Filtering the Users only if conversation occurred
Here's my Model class Message(models.Model): sender = models.ForeignKey(User, related_name="sender") receiver = models.ForeignKey(User, related_name="receiver") msg_content = models.TextField() How can I filter out the Users only if, either Current User have sent them a message or they have sent Current User a message, as we see on Social Networks? I tried something like this users = Message.objects.filter(Q(sender=request.user) | Q(receiver=request.user)) But it's not working. It's filtering the user equal number of times as conversation occured. When i used Message.objects.filter(Q(sender=user) | Q(receiver=user)).distinct('sender') It's raising an error that "DISTINCT ON fields is not supported by this database backend" (sqlite3) Please help me with this code. Thanks in advance! -
How to add a non-Django python package to a Django project?
This is probably one of those annoying newbie questions. I'm trying to use a python package called jieba in my Django project. I've tried pip install and dragging the package folder into my apps directory, but have not succeeded in importing the package (ModuleNotFoundError). Please tell me how this could be done. Thanks! -
Django Error - unsupported operand type(s) for +: 'int' and 'strTypeError at

How to use previously defined methods (funcs) in "export" function in Python/Django?
Been updating a Python/Django project, and I know pretty much nothing about it, whatsoever. Currently I have been trying to export a current view (change list) to CSV. The columns are printed fine, all the methods (functions) are displaying all info as they should/expected. When hitting "Export" link the hardcore starts, and it's been up for weeks now. Finally something started to show in my .csv file, yet still I cannot print out methods like how_many or postal_code inside the loop for elem in csv_elements: Below is a partially printed class that takes care of displaying columns on the screen and then export them to the .csv file. I didn't include all of it, just parts I personally think are important to show (I may be very wrong about this of course). Basically everything down to export_this_list works just fine. What syntax should I use to be able to re-use already defined functions (methods) inside the last function (method)? class EnrolmentAdmin(TrainingAdminMixin, admin.ModelAdmin): """EnrolmentAdmin is used for registering Enrolment model.""" form = EnrolmentForm . . list_display = ('date', 'training', 'postal_code', 'how_many') . . def postal_code(self, obj): return obj.invoice_data['postal_code'] def how_many(self, obj): return obj.total_participants how_many.short_description = "How Many Persons" . . def … -
How to stop Djago/PSQL from auto-incrementing table ID on creation failure
Currently, I have a Django project with an ItemReport table that only allows for 1 entry per day per item. Everything is fine and all except that whenever it fails with an IntegrityError (i.e. my project tried to create an ItemReport on a day when an ItemReport already exists, the object ID increments anyway. For example: September 1: Report for September 1 (ID 1) September 2: Report for September 1 (ID 1) Report for September 2 (ID 5) Models as follows: class ItemReport(BaseModel): fk_item: Item = models.ForeignKey(Item, null=False) date = models.DateField(default=now, null=False) class Meta: unique_together=(('fk_item', 'date'),) class Item(BaseModel): item_class = models.CharField(max_length=40, null=False) name = models.CharField(max_length=80, unique=True, null=False) Bit of code that gets run everytime a user logs in: for i in Item.objects.all(): try: latest_ir = ItemReport.objects.create(fk_item=i) print('Created Item Report!') except IntegrityError as e: print('ItemReport for {} for today already exists!'.format(i.name)) print('Created ItemReports!\n') -

How to test a custom field in Django 1.11.1
I've create a custom field in Django class MyField(models.CharField): description = "My awesome field" # ... I want to create a unit-test in which I make a temporary/ephemeral model that uses the field. My goal is to test that the functions like to_python, from_db_value, and validate, are implemented correctly from the view of an actual Model. I also don't want to have the Model included in the production database. I've looked up a few different means of doing this and they do not work: https://www.kurup.org/blog/2014/07/21/django-test-models https://stackoverflow.com/a/503435/2097917 https://blog.bixly.com/bixly-how-to-dynamically-adding-models-for-testing-in-django http://www.akshayshah.org/post/testing-django-fields/ These all seem to be outdated. I would like to be able to define the model within an tests.py file (i.e. projectroot/myapp/tests.py) and somehow have the setUp add the model to the database: class MyModelTest(models.Model): myField = MyField() class MyFieldTestCase(TestCase): def setUp(): # ... do something funky to create the table def test_foo(self): myModel = MyModel.objects.create(myField="something") self.assertEqual(myModel.myField, "something") -
Django ORM: exclude does not return expected result

Django Pagination won't sort second page
I'm using Django pagination, and everything is working fine except only one page is sorted. What I have tried: if request.method == 'POST': if request.POST.get('sort_by') == 'price': products_list = Product.objects.filter(category = category).order_by('price') selected_sort_price = "selected" elif request.POST.get('sort_by') == 'name': products_list = Product.objects.filter(category = category).order_by('name') selected_sort_name = "selected" elif request.POST.get('sort_by') == 'date': products_list = Product.objects.filter(category = category).order_by('-id') selected_sort_date = "selected" show=request.POST.get('show', 5) else: products_list=Product.objects.filter(category = category).order_by('-id') ... page = request.GET.get('page', 1) paginator = Paginator(products_list, show) try: products = paginator.page(page) except PageNotAnInteger: products = paginator.page(1) except EmptyPage: products = paginator.page(paginator.num_pages) The above only works if there is post call, if no post call, then it is sorted by date of creation. So if a user wants to sort by price, he will select price from a dropdown menu, and onchange, form will be submitted and objects sorted accordingly. The problem is, when the user goes to second page, then everything goes back to default, because no post calls are made, and the previous post data isn't retained. What can I do to make the sorting apply to all pages? Looking for some direction, -
Django: Convert form data into 'clean url'
Let's say I have the following form: <form id="search-form" class="form-horizontal" method="GET" action="/results/" role="form"> <input type="text" class="form-control" id="query" name="query"> <button type="submit" form="search-form" class="btn btn-primary"> <span class="glyphicon glyphicon-search" aria-hidden="true"></span> </button> </form> Currently, when the form is submitted, the url contains the query as a parameter, like so: www.<my-domain>.com/results?query=<some-query>. However, for SEO purposes, I want to convert this to a 'clean url', which would look more like this: www.<my-domain>.com/results/<some-query>. I've made the following modifications to my urls.py: urlpatterns = [ ... url(r'^results/(?P<query>[a-zA-Z ]+)$', views.ResultsView.as_view(), name="results"), ... ] So I should be able to grab the query value in my ResultsView like this: class ResultsView(TemplateView): def dispatch(self, request, *args, **kwargs): query = kwargs.get('query') How can I submit the form so it'll match with the corresponding url pattern? I've tried fiddling with the form action passing the input id to it, like this: action="/results/query/", but obviously, it thinks query is a literal string, and doesn't replace it with the value of the input. -

What program to use to add drag and drop functionality within a webpage
I'm looking for guidance on where to begin looking for a way to add drag-and-drop functionality within a web page. I know very little about web page development, so any insight is appreciated. What I am wanting to build is a web page that will have objects (e.g. image thumbnails) in a side pane that you can drag and drop into the main window to lay out how you want. In my case it will be in a structure like a binary tree where each image can be dropped in as a parent or child of the existing nodes. Where should I begin looking for a program that will allow this type of functionality? I have experience with Python, so I was hoping something like Django might do the trick, but since I know so little about web design, I really don't know if that is the right place to begin.
