扩展用户拥有许多药物

Question

我想像这样将许多药物保存到配置文件中。

型号.py

class Profile(AbstractUser):

class Medications(models.Model):
user = models.ForeignKey(Profile,related_name='user',on_delete=models.CASCADE)
name = models.CharField(default='',max_length=100)
amount = models.IntegerField()
per_time = models.IntegerField()
time_choices = (('other', 'Other'),('Post meal', 'Post meal'),('Breakfast' ,'Breakfast'))
choice = models.CharField(max_length=10, choices=time_choices,default='others')

forms.py

class MedicationForm(forms.ModelForm):
name = forms.CharField(max_length=100, required=True, help_text='Required.')
amount = forms.IntegerField( required=True, help_text='Required.')
class Meta:
model = Medications
fields = ('name','amount','per_time','choice')

现在在这里，我想与请求用户创建一个药物。我使用了if-form.is_valid((：form.save((，它只在/addMed中给出IntegrityError/NOT NULL约束失败：pages_medications.user_id需要来自请求。user

@login_required
@require_http_methods(["POST"])
def addMed(request):
print('Adding med')
print(request.user)
print(request.POST)
med = MedicationForm(request.POST or None,)
print(med)
return redirect('medications')

这就产生了

Adding med
user
<QueryDict: {'csrfmiddlewaretoken': ['-'], 'name': ['Tylenol'], 'amount': ['1'], 'per_time': ['1'], 'choice': ['other'], 'medicationForm': ['Upload']}>

然后在这里列出所有药物。

views.py

@login_required
def medications(request):
context={}  
context['nmenu'] = 'medications'
context['medicationForm'] = MedicationForm()
return render(request, 'home.html', context)

您应该将登录的用户分配给Medications对象：

@login_required
@require_http_methods(['POST'])
def addMed(request):
med = MedicationForm(request.POST, request.FILES)
med.instance.user = request.user
med.save()
return redirect('medications')
