[ckan-dev] error 500 internal server error

[Jason Tan]

Hi All,

I'm hoping someone might be able to throw some light on a problem I'm
seeing.

We have a collection with some resources.

When I click on the resource's link   - the red rectangle in the attached
screenshot (
https://www.data.sa.edu.au/dataset/tag-single-nucleotide-polymorphisms-snps-in-cyp1b1/resource/ad11e799-374c-44a3-8f5e-fc73dd2b0070)


I  get the following in the apache ssl error log:

/dataset/tag-single-nucleotide-polymorphisms-snps-in-cyp1b1/resource/ad11e799-374c-44a3-8f5e-fc73dd2b0070
render time 0.074 seconds

Running strace on apache I see this:

[pid 20379] read(22, "import os\nactivate_this = os.pat"..., 4096) = 406
[pid 20379]
stat("/etc/ckan/prd/apache-prd.wsgi/dataset/tag-single-nucleotide-polymorphisms-snps-in-cyp1b1/resource/acdb3aee-4270-4458-bf6f-97716b04a255",
0x7fff64364740) = -1 ENOTDIR (Not a directory)

Which is perfectly correct -  there is no directory at:
/etc/ckan/prd/apache-prd.wsgi/dataset/tag-single-nucleotide-polymorphisms-snps-in-cyp1b1/resource/acdb3aee-4270-4458-bf6f-97716b04a255

When I click on the button  Explore->Go To Resource  (yellow rectangle in
atached screenshot):

This URL  loads and displays the expected data:
https://www.data.sa.edu.au/storage/f/2014-06-27T04:19:20.451Z/cyp1b1cleaned3.ped


We're using:
mod_wsgi  on centos 5
with python 2.6.6
httpd-tools-2.2.15-31.el6.centos.x86_64
httpd-2.2.15-31.el6.centos.x86_64
mod_wsgi-3.2-3.el6.x86_64

And ckan was installed like this:
pip install -e 'git+https://github.com/ckan/ckan.git@ckan-2.1.1#egg=ckan'
.
 I gather that  for some reason mod_wsgi/CKAN  is not mapping a URL to a
filesystem path, but I'm not sure why or how to fix it.

Any pointers very gratefully received.

Thanks
Jason
