Django template doesn't load
Am following the Django Website's tutorial, currently on Pt3(https://docs.djangoproject.com/en/1.11/intro/tutorial03/) Tutorial states: "This code should create a bulleted-list containing the “What’s up” question from Tutorial 2.

Sync App-Backend user table with wordpress login
I programmed a Backend for an app. In the Backend is of course the login/registration endpoint. The problem is that my client had the new idea of synchronizing his Wordpress Blog with the app. And now he wants that when an user registers himself in the App, then he can log in the Wordpress and when an user registers himself in the Wordpress Blog, he can log in the App. My problem is that I'm not specialized either in Wordpress nor in PHP. I was watching the wp-login.php file, but didn't find a good result. I'm thinking of using the Backend Endpoint with Wordpress, I can guess that Wordpress could work as a client. Then I could use the same Login-Backend-Function with the App and with Wordpress and it should work. I was reading this kind of post in Internet, but is not that way, I don't want to register an user in Wordpress from the app, but the other way, I would like to register an user in the App or in Wordpress and log him in the App or Wordpress, but using the Django Endpoints of the Backend. I did't think that it would be so complicated. Maybe … -
object that was saved with commit=False, still saved
I have a very big model, with steps form. So I decided on each page get previous object and update his attributes in form. In first form I do: def save(self, commit=False): obj = super(FirstForm, self).save(commit=False) obj.id = 999999999 self.request.session['obj'] = pickle.dumps(obj) self.request.session.save() return obj Id is requires for mtm. So I set default one. Then on last step in view I do: obj = self.request.session.get('obj') obj = pickle.loads(obj) obj.id = None # remove temporary id obj.save() But Django save two objects. One normal object and one empty with id 999999999 . Why ? I tried do: obj = super(FirstForm, self).save(commit=False) obj.id = 999999999 self.request.session['obj'] = pickle.dumps(obj) self.request.session.save() obj.delete() But it didn't help. -
how does django-rest-framework- javascript web token work with django to auth users?

data labels stacked diagram d3
I am creating charts with D3 in Django and I would like to include data labels in one of my stacked bar diagrams. This is the code for the data labels that I have so far: bars.append("text") .text(function(d) { return d3.format(".2s")(d.y1-d.y0); }) .attr("x", function(d) { return x(d.y1)+(x(d.y0) - x(d.y1))/2; }) .attr("y", y.rangeBand()/3) .style("fill", '#ffffff'); I found this in a similar thread but it does not seem to work for my case. The whole code for the diagram is here: https://www.dropbox.com/s/y5v5z7ism39ibyo/stacked%20diagram%20code.rtf?dl=0 And this is the result: https://www.dropbox.com/s/w26ui3pqkwdkr3k/stacked%20bar%20chart.png?dl=0 As you can see, it displays "NaN" instead of the data. I would like to have 3 data labels per chart for each part of the bars. The data that I'm using is in csv format and looks like this: country,1 year prevalence ,3 year prevalence ,5 year prevalence Albania,4.3,11.9,18.2 ... Any suggestions? Thanks in advance! -

custom user auth in django how to hook up
So the django docs are great but I am confused, it would be great to have a mentor right now. I want to create a custom user model and authentication system the user model will have -name -password -email -JWT (javascript web token) a permissions and a venue (place of entertainment) will be connected to this user model via a many to many relation via an association table. Here is the problem, even with the docs I am confused how I override the current out of box implementation for authorization. Additionally I'd like to use https://github.com/GetBlimp/django-rest-framework-jwt for the token auth but I have no idea how to hook it up. I guess I am looking for a walk through. -
django-filter | updating search results without refreshing the page
I'm using django-filter to allow users to search and filter through my blog posts. I have a search form with the method=GET and a couple of filters set up. It works by refreshing the entire page. I don't want that. I want it to refresh only the div that contains my results. Doing some research I found out I may need to use AJAX for that. Problem is, I don't know JS. I'll provide snippets of my code to show you what I would need.

How to run Flask function that triggers on user's action and add content to the page?
The idea is that user push the button and Flask should add some content on the page. In my case python and Flask is not an aleatory choice, because python make a lot of backdoor work (that for example js can't). And perfectly it should be just one page without redirection on another page. So my question is: 1) How to get the moment when user push the button and run the function I want 2) How to make this function add some generated content on the page without reloading. -

Is there a Django way of comparing the results of a test to a fixture?
I'm trying to understand fixtures and unit tests in Django. I can successfully load a fixture and use the data in my unit test. What I want to do is compare the results of the test to a second fixture, fixture_2, which represents how the data should look. Here's a step-by-step of what I am talking about: Import fixture_1, generating the initial test data. Run the test on the data, changing it. Somehow compare the results of the test to fixture_2. Is there a way to do step 3? Should I somehow overwrite the test database with fixture_2 and do the assertions from there, or is there a way of comparing the test database to a fixture? -

How to make a website work with Django development server?
I understand that this is never to be done. But I have a situation where I need to get something done real quick. I have to do a website where may be 200 people would register for an event. I need to present a simple registration form. Very basic functionality, register and view list of registrants. Very few hits. It would be live for about a month or so. I know a little bit of Django which can allow me to put together this thing quickly. However, I have only worked with the Django development server. My problem is setting up Apache to work with Django. I understand that, for Django, I need mod_wsgi installed. I have a VPS but mod_wsgi is not installed. I have asked my hosting provider to install it for me. Even if I can get mod_wsgi installed, it appears that it may take me some time to configure it and it may take a while. I have the following questions. Can I run this website on the Django development server? Will it hold up for very light traffic? If I do, how do I get traffic to go from port 80 to the development server … -
trouble using python requests to POST to django 1.8 server
I tried using session and grabbing the cookie. s = requests.Session() s.get(myurl) csrf = s.cookies['csrftoken'] The get had status_code 200 as expected. Then I first tried just a post on the session hoping that the session would do magic. (yeah I know better) r = s.post(myurl, json=mydata) which gives a status_code of 405. And yes, before I forget I have the django settings CSRF_HEADER_NAME='HTTP_X_CSRFToken' CORS_ORIGIN_ALLOW_ALL = True and my view function is marked with @csrf-exempt as well. The view function is known to accept post from my Angular frontend as long as I have 'X-CSRFToken=csrf' where csrf is as in the above setting. So I tried r = s.post(myurl, json=mydata, headers={'X-CSRFToken':csrf}) as well with the same result of 405. I read that it might help to set the referer to the url so I tried that as well. r = s.post(myurl, json=mydata, headers={'X-CSRFToken':csrf, 'Referrer: url}) and still got 405. So what is the correct way to make this work? -

django-allauth mutli step signup form
I'm using pydanny/coockiecutter-django for a custom project, and I needed to build a custom multi-step signup for customers. django-allauth is a custom authentication tool inside cookiecutter so after some researching and reading the docs I found out how to customize allauth SignupForm and allauth-SignupView so it will fit my needs, but I have some problems, but please bare with me it's a long question. This custom signup needs to use some custom fields for state, zip-code and phonenumber. For this I'm using django-localflavor and for phonenumber-field I'm using django-phonenumber-field. Process of extending signup in django-allauth is a bit different. You can not define normal ModelForm field with class Meta rather you need to do it like this. This is two-step custom signup form. from django import forms from allauth.account.forms import SignupForm from localflavor.us.forms import USStateSelect, USPSSelect from ..models import User class CompanySignupStepOneForm(SignupForm): """ TODO: Custom Signup. :returns: TODO """ company_name = forms.CharField(max_length=225, required=True, strip=True) company_street_address = forms.CharField(max_length=225, required=True, strip=True) city = forms.CharField(max_length=225, required=True, strip=True) state = USStateSelect() zip_code = USPSSelect() def save(self, request): user = super(CompanySignupStepOneForm, self).save(request) company_user = User( step_one=user, company_name=self.cleaned_data.get('company_name'), company_street_address=self.cleaned_data.get('company_street_address'), city=self.cleaned_data.get('city') ) company_user.save() return company_user.step_one Step-two custom Signup Form: from django import forms from allauth.account.forms import SignupForm …
