Django: Problem with Adding Editing and Deleting Functionality in Django Form
I am learning Django by building an application, called TravelBuddies. It will allow travelers to plan their trip and keep associated travel items (such as bookings, tickets, copy of passport, insurance information, etc), as well as create alerts for daily activities. The application will also able to update local information such as weather or daily news to the traveler. Travelers can also share the travel information with someone or have someone to collaborate with them to plan for the trip. I have created a form that enables the users to add their trip information, like trip name, planner name, co-planner, date etc. However, I can't find a proper way of allowing them to edit and delete the forms. I have seen some videos. But they are not using TemplateView like me. So, I am a bit confused. Here are my codes in forms.py file under addtrip folder: from django import forms from django.contrib.auth.models import User from django.forms import ModelForm from trips.models import Trip class TripForm(ModelForm): class Meta: model = Trip fields = ['trip_name', 'date', 'planner_name', 'add_coplanner', 'trip_description'] class UserForm(forms.ModelForm): password = forms.CharField(widget=forms.PasswordInput) class Meta: model = User fields = ['username', 'email', 'password'] Here are my codes in views.py file under … -
Python 3 Django 3.0 Running but not listening or opening port
I am using PyCharm and an instance running in AWS for remote debugging. When I start debugging the server starts and continues to run.

Hitting 500 error on django with debug=False even with ALLOWED_HOSTS=["*"]
I am getting 500 errors on every page I try to go with. The only thing that i'm changing is DEBUG to False.

Following field gets updated whenever model_obj.save() happens. modified_at = models.DateTimeField(auto_now=True, db_index=True) However, it is not updated when doing MyModel.objects.filter(id=model_obj.id).update(**kwargs) Is there a way to somehow enforce updating modified_at? -
Is Django REST framework suppose to be public?
I recently found some security holes in my university website. Among other issues was that, a page for viewing and managing api requests, using Django REST framework was found to be public. There were option to generate manage oauth tokens, and different things like that. I am planning to report the issues together soon. Is this actually a bug or is it suppose to be public? If it is a bug, what are the possible consequences? Is it to be taken seriously? -

django-cacheops... what is the "ops"?
I've searched, but I can't find anything that explains this. I know I'm risking a downvote here, but what is meant by "ops" with django-cacheops? https://github.com/Suor/django-cacheops I would think it's just a name, but sentences such as ...Here you can specify which ops should be cached... and ...You can pass any subset of this ops to... and ...with non-empty ops is... make me think I should know what 'ops' is... But the context clues aren't helping, and after reading the documentation and searching the internets, I feel like I'm missing something very obvious, and that I'm not going to get the full benefit of this tool... -

Invoke function after all methods Django Rest Framework ModelViewSet
I would like to invoke a function after all methods in a ModelViewSet. The function itself will be used as an external event log. So the response from the views would not be modified.

Add fields to a form with django at application level
I am using django and I need to use a form that is dynamic, that at the application level the user can add fields to the form. For example, I have a beer and I want to add features, which function would allow me to place an 'add' button and a new input will appear to put a new feature to the beer unlimited times, thus being able to add the number of features inputs that you want . If anyone knows the name of a function that allows me to do it or a link to the solution! Thanks in advance. I read a little about the FormSet and the Management Form but I really didn't understand exactly how to use it! If I could add a brief example it would be helpful -

How to delete 0001_initial.py in Django? Django migrations are not working
I am using Django 2.2 with Python 3.7 on Windows 10. I created a project and then an app. The models.py was populated by using INSPECTDB for an existing Postgres database. I removed the line 'managed = False' from each class. I created the initial makemigrations and did the migrate. There are app migration files, 0001_initial.py and init.py I had to make changes, adding more classes, in the models.py file. Then I ran the makemigration and migrate on the app. Now I get a message '.errors.DuplicateTable: relation "INT_ORG" already exists.' Throws an exception. I tried to use 'python manage.py makemigrations' and got the message that there were no changes detected. I tried to use 'python manage.py migrate --fake-initial'. This Errored with duplicate table already exists No luck. I'm failing badly here. And while working yesterday, somehow - don't know how, another migration file shows up called '0002_auto_20191212_1137.py' The '0002_auto_20191212_1137.py' migration file has all my changes in it. But it is not being migrated either when I try to makemigrations and migrate. I need to go back to a point I can understand and not loose everything. A co-worker had a similar problem and they just started a new project and … -

Django rest framework - Optimizng serialization of nested related field
Given the following models: class Model_A: ... class Model_B: ... class Model_C: model_a = ForeignKey(Model_A, related_name='c_items') model_b = ForeignKey(Model_B) ... And the following model serializers setup: class Model_A_Serializer: class Model_C_Serializer: class Meta: model = Model_C fields = ( 'model_b', ... ) c_items = Model_C_Serializer(many=True) class Meta: model = Model_A fields = ( 'c_items', ... ) And a basic vieweset: class Model_A_Viewset: model = Model_A queryset = model.objects.all() serializer_class = Model_A_Serializer ... When the user POST's the following JSON payload to create an instance of Model_A along with instances of Model_C: { 'c_items': [ { 'model_b': 1 }, { 'model_b': 2 }, { 'model_b': 3 } ] } Note: Model_B instances with IDs 1, 2, and 3 already exist, but no Model_A and no Model_C instances exist in the above example. Then I noticed that django seems to execute the following queries when serializing the incoming data: SELECT ... FROM Model_B WHERE id = 1; SELECT ... FROM Model_B WHERE id = 2; SELECT ... FROM Model_B WHERE id = 3; This seems unnecessary to me as a single SELECT ... FROM Model_B WHERE id IN (1,2,3) would do the job. How do I go about optimizng this? I have tried … -
