One2Many Issue

[salahzidi]

You can get it by using the "ODataRow" function: yourDataRow.getO2MRecord(yourOneToManyItemId)

[maanu]

I know that function.but it fails to work in case of using cursor Loader as you might know that it uses pure SQLITE database for fetching record.so it doesn't store value in table that has ONE side key..we can only use M2O relationship.It causes null pointer exception when I'm trying to fetch record as you suggest.

Hello,

It is not possible to directly access one to many record using CursorLoader.

CursorLoader create cursor record set which are related to your table column. It not automatically handle relations such as One2Many or Many2Many.

For accessing one 2 many record when you are binding your view with record cursor you have to just fetch ODataRow using your database object by db.select(your cursor's _id row value as int) and than you can get your one 2 many record by datarow.getO2MRecord("column").browseEach().

E.g:

ODataRow row = db.select(cr.getInt(cr.getColumnIndex("_id"));

Also, you can specify your specific column to fetch record by ignoring other columns.

db.select(new String[]{"my_relation_column"}, cr.getInt(cr.getColumnIndex("_id"));

Hi,
please tell me if odoo mobile framwork manage access rights based on groups?

@maanu Refer Odoo Mobile documentation (v2) http://mobile.odoo.co.in/v2

@SELKHOUFAIRI Odoo Mobile framework uses JSON-RPC for getting and submitting data on server. Odoo Server check access rights based on RPC calls. So on mobile, we don't need to check for access rights of user, it already checked by server on your request for data.

Hi, currently I am working on a mobile app with Odoo mobile framework which is supposed to use some features of the survey module (answer questions from the mobile app), at first I just try to fetch the questions.
Models are structured in this way:
Survey.survey has a relationship o2many with survey.page, and survey.page has another o2many relation with survey .question, I retrieve the pages well into the activity surveyDetail like this:
…
survey = new SurveySurvey(this, null);
…
int rowId = extras.getInt(OColumn.ROW_ID);
record = survey.browse(rowId);
…
List lines = record.getO2MRecord("page_ids").browseEach();

The problem is that I do not get the questions in PageDetail with this:
…
record = page.browse(rowId);
…
List lines = record.getO2MRecord("question_ids").browseEach();

I get null but there are questions in server.
And Whereas this: record.getO2MRecord("question_ids") I have this in log: odoo.core.orm.OO2Mrecord@41896e98
can I have your support?
