Demo: http://forms.viewflow.io/

Installation

django-material tested with Python 2.7/3.4/3.5, django 1.8, django 1.9:

pip install django-material

Forms

Add material into INSTALLED_APPS settings

INSTALLED_APPS = (
     'material',
     ...
)

Include material javascript and styles along with jQuery into your base template.

{% include 'material/includes/material_css.html' %}
<script src="{% static 'material/js/jquery-2.2.0.js' %}"></script>
{% include 'material/includes/material_js.html' %}

Load the material_form template tag library

{% load material_form %}

And render your form with {% form %} template tag

<form method="POST">
    {% csrf_token %}
    {% form form=form %}{% endform %}
    <button type="submit" name="_submit" class="btn">Submit</button>
</form>

Template tags

django-material forms processing is built around simple concept called part. part is like django template block, it has a default value and could be overriden. But parts are created dynamically for each form field, which allows you to redefine specific form field html render output.

Here is the example of rendering form with but prefix email field with email icon.

<form method="POST">
    {% csrf_token %}
    {% form %}
        {% part form.email prefix %}<div class="input-group-addon">@</div>{% endpart %}
    {% endform %}
    <button type="submit" name="_submit" class="btn">Submit</button>
</form>

You can append value to of some tags attribute or completly override the attribute content.

{% form %}
    {% attr form.email 'group' class append %}yellow{% endattr %}
    {% attr form.email 'label' class append %}big{% endattr %}
    {% attr form.email 'widget' data-validate %}email{% endattr %} <!-- by default value would be overriden -->
    {% attr form.email 'widget' placeholder override %}{% endattr %}
{% endform %}

There is a lot of other parts and attribute groups declared in default templates. See template code for details. If your widget is so special, you can completly override its rendering

{% part form.my_field %}any html code here{% endpart %}

Layout

Layout object is the way to specify relative fields placements and sizes.

from material import *

layout = Layout(
    Row('shipment_no', 'description')
    Fieldset("Add to inventory",
             Row(Span3('product_name'), 'tags'),
             Row('vendor', 'product_type'),
             Row(Column('sku',
                        'stock_level',
                        span_columns=4),
                 'gender', 'desired_gender'),
             Row('cost_price', Span2('wholesale_price'), 'retail_price')))

SpanXX elements are not to material grid classes, but used to determine relative fields width. Each row occupies 12 grid columns. Elements in Row(‘elem1’, ‘elem2’) would be rendered in 6 grid coulmns each, and in Row(Span2(‘elem1’), ‘elem2’) elem1 would be rendered in 8 grid columns, and elem2 in 4 grid columns.

Layouts rendering itself is specified in template.

ModelForm Views

Material forms library provides LayoutMixin for model form views, populates form fields list directly from layout object

from django import generic
from viewform import LayoutMixin

class SampleView(LayoutMixin, generic.ModelFormView):
    layout = Layout(...)

---

Frontend

Frontend template assumes that your application contains a set of top level modules each one could restrict user access level and have own submenu.

To quick start add material.frontend into INSTALLED_APPS settings

INSTALLED_APPS = (
     'material',
     'material.frontend',
     ...
)

Add frontend urls into global urlconf module at urls.py

from material.frontend import urls as frontend_urls

urlpatterns = [
    ...
    url(r'', include(frontend_urls)),
]

The fronend module perform all required settings modification (add middleware, context_processors and template tags), automagically till MATERIAL_FRONTEND_AUTOREGISTER settings set to False.

To create a new module add ModuleMixin to your AppConfig definision in apps.py

from material.frontend.apps import ModuleMixin

class Sales(ModuleMixin, AppConfig):
    name = 'sales'
    icon = '<i class="mdi-communication-quick-contacts-dialer"></i>'

The application have to have <app_module>/urls.py file, with a single no-parametrized url with name=’index’, ex

urlpatterns = [
        url('^$', generic.TemplateView.as_view(template_name="sales/index.html"), name="index"),
]

All AppConfigs urls will be included into material.frontend.urls automatically under /<app_label>/ prefix The AppConfig.label, used for the urls namespace.

The menu.html sample

<ul>
    <li><a href="{% url 'sales:index' %}">Dashboard</a></li>
    <li><a href="{% url 'sales:customers' %}">Customers</a></li>
    {% if perms.sales.can_add_lead %}<li><a href="{% url 'sales:leads' %}">Leads</a></li>{% endif %}
</ul>

Admin

Add material.admin into INSTALLED_APPS settings

INSTALLED_APPS = (
     'material',
     'material.admin',
     ...
)

NOTE: ‘material.admin’ must be added before ‘django.contrib.admin’

Ensure that django.template.context_processors.request in your template context processor settings list

TEMPLATES = [
    {
        ...
        'OPTIONS': {
            'context_processors': [
                ...
                'django.template.context_processors.request',
                ...
            ],
        },
    },
]

You can provide a custom admin site module in the MATERIAL_ADMIN_SITE setting

MATERIAL_ADMIN_SITE = 'mymodule.admin.admin_site'

Admin support development is on initial stage. Only basic admin features are available.
