As discussed in #22

Is there a particular reason that you are going with use_filename=True here: https://github.com/klis87/django-cloudinary-storage/blob/master/cloudinary_storage/storage.py#L60

I'm trying to access the latest version through a canonical form that will ease discovery; I can always fork the repo and flip that bit but was wondering if there's something I've missed.

The title says it all.

One of the reasons why that's less than ideal is limits, e.g. Cloudinary's size limit for "raw" files is lower than for videos.

If I understand correctly, it's not an intended behavior.

I'm using the "default" setup (as shown on README.md), here is a piece of debug log during collectstatic:

Copying '/blahblah/build/media/instructions.jpg'

As you can see, stuff gets uploaded to /raw/.

I am using cloudinary-storage with wagtail and getting an NotImplementedError error.

Hey thanks for creating what I believe is the correct way to do this!

I'd like to request the ability to specify upload options: My specific use-case is incoming transformations.

I'm not entirely sure how this would be communicated to the storage layer but declaring the options on the model's field would be nice.

With pycloudinary the way they've supported this is to allow you to extend and override CloudinaryField.upload_options(). I don't like this style though as it's preferred to specify options like this as arguments to the field's constructor.

I'm having some issues using ImageField in models. After uploading an image via an admin form and then going back to do some edits on that newly created entity, I get File extension '' is not allowed... when hitting Save.

Is there a good way around this? Right now I feel like anything I try to do to avoid this error is hackish.

Thanks for the lib by the way, really helping me out!

In https://github.com/klis87/django-cloudinary-storage/blob/master/cloudinary_storage/app_settings.py#L45 it is assumed that settings.BASE_DIR exists, and while is is generated in the default settings, not all Django projects choose to use it.

This package should not rely on this settings to exist.

Hi, first thanks for the amazing project!

I want to upload my files in private mode, so they are only accessible by my application, is it possible with this backend?

I have checked the documentation and I haven't found anything regarding private mode.

Thanks!

Hi there, running collectstatic raises the following errors.

I am storing a profile picture for each user in our database.

class User(AbstractBaseUser, PermissionsMixin):
    profile_picture = models.ImageField(
        upload_to="profile_picture/",
        blank=True,
        null=True,
    )

Now, I would like to return a cropped or otherwise transformed version of the profile_picture to a client requesting it via a REST API. What method can I use to get a CloudinaryImage instance of the image?

An example of this is when you want to avoid adding a suffix for every filename you to add unique_filename: False in the dictionary value of options variable in _upload. I did this manually changing the inside of the library.

If a document is named using Windows styled path, the _save method causes problems.

def _save(self, name, content):
    # name is path\to\some\image\image.jpg on Windows machine
    name = self._prepend_prefix(name)
    # name becomes media/path\to\some\image\image.jpg if `settings.MEDIA_URL` is /media/
    ...

At the end, the resulting filename on cloudinary is something like media/\path\to\some\image\image_asdfghjk.jpg/ causing cloudinary to complain.

I think it will be nice if django-cloudinary-storage also works well on Windows. I can supply a fix which makes sure the name variable in _save is in unix style.

If I have a model that has an ImageField as an attribute, how can I delete the image each time I do model_instance.delete()? I've seen that there is the deleteorphanedmedia command, but I don't understand how to use it each time I delete something that has an image.
What extra steps do I need to add to achieve this so I stop having orphan images?

Please any help would be really be appreciated. Thank you

I'm trying to upload using the admin, and am getting

cloudinary.api.Error: File size too large. Got 28078738. Maximum is 10485760.

However, the file itself is only about 2MB. It has worked for the longest time and only recently have I seen this error. Thoughts?

For some reason https://github.com/klis87/django-cloudinary-storage/blob/master/cloudinary_storage/storage.py#L83 doesnt work anymore for raw files, at least according to tests. For example below url for some reason gets 404 https://res.cloudinary.com/dri8awewt/raw/upload/v1/static/bd5f98a5-4524-408f-882f-fe31786c9ab7 during tests, but when I check cloudinary, this file exists, but it has a different version, but in the past v1 worked anyway...

@tiagocordeiro @bufke any ideas?

Hello!

I am currently using django-cloudinary-storage with the naive, server-uploading method, where the user uploads the photo to the server and the server uploads it to Cloudinary. That works fine, but soon I will switch to client-uploaded images, where the user uploads the image directly to Cloudinary and then sends me the URL (or whatever Cloudinary returns).

Could some documentation be added to detail how I can support this method? What do I need to give Django to create these fields and how?

Currently getting this error when running deleteredundantstatic. It is happening in get_needful_files, and the tuple is coming from here in Django code I believe. Presumably, it should just be using the first paths value from the tuple? Not sure if I am missing configuration or anything but that is certainly possible as well.

AttributeError: 'tuple' object has no attribute 'values'

When uploading videos I get the cannot find valid magic files error if i use Filefield and if I use imagefield i get upload a valid image error

Hi there!

Do you think it would be hard to split static between Cloudinary and the "usual" manifest storage?Here is a use case I have: while Cloudinary's CDN is the best place for most of static stuff, a few critical resources (e.g. CSS) are pushed (with http2 push) on page load. Of course you can't push stuff from a different domain, so right now it's either CDN or http2 push. It would be nice to be able to skip CDN for some files.

One (simple) way of doing that is to override url() in my project. However, I'm not sure if it will not break something. What do you think?

Currently prefix is based on MEDIA_URL setting. It would be nice to have abbility to customize prefix via CLOUDINARY_STORAGE. I can make PR for this, if it's necessary.

I am trying to push my static files to Cloudinary but I am getting an error :
expected str, bytes or os.PathLike object, not NoneType

I am using Django 4.1.
django_errors.log

I jave attached my log file. I am not able to figure out why this is happening. please help

I tried to upload a video of about 20MB. It just keeps loading. Nothing happens!

The browser just keeps loading.

This package is awesome, but I have one question, when I query something that has an ImageField, how do I get the full path? Now I get only something like media/images/uploaded_image.png

NOTE: I'm using graphql to query this, so I don't know if there if the rest of the path is completed by the cloudinary tag in the template or something like that

Hi there!

Quick question: how do you apply Cloudinary's transformation to static media? Did I miss something in the README, or is there no way to transform static pictures at the moment?

I was trying to upload image to cloudinary by decreasing the quality of image. I run into this error while uploading image.
