I am trying to create a epaper web app, in which admin can upload file in pdf format and which is converted to image while rendering the page from client side. I have tried pdf2image but getting error something like this:
PDFPageCountError at /city_list
Unable to get page count.
I/O Error: Couldn't open file '['/media/pdf/Akola/2020/04/24/page01.pdf']': No such file or directory.
here is my code:
models.py
class City(models.Model):
cityid =models.AutoField(primary_key=True)
name = models.CharField( max_length=50)
def user_directory_path(instance, filename):
# file will be uploaded to MEDIA_ROOT/user_<id>/<filename>
ab = instance.date.strftime("%Y/%m/%d")
return 'pdf/{0}/{1}/{2}'.format(instance.city.name,ab, filename)
class DailyFeed(models.Model):
city = models.ForeignKey(City, on_delete=models.CASCADE)
date =models.DateField(auto_now=False, auto_now_add=False)
page1 = models.FileField(upload_to=user_directory_path)
page2 = models.FileField(upload_to=user_directory_path)
page3 = models.FileField(upload_to=user_directory_path)
views.py:
def city(request):
city_list = City.objects.all()
daily = DailyFeed.objects.filter(date=timezone.now().date()).filter(city__name = "Akola")
ab = [pdfurl.page1.url for pdfurl in daily ]
path = r'{}'.format(ab)
a = str(path)
pages = convert_from_path('{}'.format(a), 200)
for pdf in pages:
pdf.save('{}.jpg'.format(a.name[:-4]), 'JPEG')
return render (request,'main.html',{'city_list':city_list,'page':pdf})
urls.py
re_path(r'^city_list',views.city,name='city'),
I am have not getting where I am going wrong?
use path instead of url. URL is not where the file is, but how the browser can access it
[pdfurl.page1.url for pdfurl in daily ]
to
[pdfurl.page1.path for pdfurl in daily ]
