>
<body>
<form action="" method="post">
{% csrf_token %}
{{ form }}
<br>
<input type="submit" value="OK">
</form>
</body>
```python from django.db import models
from tagify.models import TagField
class People(models.Model): name = models.Cha
