I've came across an issue where message is displayed twice even though its called only once. Sometimes only one message is displayed however, most of the time 2 messages are.
My view:
def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
form.save()
messages.success(request, f'Account created has been creted! You can log-in now.')
return redirect('login')
else:
if request.user.is_authenticated:
messages.error(request, 'You are loged-in and in order to registrate you must be loged-out.')
return redirect('blog-home')
else:
form = UserRegisterForm()
return render(request, 'users/register.html', {'form': form,'title':'Register Page'})
And here is my template:
Base.html
{% load static %}

</html>
You can see that in the {% if messages %} block, message is called only once.
And here is the main html:
{% extends "blog/base.html" %}
{% block content%}
{% for post in posts %}
<article class="media content-section">
<div class="media-body">
<div class="article-metadata">
<a class="mr-2" href="#">{{ post.author.first_name }}</a>
<small class="text-muted">{{ post.date_posted|date:"d F, Y"}}</small>
</div>
<h2><a class="article-title" href="#">{{ post.title }}</a></h2>
<p class="article-content">{{ post.content }}</p>
</div>
</article>
{% endfor %}
{% endblock content%}
Any ideas what could be causing this?
