Django - taking values from POST request
Solution 1:
Read about request objects that your views receive: https://docs.djangoproject.com/en/dev/ref/request-response/#httprequest-objects
Also your hidden field needs a reliable name and then a value:
<input type="hidden" name="title" value="{{ source.title }}">
Then in a view:
request.POST.get("title", "")
Solution 2:
If you need to do something on the front end you can respond to the onsubmit event of your form. If you are just posting to admin/start you can access post variables in your view through the request object. request.POST which is a dictionary of post variables
