Hi alltogether
if I work in schemless-mode strange things are happening.
I start with an empty class »NewTest" using the activeOrient-Ruby interface
first_record = ThisTest.new_document attributes: { normal_array: [1,2,3,'z'
,'u'], some_link: "#33:0" }
Querying the class in studio returns this json
{
"result": [
{
"@type": "d",
"@rid": "#41:0",
"@version": 1,
"@class": "ThisTest",
"normal_array": [
1,
2,
3,
"z",
"u"
],
"some_link": "#33:0",
"@fieldTypes": "some_link=x"
}
],
(as expected)
Lets extend the record with an embedded list of links.
I expect the apearance of another @fieldtype-entry – but:
> first_record.update set: { link_array: [ "#32:0", '#32:3', '#32:29' ] }
=> #<REST::Model::ThisTest:0x00000003752850
@metadata={"type"=>"d", "class"=>"ThisTest", "version"=>2,
"fieldTypes"=>"some_link=x", "cluster"=>41, "record"=>0},
@attributes={"normal_array"=>[1, 2, 3, "z", "u"],
"some_link"=>"#33:0",
"created_at"=>2015-07-29 19:26:08 +0200,
"updated_at"=>2015-07-29 19:26:08 +0200,
"link_array"=>["#32:0", "#32:3", "#32:29"]}>
> first_record.link_array
=> [#<REST::Model::Minute:0x000000036c7070
@metadata={"type"=>"d", "class"=>"Minute", "version"=>1,
"fieldTypes"=>nil, "cluster"=>32, "record"=>0},
@attributes={"label"=>0, "created_at"=>2015-07-29 19:32:19 +0200,
"updated_at"=>2015-07-29 19:32:19 +0200}>,
#<REST::Model::Minute:0x0000000369fdb8
@metadata={"type"=>"d", "class"=>"Minute", "version"=>1,
"fieldTypes"=>nil, "cluster"=>32, "record"=>3},
@attributes={"label"=>3, "created_at"=>2015-07-29 19:32:19 +0200,
"updated_at"=>2015-07-29 19:32:19 +0200}>,
#<REST::Model::Minute:0x000000036967b8
@metadata={"type"=>"d", "class"=>"Minute", "version"=>1,
"fieldTypes"=>nil, "cluster"=>32, "record"=>29},
@attributes={"label"=>29, "created_at"=>2015-07-29 19:32:19 +0200,
"updated_at"=>2015-07-29 19:32:19 +0200}>]
Orientdb is using a smart autoloading-feature which resolves the links
correctly.
The result is similar to the findings in Studio.
The json confirms the activeOrient output: only one @fieldtype entry:
{
"result": [
{
"@type": "d",
"@rid": "#41:0",
"@version": 2,
"@class": "ThisTest",
"normal_array": [
1,
2,
3,
"z",
"u"
],
"some_link": "#33:0",
"created_at": "2015-07-29T19:26:08.313 02:00",
"updated_at": "2015-07-29T19:26:08.313 02:00",
"link_array": [
"#32:0",
"#32:3",
"#32:29"
],
"@fieldTypes": "some_link=x"
}
],
Why is the embedded list not included in @fieldtypes?
After reading the documentation I thought, the @fieldtypes are used to
define special data-formats and I want to implement a more robust
autoloading, which reflects the database-definitions rather then relying on
string-pattern.
Thanks in advance
