Question

我已将数据的文本文件制成表格，记录的数量太多，无法在数据库中一张一张地上传有什么方法可以将数据导入到我在模型

中创建的表中

Answer 1

我创建了一个简单的脚本，可能对您来说是一个开始。该脚本将读取一个csv文件并将其存储到数据库中。通过将filename.csv替换为文件位置，并将YourModel替换为它代表的实际模型，您应该能够修改它以满足您的需求。您还需要将obj.field1 = line[0]更改为彼此匹配的代表列和字段。

import csv

# Open the csv file and reads it into a two dimensional List
with open('filename.csv', 'rb') as f:
    reader = csv.reader(f)
    lines = list(reader)

# Create an empty list of objects of your model
objects = []

# Iterate each record of the csv file
for line in lines:
    # Create an empty instance of your model
    obj = YourModel()
    # Populate the fields of the model based on the record line of your file
    obj.field1 = line[0] # The first column
    obj.field2 = line[1] # The second column
    # Add the model to the list of objects
    objects.append(obj)

# Save all objects simultaniously, instead of saving for each line
YourModel.objects.bulk_create(objects)
