Django Email Token (URL with token for a specific task)
I am working on a Django Project for a Real Estate website. I am trying to find a mechanism so the user can delete a listing (Row in the Database) directly by clicking on a URL link sent to his email. In the normal cases to delete a listing you are required to sign-in, however I am looking to find a way to create a unqiue URL (tokenized) so the user can do it directly from the email. Something similar to how the password reset tokens work but this for a specific task. Any Advices? Thanks, -
How to handle multiple multiple user types?
I'm working on a RESTful Django app that requires two types of users: regular and privileged users. Both users will have different ways to authenticate into the app: 1) Regular users: will authenticate with phone number and password 2) Privileged users: will authenticate with email and password What is a good strategy to handle this type of authentication system? Is there any way to dynamically authenticate using different methods (phone number and email) based on the type of user logging in? -

Using Delete request in Django outside of a form
I am trying to create a simple todo list app that uses POST to post data into the data base and a 'x' (\u00D7) to delete the todo. The code is as following: Views.py def delete(self, request, id): print(request.DELETE) self.model.objects.get(pk=request.delete['pk']).delete() return render(request, self.template_name, {'object_list':self.model.objects.all()}) Models.py class TodoDB(models.Model): todos = models.CharField(max_length=1000) day = models.CharField(max_length=10) def __str__(self): return str(self.todos) HTML and JS <ul class="list-group list-group-flush" id="list-group"> {%for item in object_list%} <li class="list-group-item">{{item.todos}}</li> {%endfor%} </ul> for (var i = 0; i < close.length; i++) { close[i].onclick = function() { var li = this.parentElement; li.style.display = "none"; $.ajax({ type: 'DELETE', url: "{%url 'todo_list'%}", data:{'pk':pk}, success: function(data){ alert("Success!"); }, error: function(){ alert("Error!

How to Return Value of Radio Button
I realize this should be a simple question, but I can't seem to get it to work and I've been googling for about an hour. I have a set of radio buttons defined in my HTML code here: <h6>Axis Filter</h6> {% csrf_token %} {% for radio in form.axis_filter %} <div class="radio-inline"> {{radio}} </div> {% endfor %} And in my forms.py file here: TIME_FILTER = [ ('years','Years'), ('quarters','Quarters') ] axis_filter= forms.CharField(label = 'axis_filter',widget=forms.RadioSelect(choices=TIME_FILTER),initial = 'years') Now I'm trying to get the selected value in my views.py using this: request.GET.get('axis_filter',None) I've also tried: request.POST.get('axis_filter',None) Each time I go to print the value however I get a value of 'none'. Does anyone have any suggestions? -
supervisor exiting with ENOENT
I am attempting to deploy a Django web application for the first time using NGINIX, Gunicorn and Supervisor on Digital Ocean Ubuntu 16.04 server. I am following the this linked tutorial. I am having a trouble configuring Supervisor.

rest api - Abort object creation in serializer create method
I'm wondering whether serializer create method is a good place for aborting object(model) creation. Let consider following code: class TestSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Test fields = ('url', ...) def create(self, validated_data): if everything_is_ok: return super().create(validated_data) else: #if something is wrong with data abort object creation and rise exception that will led to 400 or sth ??? From my perspective it looks ok, because I'm using many serializers and here I have code only related to that particular one. Nevertheless I'm not sure if this is correct way (maybe create method of ModelViewSet would be better?) If serializer create method is ok, how should I do it properly (raise exception or rather return 400 Response directly) Thank you in advance -
Safe to replace my domain name on my Django application?
Will I face any repercussions for replacing the domain name on my Django application? It's running on Ubuntu 16.04 with Nginx/Gunicorn. Apart from ALLOWED_HOSTS in my settings.py, the other locations I would replace the domain is my Nginx conf file and also my Digital Ocean nameservers. A possible concern I have is that I've secured my previous domain with certbot, so I'm not sure what will happen when I remove that domain and put in the new one, as there are certbot files configured only for that domain. -

Touch Feedback on custom video player in React
I am working on a React project which allows a user to tap on videos. While it didn't take too long to make it register the tap, creating animations for it is a lot trickier. As a place holder, when a part of the screen is tapped it creates a simple CSS circle appears with the center being the pixel that was tapped. Now, I want to make it look smoother, more like one of these: https://tympanus.net/Development/ClickEffects/ However, these seem to only work on static buttons. All the other solutions I've found had their own hitches; another that seemed interesting turned out to be a plain animation as a series of PNGs which seems pretty inefficient. I didn't try React's TouchableFeedbackNative because it only works on Android. This looked promising, but I don't understand if I'll be able to use it, and I don't want to pay $25 to find out. Does anyone have any suggestions for reusable and (ideally) modifiable animations for this kind of application? I'm happy with using plain CSS animations, but I really would love to avoid making a complicated one from scratch. -

Show python data on the web
So I'm an absolute beginner with python and want to make a website that's shows data from google spreadsheets in html. I'm using gspread and I'm able to get the data from the spreadsheet. The goal is to get working hours from people and display it to them. Ideally you could also input your name into the script so you can only see your own times. Currently I'm stuck on how to display the data and get the input from the user, preferably with html. My code: import gspread from oauth2client.service_account import ServiceAccountCredentials from datetime import date scope = ['https://spreadsheets.google.com/feeds'] creds = ServiceAccountCredentials.from_json_keyfile_name('credentials.json', scope) gc = gspread.authorize(creds) sh = gc.open("rooster") weekNumber = date.today().isocalendar()[1] weekWorksheet = sh.get_worksheet(weekNumber-1) employee_name = input("naam:") cell = weekWorksheet.find(employee_name) row_number = cell.row count = 2 while count <= 8: date = weekWorksheet.cell(1, count).value value = weekWorksheet.cell(row_number, count).value print(date, ": ", value) count += 1 -

How to upload and deploy django cookiecutter project, with docker, to heroku?
I am developing an app with django cookiecutter (with docker and heroku setup) and have come so far as to deploying it. This is my first ever project, so no prior experience with django, docker or heroku. I've read up on it at cookiecutter docs, heroku and a little on the docker website but I still don't how to deploy. I have downloaded the heroki cli , have set up app on heroku with my own domain and a postgres db and I am planning on getting hobby tier to get the automated certificate. All environment variables are set in the .env file and are set in the heroku config vars in my app at heoku. So everything should be alright as far as code and settings. I am also using git as version control. Am I supposed to upload the whole project (code, settings, docker files etc) to heroku with git or by some other means? I saw there was an option to deploy the project with docker deploys aswell at herokus website. What option is the correct one? I was thinking initially that I would just upload the project through git and run docker-compose -f production.yml up (in … -

OAuth2: Resource owner workflow
The python-social-auth is a fantastic library for integrating oauth2 backend with web application (in my case it is django).So now it is possible to login into my django app with social oauth2 services. However, I'd like the application to act as a resource owner as well. If another application already having a token should be able to call into my django application (XHR Request). The django application should behave as a resource owner. It should use introspect (oauth2 token introspection) the token to validate the it and give access to its resource. How can I customize python-social-auth (social-auth-app-django to be specific) to allow this workflow? The backend should be aware of the token in the request supplied, and should be able to skip login by supplying the token directly to a stage where we can fetch user data from token. This can be achieved by doing the token validation in the application view and redirect to either social login or to resource view. However, my intention is to modify the social-auth pipeline to achieve this so that the User model implemented in social-auth can be effectively used to store user data to backend. -

PyCharm Unresolved reference error Django. Python not recognizing Django
I have just installed Django 2.0, python 3.6.4, and PyCharm 2017 on mac OSX 10.12.6, everything works fine except for the fact that PyCharm is not recognizing Django at all. With any reference to Django, I get an "unresolved reference 'django'" error. It's obviously something I have not set up in the IDE because project runs perfectly. I am new to Mac OS, so maybe there is a path variable I need to set somewhere? When I installed everything I just downloaded python3 and pip installed django IN A VIRTUALENV. I don't know if that will help. I also tried to set the package interpreter in file->default settings->project interpreter. I may have been doing it wrong. In the project interpreter, I tried to add new local and typed in the path of my environment/bin/python but no luck. I even tried installing Django in PyCharm from available packages...nothing. Thanks in advance. -
django joins with many to many relationship
I've looked at multiple answers to similar questions on how to do a join over django models with a many to many relationship but none seem to work, could someone please help.

Working With Multiple Settings
I try to add multiple settings for my django project. Separate settings for devserver and production. For this I removed my settings.py file and the new file structure would look like this: mysite/ |-- mysite/ | |-- __init__.py | |-- settings/ | | |-- __init__.py | | |-- base.py | | |-- development.py | | |-- production.py | |-- urls.py | +-- wsgi.py +-- manage.py I filled in base.py, development.py, production.py and replaced the path to the root of the project at base.py BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) to ==> BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__)))) And it working good at my local server when I start python manage.py runserver --settings=mysite.settings.development but when I do the same settings in production I get Internal server error. My server works for Nginx and Uwsgi. -
