如何在Django中不使用自动模型表单从文本框获取数据？

Question

我有一件很简单的事情想做，但不知道为什么还没找到解决办法。

我有一个HTML表单：

<form id="user_form" method="POST" action="/ProjectName/home/">

    {% csrf_token %}

    <div class="registerLabel">
        Full name:
    </div>
    <div class="registerTextLabel">
        <input type="text" id="registerFullName" class="registerTextDetails">
    </div>
    <div class="registerLabel">
        Username:
    </div>
    <div class="registerTextLabel">
        <input type="text" id="registerUsername" class="registerTextDetails">
    </div>

    <div id="registerButtonDiv">
        <button class="registerButtons" id="cancelRegisterButton">Cancel</button>
        <button type="submit" class="registerButtons" id="submitRegistration">Register</button>
    </div>
</form>

我想要的就是在填写完这个表单并提交后，把所有的文本框里的值拿出来，放到我的数据库里。

我的数据库模型是这样实现的：

class User(models.Model):
    username = models.CharField(max_length=200)
    password = models.CharField(max_length=200)
    ...
    def __unicode__(self):
        return self.username

这是视图的代码：

def register(request):
    context = RequestContext(request)
    registed = False
    if request.method == 'POST':
        form = User(data = request.POST)
        username = request.POST.get('registerUsername')
        password = request.POST.get('registerPass')
        user = form.save()
        username = User.username
        password = User.password
        u = User(username,password,...)
        u.save()
        registered = True
        else:
            form = User()

        return render_to_response('ProjectName/home.html', {'user_form':User}, context)

我不想使用Django那种自动生成表单的方式，它是根据模型生成表单的。

这是我的html文件：

{% block content %}
    <div class="container">
        <h6 class="dress"><a href="{% url 'home' %}">Home</a> <i> </i> Register </h6>
    </div>
    <div class="back">
        <h2>PRODUCTS</h2>
    </div>
     <div class="container">
        <div class="register">
        <h3>PERSONAL INFORMATION</h3>
              <form method='POST' action=''>{% csrf_token %}
                    <div class="mation">
                    <div>
                        <span>User Name</span>
                        <input id="id_username" maxlength="150" name="username" type="text" required />
                        <span class="helptext">Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only.</span></p>
                    </div>
                     <div>
                         <span>Email Address</span>
                         <input id="id_email" maxlength="254" name="email" type="text" />
                         </div>
                         <div>
                            <span>Password</span>
                                <input id="id_password1" name="password1" type="password" required />
                    </div>
                             <div>
                            <span>Confirm Password</span>
                                <input id="id_password2" name="password2" type="password" required />
                    </div>
                     </div>
                     <input type="submit" value="Register">
                </form>


           </div>
            </div>
{% endblock %}

现在你可以看到我的注册表单：

class RegistrationForm(forms.ModelForm):
    password1 = forms.CharField(label="Password", widget=forms.PasswordInput())
    password2 = forms.CharField(label="Confirm Password", widget=forms.PasswordInput())

    class Meta:
        model = User
        fields = ['username', 'email']

    def clean_password2(self):
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")

        try:
            if ((password1 and password2) and (password1 != password2)):
                raise forms.ValidationError("Password Do not Match")
        except:
            pass
        return password2

    def save(self, commit=True):
        user = super(RegistrationForm, self).save(commit=False)
        user.set_password(self.cleaned_data['password1'])
        if commit:
            user.save()
        return user

就这样，我在Django中使用了自定义文本框。

这段代码是不是应该这样写：

username = User.username
password = User.password

而不是：

User.username = username
User.password = password

Answer 3

你忘了在表单里定义名字了。这对获取POST数据很重要。

<form .........>
   {{error}}<br/><br/>
<div class="registerLabel">Username:</div>
<div class="registerTextLabel">
    <input type="text" id="registerUsername" name="registerUsername" class="registerTextDetails">
</div>

<div class="registerLabel" id="registerLabelPass">Password:</div>
<div class="registerTextLabel">
    <input type="password" id="registerPass" name="registerPass" class="registerTextDetails">
</div>
</form>

def register(request):
    context = RequestContext(request)
    registered = False
    error = ''
    if request.method == 'POST':
        username = request.POST.get('registerUsername')
        password = request.POST.get('registerPass')

        if username and password:
            username_exist = User.objects.filter(username=username)
            if username_exist:
                error = username is already taken, try another
            else:
                User.objects.create(username=username, password=password)
                registered = True
        else:
            error = all fields are required

    return render_to_response('ProjectName/home.html', {'error':error}, context)
