django脆皮表单覆盖布局对象模板被忽略 [英] django crispy forms overriding layout objects templates ignored

问题描述

我应用了此
因此我有

I applied this thus I have

self.helper.layout = Layout(
    Field(
    'title', template="mytemplate.html"
    ) ,

模板未呈现
helper.field_template在以下代码中为None ：

（C：\myapp\lib\ crispy_forms\templatetags\crispy_forms_filters.py）：

(C:\myapp\lib\crispy_forms\templatetags\crispy_forms_filters.py):

@register.filter(name='as_crispy_field')
def as_crispy_field(field, template_pack=TEMPLATE_PACK, label_class="", field_class=""):
    """
    Renders a form field like a django-crispy-forms field::

        {% load crispy_forms_tags %}
        {{ form.field|as_crispy_field }}

    or::

        {{ form.field|as_crispy_field:"bootstrap" }}
    """
    if not isinstance(field, forms.BoundField) and settings.DEBUG:
        raise CrispyError('|as_crispy_field got passed an invalid or inexistent field')

    attributes = {
        'field': field,
        'form_show_errors': True,
        'form_show_labels': True,
        'label_class': label_class,
        'field_class': field_class,
    }
    helper = getattr(field.form, 'helper', None)

    template_path = None
    if helper is not None:
        attributes.update(helper.get_attributes(template_pack))
        template_path = helper.field_template
    if not template_path:
        template_path = '%s/field.html' % template_pack
    template = get_template(template_path)

    c = Context(attributes).flatten()
    return template.render(c)

如果我在调试时将helper.field_name修改为mytemplate.html，我会看到它成功呈现。

if I modify helper.field_name on debug to mytemplate.html, I see it is rendered with success.

问题是什么是我的模板被忽略的原因？

Question is what could be reason that my template is ignored?

重要说明，我的表单扩展了：

class RoomForm(ModelForm)

其中 ModelForm 为此处

在我的表单中，我用以下方式呈现：

In my form I render with:

  {{ form.title | as_crispy_field }}

我的观点的相关部分是：

and relevant part of my view is:

  form = RoomForm(None, prefix="submit-room" )                   
  return render(request, 'edit_room.html', { 'form': form })

最终将mytemplate.html复制为无处不在：
C：\myapp\lib\crispy_forms\模板bootstrap4 和 C：\myapp\templates\mytemplate.html

finally mytemplate.html is, copied "everywhere": C:\myapp\lib\crispy_forms\templates\bootstrap4 and C:\myapp\templates\mytemplate.html

{% load custom_tags %}
<div>tutu</div>
<div>{{field}}</div> 

推荐答案

我不想将问题目的改变很多到目前为止我可以用输入来回答它：

I don't want to change question purpose to much that I can answer it with the inputs so far I got:

self.helper.layout = Layout(
    Field(
    'title', template="mytemplate.html"
    ) 

成功设置单个字段模板，但 as_crispy_field 不在乎，但它采用表单模板值。

Successfully sets individual fields template but as_crispy_field does not care it but it takes form template value instead.

如果我渲染

{% crispy form %}
