wfs t - Failed to insert data to geoserver layer with WFS-T

I am trying to make a POST request to geoserver in order to Insert a new feature. I am using the example provided by the Demo section of geoserver.

I have modified it as following:

  xmlns:wfs="http://www.opengis.net/wfs"

  xmlns:geonode="http://www.openplans.org/geonode"
  xmlns:gml="http://www.opengis.net/gml">
  
   
   
    
      
        
          
            88.247354197,21.438097723 89.247354197,18.438097723

          
        
      
     
    
   alley
  
 

When trying to execute it I get a message:

 Feature type 'bgd_uti_transmissionline_nrel' is not available:

Any idea why this is happening?

EDITED I tried to make a DescribeFeature request as:

  version="1.0.0"
  service="WFS"
  xmlns="http://www.opengis.net/wfs"
  xmlns:topp="http://www.openplans.org/topp"

  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.opengis.net/wfs http://www.opengis.net/wfs">
  geonode:bgd_uti_transmissionline_nrel    

I did the request through the Demo section of geoserver. I get nothing back. Checking the Developer's tools, I see the request is pending.

EDIT II

I did the DescribeFeature request using PYTHON Requests and I get something meaningful:

When I tried to do the InsertFeature request using PYTHON Requests, I got this error:

 Feature type 'bgd_uti_transmissionline_nrel' is not available: 
 

Answer

There were two issues in my requests. The first one was related with the URL. Initially I was using this URL:

url = 'http://localhost:8080/geoserver/wfs'

Including my_workspace name in the URL is necessary for this WFS-T Insert (according to here):

url = 'http://localhost:8080/geoserver/my_workspace/wfs'

The second issue was related with the namespace I have defined: geonode In the end the xml I used looked like this:

 xmlns:wfs="http://www.opengis.net/wfs"
 xmlns:gml="http://www.opengis.net/gml">
   
    
     

      
       
        
         
         39.247354197,21.438097723 89.247354197,18.438097723
         
       
     
    
   

  
 

The rest of the request command (using PYTHON Requests lib) is straightforward:

headers = {'Content-Type': 'application/xml'}

print requests.post(url, data=xmlstr, headers=headers, auth=('geoserver_user', 'geoserver_pass')).text

The problem to solve now is how to pass non spatial data in the request. Meaning values of the attributes.
