React i18next fails to load translation after in build
I don't know why react i18next display loading namespace fails on the debug console. I tried many suggestions without success. I'm using the react build folder inside Django project. It works fine on localhost:3000 only which is crazy but once i try to use the build folder I get the above error on the debug console i18n.js : import i18n from 'i18next'; import { initReactI18next } from 'react-i18next'; import Backend from 'i18next-http-backend'; import LanguageDetector from 'i18next-browser-languagedetector'; // don't want to use this? // have a look at the Quick start guide // for passing in lng and translations on init const Languages = ['ar', 'en', 'fr'] i18n .use(Backend) .use(LanguageDetector) .use(initReactI18next) // passes i18n down to react-i18next .init({ lng: 'en', react: { useSuspense: true, }, // the translations // (tip move them in a JSON file and import them, // or even better, manage them via a UI: https://react.i18next.com/guides/multiple-translation-files#manage-your-translations-with-a-management-gui) supported: ["en", "fr", "ar"], fallbackLng: "en", detection: { order: ['path', 'cookie', 'htmlTag', 'localStorage', 'subdomain'], caches: ['cookie'], }, debug: true, whitelist: Languages, interpolation: { escapeValue: false, // not needed for react as it escapes by default }, nsSeperator: false, keySeperator: false, backend: { loadPath: '/locales/{{lng}}/{{ns}}.json', }, }); export default i18n; index.js : import … -
Why does Django ORM do operations on my timestamp field even if I didn't setup TIME_ZONE and USE_TZ in my settings.py
Django ORM seems to be converting my timestamp in a weird way and I'm not sure why. Currently, our app doesn't have the settings TIME_ZONE and USE_TZ. There wasn't any need so far so we didn't use it. Now, I'm trying to show some specific timestamp details while we don't have the settings mentioned above The insert to the database (postgresql) works ok. the field that I'm using is timestamp with time zone. The timezone set in my local DB is "Asia/Singapore" db value is: "2022-07-01 23:09:14.253877+08" which is correct. Now, if I try to retrieve this value, what I get from the Django object is: 2022-07-01 10:09:14.253877. which is totally of and not even close to UTC. The timestamp value got converted to a different timezone (like for MST which is -7 from UTC). But it's actually not following any pattern since I also had some test data added at 1:11:00PM but the stamp retrieved from the Django ORM is 00:11:28.848820 To summarize, my question is how does Django ORM treat a timestamp value if TIME_ZONE and USE_TZ settings are not configured. I was naive to expect that it will retrieve the value as is from the database but … -

how to add an image in a django project?
I created a search bar in a Django project and I want to add an image to it. The code for this search bar is in the templates folder listed by Django. Here is the code: /*For search bar*/ input { background-image:url(" images/loup.png "); background-position:left; background-repeat:no-repeat; padding-left:18px; width:175px; } ... ... <input type="search" name="search" placeholder="Search here..." autofocus x-webkit-speech/> In the same templates folder, I created an images folder which contained the image to display in the bar. But when I run my Django server, the search bar shows on a page, but the image does not. In order for Django to list the image path on the hard drive, I took inspiration from this question and the Django documentation and I added to my urls.py file this: urlpatterns +=static(settings.IMAGE_URL, document_root=settings.IMAGE_ROOT) and this to my settings.py file: IMAGE_URL = 'templates/images/' IMAGE_ROOT = os.path.join(BASE_DIR,'images') the STATIC_URL variable being already defined in my settings.py file. I moved my images folder into the staticfiles folder generated by Django. The error still reoccurs. Even when I change the path of my image in my index.html file: background-image:url(" ../staticfiles/images/loup.png "); -
Render in Django without return
I like to write code for a website using django where the user can make a request to a backend. Since the request takes some time to get the answer from the backed, I like to render the same page to include a loading animation. For this purpose, I set a variable "show_loading" on "true" to display the loading animation via the hmtl-file. The code is as follows: views.py def UploadView(request): show_loading = True context["show_loading"] = show_loading render(request,'UPLOAD.html',context) data = {} #something else happening, just logical operations return render(request,'UPLOAD.html',context) UPLOAD.html: {% if show_loading %} <div class="loader"> <div class="inner one"></div> <div class="inner two"></div> <div class="inner three"></div> </div> {% endif %} The problem is that the render function is not working by the first render line (without return) but with the second render line (with return). So the question is, does render always need return or what I am doing wrong here, that the render does not work without return? Thanks for your help in this matter. PS: I wish not to use javascript or something else, I like to use the django function with context -
Use dataset registed in on pipelines in AML
I was following the SDK v2 Python tutorial in order to create a pipeline job with my own assets. I notice that in this tutorial they let you use a csv file that can be downloaded but Im trying to use a registered dataset that I already registered by my own. The problem that I facing is that I dont know where I need to specify the dataset. The funny part is that at the beginning they create this dataset like this: credit_data = ml_client.data.create_or_update(credit_data) print( f"Dataset with name {credit_data.name} was registered to workspace, the dataset version is {credit_data.version}" ) But the only part where they refer to this dataset is on the last part where they # the line: registered_model_name = "credit_defaults_model" # Let's instantiate the pipeline with the parameters of our choice pipeline = credit_defaults_pipeline( # pipeline_job_data_input=credit_data, pipeline_job_data_input=Input(type="uri_file", path=web_path), pipeline_job_test_train_ratio=0.2, pipeline_job_learning_rate=0.25, pipeline_job_registered_model_name=registered_model_name, ) For me this means that I can use this data like this (a already registered dataset), the problem is that I don't know where I need to do the changes (I know that in the data_prep.py and in the code below but I don´t know where else) and I don't know how to set this: … -

Update a datetime field in django using an ajax call
I have a Profile model assigned to a user which contains the field : consent = models.DateTimeField(default=timezone.now, blank=True, null=True) I have created a switch in frontend in which the user gives consent for data tracking or no and and ajax call for handling the response.

How do I update an existing many to many field in Django REST?
I have a plot model like this: class Plot(models.Model): garden = models.ForeignKey('perma_gardens.Garden', on_delete=models.CASCADE) plant = models.ManyToManyField('perma_plants.Plant', related_name='%(class)s_plant', blank=True) def __str__(self): return self.name It contains a field for plants in many to many.

Django : Ignore a __in type filter in the queryset if it searches the empty list
Having this code sequence queryset = self.filter( brand_id__in=( UserObjectPermission.objects.filter( content_type=brand_ctype, user=user, ).values_list('object_pk') ) ) If there is no UserObjectPermission object that matches the filter content_type=brand_ctype, user=user then the end result will be empty queryset, because brand_id __in will search in [empty queryset].

Redirecting the user to the same page after POST
I'm building a tournament organizing tool but I have run into an issue. I have a view called index (currently the only view) that shows the tournament leaderboard as well as a table of unfinished matches and a table of finished matches. For each of the unfinished matches I have added an input field for each player where the user can type the scores. Each match also has a submit button. What I want to happen is that when the submit button is clicked, the match is finished and the match result (the scores in the input fields) are saved to the database. I then want the user to see the same page again (with the match moved from unfinished to finished). The problem I'm having is getting the player to be redirected to the same page again. I've tried looking around for similar questions and the answers to them and I have tried a couple of different things like if request.method == "POST": return render(request, './') or if request.method == "POST": return redirect(request.path) or if request.method == "POST": return index(request) all of them redirect me to /index.html which does not exist - my urlpatterns look like this urlpatterns = … -

Multiple translations for given entity in Django
I have a Django app, where one of the universal entities is called Organization. But this is a multitenant applications, and some tenants call their organizations 'Companies', another call them 'Pharmacies' - it depends of their business type. The types of organization are known upfront, so I can prepare translations for their names (in two or more languages) and store a preference which one to use. My question is: how can I select translation in the view depending of the tenant setting?
