CheckBox Tutorials in Django




The checkbox is used to check multiple options in the Django form.

We will use the Checkbox HTML element to design CheckBox.


Syntax of Checkbox for Django Form.


<input type="checkbox" name="chk[]"  value="content"    />Content
<input type="checkbox" name="chk[]"  value="content"   />Content



here chk[] is the list that contains multiple values.


We will use request.POST.getlist() to get the element of Checkbox and Listbox.



Step to implement Checkbox on Django Form using Single Method on Views.py:-

1) Create urls.py under app:-


from django.urls import path
from. import views


urlpatterns = [

    
    path('checkbox', views.checkbox, name='checkbox'),
 



 ]


2) Create templates/appname/checkbox.html



<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>

<form action="" method="post">
{% csrf_token %}

<input type="checkbox" name="chk[]" value="Java">Java
<br><br>
<input type="checkbox" name="chk[]" value=".NET">.NET
<br><br>
<input type="checkbox" name="chk[]" value="PHP">PHP
<br><br>
<input type="submit" name="btnsubmit" value="Click" />



</form>

{{key}}
</body>
</html>


3) write code on views.py:-

from django.shortcuts import render
from django.http import HttpResponse
def index(request):
if request.method=="POST":
p= request.POST["txtp"]
r= request.POST["txtr"]
t= request.POST["txtt"]
si = (float(p)*float(r)*float(t))/100
return render(request,"frontdesk/index.html",{"key":si})
return render(request,"frontdesk/index.html")


def checkbox(request):
if request.method=="POST":
s = request.POST.getlist("chk[]")
data=''
for s1 in s:
data = data +s1 +" "
return render(request,"frontdesk/checkbox.html",{'key':data})
return render(request,"frontdesk/checkbox.html")    





Create views.py using two different methods first for load and second for action

1)  Create view.py and implement two methods:-


from django.shortcuts import render
from django.http import HttpResponse
def index(request):
return render(request,"addapp/index.html")
def addlogic(request):
some_var = request.POST.getlist('checks[]')
data=''
if(len(some_var)>0):
  for data1 in some_var:
    data=data+data1 +" "
  return HttpResponse("checked data is "+data)
else:
  return HttpResponse("not checked")


2) create an HTML page for design using templates/appname/index.html

<form method="post" action="addlogic">
{% csrf_token %}
<input type="checkbox" name="checks[]" value="C" />C
<input type="checkbox" name="checks[]" value="CPP" />CPP
<input type="checkbox" name="checks[]" value="DS" />DS
<input type="checkbox" name="checks[]" value="E" />ETC
<input type="submit" name="btnsubmit">
</form>

  DSA in C# |  Data Structure and Algorithm using C#: Lecture 1: Introduction to Data Structures and Algorithms (1 Hour) 1.1 What are Data Structures? Data Structures are ways to store and organize data so it can be used efficiently. Think of data structures as containers that hold data in a specific format. Types of Data Structures: Primitive Data Structures : These are basic structures built into the language. Example: int , float , char , bool in C#. Example : csharp int age = 25;  // 'age' stores an integer value. bool isStudent = true;  // 'isStudent' stores a boolean value. Non-Primitive Data Structures : These are more complex and are built using primitive types. They are divided into: Linear : Arrays, Lists, Queues, Stacks (data is arranged in a sequence). Non-Linear : Trees, Graphs (data is connected in more complex ways). Example : // Array is a simple linear data structure int[] number...

Conditional Statement in Python

It is used to solve condition-based problems using if and else block-level statement. it provides a separate block for  if statement, else statement, and elif statement . elif statement is similar to elseif statement of C, C++ and Java languages. Type of Conditional Statement:- 1) Simple if:- We can write a single if statement also in python, it will execute when the condition is true. for example, One real-world problem is here?? we want to display the salary of employees when the salary will be above 10000 otherwise not displayed. Syntax:- if(condition):    statements The solution to the above problem sal = int(input("Enter salary")) if sal>10000:     print("Salary is "+str(sal)) Q)  WAP to increase the salary of employees from 500 if entered salary will be less than 10000 otherwise the same salaries will be displayed. Solution:- x = int(input("enter salary")) if x<10000:     x=x+500 print(x)   Q) WAP to display th...
