This can be a problem when you have two apps in a project with a template with the same name. Say you have created an index. Your folder structure will look like this:. When you tell Django to load the template index. We solve this problem by namespacing our templates. Namespacing templates is simple—we add a folder named after the app to our templates folder. This is what the above example looks like after namespacing the templates:. As with most things in Django, namespacing templates is a convention, not a hard and fast rule.
But, if you want maximum portability for your apps and to avoid some headaches later on, it is a convention that you would do well to follow. Before moving on, add the new folder to your events app. All modern websites have a site template that creates a common look and branding for every page on the website. The most common place for storing site template files in Django is in the website app that Django created automatically for you when you ran startproject.
Line 4 looks complicated, but is easy to understand— os. Note that Django will search your DIRS list in the order listed, so keep in mind my previous warnings about templates with the same name when linking to external resources. We will name this file base. This is plain HTML except for lines 9 and If you remember from the view we created in the last chapter, these are the same variable names we gave the event title and calendar respectively.
This is done in your views. Modify the index view as follows changes in bold :. For our new view, we have replaced the call to HttpResponse with a call to render. I have commented out the original HttpResponse line 15 so you can more easily see the changes. If you remember from Chapter 5, when Django receives a request from a browser, it finds the right view, and the view returns a response to the browser. However, when we wish to use a template, Django first must load the template, create a context—which is a dictionary of variables and associated data passed back to the browser—and return an HttpResponse.
Using render is so common that Django added it to the views. When you supply the original request, the template and a context to render , it returns the formatted response without you having to code the intermediate steps.
In our modified views. Once you have modified your views. If you look at the page source, you can see why:. This is because, by default, Django autoescapes all code before sending it to the browser.
This is a built-in security feature designed to prevent a hacker inserting malicious code into your site code. As this is a common task, the Django developers created the autoescape tag to make life easy for you. Make the following changes to your base. Figure The site template rendered with autoescape off for the calendar code. A site template needs to be independent of all the other apps in your Django project.
It has been steadily increasing in popularity since its release and still continues to be a favorite among Python developers. However powerful it is, Django can not suit every web project. It can get slow, restrictive, and monolithic for small-scale projects. It becomes necessary to look at alternative frameworks in such cases. Thus, we bring to you the best web frameworks you can use as Django alternatives for your next web project. While some alternatives are based on Python like Django, we also list some popular web frameworks for other programming languages.
Django is a high-level, open-source web framework that encourages rapid development. Used in web development of Python programming language, it ensures the implementation of a clean pragmatic application design. Django comes with most of the common libraries and tools required for web development and is therefore called a batteries-included framework.
It requires no additional installation. The Django web framework offers a complete suite of features such as data binding, boilerplate coding, flexibility, reusability, high productivity, and extensibility.
Companies like Bitbucket , Pinterest , Instagram , and Onion use Django in their tech stack to produce engaging user experience. Another point of importance is that Django includes all the functionalities to secure websites and helps developers avoid web security mistakes.
These are some of the most important benefits of Django. Other advantages of the web framework are-. Use Django to take your web app idea to the next level with advanced AI features.

Some cons of using Django as a framework are —. Python in itself is a very slow programming language. It is very important to design the application architecture correctly or developers will face some serious issues with speed.
It is comparatively slower than other backend frameworks. Everything has to be explicitly defined by developers in Django. There is no standardization or a default configuration available. This lack of convention in Django results in a lot of extra time spent in developing the source code. Besides, developers need to fully understand each concept before implementing it correctly. Everything in Django requires using the ORM be it frontend or backend development.
Although the ORM is very powerful and useful in situations handling large databases, it can create problems. You have to manually change the ORM when you are performing simple tasks such as designing a UI element. Certain internal Django modules, such as the powerful admin panel, are sometimes tough to work with.
The admin panel is automatically generated every time by the framework. This can be super helpful, but also extremely cumbersome for small static websites. You need to work for hours on reconfiguring the modules if you want to generate dynamic statistics and links. WebSockets is a web service that allows you to update events or content in real-time.
But Django does not support web sockets yet. In addition, to cut down on the repetitive nature of loading and rendering templates, Django provides a shortcut function which automates the process. It takes the following arguments. Template engines are available in django. DjangoTemplates' to configure a Django template engine. This generic name was kept for backwards-compatibility. These callables take a request object as their argument and return a dict of items to be merged into the context.
See RequestContext for more information. If it is True , the fancy error page will display a detailed report for any exception raised during template rendering. This report contains the relevant snippet of the template with the appropriate line highlighted. Each Loader class knows how to import templates from a particular source.
Optionally, a tuple can be used instead of a string. The first item in the tuple should be the Loader class name, and subsequent items are passed to the Loader during initialization. See Loader types for details. See How invalid variables are handled for details.
It defaults to 'utf-8'. This can be used to add new libraries or provide alternate labels for existing ones. For example:. Requires Jinja2 to be installed:. Jinja2' to configure a Jinja2 engine. It defaults to 'jinja2. Django invokes that callable and passes other options as keyword arguments. Environment as described below. You can then call that function in the template:. Some Django templates context processors return a fixed value. Unless all of these conditions are met, passing a function to the template is more in line with the design of Jinja2.
The default configuration is purposefully kept to a minimum. Thanks for your time. You can find the finished app in github. See you next time with another part of the series. Stats Basic Django-registration-and-login-system repo stats. Mentions 1. Stars 9. Activity 5.
