Inflow and Outflow record of money can be easily kept with the help of expense tracker. It helps to manage finances. In this project, we will develop an expense tracker that will track our expenses. Let\u2019s start developing the project.<\/p>\n

Python Expense Tracker Project<\/h3>\n

In this python django project, we will create an expense tracker that will take details of our expenses. While filling the signup form a person will also need to fill in the details about the income and the amount he\/she wants to save. Some people earn on a daily basis, so their income can also be added on a regular basis. Details of expenses will be shown in the form of a pie chart on a weekly, monthly, and yearly basis. Installation of django is a must to start with the Expense Tracker project.<\/p>\n

Project Prerequisites<\/h3>\n

Sound knowledge of django framework, html, css, javascript and python is required before starting this Expense Tracker project of Python.<\/p>\n

Create a template and static folder to store your files. Template folder will contain all the html files. Static folder will contain all the css files ,images and javascript files.<\/p>\n
3. Models.py<\/h4>\n
Database connectivity is done with the help of models.py. Create the following models in models.py file in the app of your project.<\/p>\n
from django.db import models\r\nfrom django.utils.timezone import now\r\nfrom django.contrib.auth.models import User\r\nfrom django.conf import settings\r\nfrom django.db.models.signals import post_save\r\nfrom django.dispatch import receiver\r\nfrom django.db.models import Sum\r\n#Create your models here.\r\nSELECT_CATEGORY_CHOICES = [\r\n    (\"Food\",\"Food\"),\r\n    (\"Travel\",\"Travel\"),\r\n    (\"Shopping\",\"Shopping\"),\r\n    (\"Necessities\",\"Necessities\"),\r\n    (\"Entertainment\",\"Entertainment\"),\r\n    (\"Other\",\"Other\")\r\n ]\r\nADD_EXPENSE_CHOICES = [\r\n     (\"Expense\",\"Expense\"),\r\n     (\"Income\",\"Income\")\r\n ]\r\nPROFESSION_CHOICES =[\r\n    (\"Employee\",\"Employee\"),\r\n    (\"Business\",\"Business\"),\r\n    (\"Student\",\"Student\"),\r\n    (\"Other\",\"Other\")\r\n]\r\nclass Addmoney_info(models.Model):\r\n    user = models.ForeignKey(User,default = 1, on_delete=models.CASCADE)\r\n    add_money = models.CharField(max_length = 10 , choices = ADD_EXPENSE_CHOICES )\r\n    quantity = models.BigIntegerField()\r\n    Date = models.DateField(default = now)\r\n    Category = models.CharField( max_length = 20, choices = SELECT_CATEGORY_CHOICES , default ='Food')\r\n    class Meta:\r\n        db_table:'addmoney'\r\n        \r\nclass UserProfile(models.Model):\r\n    user = models.OneToOneField(User,on_delete=models.CASCADE)\r\n    profession = models.CharField(max_length = 10, choices=PROFESSION_CHOICES)\r\n    Savings = models.IntegerField( null=True, blank=True)\r\n    income = models.BigIntegerField(null=True, blank=True)\r\n    image = models.ImageField(upload_to='profile_image',blank=True)\r\n    def __str__(self):\r\n       return self.user.username\r\n<\/pre>\n
Code Explanation:<\/strong><\/p>\n
SELECT_CATEGORY_CHOICES , EXPENSE_CHOICES , PROFESSION_CHOICES contain the list of options that will be given while filling the expense form.<\/p>\n
a. Foreign key: It establishes many to one relationship.<\/p>\n
b. Charfield():It stores small and large size strings in the database.<\/p>\n
c. BigIntegerField():It can store numbers from -9223372036854775808 to 9223372036854775807 in the database.<\/p>\n
d. Datefield(): It accepts date as input.<\/p>\n
e. Integerfield():It stores integer numbers in a database.<\/p>\n
f. Imagefield():It stores images in the database.<\/p>\n
4. Admin.py<\/h4>\n
It will help register the tables in the database.<\/p>\n
# Register your models here.\r\nfrom .models import Addmoney_info\r\nFrom django.contrib import admin\r\nclass Addmoney_infoAdmin(admin.ModelAdmin):\r\n    list_display=(\"user\",\"quantity\",\"Date\",\"Category\",\"add_money\")\r\nadmin.site.register(Addmoney_info,Addmoney_infoAdmin)\r\nfrom django.contrib.sessions.models import Session\r\nadmin.site.register(Session)\r\nfrom .models import UserProfile\r\nadmin.site.register(UserProfile)\r\n<\/pre>\n
Code Explanation:<\/strong>
\nAddmoney_info, UserProfile are the names of the models that we want to register in the database. list_display contains the name of the columns that will be displayed in the database.<\/p>\n
To store these models in the database, run the following command:<\/p>\n
python manage.py makemigrations\r\n     python manage.py migrate\r\n<\/pre>\n
For accessing the database, create the superuser. To create a superuser run the following command on your terminal window.<\/p>\n
python manage.py createsuperuser<\/p>\n
5. Urls.py<\/h4>\n

a. Importing modules<\/strong><\/p>\n
from django.shortcuts import render,HttpResponse,redirect\r\nfrom django.contrib import messages\r\nfrom django.contrib.auth import authenticate ,logout\r\nfrom django.contrib.auth import login as dj_login\r\nfrom django.contrib.auth.models import User\r\nfrom .models import Addmoney_info,UserProfile\r\nfrom django.contrib.sessions.models import Session\r\nfrom django.core.paginator import Paginator, EmptyPage , PageNotAnInteger\r\nfrom django.db.models import Sum\r\nfrom django.http import JsonResponse\r\nimport datetime\r\nfrom django.utils import timezone\r\n<\/pre>\n
Code Explanation:<\/strong><\/p>\n
a. Render: It returns the Httpresponse object and combines the template with the dictionary that is mentioned in it.
\nb. HttpResponse: It displays a text response to the user.
\nc. Redirect: It redirects the user to the specified url.
\nd. Messages: It helps to store and display messages to the user on the screen.
\ne. Authenticate: It verifies the user.
\nf. User: This model handles authentication as well as authorization.
\ng. Session: It helps the user to access only their data. Without sessions, every user\u2019s data will be displayed to the user.
\nh. Paginator: It is used to manage paginated data.
\ni. datetime:It is used to get the current date and time.<\/p>\n
b. Login and Index function<\/strong><\/p>\n
def home(request):\r\n    if request.session.has_key('is_logged'):\r\n        return redirect('\/index')\r\n    return render(request,'home\/login.html')\r\n   # return HttpResponse('This is home')\r\ndef index(request):\r\n    if request.session.has_key('is_logged'):\r\n        user_id = request.session[\"user_id\"]\r\n        user = User.objects.get(id=user_id)\r\n        addmoney_info = Addmoney_info.objects.filter(user=user).order_by('-Date')\r\n        paginator = Paginator(addmoney_info , 4)\r\n        page_number = request.GET.get('page')\r\n        page_obj = Paginator.get_page(paginator,page_number)\r\n        context = {\r\n            # 'add_info' : addmoney_info,\r\n           'page_obj' : page_obj\r\n        }\r\n    #if request.session.has_key('is_logged'):\r\n        return render(request,'home\/index.html',context)\r\n    return redirect('home')\r\n<\/pre>\n
Code Explanation:<\/strong><\/p>\n
home() is a function that allows the user to access the dashboard once the user is logged in. index() function contains the backend of the dashboard page.<\/p>\n
a. filter(): Queryset is filtered by filter().<\/p>\n
b. get(): Single unique object can be obtained with get().<\/p>\n
c. order_by(): It orders the queryset.<\/p>\n
c. Other Functions<\/strong><\/p>\n
def addmoney(request):\r\n    return render(request,'home\/addmoney.html')\r\n \r\ndef profile(request):\r\n    if request.session.has_key('is_logged'):\r\n        return render(request,'home\/profile.html')\r\n    return redirect('\/home')\r\n \r\ndef profile_edit(request,id):\r\n    if request.session.has_key('is_logged'):\r\n        add = User.objects.get(id=id)\r\n \r\n        return render(request,'home\/profile_edit.html',{'add':add})\r\n    return redirect(\"\/home\")\r\n<\/pre>\n
Code Explanation:<\/strong><\/p>\n
The first function redirects the user to the page where we can enter our expenses and income. profile() function redirects the user to the profile page where information of the user is displayed. profile_edit() redirects to the page where information of the user can be edited. These pages can only be accessed if the user is logged in.<\/p>\n
d. Updating Profile<\/strong><\/p>\n
def profile_update(request,id):\r\n    if request.session.has_key('is_logged'):\r\n        if request.method == \"POST\":\r\n            user = User.objects.get(id=id)\r\n            user.first_name = request.POST[\"fname\"]\r\n            user.last_name = request.POST[\"lname\"]\r\n            user.email = request.POST[\"email\"]\r\n            user.userprofile.Savings = request.POST[\"Savings\"]\r\n            user.userprofile.income = request.POST[\"income\"]\r\n            user.userprofile.profession = request.POST[\"profession\"]\r\n            user.userprofile.save()\r\n            user.save()\r\n            return redirect(\"\/profile\")\r\n    return redirect(\"\/home\")   \r\n<\/pre>\n
Code Explanation:<\/strong><\/p>\n
profile_update() function performs the backend of the edit profile form. User.objects.get() gets all the information of the user then all the updated information is saved again. This function is performed by save().<\/p>\n

Code Explanation:<\/strong><\/p>\n
expense_month() function gets the data of the expenses of the current month. get_category() function gets the category (expense\/income) from the database. get_expense_category_amount() fetches the amount from the database of the category(expense). stats() function calculates the overall expenses and savings made by the user in a month. expense_week() and info_year() performs the same function as expense_month() but on a weekly basis. weekly() gets the amount saved in a month and also the overall expenses of a user.<\/p>\n
