Ошибка неверного образа в Django, но PIL установлен и проходит все тесты

3 голосов
/ 21 января 2010

Итак, я, наконец, успешно установил PIL (после многих трудностей) на RHEL5 с Django (версия для разработки) и Python 2.6, установленным в /opt/python2.6.

Запуск selftest.py показывает, что все появляетсядля правильной установки: 

$ python2.6 selftest.py 
57 tests passed.

Я могу загрузить файлы .png и .gif без проблем, но у меня возникают проблемы при попытке загрузить файлы .jpg с помощью ImageField: «Загрузить действительное изображение. ФайлВы загрузили не изображение или не поврежденное изображение. "

Я видел этот другой вопрос и запустил тест, чтобы проверить, будет ли PIL проверять изображение, и он это сделал: 

>>> from PIL import Image
>>> trial_image=Image.open("/tmp/jordanthecoder.jpg")
>>> trial_image.verify()
>>>

Что может происходить?Очевидно, что разрешение JPEG является своего рода важным.Я понимаю, что один из вариантов - использовать вместо этого FileField, а затем убедиться, что это один из файлов GIF, PNG или JPEG, но я бы предпочел использовать встроенный объект.

В случае, если этополезно, вот подробное отображение оболочки выше:

ОБНОВЛЕНИЕ № 2:

Хорошо, поэтому я решил вообще обойти ImageField и просто посмотреть, что делает PIL самостоятельно.Это код вопроса (в моем файле views.py): 

def test_image(request):
    i = Image.open("/tmp/jordanthecoder.jpg")
    t = i.verify()
    return HttpResponse("Image is "+repr(i.info))

Это вывод веб-страницы: 

Image is {'jfif_version': (1, 1), 'jfif': 257, 'jfif_unit': 1, 'jfif_density': (72, 72), 'dpi': (72, 72)}

UPDATE # 3

Итак,это модули и пути для двух разных систем.Я не совсем уверен, почему они такие разные и что я могу сделать, чтобы изменить поведение веб-версии.

Они на самом деле использовали разные модули JSON, почти уверен, что это не имеет значения.Помимо этого, здесь есть разные модули.Предположим, что все эти модули находятся где-то в /opt/python2.6/...

Только в веб-версии: 

django.contrib.sessions.*, django.core.email, django.core.handlers.*, django.core.mail, django.core.mimetypes, django.core.os, django.core.random, django.core.smtplib, django.core.socket, django.core.time, django.middleware.*, email.*, encodings.ascii, hmac, mimetypes, mod_wsgi, smtplib, uu

Только в версии оболочки: 

code, codeop, django.core.management.*, readline, rlcompleter, settings, user

Спасибо

Похоже, проблема в том, что apache использует неправильный libjpeg.so, тогда как python использует правильный.Я создал более обобщенную версию вопроса, не относящуюся к Django.

У меня сложилось впечатление, что проблема PIL JPEG заключается в том, что это почти всегда проблема конфигурации системы.

Вы создали и настроили PIL и протестировали с этой версией, и это сработало. Итак, я предполагаю, что Django использует другой PIL, возможно, построенный без поддержки JPEG или не может найти libjpeg.

Вы можете подтвердить это, выполнив тест снова, но используя python -v manage.py shell вместо прямого запуска python2.6. Здесь вы должны быть осторожны и убедиться, что ваш исполняемый файл python и PYTHONPATH точно соответствуют тому, что загружено вашим веб-сервером.
