Question

我有一个表单正在更新文本但不更新数据库中的复选框。复选框是数据库中的布尔模型（postgres），其中f为false且t为true。我已经查看了其他一些教程，并尝试使用多项选择但没有取得多大成功。

我提前道歉，因为我在django自学，这是我第一个令人遗憾的应用程序。

这是forms.py模块

from django import forms

from .model import parcels

class tableedit(forms.ModelForm):
        class Meta:
                model = parcels
                fields = [
                        "some_number",
                        "boolean_checkbox_1",
                        "boolean_checkbox_2"

                ]

这是model.py中的模型

from django.db import models
from django.contrib.postgres.fields import ArrayField
from django.core.urlresolvers import reverse


class TableName(models.Model):
        name = 'table_name'
        verbose_name = 'table_name'
        some_number = models.CharField('some_number', max_length=30)
        boolean_checkbox_1 = models.BooleanField('boolean_checkbox_1 ', max_length =1)
        boolean_checkbox_2 = models.BooleanField('boolean_checkbox_2', max_length = 1)
        # Returns the string representation of the model.
        def __str__(self):              # __unicode__ on Python 2
                return self.name

        def get_absolute_url(self):
                return reverse("table_edit:view", kwargs={"id": self.id})
        class Meta:
                managed = True
                db_table = 'table'

这是我的views.py

from django.shortcuts import render, redirect
from django.http import HttpResponse
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from django.views.generic import UpdateView,View
from django.contrib import auth

from django.views.decorators.csrf import csrf_protect
from model import tableedit
from django.contrib.auth.decorators import login_required
from django import forms
import simplejson
from forms import tableedit

@login_required
@csrf_protect
def table_edit(request, p_id = None):
        data = parcels.objects.get(id = p_id)
        form = tableedit(request.POST or None, instance = data)


        if form.is_valid():
                instance = form.save(commit = False)
                instance.save()
                return HttpResponseRedirect(instance.get_absolute_url())

        context = {
                "some_number" : data.some_number,
                "boolean_checkbox_1" : data.boolean_checkbox_1,
                "boolean_checkbox_2" : data.boolean_checkbox_2,
                "form":form}

        return render(request, "static/table_edit.html", context)

以下是table_edit.html文件

中的表单

{% if next %}
   <input type = "hidden" name="next" value= {% url 'table.view' table.id %} \>
   {% endif %}
    {{ form.as_p }}


<form action=next  method="post">{% csrf_token %}

  <input type="submit" value="Update Item" />
</form>

Answer 1

您的<md-icon [mdTooltip]="connectStr">{{icon}}</md-icon>不在您的html {{ form.as_p }}标记内。任何数据都不可能从该表单发送到服务器。
