How can I set default value to a form field and then hide it away?

Speechmatics submit a job without audio argument

When using Django's Prefetch object, it makes one query per related object
So I've been developing with Django for a while. I am familiar with prefetch_related and was noticing some strange behavior today when working with Prefetch objects. I was under the impression that a queryset executed with prefetch_related would make 2 queries, 1 for the parent objects, and another for the children filtering on the parent object ids. However, when I print the queries being executed using pretch_related with a Prefetch object, I noticed that one query was being made per related object which diminishes the desired effect of prefetch_related. Can anyone fill me in to why this is happening based on the following code and returned SQL. Schedule.objects.prefetch_related("shifts") # SQL returned [{"sql": 'SELECT "schedule"."id" FROM "schedule" LIMIT 21', "time": "0.033"}, { "sql": 'SELECT "shift"."id" FROM "shift" WHERE "shift"."shift_id" IN (1, 2) ORDER BY "shift"."order" ASC', "time": "0.062", } ] The above is what I expected Now the problem queryset Schedule.objects.prefetch_related( Prefetch( "shifts", queryset=Shift.objects.filter( state__in=[StopPointStates.COMPLETED, StopPointStates.PENDING] ) .order_by("assigned_at", "priority", "order") .only("id"), ) ).only("id") # SQL returned [{"sql": 'SELECT "schedule"."id" FROM "schedule" LIMIT 21', "time": "0.009"}, { "sql": 'SELECT "shift"."id" FROM "shift" WHERE ("shift"."state" IN (\'completed\', \'pending\') AND "shift"."shift_id" IN (1, 2)) ORDER BY "shift"."assigned_at" ASC, "shift"."priority" ASC, "shift"."order" ASC', "time": "0.015", … -
Uploading Django project to Heroku - blank page showing Internal server error
So I've deployed my first project to Heroku using PostgresQL. To my excitement, I managed to upload my files to both Github and Heroku. But to my disappointment, when I open the website, I only see a page showing "Internal Server Error". Why does this error show and how can I resolve it? I've been spending 9 month learning, HTML, CSS, Java, Python, Django, React, Bootstrap. This is the last step before I have a page online. So I appreciate all help!

gdal required on django but why?
I imported 3 tables on to my postgresql. These tables have the names of countries, regions, cities and then IP to countries. They are pretty old but very exhaustive. In my models I have not created any geo field or any point field, the latitude and longitude were expressed as float fields and I did that precisely to avoid having to install libraries. Yet, when I was writing makemigrations, I got an error that I needed to install gdal library. Reluctantly I did, but then it asked me that I needed to install GLIBCXX_3.4.30 library. It turns out they are not available for Fedora. What is this lousy break? I am using Fedora 37 and I am pretty annoyed at this, because, why would django tell me that I have to install that? Has it detected that the tables in postgresql have city names, latitude and longitudes? they are expressed as float fields in the table cells. -
