Landing on the New Job

Part of the Class-Based Views section of Coddy's Django journey. Lesson 11 of 18.

Post a job and Django saves it, then stops: No URL to redirect to. After saving, a CreateView redirects to its success_url. Without one, it asks the new row for its address through a model method, get_absolute_url().

The address of a row's page depends on the row, so the method belongs on the model. Build it with reverse(), which turns a route's name and arguments into a URL, as {% url %} does in a template:

class Recipe(models.Model):
    ...

    def get_absolute_url(self):
        return reverse("recipes:recipe", kwargs={"pk": self.pk})

Give the arguments by name with kwargs={...}, or in order with args=[...], and import reverse from django.urls. A template can link with {{ recipe.get_absolute_url }}, and an UpdateView lands there too.

Challenge

Medium

After posting, the browser should land on the new job's page:

In jobs/models.py, give Job a get_absolute_url() that returns the URL of its page, the route jobs:detail.
Leave JobCreateView as it is.

Press Run and post a job: you land on its page.

Try it yourself

from datetime import date

from django.conf import settings
from django.db import models
from django.utils.text import slugify


class Job(models.Model):
    title = models.CharField(max_length=200)
    company = models.CharField(max_length=200)
    city = models.CharField(max_length=100)
    salary = models.PositiveIntegerField(help_text="Yearly, in euros.")
    description = models.TextField(blank=True)
    posted = models.DateField(default=date.today)
    slug = models.SlugField(max_length=220, unique=True, blank=True)
    posted_by = models.ForeignKey(
        settings.AUTH_USER_MODEL,
        on_delete=models.SET_NULL,
        null=True,
        blank=True,
        related_name="jobs",
    )

    def __str__(self):
        return f"{self.title} at {self.company}"

    def save(self, *args, **kwargs):
        # A new job gets a slug from its title and company: "python-developer-acme".
        if not self.slug:
            base = slugify(f"{self.title} {self.company}") or "job"
            slug = base
            n = 2
            while Job.objects.filter(slug=slug).exists():
                slug = f"{base}-{n}"
                n += 1
            self.slug = slug
        super().save(*args, **kwargs)
