Nodes not printing, error: line 1:100 missing '::path' at '<EOF>'

[afidegnum]

apache-age-python returns an error over result formatting. from the AGEviewerer, this query successfully prints the results as right-left nodes containing the list of the right nodes as shown below:

          SELECT * from cypher('text_test', $$
          MATCH (V:node)-[connect]->(V2:node)
			WITH V as parent, COLLECT(V2) as children
          RETURN parent, children
$$) as (parent agtype, children agtype);

and the result below:

while using the same procedure on apache-python-age, here is the resulting output.

age.setUpAge(conn, GRAPH_NAME)

Care to look into it ?

The same applies to this:

import age
from age.gen.ageParser import *
GRAPH_NAME = "text_test"

DSN = "host=localhost port=5432 dbname=texttest user=afidegnum password=demo001"
ag = age.connect(graph=GRAPH_NAME, dsn=DSN)

def graph_one():
    children = ag.execCypher("MATCH (V:node)-[connect]->(V2:node) WITH V as parent, COLLECT(V2) as children RETURN {parent: parent, children: children}")
    for c in children:
        print(c)
        #graph_nodes(c[0].id)

and the result obtained:

[afidegnum]

you can have a look at my notebook

[rhizome-ai]

AGE is upgraded. So some cypher specs were added. I will fix soon.

[afidegnum]

Thanks

[rhizome-ai]

I've just update version v0.0.4. Please pull repository again.

[afidegnum]

Thanks a lot, let me try it again

[afidegnum]

is age.gen.ageParser no more available on the new version?

[afidegnum]

the following errors were encoutered:

[rhizome-ai]

Yes, type parser name(age.gen.ageParser) was changed to age.gen.AgtypeParser .

And previous error, it seems like that AGE extension is not loaded( 'LOAD AGE' ) on age DB.

Please check.

everything is ok now
