How to update a user password with Django RestFramework

Daniel Parkson Tano — Fri, 31 Mar 2023 07:26:37 +0000

You have probably been in situation where you coded a web app using a frontend framework like React Js or Angular and django for backend and django restframework to create API.
You need to allow a user (Admin or management) to update another users password directly from the frontend.
For example, let's assume you built a Human Resource management app for a company and the user with administrative priviledges can create an employee as well as update their credentials (password and username or email).

To do this after creating your user model in models.py file, now you will have to create Change password serializer in the serializers.py file

class ChangePasswordSerializer(serializers.ModelSerializer):
    password = serializers.CharField(write_only=True, required=True, validators=[validate_password])

    class Meta:
        model = User
        fields = ('password',)


    def update(self, instance, validated_data):

        instance.set_password(validated_data['password'])
        instance.save()

        return instance

The above block of code is a serializer that recieves the new password and updates the user account.
But no user credentials was passed for instance email or username. The next thing you have you do now is to create a view (ChangePasswordView) in your views.py files.

from rest_framework import generics 
class ChangePasswordView(generics.UpdateAPIView):

    queryset = User.objects.all()
    serializer_class = ChangePasswordSerializer

You are using a class base generic view so that the methods of the updateAPIView (Put and Patch) which will be inherited by your view class.

After creating your view class the last thing to do is to create url path to your view class in the urls.py file. As such

path('change_password/<int:pk>', ChangePasswordView.as_view(), name='auth_change_password')

The path takes a single argument which is the user_Id (or the primary key of your user model)

You can now make put request from your frontend code to the change_password/<int:pk> url.
Below is a code you can use with axios to make the http request

    const update_password = async (event) => {
        event.preventDefault();
        new_password != "" &&
            (await axios
                .put(API_URL + `account/change_password/${employee.user.id}`, {
                    password: new_password
                })
                .then(async (response) => {
                    alert("Password Successfully Changed")
                })
                .catch(async (err) => {
                    console.log(err);
                }))

Looking at the above code, let's take a walk through each statement:

new_password != "" &&
checks is the new password field is not null (empty). if the new password field is not null then the next part of the code is executed

await axios.put(API_URL + `account/change_password/${employee.user.id}`, {password: new_password })

We are using Async/await inoder to asynchronously execute the code. You have to pass in your change passowrd url path (API_URL + `account/change_password/) and the userID of the account you want to update thr password (for instance the userID here is stored in employee.user.id). You then make a put request using axios or Javascript Fetch.

This function will have to be called when a specific button is click (add OnClick={update_password} to your button).

Python swapcase without using Swapcase()

Daniel Parkson Tano — Mon, 26 Dec 2022 19:24:45 +0000

We can easily swap the cases of characters in string using the python inbuilt swapcase() function.
Casing swapping is simply changing upper case character to lower case character and lower case character to upper case character.
For example:
If we swap case the string "helloWorld" we will get "HELLOwORLD".

Example of using python swapcase()

Swap the cases in the string "Welcome to Tano Space".

string = "python IS A PROGRAMMING language"
new_string = swapcase(string)
print(new_string)
//it will return "PYTHON is a programming LANGUAGE"

It's simple right? Yes. But assuming you are in a technical interview for a python developer role, and the interviewer asked you to write a python thats swap the cases of characters in a string. You can't use the swapcase() function. How then will you be able to achieve such ?
The code below depict one of the ways to write the code.

Let me show you how

string = "python IS A PROGRAMMING language"
 new_string = []

for i in string:
    #check if the character is a upper case letter
    if i.isupper():
        #if the character is upper case the change it to lower 
        #case 
        i.lower()
        # add the converted character to the list
        new_string.append(i)
    else:
        i.upper()
        new_string.append(i)

#use the join() to combine the items of the list
print("".join(new_string)
