CreateView

Part of the Class-Based Views section of Coddy's Django journey. Lesson 10 of 18.

The menu has a Post a job link with no page behind it. A page that adds a row is the same code every time: show an empty form, check what was posted, save it, redirect. CreateView is that code, with a ModelForm it builds for you:

from django.views.generic import CreateView


class RecipeCreateView(CreateView):
    model = Recipe
    fields = ["title", "cuisine", "minutes"]

fields lists the form's fields, like a ModelForm's Meta. The template defaults to recipes/recipe_form.html, with the form as form. Invalid data shows the form again with its errors, and nothing is saved.

Put the route "recipes/new/" above "recipes/<slug:slug>/". Django uses the first route that matches. new is a valid slug, so a slug route above this one catches /recipes/new/ and responds with 404.

Challenge

Medium

Make the page behind Post a job, with the ready template jobs/job_form.html.

In jobs/views.py, add JobCreateView, a CreateView of Job with the fields title, company, city, salary and description.
In jobs/urls.py, add the route "jobs/new/" named create.

Post a job: it is saved, then Django stops with No URL to redirect to, which the next lesson fixes.

Try it yourself

from django.views.generic import DetailView, ListView, TemplateView

from .models import Job


class HomeView(TemplateView):
    template_name = "jobs/home.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context["count"] = Job.objects.count()
        context["latest"] = Job.objects.order_by("-posted").first()
        return context


class AboutView(TemplateView):
    template_name = "jobs/about.html"


class JobListView(ListView):
    model = Job
    context_object_name = "jobs"
    ordering = ["-posted"]
    paginate_by = 5

    def get_queryset(self):
        jobs = super().get_queryset()
        city = self.request.GET.get("city")
        if city:
            jobs = jobs.filter(city=city)
        return jobs


class JobDetailView(DetailView):
    model = Job
