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------") … -
Django - prefetch query - Cannot find set on object, invalid parameter
Im trying to prefetch a mapping table based on a mapping table. How does prefetch link tables together? as the foreign key for circuits is the same in both tables, im not sure why they wouldn't join? circuits = SiteCircuits.objects.all() \ .exclude(circuit__decommissioned=True) \ .select_related('site') \ .select_related('circuit') \ .prefetch_related('circuitnotes_set') \ .prefetch_related('circuit__circuit_type') \ .prefetch_related('circuit__circuitfiles') \ .prefetch_related('circuit__provider') \ .prefetch_related('circuit__service_contacts') \ .prefetch_related('circuit__circuit_type') models are as such: class SiteCircuits(models.Model): site = models.ForeignKey(SiteData, on_delete=models.CASCADE) circuit = models.ForeignKey(Circuits, on_delete=models.CASCADE) site_count = models.IntegerField(verbose_name="How many sites circuit is used at?", blank=True, null=True) active_link = models.BooleanField(default=False, verbose_name="Active Link?") class Meta: verbose_name = "Site Circuits" verbose_name_plural = "Site Circuits" unique_together = ('site', 'circuit',) class CircuitNotes(models.Model): circuit = models.ForeignKey(Circuits, on_delete=models.CASCADE) notes = models.ForeignKey(Notes, on_delete=models.CASCADE) class Meta: verbose_name = "Circuit Notes" verbose_name_plural = "Circuit Notes " unique_together = ('circuit', 'notes',) Ive also tried adding a QuerySet filter to match the circuit id's but the variable circuit_id doesnt exist, im not sure if I can filter based on an object id in this manner? circuits = SiteCircuits.objects.all() \ .exclude(circuit__decommissioned=True) \ .select_related('site') \ .select_related('circuit') \ .prefetch_related( Prefetch( 'circuitnotes_set', queryset=CircuitNotes.objects.filter(circuit_id=circuit_id) ) ) \ .prefetch_related('circuit__circuit_type') \ .prefetch_related('circuit__circuitfiles') \ .prefetch_related('circuit__provider') \ .prefetch_related('circuit__service_contacts') \ .prefetch_related('circuit__circuit_type') -

How to persist range control value on page reload
I have a Django application in which I want to persist range control value on page reload. At the moment on every page reload its value is getting reset to the default. I know HTTP is a stateless protocol and consider every request as new, So we have to find some way to store range value in a cookie or something like that and then retrieve it from clients machine on page reload somewhat like this. Can anybody show me the right direction, thanks in advance. <div class="slidecontainer"> <input type="range" min="1" max="100" value="50" class="slider" name="myRange" id="myRange"> </div> -
django rest framework: allow any user can edit any data (remove object_permission)
I am using django rest framwork's "viewsets.ModelViewSet" to list,create,update and delete table rows. For the following Tasks model it works fine. But it only allows to list,create,update and delete of self entries (ie, resource owner) or the user should be superuser. I want to make this api to other users can view and modify the delete regardless of the creator. In simple words, all authenticated user can view/edit anyones entries.

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 -
Could anyone tell me about the lazy loading and transaction of django?
background like this: data = User.objects.get(pk=1) if data.age > 20: with transaction.atomic(): data.age -=2 data.save() I want to know ,if many process do the code at the same time,it like that,each process would get the data at the same time without transaction,for example ,age is 30. then,one process do the next,make age-2=28 and save. Then the next process do,when it do data.age -=2 ,the data get by data. age ,would be 18 or 20? If it is 20,did it means,the transaction add the wrong place? Or it means , the transaction would not work,because the transaction would add to the data do select lines,and can change and save.but the transaction add with out select line? second question: if I do like this: data = User.objects.get(pk=1) with transaction.atomic(): if data.age > 20: data.age -=2 data.save() this demo,add the transaction before the data.age > 20. For the lazy loading,the sql lines would do when I use it ,such as data.age > 20. But when it readly do sql lines,the transction had add before. So, I want to know,did this demo would add transaction on sql lines? thanks a lot,nice people. -
Override widget templates in Django
I have defined templates in settings.py as following: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ os.path.join(BASE_DIR, 'static/html/templates'), ], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] and tree for html/templates is this: when I edit for e.g. change_form.html , the changes are reflected, even when I change any template inside includes that also takes effect. However, when I edit templates inside widgets directory, no changes are reflected. If I edit that inside /django/contrib/admin/templates/admin/widgets that takes effect. How am I supposed to override widgets? -

Setting SECURE_HSTS_SECONDS can irreversibly break your site?
I'm wanting to implement SECURE_HSTS_SECONDS to my Django settings for extra security - however the warning from the Django docs is making me abit scared so I want some clarification. Here is what is says: SECURE_HSTS_SECONDS Default: 0 If set to a non-zero integer value, the SecurityMiddleware sets the HTTP Strict Transport Security header on all responses that do not already have it. Warning: Setting this incorrectly can irreversibly (for some time) break your site. Read the HTTP Strict Transport Security documentation first. What has to happen for it to "break my site"? I read the HTTP Strict Transport Security documentation first and it didn't make it any clearer. -
Is it possible to automate extraction and inlining of critical css with Django using gulp-critical or webpack?
I'm new to programming and I've recently built a website using Django + Bootstrap 4 and was trying to improve my pagespeed on Google SEO Google Page Speed Insights Page Speed Insights suggested using Critical and this led me to discover front-end tools such as Gulp and Webpack. I've read on tutorials on how to use Critical with Webpack here but the problem my django templates are fragmented to keep things organized using {% block content %}. This in turn hinders using the HTML Webpack Plugin + Critical combination to extract the critical css and inline it. Any suggestions or is my only option to manually extract my site's critical css? Hoping for a step-by-step answer or maybe a link to a website to guide me as I am relatively new to all this. Thanks in advance! -

I know it is a simple answer but for some reason I cant figure it out. here is the forms.py file: # all model imports related to this project from models import * class LoginForm(forms.Form): username = forms.CharField(max_length=20) password = forms.CharField(max_length=20, widget=forms.PasswordInput) here is the models.py file: from django.db import models from django.contrib.auth.models import User, UserManager from localflavor.us.models import USStateField, USZipCodeField # the following is the users profile model class Profile(models.Model): # users basic info user = models.ForeignKey(User, on_delete=models.CASCADE) f_name = models.CharField(max_length=25, default='first') l_name = models.CharField(max_length=25, default='last') bio = models.CharField(max_length=220, default='bio') # users location street = models.CharField(max_length=200, default='street address') city = models.CharField(max_length=100, default='city') state = USStateField(default='CA') zip_code = USZipCodeField(default=12345) # users other profile info phone = models.IntegerField(default="000-ooo-oooo") dob … -
django-wiki: how to list all articles under root article
I am a newbie in Django and am currently building a site. I have downloaded django-wiki ver 0.4a3 to have a wiki app for my site. Everything works fine, out-of-the-box. But instead of showing the root article as the main page, how can I show a list of all articles under the root article, so users can just click on any child article to open up that article? At the moment, users have to click a menu option to browse up one level or to browse at the current level to have a listing of all articles at that given level. I find this rather tedious. I rather have an "Windows Explorer tree-and-branch-like" navigation, e.g., root |_child 1 | |_child 1.1 | |_child 1.2 | |_child 2 | |_child 2.1 | |_child 2.1.1 | |_child 3 Please note I am asking how to get a list all of articles under the root article, not how to create a template to implement the tree-and-branch articles navigator. Once I know how to get a listing of all articles, I think I can implement the necessary HTML and CSS to have that kind of navigator. I appreciate any pointers. P.S. I have previously … -
Loop through items into Django 1.8 template
I have this method: def profile(request): parsedData = [] if request.method == 'POST': username = request.POST.get('user') req = requests.get('https://api.github.com/users/' + username + '/repos') jsonList = [] jsonList=req.json() userData = {} for data in jsonList: userData['html_url'] = data['html_url'] userData['created_at'] = data['created_at'] userData['updated_at'] = data['updated_at'] userData['forks_count'] = data['forks_count'] parsedData.append(userData) return render(request, 'app/profile.html', {'data': parsedData}) This code looks into an url like this githubtraining As You can see, the response contains lots of repositories, however, not every github user has more than 1 repo. Anyways, on my html view I have this: <div class="table-responsive"> <table class="table table-bordered table-hover table-striped tablesorter"> <thead> <tr> <th class="header"> Url <i class="icon-sort"></i></th> <th class="header"> Created at <i class="icon-sort"></i></th> <th class="header"> Updated at <i class="icon-sort"></i></th> <th class="header"> Forks count <i class="icon-sort"></i></th> </tr> </thead> <tbody> {% for key in data %} <tr> <td>{{ key.html_url }}</td> <td>{{ key.created_at }}</td> <td>{{ key.updated_at }}</td> <td>{{ key.forks_count }}</td> </tr> {% endfor %} </tbody> </table> </div> What happens then? Well, right now, if, for instance, I query the githubtraining user to see it's repos, it shows only the last one, on that and every other user, so, what am I doing wrong here? The loop is there, what am I missing?
