Messages not appearing after creating an app for it in Django

[Ahmed Khairy]

I created an app called marketing app which customizes messages to be written 
on top of website page. My problem is that these messages are not showing when 
everything is configured and I don't know why is that might be the template 
because {{ marketing_message.message}} is only not showing

This is the model of the Marketing App

class MarketingMessage(models.Model):
    message = models.CharField(max_length=120)
    active = models.BooleanField(default=False)
    featured = models.BooleanField(default=False)
    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
    updated = models.DateTimeField(auto_now_add=False, auto_now=True)
    start_date = models.DateTimeField(
        auto_now_add=False, auto_now=False, null=True, blank=True)
    end = models.DateTimeField(
        auto_now_add=False, auto_now=False, null=True, blank=True)

    def __str__(self):
        return str(self.message[:12])

this is the views for the core app:

class HomeView(ListView):
    model = Item
    paginate_by = 10
    template_name = "home.html"

    def get_context_data(self, **kwargs):
        context = super(HomeView, self).get_context_data(**kwargs)
        context['marketing_message'] = MarketingMessage.objects.all()

this is the template:
{% if marketing_message %}
    <div class="alert alert-light" style="padding-top:80px; 
margin-bottom:-24px">
        <a href="#" class="close" data-dismiss="alert">×</a>
        <div class="container" style="text-align:center">
        <strong>Marketing Message ! : </strong> {{ marketing_message.message}}
        </div>   
    </div>
{% endif  %}

This is the admin.py of marketing

from django.contrib import admin
from .models import MarketingMessage
# Register your models here.


class MarketingMessageAdmin(admin.ModelAdmin):
    class Meta:
        model = MarketingMessage


admin.site.register(MarketingMessage, MarketingMessageAdmin)


        return context
