docker healthcheck shows not found in django
I added health check to my docker file: HEALTHCHECK --interval=1m --timeout=5s --retries=2 --start-period=10s \ CMD wget -qO- http://localhost:8070/healthcheck || exit 1 In my project main urls.py file I added entry: url(r'^healthcheck/', lambda r: HttpResponse()) The project is activated and deployed, so I can understand the healthcheck is valid, however - I keep getting: 2017-12-17 13:25:27,891 WARNING base 51 140551932685128 Not Found: /healthcheck written to the logs (once a minute). The log entry is added also when I run the wget from inside the server. Is it an issue with the healthcheck syntax, the django entry set up or the wget in docker? Please assist. thanks. -
iOS not playing html5 videos
I build a lan video server using Django. And I use the video tag to play videos so no extra players are needed to be installed. The videos play quite well in other platforms like windows or android. But it doesn’t work on my iPhone no matter the size or format of the video file. Moreover, when I use wireshark to analyze the data packages. I found out that the data is transferred correctly at the beginning, but the client closed the socket connection immediately . It’s quite bizarre. Can anyone help me figure out what’s going wrong here.Any suggestions will be helpful, Ps: I edited it on my phone, so sorry for the terrible format. -

signup url is not shown when using login form in other template
I am using django allauth for user registration part. I need to use login template also in checkout template if user is anonymous.

OR filter on MultipleChoices with django-filter
I have a form field with choices like [1, 2, 3, 4+], that 4+ means greater than equal and multiple choices can be selected. I want to do the filter using django-filter. I could do the filter for [1, 2, 3], but I don't know how to or it with gte=4. both the following work for filtering [1,2,3]: class NumberInFilter(django_filters.BaseInFilter, django_filters.NumberFilter): pass class PlanFilter(FilterSet): obj = django_filters.NumberInFilter(name='object', lookup_expr='in') class Meta: model = Plan fields= ['object',] or choices= ( (1,1), (2,2), (3,3), ) class PlanFilter(FilterSet): obj = django_filters.MultipleChoiceFilter(name='object', choices=choices) ...

Use one class based view for both List and Retrieve Rest API
I currently have two different class based views for detailing a specific object and for listing all objects: class StatusList(ListAPIView): permission_classes = (IsAuthenticated,) serializer_class = serializers.StatusSerializer def get_queryset(self): queryset = helperfunctions.getObjects(self.request.user, models.Status) return queryset class StatusDetail(RetrieveAPIView): permission_classes = (IsAuthenticated,) serializer_class = serializers.StatusSerializer def get_queryset(self): queryset = helperfunctions.getObjects(self.request.user, models.Status) return queryset Note that helperfunctions.getObjects() simply returns the objects that share the same establishment with the user, so that they can't see statuses that they shouldn't. What I want to know is whether there's an option to use only one class based view for both StatusDetail and StatusList, which would automatically know that when it gets a pk in the get request it returns the appropriate object, and when it doesn't, it should return the whole list of objects. Thanks for any help :) -
django - how to modify bcrypt or how to see its version?
I am building a website for a game server and they use bcrypt, so I do, but their hashes start with $2a$12$ which I know that isn't secure, and my hashes start with bcrypt_sha256$ if using bcrypt with sha256 or bcrypt$ if using only bcrypt.

nested for loop to display hierarchical data
I need to display a very simplified Gantt view in a project management app. For this I have a hierarchy of milestones, work-packages and tasks in my database. If I do an oversimplified datastructure of data = [ [ 'milestone', ['segment','segment'], [] ], ['milestone', ['segment'], ['task','task','task'] ], ['milestone', ['segment'], [] ] ] And use a code in my template like below, the display is correct. <table class="table"> <thead> <tr> <th></th> <th></th> </tr> </thead> <tbody> {% for x, y, z in data %} <tr > <td style="color:red;">{{ x }}</td> </tr> {% for yy in y %} <tr> <td style="background-color: lightgrey; padding-left: 20px;">{{ yy }}</td> </tr> {% for zz in z %} <tr> <td style="background-color: grey; padding-left: 40px;">{{ zz }}</td> </tr> {% endfor %} {% endfor %} {% endfor %} </tbody> </table> Now if I want to get realistic data structure with more work-packages(segments) summarising tasks, this solution does not work. See my data structure 'approach' to be more realistic x_new = [ [ 'milestone', ['segment','segment'], [] ], ['milestone', ['segment', ['task','task','task'], 'segment', 'segment', ['task'] ] ], ['milestone', ['segment'], [] ] ] Running this structure, I simply get the task hierarchy be displayed as yet another segment (sound logical).

Creating a "Yelp" like app as Python programmer
I am a hobby data scientist that has mostly been working in Python; scraping data, managing a Postgresql database and writing Jupiter notebook and python data cleaning and machine learning models. I now want to host my own web page where I can offer my data and created insights in a visual way. First objective is to have one page with an interactive map, and then markers that indicate POIs with additional data being offered to user through clicking on a point (through a pop-up bubble but also an area to the side of the map being dynamically updated to show details about selected marker). Basically a Yelp app, with their map feature. What is the best framework or language to do something like this? In my research I have seen django, plotly dash, bookeh, leaflet, react JavaScript etc. What I'm worried about it to pick something to start learning and then 3 months later I realize I don't have flexibility to add a functionality or visualization. I'm in it here to learn, so happy to learn a new language/framework as long as it will help me also down the road to build in more functionality into my website. -

In need of suggestions regarding creating a authorization structure
In my Django project, depending on the groups my users are in and other factors, I need my users to only be able to access some things or the information they get from the database to be limited depending on their access level. there is also a hierarchy on some of the access levels. Now this affects my model managers, views and my templates. Therefore, if I don't define a proper structure, it will be very troublesome in the future. I was wondering if there is a suitable pattern and how I would be able to create a decent Django project for this ( access levels are object level). I would be grateful if somebody could help me. -
