Django signal conditionally update one table based on another
I'm working on my first django project that is a sports betting game. Here are my models: class Game(models.Model): home_team = models.CharField(max_length=200) away_team = models.CharField(max_length=200) home_goals = models.IntegerField(default=None) away_goals = models.IntegerField(default=None) class Bet(models.Model): gameid = models.ForeignKey(Game, on_delete=models.CASCADE) userid = models.ForeignKey(User, on_delete=models.CASCADE) home_goals = models.IntegerField() away_goals = models.IntegerField() score = models.IntegerField(default=None, null=True) First I create a game instance with null values in goals fields, then users make their bets. Once the game is over, I update game goals fields. Now I need to assign points for each user like this: WHEN bet.home_goals = game.home_goals AND bet.away_goals = game.away_goals THEN 2 WHEN game.home_goals > game.away_goals AND bet.home_goals > bet.away_goals THEN 1 WHEN game.home_goals < game.away_goals AND bet.home_goals < bet.away_goals THEN 1 WHEN bet.home_goals = bet.away_goals AND game.home_goals = game.away_goals THEN 1 ELSE 0 It seems that I should create a POST_SAVE singal to update Bet.score for each user based on update of Game.home_goals and Game.away_goals? But I have no idea how to do this -
Getting RIGHT JOIN with intermediate table with Django ORM?
I have these models: class Region(models.Model): region_name = models.CharField(max_length=64) def __str__(self): return self.region_name class GameRegionRelease(models.Model): region = models.ForeignKey( Region, on_delete=models.CASCADE, verbose_name='region' ) game = models.ForeignKey( Game, on_delete=models.CASCADE, verbose_name='game' ) release_date = models.DateField( verbose_name='release date', default=None ) class Game(models.Model): game_name = models.CharField(max_length=512) release_dates = models.ManyToManyField( Region, related_name='game_release_dates', through='GameRegionRelease' ) What I'm looking to get is every region listed for every game, even if there is no region data for that game. So the results would be Game x Region, with the region data filled in by GameRegionRelease where available. I'd want something similar to what the following would produce: SELECT * FROM gameslist_region gr CROSS JOIN gameslist_game gg LEFT JOIN gameslist_gameregionrelease grr ON gg.game_name = grr.game_id AND gr.region_name = grr.region_id; But I don't know how to express this in Django using native ORM constructs. Is this possible? I'm using Python 3.6.4 and Django 2.0.2. -
Multiple pagination in Django not working
I have 4 models: faculties, departments, studies and courses. I wanted a pagination for all the courses available and that was easy to achieve. But now I'm stuck because I wanted pagination for faculties also, that will show specific courses of the accessed faculty. The pagination will show for faculties as well, but problem is that if I try to go to the second page, it will redirect me to the second page of all courses list. Or, if I change page on all courses and then try to access a faculty, no course will show at all in the faculty. This is working: <div id="crs"> <h3>All courses</h3> <ul> {% for course in courses %} <li><a href={{ course.slug }}>{{ course.name }}</a></li> {% endfor %} </ul> <div class="pagination"> <span class="step-links"> {% if courses.has_previous %} <a href="?page=1">&laquo; first</a> <a href="?page={{ courses.previous_page_number }}">{{ courses.previous_page_number }}</a> {% endif %} <span class="current"> Page {{ courses.number }} of {{ courses.paginator.num_pages }} </span> {% if courses.has_next %} <a href="?page={{ courses.next_page_number }}">{{ courses.next_page_number }}</a> <a href="?page={{ courses.paginator.num_pages }}">last &raquo;</a> {% endif %} </span> </div> </div> This is not working: <div id="fac_{{ faculty.pk }}_tab" style="display:none;"> <h3> {{ faculty.name }} Courses</h3> <ul> {% for department in faculty.department_set.all %} {% for … -
Django channels for relatively large files ~10mb, is it a good idea?
I am trying to set up an infrastructure to upload test result data, part of it should be a django application that should handle the data transfer from a different source (typically txt files around 3 to 10 mb). I am considering both the api and django channels approach, but going through the documentation of django channels I read that it is only good for interoperability and not complex applications. Api seems a safe choice but it might not be as fast as django channels which use websockets. Should django channels be used to transfer files (txt, csv etc) ~10 mb? Does it work well or should I fall back in api choice? -

How to apply two different mock.patches to one unit test?
When I'm trying to run this test: from unittest import mock @mock.patch('requests.get', side_effect=mocked_requests_get) @mock.patch('requests.post', side_effect=mocked_requests_post) def test_zeros(self, response): self.assertEqual(0, 0) it says TypeError: test_zeros() takes 2 positional arguments but 3 were given. So, how can I mock two different methods (I need requests.get and requests.post) in one test? -
Django restrict access to TemplateView
I'm using TemplateView to display swagger pages (local files). However, now I need to restrict access. Using a normal view, I could use @login_required mixin on the view. Is there a way to do that with TemplateViews? Or should I be using some other way of displaying these swagger pages? url(r'^swagger/', TemplateView.as_view(template_name='swagger.html'), name='swagger'), -
Django post-office: unable to open email attachement
I've written a django view that loads a number of PDF files and combines them into a .zipfile. I dont want to save the object on the server, so I am using StringIO() This is done with the following code: zip_buffer = StringIO.StringIO() summary_filename = 'summary' + str(user) + '.pdf' with zipfile.ZipFile(zip_buffer, mode='w', compression=zipfile.ZIP_DEFLATED) as zf: for file in attachements: zf.write(str(settings.MEDIA_ROOT) + '/' + str(file[0].file), file[1] + '.' + str(file[0].file).split('.')[-1]) zf.writestr(summary_filename, pdf) When I was debugging the code I had it return the object as a download in the browser through the following code response = HttpResponse(zip_buffer.getvalue(), 'application/x-zip-compressed') return response This all works as intended, when I click the button a .zip file is downloaded by the browser that contains all of the information. The problems started when I wanted to email the file as well. I am using Django post-office And intitally tried sending the email with the following command: attachment_file = zip_buffer.getvalue() send_email([requester.email], email_template context, attachments={'summary.pdf': attachment_file}) The attachement file is exactly the same as the one I supplied to the browser, yet this causes the following exception: file() argument 1 must be encoded string without NULL bytes, not str I then tried something different: send_email([requester.email], 'userprofile_summary', requester.profile.tenant, … -
Create multiple Django model instances using for loop
I have three Django models namely User, Project and Hourly. User model: which represents a standard Django user, which can start a new project. Project model: Represents a project, containing project specifc constants such as Time Zone, site latitude, site longitude, etc… Hourly model: Which represents all the hourly values (clock-time, solar time, solar hour angle, etc…) for a certain project. To simplify the problem the Hourly model has only two fields, namely project and clock_time. Eventually I would like to use fields to store these to the database. In addition I override the Project.objects.create(….) method using the ProjectManager() class. The meaning of this is that I would like to generate 8760 new hourly instances whenever a new project is created. How to implement this? At the moment every time only one Hourly object is created, whener Projects.object.create() is called. The Project and Hourly models and the ProjectManager are defined as follows: User = settings.AUTH_USER_MODEL class ProjectManager(models.Manager): """""" def create(self, owner, project_name, TMZ, lat, lon): project = super().create(owner=owner, project_name="CREATED BY PROJECTMANAGER", TMZ=TMZ, lat=lat, lon=lon) project.save() # Next I would like to delete all existing Hourly objects tied to this project hourly = Hourly.objects.filter(project=project) hourly.delete() # Next I would like to … -
Django formset , queries for relational field for every form
Models.py class Material(BaseModelClass): material = models.CharField(max_length=25, verbose_name='Material') def __str__(self): return self.material class PurOrder(BaseModelClass): order_number = models.CharField(max_length=25) class PurOrderItem(BaseModelClass): order = models.ForeignKey(PurOrder, on_delete=models.CASCADE) material = models.ForeignKey(Material, on_delete=models.PROTECT) I created a PurOrder form and PurOrderItem formset PurOrderForm = modelform_factory(PurOrder, fields=('order_number',)) PurOrderFormset = inlineformset_factory(PurOrder, PurOrderItem,fields=('material',)) Initialized them as follows. form = PurOrderForm(instance=order_instance) queryset = order_instance.purorderitem_set.all().select_related('material',) formset = PurOrderFormset(instance=order_instance, queryset=queryset) This setup costs me 22 queries if there is 20 PurOrderItem for selected purorder. 1 for PurOrder instance, 1 for PurOrderItem instance 20 for selected materials for those PurOrderItem's. Think of it, it there is 1000 PurOrderItem With the provided select_related, it add's material to PurOrderItemselect, but when it comes to display it I think, it query again. I use django-autocomplete-light, so it saves me from quering all material instances, but it keeps quering selected material, to display it even though I select_related material. Ideally, I would select PurOrder instance with prefetched purorderitem and related materials, these means 3 queries. Prefetched purorderitem's and material's will be used, when it's their turn. Please advice me a way to avoid selected choices query. Note: Caching is not an option, if possible. -
Show and Edit M2M filelds in both Admin Panel Models (django-select2)
I have some problem with ModelSelect2MultipleWidget when I set him for custom field. models.py class Product(GenerateUniuqSlugMixin, BaseAbstractModel): name = models.CharField( verbose_name='Имя', max_length=255 ) slug = models.SlugField( verbose_name='Url', max_length=100 ) description = models.TextField( verbose_name='Описание', blank=True ) price = models.ManyToManyField( 'Price', verbose_name='Цена', blank=True, related_name='products' ) class Price(BaseAbstractModel): code = models.CharField( verbose_name='Уникальный Код', max_length=100, unique=True, db_index=True ) price = models.DecimalField( verbose_name='Цена', max_digits=16, decimal_places=2 ) creation_date = models.DateField( verbose_name='Дата добавления', auto_now_add=True ) update_date = models.DateField( verbose_name='Дата обновления', auto_now=True ) I want have opportunity for searching and connecting products from Price Admin Panel. And I added for forms next code: class PriceAdminForm(forms.ModelForm): products = forms.ModelMultipleChoiceField( queryset=Product.objects.all(), widget=ModelSelect2MultipleWidget( model=Product, queryset=Product.objects.all(), search_fields=['name__icontains'], attrs={'data-placeholder': 'Поиск в товарах', 'data-width': '50em'} ), required=False ) class Meta: model = Price fields = ( 'code', 'name', 'price', 'products', ) But it's not working and I don't know why, where my mistake? If I remove ModelSelect2MultipleWidget from widget attr I see default choice field, but he don't remeber my save choice he just show all queryset. It will be great if I can see input field which offer ModelSelect2MultipleWidget. Thank's. My environment: Django==2.0.2 django-select2==6.0.1 -
Django: Include template with variables rendered from views.py into another template
I have a template plot.html inside app plot: <div> {{ plot|safe }} </div> some other divs here The plot variable is calculated from views.py inside app plot: class RenderView(TemplateView): def __init__(self): self.template_name = "plot.html" def get_context_data(self, **kwargs): context = super(RenderView, self).get_context_data(**kwargs) context['plot'] = PlotView().make_plot() return context Now I want to include this template with the generated plot and other divs into another template from another app, another.html: {% include "plot.html" %} of course this does not generate the plot and other info from the views.py file.

automatically changing model field in Django
Consider a Blog model as below: class Blog(models.Model): text = ... stage = ... # ChoiceField Blog.stage describes the current stage the blog is in which can take many values like edit, content verification, tag etc. Transition from one stage to another is based on a condition. In content verification stage, a user verifies the content of the model and corresponding entries are recorded in the following model. class ContentVerificationModel(models.Model): user = ... #verifier blog = ... # blog being verified do_you_verify_blog_content = ... # BooleanField To move from content_verification_stage to next stage, say, edit stage, following conditions must be satisfied: Blog must be verified by some minimum number of people (Say, 10) Percentage of people who voted for the blog must be greater than some minimum value (say, 60 i.e. 6 out 10 entries for a blog must have do_you_verify_blog_content value as True) How do I manipulate my code so that a model field can be changed automatically when some conditions are met? -
Prevent/allow a hyperlink click conditionally through Ajax in Django
I'm trying to implement a hyperlink on a page which when clicked, will submit through ajax first, run a couple checks determining whether or not the user has the authority to visit the hyperlink-page, and then either allow them to go through or prevent the hyperlink's default action(and raise errors). I've set up the code, and the ajax request will go through, but will not be handled server-side. Here is the template code: <a class='btn btn-primary pairing-CTA-btn' href="{% url 'profile:request' object.user %}">Send {{object.user | upper}} a Request</a> The js: $(document).ready(function(){ var $myButton = $('.pairing-CTA-btn') $myButton.click(function(event){ var $buttonData = $(this).serialize() var $endpoint = $myButton.attr('data-url') || window.location.href // or set your own url $.ajax({ method: "GET", url: $endpoint, data: $buttonData, success: handleSuccess, error: handleError, }) }) function handleSuccess(data, textStatus, jqXHR){ // No need to do anything here. Allow link click. console.log(data) console.log(textStatus) console.log(jqXHR) } function handleError(jqXHR, textStatus, errorThrown){ // on error, prevent default, bring up errors event.preventDefault() // $('.pairing-CTA-btn-errors').text("YOU SHALL NOT CLICK BUTTON"); // $('.pairing-CTA-btn-errors').show(); console.log(jqXHR) console.log(textStatus) console.log(errorThrown) } }) The View where this link exists: class ProfileDetailView(AjaxRequestButtonMixin, DetailView): template_name = 'user_profile/profile_detail.html' And the ajax mixin referenced above: class AjaxRequestButtonMixin(object): def button_allowed(self): print("AJAX") # response = super(AjaxFormMixin, self).form_invalid(form) if self.request.is_ajax(): # PERMISSION-TO-CLICK-LINK … -
Run Angular App, Django Backend and MySql on separate servers
We are trying to build a system with Angular as frontend, Django as backend and MySql as database. We want all three to run on separate servers (standalone angular app and django back end).

Django REST FrameWork JWT does not allow to provide data or decode itself
I have these endpoints: urlpatterns += [ path('api-token-auth/', obtain_jwt_token), path('api-token-verify/', verify_jwt_token), path('api-token-refresh/', refresh_jwt_token), path('api/', include(router.urls)), ] For example I have a User on backend, and let's say hey wants to login to the system. In login page he must provide his username and password, and login page will use "obtain_jwt_token" endpoint, which will automatically check if that user exists or not. If not, backend will return error message, if that User exists and username & password is correct than backend will return a Token, generated by JWT, and that token will live for let's say 1 hour. But the problem is that backend will not return additional data, it will return only Token itself, but not id of that user or something. And that is the problem. Am I understanding something wrong ? All I want is for backend to return not on the Token, but also id of that user. Or to decode the Token, and get id of User from it. -
Django: show OTP verification dialogue right after submitting form in a modal
First website. I am using Django. I am stuck with implementing this functionality. I right now am able to show a signup form in a modal dialogue and also I can save the details to backend. Now I want to add OTP step to the signup process. What I don't know is how do I move to OTP modal for phone number verification without losing user detail form in the modal. After user enters the correct code how do I save the details that were filled up in previous(signup) modal? So it is two steps: 1. Show Signup Modal. 2. Show OTP verification Modal. How to go to step 2 without losing data entered in step 1. Can anyone please give me an example or idea how it is done? Thank you. -
