I'm experimenting with a Django 1.4.6 project for tracking sales leads. I want this to be mobile-friendly, so I'm using Twitter Bootstrap (still on version 2.3.2) with django-crispy-forms. According to this article, the best way to do e-mail fields is <input type="email" autocapitalize="off" autocorrect="off">
and the best way to do date fields is <input type="date">
. None of these attributes are implemented by default with Django and I'm wondering how best to go about implementing them. Here is the relevant code (simplified):
models.py
from django.db import models
class Lead(models.Model):
name = models.CharField(max_length=50)
email = models.EmailField(blank=True, null=True)
initial_contact_date = models.DateField()
class Meta:
ordering = ('name',)
def __unicode__(self):
return self.name
views.py
from django.core.urlresolvers import reverse
from django.views.generic import CreateView, ListView, UpdateView
from .models import Lead
class LeadAdd(CreateView):
model = Lead
def get_context_data(self, **kwargs):
context = super(LeadAdd, self).get_context_data(**kwargs)
context['title'] = 'Add a Lead'
return context
def get_success_url(self):
return reverse('lead_list')
class LeadEdit(LeadAdd, UpdateView):
def get_context_data(self, **kwargs):
context = super(LeadEdit, self).get_context_data(**kwargs)
context['title'] = 'Edit a Lead'
return context
class LeadList(ListView):
model = Lead
urls.py
from django.conf.urls import patterns, url
from .views import *
urlpatterns = patterns('',
url(r'^$', view=LeadList.as_view(), name='lead_list'),
url(r'^add/$', view=LeadAdd.as_view(), name='lead_add'),
url(r'^edit/(?P<pk>[\d]+)/$', view=LeadEdit.as_view(), name='lead_edit'),
)
lead_form.html
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block content %}
<div class="page-header">
<h1>{{ title }}</h1>
</div>
<form action="." method="post" class="form-horizontal">
{% csrf_token %}
{{ form|crispy}}
<div class="form-actions">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
{% endblock content %}
Use a field template to do this (see the docs on Field):
Field('email', template="custom-email.html")
OR create a custom widget. There is an abstract class you can use, but one of the existing predefined widgets should work:
# widgets.py
from django.forms.widgets import TextInput
class EmailInput(TextInput):
input_type = 'email'
So it might look like this in your view:
class LeadAdd(CreateView):
model = Lead
form_class = LeadAddForm
...
And then that LeadAddForm class would have your custom widget defined:
from . import widgets
LeadAddForm(forms.Form):
email = forms.CharField(
...
widget = widgets.EmailInput,
...
)
Or you can set the widget in the init:
class LeadAddForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(LeadAddForm, self).__init__(*args, **kwargs)
self.fields['email'].widget = widgets.EmailInput()
You should be able to set the extra attributes (autocapitalize="off" autocorrect="off") using the crispy form config:
Field('email', autocapitalize="off", autocorrect="off")
The simpler option:
forms.py
:
class LeadForm(forms.ModelForm):
class Meta:
model = Lead
def __init__(self, *args, **kwargs):
super(LeadForm, self).__init__(*args, **kwargs)
self.helper = FormHelper()
self.helper.form_class = 'form-horizontal'
self.helper.layout = Layout(
Fieldset('Enter the following information',
'name',
Field('email', type="email",
autocapitalize="off",
autocorrect="off"),
Field('initial_contact_date', type="date")),
FormActions(
Submit('save', 'Create Lead'),
Button('cancel', 'Cancel')
)
)
In your views.py
:
class LeadAdd(CreateView):
model = Lead
success_url = reverse('lead_list')
form_class = LeadForm
def get_context_data(self, **kwargs):
context = super(LeadAdd, self).get_context_data(**kwargs)
context['title'] = 'Add a Lead'
return context
class LeadEdit(LeadAdd, UpdateView):
def get_context_data(self, **kwargs):
context = super(LeadEdit, self).get_context_data(**kwargs)
context['title'] = 'Edit a Lead'
return context
In your template:
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block content %}
<div class="page-header">
<h1>{{ title }}</h1>
</div>
{% crispy form %}
{% endblock content %}
