Run Selenium tests via Jenkins on Docker Django app
I would like to run Selenium integration tests on a Development server. Our App is Django app and it is deployed via Jenkins and Docker. We know how to write and run Selenium tests localy We know how to run tests with Jenkins and present Cobertura and Junit reports The problem we have is: In order for Selenium tests (apart from unit tests) the server needs to run So we can't run tests before we build docker image How to run tests inside docker images (this could be potentially achieved via script called inside Dockerfile...) BUT even more important: How can Jenkins get the reports from inside docker containers Whats are the best practice here. The Deployment structure: Jenkins get code from GIT Jenkins Builds docker images pass this image to the Docker registry (a private one) log in to the remote server on remote server pull the image from the registry run image on a remote server -

Django get query from queryset. Returning invalid params
When I try to get the query from django queryset, it returns parameters without quotes which makes it an invalid query to run I have a django code as follows: qs = SignalAssetWeightTs.objects.filter(data_date__range=[start_date, end_date]) When I try to get the query so that I can query it using pyodbc (I found django's query taking 5 seconds vs pyodbc taking <1 for 50k+ rows), I try to get the query like this: str(qs.query) However, for the parameters it returns without quotes for example the query returned is SELECT * FROM [mm_signal_asset_weight_ts] WHERE [mm_signal_asset_weight_ts].[data_date] BETWEEN 2019-01-01 00:00:00 AND 2022-01-01 00:00:00 As is evident, the quotes are missing from the 2 datetime variables so when I try to run the query using pd.read_sql_query(query, conn) then I get an error pointing to these parameters. And it's not just date param, if I try to filter using anything else, I get the same issue. I was wondering whether there's any other way to generate the query from django queryset so that I can run it using pyodbc or anything else to get a faster result. I'm using Django 3.2 and sql-server -

Show captcha after 5 incorrect login attempts with django-axes

Triggering Django thread as a background task
I have a Django app that needs to hit an API call towards an external endpoint on every 5 seconds for a check. Since I do not want to use any external tools like django-background-task, Redis, Celery, RQ or anything I built my own solution where I separated a thread for the task. This is the decorator I found here: def start_new_thread(function): def decorator(*args, **kwargs): t = Thread(target = function, args=args, kwargs=kwargs) t.daemon = True t.start() return decorator And this is how I call the function: JOB_IN_THE_QUEUE = False @start_new_thread def check_if_job_in_the_queue_and_enqueue(): """Checks if the job is already in the queue and enqueues it if needed.""" global JOB_IN_THE_QUEUE if JOB_IN_THE_QUEUE: return JOB_IN_THE_QUEUE = True success = print_something() # print_something() is just a dummy function And here is how I print indefinitely (that will later become an API call towards a 3rd party API): def print_something(): a = print_it() if not a: time.sleep(20) print_something() # print_something() is another dummy function with while True loop replacing the actual API calling Now the way I am currently calling the check_if_job_in_the_queue_and_enqueue() is at an endpoint.

Whenever one model is created or updated, I want it to insert/modify its corresponding foreign key
Whenever "Note" is created OR modified, I want it to analyze its content and decide if it needs to either create, update, or delete its corresponding entry in "Review".

Django Table Data Overlay
I am not sure if this is even possible in Django. I would like to "overlay" the data on one table with data from another based on permissions. Table 1: pk col1 col2 isEditable 0 10 4 True 1 42 1 False 2 12 2 False Table 2 would have exactly the same structure minus the isEditable column. Any attempt to write data to a row where isEditable=False will be redirected to Table 2. I am calling this data overlay, but is there a proper term for doing this and is it possible to do in Django? If so what are the best practices for doing this? I am thinking of something involving signals, but I am very new to this part of Django. If it helps the back end database is MySQL V8.0. -

Django -- Checking input type, display error message if wrong
I'm new to learning Django/Python and hoping for some assistance. This is for an assignment and I'm stumped on the last part. We need to take input from the user (name as string; weight, height inches, and height feet as ints) and calculate the bmi, displaying {{name}}'s bmi is {{bmi}} I have that part working fine, but the second part of what I have to do is check that the input is valid, that is not a string where it should be an int, and not a negative number. I am supposed to put this into the class. I was reading about is_valid() but I haven't used that yet and am not entirely sure how to do it. I am guessing it will have to be an if else statement. views.py class Home(View): def get(self, request): return render(request, 'home.html') def post(self, request): n = str(request.POST["name"]) w = int(request.POST["weight"]) hi = int(request.POST["heightinches"]) hf = int(request.POST["heightfeet"]) h = (hf*12) + hi bmi = (703*w) / (h*h) return render(request, 'response.html',{"name":n,"heightinches":hi,"heightfeet":hf,"weight":w,"height":h,"bmi":bmi} home.html {% load static %} <html> <head><title>Home</title></head> <body> <h1>Hello Repl.it</h1> <form action="" method="post"> {% csrf_token %} name: <input type="text" name="name" id="name"/> <br> weight: <input type="text" name="weight" id="weight"/> pounds<br> height: <input type="text" name="heightinches" id="heightinches"/> … -
Django API Framework for POST not working?
I have the following code: models.py class DeviceDetail(models.Model): SUBNET_CHOICES = ( ('16','16'), ('17', '17'), ('18','18'), ('19','19'), ('20','20'), ('21', '21'), ('22', '22'), ('23', '23'), ('24', '24'), ('25', '25'), ('26', '26'), ('27', '27'), ('28', '28'), ('29', '29'), ('30', '30'), ) DEV_MODS =( ('Catalyst 9606R', 'Catalyst 9606R'), ('C9300L-48T-4X', 'C9300L-48T-4X') ) mgt_interface = models.CharField(max_length=50) subnetmask = models.CharField(max_length=2, choices = SUBNET_CHOICES) ssh_id = models.CharField(max_length=50) ssh_pwd = models.CharField(max_length=50) enable_secret = models.CharField(max_length=50) dev_mod=models.CharField(max_length=50, choices = DEV_MODS) ##device_model replacement DD2DKEY = models.ForeignKey(Device, on_delete=models.CASCADE) ##The key to link up the tables def __str__(self): return self.hostname serializers.py class DeviceDetailSerializers(serializers.ModelSerializer): class Meta: model = DeviceDetail fields = ['mgt_interface', 'subnetmask', 'ssh_id', 'ssh_pwd', 'enable_secret', 'dev_mod'] views.py @api_view(['PUT']) def update_device(request, pk=None): if pk != None: devicedetail = DeviceDetail.objects.filter(DD2DKEY=pk) devdserializer = DeviceDetailSerializers(devicedetail, data = request.data) if devdserializer.is_valid(): devdserializer.save() results = { "device_details" : devdserializer.data, } return Response(results, status=status.HTTP_201_CREATED) return Response(devdserializer.errors, status=status.HTTP_400_BAD_REQUEST) The code seems correct to me but whenever i tried to use Postman to do the PUT, i get error of 500. I dont understand why is this happening. For the code, I am using https://www.youtube.com/watch?v=B65zbFro2pU to guide me on how to code as I am new to this framework. Can anyone advise me on what to do to solve this error? Thank you … -

What to include for Djoser to accept my requests?
I used DRF and Djoser for my authentication in React SPA. My question is why does it says forbidden and CSRF verification failed. what should I include to my request to grant access to my django server. export const addDummy = (data) => apiCallBegan({ url: '/product/dummy/', method: 'post', data: data, onSuccess: dummyAddedSuccess.type, onError: dummyAddedFailed.type, }); Is there a header that I should put or something? Please I'm new to djoser, django and drf.
