使用 bootstrap3 作为脆皮表单的模板包时,获取模板不存在错误



我正在为我的 django 项目使用 django-crispy-forms,并且在文档中我看到要使用 bootstrap3 功能(如水平表单),我需要通过在项目 settings.py 中添加以下行来将 bootstrap3 设置为我的脆皮模板包:

CRISPY_TEMPLATE_PACK = 'bootstrap3'

根据文档,Crispy的默认值是bootstrap v2。但是在我的设置中添加 bootstrap3 后,当我在开发机器中运行我的应用程序时,出现此错误:

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:Python27VirtualEnvsTlaloclibsite-packagesdjangotemplateloader.py in find_template, line 136
Python Executable:  C:Python27VirtualEnvsTlalocScriptspython.exe
Python Version: 2.7.7

如果我从设置中删除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,但是表单水平类在我的表单中不起作用。

这就是我的表格在 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?

事实证明,bootstrap3 模板目录在我的脆皮表单安装中不存在。

我在我的Windows系统上安装了Crispy Forms版本1.3.2。在github的项目页面中,我看到当前版本(目前为1.4.0)确实具有\crispy_forms\templates\bootstrap3目录。看起来 bootstrap3 模板包是在此版本之前引入的,旧版本没有模板包。我升级到当前版本,它现在可以工作了。

当我升级基本软件包(Django 1.11 到 DJango 3.2,Wagtail 2.0 到 Wagtail 2.16 等)时,我发生了这个错误。我通过单独安装crispy_bootstrap3并将其包含在INSTALLED_APPS中来修复它。我还必须设置 CRISPY_TEMPLATE_PACK = 'bootstrap3',这很奇怪,因为我有另一个项目使用最新版本的 Django/Wagtail/Crispy Forms,我不需要做任何这些,我一直认为 bootstrap 是默认的模板包。听起来有点生气,但如果您降级,请发表评论。

$pip install crispy-bootstrap3

INSTALLED_APPS = [
...
    'crispy_forms',
    'crispy_bootstrap3',
...
]
...
CRISPY_TEMPLATE_PACK = 'bootstrap3'
  1. settings.py文件中,包括以下内容:

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

  1. 然后,在register.html中编写以下代码:
