python - __init__() 获得意外的关键字参数 'wellness'

Question

虽然标题说问题是“健康”，但事实是它在表格上随机选择一个项目并说这就是问题。

surveys.views.py

from django.shortcuts import render

def storeBloodData(request):
    if request.method == 'POST':
        form = SurveyForm(request.POST)

        if(form.is_valid()):
            cd = form.cleaned_data
            bd = SurveyForm (user=cd['user'],
                            timestamp=cd['timestamp'],
                            glucose=cd['glucose'],
                            wellness=cd['wellness'],
                            weight=cd['weight'],
                            foodGroups=cd['foodGroups'],
                            )
            bd.save()
            print("Saved weather record...")
        else:
            return render(request,
                          'bdata_form.html',{'form':form})

    print("should be calling status...")
    return render(request, 'welcome.html',{'term':"Saved data to     d/base..."})

        ('V','Vegetables'),

    class Meta:

                )

surveys.models.py

from django.db import models
from userprofile.models import UserProfile
from django.conf import settings

from django.contrib.auth.models import User




# Create your models here.

FOOD_CHOICE = {
        ('D','Diary'),
        ('F','Fruit'),
        ('G','Grains'),
        ('M','Meats'),
        ('V','Vegetables'),
        ('S','Sweets'),
    }


NUM_CHOICE = {
        ('1','1'),
        ('2','2'),
        ('3','3'),
        ('4','4'),
        ('5','5'),
        ('6','6'),
        ('7','7'),
        ('8','8'),
        ('9','9'),
        ('10','10'),
}

class Survey(models.Model):
    user = models.ForeignKey(User, related_name='Survey.user')
    glucose = models.DecimalField(max_digits=3, decimal_places=0)
    timestamp = models.DateTimeField('date published', default='1990-08-26')
    weight = models.DecimalField(max_digits=5, decimal_places=2)
    foodGroups = models.CharField(max_length=1)
    wellness = models.CharField(max_length=2, choices=NUM_CHOICE, default="1")

    def __str__(self):
        return self.user

更多信息因此它正确加载表单(并且我能够从管理端添加调查)，但每当我尝试从网站端添加它时，它都会抛出错误。

Answer 1

您正在尝试在 is_valid block 内实例化 SurveyForm，而不是调查。

但实际上你不应该尝试这样做，并且你不需要从 clean_data 设置所有这些字段:使用 ModelForm 的全部意义在于你可以只执行 form.save() 它会为您创建并保存一个模型实例。
