Wt

Hi there =)

I don't have a clue as to why this does not work.

My save routine saves some parts that are changed but not others.

Here are some additional infos

/// Object::persist looks like this:
{
    // As you can see there are field items that are unused in the save process at the moment

    // just recently found out that this would be unnecessary if Object would be Child class of Wt::Dbo::Dbo
    // this will be changed later and is hopefully not the culprit ... but it's on the agenda! ;-)
    Wt::Dbo::field(a, selfPtr, "selfPtr"); 

    Wt::Dbo::belongsTo(a, slotPtr, "calendarslot_calendaritem");
    Wt::Dbo::hasMany(a, collectionForRelation, Wt::Dbo::ManyToMany, "collection_object");
    Wt::Dbo::field(a, fieldDate, "planned_date");

    Wt::Dbo::field(a, fieldTimeStart, "planned_start");
    Wt::Dbo::field(a, fieldTimeEnd, "planned_duration");

    Wt::Dbo::field(a, t_confirmed_start, "confirmed_start");
    Wt::Dbo::field(a, t_confirmed_end, "confirmed_duration");

    Wt::Dbo::field(a, t_change_before, "changed_before");

    Wt::Dbo::field(a, fieldStringTitle, "title");
    Wt::Dbo::field(a, fieldStringInfo, "info");
}

/// Just for reference:
/// objItem := const Object*;
/// objPtr  := Wt::Dbo::ptr<Object>;
/// saveObject := Object*;

And here is the Save Routine that doesn't work as I think it should!

Wt::Dbo::Transaction t(DboSession::dataSession());

saveObject = objPtr.modify();

saveObject->collectionForRelation.clear();

for (CheckboxWithCollectionPtr *a : vec_CheckboxesWithPtr)
{
  // add to Collection for each item in vec_CheckboxesWithPtr that is checked
  if(a->isChecked())
  {
    // This Part is actually persisted even through reloads
    saveObject->collectionForRelation.insert(a->getPtr());
  }
}

// This part is not persisted
saveObject->fieldDate = dateEdit->date();
saveObject->fieldTimeStart = timeEdit_start->time();
saveObject->fieldTimeEnd = timeEdit_end->time();
saveObject->fieldStringTitle = lineEdit_Title->text();
saveObject->fieldStringInfo = lineEdit_Info->text();


Wt::log("notice") << "Flush Changes: " << saveObject->toString();
objPtr.flush();
if(t.commit())
{
  objItem = objPtr.get();
  Wt::log("notice") << "Flush Success: " << objItem->toString();
}

After commit a Widget is created that includes all of these Information and is displayed as it should!

Log shows that it was successful as well:

[/ VHyoYWmF0TviEISH] [notice] "Flush Changes: Date: 13.09.2019; Start: 07:00; End: 08:00; Title: Testitem in 2; Info: 13th 7-8"
commit transaction
[/ VHyoYWmF0TviEISH] [notice] "Flush Success: Date: 13.09.2019; Start: 07:00; End: 08:00; Title: Testitem in 2; Info: 13th 7-8"

After reload of the page then, there is an item created ... at the position where it should be, but without any information displayed.

In the Constructor I have this:

if(objItem == nullptr)
{
  // This never gets Called, as it's never shown in the logs
  // I just wanted to make sure it gets loaded
  Wt::log("notice") << "Constructor: objItem == nullptr";
  Wt::Dbo::Transaction t(DboSession::dataSession());
  objItem = objPtr.get();
}

Wt::log("notice") << "Constructor with Object: " << objItem->toString();

And for Items that were created just in the code, the log looks like this:

[/ VHyoYWmF0TviEISH] [notice] "Constructor with Object: Date: 13.09.2019; Start: 07:30; End: 08:45; Title: Testing Title; Info: Testing Info"

The others with the help of the Widget, look like this:

[/ VHyoYWmF0TviEISH] [notice] "Constructor with Object: Date: ; Start: ; End: ; Title: ; Info: "

The Item that was created in the code can be manipulated, but only the collection parts, not the field parts.

If there is any hint to get an idea of why that is messing up, please let me know.

Dbo::backend is SQLite3, Wt Version is 4.1.0, built and running on Ubuntu from source

What I understand from the way it behaves, is that an Object is created in the DB and persisted... but the changes for it are in parts somewhere going missing.

I will try to create a minimal Program to replicate ... but if you see something in the meantime, please let me know =)

Cheers
