Generic Date Views - Python

 

Generic Date Views

Date-based generic views display drill-down pages for date-based data. They are

• ArchiveIndexView - A top-level index page showing the “latest” objects, by date.
• YearArchiveView - A yearly archive page showing all available months in a given year.
• MonthArchiveView - A monthly archive page showing all objects in a given month.
• WeekArchiveView - A weekly archive page showing all objects in a given week.
• DayArchiveView - A day archive page showing all objects in a given day.
• TodayArchiveView - A day archive page showing all objects for today.
• DateDetailView - A page representing an individual object.

More Editing Views - Python

 

More Editing Views

The form-based views can be extended for creating, updating, and deleting objects on the database.

This is done using,

• CreateView - View that displays a form for creating, saving an object and redisplaying the form with validation errors.
• UpdateView - View that displays a form generated from an object's model class for editing, saving an existing object and redisplaying the form with validation errors.
• DeleteView - View that displays a confirmation page and deletes an existing object based on a POST request.

Usage in views.py

class AuthorCreate(CreateView):
    model = Author
    fields = ['name']

class AuthorUpdate(UpdateView):
    model = Author
    fields = ['name']
    template_name_suffix = '_update_form'

class AuthorDelete(DeleteView):
    model = Author
    success_url = reverse_lazy('author-list')

Editing Views - FormView - Python

 

Editing Views - FormView

A FormView based view displays a form which

• on an error, redisplays the form with validation errors
• on success, redirects to a new URL. Consider a sample form created in forms.py that defines a CharField for capturing name

from django import forms

class ContactForm(forms.Form):
    name = forms.CharField()

    def send_email(self):
        # code to send email
        pass

A view can be defined using this form as shown. This determines if a form is valid and takes appropriate action (calling send_email in the below case).

class ContactView(FormView):
    template_name = 'contact.html'
    form_class = ContactForm
    success_url = '/thanks/'

    def form_valid(self, form):
        # Call this method when valid form data has been POSTed.
        form.send_email()
        return super().form_valid(form)

Display Views - ListView - Python

 

Display Views - ListView

The view is a display view representing a list of objects, identified by self.object_list.

For the same example as earlier, if you want to list all the articles available for a specific date, the ListView can be used instead of DetailView

from django.views.generic.list import ListView
...
class ArticleListView(ListView):
    model = Article

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['now'] = timezone.now()
        return context

The URL conf definition is the same as previous.

urlpatterns = [
    path('', ArticleListView.as_view(), name='article-list'),
]

The article headlines can be listed in an HTML file article_list.html by looping through the list of article objects as shown.

<ul>
{% for article in object_list %}
    <li>{{ article.pub_date|date }} - {{ article.headline }}</li>
{% empty %}
    <li>No articles yet.</li>
{% endfor %}
</ul>

Display Views - DetailView - Python

 

Display Views - DetailView

This display view represents the detail of a model object identified by self.object.

Consider the following view that gives the article information. The details are obtained by using the get_context_data method as shown

from django.views.generic.detail import DetailView
...
class ArticleDetailView(DetailView):
    model = Article

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['now'] = timezone.now()
        return context

The view is called in URLconf as below

urlpatterns = [
    path('<slug:slug>/', ArticleDetailView.as_view(), name='article-detail'),
]

The model object can be used as default data context and can be used in html template named as <model>_detail.html.

<p>{{ object.content }}</p>
<p>Reporter: {{ object.reporter }}</p>
<p>Published: {{ object.pub_date|date }}</p>

Usage of Class-Based Views - Python

 

Usage of Class-Based Views

Django's class-based views can be used:

• Directly used in URLconf, when the view is not modified.

urlpatterns = [
    path('readme/', TemplateView.as_view(template_name="readme.html")),
]

• As Generic views that
  • Inherits from a view and the corresponding attributes or methods can be modified.
  • Abstract common text phrases and patterns to write common views for reusability.
  • Can be used for display purposes or editing purposes.

In the next topics, you will look at some of the generic views in detail.

Class-Based Views - Python

 

Class-Based Views

The view functions, you have seen earlier, involve a lot of coding effort.

For responses that need a static page or a listing page, Django provides class-based views.

Using class-based views,

• Code organization is better.
• Specific HTTP methods like GET and POST can be addressed.
• Easy to build reusable components.
• No need to use render, redirect functions to send an HTTP response.

Let's consider a sample static content page written in static.html file.

Using a class-based view TemplateView, the template can be called as shown.

from django.views.generic import TemplateView

class StaticView(TemplateView):
   template_name = "static.html"

View Response Types - Python

 

View Response Types

Other than HTTPResponse we can use other inbuilt functions that can be used to respond to requests.

These are referred as Django shortcut functions. They are

• render() - Returns HttpResponse object by rendering the output on a template. Request and template_name are required arguments.
• redirect() - The view response is directly sent to a URL. This is the URL reversing concept and can be used either with a model or a view name or a direct URL as an argument.
• get_object_or_404 - Used when you need to get specific data from a model and return the model object. This raises Http404 exception when the object is not found.
• get_list_or_404 - Used when you need to get a list of model objects and returns Http404 exception if the list is empty.

Views in Python Defining a View

 

Defining a View

Views are defined in the file views.py within the app directory.

A sample definition would be

from django.http import HttpResponse

def greeting(request):
    html = "<html><body>Welcome to Django</body></html>"
    return HttpResponse(html)

• The class HttpResponse is imported from the django.http module.
• greeting is the view function that takes an HttpRequest object as its first parameter named request.
• The generated response in an HTML format is returned as an HttpResponse object by the view.
