Django: ManyToManyField appears as empty on my template

[Sergio Madueño]

I'm having an issue displaying a ManyToManyField in a character profile template using Django.

The template has to show an avatar, alongside some information about the character, including a list of guilds this character had joined. But, when I try to display that list, it appears as if it is empty. I had a look into my site administration page, and that information is there, so I have confirmation that the data can be displayed in my template. I just don't know how. How could I handle that?

These are my models:

""" Modelos de la aplicación de personajes """
from django.db import models


class Guild(models.Model):
    """ Modelo del clan """
    guild_name = models.CharField(max_length=25)
    rank = models.PositiveSmallIntegerField()


    def __str__(self):
        return self.guild_name


class Character(models.Model):
    """ Modelo del personaje """
    character_name = models.CharField(max_length=25)
    level = models.PositiveSmallIntegerField()
    race = models.CharField(max_length=25)
    gender = models.CharField(max_length=25)
    job = models.CharField(max_length=25)
    avatar = models.ImageField(upload_to='', blank=True)
    character_guilds = models.ManyToManyField(Guild, blank=True)


    def __str__(self):
        return self.character_name+': '+self.race+' '+self.job+' level '+str(self.level)+'. '

My view.py file:

def characterprofile(request, pk):
    """ Método para mostrar el perfil de un personaje """
    template = '../templates/character/characterProfile.html'
    profile = Character.objects.get(pk=pk)
    guilds = profile.character_guilds.all()
    context = {
        'profile': profile,
        'guilds': guilds
    }
    return render (request, template, context)

And my template.html:

{% extends 'base.html' %}


{% block content %}
    <header>
        <h2>{{ profile.character_name }}'s profile</h2>
    </header>
    <nav class="nav nav-pills nav-justified">
        <a class="nav-item nav-link" href="{% url 'characters' %}">Return</a>
    </nav>
    <br>
    <div class="container">
        <div class="container">
            {% if profile.avatar %}
            <img class="rounded" src="{{ profile.avatar.url }}" width="184" height="184">
            {% else %}
            <p>There is no avatar to display here.</p>
            {% endif %}
        </div>
        <br>
        <h4>Information</h4>
        <ul class="list-group list-group-flush-sm">
            <li class="list-group-item">Name: {{ profile.character_name }}</li>
            <li class="list-group-item">Level: {{ profile.level }}</li>
            <li class="list-group-item">Race: {{ profile.race }}</li>
            <li class="list-group-item">Gender: {{ profile.gender }}</li>
            <li class="list-group-item">Job: {{ profile.job }}</li>
            <li class="list-group-item">
                Guilds:
                {% for g in guilds %}
                    {{ g }}
                {%endfor%}
            </li>
        </ul>
        <br>
    </div>
    <br>
    <footer>

    </footer>
{% endblock %}

Many thanks in advance!
