Django Image Processing Webapp Part VI

In this part we will add the name of user to our imageEnhance model.

Edit Image/models.py add an extra attribute to out imageEnhance.

.................................................
from django.conf import settings
.................................................
# Create your models here.
class ImageEnhance(models.Model):
    title = models.CharField(max_length=50)
    image = models.ImageField(upload_to="",blank=True,null=True)
    image_enhanced = models.ImageField(upload_to="",blank=True,null=True)
    filter = models.CharField(max_length=50,blank=True,null=True)
    likes = models.IntegerField(blank=True,null=True)
    created_at = models.DateTimeField(auto_now_add=True,blank=True,null=True)
    #adding the author
    author = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,null=True,blank=True)
................................................

Now, edit Image/views.py to add the author.

from django.shortcuts import render
from django.http import HttpResponse
from django.core.paginator import Paginator,PageNotAnInteger, EmptyPage
from django.contrib.auth.decorators import login_required

from django.contrib.auth import get_user

from .models import ImageEnhance
from .forms import ImageForm

# Create your views here.


...............................................................

@login_required    
def imageForm(request):
    if request.method == 'POST':
        form = ImageForm(request.POST,request.FILES)
        user = get_user(request)
        if form.is_valid():
            #save the model instance
            instance = form.save(commit=False)
            instance.author = user
            print("++++++++++++++++++++++",instance.author)

            instance.grayscale()
            instance.save()
            #latest_object = ImageEnhance.objects.latest('id')
            #latest_object.grayscale()

            return render(request,"image_process.html",{"form":form,'object':instance,"filter":"Not Processed"})
        else:
            latest_object = ImageEnhance.objects.latest('id')
            
           ......................................................
    else:
        user = get_user(request)
        form = ImageForm(initial={'author':user})
       

    return render(request,"image_form.html",{'form':form})

Now add the author to the enhanced image if the user exists. Edit image_home.html

..................................................................
              <img src="{{ im.image_enhanced.url }}" width="400" height="400">
              <br>
              <small class="card-text">{{im.created_at}} </small>
              <br>
              {% if im.author %}
              <small class="card-text">Author: {{im.author}} </small>

              {% endif %}
