Remove Django-jfu and automatically change the same file name

To install Django-jfu, see:

Https://pypi.python.org/pypi/django-jfu

Upload a file using Django-jfu. If the file name is the same, the "_" 1.jpg suffix will be automatically added, for example, 2d7f977e6b36ec616b4e31a33d988c13_1.jpg. We will remove this feature to overwrite the original file.

File: Views. py

Def upload (request ):

Instance. Save ()

Basename = OS. Path. basename (instance. file. Path)

File_dict = {

'Name': basename,

'SIZE': file. size,

'Url': settings. media_url + basename,

'Thumbnailurl': settings. media_url + basename,

'Deleteurl': reverse ('jfu _ delete', kwargs = {'pk': instance. PK }),

'Deletetype': 'post ',

}

Return uploadresponse (request, file_dict)

The original Instance. Save () method will automatically call Django. Core. Files. Storage. filesystemstorage. get_available_name () method. We need to rewrite this method.

Add the following to views. py:

From Django. Core. Files. Storage import filesystemstorage

From Django. DB import models

Class overwritestorage (filesystemstorage ):

Def get_available_name (self, name ):

If self. exists (name ):

OS. Remove (OS. Path. Join (settings. media_root, name ))

Return name

Class photo (models. Model ):

File = models. filefield (upload_to = "/data/Media/", storage = overwritestorage ())

The upload_to directory here is consistent with the settings. media_root directory.

Class photo is not written to model separately. in py, because model. when importing views from overwritestorage in Py, an error is reported, which may be views-> model, but modey-> views cannot be correlated.

Now, the modified file name will automatically overwrite the previous file name.

You also need to modify the update_delete function. Otherwise, one file cannot be deleted.

File: Views. py

Def upload_delete (request, PK ):

Success = true

Try:

Instance = photo. Objects. Get (PK = PK)

If OS. Path. isfile (instance. file. Path ):

OS. Unlink (instance. file. Path)

Instance. Delete ()

Failed t photo. doesnotexist:

Success = false

Return jfuresponse (request, success)

As follows:

The file format of .tar.gz can be uploaded and can be modified:

File: photo_upload_form.html

{% Extends 'jfu/upload_form.html '%}

{% Block js_opts %}

Sequentialuploads: True,

Acceptfiletypes:/(\. | \/) (PNG | GIF | jpe? G | tar.gz) $/I

{% Endblock %}

You can modify the thumbnail in front of server.tar.gz:

File: upload_form.html

About 304 rows:

Add a judgment. If the image cannot be found, use the default one.

OK, this problem of automatically adding suffix names has caused me a whole day.
