使用 bootstrap3 作为 crispy 表单的模板包时出现 TemplateDoesNotExist 错误

Question

我正在为我的 django 项目使用 django-crispy-forms，并阅读 documentation I saw that to be able to use bootstrap3 features (like horizontal forms)，我需要通过在settings.py 我的项目：

CRISPY_TEMPLATE_PACK = 'bootstrap3'

根据文档，crispy 的默认设置是 bootstrap v2。但是在我的设置中添加 bootstrap3 之后，当我运行我的应用程序在我的开发机器上时，我得到这个错误：

TemplateDoesNotExist at /dashboard/
bootstrap3/field.html
Request Method: POST
Request URL:    http://localhost:8000/dashboard/
Django Version: 1.7.3
Exception Type: TemplateDoesNotExist
Exception Value:    
bootstrap3/field.html
Exception Location: C:\Python27\VirtualEnvs\Tlaloc\lib\site-packages\django\template\loader.py in find_template, line 136
Python Executable:  C:\Python27\VirtualEnvs\Tlaloc\Scripts\python.exe
Python Version: 2.7.7

如果我从我的设置中删除 CRISPY_TEMPLATE_PACK 行（使用默认值）或将其更改为如下所示：

CRISPY_TEMPLATE_PACK = 'bootstrap'

然后我不再收到错误消息，但是水平表单 class 在我的表单中不起作用。

这是我的表单在 forms.py

中的样子

class UserForm(forms.Form):
    user = forms.CharField(label='Account', max_length=15)
    password = forms.CharField(widget=forms.PasswordInput())

    # Crispy forms code
    def __init__(self, *args, **kwargs):
        super(UserForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.form_class = 'form-horizontal'
        self.helper.label_class = 'col-sm-2'
        self.helper.field_class = 'col-sm-10'
        self.helper.layout = Layout(
            Fieldset(
                '',
                'user',
                'password',
            ),
            Div(FormActions(
                Submit('continue', 'Continue', css_class='btn btn-primary'),
                Button('cancel', 'Cancel', css_class='btn btn-default',
                       data_dismiss='modal'),
                ),
                css_class='modal-footer'
                )
            )

这是我模板的一部分：

{% load crispy_forms_tags %}

<div class="modal fade" id="adAccountModal" tabindex="-1" role="dialog" aria-labelledby="authenticationLabel" aria-hidden="true">
            <div class="modal-dialog">
                <div class="modal-content">

                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                        <h4 class="modal-title" id="authenticationLabel">{{ config_values.environment_name }} Environment Authentication</h4>
                    </div>

                    <div class="modal-body">
                        <p>Please enter the account and password that will be used to authenticate in the selected environment.</p>
                        {% crispy user_form %}
                    </div>

                    {% comment %}
                    The footer will be added through the user_form using Crispy Forms.
                    The following code will be just left here as reference. 
                    <div class="modal-footer">
                        <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                        <button type="button" class="btn btn-primary">Continue</button>
                    </div>
                    {% endcomment %}
                </div>
            </div>
        </div>

我做错了什么？

Answer 1

原来我安装的crispy forms中不存在bootstrap3模板目录。

我的 Windows 系统上安装了 Crispy Forms 1.3.2 版。查看 github 中的项目页面，我看到当前版本（目前为 1.4.0）确实有 \crispy_forms\templates\bootstrap3 目录。看起来这个版本之前引入了 bootstrap3 模板包，旧版本没有模板包。我升级到当前版本，现在可以使用了。

Answer 2

在 settings.py 文件中，包括：

CRISPY_ALLOWED_TEMPLATE_PACKS = ('bootstrap', 'uni_form', 'bootstrap3', 'foundation-5')

然后，在register.html中写下这段代码：

<!DOCTYPE html>

<!-- {% load crispy_forms_tags %} -->
