我试着用我的Django表单为Choice Field生成帮助文本

i_agree = forms.CharField(label="", help_text="Initial to affirm that you agree to the <a href='/contract.pdf'>contract</a>.", required=True, max_length="4")

However, the raw HTML is rendered as output in the help text. How do I input HTML into the help text of a Django form field?

4 个解决方案

#1

You can use mark_safe in the model to indicate the html is safe and it should be interpreted as such:

您可以在模型中使用mark_safe来指示html是安全的，它应该被解释为：

from django.utils.safestring import mark_safe

i_agree = forms.CharField(label="", help_text=mark_safe("Initial to affirm that you agree to the <a href='/contract.pdf'>contract</a>."), required=True, max_length="4")

#2

You can alternatively mark it as safe in the template if you loop through the form yourself:

如果您自己遍历表单，也可以在模板中将其标记为安全：

{% for f in form %}
    {{f.label}}{{f}}{{f.help_text|safe}}    
{%endfor%}

That's a very simple example of doing so in the template. You would need to do more than that to make it look nice.

这是在模板中这样做的一个非常简单的例子。你需要做的不仅仅是让它看起来不错。

You can use an external file to increase maintainability and separation of concern:

您可以使用外部文件来提高可维护性和关注点分离：

1. modify yourform's __init__() method ;
2. 修改yourform的__init __（）方法;
3. after the super(MyForm, self).__init__(*args, **kwargs) ;
4. 超级之后（MyForm，self）.__ init __（* args，** kwargs）;
5. assign the result of render_to_string() to self.fields['my_field'].help_text.
6. 将render_to_string（）的结果分配给self.fields ['my_field']。help_text。

forms.py

from django.template.loader import render_to_string

来自django.template.loader导入render_to_string

class MyForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        # Only in case we build the form from an instance,
        if 'instance' in kwargs and kwargs['instance'].nature == consts.RiskNature.RPS:
            self.fields['my_field'].help_text = render_to_string('components/my-template.html')
            #                      ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ 

my-template.html

{% load i18n %}
<table class="table table-bordered">
    <tr>
        <th>{% trans 'Externe' %}</th>
    </tr>
    <tbody class="text-muted">
        <tr>
              <td>{% trans "En lien avec les relations de travail" %}</td>
          </tr>
          <tr>
              <td>{% trans "-" %}</td>
          </tr>
    </tbody>
</table>
