TemplateDoesNotExist at /users/register/bootstrap5/uni_form.html

问题描述 投票：0回答：6

我正在为我的 django 项目构建一个注册表格，为了设计它的样式，我使用了脆皮表格。但是，当我运行我的服务器并转到我的注册页面时，我看到了这个错误：

    Internal Server Error: /users/register/
Traceback (most recent call last):

    raise TemplateDoesNotExist(template_name, chain=chain)
django.template.exceptions.TemplateDoesNotExist: bootstrap5/uni_form.html

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\core\handlers\exception.py", line 47, in inner

    raise new from exc
django.template.exceptions.TemplateDoesNotExist: bootstrap5/uni_form.html

这看起来不像我通常看到的

TemplateDoesNotExistError
。我认为这是我的 crispy 表单中的错误，因为如果我删除表单中的 crispy 模板标签，一切正常。

这是我的注册模板：

{% extends 'base.html' %}
{% load crispy_forms_tags %}

{% block title %}Register{% endblock %}

{% block content %}
<h1>Sign up for a new account</h1>
<hr>
<form action="" method="post">
    {% csrf_token %}
    {{ form|crispy }}
    <button type="submit" class="btn btn-sm btn-primary">Register</button>
</form>
<p>
    Already have an account?
    <a href="#">Log in</a>
</p>
{% endblock %}

以防万一，这是我的视图函数：

def register(request):
    form = RegistrationForm()

    if request.method == 'POST':
        form = RegistrationForm(data=request.POST)
        if form.is_valid():
            form.save()
            return HttpResponse("Successfully Registered!!!")

    context = {
        'form':form,
    }
    return render(request, 'users/register.html',context)

我在我的 settings.py 中指定了 CRISPY_TEMPLATE_PACK 并且还在我的 INSTALLED_APPS 中添加了 crispy_forms。我哪里错了？

编辑：

所以我对这个主题做了更多的研究，这个错误可能是因为 crispy forms 还不支持 bootstrap 5。因此，通过将我的 CRISPY_TEMPLATE_PACK 中的 bootstrap5 更改为 bootstrap4，错误就解决了

python django django-crispy-forms

我也遇到了这个问题，但是 crispy-form 已经支持 boostrap 5。在他们的 github 页面中是这样指示的

$ pip install django-crispy-forms

$ pip install crispy-bootstrap5

在 settings.py 中

INSTALLED_APPS = [
 ...,
'crispy_forms',
'crispy_bootstrap5',  # Forgetting this was probably your error
 ]

然后在页面底部的settings.py

CRISPY_ALLOWED_TEMPLATE_PACKS = "bootstrap5"
CRISPY_TEMPLATE_PACK = "bootstrap5"

这对我解决了 TemplateDoesNotExist 错误。无需降级到 bootstrap4

基于最新的crispy form doc，似乎没有内置

bootstrap5
。你确定你用的是
bootstrap5
？

目前只有bootstrap、bootstrap3、bootstrap4、uni-form

如果你甚至看到

bootstrap5
文件夹，你可以看看你的文件结构。

正如您所说，您已经安装了 crispy_forms 并添加到 settings.py 中的 installed_apps 文件然后下一步是使用以下代码： pip install crispy-bootstrap5 - 在你的命令行

然后在您的 settings.py 文件中做一些更改，如下所示：

CRISPY_ALLOWED_TEMPLATE_PACKS = "bootstrap5"

CRISPY_TEMPLATE_PACK = "bootstrap5"

bootstrap 5 模板包将是一个单独的包。 PyPI 上有一个非常早期的版本，这里是 GitHub 链接。

从 django-crispy-forms 2.0 开始，模板包现在位于单独的包中。

您需要

pip install crispy-bootstrap4
并将
crispy_bootstrap4
添加到您的INSTALLED_APPS列表中。

This is a confilict of bootstrap5 you are using but try to load django crispy form in 4 to solve this by 

#pip install crispy-bootstrap5

*settings.py*
INSTALLED_APPS = [
 ...,
'crispy_forms',
'crispy_bootstrap5',  # Forgetting this was probably your error
 ]
CRISPY_ALLOWED_TEMPLATE_PACKS = "bootstrap5"
CRISPY_TEMPLATE_PACK = "bootstrap5"
