python - Django/Python:表单数据未存储在数据库中

Django 1.8 / Python 3.4

我想通过名为“ add”的Django视图从html表单添加数据到我的数据库。但是，由于某种原因，这种情况不会发生，并且我无法弄清楚出了什么问题。大概是视图代码中的错误，但是我到底需要更改什么呢？

models.py

from django.db import models
from model_utils import Choices

class Entry(models.Model):
    user = models.CharField(max_length=50)
    title = models.CharField(max_length=200)
    description = models.TextField()
    due_date = models.DateField('Date')
    due_time = models.TimeField('Time')
    STATUS = Choices('Open', 'Done')
    status = models.CharField(choices=STATUS, default=STATUS.Open, max_length=4)

def __unicode__(self):
    return u"%s %s %s %s %s" % (self.user, self.title, self.description, self.expiry, self.status)

def expiry(self):
    return u"%s %s" % (self.due_date, self.due_time)

我的add.html中有趣的部分

    <td><input type="text" name="title"></td>
    <td><input type="text" name="description"></td>
    <td><input type="text" name="due_date"></td>
    <td><input type="text" name="due_time"></td>
    <td>
        <select name="status" size="1" selected value="Open">
            <option>Open</option>
            <option>Done</option>
        </select>
    </td>

表格

from django import forms
from django.forms.widgets import TextInput

class EntryForm(forms.Form):
    title = forms.CharField(max_length=200)
    description = forms.widgets.TextInput()
    due_date = forms.DateField()
    due_time = forms.TimeField()
    status = forms.ChoiceField(choices=[(x, x) for x in range(1, 2)])

以及我的views.py中的相关视图

from django import forms
from django.shortcuts import render
from django.shortcuts import redirect
from website.list.forms import EntryForm

def add(request):
    if request.method == "POST":
        form = EntryForm(request.POST)
        if form.is_valid():
            new_entry = form.save()
            new_entry.save()
            return redirect('website')
    else:
        form = EntryForm()
    return render(request,'add.html', {'form': form})

任何帮助表示赞赏！



[编辑]

因此，这就是我的add.html现在的样子：

<form action="." method="post">
{% csrf_token %}
{{ form }}
    <br><input type="submit" value="Send"/>
    <br><br><a href="{% url 'overview' %}">Cancel</a>
</form>

再次稍微修改一下views.py：

from django import forms
from django.shortcuts import render
from django.shortcuts import redirect
from www.todolist.forms import EntryForm
from django.contrib.auth.models import User

def add(request):
    if request.method == "POST":
        form = EntryForm(request.POST)
        if form.is_valid())
            form.save()
            return redirect('website')
    else:
        form = EntryForm()
    return render(request,'add.html', {'form': form})

最佳答案

弄清楚了 ...
这是forms.py的外观，以便save（）函数在视图中起作用：

class EntryForm(forms.ModelForm):
CHOICES = (
    ('1', 'Open'),
    ('2', 'Done'),
)
title = forms.CharField(max_length=200)
description = forms.CharField(widget=forms.Textarea)
due_date = forms.DateField()
due_time = forms.TimeField()
status = forms.ChoiceField(choices=CHOICES)

class Meta:
    model = Entry
    fields = '__all__'

需要注意的重要事项是“ ModelForm”，而不仅仅是“ Form”和类Meta信息。
