How to fix not enough arguments for format string?

Question

Django

Updated easy-thumbnails to latest version and stopped working!

from django.http import HttpResponsePermanentRedirect, HttpResponseNotFound, HttpResponseBadRequest
from django.core.files.storage import default_storage
from easy_thumbnails.files import get_thumbnailer
from easy_thumbnails.exceptions import InvalidImageFormatError
import re

SIZE_RE = re.compile(r'^(\d+)x(\d+)$')

def resize(request, path):
  thumbnail_opts = {}
  if 'size' in request.GET:
    if SIZE_RE.match(request.GET['size']):
      thumbnail_opts['size'] = map(int, request.GET['size'].split('x'))
      if 'crop' in request.GET:
        thumbnail_opts['crop'] = request.GET['crop']
    else:
      return HttpResponseBadRequest('Неверный формат. ')
  else:
    return HttpResponsePermanentRedirect(default_storage.url(path))
  try:
    thumbnailer = get_thumbnailer(default_storage, path)
    thumbnail = thumbnailer.get_thumbnail(thumbnail_opts)
    return HttpResponsePermanentRedirect(thumbnail.url)
  except IOError:
    return HttpResponseNotFound('Файл не найден')
  except InvalidImageFormatError:
    return HttpResponseBadRequest('Файл не является изображением.')

TypeError: not enough arguments for format string

Answer 1

The problem is probably that in the regular expression the numbers are separated by a comma, and you are trying to split them by 'x'. Accordingly, thumbnail_opts['size']you get one element instead of the expected two.

Answer 2

throw arguments
or fix the code
