イムValidationErrorをして要求された形式にフォーマットを変更することについては移動する方法が正直すぎてわかりません。私は、現在のデータを読んでいる方法がある：
sample_fields = [
'street', 'diameter', 'thickness', 'installation_date', 'mh_to_mh', 'shot_and_sec', 'other',
'flexural_strength_and_modulus_test', 'wall_thickness_test', 'tensile_strength_test',
'APS_water_tightness_test', 'FTIR_test', 'other_test',
]
...
for num, line in lines:
try:
# creates a dictionary of all the field names for sample fields
# and the values in the csv file
sample_dict = {k: line[k] for k in sample_fields}
# creates a dictionary of all the field names for parameter_fields
# and the values in the csv file
parameter_dict = {k: line[k] for k in parameter_fields}
# this is working because when the except is commented out the
# csv will create the contracts, but the samples are not added
# if the contract in the csv is not already in the contracts list then
if line['contract_no'] not in contracts:
#create the contract with the company, contract_no and rec_required
contract = Contract(client=company,
contract_no=line['contract_no'],
reconciliation_required=True if line['reconciliation_required'] == '1' else False)
contract.save()
contracts[line['contract_no']] = contract
#errors_found.append('Here')
# using the Sample function from models.py pass it the
