"pruebapdf() missing 1 required positional argument: 'DesdeJango'"
Your view have an additional parameter, which is not used by views; views
always receive the "request" and then the list of parameters in your URL
definition (which does not have any parameters). So you need to remove it
from the function and actually import the class from your models.
