My code:

I use an existing file for implemented my dataset depending to confitions, et i want to test dataset integration using ressource of my model

 def Mvmtjs(self,file, espace):

        import csv

        csvfile = open(file, 'r')
        reader = csv.reader(csvfile,delimiter=';')

        dataset = tablib.Dataset(headers=['indice', 'plt', 'ref_dossier_ath'])
       ]


        with open('tmp/edi/in/working/write_file.csv', "w+", encoding='mac_roman', newline='') as csv_file1:  


            next(reader)  # Skip header row.
            next(reader)  # Skip header row.

            for row in reader:


                if row[2] != "":

                    if espace == '1' or '2':

                    dataset.append( (
                               row[2],
                               row[0], 
                               row[2], 
                                  ))

        result = MasterDossierResource.import_data(dataset, dry_run=True, raise_errors=True)

thank you in advance

Answer 1

It was an error around my resources... I had forgotten to initialize my resources:

dossier_ressource = MasterdossierRessource()
result = dossier_ressource.import_data(dataset, dry_run=True, raise_errors=True)
