long running task manager project
I have to implement a project in which the user can stop the long-running task at any given point in time, and can choose to resume or terminate it. This will ensure that the resources like compute/memory/storage/time are used efficiently at our end, and do not go into processing tasks that have already been stopped (and then to roll back the work done post the stop-action). I also have to create Rest API endpoints. Can anyone help with intuition? -
Adding your own language for translation in Django
We need to make a translation into the Bashkir language on the site. This does not seem to exist in the locale django file. I'm trying to do this. In the settings.py file added. import django.conf.locale EXTRA_LANG_INFO = { 'ba': { 'bidi': False, 'code': 'ba', 'name': 'Bashkir', 'name_local': 'башкирский' }, } d = django.conf.locale.LANG_INFO.copy() d.update(EXTRA_LANG_INFO) django.conf.locale.LANG_INFO = d LANGUAGE_CODE = 'ru' LANGUAGES = ( ('ru', 'Russian'), ('en','English'), ('ba', 'Bashkir'), ) Now, when following the link, it writes that it cannot find the / ba page. I display links on the page as follows.(When switching to ru and en, the translation goes without problems). {% for language in languages %} <a href="/{{ language.code }}/"}>{{ language.code }} </a> {% endfor %} in urls + = i18n_patterns added. Maybe there is some other way? Or how to finish the given one? -
Using App name with Django.contrib.auth views
I am new to Django and I am creating a user change password page. However, I keep encountering a NoReverseMatch error which I suspect is due to my app name but I am not able to resolve it even after spending hours googling for a solution.

Get constant incoming post requests from multiple devices with Django Rest Framework or listen TCP Server Socket
I have IoT devices which are rfıd readers. This devices send stream data with HTTP Post message. I use Django to get data from these devices. While receiving this data, I can write a function to get data from post requests coming directly with Django and receive the data from the request in this function with Django REST Framework or I can listen with a TCP Server socket. Which of these two approaches is more suitable for retrieving data? Because when I use a TCP Server socket, Django REST Framework does not work for HTTP requests, only the TCP socket works. -
How to add a property to a model which will be calculated based on input?

But if I just add property, it can not be calculated with me_user user in mind, AFAIK the property can only access the local model fields like "from_account" or "to_account". -

Django sessions doesn't allow me to add items in my cart
I am creating an eCommerce store and I use Django sessions to store the cart information. However, for some reason, only 2 items get stored in the cart and no more. Once I add the first item, it stays there as it is. Then I add the 2nd item. However, when I add the 3rd item, the 2nd item is overwritten by the 3rd one, still keeping only 2 products in the cart. I feel it would be a simple logic error but I can't seem to figure it out. My views.py... def shop(request): if not request.session.get('order1'): request.session['order1'] = [] if request.method == "POST": quantity = int(request.POST.get('quantity')) name = request.POST.get('name') if quantity >= 1: request.session.get('order1').append({"quantity":quantity, "name":name}) context = { "check":request.session.get('order1'), } else: messages.warning(request, "You have entered an invalid quantity") context={} else: context={} return render(request, "store/shop.html", context) And the output of the context = {"check":request.session.get('order1')} is something like this [{'quantity': 1, 'name': 'Tissot Watch for men - black star striped'}, {'quantity': 2, 'name': 'Jewelry Bangles Stripes for Girls'}] and always stays with only 2 items. Is there any error in the code that I have done? Any help would be greatly appreciated. Thanks! -

How to shrink flexbox when downsizing image
I am using flexbox to center items on a page and also to center items within a row. I have to handle potentially large images within the row, so I am using max-width=40% to downsize the image. However, when I do this the flexbox for the applicable row does not shrink to fit the new image size, but retains the size as if the image is still max-width=100%. How can I make the flexbox row smaller to account for the 40% max width property? Here current html code: <div style="display: flex; flex-direction: column; align-items: center;> <label>This is my header.</label> <div style="display: flex; flex-direction: row; align-items: center; border: 1px solid black;"> <img style="max-width: 40%; padding: 5%;" src="path_to_my_image" alt="(!)"/> <div style="border: 1px solid black"> <label>Here is my label</label><br> <label>Here is another label</label> </div> </div> </div> This is an image of what the current display looks like with a border around the flexbox row: Here is what it looks like without setting max-width (bottom cropped to fit): -
Ajax post requests seem to not work for some users?
I've been testing my site by having friends try it, and some friends have an issue where some of my javascript functions don't work, and some functions do. After figuring out it's not their browsers or devices, I noticed the functions that weren't working for them were the ones with Ajax post requests, so I think that's the issue here. Does anyone know why Ajax post requests work for only some users? Also, FYI, I'm using Django as a framework. Example of one of my functions using ajax: $('#button').click(function(){ $.ajax({ url: '/get_url/', type: "POST", data: { data_name: data_to_send }, beforeSend: function (xhr) { xhr.setRequestHeader("X-CSRFToken", csrftoken); }, success: function (data) { //change some html text using data }, error: function (error) { console.log(error); } }); }); -
How to capture selected values, in Django, from two separate select fields and pass it to the view upon form submission?
I am trying to create a filtered list from model class "Animal" based off of two separate select field drop down values. If user selects "baby" and "dog" then a list of puppies would be generated from the Animal model. I cannot seem to figure out how to capture the value pks for both the "age_group" and "type" fields so that I can use them to filter the queryset. Any suggestions or guidance is appreciated. I am very new to Django. models.py class Animal(models.Model): name = models.CharField(max_length=500, blank=False, null=False) type = models.ForeignKey(Type, on_delete=models.SET_NULL, blank=False, null=True) ageGroup = models.ForeignKey(AgeGroup, max_length=300, on_delete=models.SET_NULL, blank=False, null=True) age = models.PositiveIntegerField(blank=False, null=False) sex = models.CharField(max_length=100, choices=SEX, blank=False, null=False, default='NA') breedGroup = models.ManyToManyField(BreedGroup, blank=False) breed = models.ManyToManyField(Breed, blank=False) tagLine = models.CharField(max_length=300, blank=False, null=False) goodWithCats = models.BooleanField(blank=False, null=False, default='Not Enough Information') goodWithDogs = models.BooleanField(null=False, blank=False, default='Not Enough Information') goodWKids = models.BooleanField(null=False, blank=False, default='Not Enough Information') forms.py class AnimalSearchForm(ModelForm): chooseType = ModelChoiceField(queryset=Animal.objects.values_list('type', flat=True).distinct(),empty_label=None) chooseAge = ModelChoiceField(queryset=Animal.objects.values_list('ageGroup', flat=True).distinct(), empty_label=None) class Meta: model = Animal exclude = '__all__' views.py class VisitorSearchView(View): def get(self, request): animalList = AnimalSearchForm(self.request.GET) context = {'animal_list': animalList} return render(request, "animals/landing.html", context) templates {% extends 'base.html' %} {% block content %} <h1>Animal Search</h1> <form class="form-inline" action="." method="POST"> {% … -
POST 500 error django react site, POST /api/create-room
I have created a component for a Django React Rest Framework site and I keep getting an error when I click on the Create Room button on my site. The error seems to be located at the fetch portion of the component for the CreateRoom.js file I created. Any help in identifying the issue is much appreciated. Here is the error and the code that seems to be triggering the error. Please take a look at what I've got and let me know if I can provide any more information to help figure out what the issue is. Usually I try and figure it out myself but I've spent hours doing so and haven't been able to figure it out.
