How to create Template in Django?
1) It is possible using Django to separate the coding of HTML and Python. Until now, you must be clear with the fact that Python goes in Views. On the other hand, HTML goes in templates. Now, to link these two separately coded modules, there is a need to rely on the render function. Here, you will also be using Django Template Language.
2) For loading the template on browser you have to create one function in app/views.py file.
def function_name(request):
return render(request,"app/index.html")
return render(request,"app/index.html")
#index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=h1, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<h1>Hello hrsikh</h1>
</body>
</html>
#views.py
from django.shortcuts import render
# Create your views here.
def Index(request):
return render(request,"index.html")
#urls.py
from django.urls import path,include
from .import views
urlpatterns = [
path("",views.Index,name="index"),
]
HTML Form
1) An HTML form is used to collect user input. The user input is most often sent to a server for processing.
2) The HTML <form> element is used to create an HTML form for user input.
<form>
form element
</form>
#forms.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<center>
<h1>HRSIKH</h1>
<form action="" method="post">
<table>
<tr>
<td>Firstname</td>
<td><input type="text" name="" id=""></td>
</tr>
<tr>
<td>Lastname</td>
<td><input type="text" name="" id=""></td>
</tr>
<tr>
<td>Email</td>
<td><input type="text" name="" id=""></td>
</tr>
<tr>
<td>content</td>
<td><input type="text" name="" id=""></td>
</tr>
<tr>
<td><input type="submit" value="Submit"></td>
</tr>
</table>
</form>
</center>
</body>
</html>
#view.py
from django.shortcuts import render
# Create your views here.
def form(request):
return render(request,"forms.html")
#urls.py
from django.urls import path,include
from .import views
urlpatterns = [
path("",views.form,name="form"),
]
Output:
