[mezzanine-users] Re: Can't get mezzanine to render template with real time database entries
Sorry for not giving much detail,
The object is being passed to direct_to_template view method:
extra_context = {"menssagens": Menssagem.objects.filter(publicado=True)}
url("^$", direct_to_template, {"template": "index.html", "extra_context":
extra_context}, name="home"),
I have also tried creating a custom view.
And this is my models.py
class Menssagem(models.Model):
menssagem = models.TextField()
publicado = models.BooleanField(default=False)
class Meta:
verbose_name = "Menssagem"
verbose_name_plural = "Menssagens"

[mezzanine-users] Re: Can't get mezzanine to render template with real time database entries
I figured it out,
The problem was that the object was being requested from database on script
import and not on the function call. I looked everywhere for the answer but
it was right in front of me. Breaks are good for the mind.
Thanks and sorry for the dumb question

Eduardo Rivas, just saw your answer, thanks for the help. This happens
sometimes to me, when I focus too much on the problem i can't see the anwer.
I don't know much about page processors, I will study this!
The solution i gave was a simple view:
def index(request):
menssagens = Menssagem.objects.filter(publicado=True)
return render(request, "index.html", {'menssagens': menssagens})

Re: [mezzanine-users] Re: Can't get mezzanine to render template with real time database entries
Alright, so urls.py is loaded when the server is started. It means that the extra_context variable stores the Menssagem objects that are published at that time. The value is not updated on every request, which means that the published objects are never re-fetched. This is why you only get the new objects after a server restart. My advice is that you create a very thin view, either function or class-based, to make sure your logic is executed on every request, not only on server load. Another option is to create a page processor for "/", injecting the context you want. http://mezzanine.jupo.org/docs/content-architecture.html#page-processors.
