Suggested November 2023 Using Templates To Render Django Views

Introduction to Django Templates

To understand and operate the process of Django applications, these templates play a major role; all static items in a web page designed with Django hold the templates for constructing the static entities. In other words, it could be described that the templates are responsible for building the skeleton of a webpage. These templates make a Django setup an MVT-oriented architecture. M stands for the models involved, V stands for the views designed, and T refers to the templates. On Standard ways, the templates used in a Python setup are rendered using a Django view.

Using Templates to Render Django Views 1. Create a template folder

All template-related HTML code could be placed into this folder. The template folder has to be created under the primary project folder.

2. Tag the template folder in chúng tôi file

The chúng tôi file is used for tagging these templates to their associated views. When the tagging process is accomplished, all the HTML contents placed inside the folder fall under this template section.

Code:

import os # Build paths inside the project like this: os.path.join(BASE_DIR,...) BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) Template_DIR = os.path.join(BASE_DIR,'Templates') TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [Template_DIR,], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', , }, }, ]Template_DIR = os.path.join(BASE_DIR,'Templates')

The Python path in the BACKEtemplate’sused to implement the Django template’s API backend. Some backends built-in Django are django.template.backends.django.DjangoTemplates and django.template.backends.jinja2.Jinja2.

The directory in which the template engine needs to locate the template-related search files is placed in the DIRS directory.

Whereas the APP_DIRS helps mention the location at which the engine has to verify the templates within the installed applications. Each defined backend provides a conventional name for every subdirectory inside the applications.

3. Place the HTML file inside the templates folder

Code:

Syntax:

render(request,template_name,context=None,content_type=None,status=None,using=None)

Arguments Description

request This is used to generate a response. This is a mandatory argument.

template name Name of the template used for this view. This is a mandatory argument.

context A context is a variable name and variable value mapping maintained as a dictionary. By default, this is an empty dictionary. So if the key is passed, the corresponding value from the dictionary can be retrieved and rendered. This is an optional argument. If nothing is provided for the context, then render an empty context.

content_type MIME(Multipurpose Internet Mail Extensions) to be used. The default value is ‘text/html’. This is an optional argument.

status The response code to be used. The default response code is 200.

using This argument represents the name of the template engine used for loading the template. This is an optional argument.

Example: Code:

from django.shortcuts import render from chúng tôi import HttpResponse def index(request_iter): return render(request_iter,'design.html') 4. Tag the view in chúng tôi file

This is the process of creating a url for the view. The url mentioned here will be used to reach the web page mentioned.

Import the library from chúng tôi import url.

url(url_path,view_to_be_tagged,name_for_this_view)

Example:

Code:

from django.contrib import admin from chúng tôi import url from Django_app1 import views urlpatterns = [ url(r'^$',views.index,name='index'), url(r'admin/',admin.site.urls),] 5. Reload the server using the python chúng tôi runserver command and verify webpage

Code:

Watching for file changes with StatReloader Performing system checks... System check identified no issues (0 silenced). June 10, 2023 - 11:23:00 Django version 3.0.7, using settings 'educba.settings' Quit the server with CTRL-BREAK.

Output:

Django View Rendered from Template Tag

Given below is the Django view rendered from the template tag:

1. The template tags inject dynamically generated content into the Django views. This is among the key functionalities of template tags. They could flexibly inject dynamic content into the file.

The template tag filters could use the below-listed options:

All Options in the Template Filters

add addslashes capfirst

center cut date

default dictsort divisibleby

escape filesizeformat first

join last length

linenumbers lower make_list

random slice slugify

time timesince title

unordered_list upper wordcount

Add a template tag in the HTML file.

Code:

{% if Entity_type == ‘tutorial’ %} {{ Entity_name }} {% else %} {{ Error_Message }} {% endif %}

Example:

from django.shortcuts import render from chúng tôi import HttpResponse def index(request_iter): dict_Var = { "Entity_name": "Educba", "Entity_type": "tutorial", "Entity_students_count": 345, "Error_Message": "No Valid Entity found" } return render(request_iter,'design.html',context=dict_Var)

3. Reload the server using the python chúng tôi runserver command and verify the webpage.

Output:

Conclusion

The use of templates is one among the biggest capabilities of Django in the web development framework. These templates allow the Django setup to flexibly transfer dynamic content between the front end and the middle stream.
