Display Django logs in templates
I'm working on a project with Python(3.6) and Django(1.10) in which I'm doing some execution in Django views.I'm printing some messages and other execution information in the console but I want to display this information inside the template which is going to be rendered after the completion of a request from Django views. Here's an example code from my Django views: # Start deployment # Setup istio on cluster service = discovery.build('container', 'v1beta1', http=views.getGoogleAuth(), cache_discovery=False) svc_req = service.projects().zones().clusters().get(projectId=deployment.project, zone=deployment.zone, clusterId=deployment.cluster) svc_res = svc_req.execute() print('Status is : {}'.format(svc_res['status'])) status = svc_res['status'] while status != 'RUNNING': svc_res = svc_req.execute() status = svc_res['status'] print('Current Status is : {}'.format(svc_res['status'])) print('Fetching Cluster configs ....') print(subprocess.call( 'gcloud container clusters get-credentials ' + deployment.cluster + ' --zone ' + deployment.zone + ' --project ' + deployment.project, shell=True)) print('Cluster is still Provisioning - Current Status is: {}'.format(status)) How can I display this log information inside Django template when the request has been completed. Help me, please! Thanks in advance! -

Let's say that I have links_ 'http://link/problem1', 'http://link/problem2' and 'http://link/problem3' In my django template I'm trying to link to a random link out of those three: So in my django template I have: <a href="http://link/problem" class="btn btn-success"> Some Text </a> Is there a way that I can have a numeric loop that would loop through numbers 1 to 3 and add those numbers to the 'http://link/problem' I have found a few examaples on how to make a numeric for loop in a django template but I dont know how to add those numbers to the link in an a tag. -
prefetch_related and Prefetch object issue, filtering thru reverse Foreign Key
I have 2 models, company and Product. class Product(Meta): company = models.ForeignKey(Company, related_name='products', on_delete=models.CASCADE) form the database I'm trying to get the Company data and the corresponding products. From the products I want to get only the name and to be ordered descending by updated_at, created_at. I'm working with Prefetch object and prefetch_related and definitively I have multiple misunderstandings how they work. def get_queryset(self): qs = Company.objects.prefetch_related( Prefetch('products', queryset=Product.objects.only('name').order_by('-updated_at', '-created_at'))).get() return qs The error that I receive is: get() returned more than one Company Because I closed the prefetch_related method/function with ))) : I thought get() will act over the Company object and get it using the pk/slug from the url(as get do by default in DetailView). Seems that is not the case. I'm already using 'products' the related name in the Prefetch object, why in queryset is necessary to tell again the model queryset=Product.objects.... ? I was looking at the following example in django documentation: Question.objects.prefetch_related(Prefetch('choice_set')).get().choice_set.all() If there is 'choice_set' in Prefetch object why is called at the end choice_set.all() ? Isn't Django attached to the quesryset in prefetch_related the products to the queryset (question.choice_set) ? I think my problem is that I don't understand the order of execution, … -
Django / Geodjango / Raster / geotiff: Problems with practice task
I greet you First, I apologize for my bad english. I can read English to some extent, but I can not write well. I hope you can help me. I got a practice task, which I can not get any further. The task is the following: Project Description The goal of the projects is to create a map view similar to the Google Maps, where user can see some imagery data captured by drones. User should be able to move around the map freely, as well as zoom in and zoom out to take a closer look at the captured imagery data. It is strongly desired that the served imagery data will support transparency while minimizing the file size and bandwidth usage. This does not have to be implemented, but solution ideas are welcomed. The raw imagery data will be provided as GeoTIFF files. Imagery visible on the map can be added by placing a file inside a directory that is read by the server. Project Delivery Method Project should be delivered as a Git repository with documentation required to setup and run the project. Requirements 1. Server implementation in Python 3.5+ 2. Project must be able to run on … -
Update Django Status Field Based On Real-time Status of Celery Task?
In my model, I have a status field with a default value of 'Processing'. In the Django admin interface, after user clicks 'Save' button, the form inputs are passed to a celery task that just sleeps for 30 seconds. After that 30 seconds, how do I: determine if the celery task was successful? update the model's status field from 'Processing' to the actual status (ex: Completed, Failed? models.py from django.db import models class Scorecard(models.Model): name = models.CharField(max_length=100, unique=True) status = models.CharField(max_length=20, default='Processing') def __str__(self): return self.name admin.py from django.contrib import admin from scorecards.models import Scorecard from scorecards.tasks import get_report class ScorecardAdmin(admin.ModelAdmin): list_display = ['name', 'status'] def save_model(self, request, obj, form, change): if form.is_valid(): data = form.cleaned_data name = data['name'] get_report.delay(name) super().save_model(request, obj, form, change) admin.site.register(Scorecard, ScorecardAdmin) tasks.py from __future__ import absolute_import, unicode_literals from celery import shared_task from time import sleep @shared_task def get_report(name): sleep(30) Real-time status of the celery task updating the status field every x time intervals would be nice, but for now I'm just really curious how to do this at all. -
Contact Us form on a Django Website not sending emails
I followed the instructions from the official documentation and another Stack Overflow post to get django-contact-form working on my django website. I need it to send an email. I tried setting up a debugging server through: python -m smtpd -n -c DebuggingServer localhost:1025 I have a HTML form working with Django on the site. When I click submit on the form, it gives me an acknowledgement that my message has been sent. However, I can't see anything on the Terminal output. In my settings.py, I have the following: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'localhost' EMAIL_PORT = 1025 EMAIL_HOST_USER = 'my email' EMAIL_HOST_PASSWORD = 'my password' I have also tried it with the SMTP settings for Zoho mail, which is the one that I am currently using. I am not getting any emails in my inbox or the others folder either. Another thing that I have tried is changing the settings so that the emails get stored in a tmp folder. I don't want to deploy the code on the site until I can test that it works properly. Any help will be appreciated. I'm not really sure what I'm missing. Let me know if any other files are needed from … -

Django View Usage
I'm still quite confused on when to use a View in django A view returns a webpage back or a HttpResponse. Suppose my website had a button "Get total" that adds up the numbers in a user-inputted checkbox To give this button functionality, what are the steps I would take? Would pressing the button call a URL, which would call a view, which would return a response? How would I "fetch" this response? I'm sorry this is vague, but I don't know what I need to search to be able to do the above using Django. Is this an example of REST? I want to create a form that can be processed by Django and then return a response to the user such as "Answer is correct", without refreshign the webpage. I am using django 1.11, I've been working with django for like a month now, and I"m starting to get better everyday (I can use models and all the similar stuff alright) but I'm stuck at this point forward -

How to Rehydrate React Components of Python App with Server-side Rendering
I'm using the python-react library to create a Django app with server-side rendering of react components. Although I've implemented basic rendering successfully, I've been unable to rehydrate the DOM - so React event handlers aren't working. Any thoughts on how to resolve? I've tried including a script tag with a webpack bundle. My code closely resembles an app the docs provided as a basic example; that app is available here: https://github.com/markfinger/python-react/tree/master/examples/basic_rendering. Please note that the example app uses Flask. -
Writing nested queries in Django
I am trying to write a nested query in Django. It is very simple to do in SQL, but with Django I am having some trouble deciding if I am doing it right or not. I have three models. Area, Location, and Measurement. Area class Area(models.Model): name = models.CharField(max_length=200) longitude = models.FloatField() latitude = models.FloatField() Location class Location(models.Model): name = models.CharField(max_length=200) altitude = models.IntegerField() area = models.ForeignKey(Area, on_delete=models.CASCADE) Measurement class Measurement(models.Model): value = models.FloatField() date = models.DateTimeField() location = models.ForeignKey(Location, on_delete=models.CASCADE) Inside Area, I need a function that will return the average of the measurements for this area. So basically, I need the average measurements of all locations for this area. Area can have many locations, but locations can have one area. In the Area Model, I made this function: def average_measurement(self): all_locations = self.location_set.all() return all_locations.measurement_set.all().aggregate(Avg('value')) This is my equivalent to writing a nested query in Django. I get all locations first and then find the average of all their measurements. Am I doing this correctly? On a side question, would this query be equivalent to doing something like this: avg = 0 locations = self.location_set.all() sum = 0 counter = 0 for l in locations: measurement = l.measurement_set.all() … -

How to store a DOMDocument (Node) object in Django?
Background I would like to store the text a user is highlighting when they click a button. I first get the Range from a user's selection with window.getSelection().getRangeAt(0). Given this [Range] object, I would like to be able to store some data in my Django server so that when another user visits my website, they can see what others highlighted. If you know the answer, stop reading here. The following are solutions I have considered. I am wondering how I could do this most efficiently. Possible Solutions: Creating a Node Field in Django. I am not extremely experienced in Django. However, I was wondering if it would be possible to write a custom Django Field which stores a Range or Field object. It would be ideal for the field to work like so: script.js function getSelectionRange() { return window.getSelection().getRangeAt(0); } $.post({ url: "http://127.0.0.1:8000/range/", data: { string_key: foo().toString(), ... range: getSelectionRange() }, processData: false }); views.py ... range = Range.objects.create(range=request.POST.get('range') ... or, with a field for Node objects: ... first_node = Node.objects.create(node=request.POST.get('first_node') end_node = Node.objects.create(node=request.POST.get('end_node') ... Would the ajax call work? Would string values be a Python str in my views.py using request.POST.get('string_key')? Reconstructing the Range object using its constructor: The … -

localhost:9200 shows elasticsearch version as 6.0.1 after reinstalling 5.0.1
Previously I tried using elasticsearch 6 with django-haystack 2.6.1 for full text searching. I came to know that haystack does not support elasticsearch v6 so I deleted it. The steps I did for deleting and reinstalling are rm -rf es/ (I copied the elasticsearch in this folder) I downloaded the elasticsearch 5.0.1 from official website mv Downloads/elasticsearch-5.0.1.tar.gz es/ tar -zxvf elasticsearch-5.0.1.tar.gz cd elasticsearch-5.0.1 ./bin/elasticsearch -d I then run the following command in the terminal curl -XGET 'http://localhost:9200' My configuration HAYSTACK_CONNECTIONS = { 'default': { 'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine', 'URL': 'http://127.0.0.1:9200/', 'INDEX_NAME': 'haystack_furnitures', }, } The tech I am using macos, django==1.11.6, django-haystack==2.6.1, elasticsearch==5.0.1 and elasticsearch in a system the same version -

However I've reached this point in the tutorial where it says to create a virtual environment. I thought virtual environments were only used for testing your application offline? Why do I need a virtual environment for my application running on a remote server? -
