如何在 Django 中获取表单字段的 id

Question

Is there any way to get the id of a field in a template?

In the HTML I get: <input name="field_name" id="id_field_name"...

I know I can get the name with {{ field.html_name }} , but is there anything similar for getting the id?
Or can I only get it like this: id_{{ field.html_name }} ?

Answer 1

你可以得到这样的ID：

{{ field.auto_id }}

Answer 2

你也可以使用id_for_label ：

{{ field.id_for_label }}

Answer 3

This doesn't work for every form field.

For instance {{ form.address.auto_id }} works while {{ form.address.auto_name }} will not.

However you can use {{ form.address.html_name }} to get the equivalent answer.

Here are the docs

Answer 4

In Django 2 you can retrieve the ID for a specific field using {{ field.id_for_label }}

This is documented here .

Answer 5

From the documentation-

each form field has an ID attribute set to id_<field-name> , which is referenced by the accompanying label tag. This is important in ensuring that forms are accessible to assistive technology such as screen reader software. You can also customize the way in which labels and ids are generated.

So I would like to say id_field-name , you collect the field name from the model.
