我应该如何连接字典的user_id&模型的user_id? [英] How should I connect dictionary's user_id & model's user_id?

问题描述

我想解析excel&制作字典并连接具有相同user_id字典的model(User).现在字典是

I wanna parse excel& make dictionary and connect the model(User) which has same user_id of dictionary. Now dictionary is

dict_data = {'user_id': 1,'nationarity': America, 'dormitory':'A', 'group': 3}

views.py中的模型是

Models in views.py is

user = User(user_id=rows[1],name_id=rows[2],age=rows[3],employee=rows[4])

如果我想将字典的数据添加到模型中，我应该写为

If I wanna add dictionary's data to model,I should write like

for data in dict_data:
    User(**data)

但是我应该如何连接字典的user_id&模特的一个?我该怎么写?

but how should I connect dictionary's user_id& models' one?What should I write it?

现在我写得像

#coding:utf-8
from django.shortcuts import render
import xlrd
from app.models import User
book3 = xlrd.open_workbook('./data/XXX.xlsx')
sheet3 = book3.sheet_by_index(0)
headers = sheet3.row_values(0)

large_item = None
dicts = {}
for row_index in range(sheet3.nrows):
    rows3 = sheet3.row_values(row_index)
    large_item = rows3[1] or large_item

    # Create dict with headers and row values
    row_data = {}
    for idx_col, value in enumerate(rows3):
        header_value = headers[idx_col]
        # Avoid to add empty column. A column in your example
        if header_value:
            row_data[headers[idx_col]] = value
            # Add row_data to your data_dict with
    dicts[row_index] = row_data
    for data in dicts:
        user1 = User.objects.filer(user_id = data['user_id']).exists()
        if user1:
            user1.__dict__.update(**dicts)
            user1.save()

当我运行这段代码时，

AttributeError: 'Manager' object has no attribute 'filer'
user1 = User.objects.filer(user_id = data['user_id']).exists()

我该如何解决?

推荐答案

dict_data 是dict，不应像列表一样对其进行迭代.我猜你的 dict_data 是字典的列表，所以:

dict_data you posted is a dict,you shouldn't iterate it like a list. I guess your dict_data is a list of dict, so:

for data in dict_datas:
    user = User.objects.get(user_id=data['user_id'])
    user.name_id = data['**']
    ...
    user.save()

首先，在xecel& dict中使用 user_id 提取用户对象，然后更改值并保存.

First, fetch the user object with user_id in your xecel&dict, then change the value, and save it.
