Question

我是django的新手，我有以下问题。当我使用createCompany.html登录并创建公司时，公司将在数据库中创建，但其用户＆＃39;属性保持空白。 user属性应该是登录并创建公司的用户。您认为我的代码有什么问题？

models.py

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

class Company(models.Model):
    name = models.CharField(primary_key = True, max_length = 100)
    city = models.CharField(max_length = 30, null = True)
    user = models.OneToOneField(User, on_delete=models.SET_NULL, null = True)

    yontemler =(('3CNC', '3 eksen CNC'),('5CNC', '5 eksen CNC'),)

    imalatyontem = models.CharField(max_length=30, choices=yontemler, null=True, verbose_name = 'İmalat Yöntemleri')

    industries =(('Imalat', 'İmalat'),('Kimya', 'Kimya'),('Hammadde', 'Hammadde'),)

    industry = models.CharField(max_length=20, choices=industries, null=True, help_text='Sektörünüzü Seçin')

    @classmethod
    def create(cls, name, city, user, imalatyontem, industry):
        company = cls(name=name, city=city, user=user, imalatyontem=imalatyontem, industry=industry)
        return company

    def get_absolute_url(self):
         return models.reverse('company-detail', args=[str(self.id)])

    def __str__(self):
        return self.name

views.py

from .forms import CompanyCreationForm

def createCompany(request):
    if request.method == 'POST':
        form = CompanyCreationForm(request.POST)
        if form.is_valid():
            form.save()
            name = form.cleaned_data.get('name')
            city = form.cleaned_data.get('city')
            user = request.user
            imalatyontem = form.cleaned_data.get('imalatyontem')
            industry = form.cleaned_data.get('industry')
            Company.create(name, city, user, imalatyontem, industry)
            return redirect('index')
    else:
        form = CompanyCreationForm()
    return render(request, 'createCompany.html', {'form': form})

forms.py

from django import forms
from .models import Company

class CompanyCreationForm(forms.ModelForm):    
    class Meta:
        model = Company
        fields = ['name', 'city', 'imalatyontem', 'industry']

createCompany.html

{% extends "base_generic.html" %}

{% block content %}

<form action="/createCompany/" method="post">
    {% csrf_token %}
    {% for field in form %}
        <fieldset class="control-group">
            <label class="control-label" for="id_{{ field.name }}">{{ field.label }}</label>
            <div class="controls">
                {{ field }}

            </div>
        </fieldset>
    {% endfor %}
    <input type="submit" value="Submit" />
</form>

你的create班级方法毫无意义;你应该删除它。它不会保存对象，然后扔掉它。

在添加用户之前，创建实例的工作实际上是由form.save完成的。所以你应该使用标准模式：

   if form.is_valid():
        obj = form.save(commit=False)
        obj.user = request.user
        obj.save()
        return redirect('index')

Django：用户没有被分配到模型的实例
