Question

让这段代码将csv导入我的Django DB。这是我的模型数据库，在保存时我得到了错误。这是创建错误的行

 23764,"HUA FU","vessel","DPRK4",-0- ,-0- ,-0- ,"10,030",-0- ,"Panama",-0- ,"Vessel Registration Identification IMO 9020003; Linked To: CHANG AN SHIPPING & TECHNOLOGY."

在我的数据库中，该列为vessel_dwt = models.IntegerField(blank=True, null=True)

我应该如何将列放入数据库？作为浮点数还是字符串？这是我的导入代码。

import csv, sys, os

# project_dir = "/Users/cohen/my-python-project/venv/ofac/ofac_project/ofac_sdn/import_save/"
# project_dir = "/Users/Dropbox/ofac_project/ofac_sdn/import_save/"
project_dir = "/Users/Dropbox/ofac_project"
sys.path.append(project_dir)
os.environ['DJANGO_SETTINGS_MODULE']='ofac.settings'

import django
django.setup()

from ofac_sdn.models import Ofac_Sdn
from ofac_sdn.models import Ofac_Add
from ofac_sdn.models import Ofac_Alt
from ofac_sdn.models import Ofac_Sdn_Comments


file    = 'new_sdn.csv'
file1   = 'new_add.csv'
file2   ='new_alt.csv'
file3   ='new_sdn_comments.csv'

data = csv.reader(open(file),delimiter=",")
for row in data:
    if row[0] !="Number":
        post = Ofac_Sdn()
        post.number = row[0]
        post.name = row[1]
        post.b_i=row[2]
        post.programe=row[3]
        post.more_info=row[4]
        post.vessel_call_sign=row[5]
        post.vessel_type=row[6]
        post.vessel_dwt=row[7]
        post.tonnage=row[8]
        post.vessel_flag=row[9]
        post.vessel_owner=row[10]
        post.dob_aka=row[11]
        post.save()

在导入之前，我将替换奇数字符：

import requests
import csv, os, sys
newstring = "null"
newinteger = str(0)
newstring1= "null"
newstring2= "null"
newstring3= "null"
with open('sdn.csv', 'r') as file1, open('new_sdn.csv', 'w') as file2:
    reader = csv.reader(file1, delimiter=',')
    writer = csv.writer(file2, delimiter=',')
    for row in reader:
        replaced7 = row[7].replace('-0-', newinteger)
        row[7] = replaced7           
        writer.writerow(row)

谢谢！

Answer 1

我已经从田里删除了所有的昏迷。

我已添加此代码：

replaced7b=row[7].replace(',', '')
        row[7]=replaced7b
        replaced8 = row[8].replace('-0-', newinteger)
        row[8]=replaced8
        replaced8b=row[8].replace(',', '')
        row[8]=replaced8b

Answer 2

你可以使用这样一个班轮。

post.vessel_dwt=int(''.join(row[7].split(',')))

Django错误：ValueError：基数为10的int（）的无效文字：'10,030'
