问题
I have looked around for an answer for this for a while now with no success. I basically want to get the name of a form field with the prefix included. Does anyone know how to do this?
Example:
Let's say I create a form in views.py and include a prefix like this:
myform = SomeForm(prefix="prefix")
and then pass it to my template. If I then access a form field within the template directly I by {{ myform.username }} get something like this (notice that the prefix was included):
<select id="id_prefix-username" name="prefix-username"> ...
If I however would like to manually create the form tag and just insert the name, then I don't get the prefix with it:
<input name="{{ myform.username.name }}">
will generate:
<input name="username">
Notice how it is now missing the prefix. Now, I can do it like this to achieve the same result:
<input name="{{ myform.prefix }}-{{ myform.username.name }}">
But there must be a built in way to do this?
回答1:
You can use html_name instead:
<input name="{{ myform.username.html_name }}">
That should add the prefix as needed
