I need to import some data from a excel file and a folder with images, every row in the excel describes every entry and have a list of filenames in the folder (photos related to the entry).
I’ve done a script which creates every entry in the database and saves it trough the django shell, but i have no idea how to instantiate a InMemoryUploadedFile for save it with the model.
In django 1.0 I had this small class which allowed me to do what i need, but with changes in django 1.1 it’s not working any more.
class ImportFile(file): def __init__(self, *args, **kwargs): super(ImportFile, self).__init__(*args, **kwargs) self._file = self self.size = os.path.getsize(self.name) def __len__(self): return self.size def chunks(self, chunk_size=None): self._file.seek(0) yield self.read()
I was using this class with this piece of code to load images and saving them with the model instance.
for photo in photos: f = ImportFile(os.path.join(IMPORT_DIR, 'fotos', photo), 'r') p = Photo(name=f.name, image=f, parent=supply.supply_ptr) name = str(uuid1()) + os.path.splitext(f.name) p.image.save(name, f) p.save()
The question is, how do I create a InMemoryUploadedFile or TemporaryUploadedFile from a file in python?, or any other thing that could work in this context.
Finally I found the answer.
from django.core.files import File f = File(open(os.path.join(IMPORT_DIR, 'fotos', photo), 'rb')) p = Photo(name=f.name, image=f, parent=supply.supply_ptr) name = str(uuid1()) + os.path.splitext(f.name) p.image.save(name, f) p.save()
