InvalidCypherQuery

[jgwmaxwell]

Hi,

I was following the example in the Readme in IRB, and am coming across the following error whenever I try and save, count or find.

Save and find still work - it persists the record or finds it as expected, but it throws out this error first. This is true under REE, MRI 1.9.2p290 and JRuby 1.6.5 - if that helps.

Architect4r::InvalidCypherQuery: start root = node(0) match root-[r:model_root]->x where r.architect4r_type and r.architect4r_type = 'Instrument' return x
    from /home/john/.rvm/gems/ruby-1.9.2-p290/gems/architect4r-0.3.4.2/lib/architect4r/core/cypher_methods.rb:18:in `execute_cypher'
    from /home/john/.rvm/gems/ruby-1.9.2-p290/gems/architect4r-0.3.4.2/lib/architect4r/core/cypher_methods.rb:36:in `cypher_query'

    from /home/john/.rvm/gems/ruby-1.9.2-p290/gems/architect4r-0.3.4.2/lib/architect4r/model/queries.rb:13:in `count'
    from (irb):28
    from /home/john/.rvm/rubies/ruby-1.9.2-p290/bin/irb:16:in `'

I'd offer to bugfix, but I don't have a clue about Cypher!

In order to help you with your query problem, I would need more data about your graph. But I would guess, that your "where" clause should be " x.architect4r_type and x.architect4r_type = 'Instrument' ".

Using "x." you access the properties of the nodes, with "r." you access the properties of the edge.
