One specific module shows import error while other modules are imported in venv python
I have installed Django in venv and then installed suntimes, suntime and astral (all latest versions) in the same venv. But only Django is getting imported, other 3 modules are showing import error. I have a Mac with default python 2.7 and I have installed python 3.6 from python website long time back. PATH variable is set to 3.6 via nano editor and I have been using alias for python = python3. Django works fine with the alias or without alias, but other 3 modules just don’t get imported no matter I remove the alias too. I have tried putting the site_packages folder from my venv directly into my project folder and then the modules work fine, but this is not the right way. When I did like this and removed alias, the modules work with python3 and not the default python 2.7. So I am guessing the problem is somewhere with my venv and not PATH, but then why would Django get imported even with venv or without venv and others just won’t? I have tried basic troubleshooting of restarting the Mac and recreating venv and reinstalling Django and other modules but I am still back to where i … -
Django rest framework custom renderer in testing response

Using absolute online location for Django templates
I am currently working on a django project, I have hosted it on heroku.And I don't really want to keep pushing to heroku unless really necessary, so i thought of pushing the templates to github , where i can change at ease and no extra zipping and host timer is needed.

How to pass a video return from JavaScript to python backend in Django view for OpenCV
I want to do certain tasks and the processes are as follows: 1. Access the camera of the user to get the video-frames from them. 2. Process the video frames from the backend code for facial recognition and some more tasks. 3. Return the processed frame back to the user. Initially, I had used cv2.VideoCapture(0) and it was simply triggering the camera of the system which was hosting the server, i.e. my personal laptop. So, I used JavaScript to trigger the camera of the user's system. The HTML and JS code is as follows: <div id="container"> <video autoplay="true" id="videoElement"> </video> </div> <script> var video = document.querySelector("#videoElement"); if (navigator.mediaDevices.getUserMedia) { navigator.mediaDevices.getUserMedia({ video: true }) .then(function (stream) { video.srcObject = stream; }) .catch(function (err0r) { console.log("Something went wrong!"); }); } </script> Now I want to get the video feed from the user and link it to the backend to process the video frames.

How to modify values in m2m field in form? (Django)
I have 2 models in my models.py. They are Doctor and Specialty: class Doctor(models.Model): name = CharField(max_length=255) specialties = ManyToManyField('Specialty', related_name='doctors') mc_id = CharField(max_length=255, unique=True) class Specialty(models.Model): name = CharField(max_length=255) mc_id = CharField(max_length=255, unique=True) def __str__(self): return self.name When i'm creating new Doctor instance via admin interface (change_form.html template) I see my Doctor model fields, which I should fill with data.

A I want is to see in this list not only specialty names, but also values of mc_id field of Specialty model, but it is not my case to make it at the expense of something like this: class Specialty(models.Model): name = CharField(max_length=255) mc_id = CharField(max_length=255, unique=True) def __str__(self): return self.name + '(' + self.mc_id + ')' I thought i could make it through overriding of formfield_for_manytomany() method in my admin model (associated with Doctor model) in admin.py: @admin.register(Doctor) class DoctorAdmin(admin.ModelAdmin): def formfield_for_manytomany(self, db_field, request, **kwargs): if db_field.name == "specialties": queryset = Specialty.objects.all() for specialty in queryset: specialty.name += '(' … -

django modal bootstrap Async with select list update
I am trying to implement a bootstrap modal on my django app that allows my user to create a new element that they can then pick in a select html list. I successfully implemented a way to generate a select list using selectize and querying for all the titles in my DB (function GetTitles). And I managed to create a new title through a modal using django bootstrap modal async (without re-direct - $("#title-modal").modalForm...) However, I now need to make sure that the new title created is added to the select list. Since the title is already in the db, i was thinking about calling the function GetTitles again upon submission of the modal. I tried to do so using the parameter addModalFormFunction: GetTitles but it's not really working...so I am definitely doing something wrong...right? <div id="title_div" style="margin-top: 20px;"> <label for="id_title" style="margin-bottom: 5px;" class="lead">Title</label><br/> <select class="" name="title" required="" id="id_title" multiple=""></select> </div> $(document).ready(function() { function GetTitles(){ $.ajax({ url: "{% url 'action:GetTitles' %}", type: 'GET', data: { csrfmiddlewaretoken: "{{ csrf_token }}", user:"{{ request.user.id }}", }, error: function(err) { console.log(err); }, success: function(options) { $('#id_title').selectize({ valueField: 'id', labelField: 'title_name', searchField: 'title_name', maxItems: 3, preload: true, options: options, create: true, plugins: ['remove_button'], create: function(input) … -
How to include related fields when serializing to geojson in django
I have two models. The first contains point data. The second is a ForeignKey back to the point model. How do I include fields from the second model when seralizing the first model? class Site(models.Model): ptgeom = models.PointField(srid=2953, blank=True, null=True) ... class File(models.Model): site = models.ForeignKey(Site, on_delete=models.PROTECT, blank=True, null=True) name = models.CharField(verbose_name='File', max_length=250, blank=True, null=True) ... In my view I build a queryset of the visible points and attempt to pass it back to the map: def file_points(request): ... q_set = Dmsesite.objects.filter(ptgeom__contained=geom) points_as_geojson = serialize('geojson', q_set, geometry_field='ptgeom') return JsonResponse(json.loads(points_as_geojson)) From this, I get a json of all the point records in q_set. I want this to include the File records as well. I have searched but am really lost. I have attempted .select_related(), but from the Site side the File model is not actually a related field. I attempted to follow this question: Specify fields of related model in Django GeoJSON serializer field and create the CustomSerializer, but I still didn't get any File records. Another possibility may be to somehow build a new queryset on the opposite side (File side) based on the current queryset (Site), but I'm not sure how I would go about this as I think … -

How to change seed packages versions when creating virtualenv?
I am running into an issue when deploying a django-rest-framework API to production. The addition of seed packages pip, setuptools and wheel upon virtualenv's creation causes my deployment to fail. It appears that the specific version of setuptools (59.1.1) used here prevents usage from Newlines (related to this issue) which are used in the description of django-hijack==2.10.1 and causes the following error. This behaviour has been reverted in the newer versions of setuptools (from 59.4.0). Thus I would like to pin the version of setuptools added in seed packages upon virtualenv creation to make sure my deployment succeeds but I have no idea if/where I can set added packages versions.

How to change dates when filtering a queryset in Django?
I want to display a list of all payments done by the company. But I want to be able to filter the dates, only showing payments for example: In the last 30 days In the last 90 days Between two specific dates Now, I know I can filter in my views between two dates, or before today for example. But how I can I do this using something like a dropdown or a Data chooser on the template? Something like this for reference. For reference, the payments model would be this: class Payment(models.Model): name = models.CharField(max_length=250) date = models.DateField(default=datetime.now) value = models.DecimalField(max_digits=10, decimal_places=2, validators=[MinValueValidator(0.00)]) -
