Django 不自動填充當前用戶外鍵

Question

我正在從前端向我的數據庫中插入條目，但當前登錄的用戶外鍵沒有填充。 它輸入為 null。

這是我的 model：

from django.db import models
from django.contrib.auth.models import User

# Create your models here.

class WordsAndPhrases (models.Model):
    word_or_phrase = models.CharField(max_length=20000)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    added_by = models.ForeignKey(User, null=True, on_delete=models.DO_NOTHING)
 
    def __str__(self):
        return self.word_or_phrase

這是我的views.py 代碼片段。

def upload(request):
    if request.method == 'POST':
        wordOrPhrase = request.POST['word-or-phrase']
        currentUser = request.user
        print(currentUser)
        newEntry = WordsAndPhrases(word_or_phrase = wordOrPhrase)
        addedBy = WordsAndPhrases(added_by = currentUser)
        newEntry.save()

    return render(request, 'display_words_phrases_app/upload.html')

提前致謝。

Answer 1

您需要在 model 中定義一個 id 鍵

id = models.AutoField(primary_key=True, )

Answer 2

您正在創建兩個條目對象。 當你創建一個新的 object 時，你應該像這樣插入word_or_phrase和added_by ：

def upload(request):
if request.method == 'POST':
    wordOrPhrase = request.POST['word-or-phrase']
    currentUser = request.user
    print(currentUser)
    newEntry = WordsAndPhrases(word_or_phrase = wordOrPhrase, added_by = currentUser)
    newEntry.save()

return render(request, 'display_words_phrases_app/upload.html')

您添加的addedBy沒用。
