PyQt5：QSqlTableModel連接QTableView和QLineEdit

所以我得到了我正在建設的項目，我有QDialog與QTableView，QPushButton和QLineEdit。PyQt5：QSqlTableModel連接QTableView和QLineEdit

我從數據庫中創建了數據模型，我創建了映射器，將數據從數據庫設置到LineEdit並將模型提供給QTableView。所以我已經嘗試並沒有成功將表連接到LineEdits。

做這樣的事情，這些「當我點擊它填補與數據LineEdit行是在該行上，並保存數據時編輯」在這裏我得到了什麼至今：

from ui_categorias import Ui_Dialog 
from PyQt5.Qt import QMessageBox, QDialog, QDataWidgetMapper 
from PyQt5.QtSql import QSqlRelationalTableModel, QSqlTableModel 

class frmCategories(QDialog, Ui_Dialog): 
    def __init__(self, parent = None, dbCon=None, strTblName=None): 
     super(frmCategories, self).__init__(parent=None) 
     self.setupUi(self) 

     #Criando o Model 
     self.model = QSqlTableModel(self,dbCon) 
     self.model.setTable(strTblName) 
     self.model.select() 

     a = self.model 
     self.mapFields() 

    def mapFields(self): 
     id, nome, descricao, comentarios,activo = range(0,5) 
     ''' 
     Esta funcao estabekece as ligacoes entre os widgets e o modelo 

     ''' 
     self.mapper = QDataWidgetMapper() 
     self.mapper.setModel(self.model) 
     self.mapper.addMapping(self.LECodigo, id) 
     self.mapper.addMapping(self.LENome, nome) 
     self.mapper.addMapping(self.PTEDescricao, descricao) 
     self.mapper.addMapping(self.PTEComentarios, comentarios) 
     self.mapper.addMapping(self.CBActivo, activo) 
     self.mapper.toFirst() 

     self.TVCategorias.setModel(self.model)

請顯示Ui_Dialog代碼。 – eyllanesc

當你問一個問題時，你必須提供一個[最小，完整和可驗證的例子]（https://stackoverflow.com/help/mcve） – eyllanesc

你去那裏剛剛編輯的ui_file – Fe3back

創建了一個可能的解決方案。

def getInfTbl(self, row = QModelIndex): #only call parameters of that kind 
    curWorkmodel = self.TVCategorias.model() #Get The current working model 
    clickedRow = row.row() # index from the item the mouse clicked #QModelIndex 
    self.mapper.setCurrentModelIndex(row) # set index of the mapper to the same as in the model 
    for i in range(0,5): #1-Codigo 2-Nome 3-Descrica 4-Comentario 5-Inativo 
     curWorkmodel.index(clickedRow,i) #the index the item correspond to
