Question

我有一个模特＆＃39;合作伙伴＆＃39;与“产品”的一对多关系。当我添加＆＃39;产品＆＃39; formset我打破了与关系有关的事情 - html仍显示例如<h3>Products</h3>，并且提交按钮仍然存在，但不再有任何表格框。因此看起来表单正在加载，但有些东西可能不会被传递。任何帮助将不胜感激。以下是我的代码。

我的forms.py

<div class="container">
    <div class='col-sm-6'>
    <h1>Preview</h1>
    <hr/>
        <div class='content-preview'>
            <h3 id='preview-name'></h3>
            <p id='preview-mission'></p>
            <p id='preview-vision'></p>
            <p id='preview-website-link'></p>
            <p id='preview-fb-link'></p>
            <p id='preview-twitter-link'></p>
            <p id='preview-ig-link'></p>
        </div>
    </div>
    <div class='col-sm-6'>
        <h1>Form</h1>
        <hr/>
        <form method='POST' action='' enctype='multipart/form-data'>{% csrf_token %}
            {{ partnerForm|crispy }}
            {{ formset.management_form }}
            <br>
            <h3>Products</h3>
            {% for form in formset %}
                {{ form|crispy }}
            {% endfor %}
            <input type='submit' class='btn btn-default' value='Create Partner' />
        </form>
    </div>
</div>

我的form.html

class PartnerForm(forms.ModelForm):
    mission = forms.CharField(widget=PagedownWidget(show_preview=False))
    vision = forms.CharField(widget=PagedownWidget(show_preview=False))
    # publish = forms.DateField(widget=forms.SelectDateWidget)
    class Meta:
        model = Partner
        fields = [
            "name",
            "logo",
            "banner_image",
            "mission",
            "vision",
            "website_link",
            "store_link",
            "fb_link",
            "twitter_link",
            "ig_link",
        ]

class ProductForm(forms.ModelForm):
    image = forms.ImageField(label='Image')
    class Meta:
        model = Product
        fields = [
            "name",
            "link",
            "description",
            "price",
            "image",
        ]

如果我还能提供其他任何内容，请告诉我。

Answer 1

您的partner_create和partner_update观看次数都会呈现partner_form.html模板。

但是，partnerForm视图中的上下文中未包含formset或partner_update。而是包含form，您不在模板中的任何位置使用。

我的表单字段不再出现在更新页面上？
