Compatibility with django-s3direct

[octavio2895]

Not sure how possible this is since imagekit and s3direct operate very differently (imagekit uses file objects and s3direct outputs URL strings).

Just wondering if anyone have managed to make them work.

[vstoykov]

If you are using some of the django storages that can work with S3 (like django-storages or django-s3-storage) then imagekit can create thumbnails. Probably you just need to create a helper function (template filter) that can accept URL generated from s3direct and return relative path to the configured storage.

I'm not sure if this is what you suggested but I tried manually setting the source as a relative path of a previously uploaded image like so:

{% with image_path="img/thumbs/luxor-100-200-6.jpg" %}
{% thumbnail '650x350' image_path %}
{% endwith %}

And I get the following traceback:

I tested the relative path on the django shell using the storage api and it did find the file. I think that the tag expects a file-like object not a path. Is there a way to make a file-like object without downloading and opening a file?

[vstoykov]

Actually you can but is kind of tricky. You need to mimic the logic of django.db.models.fields.files.FieldFile but without the field. Probably similarly how we are mimicking it in ImageKit with BaseIKFile and ImageCacheFile.

BaseIKFile is not the best solutions and I'm not suggesting it to use it as is, but instead to read more about Django's abstractions about files. You can came up with some lazy opening file to see if it will work in your case.

@tony you are hijacking the thread. Your issue is unrelated to to the issue described by the issue's author.

I'm kindly asking you to respect others and not polluting theirs threads with unrelated information.

You can create new issue where we can have discussion about your problem and if it is issue with ImageKit at all.

[vstoykov]

@octavio2895 did you managed to fix your problem? Do you think that ImageKit can be improved somehow or if you think that it is not related to ImageKit we can close the issue?
