These are repro instructions for
- https://github.com/matthewwithanm/django-imagekit/issues/369.
- https://github.com/etianen/django-s3-storage/issues/33
*UPDATE:* this is now fixed! [The fix](https://github.com/etianen/django-s3-storage/issues/33) was in django-s3-storage.
## S3 prep
First, create a new s3 bucket (ours is named `iktest-media` in this
example). We'll need your access keys and bucket name available in your
environment later, so go ahead and just export them now:
```shell
$ export AWS_ACCESS_KEY_ID=...
$ export AWS_SECRET_ACCESS_KEY=...
$ export AWS_S3_BUCKET_NAME=iktest-media # replace with your bucket name
```
Now clone the iktest repo:
```shell
$ git clone https://github.com/mgalgs/iktest.git
$ cd iktest
```
and upload the `IMG_20160609_183718.jpg` file from this repo to your new
bucket:
```shell
$ aws s3 cp IMG_20160609_183718.jpg s3://iktest-media/media/test_images/
```
Your bucket should now look like this:
```shell
$ aws s3 ls --recursive s3://iktest-media
2016-08-11 20:03:26 49093 media/test_images/IMG_20160609_183718.jpg
```
## Django prep
Install everything in a fresh virtualenv and bootstrap some data:
```shell
$ virtualenv env
$ . env/bin/activate
$ pip install Django==1.9 django-s3-storage Pillow git+git://github.com/matthewwithanm/django-imagekit.git@develop
$ python manage.py migrate
$ python manage.py testdata
```
## Running the app
You're now ready to run the dev server:
```shell
$ python manage runserver
```
Load [http://localhost:8000](http://localhost:8000) in your web browser.
You'll notice that the first time you load the page it will complain with:
```

If you *reload* your page it will work(!). However, the thumbnails that
got generated won't actually be valid. Compare the urls from your web
browser to:
```shell
$ aws s3 ls --recursive s3://iktest-media
```
