Best way to refresh graph without page refresh (Python Django, ajax)
A bit of a general question - I am looking for ways to refresh a graph on a Django page based on user choices. The page has a graph, a few drop boxes where you can select parameters and a refresh button. Currently, I can capture the selections via ajax to my Django view and generate new data from database for the graph. I now need to feed that newly-generated data back into the graph and refresh it without a page refresh. Could anyone recommend the best methods of doing this? -
Convert template layout into crispy forms layout
I am currently trying to convert a django template that I have been using into a django-crispy-forms Layout. I am having some problems doing this as I want to do it on an inline formset that is currently being made with django-extra-views. I have attempted to do this but have not got the desired result so far, and the docs on this subject aren't exceedingly helpful (in my opinion). I have had no problems with changing my other form layouts to use crispy forms just the formsets. Currently, my template looks like this: <div class="col-md-8 col-lg-8"> <form role="form" method="post"> {% csrf_token %} {{ form|crispy }} <div id="formset"> <div class="alert alert-info" role="alert"> Field names <strong>must</strong> be unique. </div> {{ field_inline.management_form }} {{ field_inline.non_form_errors }} {% for form in field_inline.forms %} {{ form.non_form_errors }} <div id="{{ field_inline.prefix }}-forms"> <div class="form-inline"> {% for field in form.visible_fields %} <div class="form-group"> <label for="{{ field.id_for_label }}" class="form-control-label m-2 requiredField"> {{ field.label }} <span class="asteriskField">*</span> </label> {{ field|add_class:"form-control" }} {{ field.errors }} </div> {% endfor %} {% for hidden in form.hidden_fields %} {{ hidden }} {% endfor %} </div> </div> {% endfor %} </div> <hr> <button class="btn btn-primary pull-right ml-1" type="submit">{% trans "Next" %}</button> <a class="btn btn-light … -

Clarity on Setting up Docker containers for django projects?
I'm experimenting with docker and have some basic hands-on with it. I would like to know how to structure the containers to scale in a better way. Auth Container - Using Auth0 for Authentication only. With JWT for authentication Profile Container- A python app to store user profile along with MongoDB as a database. I prefer keeping this in a separate container because it will not be used much as the other services. Blog Container- This is another python app that allows users to write/edit articles and uses the same MongoDB as the profile container. My Question is how two different python apps share the authentication from the auth container. I have developed similar monolithic apps with Django, but as a single project. I would like to do the same but both the profile and blog as different projects itself. What kind of Structure should I follow to implement such projects? -
Django form is still full after sign up
I have an app in django 1.11. Below is the view with the form where the user can sign up for the event, after saving he gets a message about the details - on the same page, at the same url. But, after saving the form is completed and after pressing F5 the next saving is performed. How can I avoid this? I think something with the form_valid method is wrong. class EventDetailView(DetailView, CreateView): model = models.Event form_class = forms.ParticipantForm context_object_name = 'event' template_name = 'events/event_detail.html' def get_success_url(self): return reverse('events:detail', kwargs={'slug': self.kwargs['slug'], 'pk': self.kwargs['pk']}) def form_valid(self, form): self.object = form.save() context = self.get_context_data() context['registered_event'] = context['event'] return self.render_to_response(context) -
Why shouldn't you use PHP within Django? [on hold]
I have seen in several websites people saying it is a really bad idea to mix PHP scripts within a server running Django. Plus, it is (apparently) a quite hard thing to do. Still, I don't understand why. Although I get that both run on server side I do not understand why you shouldn't use some PHP if there's anything you think would work better than python (or you just feel like using it). So, can/should you use PHP in a python server using Django? How and why? Thank you <3 -

Showing sensor reading in a django website
I want to design a web based application for showing sound sensor readings, collected from an Arduino based setup (and also show some analysis results). For making my arduino setup work I had developed a python program named 'ard_sensor_project.py' which collects readings and store in .csv file and create a graph. Now I want to display the readings generated in a django website. For that I have imported 'ard_sensor_project.py' in views.py of my django site and called a method to print the sensor reading at real time. But on running the program, it seems that though the reading collecting module has started, the site has not started yet and I can neither see the web page nor any reading. Is there any way such that I can show the readings on the django site? Here is my ard_sensor_project.py import matplotlib.pyplot as plt from datetime import datetime #necessary declarations sr = serial.Serial("COM6",9600) #self declared methods def getsensordata(): st = list(str(sr.readline(),'utf-8')) return int(str(''.join(st[:]))) def storedata(fname,val1,val2): #stores data in a .csv file, will update if required def plotgraph(): #method for plotting data in a matplotlib graph, will update if required #codes as part of main execution + function calls print("------Reading collection starts now------") … -

Little explantion of behaviour of web application with and without cookies. Sharing this so others might benefit from this very simple example
from django.shortcuts import render count = 0 behaviour of the code without cookies is below everytime a new connection is made by restarting the server count resets. def index(request): global count count += 1 context={'count':count} return render(request,'index.html',context=context) To avoid the above behaviour use any of the below 2 implementation server side cookies implementation and client side cookies. Server side cookies implementation def index(request): visited = request.session.get('visited',0) request.session['visited'] = visited+1 return render(request,'index.html',context={'visited':visited}) Client side cookies implementation. Not considered as a safe practice as server would definitely be more secure than your personal computer. Always try to use this approach def index(request): context = {} visited = 0 resopnse = render(request,'index.html',{'visited':visited}) if 'visited' in request.COOKIES: visited = int(request.COOKIES['visited']) visited += 1 response = render(request,'index.html',{'visited':visited}) response.set_cookie('visited',visited) return response
