Integration of Django based plug-ins into wagtail
Can anyone describe the general actions when integrating addons or widgets built originally for django in to wagtail? For a novice user, it's hard to understand exactly how to edit the code so that it works in wagtail cms.

How to extract values from log file simultaneously while a process is running in django view
To update my progress bar, i need to compute the percentage of progress of a process running in my django view, to do this; i have to retrieve some values simultaneously from a log file generated while this one is running so that i can compute the percetage equivalent to 0/5000, 19/5000... as shown in the picture. I'm new to django and programming in general. How can I do that please in a function in my django views.py? or if there is a way to it with javascript will be also good solution. Thank you in advance. The log file which is generated looks like this: -
celery received tasks and execute it step by step (Singleton)

Django referencing Javascript variable in server side template code
I have a page that adds textboxes dynamically, and on the dynamically added text boxes, I want to access the relevant context variable. To do so, I somehow need to use the 'i' variable inside the javascript code/template code to reference it's value in the context. Here's my javascript code where I need to use 'i' as an index for a context list: <script> var i = 2 function add_field() { var table = document.getElementById("tbl_location").getElementsByTagName('tbody')[0]; var input_name = document.createElement("th") input_name.appendChild(document.createTextNode("S/N " + i)) var input_tb = document.createElement("td") var input = document.createElement('input'); input.setAttribute("name", "sn" + i); {% if curr_sn.i %} input.setAttribute("value", {{ curr_sn.i }}); {% endif %} input_tb.appendChild(input) var input_row = document.createElement("tr") input_row.appendChild(input_name) input_row.appendChild(input_tb) table.appendChild(input_row); i++; } The specific lines are: {% if curr_sn.i %} input.setAttribute("value", {{ curr_sn.i }}); {% endif %} Where 'i' is a javascript veriable, and curr_sn is a list the python code gives as a context. The html part where I need to use 'i': {% for i in max_board_list %} {% if curr_sn.i %} <tr> <th>S/N {{ i }}</th> <td><input type="text" name="sn{{ i }}" value="{{ curr_sn.i }}"></td> </tr> {% endif %} {% endfor %} Here 'i' is generated by a for loop, but I still need … -

Ordering a Django queryset based on other list with ids and scores
I'm a bit mentally stuck at something, that seems really simple at first glance. I'm grabbing a list of ids to be selected and scores to sort them based on. My current solution is the following: ids = [1, 2, 3, 4, 5] items = Item.objects.filter(pk__in=ids) Now I need to add a score based ordering somehow so I'll build the following list: scores = [ {'id': 1, 'score': 15}, {'id': 2, 'score': 7}, {'id': 3, 'score': 17}, {'id': 4, 'score': 11}, {'id': 5, 'score': 9}, ] ids = [score['id'] for score in scores] items = Item.objects.filter(pk__in=ids) So far so good - but how do I actually add the scores as some sort of aggregate and sort the queryset based on them? -
Django - saving partially filled form to prevent data loss
I have a form which takes quite a long time for the user to fill. I would like to set up a feature (some AJAX) which saves the currently filled values every N seconds so that the user does not lose their data in case of connection problems/misclick/internal server error. Sure, I can do this on my own by saving the user and filled values in some serialized form (say JSON) into a manually created table in the database. But I wonder, can Django do this for me? I hope it makes sense at least a bit and thanks in advance for your ideas! -
Django register api with two User profile models
I am trying to create user, where User model has two User profiles, e.g. Teacher and Student. At the time of creating user, I want to create User instance in Teacher or Student profile also.

So, if user_type is student, I need to create User instance for the StudentProfile as well(a new row in student profile table) -

DRF Response content-type set to None during tests
I'm using Django Rest Framework (version 3.6.2) to create REST API. I've defined my viewset that inherits from GenericViewSet and have overriden retrieve method to implement custom behaviour. class FooViewSet(viewsets.GenericViewSet): serializer_class = FooSerializer def retrieve(self, request, *args, **kwargs): ... serializer = self.get_serializer(data) return Response(serializer.data) I want to have BrowsableAPI while accessing this endpoint from the browser and receive json response when accessing this endpoint e.g. from the code. I've configured DRF with the following settings: REST_FRAMEWORK = { 'DEFAULT_RENDERER_CLASSES': ( 'rest_framework.renderers.JSONRenderer', 'rest_framework.renderers.BrowsableAPIRenderer', ), 'TEST_REQUEST_RENDERER_CLASSES': ( 'rest_framework.renderers.JSONRenderer', ), 'TEST_REQUEST_DEFAULT_FORMAT':'json' } Everything works as expected, I can access the browsable API from the browser and when making request with the Postman tool I get json response. Unfortunately, I can't achieve the same result during tests. class GetFooDetailViewTest(APITestCase): def test_get_should_return_json(self): response = self.client.get(self.VIEW_URL) self.assertEqual(response.content_type, "application/json") I expect the response to have content_type set to application/json (this is the header that I can see in the responses from browser and Postman). But this test fails - response.content_type is set to None. While debugging this test, I've discovered that response._headers dictionary looks like this { 'vary': ('Vary', 'Cookie'), 'x-frame-options': ('X-Frame-Options', 'SAMEORIGIN'), 'content-type': ('Content-Type', 'application/json'), 'allow': ('Allow', 'GET, PUT, DELETE, OPTIONS') } So it seems like … -
Can I change Django's "Starting development server" link?

Custom model validation for many to many field in django
Hi there I have a model like this: class Team(models.Model): owner = models.ForeignKey(User) members = models.ManyToManyField(User) Now One Owner can have multiple teams but a particular member will only belong to one team.

How can I do this validation? -

How to put default Django Login in Bootstrap Modal?
I created a login template and imported the default url routing following MDN's guide, but now I want to put that into a modal to not have the user go through so many redirects. I realize variants of this question have been asked, but I read through so many and am still really confused. I have the template as configured in the MDN link, but if I try taking the content and pasting it directly into my modal in another template, it does not show the fields since they depend on Django template variables. I believe the default url config is from django.contrib.auth import views as auth_views url(r'^accounts/login/$', auth_views.LoginView.as_view()), but I'm also pretty confused about it since it was built in. All I had to do to implement the login form was write the login template and add url(r'^accounts/', include('django.contrib.auth.urls')), to my project urls, so it is pretty daunting to create the modal login from here. Do I have to write a new LoginView class as well? Should I be using something like django-crispy-forms? I currently just post the data, but will I need to use AJAX instead for when a field is incorrect? Any guidance is so appreciated. Much … -
Heroku keeps deleting online added data
I deployed a django project on heroku. For media storage, I used aws s3 storage. The project has an admin interface, from which I can add data. The problem is that, after some time, the data I added online on heroku is lost. Only the original data (that was in my databse before deploying on heroku ) is conserved. I'm using heroku only for test, but still this is bothering. Is there's a way to overcome this behaviour? I though about storing data also in aws s3 but I don't know how to do it. -
get_template_names(self) doesn't work in TemplateView
I'm trying to use PDFView from django-pdfkit. The problem is that I don't have one template. Instead I have 4 templates. The template chosen depends on request.GET parameter.

This is from urls.py: url(r'^render/doklad/', views.Test.as_view(), name="doklad_to_pdf"), This is a PDFView (in case it helps): class PDFView(TemplateView): #: Set to change the filename of the PDF. filename = None #: Set to default the PDF display to inline. inline = False #: Set pdfkit options dict. pdfkit_options = None def get(self, request, *args, **kwargs): """ Return a HTTPResponse either of a PDF file or HTML. :rtype: HttpResponse """ if 'html' in request.GET: # Output HTML content = self.render_html(*args, **kwargs) return HttpResponse(content) else: # Output PDF content = self.render_pdf(*args, **kwargs) response = HttpResponse(content, content_type='application/pdf') if (not self.inline or 'download' in request.GET) and 'inline' not in request.GET: …
