I would like to know how to make a template call to a field Many to Many of the models.

Follows code:

Models

class Projeto(models.Model):
professor_participante = models.ManyToManyField(Servidor,   verbose_name=u'Professores participante', blank=True)

Views

def projeto(request):
context={}
context['projeto'] = Projeto.objects.all()
return render(request, 'projeto.html', context)

template

{% for projetos in projeto %}
<li>Professor participante - {{ projetos.professor_participante }}</li>
{% endfor %}
django

Both in many-to-many relationships and in many-to-one relationships, one can use them in one for through the suffix .all (the same way you would in Python code proj.professor_participante.all(), only without the parentheses at the end).

{% for projetos in projeto %}
    <ul>
    {% for professor in projetos.professor_participante.all %}
        <li>Professor participante - {{ professor.nome }}</li>
    {% endfor %}
    </ul>
{% endfor %}

Here it is the documentation for calling methods within a template. The only difference is that in this case (Many-to-Many) just use the name of the field, while in a relation of one to many you would have to use the name of the inverse relation (typically entidade_set - unless you have given it a proper name).

P.S. Why are you calling your list from projeto (in the singular) and each individual element of projetos (plural)? I gave the answer according to the question, but the ideal would be to change these names.
