Introduction to Django ImageField

The following article provides an outline for Django ImageField. There is a need to store and process images in web applications; the same necessity also stays with Django-based image applications. So, you can flexibly declare and process the image fields in Django. Declining the image-based fields and retrieving the images is comparatively straightforward in Django applications. The field declared as an image field needs to be associated with an URL location in the background, and the specific file will be brought back when a retrieval request is raised. This is how the image-level field storage and retrieval occur in the background. This null value will also be considered for whichever records the image is not uploaded.

Syntax of Django ImageField

Here is the syntax for declaring image fields in Django:

Foreignkey name = models.ImageField(null_argument,blank_argument ,uploadto_argument)

Here the first argument represents a null argument. This means that the null value is used to indicate that no image has been uploaded for certain records. The null value will be considered for records where the image has not been uploaded. Additionally, the blank argument corresponds to the value when an empty or blank value is associated with the image field argument.

The last argument is the upload to the argument. This is a very critical argument. This argument determines the location of chúng tôi will consider the location where we must store the loaded documents chúng tôi we will consider the path of the documents given here, and we will store the reports at the mentioned location. This is how we carry out the document storage location.

Creation of Django ImageField

Given below shows the creation of Django ImageField:

1. Changes in chúng tôi file

As the syntax section mentions, the image field must be declared in the chúng tôi file. We notice that the image field is declared the last field in the model.

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

The media root and URL files must be updated to the chúng tôi file. In addition, the path of the media files needs to be mentioned here for these variables.

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 the chúng tôi file

Instantiate the media root and document root variables inside the chúng tôi file as shown below.

The changes for the chúng tôi file are as follows:

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 image 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 given in the below-given chúng tôi section.

views.py:

@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

Profilepage.html:

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

Output:

Conclusion

This article explains how to declare the Image field in a Django setup and render the changes to an HTML page, displaying the image at the desired position. The article also covers how to control the padding of the image using the HTML division on the page.
