So I am creating my blog with Django and I am developing the notification system. I want when the user click the drop to mark all notifications as seen its working and every thing is working fine but when I add the Ajax the dropdown stop working but the Ajax works fine I tried changing the script position in HTML but nothing. Using bootstrap 3.3.7 locally jquery the ajax : <script> $(document).ready(function() { $("#n_d").click(function(event){ $.ajax({ type:"POST", url:"{% url 'seen' %}", success: function(){ document.getElementById("mcount").innerHTML = 0 } }); return false; }); }); </script> the dropdown (it's inside a navbar) {% if user.is_authenticated %} <li class="dropdown"> {% notifications request as notifications %} <a href="#" class="dropdown-toggle" id="n_d" onclick="return x=1" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"><i aria-hidden="true" class="fa fa-inbox "> <span class="label label-info" id="mcount">{% noticount request %}</span></i></a> <ul class="dropdown-menu"> {% load blog_tags %} {% for notification in notifications %} <li> <div class="col-md-3 col-sm-3 col-xs-3"><div class="notify-img"><img src="https://www.awn.com/sites/default/files/styles/userthumbnail_tiny/public/avatar92.jpg?itok=i7013HnC" alt=""></div></div> <div class="col-md-9 col-sm-9 col-xs-9 pd-l0"><a href="{% url 'detail' notification.post_pk %}">{{ notification.FromUser }}&nbsp;{{ notification.content }}</a></div> </li> {% endfor %} </ul> </li> {% endif %} the weird tags are Django stuff. -
Django widget template override does not search in the project template directory. How to fix?
I am attempting to override a built in widget template in Django 1.11. I seem to be doing everything that the docs say to do in this regard, but for the widget templates, Django is not looking in my project at all, and I get a TemplateDoesNotExist error. Here's what I have for the override: class MyFileWidget(widgets.FileInput): template_name = 'myapp/my_file_widget.html' The template is definitely there. If I pass the template to a render call, it finds it fine. Problem is an issue of paths. When calling render from a view, it checks the following: projectroot/templates/myapp/my_file_widget.html djangoroot/forms/templates/myapp/my_file_widget.html When it finds the template in my project, it renders it. This is NOT happening when I provide the template path in the class above. In that case, it does not check in my project templates, where the file actually exists, and begins checking in the django path, where it does not. Hence the error message. So I have no clue why this the loader would check my project templates on render calls, but then fail to do so when looking for the "template_name" of the widget override. Any ideas? -

Django: how to get list related ForeignKey records?
I am using Django v1.11. Here are 2 models: class Task(models.Model): title = models.CharField() class TaskUser(models.Model): task = models.ForeignKey(Task, related_name='task_user') user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='+') So, I want to get list of tasks and print in one column list of users that are related to this task. How to do that? The problem is tried a lot: select_related, prefetch_related('task_user') and so on.. but nothing works.

Removing unnecessary filters from URL django-filter
I have implemented a pretty standard use of Django-filter, and I noticed that when I submit my query, the URL populates not just with the filters I entered, but with blank values for every filter I did not as well. For example, when I fill out just the STATUS_CODE filter, and then search on my site, I get http://localhost:8888/request-log/?status_code=200&route=&time_sent_0=&time_sent_1=&python_error_msg=&s3_upload_failed=&s3_error_msg= Ideally, I would like the URL to only show fields that aren't blank. So, it would go to http://localhost:8888/request-log/?status_code=200 What is the best way to do this? -
Insert data to sqlite3 - python - django
I'm new to django framework. I parsed data from WebAPI server to dict: key is product buys and value is list that contains info about product. Code: def get_best_products(self): dict_of_items = {} for x in range (0, self.max_range): itemId = self.fresh_data.item[x].itemId itemTitle = self.fresh_data.item[x].itemTitle photoUrl = self._get_main_item_photo(x) itemPrice = self._get_item_price(x) dict_of_items[self.fresh_data.item[x].bidsCount] = [itemId, itemTitle, itemPrice, photoUrl] return self._sort_parsed_item_data(dict_of_items) def _sort_parsed_item_data(self, data): return OrderedDict(sorted(data.items(), reverse=True, key=lambda t: t[0])) So i have dict of sorted items by product buys with info as value.

Is there a standard way to mock Django models?
I have a model called Pdb: class Pdb(models.Model): id = models.TextField(primary_key=True) title = models.TextField() It is in a one-to-many relationship with the model Residue: class Residue(models.Model): id = models.TextField(primary_key=True) name = models.TextField() pdb = models.ForeignKey(Pdb) Unit tesing Pdb is fine: def test_can_create_pdb(self): pdb = Pdb(pk="1XXY", title="The PDB Title") pdb.save() self.assertEqual(Pdb.objects.all().count(), 1) retrieved_pdb = Pdb.objects.first() self.assertEqual(retrieved_pdb, pdb) When I unit test Residue I just want to use a mock Pdb object: def test_can_create_residue(self): pdb = Mock(Pdb) residue = Residue(pk="1RRRA1", name="VAL", pdb=mock_pdb) residue.save() But this fails because it needs some attribute called _state: AttributeError: Mock object has no attribute '_state' So I keep adding mock attributes to make it look like a real model, but eventually I get: django.db.utils.ConnectionDoesNotExist: The connection db doesn't exist I don't know how to mock the actual call to the database. Is there a standard way to do this? I really don't want to have to actually create a Pdb record in the test database because then the test won't be isolated. Is there an established best practices way to do this? Most of the SF and google results I get for this relate to mocking particular methods of a model. Any help would be appreciated. -
Django View function. Can't get a value from Dictionary, only full dictionary

How to have different serializers for read_only & write_only with the same name in DRF?
After you create a Django object in a CreateAPI of DRF, you get a status 201 created and the object is returned with the same serializer you used to create the Django object with. Wanted: on create: Serializer.comments = Textfield(write_only=True) and on created (201 status) Serializer.comments = a list of commments I know it's possible by overriding the CreateAPIView.create function. However, I'd like to know if it's possible by using write_only=True and read_only=True attributes to serializer fields. For now I think it's not possible because they both have the same name. I'd have liked to do something like this: class CreateEventSerializer(serializers.ModelSerializer): comments_readonly = serializers.SerializerMethodField(read_only=True, label='comments') class Meta: model = Event fields = ('id', 'comments', 'comments_readon) def __init__(self, *args, **kwargs): super(CreateEventSerializer, self).__init__(*args, **kwargs) self.fields['comments'].write_only = True def get_comments_readonly(self, obj): comments = obj.comments.replace('\r', '\n') return [x for x in comments.split('\n') if x != ''] But this way, the JSON that is returned still contains the key "comments_readonly" instead of the expected key "comments". Using latest DRF, 3.7.1 In other words: Is it possible to create a serializer field that behaves differently based on read and write? -
No JSON object could be decoded - Need to upload file to Django
I'm working on an existing Django app and need to be able to upload a file. I'm sending it a multi-part form so I can send a file and some fields, but the server responds back No JSON object could be decoded How can I allow my view to accept a multi-part form? My route function definition is simply: @api_view(['POST']) def upload(request, pk) print "hello" It doesn't get to hello, so somewhere in the magical box of Django this JSON error is occuring. Can anyone give me a clue where to look? I've checked our urls.py file and see nothing that would make this decision or interrupt a request and our init.py file is empty. runserver isn't even a file... I guess it's just more django magic.

Django POST request does not organize data as expected
So I have a form that I'm posting to a Django app. The field names are such as: field[section][name][attr] where section, name, etc. can have any number of values. When I attempt to access the data in the POST request these are the exact keys in the QueryDict, so to access the data I have to do something like request.POST.get('field[section][name][attr]'). Why doesn't Django create the hierarchy so I can do something like fields = request.POST.getlist('field') and then go deeper from there with something like for section, value in fields: for field_name, attributes in value: It seems I have to use regex's to process the form data. Am I missing something? -

How can I reverse django admin url with url parameters to prepopulate some fields?
I have Transaction app and Transaction model. Transaction model has foreign key to User model. I noticed that I can prepopulate some fields with data through GET parameters. For example to choose user for my transaction in admin form I can use this url: transactions/transaction/add/?user=1 It work fine, but I want to user reverse function to generate that kind of urls. Tried this: from django.urls import reverse reverse('admin:transactions_transaction_add', kwargs={'user': 1}) But got this error: Reverse for 'transactions_transaction_add' with arguments '()' and keyword arguments '{'user': 1}' not found. 1 pattern(s) tried: ['admin/transactions/transaction/add/$'] I made this work to use concatenate generated link: change_url = reverse( "admin:transactions_transaction_add", ) + "?user=" + str(obj.pk) But would be very kind to know if the more clear solution for this. Note that 'transactions/transaction/add/?user=1' works just fine if use it from browser, error appears for reverse function. Thanks! -
