How to send html email with django with dynamic content in it?

Python Programming

Question or problem about Python programming:

Can anyone please help me sending html email with dynamic contents. One way is to copy the entire html code into a variable and populate the dynamic code within it in Django views, but that does not seem to be a good idea, as its a very large html file.

I would appreciate any suggestions.

Thanks.

How to solve the problem:

Solution 1:

Django includes the django.core.mail.send_mail method these days (2018), no need to use EmailMultiAlternatives class directly. Do this instead:

from django.core import mail
from django.template.loader import render_to_string
from django.utils.html import strip_tags

subject = 'Subject'
html_message = render_to_string('mail_template.html', {'context': 'values'})
plain_message = strip_tags(html_message)
from_email = 'From '
to = '[email protected]'

mail.send_mail(subject, plain_message, from_email, [to], html_message=html_message)

This will send an email which is visible in both html-capable browsers and will show plain text in crippled email viewers.

Solution 2:

Example:

from django.core.mail import EmailMultiAlternatives
from django.template.loader import render_to_string
from django.utils.html import strip_tags

subject, from_email, to = 'Subject', '[email protected]', '[email protected]'

html_content = render_to_string('mail_template.html', {'varname':'value'}) # render with dynamic value
text_content = strip_tags(html_content) # Strip the html tag. So people can see the pure text at least.

# create the email, and attach the HTML version as well.
msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.send()

Solution 3:

This should do what you want:

from django.core.mail import EmailMessage
from django.template import Context
from django.template.loader import get_template


template = get_template('myapp/email.html')
context = Context({'user': user, 'other_info': info})
content = template.render(context)
if not user.email:
    raise BadHeaderError('No email address given for {0}'.format(user))
msg = EmailMessage(subject, content, from, to=[user.email,])
msg.send()

See the django mail docs for more.

Solution 4:

For anyone looking at this in 2020 and using django v3.x (I don’t know when this was introduced so it might work for earlier versions.

Note: I only wanted to include an html version without a plain text version. My django view:

from django.template.loader import render_to_string 
from django.core.mail import EmailMessage

# import html message.html file
html_template = 'path/to/message.html'

html_message = render_to_string(html_template, { 'context': context, })

message = EmailMessage(subject, html_message, from_email, [to_email])
message.content_subtype = 'html' # this is required because there is no plain text email message
message.send()

My html file (message.html) looked like this:



 
  
  Order received
  


  
...
content
...

# views.py

from django.http import HttpResponse
from django.template import Context
from django.template.loader import render_to_string, get_template
from django.core.mail import EmailMessage

def email_one(request):

    message = render_to_string('main/email/email.txt', ctx)

    EmailMessage(subject, message, to=to, from_email=from_email).send()

    return HttpResponse('email_one')

def email_two(request):
    subject = "I am an HTML email"
    to = ['[email protected]']
    from_email = '[email protected]'

    ctx = {
        'user': 'buddy',
        'purchase': 'Books'
    }

    message = get_template('main/email/email.html').render(Context(ctx))
    msg = EmailMessage(subject, message, to=to, from_email=from_email)
    msg.content_subtype = 'html'
    msg.send()

    return HttpResponse('email_two')

Solution 6:

If you want dynamic email templates for your mail then save the email content in your database tables.
This is what i saved as HTML code in database =

Hello.. {{ first_name }} {{ last_name }}.
This is an important {{ message }}
By Admin.

Good Day

In your views:

from django.core.mail import EmailMultiAlternatives
from django.template.loader import get_template

def dynamic_email(request):
    application_obj = AppDetails.objects.get(id=1)
    subject = 'First Interview Call'
    email = request.user.email
    to_email = application_obj.email
    message = application_obj.message

    text_content = 'This is an important message.'
    d = {'first_name': application_obj.first_name,'message':message}
    htmly = FirstInterviewCall.objects.get(id=1).html_content #this is what i have saved previously in database which i have to send as Email template as mentioned above HTML code

    open("partner/templates/first_interview.html", "w").close() # this is the path of my file partner is the app, Here i am clearing the file content. If file not found it will create one on given path.
    text_file = open("partner/templates/first_interview.html", "w") # opening my file
    text_file.write(htmly) #putting HTML content in file which i saved in DB
    text_file.close() #file close

    htmly = get_template('first_interview.html')
    html_content = htmly.render(d)  
    msg = EmailMultiAlternatives(subject, text_content, email, [to_email])
    msg.attach_alternative(html_content, "text/html")
    msg.send()

This will send the dynamic HTML template what you have save in Db.

Solution 7:

from django.core.mail import EmailMultiAlternatives

subject, from_email, to = 'hello', '[email protected]', '[email protected]'
text_content = 'This is an important message.'
html_content = '

This is an important message.

' msg = EmailMultiAlternatives(subject, text_content, from_email, [to] msg.attach_alternative(html_content, "text/html") msg.send()

Hope this helps!
