Description of Work Done

  • Sunburnt
    • The script Attached below installs the dependencies and also configures and installs Apache Solr and Sunburnt
  • Enabling text search:

-> Uncomment the following line in models/

# Uncomment this and set the solr url to connect to solr server for Full-Text Search
settings.base.solr_url = ""
  • Asynchronously Indexing and Deleting Documents:
    • The code for asynchronously indexing documents is in models/
    • Insertion: The code will first insert the document into the database. Then in callback onaccept it will index those documents calling the document_create_index() function from models/ . The following code should be added for enabling Full Text search for documents in any modules. The example is there, you can see modules/s3db/ in document_onaccept() hook.
    • Deletion: The code will first delete the record from the database table, then will select that file and will delete it from Solr also, by deleting its index which is stored in solr server. You can look for the code in modules/s3db/ in document_ondelete() hook.
    • In model()
              if settings.get_base_solr_url():
                  onaccept = self.document_onaccept # where document_onaccept is the onaccept hook for indexing
                  ondelete = self.document_ondelete # where document_onaccept is the onaccept hook for deleting
                  onaccept = None
                  ondelete = None
    • In onaccept()
              vars = form.vars
              doc = vars.file # Where file is the name of the 
              table = current.db.doc_document
                  name = table.file.retrieve(doc)[0]
              except TypeError:
                  name = doc
              document = json.dumps(dict(filename=doc,
                                   args = [document])
