[Ckan-users] CKAN DataStore problem

• Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Hi,

First, what's the link to see the ckan forum list?


During the installation of DataSote extension I had a problem regarding the
datastore set permissions.
Problem that Mat Witts was kind to explain and solve:
http://stackoverflow.com/questions/34271329/ckan-datastore-set-permissions/34308811#34308811

Now I had other problems on the installation of DataStore...
(I´m using the official documentation  for a installation from source on
CentOS - http://docs.ckan.org/en/ckan-2.2/datastore.html
<http://docs.ckan.org/en/ckan-2.2/datastore.html#set-permissions>)


 I made

paster datastore set-permissions postgres -c /etc/ckan/default
/development.ini

result was:  Set permissions for read-only user: SUCCESS

After to Test the set-up

curl -X GET
http://127.0.0.1:80/api/3/action/datastore_search?resource_id=_table_metadata
<http://127.0.0.1/api/3/action/datastore_search?resource_id=_table_metadata>

result was:
{"help": "Search a DataStore resource.\n\n    The datastore_search action

"/api/3/action/datastore_search?resource_id=_table_metadata", "next":
"/api/3/action/datastore_search?offset=100&resource_id=_table_metadata"},
"total": 2}

I think that's ok, no?

Than, following the documentation, To test the whether the set-up allows
writing, you can create a new DataStore resource. To do so, run the
following command:

curl -X POST http://127.0.0.1:80/api/3/action/datastore_create -H
"Authorization: {378f0d31-ffe7-4f40-916a-d4e372fe372e}" -d '{"resource_id":
"d70df5a0-6e38-47a9-a37e-10e37b9f0852}", "fields": [ {"id": "a"}, {"id":
"b"} ], "records": [ { "a": 1, "b": "xyz"}, {"a": 2, "b": "zzz"} ]}'

result

The folder where the file that correspond to the resource have all
permissions
[image: Imagem intercalada 1]

as well the file it self:
[image: Imagem intercalada 2]


Hope that the my problem could be understand
(I am not an IT guy, so some of my doubts may seem pretty basic / strange)

thanks in advance
