{% csrf_token %} not visible, why?

Question

Django

Through templatetags I connect the template with the form:

@register.inclusion_tag('loginsys/loginform.html')
def loginform():
    return {}

In the form itself, I display {% csrf_token %}:

<form method="post" action="{% url 'loginsys:login' %}">
{% csrf_token %}
    <input type="text" name="login[username]" id="username" placeholder="Логин" class="inputbox"/>
    <input type="password" name="login[password]" id="password" placeholder="Пароль" class="inputbox"/>
    <input class="button" value="" type="submit"/>
</form>

When submitting the form, I get:
Reason given for failure:
CSRF cookie not set.
Looking through the code, I don't see csrf_token in it. Tell me what is the problem here?

Answer 1

Did you forget to enable middleware? Did you pass RequestContext(request)?
And what for the form through a tag?
