Question

我有Django表格，但是当它们为空时它们不会变成红色或显示错误（它们是必需的）。我有点确定要做什么。

views.py

def lOut(request):
    if request.user.is_authenticated():
        context = {
            "extendVar":"baseLoggedIn.html",
        }
    if request.user.is_authenticated()==False:
        form=registerForm(request.POST or None) 
        if form.is_valid():
            email = form.cleaned_data['email']
            print ("yup")
        elif form.is_valid()==False:
            print ("nup")
            print (form.errors)
        print("eh")     
        context= {
            "extendVar":"baseNotLoggedIn.html",
            "form":form,
        }

base.html文件：

{% extends extendVar %}

{% block title %}
    {{ block.super }} lagro
{% endblock %}

{% block fname %}
    {{ form.fname }}
{% endblock %}

{% block lname %}
    {{ form.lname }}
{% endblock %}

{% block email %}
    {{ form.email }}
{% endblock %}

{% block emailConfirm %}
    {{ form.emailConfirm }}
{% endblock %}

{% block password %}
    {{ form.password }}
{% endblock %}

baseNotLoggedIn.html

<form method="post" action="{% url 'try3' %}">
  {% csrf_token %}
  <div class="row row-buffer">
      <div class="col-sm-6" style="padding-right:5px;" >
        {% block fname %} {% endblock %}                
        <!-- <input class="form-control" placeholder="First Name" id="fname"> -->
      </div>

      <div class="col-sm-6" style="padding-left:5px;">
        {% block lname %} {% endblock %}
        <!-- <input class="form-control" placeholder="Last Name" id="lname"> -->
      </div>

    </div>
    <div class="row row-buffer">
      <div class="col-sm-12 form-group-lg">
        {% block email %} {% endblock %}
        <!-- <input class="form-control" placeholder="Email" id="email"> -->

      </div>
    </div>

    <div class="row row-buffer">
      <div class="col-sm-12 form-group-lg">
        {% block emailConfirm %} {% endblock %}
      </div>
    </div>

    <div class="row row-buffer">
      <div class="col-sm-12 form-group-lg">
        {% block password %} {% endblock %}                
        <!-- <input type="password" class="form-control" placeholder="Password" id="password"> -->
      </div>
    </div>

    <div class="row row-buffer">
      <div class="col-sm-12 form-group-lg">
        <button type = "submit" class="btn btn-success btn-lg" style="outline-width:0;">Submit</button>
      </div>
    </div>
  </form>

forms.py

class registerForm(forms.Form):
    fname = forms.CharField(max_length=256, label="", required=True, widget=forms.TextInput(attrs={'class': 'form-control','placeholder': 'First Name',}))
    lname = forms.CharField(max_length=256, label="", required=True, widget=forms.TextInput(attrs={'class': 'form-control','placeholder': 'Last Name',}))
    email = forms.EmailField(max_length=256, label="", required=True, widget=forms.EmailInput(attrs={'class': 'form-control','placeholder': 'Email',}))
    emailConfirm = forms.EmailField(max_length=256, label="", required=True, widget=forms.EmailInput(attrs={'class': 'form-control','placeholder': 'Confirm email',}))
    password = forms.CharField(max_length=256, label="", required=True, widget=forms.PasswordInput(attrs={'class': 'form-control','placeholder': 'Password',}))

Answer 1

它没有显示，因为您没有在模板中呈现任何错误。引自django doc：

您需要确保我们处理每个字段的任何错误整个表格的任何错误。注意{{form.non_field_errors}} 在表单的顶部和模板查找每个错误领域。使用{{form.name_of_field.errors}}显示表单列表错误。

阅读django doc，了解如何在模板中呈现表单错误。

Answer 2

将forms.py更改为此。

class registerForm(forms.Form):
    fname = forms.CharField(max_length=256, label="", required=True, widget=forms.TextInput(attrs={'class': 'form-control','placeholder': 'First Name','required': True}))
    lname = forms.CharField(max_length=256, label="", required=True, widget=forms.TextInput(attrs={'class': 'form-control','placeholder': 'Last Name','required': True}))
    email = forms.EmailField(max_length=256, label="", required=True, widget=forms.EmailInput(attrs={'class': 'form-control','placeholder': 'Email','required': True}))
    emailConfirm = forms.EmailField(max_length=256, label="", required=True, widget=forms.EmailInput(attrs={'class': 'form-control','placeholder': 'Confirm email','required': True}))
    password = forms.CharField(max_length=256, label="", required=True, widget=forms.PasswordInput(attrs={'class': 'form-control','placeholder': 'Password','required': True}))

P.S。添加＆＃39;必需＆＃39;：对你的attrs dict来说是真的。

看到这一点。

>>> name = forms.TextInput(attrs={'required': True})
>>> name.render('name', 'A name')
'<input name="name" type="text" value="A name" required />'
