how to pass tow custom attribute value from "select option" form to view in django

Issue

i have an html form inclouds select input , and the option have extra attribute value called "testvalue" , and want to pass the "testvalue" to my views, and here is my example as the following :

    <select  class="form-control select2" name="q_post_id"  >

        <option disabled selected >Select Post</option>

        {% for post in all_posts %}

            <option value="{{post.item.id}}" testvalue = "my test value" >  {{post.item.message}}</option>

        {% endfor %}

    </select>

normally in my view function i use :

    q_post_id = request.POST.get("q_post_id")

but this will give me a default value "{{post.item.id}}",

so how can i get the extra attribute in view ?

thanks.

Solution

i solve my problem by send "dictionary string" value from my html form ,
and then convert it to python dictionary in my view, and here my codes :

html form select option :

<select  class="form-control select2" name="q_post_id"  >

    <option disabled selected >Select Post</option>

    {% for post in all_posts %}

        <option value='{ "postid_key" : "{{post.item.id}}" , "key2": "value2" }'  >  {{post.item.message}}</option>

    {% endfor %}

</select>

in views.py:

import json

if request.method == "POST":
    q_post_id = request.POST.get("q_post_id")
    if  q_post_id:
        print(type(q_post_id))
        q_post_id = json.loads(q_post_id)
        print(type(q_post_id))
        print(f"your postid_key is : {q_post_id['postid_key']}")
        print(f"your key2 is : {q_post_id['key2']}")

the output :

<class 'str'>
<class 'dict'>
your postid_key is : 122431899774433
your key2 is : value2

done.
