Using Django. I have info on amount of page in database this amount is entered by each user and stored in bd. my concern is: How can I page with the amount I have stored in bd, for example, change 25 by the number I have in my database that I have in database?
class Datos(ListView):
model = Datos
template_name = 'Datos.html'
paginate_by = 25In my model:
class ProfileUser(models.Model):
pagination = models.IntegerField(default=50)Thanks
One way to modify it is to modify the variable paginate_by within the function get_context_data() but the most recommendable thing is to overwrite the function get_queryset() in this way:
from django.core.paginator import Paginator
def get_queryset(self,npagina=1):
consulta = Datos.objects.all()
paginacion = Paginator(consulta,'cantidad objetos')
if len(paginacion.page(1)) == 0:
return None
else:
return paginacion.page(npagina)
You must modify your get_context_data to obtain the result and pass it to your template adding this: context ['data'] = self.get_queryset (npagina = self.request.GET.get ('page'))
And finally add this your tamplate:
{% if is_paginated %}
<ul class="pagination">
{% if datos.has_previous %}
<li>
<span><a href="?page={{ page_obj.previous_page_number }}{% if parametros.urlencode %}&{{ parametros.urlencode }}{% endif %}">Anterior</a></span>
</li>
{% endif %}
<li class="">
<span>Página {{ page_obj.number }} de {{ page_obj.paginator.num_pages }}.</span>
</li>
{% if datos.has_next %}
<li>
<span><a href="?page={{ page_obj.next_page_number }}{% if parametros.urlencode %}&{{ parametros.urlencode }}{% endif %}">Siguiente</a></span>
</li>
{% endif %}
</ul>
{% endif %}
You can modify the function of get_queryset to your liking, it's just an example so you can modify it the way you want
Good morning I hope you are well, I wanted to ask for help since I am in the same situation. In context ['data'], 'data' what would it be? I'm just starting in Django so I do not have much experience, thank you very much
