Question

我搜索了20到30个帖子，但没有找到任何有用的内容。我是通过从视图中的HTML文件或表单中选择值来将数据存储到数据库。请告诉我如何实现这一目标。我错过了什么代码。在此先感谢您的帮助。

view.py

   def blog_list(request):
form = AttendanceForm()
if request.method == "POST":
    form1 = AttendanceForm(request.POST)
    if form1.is_valid:
        form1.save()
        return render(request, 'blog/blog_list.html',{
        'form1':form1,
        })

return render(request, 'blog/blog_list.html',{
    'form':form,
    })

my forms.py

class AttendanceForm(forms.ModelForm):
        action = forms.ModelChoiceField(queryset=Action.objects.all(), empty_label="-----------", required=True)
        employee = forms.ModelChoiceField(queryset=Employee.objects.all(), empty_label="-----------", required=True)
        class Meta:
            model = Action
            fields = ['employee','action']

我的model.py

    class Action(models.Model): 
    action_name = models.CharField(max_length = 100)

    def __str__(self):
        return self.action_name

class Employee(models.Model):
    employee_id = models.AutoField(primary_key = True)
    employee_name = models.CharField(max_length = 100)

    def __str__(self):
        return self.employee_name

class Attendance(models.Model):
    u = models.ForeignKey(Employee)
    action = models.ForeignKey(Action)
    action_time = models.DateTimeField(default=timezone.now())

Answer 1

在Python中，您需要使用括号来调用方法。

    if form.is_valid():
        form.save()

Answer 2

在Model：

中进行这些更改后，它正常工作

import urllib2
import json

API_KEY='key'

f = urllib2.urlopen('http://api.wunderground.com/api/' 
+ API_KEY + '/geolookup/conditions/q/IA/Cedar_Rapids.json')

# Saving the below variable into a .json file gives all the JSON data
# on a single line
json_string = f.read()

with open('data.json', 'w') as outfile:
    json.dump(json_string, outfile, indent=4, sort_keys=True, separators=(",", ':'))
