Question

我试图使用Django将数据输入到Mysql数据库。用户通过addSubscriber.html页面输入所需数据以保存在数据库中，但输入的数据不会保存在数据库中。每当我检查Mysql表（在本例中为'Subscribers'表）时，该表为空。我应该安装mysql-connecter吗？

以下是我的文件： views.py

from django.shortcuts import render, redirect
from django.contrib.auth.decorators import login_required
from django.views import generic
from .models import Subscribers
from .forms import addSubsForm



@login_required
def dashboard(request):
    user = request.user
    context = {'user': user}
    template = 'dashboard.html'
    return render(request, template, context)



@login_required
def addSubscriber(request):
    template = 'addSubscriber.html'
    if request.method == 'POST':
            form = addSubsForm(request.POST)
            if form.is_valid():
                name = form.cleaned_data['name']
                area = form.cleaned_data['area']
                phoneNumber = form.cleaned_data['phoneNumber']
                installationCost = form.cleaned_data['installationCost']
                billNumber = form.cleaned_data['billNumber']
                print name
                Subs = Subscribers.objects.create(name=name, area=area, phoneNumber=phoneNumber, installationCost=installationCost, billNumber=billNumber)
                Subs.save()
                return redirect('report')

    else:
            form = addSubsForm()

    return render(request, template, {'form': form})




@login_required
def report(request):
    context = locals()
    template = 'report.html'
    return render(request, template, context)

models.py

from __future__ import unicode_literals
from django.db import models


class Subscribers(models.Model):
    name = models.CharField(max_length=120)
    area = models.CharField(max_length=30)
    phoneNumber = models.CharField(max_length=10)
    installationCost = models.CharField(max_length=10)
    billNumber = models.CharField(max_length=100, unique=True)

addSubscriber.html

{%extends 'base.html'%}
{% load staticfiles %}
{% load crispy_forms_tags %}

{% block content %}



<div class="row">
    <div class="col-xs-7">

{% if form %}
<br>


      <form class="POST" action="." method="post">
          {% csrf_token %}

         {{ form|crispy }}
            <input type="submit" value="submit form" class="btn btn-primary"/>



      </form>

{% endif %}
    </div>

</div>
{% endblock %}

urls.py

from dashboard import views as dashboard_views
from profiles import views as profiles_views

from django.conf import settings
from django.conf.urls import url, include
from django.conf.urls.static import static
from django.contrib import admin


urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', profiles_views.home, name='homepage'),
    url(r'^contact/$', profiles_views.contact, name='contact'),
    url(r'^dashboard/$', dashboard_views.dashboard, name='dashboard'),
    url(r'^dashboard/addSubscriber/$', dashboard_views.addSubscriber, name='addSubscriber'),
    url(r'^dashboard/userDetail/$', dashboard_views.userDetail, name='userDetail'),
    url(r'^dashboard/report/$', dashboard_views.report, name='report'),


    url(r'^account/', include('allauth.urls')),

]

# this statement says that: if in the settings file, DEBUG is true than use this static URL
if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Answer 1

由于您使用的是两个数据库，因此要保存实体，您应通过指定

指定要保存的数据库

void displaySpace(int wordLength, string userWord, bool correctGuess, char guessChar, char remainingLetters[26])

根据Django documentation：

如果未指定using，则save（）方法将保存到路由器分配的默认数据库。

Answer 2

你在使用表单时不需要视图中的所有额外内容，为什么要使用create以及save ??

只需在form.is_valid

中试一试

       if form.is_valid():
            f = form.save(commit=False)
            f.save(using='db2')
            return redirect('report')

Django save（）方法不会将数据插入我的Mysql数据库
