我确信我非常密集,但花了几天时间试图解决我做错了什么。
我有
我正在使用Bootstrap 3,我直接编码而不是使用bootstrap-toolkit
Bootstrap在我的所有页面上渲染都很好,表单字段也是如此,但按钮不会出现。
我的HTML如下:
{% extends 'base.html' %}
{% load crispy_forms_tags %}
<html>
<title>Add Guest</title>
<div class='container'>
{% block col1 %}
<div class='row'>
<div class="span3">
{% endblock %}
{% block col2 %}
<div class="span9">
<ul>
{% crispy form %}
</ul>
</div><!--/span9-->
{% endblock %}
</div><!--row-->
</div><!--/container-->
</html>
如果我将crispy标签更改为{%crispy MyForm MyForm.helper%},我会得到'VariableDoesNotExist at'以及连续的许多(真实)语言。如上所示,表单字段显示但不显示按钮。
我的forms.py看起来像这样:
from django.forms import ModelForm
from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Fieldset, ButtonHolder, Submit
from .models import Author
class NewAuthorForm(forms.ModelForm):
class Meta:
model = Author
# If you pass FormHelper constructor a form instance
# It builds a default layout with all its fields
helper = FormHelper()
helper.form_method = 'post'
helper.add_input(Submit('save', 'save', css_class = 'btn-primary'))
我知道在进口方面存在一些冗余,但这不是问题所在。
最后,我的base.html是:
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap 101 Template</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- Bootstrap -->
<link href="{{ STATIC_URL }}css/bootstrap.min.css" rel="stylesheet">

<body>
<div class='container'>
{% block col1 %}
<div class='row'>
<div class="span3">

{% block col2 %}
<div class="span9">
</div><!--/span9-->
{% endblock %}
</div><!--row-->
</div><!--/container-->

<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="{{ STATIC_URL }}js/bootstrap.min.js"></script>
</body>
</html>
我将crispy表单模板放在我的templates文件夹中,该文件夹与manage.py处于同一级别。正如我所说的,所有的bootstrap渲染都很好。
我很难过。任何想法都感激不尽

我完全不知道为什么,但以某种方式删除
from __future__ import absolute_import
从视图中为我解决了问题,现在我的按钮出现了。
P.S发现这个问题,谷歌搜索解决方案,并决定注册并希望帮助下一个解决这个问题:)。

这是一篇很老的帖子,但如果我在搜索时就这么做了,那么其他人可能会这样做。
我使用的是Django 1.11.9和django-crispy-forms 1.7.0。您已经走上了正确的轨道,实际上您想要添加“提交”#39;该类的 init 按钮,而不是Meta。
见下文:
from django.forms import ModelForm
from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Fieldset, ButtonHolder, Submit
from .models import Author
class NewAuthorForm(forms.ModelForm):
class Meta:
model = Author
def __init__(self, *args, **kwargs):
super(NewAuthorForm, self).__init__(*args, **kwargs)
# If you pass FormHelper constructor a form instance
# It builds a default layout with all its fields
self.helper = FormHelper()
self.helper.form_method = 'post'
self.helper.add_input(Submit('save', 'save', css_class = 'btn-primary'))
