Django bulk create with self reference foreign key

Replacing template with another with Django
I am trying to find a way to replace only a section of a web page with another template based on the change of a drop down. Also I don't want the rest of the page to reload. I'm using jquery to call the function when the drop down is changed so that's not an issue. The closest way I have is to use ajax replace the contents of a div with something else but when I try to pass a django tag that would refer to another html template, the string "{% include 'upgrading_template.html' %}" prints on the page rather than reading it as an include statement. I have also tried methods like replaceWith() but I get the same result. $.ajax({ type: 'GET', url: {% url 'sw_upgrade' %}, data: parameters, success: function (response) { document.getElementById('upgrade_template').innerHTML = "{% include 'upgrading_template.html' %}"; } }) -
Use of same serializer class for post and get request in Django rest framework
I have a Student model which has some fields. What I need is I want to create a student object using post API with certain fields and however needs to show some other fields while doing get request. For eg: My model: class Students(models.Model): name = models.CharField(max_length=255,blank=True) email = models.EmailField(unique=True) phone = models.CharField(max_length=16) address = models.CharField(max_length=255,blank=True) roll = models.IntegerField() subject = models.CharField(max_length=255,blank=True) college_name = models.CharField(max_length=255,blank=True) Now my serializer will look like this. class StudentSerializer(serializers.ModelSerializer): class Meta: model = Student fields = ['id','email','name','phone','roll','subject','college_name', 'address'] Suppose, I have a view that handles both post and get api (probably using APIView), then what I need is, to create a student object I only need name, phone and email. So for post api call, I only need three fields whereas while calling the get api I only need to display the fields name, roll, subject, and college_name not others. In this situation, how can I handle using the same serializer class?? -

However, when I try to open it online it crashes with the following error: > 2021-10-29T13:16:54.435118+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of > launch > 2021-10-29T13:16:56.287092+00:00 heroku[web.1]: Stopping process with SIGKILL > 2021-10-29T13:16:56.458881+00:00 heroku[web.1]: Process exited with status 137 > 2021-10-29T13:16:56.499621+00:00 heroku[web.1]: State changed from starting to crashed > 2021-10-29T13:17:13.107001+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" > host=shrouded-bastion-04661.herokuapp.com > request_id=81455b66-dab8-4b20-9c69-91b73739a09a fwd="71.231.14.146" > dyno= connect= service= status=503 bytes= protocol=https > 2021-10-29T13:17:13.558163+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" > host=shrouded-bastion-04661.herokuapp.com > request_id=c6b25451-528e-4bed-a415-f35b0bcb739f fwd="71.231.14.146" > dyno= connect= service= status=503 bytes= protocol=https I'm not really sure what to make of it but when I ran the app locally it said: 2021-10-29T13:15:49.232426+00:00 heroku[web.1]: State changed from crashed to starting 2021-10-29T13:15:54.128556+00:00 heroku[web.1]: Starting process with command `python manage.py runserver 0.0.0.0:5000` 2021-10-29T13:15:55.975995+00:00 app[web.1]: Watching for file changes with StatReloader 2021-10-29T13:15:55.976241+00:00 app[web.1]: Performing system checks... 2021-10-29T13:15:55.976241+00:00 app[web.1]: 2021-10-29T13:15:56.168039+00:00 app[web.1]: System check identified no issues (0 silenced). 2021-10-29T13:15:56.434599+00:00 app[web.1]: 2021-10-29T13:15:56.434616+00:00 app[web.1]: You have 20 unapplied migration(s).
