Title:
Top-level fields in document cannot be indexed
Status in U1DB Qt/ QML:
Fix Released
Status in “u1db-qt” package in Ubuntu:
Fix Released
Bug description:
An index defined on a field at the root of a U1db.Document will
contain no data.
Example code below. It shows the results of two U1Db.Query/Indexes,
one of which is on a top-level field in the document and the other
not. The one on the top-level field does not work.
import QtQuick 2.0
import U1db 1.0 as U1db
Rectangle {
width: 600
height: 300
U1db.Database { id: db; path: "u1db-broken-query"; }
U1db.Document {
database: db; docId: "doc1"; create: true
defaults: { "topfield": { "subfield": "subvalue1" }, "toplevelfield": "topvalue1" }
}
U1db.Document {
database: db; docId: "doc2"; create: true
defaults: { "topfield": { "subfield": "subvalue2" }, "toplevelfield": "topvalue2" }
}
U1db.Index {
database: db
id: by_topfield_subfield
expression: ["topfield.subfield"]
}
U1db.Index {
database: db
id: by_toplevelfield
expression: ["toplevelfield.subfield"]
}
U1db.Query { id: qtopsub; index: by_topfield_subfield; query: [{subfield: "*"}] }
U1db.Query { id: qtoplevel; index: by_toplevelfield; query: [{toplevelfield: "*"}] }
Text {
id: h1
width: parent.width / 2
height: 50
anchors.left: parent.left
anchors.top: parent.top
horizontalAlignment: Text.AlignHCenter
text: "ListModel on topfield.subfield"
}
ListView {
anchors.top: h1.bottom
anchors.left: parent.left
width: h1.width
anchors.bottom: parent.bottom
model: qtopsub
delegate: Text {
text: JSON.stringify(model.contents)
}
}
Text {
id: h2
width: parent.width / 2
height: 50
anchors.right: parent.right
anchors.top: parent.top
horizontalAlignment: Text.AlignHCenter
text: "ListModel on toplevelfield"
}
ListView {
anchors.top: h2.bottom
anchors.right: parent.right
width: h2.width
anchors.bottom: parent.bottom
model: qtoplevel
delegate: Text {
text: JSON.stringify(model.contents)
}
}
}
