Introduction to Django DateTimeField
As per Django is concerned there are several field types through which the date and time values can be injected for storage on the models. The difference between these fields arises on the format of the data being stored. There are options to store only date value, even time value alone can be capture. As per datetime field both date and time values will be captured. The user will be expected to place both the date and time value at the time of injecting the values for the storage. The stored value can again be retrieved back and displayed on to the console.
Ex: 10-07-2019 00:20
Syntax:
Name_of_field = models.DateTimeField(**options)
The above syntax corresponds to the Django DateTimeField example. The first column mentioned here is the name of the field involved. The first column will form the field name, next to it comes the models.DateTimeField extension. This extension means to export the DateTime field method from the model’s section. So the model’s section will now import the DateTimeField method to generate the expected field. Then the arguments of the DateTimeField() method has to be declared. The usual values here are the null argument which mentions what needs to be the value for the records in which the valid date-time is not in place. The next argument will be the blank argument.
Create a Django DateTimeField
1. Changes in Models.py file:
As mentioned in the syntax section the Date Time field needs to be declared in the models.py file. We can notice that the Date Time field is declared as the age field in the model.
(models.py)
from django.db import models
from django.contrib.auth.models import User
# Model variables
# Create your models here.
class Bride(models.Model):
DATE_TIME_name = models.CharField(max_length=200,null=True)
DATE_TIME_age = models.Date Time field_Example_Field(null=True)
DATE_TIME_DOB = models. DateTimeField (null=True)
DATE_TIME_thegai = models.CharField(max_length=200,null=True)
DATE_TIME_State = models.CharField(max_length=50,null=True)
DATE_TIME_District = models.CharField(max_length=50,null=True)
DATE_TIME_Address = models.TextField(null=True)
DATE_TIME_Phone = models.BigInteger(null=True)
DATE_TIME_profession = models.CharField(max_length=200,null=True)
DATE_TIME_salary = models.BigInteger(null=True)
DATE_TIME_Under_Graduation_Degree = models.CharField(max_length=200,null=True)
DATE_TIME_Under_Graduation_college = models.CharField(max_length=400,null=True)
DATE_TIME_Post_Graduation_Degree = models.CharField(max_length=200,null=True)
DATE_TIME_Post_Graduation_college = models.CharField(max_length=400,null=True)
DATE_TIME_Rasi = models.CharField(max_length=200,null=True)
DATE_TIME_Nakshatra = models.CharField(max_length=200,null=True)
def __str__(self):
return self.name
2. Changes in Settings.py file:
Ensure all of the values and the database connects are set nicely withinside the settings.py document in order that the venture may be kicked for execution flexibly. The middleware objects stated underneath needs to be declared nicely withinside the settings.py document, due to the fact those center wares are liable for functioning of the software even as processing GET and PUT messages. Additionally, the templates used has additionally want to crammed in order that the template processing occurs withinside the background.
(Settings.py):
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
] ROOT_URLCONF = 'Matrimony.urls'
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [Template_DIR,],
'APP_DIRS': True,
'OPTIONS': {
'render_dict_processors': [
'django.template.render_dict_processors.debug',
'django.template.render_dict_processors.request',
'django.contrib.auth.render_dict_processors.auth',
'django.contrib.messages.render_dict_processors.messages',
],
},
},
]
3. Changes in url.py file:
The Media root and document root variable need to be instantiated inside the url.py file as like below. The changes for the url.py file are mentioned below.
url.py:
from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from matrimony_pages import views
from django.conf 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/<str:pk>/',views.DATE_TIME_page,name='profile'),
url(r'logout/',views.logout_request,name='logout'),
url(r'reg/',views.DATE_TIME_reg_user,name='reg'),
path(r'update/<str:pk>/',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 Date Time field value when submitted has to be stored and when retrieved it has to be pulled from the database. This can be achieved by means of the object created for the model. The process of doing this is explained in the below given views.py section.
Ex: views.py
@login_required
def DATE_TIME_page(request,pk):
render_dict2 = {}
Key_details = Bride.objects.get(id=pk)
DATE_TIME_name = Key_details.name
DATE_TIME_Age = Key_details.age
DATE_TIME_DOB = Key_details.DOB
DATE_TIME_Thegai = Key_details.thegai
DATE_TIME_state = Key_details.State
DATE_TIME_district = Key_details.District
DATE_TIME_Address = Key_details.Address
DATE_TIME_Phone = Key_details.Phone
DATE_TIME_Profession = Key_details.profession
DATE_TIME_Salary = Key_details.salary
DATE_TIME_UG = Key_details.Under_Graduation_Degree
DATE_TIME_UGC = Key_details.Under_Graduation_college
DATE_TIME_PG = Key_details.Post_Graduation_Degree
DATE_TIME_PGC = Key_details.Post_Graduation_college
DATE_TIME_UG = Key_details.Under_Graduation_Degree
DATE_TIME_UGC = Key_details.Under_Graduation_college
DATE_TIME_PG = Key_details.Post_Graduation_Degree
DATE_TIME_PGC = Key_details.Post_Graduation_college
DATE_TIME_Rasi = Key_details.Rasi
DATE_TIME_Nakshatra = Key_details.Nakshatra
render_dict2['Age'] = DATE_TIME_Age
render_dict2['DOB'] = DATE_TIME_DOB
render_dict2['name'] = DATE_TIME_name
render_dict2['thegai'] = DATE_TIME_Thegai
render_dict2['State'] = DATE_TIME_state
render_dict2['district'] = DATE_TIME_district
render_dict2['Address'] = DATE_TIME_Address
render_dict2['Phone'] = DATE_TIME_Phone
render_dict2['profession'] = DATE_TIME_Profession
render_dict2['Under_Graduation_Degree'] = DATE_TIME_UG
render_dict2['Under_Graduation_college'] = DATE_TIME_UGC
render_dict2['Post_Graduation_Degree'] = DATE_TIME_PG
render_dict2['Post_Graduation_college'] = DATE_TIME_PGC
render_dict2['Rasi'] = DATE_TIME_Rasi
render_dict2['Nakshatra'] = DATE_TIME_Nakshatra
print(Key_details.Creator)
print(render_dict2)
return render(request,'Profilepage.html',render_dict2)
4) Formulate an HTML file for displaying the form: Corresponding changes to the HTML pages has to be performed.
Profilepage.html
<!DOCTYPE html>
<html style="font-size: 16px;">
<head>
<title>Profile</title>
{% load static %}
<link rel="stylesheet" href="{% static 'admin/css/Formpage.css' %}" media="screen">
