Django - Forms - What does (?P\d+)/$ signify? Help please
I am new to django. I was creating forms in django with the help of an online tutorial. I didnot understand a line in the urls.py file. Can someone explain what exactly it means? from django.conf.urls import url from . import views from . views import BlogListView, BlogDetailView, BlogCreateView urlpatterns = [ url(r'^$', views.BlogListView.as_view(), name='post_list'), url(r'^post/(?P<pk>\d+)/$', BlogDetailView.as_view(), name='post-detail'), url(r'^post/new/$', BlogCreateView.as_view(), name='post_new'), url(r'^post/(?P<pk>\d+)/edit/$', BlogUpdateView.as_view(), name='post_edit'), ] I did not understand the following line: url(r'^post/(?P<pk>\d+)/$' What does (?P\d+)/$ signify? Help please -
Conditionally pass model decleration in Meta to django ModelForm
Is there a way to conditionally pass the model class to the meta in a model form before instantiation / the metaclass magic happens? I have a lot of "specification" fields that need to have update / create views and they all have the same fields excluded. Hence, I can just set excludes and the model form will do the rest for all of them. Thus, I only really need one form / one update form for all of this. It'd be exceedingly redundant to define update and create views for all of these... With this I can just use one update and one create view for all of them passing the form_class in my urls.py as BaseUpdate(form_class=MyBaseForm(ModelClass)) and BaseCreate(form_class=MyBaseForm(ModelClass)) -
Django gets all checkboxes values, checked or un-checked
Using Django's User model, I have the following template: {% for account in accounts %} <tr> <td> {{ account.username }} </td> <td> <input type=checkbox name=account value="{{ account.id }}" {% if account.is_active %}checked{% endif %}> </td> </tr> {% endfor %} which shows the status of each account and the user may update them. In the views: accounts = request.POST.getlist('account') # This will get only the `checked` ones for account in User.objects.filter(id__in=accounts): if account is checked: # Only hypothetical ... account.is_active = True else: account.is_active = False account.save() Questions: How do I retrieve ALL checkboxes, checked or un-checked? How can the retrieved list contains the status of each account, so that I can set the account's is_active field accordingly? -

cannot integrate third party markdown extension into django-wiki markdown
I'm trying to use this extension: https://github.com/aleray/mdx_semanticdata with django-wiki's markdown but I am unable to get it to work (though it works in the python/django shell just fine).

r.article_set.all() does not make a query through .objects whereas returns a query
In Django's tutorial,Django at a glance | Django documentation | Django r.article_set.all() does not make a query through .objects whereas returns a query. It's quick example: #mysite/news/models.py from django.db import models class Reporter(models.Model): full_name = models.CharField(max_length=70) def __str__(self): # __unicode__ on Python 2 return self.full_name class Article(models.Model): pub_date = models.DateField() headline = models.CharField(max_length=200) content = models.TextField() reporter = models.ForeignKey(Reporter, on_delete=models.CASCADE) def __str__(self): # __unicode__ on Python 2 return self.headline Working in Django shell, # Create a new Reporter. >>> r = Reporter(full_name='John Smith') # And vice versa: Reporter objects get API access to Article objects. >>> r.article_set.all() <QuerySet [<Article: Django is cool>]> Return a QuerySet,even if a Managers is not called. I search through the documentation and learn that A Manager is the interface through which database query operations are provided to Django models. At least one Manager exists for every model in a Django application. So I can understand: >>> Article.objects.all() <QuerySet [<Article: Django is cool>]> Django adds a Manager with the name objects to every Django model class.

How to write dynamic webpage in django
I am new in djnago and want to design dynamic website with the help of django framework. In my website website I have written a code in html where I defined a text box for an IP address and summary details to fetch the details from server and display on webpage, Here user first enter the IP address then click on submit button after that this will call you script which is present on django framework and script will execute command on server and display it's output then again execute another command and display it's output, so i'm looking a similar way of execution on django. Here except displaying commands output on server prompt it should publish output on webpage but one after another execution of commands on server. Please see below HTML code snippet. <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Netconf</title> </head> <body> <h3>Netconf Blast Command Generation:</h3> <table> <tr width=100%> IP Address <h4> <form method="POST">{% csrf_token %} Enter IP Address: <input type="text" name="cmd_string" id="cmd_string"/> </form> </h4> </tr> <tr> <br> <input type="submit" value="Submit"/> </tr> </table> <br> <table> <tr> <details> <summary>Cli show:</summary> <p>{{output}}</p> </details> </tr> <br> <tr> <details> <summary>Netconf show:</summary> <p>{{netconfoutput}}</p> </details> </tr> <br> <tr> <details> <summary>List of Netconf command:</summary> <p>{{netconfcommand}}</p> … -

Django Authentication - Created CustomUser and now I can't login anymore
I've put together a custom user model to store a few new fields and to keep the DB/UI models separate. I can create the user fine from a python shell and validate the password: >python manage.py shell -c " from itemdb.models import MyUser; user = MyUser.objects.create_user('mypass','AD','Joe','Smith','1233','joe@smith.com'); print user.check_password('mypass'); " True But when I point my app to the new "MyUser" model, I can't login via the web form anymore: Please enter a correct userid and password. Note that both fields may be case-sensitive. I created a new "users" table with the required fields and the hashed password values are being stored in the "password" field. I've written a few functions that may override the default functions, like "get", "save" etc. I'm guessing the issue is in there somewhere. My other guess, is somehow the form is not passing the right credentials. I know the easiest and cleanest way is to extend the model -- I've read all the posts & tutorials. But I want to keep the DB & UI code separate as much as possible. I think I'm close. What's missing? Any ideas as to why the validation isn't working via the website? Thanks.

JSON data from Django view
I want to query the database for one row of a table, and send this data in JSON format from a Django view: I checked Django serializer for one object, and I came up with: class BaseView(TemplateView): def get_context_data(self, **kwargs): context = super(BaseView, self).get_context_data(**kwargs) data = Language.objects.get(id=1) array_result = serializers.serialize('json', [data], ensure_ascii=False) context['oneLanguageItemInJSON'] = array_result[1:-1] return context But it sends the object like: "{ "fields": {"prop1": "val1", "prop2": "value2", "prop3": "val3" }, "model": "front.language", "pk": 1 }" Anyone knows what can be done here to get a normal JSON object? -

Django_q : not running without sync=True and assigning proper names
I am pretty sure I am missing something but I been thruthe documentation but couldn't find it. How do I give a task a proper name of my own instead of the one it generates on its own? I tried name='xxxxx' but name is not recognized but group works well. when I run async(), I can see message INFO Enqueed somenumber but the task never runs. But if I do sync=True (which the documentation even states and i noticed is for testing purposes), it does run and works pretty well. In my admin, i don't see new additions to scheduled tasks (not sure if thats where it should go either). -
parameterize testing with django settings
Am working on a django reusable package that am planning to use with multiple project. I've used pytest to build test suite, I've used parametrized helped in pytest to run a single test with multiple configuration. Yet, I would like to run all my tests using different settings combinations available_backends = [ 'django_profile.auth_backends.drf.RestFramework', 'django_profile.auth_backends.kong.Kong', ] def pytest_generate_tests(metafunc): # if 'stringinput' in metafunc.fixturenames: if 'auth_backend' in metafunc.fixturenames: metafunc.parametrize( 'auth_backend', available_backends ) @pytest.fixture(params=['auth_backend', ]) def auth_backend(request, settings): settings.DJANGO_PROFILE_AUTH_BACKEND = request.auth_backend return settings I experimented with the above approach, but this also means I have to add auth_backend to each test case, I don't believe this is ideal. Any one can recommend a way for me to run all my tests using different setting combinations? Regards -
Django - Best approach for managing 2+ types of users
There will be 2+ different types of users in my project, each with their own custom fields and permissions. Since I'm not changing the method of authentication, I plan to use the default User and create profile models. My question is, is it better to create a singular profile model, containing all the custom fields for each user type, and display the appropriate ones for each user (see method 1 below)? Or is it better to create a separate profile model for each user type (see method 2)? Method 1 from django.contrib.auth.models import User class Profile(models.Model): user = models.OneToOneField(User, ...) usertype1_customfield1 = models.CharField(...) usertype1_customfield2 = models.CharField(...) ... usertype2_customfield1 = models.CharField(...) usertype2_customfield2 = models.CharField(...) ... # and so on for each user type... Method 2 from django.contrib.auth.models import User class ProfileUserOne(models.Model): user = models.OneToOneField(User, ...) customfield1 = models.CharField(...) customfield2 = models.CharField(...) ... class ProfileUserTwo(models.Model): user = models.OneToOneField(User, ...) customfield1 = models.CharField(...) customfield2 = models.CharField(...) ... # and so on for each user type... -
Rebuild_index does not update new items Haystack Elasticsearch Django
Have been looking around for this solution but can't find anything. I have just started using Haystack == 2.6.1 and am using Elasticsearch==2.4.1 and Elasticsearch server 2.4.6. I was able to perform searches and get results after following haystack's getting started. After I run python manage.py rebuild_index It worked the first time because like I said I was able to perform searches. But then I added 3 entries to my db and tried to rebuild and/or update the index. But now I see this: RuntimeWarning: DateTimeField Order.dateEntered received a naive datetime (2017-11-11 16:07:54.324473) while time zone support is active. RuntimeWarning) Indexing 32 orders GET /haystack/_mapping [status:404 request:0.004s] And so when I search I still do not see my new entries. I now have 35 orders (it indexed only 32) and I'm seeing this 404 response for GET /haystack/_mapping. Sorry I am new so some of the questions may seem silly: What is haystack expecting to GET; I have a local server running for elasticsearch but is there supposed to be a haystack server as well? Would haystack fail to index new items due to the naive datetime WARNING? And do I have to restart the elasticsearch server each time I … -

Here's my gunicorn's setup: #!/bin/bash NAME="davidbien" DJANGODIR=/home/ec2-user/davidbien SOCKFILE=/home/ec2-user/davidbien/davidbien.sock USER=ec2-user GROUP=ec2-user NUM_WORKERS=3 DJANGO_SETTINGS_MODULE=davidbien.settings DJANGO_WSGI_MODULE=davidbien.wsgi echo "Starting $NAME as `whoami`" # Activate the virtual environment cd $DJANGODIR source ../virtual/bin/activate export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE export PYTHONPATH=$DJANGODIR:$PYTHONPATH # Create the run directory if it doesn't exist RUNDIR=$(dirname $SOCKFILE) test -d $RUNDIR || mkdir -p $RUNDIR # Start your Django Unicorn # Programs meant to be run under supervisor should not daemonize themselves exec gunicorn ${DJANGO_WSGI_MODULE}:application \ --name $NAME \ --workers $NUM_WORKERS \ --user=$USER --group=$GROUP \ --bind=unix:$SOCKFILE \ --log-level=debug \ --log-file=- Here's my nginx setup: upstream app_server_djangoapp { server unix:/home/ec2-user/davidbien/davidbien.sock fail_timeout=0; } server { listen 80; server_name ; access_log /var/log/nginx/guni-access.log; error_log /var/log/nginx/guni-error.log info; keepalive_timeout 52.56.193.57; # path for static files root /home/ec2-user/davidbien/davidbien/static; location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; if (!-f $request_filename) { proxy_pass http://app_server_djangoapp; break; } } } When running nginx I keep getting the following error in the logs: [crit] 23465#0: *1 connect() to unix:/home/ec2-user/davidbien/davidbien.sock failed (13: Permission denied) while connecting to upstream, client: 2.96.149.96, server: 52.56.193.57, request: "GET /faviconn.ico HTTP/1.1", upstream: "http://unix:/home/ec2-user/davidbien/davidbieen.sock:/favicon.ico", host: "52.56.193.57", referrer: "http://52.56.193.57/" What is wrong with this?
