React+ServiceWorker and Django admin panel caching problem
I am working on a larger project than usually and it is being hosted on AWS using dockers and all the magical stuff. We have backend that is available under /admin route and while the browser recieves a request I'd like to skip to loadBalancer instead of giving the request in to serviceWorker to decide if it should serve cached /admin or not. In my modules I've got: NavigationRoute.mjs constructor(handler, { whitelist = [/./], blacklist = [/^\/admin\/.*/]} = {}) so I was quite sure it should work, but that's just a local change. How should I go about to get these changes pushed? Sometimes I can see people waving eject command but I don't want to configure the project myself. Maybe someone here had a chance to work with Django+React+ServiceWorker like myself and would like to share hers/his approach. Current status: App is being hosted on https://staging.nextgloc.com/ and doesn't get /admin if you don't clear cache (therefore allowing me to access it until it's cached again). -
form not display on html, django
I tried to make a blog that allows user posts, store the posts in the db along with the posted date time and the person who posted it. My problem is that I somehow cannot load the {{form}} to my UI, which makes my form invalid and I just don't know why it doesn't show up the input text box. I'm not sure if I need a get_post function, but I'll just put it in views.py. (I havnt write the html of that part yet. Just need to see the form first.)

Refactor try and Except codeblocks in Python
Currently my app is working with several external APIs, and those functions can raise some kind of error, and I would like to be aware of all kind of situations and don't crash my app. In the following piece of code you can see my function, using slack api (it's just an example, not real example), and you can see how I'm creating a space giving the name and the emails. That function can returns several errors, like APIerror, TypeError... etc etc Also you can see, all the functions in that file, can raise some errors so it is using try and except and try to don't break our app. In the except part, I don't want to do anything special, just return the error or I don't know, raise an custom error. In the future would be cool if I can enqueue that task if something goes wrong. slack_client.py def create_space(): try: slack_api.create.space(spaceName='space name', email=emails) except (...): ... def delete_space(): try: slack_api.delete.space(spaceId=space_id) except (...): ...

Django referencing foreignkeys on updates
I just started recently learning Django but stumbled upon the situation that I use update_or_create Demo_user_sessions.objects.update_or_create(session=params['session'][0], defaults=item) however the object item contains one key that is being used as ForeignKey. Currently, I define the key with item[entry] = Demo_user_sessions.objects.get(session=params['session'][0]) This however doesnt work. So my question how do I have to change the create_update call or the key so that the reference to the foreign key works? -
Retrieving all the Json records from a Django Rest Framework endpoint using Jquery
I'm using Jquery to get JSON data from a DRF API endpoint. Here is how i fetch the data: $.getJSON('http://127.0.0.1:8000/tst/', function(data) { console.log(data) }); This is what i'll get in my console: count: 742, which is true, since there are 742 records in total; the problem is that the console.log() statement will give me only the first 50 records; same for any other operation: i'm only able to work with the first 50 records retrieved from the endpoint. Here is what my data looks like: "results": [ { "item": "First", "id": "1847" .. }, { "item": "Second", "id": "4442" ..}, { "item": "Third", "id": "3847" ..}, // 739 more records here ] And here is how i created the endpoint: view class tstList(generics.ListCreateAPIView): queryset = tst.objects.all() serializer_class = tstSerializer filter_backends = [DjangoFilterBackend] filterset_fields = ('item', 'id' ) And here is my serializer: class tstSerializer(serializers.ModelSerializer): class Meta: model = tst fields = ('item', 'id') def create(self, validated_data): return tst.objects.create(**validated_data) What is happening here? Is the problem on my backend, or is it with Jquery? Any advice is appreciated -

Is this DJango code snippet correctly retrieving data from the database?
I am having some issues with DJango. Currently, our website does not display all the options in the drop-down menu. It just shows one element that is not appropriate functionality trying to fix My suspicion is that the JQuery is not correctly retrieving the data. I was taking a look at the HTML file, and at line 42 is where the DJango code loops through the entity books, in order to retrieve the book id attribute that we want to display in the drop-down menu. I am new to DJango, and I am not sure if those lines(42-45) are correctly executing. Thank you very much. HTML file containing lines 42-45 -

How to connect Django database to Sql server?
I hope you are doing well. I have recently started learning django and it has been going great. However, there is a problem I am facing. I am having difficulties to connect it to the Sql database. I have read some of the previous threads and most of the people were suggesting to use "pyodbc" as a library. However, it appears that this library is not compatible with the new versions of python and django. After filling in the database information, I am getting the following error: django.core.exceptions.ImproperlyConfigured: Django 3.0.3 is not supported. I have tried a combination of different python, django, pyodbc, django-pyodbc-azure versions but none of them seems to be working. Moreover, when I run the code in the terminal it works and connect to the database. Hence, I wanted to know whether there is a workaround this problem? Or am I missing something obvious? DATABASES = { 'default': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'xxxxx', 'HOST': '111.111.1.111', 'USER': 'abc', 'PASSWORD': "bca", 'OPTIONS': { 'driver': 'ODBC Driver 17 for SQL Server', #'driver': 'SQL Server', 'unicode_results': True, }, }, } Your help would be greatly appreciated! -

Django Generic Foreign key filter by object nested field

Example objects = GenericModelDemo.filter(childmodel__user__email='email@example.com') I searched for how to achieve this but all answers are filtering based on the object_id like content_type = ContentType.objects.get_for_model(ChildModel) GenericModelDemo.objects.filter(content_type=content_type, object_id=child.id) But, this does not resolves my query. How can I filter using the generic foreign key fields instead of just id? -

How to update objects from a model that has a OneToOneField with the User model in Django?

I'm creating a Django site, on a certain template i added an Ajax form and i would like to add an autocomplete feature, in order to make navigation easier. My main problem is that the data i should search is a JSON array of objects, while most of the solutions i found work with normal arrays. Here is what i have now: <script> $(document).ready(function(){ // Defining the local dataset $.getJSON('http://127.0.0.1:8000/myapi/', function(data) { console.log(data) //Autocomplete }); }); </script> <input type="text" id='firstfield' name='input_val'> This is what the data looks like, it's around 700 records; here are the first three: "results": [ { "item": "First", "id": "1847", }, { "item": "Second", "id": "4442", }, { "item": "Third", "id": "3847", }] I need this to be as fast as possible. Is there a JQuery/Ajax native solution for this? Or is there a specific library to do this? Any advice or solution is appreciated, thanks in advance! -

Optimise Django query
I have a model in my Django project class AmazonSearchFrequency(models.Model): keyword_name = models.CharField(max_length=500) frequency = models.PositiveIntegerField(default=0) I am storing around 2 milion data in this table but whenever I do a search query like AmazonSearchFrequency.objects.filter(keyword_name=keyword) take a long time to execute the query. Is that anyway in Django where I can optimize this query.
