How to return data from a table in a Django template
I am trying to display data from a website in HTML. I have created a class called Video in models.py as follows: class Video(models.Model): filename = models.CharField("File Name", max_length=100) title = models.CharField("Video Title", max_length=250) The database is migrated and I am able to insert data into it using a Django form. I have checked and there is data in the database. I have the following code in my HTML template file, but the page is empty when it is displayed, and is showing no data. {% for video in Video %} <div class="row"> <div class="col-md-3"> <a href="{{ video.filename }}">{{ video.title }}</a> </div> </div> {% endfor %} Why isn't this displaying any data in the rendered HTML page? Edit: This is the relevant code from the view: def listvideos(request): """Renders the listvideos page.""" assert isinstance(request, HttpRequest) return render( request, 'app/listvideos.html', ) -
Understanding django's logging
I am a bit confused on how django is handling the logging. I have this setting for loggers in my settings: Logging settings LOGGING = { ... 'handlers': { 'console': { 'class': 'logging.StreamHandler', 'formatter': 'verbose', }, 'file': { 'level': 'DEBUG', 'class': 'logging.handlers.RotatingFileHandler', 'filename': LOG_BASE_DIRECTORY + '/django.log', 'maxBytes': LOGFILE_SIZE, 'backupCount': LOGFILE_COUNT, 'formatter': 'verbose' }, 'mail_admins': { 'level': 'ERROR', #'filters': ['require_debug_false'], 'class': 'django.utils.log.AdminEmailHandler' } }, 'loggers': { 'django': { 'handlers': ['file','mail_admins'], 'level': 'INFO', 'propagate': True, }, 'app1': { 'handlers': ['file','mail_admins'], 'level': 'DEBUG', 'propagate': True, }, ... }, } As one can see, I have 2 handlers defined for django and app logs, file and mail_admins. The log level for file is debug. Hence I assume all logs which are debug and above shall use this handler. The level for mail_admins is error. The problem that I am seeing though is that in case of 500 errors while email handler runs and sends the mail there is no logging on the file. -

MySql copy data from production to development DB keeping FK references
I am trying to figure out a way to copy data from the production DB(I'll call it prod DB from now on) into the development(I'll call it dev DB from now on). My system is: MySQL Python - Django(if it is any help) The sittuation is like that: assume I have all the tables, and even the rows needed for me from the prod DB the tables have FK refs between them. the PK on every table is self inc. I need to keep data in the dev DB, meaning my mission is to "merge" the data from prod to dev. I've read about mysql dump and not sure it will work since the pk and the fk connection will be all wrong(correct me if I am wrong), So I've been thinking about implementing it on my own, but just not sure about how to preserve the fk connection since after the export of data from prod it will be with the PK of the prod and they will all change when inserted to dev. so far my best idea is to use python and save a mapping of old key to new key but that is a messy way … -

Complex aggregation in Django
Using Django rest framework 3.x and Django 1.1.10. I have a model that represents users. When I list all the users by accessing /users/ endpoint in DRF the list has to include some more data that is related to users via another model, called Owner. Each Item has an Owner and Owners have Users. I made an extra property on the User model and it just returns a JSON array of the data. This is something that I can't change, because it is a requirement on the front-end. I have to return a total number of items that are related to each user and there are three different counts to perform to get the data. I need to get multiple count()'s of items on the same model but with different conditions. Doing these separately is easy, two are trivial and the last one is more complicated: Item.objects.filter(owner__user=self).count() Item.objects.filter(owner__user=self, published=True).count() Item.objects.filter(Q(history__action__name='argle') | Q(history__action__name='bargle'), history__since__lte=now, history__until__gte=now, owner__user=self).count() The problem is because this is run for every user and there are many of them. In the end this generates more than 300 DB queries and I would like to bring these to a minimum. So far I've came up with this: Item.objects.filter(owner__user=self)\ .aggregate(published=Count('published'), … -
when refreshing I got 404 not found (nginx)
My website URL is www.pm0603.com and everything works fine. But when I got into a detailed page or like http://www.pm0603.com/detail/113448 and hit refresh button(Or try to access that resources directly), then I got 404 not found error message. The front-end part is not done by me and I don't know exactly what the problem is. I am using Django for the back-end. And the refresh works without any problem in local env. I just guess it would be related to my nginx configuration. Or is it a cache problem? Below is my nginx configuration. server { listen 4567; server_name localhost api.pm0603.com pm0603-dev.ap-northeast-2.elasticbeanstalk.com; charset utf-8; client_max_body_size 128M; location /media/ { alias /srv/app/django_app/media/; } location /static/ { alias /srv/app/static_root/; } location / { uwsgi_pass unix:///tmp/app.sock; include uwsgi_params; }} server { listen 4567; server_name front.localhost pm0603.com www.pm0603.com; charset utf-8; client_max_body_size 128M; location / { alias /srv/please/; } gzip on; gzip_comp_level 2; gzip_proxied any; gzip_min_length 1000; gzip_disable "MSIE [1-6]\." gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;} As you can see, I have two servers, one is for the api and the other for serving static files.

Django Rest Framework: How to enable swagger docs for function based views
I went through Django REST Swagger 2.1.2 documentation. When I tried with class based views, it was working fine. But i did not find any reference on how to enable swagger for function based views as shown below: @api_view(['GET', 'POST']) def app_info(request): ... return response Most of my views.py is filled with function based views, just like above. Any help on how to enable the same will greatly appreciated. Thanks! I am using Django: 1.8; Django REST Swagger: 2.1.2; DRF: 3.6.2 -

Architecture inquiry for chatbot embedded python web application
I am new to programming and would like to ask for help structuring my project. I apologize ahead of time if I use a word incorrectly. I would like to build a python based web application. In place of the banner, I want to embed a chatbot written in python. I downloaded django and set up the provided application on my localhost http://127.0.0.1:8000/ I have a python script I wrote from scratch that I would like to use. I am not sure of my next steps having no prior experience. My goal would be to create a webpage with HTMl/CSS (web responsive) and my guess would be to have a DIV tag linked to the python script. Question: What term should I google so I can learn more about linking/embed/? python scripts to web apps? -

Shopify App Development that supports multiple platforms For eg. Shopify, Bigcommerce etc

How to initialize Django ModelForms on an entire queryset?
I am building an ad manager software, and I want to use django's ModelForm system to load an entire queryset of Ad objects so that users can alter fields in an already running/existing ad. I want to do this preferably in an alternative way to the modelformset_factory method. For example, if a user has a single Ad model you could simply call that instance and load the instance into a modelForm instance called AdForm so that they can edit the ad's properties: ad_instance = Ad.objects.get(pk=1) ad_form = AdForm(instance=ad_instance) So what about if the user has 20 active ads running? How can a queryset of 20 ad instances be loaded into their respective AdForms? Thanks -
In django-rest-auth, the password reset confirm URL doesn't work--is it missing arguments?
If you look at urlpatterns in django.contrib.auth.urls, the password_reset_confirm URL takes uidb64 and token params, which makes sense--when clicked on, this will identify the user resetting the password. However, django-rest-auth's rest_password_reset_confirm URL doesn't take any arguments: it just goes to password/reset/confirm/. How can it work? I get the following 500 error when submitting my email to reset my password, and I'm not surprised--the error makes sense: NoReverseMatch: Reverse for 'password_reset_confirm' with arguments '()' and keyword arguments '{u'uidb64': 'NA', u'token': u'4lj-65cd7b4219c9206126b4'}' not found. What I don't understand is it seems like such a basic thing that I must be doing something wrong--otherwise it seems like everyone using django-rest-auth would get this error because the arguments are clearly missing in the URL definition. Has anyone else experienced it and if so, did you update the URL to fix it? -

Pubnub always times out in Django app
I'm building a Django app to listen to a Pubnub feed and store the messages in a database. I create a pubnub listener in my app's apps.py's AppConfig's ready() method. Upon launching my app on Heroku, I get the really unhelpful error 2017-04-26T02:17:50.038060+00:00 heroku[web.1]: Error R12 (Exit timeout) -> At least one process failed to exit within 30 seconds of SIGTERM 2017-04-26T02:17:50.038060+00:00 heroku[web.1]: Stopping remaining processes with SIGKILL 2017-04-26T02:17:50.134619+00:00 heroku[web.1]: Process exited with status 137 I suspect django wants to clean up the AppConfig process and is getting upset that there is a pubnub object hanging around in there. Is that the problem? How do I fix it? I also see that (at least implicitly by example) Heroku recommends using the twisted interface. Is it bad that I'm not? Here's the relevant code: I created a mypubnub.py based on Pubnub's hello world example: from pubnub.pubnub import PubNub from pubnub.pnconfiguration import PNConfiguration from pubnub.callbacks import SubscribeCallback class MySubscribeCallback(SubscribeCallback): def presence(self, pubnub, presence): pass def status(self, pubnub, status): pass def message(self, pubnub, message): pass # I'll actually do the storage here later def create_pubnub(): pnconf = PNConfiguration() pnconf.subscribe_key = 'sub-c-blargyblargblarg' pnconf.publish_key = 'pub-c-blargyblargblarg' pubnub = PubNub(pnconf) pubnub.add_listener(MySubscribeCallback()) pubnub.subscribe().channels('achannel').execute() return pubnub I instantiate … -

My plugins definitions: from cms.plugin_base import CMSPluginBase from cms.plugin_pool import plugin_pool from django.utils.translation import ugettext_lazy as _ from .models import FaqPluginModel class FaqRowPlugin(CMSPluginBase): name = u'Faq Row' module = _("Fundbox") render_template = "faq_row.html" cache = False allow_children = True class FaqColumnPlugin(CMSPluginBase): name = u'Faq Column' module = _("Fundbox") render_template = "faq_column.html" cache = False allow_children = True require_parent = True class FaqPlugin(CMSPluginBase): name = u'Faq' module = _("Fundbox") model = FaqPluginModel render_template = "faq.html" cache = False plugin_pool.register_plugin(FaqRowPlugin) # register the plugin plugin_pool.register_plugin(FaqColumnPlugin) # register the plugin plugin_pool.register_plugin(FaqPlugin) # register the plugin -
Passing POST data from form into GET method to generate graph

I have the following urls set up. urls.py urlpatterns=[ url(r'^$',views.DisplayView, name='DisplayView'), url(r'^api/data/$', views.get_data, name='api-data'), url(r'^display/api/chart/data/$', views.ChartData.as_view()), url(r'^logs/', views.LogDisplay, name='Display-Logs'), ] In order to achieve this, I have added a form in my Display.html file above the code for ChartJs as follows.
