How to use Django template context processor and form together?
I am a newbie to Django. In a project I have to take inputs for multiple models in Django using forms. For every model I have written functions (in views.py) and its corresponding Django template (in template folder). Such as,my Add Teacher function is, def add_teacher(request): form = TeacherForm() if request.method=="POST": form = TeacherForm(request.POST) if form.is_valid(): form.save(commit=True) return index(request) else: print(form.errors) return render(request,"billing/add_teacher.html",{"form":form}) And billing/add_teacher.html template is, <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Add Teacher</title> </head> <body> <h1>Add a Discipline</h1> <div> <form id="teacher_form" method="post" action="/billing/add_teacher/"> {% csrf_token %} {% for hidden in form.hidden_fields %} {{ hidden }} {% endfor %} {% for field in form.visible_fields %} {{ field.errors }} {{ field.help_text }} {{ field }} {% endfor %} <input type="submit" name="submit" value="Add Teacher"/> </form> </div> </body> </html> Now, I want to use a template for all of my functions.Such as, I want to use this template for all functions with the help of Django template context processor. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>{{ title }}</title> </head> <body> <h1>{{ h1 }}</h1> <div> <form id={{ form_id }} method="post" action="{{ action }}"> {% csrf_token %} {% for hidden in form.hidden_fields %} {{ hidden }} {% endfor %} {% for field … -
Django URL complicated patterns and paths
I'm trying to generated nested url paths. So far I could only generate 1 level urls. When I try second level urls it doesn't get called anymore, it still only shows the first level url although the address bar on the browser does direct to the second level url. Is this possible or do I need to create a new app? urls.py from django.conf.urls import url, include from django.views.generic import ListView, DetailView, TemplateView from dashboard.models import IPARate,PCPRate from dashboard import views urlpatterns = [ url(r'^$', views.index, name='index'), url(r'^medicare/', ListView.as_view(queryset=IPARate.objects.all().order_by("id"), template_name='dashboard/medicare.html')), url(r'^medicare/medicarepcp/$', ListView.as_view(queryset=PCPRate.objects.all().order_by("id"), template_name='dashboard/medicarepcp.html')), url(r'^medicare/', views.medicaid, name='medicare'), url(r'^medicare/medicarepcp/$', views.medicarepcp, name='medicarepcp'), ] -
jQuery keyup event is activated multiple times, doubling every time its triggered
I added an auto-completing search bar to my website. It queries the database for elements that start with the entered string every time the user types a new character. It works fine, however every time the user adds another character or does any keyboard event like backspace it doubles the event activation. 1,2,4,8,16, etc.. times. How could I make it so that it doesn't accumulate event triggers and only triggers .keyup() one time per keyboard event? Here's the HTML code: <form> <div class="nav-item"> <input class="search-query form-control" placeholder="Items" type="text" name="items" value="" id="id1" /> </div> </form> <hr> <div id="id2"> </div> And here's the jQuery code: $(document).ready(function() { $('#id1').keyup(function(){ var query = $(this).val(); $.get('/url/', {items: query}, function(data){ $('#id2').html(data); }); }); -
django create gif and store in DB
I'm receiving files from an input via a POST request. I'd like to take to those create a GIF from them and store it directly in a sqlite database. I have found various ways in python to create GIFs out of images and save them to the file system like the one here VALID_EXTENSIONS = ('png', 'jpg') def createGIF(data, duration=0.2): images = [] for d in data: images.append(imageio.imread(d)) output_file = 'Gif-%s.gif' % datetime.datetime.now().strftime('%Y-%M-%d-%H-%M-%S') imageio.mimsave(output_file, images, duration=duration) but I was not able to find a way of creating the GIF and either store it into variable or save it into the DB directly. Is there any way of creating a GIF and not have to save it to disk first before putting it in a DB? -

Python web application installer packages?
Has anyone ever made an installer package for a Flask or Django (or other WSGI framework) application that lays down the code, virtualenv, configures the WSGI server (Gunicorn or uWSGI for example)? I've tried Googling the topic but I only find documentation about installing the frameworks themselves or deploying the applications to cloud services like AWS and Heroku. I know that all of the above could be scripted, but I'm interested in building actual installer packages for different platforms that get the WSGI app up and running and leaves the other needed components (such as database, cache, proxy, etc.) up to the administrator. Are there existing examples of this someone could point me to? Does anyone have suggestions on where to start for learning how to create these packages? -
Django DRY - how to simplify similar views using same template?
Please note: Just to make clear '[app_name]' is a placeholder for the actual app name. Not Django substitution code. Just imagine it says 'Stuff' instead of [app_name], if it's confusing. My question: How do I make this more DRY? There is a lot of code repetition, and there must be a way of unifying some of it. If you do answer, I would be really grateful if you write out explicitly what and why. As a lot of answers assume quite a bit of knowledge and I am trying into good habits in Django coding style and practice. Thank you for your time.

Gmail open tracking, set cookie with Django
I'm working on a simple app to embed a transparent pixel into emails being sent out manually with Gmail and then cookie the user. I'm inserting this <img> into the email: <img height="1" src="https://example.net/pixel.png?guid=1234" style="visibility:" width="1"> The intent is that when the email is opened it should request the image from example.net/pixel.png The Django app with an endpoint of pixel.png has this view: def set_cookie(request): PIXEL_GIF_DATA = "R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data = base64.b64decode(PIXEL_GIF_DATA) response = HttpResponse(data, content_type='image/gif') response.set_cookie('some_cookie_name', 'some_cookie_value') return response If I visit `example.net/pixel.png?guid=1234' it's setting the cookie appropriately, so we're good there. The only issue I'm running into is that when the email is opened the request is not being made out to my server. As the recipient if I go into the developer tools and watch the network requests I'm not seeing the request being made to mysite.net However, if I view the original email, down in the footer I can see that my <img> tag is included. If I try using an external image like static.example.net/images/sometest123.png the image does come through and is visible. -

These are all run with docker-compose up. However, I need to have the RabbitMQ IP address for celery.py in different container. Looking through Google, docker-machine ip <container> should be the solution. However, docker-machine only works for running container, AFAIK.

It does not enter edit mode, like it is disabled, but ONLY for him: He is not trying locally, he is trying live, so there is not a difference between Wagtail versions He cannot edit using his credentials, or any other credentials He tried different browsers and different computers I tried with his credentials and I am able to edit Any idea of what could be causing this?

From my API views.py class FriendManageAPIView(CreateAPIView): permission_classes = (permissions.IsAuthenticated,) serializer_class = FriendManageSerializer def post(self, request, *args, **kwargs): if request.data['action'] == 'add_friend': return self.create(request, *args, **kwargs) From my API serializers.py class FriendManageSerializer(serializers.ModelSerializer): to_user = serializers.CharField(max_length=150) def create(self, validated_data): friendship_ret = None try: request = self.context.get("request") if request and hasattr(request, "user"): user = request.user user_model = get_user_model() to_user = user_model.objects.get(username=request.data['to_user']) friendship_ret = Friend.objects.create( from_user=user, # The sender to_user=to_user, # The recipient ) friendship_ret.save() except (AlreadyFriendsError, user_model.DoesNotExist, AssertionError): print("EXCEPTION FriendManageSerializer.create()") return friendship_ret How should I really handle this case? What should I be returning when the object is not valid?
