python - 具有自定义模板的 Django formtools

Question

我有以下自定义向导

<div class="container">
    <div id="smartwizard">
        <ul>
            <li><a href="#step-1">Engagement Setup<br /><small>Basic info</small></a></li>
            <li><a href="#step-2">File Upload<br /><small>Upload files</small></a></li>
            <li><a href="#step-3">Business Rules<br /><small>rules</small></a></li>
            <li><a href="#step-4">Documentation<br /><small>documentation</small></a></li>
        </ul>
        <div>
            <div id="step-1" class="">
                <div id="form-step-0" role="form" data-toggle="validator">
                    <div class="form-group">
                        <label for="text">Code <span class="tx-danger">*</span></label>
                        <input type="text" class="form-control" name="code" id="code" placeholder="Write your code" required>
                        <div class="help-block with-errors"></div>
                    </div>
                </div>
                <hr />
            </div>
....
        </div>
    </div>
    <br />
</div>

我已经设置了 django 表单

class PageOne(forms.Form):
    ibs_code = forms.CharField(max_length=100)
    engagement_name  = forms.CharField(max_length=100)
    engagement_manager = forms.CharField(max_length=100)
    engagement_partner = forms.CharField(max_length=100)
    solution =  forms.CharField(label='What solution would you like to use?', widget=forms.Select(choices=FRUIT_CHOICES))

当然还有观点..

class TestWizard(SessionWizardView):
    file_storage = FileSystemStorage(
        location=os.path.join(settings.MEDIA_ROOT, 'temp_uploads'))


    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.is_done = False

    def get_template_names(self):
        if self.is_done:
            # return [self.templates['done']]
            return [TEMPLATES['done']]
        else:
            return [TEMPLATES[self.steps.current]]
     .....
     ......

现在我想在表单中使用自定义模板。意思是，我想用 form-group 等以 html/style 的方式生成表单字段。我怎样才能实现这个目标？

我尝试了 documentation但它们不是自定义模板的任何来源

更新#1:仅做这样的事情是不够的

 <div id="form-step-0" role="form">
     <div class="form-group">
        {% if wizard.form.forms %}
            {{wizard.form.management_form }}
            {% for form in wizard.form.forms %}
                {{form}}
            {% endfor %}
        {% else %}
            {{ wizard.form }}
        {% endif %}
     </div>
 </div>

我需要它看起来就像我放在一起的 html

Answer 1

首先，您可以指定用于表单字段的类，例如:

class PageOne(forms.Form):
    ibs_code = forms.CharField(
        max_length=100, 
        widget=forms.TextInput(
            attrs={'class' : 'YourClassName'}
        )
    )

其次，您可以根据需要将各个字段放入模板中

<div class="container">
    <div id="smartwizard">
        <ul>
            <li><a href="#step-1">Engagement Setup<br /><small>Basic info</small></a></li>
            <li><a href="#step-2">File Upload<br /><small>Upload files</small></a></li>
            <li><a href="#step-3">Business Rules<br /><small>rules</small></a></li>
            <li><a href="#step-4">Documentation<br /><small>documentation</small></a></li>
        </ul>
        <form>
            {{ wizard.form.management_form }}
            {% csrf_token %}

        <div>
            <div id="step-1" class="">
                <div id="form-step-0" role="form" data-toggle="validator">
                    <div class="form-group">
                        <label for="text">Code <span class="tx-danger">*</span></label>
                        {{ form.ibs_code }}
                        {{ form.ibs_code.errors }}
                    </div>
                </div>
                <hr />
            </div>
....

       </div>
       </form>


    </div>
    <br />
</div>
