示例1: _file_save
# 需要导入模块: from django.core.files.uploadedfile import InMemoryUploadedFile [as 别名]
# 或者: from django.core.files.uploadedfile.InMemoryUploadedFile import open [as 别名]
def _file_save(self, new_pil_obj, version, format, model_instance, file):
"""Save our version files to disk"""
img_version_buffer = StringIO.StringIO()
new_pil_obj.save(img_version_buffer, format)
img_version_buffer = InMemoryUploadedFile(
file=img_version_buffer,
field_name=None,
name='foo',
content_type='image/%s' % format,
size=img_version_buffer.len,
charset=None)
img_version_buffer.open() # reopen just in case, which sets Django's File-like object to seek=0
filename = version['upload_to'](model_instance, file.name)
# delete first to prevent save() from possibily creating a new uniquely named file
# we want to replace the file, which save() may not do natively
file.field.storage.delete(filename)
file.field.storage.save(filename, img_version_buffer)示例2: test_open_resets_file_to_start_and_returns_context_manager
# 需要导入模块: from django.core.files.uploadedfile import InMemoryUploadedFile [as 别名]
# 或者: from django.core.files.uploadedfile.InMemoryUploadedFile import open [as 别名]
