OrientDB: filter by entire embedded field value - orientdb

Question

I'm to insert a record with embedded field in OrientDB and then to query for that record using filter:
insert into MyClass set embeddedField = {'#type': 'd', 'id': 1}
works well, and
select from MyClass
returns the record I've added. But when I add where with filter for embeddedField, I get no results:
select from MyClass where embdeddedField = {'#type': 'd', 'id': 1}
I thought that it could happen because Orient adds #version field into embedded document, so I tried to search with version:
select from MyClass where embdeddedField = {'#type': 'd', '#version': 0, 'id': 1}
But still got no results.
Question: Any idea how to filter embedded field by entire document? Without the need to filter explicitly by each field of embedded document:
select from MyClass
where embdeddedField.id = 1
and embdeddedField.field2 = val2
and embeddedField.field3 = val3
Because for several reasons I would like to pass the entire object as single query parameter:
select from MyClass where embdeddedField = ?

Answer 1

Thats because the provided Hash is transformed to an embedded class.
Perhaps take a look at the ActiveOrientWiki https://github.com/topofocus/active-orient/wiki/Relations
To explain:
Take a class base, there a document with two properties (schemaless)
and add existing documents to it
( 0..9 ).each do | b |
base_record= Base.create label: b, first_list: []
( 0..9 ).each {|c| base_record.first_list << FirstList.create( label: c ) }
end
INFO->CREATE VERTEX base CONTENT {"label":0,"first_list":[]}
INFO->CREATE VERTEX first_list CONTENT {"label":0}
INFO->update #136:0 set first_list = first_list || [#147:0] return after #this
then links are embedded and the record looks like
=> #<Base:0x00000000041a60e0 #metadata={:type=>"d", :class=>"base", :version=>11, :fieldTypes=>"first_list=z", :cluster=>129, :record=>1},
#attributes={:first_list=>["#149:1", "#150:1", "#151:1", "#152:1", "#145:2", "#146:2", "#147:2", "#148:2", "#149:2", "#150:2"], :label=>"1"}>
if you expand the list items, you can query for "#type"
If you add a document without rid, the same thing happens
( 0..9 ).each {|c| base_record.first_list << FirstList.new( label: c ) }
20.04.(12:53:59) INFO->update #130:2 set first_list = first_list || [{ #type: 'd' ,#class: 'first_list' ,label: 0 }] return after #this
INFO->CREATE VERTEX base CONTENT {"label":"c","first_list":[]}
'#130:2'.expand
=> #<Base:0x00000000043927a0 #metadata={:type=>"d", :class=>"base", :version=>11, :fieldTypes=>"first_list=z", :cluster=>130, :record=>2},
#attributes={:first_list=>["#151:12", "#152:12", "#145:13", "#146:13", "#147:13", "#148:13", "#149:13", "#150:13", "#151:13", "#152:13"], :label=>"c"}>
If you omit the class-name, only the scope of the rid's changes
INFO-> update #132:2 set first_list = first_list || { #type: 'd' ,label: 0 } return after #this
=> [#<Base:0x0000000003a26fb8 #metadata={:type=>"d", :class=>"base", :version=>3, :fieldTypes=>"first_list=z", :cluster=>132, :record=>2},
#attributes={:first_list=>["#3:0"], :label=>"d"}>]
In any case, a query for #type failes
