How to receive and save data via ajax in django?
through ajax I am sending the data correctly, because the data I see through wireshak and they are correct. On the django server, he sends me the correct request "POST / solit / HTTP / 1.1" 200 52. But the value sent does not receive it, it does not reach the Mysql database and I do not understand why, if the traffic sends well the data. In wireshak I see the data of the post request, they are the correct ones, but they are not saved in the database, when I want them to be added as if I were to update the record of such database fields and it does not , I do not understand why this is my views.py def solit(request): if request.method == 'POST' and request.is_ajax(): form = addiForm(request.POST) if form.is_valid(): peticion = form.save() if peticion.usuario: peticion.usuario.d_pendientes = form.cleaned_data.POST.get['dias_adicionar', None] # Get the form value if has, otherwise assign it to None (change it if you want another default value) peticion.usuario.h_pendientes = form.cleaned_data.POST.get['horas_adicionar', None] # The same peticion.usuario.save() print (request.get) return JsonResponse({'status': 'true', 'msg': 'Procesado Correctamente'}) else: return JsonResponse({'status': 'false', 'msg': 'Los datos no son validos'}) form = addiForm() return render(request, 'plantillas/adicionar.html', {'form':form}) This is my … -
Django app changes in server after a while
I'm running a Django app on an AWS EC2 instance. When I upload the app it works fine for a while and all of a sudden some problems appear. First, it doesn't find the media folders that initially found and second, if I fix the paths to the media folders, it returns a problem with urlpatterns, which doesn't make sense since the app works for an hour or so until it doesn't. To fix the issue I have to reupload the app but after a couple of hours it happens again. Any solutions? -
How to Embed a Plotly Interactive Graph in Webpage
I have an interactive graph generated by Plotly in Python that I saved to an html file using plotly.offline.plot(fig, filename='/tmp/interactiveGraph.html') I am now trying to embed this interactive graph into some kind of webpage, using either Dash or Django. I'm leaning toward Django at the moment, given that I have an html version of the graph. Which would be better? My code for the webpage is in a separate file from the code where I am creating the graph. A lot of the tutorials I've found online just say to add a few lines to the template, but I don't know how to get those lines that they've described. tl;dr: I'm looking for guidance as how to integrate an html file-for a Plotly interactive graph-with a web python script using Django or Dash Reference: https://github.com/ricleal/DjangoPlotLy https://www.pythonsetup.com/how-implement-data-visualization-django-and-plotly/ -
Django filter objects based on property in ForeignKey set
I have models that look something like this: class Type(models.Model): name = models.CharField(max_length=50) notes = models.CharField(max_length=50) class Instance(models.Model): type = models.ForeignKey(Type, on_delete=models.CASCADE) color = models.CharField(max_length=50) quantity = models.PositiveIntegerField() I want to get a list of all Types that have at least one Instance whose quantity is greater than 0. How can I express that? In (pseudo) vanilla Python, this would be something like: [type for type in Type.objects.all() if type.instance_set.objects.filter(lambda instance: instance.quantity > 0)] I tried available_types = Type.objects.filter(Q(instance_set__contains=Q(quantity__gt=0)) but this doesn't work because Django is looking for quantity as an attribute of Type, and of course doesn't find it, because it's an attribute of Instance. -

Change Django setting ALLOWED_HOSTS in settings.py only when running pytest
I've got a test that I'm trying to run where I login to my django application: class FirefoxTestCases(StaticLiveServerTestCase): def setUp(self): data_setup.basic_apps_setup(self) self.browser = webdriver.Firefox() def tearDown(self): self.browser.quit() def test_log_in_with_no_apps_displays_firefox(self): # Opening the link we want to test self.browser.get(self.live_server_url) assert "log in" in self.browser.page_source time.sleep(2) self.browser.find_element_by_id("id_username").send_keys("userone") self.browser.find_element_by_id("id_password").send_keys("test") self.browser.find_element_by_id("log_in").click() time.sleep(2) # Check the returned result assert "Something appears to be missing" in self.browser.page_source In doing this - it doesn't actually allow the login because in my settings I have specific ALLOWED_HOSTS setup.

How do I Force db commit of a single save in django-orm in a celery task

How to pass context from views to JS file Django

How to call a view with many parameters
I am trying to create a very simple custom view for my application. Lets imagine I have a simply model: class Person(models.Model): Name = models.CharField(max_length = 255) pass class Company(models.Model): Title = models.CharField(max_length = 255) pass I would like to display a list of objects. On one url - list of person, on another - list of companies. So I create simply views: def PersonListView (request): _persons = Person.objects.all() context = { "object_list": _persons } return render (request, "PersonListView.html", context) def CompanyListView (request): _companies = Person.objects.all() context = { "object_list": _companies } return render (request, "CompanyListView.html", context) Then add path to urls - /Person for list of persons and /Company for list of companies. urlpatterns = [ path('/Person', PersonListView), path('/Company', CompanyListView) ] All working well. But I already have a question 1. Why my view function have a request variable, but I can call this function from urls without defining this variable? 2. Why I can't use this syntax path('/Person', PersonListView**()**)? What is wrong with this brackets? And another part of my question. But then I decided to make some refactoring - I intended to use one view both for person and companies, so I have to pass a variable … -

Django - how do I override default date formats per locale?
We are using Django 1.11 for Speedy Net. I want to override the default values of DATE_FORMAT and MONTH_DAY_FORMAT in English, but keep the default values (or define them again) in Hebrew. So they will not be the same and will not be identical to Django's default values. In English we will have: DATE_FORMAT = 'j F Y' MONTH_DAY_FORMAT = 'j F' And in Hebrew: DATE_FORMAT = 'j בF Y' MONTH_DAY_FORMAT = 'j בF' The template currently looks like this: {% if can_view_profile and user.date_of_birth %} {% if can_view_dob_day_month or can_view_dob_year %} <tr> <th>{% if can_view_dob_day_month %}{% trans 'Birth Date' %}{% elif can_view_dob_year %}{% trans 'Birth Year' %}{% endif %}</th> <td> {% if can_view_dob_day_month and can_view_dob_year %} {{ user.date_of_birth|date:settings.DATE_FORMAT }} {% elif can_view_dob_day_month %} {{ user.date_of_birth|date:settings.MONTH_DAY_FORMAT }} {% elif can_view_dob_year %} {{ user.date_of_birth|date:'Y' }} {% endif %} </td> </tr> {% endif %} {% endif %} And I want it to display the dates in these formats in each language.

Restrict or check for multiple data entries before saving in Django
How can restrict or checking data entries before saving? Example So i have different Dogs who are eating Meals with different Sizes (in Gramm) and different Foodtypes (Pork, Beef etc.). models.py class Dog(models.Model): name = models.CharField(max_length=255) meal = models.ManyToManyField('Meal') def __str__(self): return self.name class Meal(models.Model): food = models.ForeignKey('Foodtype', null=True, blank=False, on_delete=models.SET_NULL) min_g = models.PositiveIntegerField() max_g = models.PositiveIntegerField() def __str__(self): return 'Meal: %s Size: %s g to max. %s g' % (self.food, self.min_g, self.max_g ) class Foodtype(models.Model): name = models.CharField(max_length=255) def __str__(self): return self.name Every Time i enter a new Dog i also can create a new Meal. For Instance i added Harry (Dog.name) who is eating Beef (Foodtype.name) of a Size min. 200 (Meal.min_g) gramm to 300 (Meal.min_g) gramm So in my Meal Table is now a Entry of Beef, 200, 300 But Harry the Dog can have multiple Meals so i choose also Pork, 200, 300. If a other user now enters a new Dog who is eating exactly the same, the user could choose the data-point Beef, 200, 300 but he could also easily end up with a double entry by accident because it is a many-to-many relation (see following picture). On the Other Hand i need this … -

I tried deploying a project on ubuntu machine on AWS but the site doesn't load as it's not there.

Has anybody experience with the django-star-ratings plugin from wildfish?
I want to use a star rating system but I'm a bit overwhelmed. I found this django plugin: https://django-star-ratings.readthedocs.io/en/latest/?badge=latest%2F# I have a form where a user can rate a product. The user should be able to rate the product by clicking on the stars(with hower effects would be nice). Then this rating value (0-5) should be saved in my database. Currently I only have a field where a number can be entered and with a post request I save the data to my database. I also show all the reviews on my product page and it would be idealy when I also could use this plugin. So if there is someone that has experience with this plugin...is it possible to do all of this stuff with this plugin? Please let me know if you need more information. At the moment i use a combination of HTML CSS and JavaScript to show the stars on my product page but I think there is a more elegant slution and additionally I have no idea how I can implement that the users are capeable of clicking on the stars in the review form with my current solution.
