Django display table in templates
I am using Django 2.0.1, and I have the following code: Models.py: class Category(models.Model): category_name = models.CharField(max_length=50) class CategoryItems(models.Model): category_name = = models.ForeignKey(Categories, related_name='categoriesfk', on_delete=models.PROTECT) item_name = models.CharField(max_length=50) item_description = models.CharField(max_length=100) Thereafter my views.py: def data(request): categories_query = Categories.objects.all() category_items_query = CategoriesItems.objects.all() return render_to_response("data.html", {'categories_query': categories_query,'category_items_query': category_items_query} In the template I'm trying to display all items for each category, for example, suppose there are 4 categorizes, e.g. Bicycle, then it display all items belonging to that category only. For example, as follows: Category 1: Category_Item 1, Category_Item 2, Category_Item 3, and so on ... Category 2: Category_Item 1, Category_Item 2, Category_Item 3, and so on ... I have tried to write so many different for-loops, but they just display all items, I need it to show items only for that category, then for loop to next category and show items for that. Please may I kindly ask for some help? -

Django : changing a specific form in modelformset
Here is the riddle. This is a simplified version of the problem I am dealing with, just so we can capture the core problem. So, for the sake of simplicity and relevance, not all fields and relationships are shown here. So, I have a modelformset and I would like to access each individual form to change the field based on the queryset. class PlayerType(models.Model): type = models.CharField(max_length=30, choices = PLAYER_TYPES) class Player(models.Model): name = models.CharField(max_length=30, blank=False, null=False) player_type = models.ForeignKey(PlayerType, related_name ='players') contract_price = models.DecimalField(max_digits = 10, decimal_places = 2, blank = False, null = False) price_unit_of_measurement = models.CharField(max_length=20, choices=STANDARD_UOM) Forms.py class PlayerForm(ModelForm): class Meta: fields = ['name','price_unit_of_measurement'] views.py PlayerFormSet = modelformset_factory(Player, form = PlayerForm, extra = 5) Now, say I want to display a different unit of measurement depending on which player I am showing. For instance, player 1's contract may be based on lump sump or amount per game, and another player's contract may be based on number of minutes played, price per month, etc. depending on the player type. In essence, I would like to know how to access each form in a modelformset and change the unit of measurement for that form alone, from the default … -

Always image cannot be sent normally
Always image cannot be sent normally. I wrote in views.py def photo(request): d = { 'photos': Post.objects.all(), } return render(request, 'registration/accounts/profile.html', d) def upload_save(request): form = UserImageForm(request.POST, request.FILES) if request.method == "POST" and form.is_valid(): data = form.save(commit=False) data.user = request.user data.save() return render(request, 'registration/photo.html') else: return render(request, 'registration/profile.html') in profile.html <main> <div> <img class="absolute-fill"> <div class="container" id="photoform"> <form action="/accounts/upload_save/" method="POST" enctype="multipart/form-data" role="form"> {% csrf_token %} <div class="input-group"> <label> <input id="file1" type="file" name="image1" accept="image/*" style="display: none"> </label> <input type="text" class="form-control" readonly=""> </div> <div class="input-group"> <label> <input id="file2" type="file" name="image2" accept="image/*" style="display: none"> </label> <input type="text" class="form-control" readonly=""> </div> <div class="input-group"> <label> <input id="file3" type="file" name="image3" accept="image/*" style="display: none"> </label> <input type="text" class="form-control" readonly=""> </div> <div class="form-group"> <input type="hidden" value="{{ p_id }}" name="p_id" class="form-control"> </div> <input id="send" type="submit" value="SEND" class="form-control"> </form> </div> </div> </div> </main> In my system,I can send 3 images at most each one time, so there are 3 blocks.Now always program goes into else statement in upload_save method, I really cannot understand why always form.is_valid() is valid.When I send only 1 image, same thing happens.So the number of image does not cause the error.How should I fix ?What is wrong in my code? -
Django get_or_create race condition when creating related objects
I have an ExtendedUser model like this, that just points to Django's User model: class ExtendedUser(models.Model): user = models.OneToOneField(User) When a request comes in, I want to get or create an User and its related ExtendedUser if the user that I'm looking for doesn't exist. I have this code : def get_or_create_user(username): with transaction.atomic(): user, created = User.objects.get_or_create( username=username, defaults={ 'first_name': "BLABLA", }, ) if created: extended_user = ExtendedUser() extended_user.user = user extended_user.save() return user I wrap it inside a transaction, to be sure I don't create an User but not its associated ExtendedUser. But, when two requests come in simultaneously that will create the same user, this fails from time to time with an IntegrityError, for both requests. So I end up with no user being created.. IntegrityError: (1062, "Duplicate entry 'BLABLABLA' for key 'username'") Note that I use MySQL, but I force READ COMMITTED isolation level. What do I do wrong ? How should I handle this ? The models need to stay as they are. -
Django 2.0 FormView for searching
I am using Django for few weeks, so I am still bit new in this. I want a page where I will have searching form and table with results. So each time I click search it will stay on same page and results will changed. I did read a lot of threads here about that, but some of them are old.

Python unit test : Why need `mock` in a test?
I can not understand why we need mock in some test cases, especially like below: main.py import requests class Blog: def __init__(self, name): self.name = name def posts(self): response = requests.get("https://jsonplaceholder.typicode.com/posts") return response.json() def __repr__(self): return '<Blog: {}>'.format(self.name) test.py import main from unittest import TestCase from unittest.mock import patch class TestBlog(TestCase): @patch('main.Blog') def test_blog_posts(self, MockBlog): blog = MockBlog() blog.posts.return_value = [ { 'userId': 1, 'id': 1, 'title': 'Test Title, 'body': 'Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy\ lies a small unregarded yellow sun.' } ] response = blog.posts() self.assertIsNotNone(response) self.assertIsInstance(response[0], dict) This code is from this blog. What I'm curious about is that as you can see in test code, test code set blog.posts.return_value as some desirable object(dict). But, I think this kind of mocking is useless because this code just test How well the user set the return_value correctly in the test code, not what the real Blog' object really return. What I mean is, even if I make real posts function return 1 or a in main.py, this test code would pass all the tests because the user set the return_value correctly in the test code! Can … -
How to serve a view at every URL endpoint
The reason for my wanting to serve the same view at every URL endpoint, is because the view sends Notification information to the authenticated user. For example, here is the view which has data that I would like served in every page: class NotificationsView(View): def get(self, request, *args, **kwargs): profile = Profile.objects.get(user__username=self.request.user) notifs = profile.user.notifications.unread() return render(request, 'base.html', {'notifs': notifs}) I'm trying to send the context variables into my template to be used with javascript. The JS file lives apart from the template, so I'm attempting to declare the global JS vars in the base template first, then use them in the JS file. base.html: ... {% include "landing/notifications.html" %} <script src="{% static 'js/notify.js' %}" type="text/javascript"></script> {% register_notify_callbacks callbacks='fill_notification_list, fill_notification_badge' %} landing/notifications.html: <script type="text/javascript"> var myuser = '{{request.user}}'; var notifications = '{{notifs}}'; </script> notify.js: ... return '<li><a href="/">' + myuser + notifications + '</a></li>'; }).join('') } } Based on this code, you can see how I've ended up in a predicament where I need to use the CBV to send the proper notifications to the landing/notifications.html in order to make sure the javascript variables can be dynamically rendered for the JS file. I am utterly confused as to how the … -

In Django test there is empty queryset when assigned to variable but not empty when printed in console during debug
I'm debugging Django (1.11.8) test and observing strange behavior: when stopped in debugger and switched to Ipython console typing: Model.objects.all() returns non-empty Queryset. However, when the same expressions is assigned to variable e.g.: obj_qs = Model.objects.all() then obj_qs is empty Queryset. I would expect the same result from both statements. Am I missing something important in tests setup? I'm using both setUpTest() and setUp() methods to initialize objects for the test. -
