hi
I want to take the photo file selected in the form using opencv and encode
the face using face_recognition in Django before my information is saved in
the database. But I can't get the photo file from cleaned data. please Help
me
my views.py
from django.shortcuts import render, redirect
from django.views import View
from .models import ImageEncode
from .forms import CreateEncodeImage
from django.contrib import messages
import cv2, os
import face_recognition
from django.conf import settings
class AddCustomFaceView(View):
form_class = CreateEncodeImage
path = os.path.join(settings.BASE_DIR, 'face_lib/')
def get(self, request, *args, **kwargs):
form = self.form_class
return render(request, 'home/custom-face.html', {'form': form})
def post(self, request, *args, **kwargs):
form = self.form_class(request.POST, request.FILES)
if form.is_valid():
new_face = form.save(commit=False)
img_name = form.cleaned_data['imgname']
img_add = form.cleaned_data['imgaddress']
img_face = cv2.imread(f'{img_add}')
img_face = cv2.cvtColor(img_face, cv2.COLOR_RGB2BGR)
face_loc = face_recognition.face_locations(img_face)
y1, x2, y2, x1 = face_loc
y1, x2, y2, x1 = y1, x2, y2, x1
image_frame = img_face[y1:y2, x1:x2]
encode = face_recognition.face_encodings(img_face)
if encode:
new_face.imgencode = encode[0]
new_face.imgname = img_name
new_face.imgaddress = form.cleaned_data('imgaddress')
new_face.save()
cv2.imwrite(self.path + img_name, image_frame)
messages.success(request, 'New Custom Face Saved', 'success')
else:
messages.warning(request, 'could not save this face', 'success')
return redirect('home:face_custom')
return redirect('home:list_img')
else:
messages.warning(request, 'not valid data', 'warning')
return redirect('home:face_custom')
my forms.py
from django import forms
from .models import ImageEncode
class CreateEncodeImage(forms.ModelForm):
class Meta:
model = ImageEncode
fields = ('imgname', 'imgaddress',)
my models.py
import numpy as np
from django.db import models
from ndarraydjango.fields import NDArrayField
class ImageEncode(models.Model):
imgencode = NDArrayField(shape=(32, 4), dtype=np.float64)
imgname = models.CharField(max_length=100, null=False)
imgaddress = models.ImageField(upload_to='face_lib/', null=False)
created = models.DateTimeField(auto_now_add=True)
