Question

我创建了一个表单窗口小部件，它自动在表单顶部添加一个添加新记录部分，我不想在那里。谁能告诉我如何禁用它？我只是想显示变量而不是添加形式。

forms.py

class TemplateVariablesWidget(forms.Widget):
    template_name = 'sites/config_variables.html'

    def render(self, name, value, attrs=None):
        sc_vars = ConfigVariables.objects.filter(type='Showroom')
        wc_vars = ConfigVariables.objects.filter(type='Major Site')
        context = {
            'SConfigVariables' : sc_vars,
            'WConfigVariables' : wc_vars,
        }
        return mark_safe(render_to_string(self.template_name, context))


class VariableForm(forms.ModelForm):
    variables = forms.CharField(widget=TemplateVariablesWidget, required=False)

    class Meta:
        model = ConfigVariables
        fields = "__all__"

admin.py

class ConfigTemplateAdmin(admin.ModelAdmin):  
    list_display = ('device_name', 'date_modified')
    def change_view(self, request, object_id, form_url='', extra_context=None):
        extra_context = extra_context or {}
        #extra_context['include_template'] = '/path/to/template.html'
        extra_context['include_form'] = VariableForm
        return super(ConfigTemplateAdmin, self).change_view(
            request, object_id, form_url, extra_context=extra_context,
        )

change_view.html

{% block extra_content %}
    {% if include_template %}
        {% include include_template %}
    {% endif %}
    {% if include_form %}
    <form method="POST" class="post-form">
        {% csrf_token %}
        {{ include_form.as_p }}
    </form>
    {% endif %}
{% endblock %}

如果我在您的模板中了解您的意图，您希望包含模板或包含该表单。如果是这样的话：

{% if include_template %}
    {% include include_template %}
{% elif include_form %}
    <form method="POST" class="post-form">
        {% csrf_token %}
        {{ include_form.as_p }}
    </form>
{% endif %}

另一种可能性是，您不希望在extra_context['include_form'] = VariableForm课程中ConfigTemplateAdmin，并且可以在表格中添加新的变量来创建不同的视图（或当前视图中的方法）！ / p>

管理好了解决这个问题。我添加了一个包含数据选项，并按照以下内容将其发送到模板：

def change_view(self, request, object_id, form_url='', extra_context=None):
    from sites.models import ConfigVariables
    config_variables = ConfigVariables.objects.all()
    extra_context = extra_context or {}
    extra_context['include_data'] = config_variables
    extra_context['include_template'] = 'admin/config_variables.html'
    #extra_context['include_form'] = VariableForm
    return super(ConfigTemplateAdmin, self).change_view(
        request, object_id, form_url, extra_context=extra_context,
    )

然后在模板中

{% for d in include_data %}
