I am attempting to add a collection, and am getting a 405 Method Not Allowed error.  DSpace 6.3.  Thanks in advance for any suggestions! --Paul

In the output below, note the line: < Allow: DELETE,GET,OPTIONS,PUT

POST is not on the list!  Why?

According to the documentation, creation of a collection uses a POST request. 
https://wiki.lyrasis.org/display/DSDOC6x/REST+API#RESTAPI-Communities

Here is the server output:

In anticipation of possible questions, here is the way I make the REST call:

I allow Tomcat access only on localhost, and my script is on the same machine.  I make the call with curl:

add_cmd = ['curl', '-v', '--cookie', self.sessionid, '--header', 'Content-Type: application/json', '-X', 'POST', item_link, '-d', json_str]

json_str = '''
{
        "copyrightText": "",
        "expand": [
            "parentCommunityList",
            "parentCommunity",
            "items",
            "license",
            "logo",
            "all"
        ],
        "introductoryText": "Willkommen zu der neue Sammlung 1!",
        "items": [],
        "license": null,
        "logo": null,
        "name": "Neue Sammlung 1",
        "shortDescription": "eine Sammlung via REST erzeugt",
        "sidebarText": "",
        "type": "collection"
    }
'''

Thanks,
Paul

Hi Paul,

It looks (to me) like you are POSTing to the wrong endpoint (based on the docs you linked to)

Your POST looks like this:

POST /rest/communities/cb69484b-1669-4832-b0aa-8acb902db531

But, the correct POST to create a collection is:

POST /rest/communities/cb69484b-1669-4832-b0aa-8acb902db531/collections

So, the error you are seeing is correct.  You cannot POST to just the /communities/{uuid} endpoint...that endpoint only accepts GET (to get info about that Community), DELETE (to delete that community) and PUT (to update that community).  If you want to add a collection, you have to POST to the /collections subresource for that community.

Hopefully that helps!

Tim

Hi Tim,

Thanks for your very nice reply!  You saved me considerable time, but I am sorry to have wasted your time with such a dumb mistake.  :-(

Best regards,
Paul
