Send_email in django with data from a view as an HTML page

Question

Im having a hard time with this. I have a view like this:

@login_required
def verFactura(request, id_factura):
    fact = Factura.objects.get(pk = id_factura)
    cliente = Cliente.objects.get(factura = fact)
    template = 'verfacturas.html'
    iva = fact.importe_sin_iva * 0.21
    total = fact.importe_sin_iva + iva

    extra_context = dict()
    extra_context['fact'] = fact
    extra_context['cliente'] = cliente
    extra_context['iva'] = iva
    extra_context['total'] = total

    return render_to_response(template, extra_context)

that takes data from the databse and do some math and shows it on a template like this:

<div class="row">
    <div class="col-xs-12">
        <div class="box">
            <div id="">
                <p id="address">
                    {{fact.nombre_cliente}}
                </p>
                <p id= "numero">
                    {{fact.numero_De_Factura}}
                </p>
                <div id="logo">
                    <img id="image" src="{% static 'img/Home/Logo-Exisoft.png' %}"                 alt="logo" />
                </div>
            </div>

            <div style="clear:both"></div>

            <div id="customer">
                <div id="datos">
                    <p id = "direccion">
                        {{cliente.Direccion}}
                    </p>
                    <br>
                    <p id = "direccion">
                        {{fact.RI}}
                    </p>
                </div>
                <table id="meta">
                    <tr>
                        <td class="meta-head">Fecha</td>
                        <td><textarea id="date">{{fact.fecha_factura}}</textarea></td>
                    </tr>
                    <tr>
                        <td class="meta-head">CUIT</td>
                        <td><div class="due">{{cliente.CUIT}}</div></td>
                    </tr>
                </table>
            </div>

            <table id="items">
                <tr>
                    <th class="tipo">Tipo de Factura</th>
                    <th class="descripcion">Descripcion</th>
                    <th>Precio</th>
                </tr>
                <tr class="item-row">
                    <td><div><textarea>{{fact.tipo_Factura}}</textarea></div></td>
                    <td class="description"><textarea>{{fact.descripcion}}</textarea></td>
                    <td><span class="price">$ {{fact.importe_sin_iva}}</span></td>
                </tr>
             </table>
             <table id="totales">
                    <tr>
                        <td class="total-line">Subtotal</td>
                        <td class="total-value"><div id="subtotal">$ {{fact.importe_sin_iva}}</div></td>
                    </tr>
                    <tr>
                        <td class="total-line">Iva</td>
                        <td class="total-value"><div id="total">$ {{iva}}</div></td>
                    </tr>
                    <tr>
                        <td  class="total-line">Precio Pagado</td>
                        <td class="total-value"><textarea id="paid">$ {{total}}</textarea></td>
                    </tr>
              </table>

              <div id="terms"></div>        
        </div><!-- /.box-body -->
    </div><!-- /.box -->
</div>

so what this does is go to the view and renders the information for the fields and completes them, pretty simple. The thing is that when the user creates a bill (Factura in spanish) i also save the data from fields like {{iva}} and {{total}} into the database, so i have this information in two places: database and the template. OK. So what i want to do is to send an email with proper HTML (hopefully this same tables that appear in the template). Because this information is different for every bill (Factura) i can´t send and email with static information, it has to show the information of each of the bills.

So how can i do this?. Take the info from the database and change the value that appears between the tags to show the correct information for each bill.

Thank you in advance. I would really appreciate the help or any idea that points me in the right direction. Thank you

You can use the built-in django send_mail method. You'll see how to send HTML emails as well.

The better solution is to use django_templated_email app which uses the normal django templates to allow you to compose rich HTML emails that it will send out.

It has a very simple API:

from templated_email import send_templated_mail
send_templated_mail(
        template_name='welcome',
        from_email='from@example.com',
        recipient_list=['to@example.com'],
        context={
            'username':request.user.username,
            'full_name':request.user.get_full_name(),
            'signup_date':request.user.date_joined
        },
        # Optional:
        # cc=['cc@example.com'],
        # bcc=['bcc@example.com'],
        # headers={'My-Custom-Header':'Custom Value'},
        # template_prefix="my_emails/",
        # template_suffix="email",
)

To use it in your view, follow these steps:

1. Install the library pip install django_templated_email .
2. Create a templates directory in the same directory that you have views.py for your application.
3. Inside this templates directory you created, create another directory called templated_email . Your template emails will go here.

Now, create a file in this templates/templated_email directory called receipt.email

Copy and paste the following into it:

{% block subject %}Your Receipt # {{fact.numero_De_Factura}}{% endblock %}

{% block html %}
<html>
<head>
<title>Receipt</title>
</head>
<body>
<table>
  <thead>
    <tr><th>Receipt Number</th><tr><th>Client Number</th></tr>
  </thead>
  <tbody>
    <tr><td>{{fact.numero_De_Factura}}</td><td>{{fact.nombre_cliente}}</td></tr>
  </tbody>
</table>
</html>
{% endblock html %}

{% block plain %}
  Thank you. Your receipt number is: {{fact.numero_De_Factura}} and your client # is {{fact.nombre_cliente}}
{% endblock plain %}

You can adjust the HTML to your liking and even inherit from other templates. Make sure you keep the special {% block html %} and {% block subject %} as this is how the application will create your HTML email and its subject.

Finally, to send the email is the easiest part. Just a few lines in your existing view method:

from django.shortcuts import render
from templated_email import send_templated_mail

@login_required
def verFactura(request, id_factura):
    fact = Factura.objects.get(pk = id_factura)
    cliente = Cliente.objects.get(factura = fact)
    template = 'verfacturas.html'
    iva = fact.importe_sin_iva * 0.21
    total = fact.importe_sin_iva + iva

    extra_context = dict()
    extra_context['fact'] = fact
    extra_context['cliente'] = cliente
    extra_context['iva'] = iva
    extra_context['total'] = total

    # Send the email
    send_templated_mail(template_name='receipt',
                        from_email='robot@server.com',
                        recipient_list=[request.user.email],
                        context=extra_context)

    return render(request, template, extra_context)
