Models edit Tutorial

This section contains a step-by-step tutorial with examples for config the Models that make up our encuesta (survey).

We show you how to configure the file models.py to use PISCIS in your research. Allowing you to choose the images and the options that accompany them. Both make up the record of the answers that will be stored in the database.

Load Django librarys

from django.contrib.auth.models import User
from django.db import models

The class Images should not be edited unless you want to change the directory of images (edit “image”).

class Images(models.Model):
    picture = models.ImageField(upload_to="image")

The PISCIS user must edit CHOICE_TEXT to configure the options to be voted on. These follow the configuration (‘label save in .db’, ‘label show in web page’)

class Choice(models.Model):

    usuario = models.ForeignKey(User, on_delete=models.CASCADE, null=False)
    imagen = models.ForeignKey(
        Images, on_delete=models.CASCADE, blank=True, null=True)

    CHOICE_TEXT = (("A", "Alta"), ("B", "Baja"), ("C", "Media"))
    voto = models.CharField(max_length=20, choices=CHOICE_TEXT)
