Django Python if block on template file (string)

Question

I am trying to ad a condition into an html model in Django (python) and it is not working:

This is my HTML:

                    <p class="card-text text-muted h6">{{ post.author }} </p>
                    {% if post.author  == 'John_Woo' %}
                    <p class="card-text text-muted h6"> NOK </p>
                    {% else %}
                    <p class="card-text text-muted h6"> ok </p>
                    {% endif %}

Not sure what is wrong here... Even though I have a John_Woo author, I only get ok message

This is my models.py:

class Post(models.Model):
    title = models.CharField(max_length=200, unique=True)
    slug = models.SlugField(max_length=200, unique=True)
    author = models.ForeignKey(User, on_delete= models.CASCADE,related_name='blog_posts')

This is my views.py:

from django.views import generic
from .models import Post

class PostList(generic.ListView):
    queryset = Post.objects.filter(status=1).order_by('-created_on')
    template_name = 'index.html'

class PostDetail(generic.DetailView):
    model = Post
    template_name = 'post_detail.html'

Almost certainly, author is a ForeignKey, so it will never equal a string. But show your model. — Daniel Roseman

Post.author returns class's representation like(str, unicode, repr) function. You have to override this functions which is depends on your django version. But you have one way to compare this. Like if Post.author.first_name == "John_Woo"

You want post.author.name (where .name is whatever field of an User object that will sometimes contain the string 'John_Woo' )
