Re: Good afternoon, I need help to generate a PDF of my models in DJANGO

"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.

    c.showPage()

    c.save()

    pdf=buffer.getvalue()

    

    c.showPage()

    c.save()

    pdf = buffer.getvalue()

    buffer.close()

    response.write(pdf)

    

    

    return response

    path(r'html',pruebapdf , name='PDF'),
