包含块未显示在 Django 模板中

Question

Well, i've designed something but i am not sure, how to implement it.

models.py

class Notificaciones(models.Model):
 IDcliente = models.ManyToManyField(User)
 Tipo_de_notificaciones = ( (1,'Ofertas'),(2,'Error'),(3,'Informacion'))
 Tipo = models.IntegerField('Tipo de notificacion',choices=Tipo_de_notificaciones, default=3,)
 Nombre_not = models.CharField("Nombre de la notifiacion",max_length=50)
 Descripcion_not = HTMLField("Descripcion de la notificacion")
 Imagen_not = models.ImageField("Imagen de la notificacion",upload_to="notificaciones")
 Fecha_Caducidad_notificacion = models.DateTimeField("Fecha de caducidad de la notificacion",auto_now_add=False)
 class Meta:
     verbose_name = 'Notificacion'
     verbose_name_plural = 'Notificaciones'
 def __str__(self):
     return self.Nombre_not

views.py

def notifi(request):
 notifi = Notificaciones.objects.all()
 return render_to_response('app/notificaciones.html',{ 'notifi' : notifi })

Now I want to show the notification in a header in a lightbox, then in my layout.html, where header, footer and etc. are called. But when I call notification, it does not appear.

<div id="notifiaciones" class="notificaciones notificacionesTrans" tabindex="-1" role="dialog" aria-hidden="true" >
    {% include 'app/notificaciones.html' %}
</div>

Can someone explain if I can call the notification from views or should it be done somehow else?

URL.PY

url(r'^tinymce/', include('tinymce.urls')),
url('', include('django.contrib.auth.urls', namespace='auth')),

Notificación.html

<ul>
{% for  notifi in notifi %}
    <li>{{ notifi.Tipo }}
        {{ notifi.Nombre_not }}
        <img src="{{ notifi.Imagen_not }}" alt="{{ notifi.Nombre_not }}"/>
        {{ notifi.Fecha_Caducidad_notificacion }}
    </li>
{% endfor %}
</ul>

Login Form Inside layout.html

Answer 1

The problem is, django.contrib.auth.views.login is what renders the index.html page (as you can see from here):

url(r'^$', 'django.contrib.auth.views.login',{'template_name':'app/index.html'}, name='Vulpini.co'),

The index.html page extends layout.html and layout.html includes notificaciones.html. At no point do these templates get passed the 'notifi' variable (that is why nothing shows up - because django.contrib.auth.views.login does not pass any 'notifi' variable to your template(s)). In order to accomplish what you want to do, change the URL to this:

url(r'^$', 'app.views.index', name='Vulpini.co'),

and then in your views.py, add this view:

def index(request):
 notifi = Notificaciones.objects.all()
 return render_to_response('app/index.html',{ 'notifi' : notifi })

Once this is done, then index.html (which extends layout.html which calls notificaciones.html) will have access to the 'notifi' variable. Then in your index.html template, you can make a form post to "/login" which uses django.contrib.auth.view.login, like this:

url(r'^login$', 'django.contrib.auth.views.login', name='Vulpini.co'),

and in your settings.py, set this:

LOGIN_REDIRECT_URL = '/'

to redirect back to the index.html page after logging in.

Edit: Since this is the checked off answer, I'd like to point out that another option (as chem1st said in his answer), would be to have a look at context processors here: https://docs.djangoproject.com/en/1.7/ref/templates/api/#writing-your-own-context-processors

View chem1st's answer for more information.

Answer 2

Include and extends blocks do nothing with passing the data from view to a template. If you want to be able to get smth from a view, pass it explicitly.

You should also have look at context processors , since they will allow you to globally achive the data you want.
