Introduction to Django IntegerField

Web development, programming languages, Software testing & others

Syntax:

Name_of_field = models.IntegerField(**options)

Below is the syntax for Integer fields declaration. Here, the left-most item is the declared field. So, Here, the field’s name will be constituted. After that, reference the model’s library to extract the Integer field. So, the model’s library has an area called IntegerField class, and this IntegerField class is responsible for declaring the IntegerField. Next, declare the options associated with the IntegerField. So, the options like null, blank, or choices can be displayed in the options section. The null options mention whether the field can be null or not, next the blank field says what should be the value of the blank field value, and last, the choices mention the range of choices associated with this field.

How to Create a Django IntegerField?

The various steps to create Django IntegerField are as follows:

1. Changes in chúng tôi file

As the syntax section mentions, the integer field must be declared in the chúng tôi file. By observing the model, we can see that the integer field is declared as the “age” field.

models.py:

from chúng tôi import models from django.contrib.auth.models import User # Model variables # Create your models here. class Bride(models.Model): Example_name = models.CharField(max_length=200,null=True) Example_age = models.IntegerField(null=True) Example_thegai = models.CharField(max_length=200,null=True) Example_State = models.CharField(max_length=50,null=True) Example_District = models.CharField(max_length=50,null=True) Example_Address = models.TextField(null=True) Example_Phone = models.BigIntegerField(null=True) Example_profession = models.CharField(max_length=200,null=True) Example_salary = models.BigIntegerField(null=True) Example_Under_Graduation_Degree = models.CharField(max_length=200,null=True) Example_Under_Graduation_college = models.CharField(max_length=400,null=True) Example_Post_Graduation_Degree = models.CharField(max_length=200,null=True) Example_Post_Graduation_college = models.CharField(max_length=400,null=True) Example_Rasi = models.CharField(max_length=200,null=True) Example_Nakshatra = models.CharField(max_length=200,null=True) Image = models.ImageField(null=True,blank=True,upload_to="img/%y") def __str__(self): return self.name 2. Changes in chúng tôi file

Please ensure that you correctly set all the values and database connections in the chúng tôi file so that the project can execute flexibly. Make sure to appropriately declare the following middleware items in the chúng tôi file, as these middlewares are responsible for the application’s functioning during the processing of GET and PUT messages. Additionally, the templates used also need to fill so that the template processing happens in the background.

MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', ] ROOT_URLCONF = 'Matrimony.urls' 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', ], }, }, ] DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'db.sqlite3', } } STATIC_URL = '/static/' MEDIA_URL = '/images/' STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static'), ] print(STATICFILES_DIRS) STATIC_ROOT = os.path.join(BASE_DIR, 'static') MEDIA_ROOT = os.path.join(BASE_DIR, 'static/images') print(STATIC_ROOT) 3. Changes in chúng tôi file

The Media root and document root variables must be instantiated inside the chúng tôi file below. The changes for the chúng tôi file are mentioned below.

url.py:

from django.contrib import admin from chúng tôi import path from chúng tôi import url from matrimony_pages import views from chúng tôi import settings from django.conf.urls.static import static urlpatterns = [ url(r'^$',views.Welcome_page,name='Welcome_page'), url(r'Mainpage/',views.Main_page,name='Main_page'), url(r'form/',views.form_view,name='form_view'), url(r"signup/", views.Sign_up_request, name="register"), url(r"login/", views.login_request, name="login"), path(r'profile//',views.profile_page,name='profile'), url(r'logout/',views.logout_request,name='logout'), url(r'reg/',views.profile_reg_user,name='reg'), path(r'update//',views.form_update,name='update'), path('admin/', admin.site.urls), ]+ static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT) 4. Create a view for the form

The integer value, when submitted, has to be stored, and when retrieved, it has to be pulled from the database. This can be achieved using the object created for the model. The process of doing this is explained in the below-given chúng tôi section.

chúng tôi

@login_required def profile_page(request,pk): context2 = {} Key_details = Bride.objects.get(id=pk) Profile_name = Key_details.name Profile_Age = Key_details.age Profile_Thegai = Key_details.thegai Profile_state = Key_details.State Profile_district = Key_details.District Profile_Address = Key_details.Address Profile_Phone = Key_details.Phone Profile_Profession = Key_details.profession Profile_Salary = Key_details.salary Profile_UG = Key_details.Under_Graduation_Degree Profile_UGC = Key_details.Under_Graduation_college Profile_PG = Key_details.Post_Graduation_Degree Profile_PGC = Key_details.Post_Graduation_college Profile_UG = Key_details.Under_Graduation_Degree Profile_UGC = Key_details.Under_Graduation_college Profile_PG = Key_details.Post_Graduation_Degree Profile_PGC = Key_details.Post_Graduation_college Profile_Rasi = Key_details.Rasi Profile_Nakshatra = Key_details.Nakshatra Profile_Image = Key_details.Image context2['Age'] = Profile_Age context2['name'] = Profile_name context2['thegai'] = Profile_Thegai context2['State'] = Profile_state context2['district'] = Profile_district context2['Address'] = Profile_Address context2['Phone'] = Profile_Phone context2['profession'] = Profile_Profession context2['Under_Graduation_Degree'] = Profile_UG context2['Under_Graduation_college'] = Profile_UGC context2['Post_Graduation_Degree'] = Profile_PG context2['Post_Graduation_college'] = Profile_PGC context2['Rasi'] = Profile_Rasi context2['Nakshatra'] = Profile_Nakshatra context2['Image'] = Profile_Image print(Key_details.Creator) print(context2) return render(request,'Profilepage.html',context2) 5. Formulate an HTML file for displaying the form

You need to make corresponding changes to the HTML pages.

{% load static %} {% block content %} {% if Integer %} {% else %} {% endif%} {% endblock content %} function form1() { } function redirect1() { } function redirect2() { } function redirect3() { }

Output:

Conclusion

This article demonstrates how to handle the Integer field in a Django setup and render the variations to an HTML page with the integer value displayed at the desired position. The process also mentions the chúng tôi file changes and the other changes necessary to render these integer fields.
