iphone - Core Data: Returning to a Previously Inserted Managed Object -

-

i have following model: 

doctor <-->> case <->> report

a doctor has many cases case has 1 doctor. case can has many reports

i generated classes representing model, , inserted 1 doctor, 1 case 1 report.

how can return doctor , associate case , same report?

any example one-to-many core data insertion , display.

best regards

when insert managed object pointer object back. assuming have nsmanagedobject subclass of doctor, create new doctor object this:

doctor *newdoc=[nsentitydescription insertnewobjectforentityforname:@"doctor"                                                 inmanagedobjectcontext:mymanagedobjectcontext];

newdoc pointer doctor object , can treat other object. can retain reference way e.g. instance attribute, array, set etc. can retrieve , add new case object so:

[newdoc addcaseobject:anewcase];

...and same add report case. these methods defined in autogenerated subclasses.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
