        ModGer = Model.setStringList(GerKey)
        completer = QtGui.QCompleter()
        CompAra = completer.setModel(ModAra)
        ComGer = completer.setModel(ModGer)
        self.LineEditAra.setCompleter(CompAra)
        self.LineEditGer.setCompleter(ComGer)

Answer 1

The functions setModel() and setCompleter() are void, return no value.

You can write like this:

    AraKey = ['a','ab','abc']
    ModAra = QtGui.QStringListModel()
    ModAra.setStringList(AraKey)
    ComAra = QtGui.QCompleter()
    ComAra.setModel(ModAra)
    self.LineEditAra.setCompleter(ComAra)

I have tried this, and it really works.

Answer 2

i found it .. it must pass a list to SearchBar function not a dict .. so this works ..

    # first make an empty lists 
    self.AraList = [] 
    self.GerList = []
    for raw in cors.fetchall():
        self.AraList.append(raw[0]) # put all data in one list
        self.GerList.append(raw[1]) # " "
    self.SearchBar(self.AraList,self.GerList) # passing the lists to SearchBar Function 

def SearchBar(self,keys,values): 
    print(keys) #make sure its returns one big list , Lets try the keys first 
    ModAra = QtGui.QStringListModel()
    ModAra.setStringList(keys)
    ComAra = QtGui.QCompleter()
    ComAra.setModel(ModAra)
    self.LineEditAra.setCompleter(ComAra)
     # It worked just fine
