I am attempting to use .latest() to retrieve the most recent object but I am getting field error and an extra "-"
The code seems pretty innocuous: home_post = Post.objects.latest('-timestamp') but it returns the following error: FieldError at / Invalid order_by arguments: ['--timestamp'] There seems to be an extra "-" that isn't in my code. Where is this coming from? Is sublime adding this? Is this what is actually causing the error? -
Django ImportError: cannot import name
I have an application notes and model name defined as notes/models.py from shorturls.models import ShortUrl class Note(models.Model): # columns here def __str___(self): return self.title def post_save_note_receiver(sender, instance, created, *args, **kwargs): if instance and created: ShortUrl.objects.create(note=instance) and another app shorturls to store short URL for each record with model shorturls/models.py from notes.models import Note class ShortUrl(models.Model): note = models.OneToOneField(Note, on_delete=models.CASCADE, blank=True) short_key = models.CharField() def __str__(self): return self.short_key @receiver(pre_save, sender=ShortUrl) def pre_save_short_url_receiver(sender, instance, *args, **kwargs): instance.short_key = unique_short_key_generator(instance) @receiver(post_save, sender=Note) But on python manage.py makemigrations, It gives error as File "path_to_app/shorturls/models.py", line 7, in <module> from notes.models import Note ImportError: cannot import name 'Note' -
Angular - lazy loading from custom folder
I have Angular 4 application with several lazy loaded modules. I working as expected as standalone (in local development server), however when I try to deploy it using Django application... Main page - index.html is generated by Django view from the built index.html by angular-cli, all pathing to bundle.js files are adjusted to use static content pathing and all is working until I try to lazy load... It tries to find file 0.*****.js in a root directory, where the file is not, because is in static content location... Changing <base href="/static/"> would load lazy file(s) but would also change the whole url and corrupt routing... (I am also looking to static content be on external server) How I can adjust path there files to be lazy load (0.*****.js) are located without changing <base href="/static/"> ? -
Copy data from Django Form to Django Model so it can be saved to the database
I am using the Wizard Form Tools to gather information from users by using a sequence of screens. I followed the information below. http://django-formtools.readthedocs.io/en/latest/wizard.html https://github.com/django/django formtools/blob/master/docs/wizard.rst In my case, I am using 4 forms controlled by the Wizard. One of the forms looks like the following: forms.py class OwnerStep1( forms.Form ): contactsalutationid = forms.ModelChoiceField(queryset=Mstrgensalutationtype.objects.all(), label="Salutation") contactfirstname =forms.CharField(label="First Name") contactlastname =forms.CharField(label="Last Name") contactofficephoneno =forms.CharField( label="Office Phone No.") contactcellphoneno =forms.CharField( label="Cell Phone No") I saw in the documentation, that one could use the following to get the data out of the form: views.py class OwnerCollectDataView( SessionWizardView ): template_name = 'authorization/collect_owner_data_form.html' def done(self, form_list, **kwargs): for form in form_list: hold = self.get_form_step_data(form) [... snip ...] The results I have are in the attachment What I am seeking now is to copy this information (in the variable "hold") into Model so that that it can be stored in the database. The model I have looks like the following: models.py class Mstrstorehead(models.Model): [... snip ...] companyname = models.CharField(max_length=30, blank=True, null=True, verbose_name="Company Name") businesstypeid = models.ForeignKey(Mstrgenbusinesstype, models.DO_NOTHING, db_column='businesstypeid', blank=True, null=True, verbose_name="Business Type") ourmission = models.CharField(max_length=200, blank=True, null=True, verbose_name="Our Mission") contactsalutationid = models.ForeignKey(Mstrgensalutationtype, models.DO_NOTHING, db_column='contactsalutationid', blank=True, null=True, verbose_name="Salutation") contactfirstname = models.CharField(max_length=20, blank=True, null=True, verbose_name="First Name") contactlastname = … -
Flush particular session in Django
How can I clear particular session variable ? Official docs talk about using .flush() as in request.session.flush() but I noticed it doesn't only clear that particular session, it clears also my session in admin as superuser. I really don't like the idea of me and my mates working in admin or whatnot while users logging in and out and logging us out at the same time. There must be better way. I tried del the session variable but somehow it still remembers it after refresh. What is the right way to do it ? -
Add username to URL with AuthenticationForm FormView
I'm coming from Laravel and new to Django. I'm trying to add a username to the url after login. This has been asked before a few times, but I have yet to make the solutions work (they involve having a model attached to the generic FormView class). Here is what I have: urls.py path('login/', views.Login.as_view(), name='login'), # Logged in user path('home/<str:username>', views.UserIndex.as_view(), name='user_index'), views.py class Login(views.AnonymousRequiredMixin, views.FormValidMessageMixin, generic.FormView): authenticated_redirect_url = '/' form_class = LoginForm form_valid_message = "You have successfully logged in" template_name = 'pythonmodels/registration/login.html' success_url = reverse_lazy('pythonmodels:user_index', args=("Bill",)) def form_valid(self, form): username = form.cleaned_data['username'] password = form.cleaned_data['password'] user = authenticate(username=username, password=password) if user is not None and user.is_active: login(self.request, user) return super(Login, self).form_valid(form) else: return self.form_invalid(form) forms.py class LoginForm(AuthenticationForm): def __init__(self, *args, **kwargs): super(LoginForm, self).__init__(*args, **kwargs) self.helper = FormHelper() self.helper.layout = Layout( 'username', 'password', ButtonHolder( Submit('login', 'Login', css_class='btn-primary') ) ) In the views.py file, I would like the args for success_url to be the username of the user that was just authenticated. Should this be done in the LoginForm class? I have also seen that you can go to an intermediate url and then get the User data, but this seems like a terrible extra step. I would like to … -

Tell Django to use test database created by Pytest
I am currently running pytest with my Django project. When I first start executing my tests, a test database correctly gets created. I have verified this.

django - linking the register form info to user profile model
I am trying to make a webapp that includes register/login operations. The login is working fine but the registration form is frustrating. I have a class registration form that inherits from UserCreationForm. The users are created and seen in the admin page when created but the problem I am having is not being able to see them in my UserProfile model in the admin page. It does not link the information and I could not find a way the link them. Here is the registration form: from django import forms from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm class RegistrationForm(UserCreationForm): email = forms.EmailField(required=True) city = forms.CharField(required=False) country = forms.CharField(required=True) first_name = forms.CharField(required=True) last_name = forms.CharField(required=True) username = forms.CharField(required=True) class Meta: model = User fields = ( 'username', 'first_name', 'last_name', 'country', 'city', 'email' ) def save(self, commit=True): user = super(RegistrationForm, self).save(commit=False) #user.first_name = self.cleaned_data['first_name'] if commit: user.save() return user Here are my models: class UserModel(models.Model): user = models.OneToOneField( User, on_delete=models.CASCADE ) username = models.TextField(max_length=30, default="") first_name = models.TextField(max_length=30, default="") last_name = models.TextField(max_length=30, default="") country = models.TextField(max_length=30, default="Which country are you from?") city = models.TextField(max_length=30, default="Which city are you from?") class ColorChoice(models.Model): user = models.ForeignKey( 'UserModel', on_delete=models.CASCADE ) color1 = models.IntegerField() color2 … -
Make active class only visible when the button is clicked
I have 2 buttons that pop a modal and they are highlighted whenever they are clicked, but the first button is already highlighted by default even tho the modal is closed when the page loads. My goal is to remove the class="active" for the default state, add it when the buttons are clicked and remove it when the modal is closed. What's the easier way of doing it? Here's my HTMl: <div class="assistance-body"> <nav style="width: 20%; float: right;"> <ul class="nav nav-tabs nav-justified"> {% for key, data in resources %} <li{% if loop.first %} class="active"{% endif %}> <a data-toggle="tab" href="#{{ key }}" segment-event="Modules: Tutor: Clicked {{ key|capitalize }} Section" segment-not-track-if-class="active" onclick="openAssistance()" > <i class="icon-{{ key }} icon-sm"></i> <span class="sr-only">{{ ('resources.tabs.' ~ key ~ '.title') | trans }}</span> </a> </li> {% endfor %} </ul> </nav> <div class="assistance" id="assistance" style="display: none;"> <button type="button" class="close" toggle-class="oc-open" onclick="closeAssistance()" aria-hidden="true">&times;</button> <div class="tab-content" style="display: block; z-index: 10; "> {% for key, data in resources %} <div class="tab-pane{% if loop.first %} active{% endif %}" id="{{ key }}"> {% include data.view with { 'category': data.category, 'resources': data.resources } %} </div> {% endfor %} </div> </div> </div> -
Printing to PDF a Django Template using Google Chrome Remote interface
I have a Django Server (Django==1.11.7) This Django server runs on a VM ( myvm ) and I access it's content from the host machine ( Not really relevant, just to give some content what myvm means ) This Django server serves a template. Inside this template, I reference some static files. For example: <link rel="stylesheet" href="http://myvm:8080/static/css/mycss.css"> <img src="http://myvm:8080/static/images/myimage.png"> If I curl or request these files from python for example, it works, both from my host machine and the vm. requests.get("http://myvm:8080/static/css/mycss.css").text That for example returns the expected content. In the browser, the HTML renders correctly. Accessing my Django server both from the host and the vm results in a perfectly good page. More over, copying the source code of the page and accessing the file also renders correctly. For example, if I literally copy paste the source from the browser into mysite.html and look at that, file:///some/local/path/mysite.html that also renders correctly. Looking in the Django logs, I see messages like this: [15/Dec/2017 00:00:00 - 1513349355] INFO [django.server:124] "GET /static/images/myimage.png HTTP/1.1" 200 68 The same for css or scripts. The static file mysite.html sees references to files on that server, requests them, and it receives them successfully. The exact same thing … -

How can I load a class based view by slug?

Why is this Django-Channels consumer running synchronously?
My understanding of websockets and django-channels is very superficial, so please bear with me. Before testing a more serious use case, I'm trying to gradually append a piece of data to my HTML, using jquery and django-channels. Here's my app/consumers.py: @channel_session_user def ws_receive(message): user_group = str(message.user.username) user_profile = message.user.user_profile.id message_text = json.loads(message['text']) room = "pk" for i in range(1, 5): time.sleep(1) Group(user_group).send({'text': json.dumps(room)}) I have the jquery code successfully connecting to the websocket, and calling this consumer upon a button click. First identify the click: $('#search_button').on('click', function(e) { e.preventDefault(); // prevent form submission var myval = $('#qos').val(); console.log(myval); mysocket.send(JSON.stringify(myval)); }); Which triggers onmessage: mysocket.onmessage = function message(event) { var data = JSON.parse(event.data); console.log(data); if (data === 'pk') { console.log("True"); $('#result_div').append('<p>' + data + '</p>') } }; The problem is, All of the pk pargraphs (4 in total) are being "spit out" in one bunch to my page. I thought this: for i in range(1, 5): time.sleep(1) Group(user_group).send({'text': json.dumps(room)}) Is supposed to send the message one-by-one to the websocket, which should then also inject the HTML one by one..that's happening is that it's waiting ~5 seconds (number of loops), and then adding 5 pk paragraphs at once. What am I misunderstanding? … -
same name in INSTALLED_APPS for 3rd party lib
I have a project with 4 marketplaces one of which is Jet. Also I've got 'jet-admin' skin that I should add to INSTALLED_APPS as 'jet'. My marketplace app is defined as 'vmode.apps.marketplaces.jet'. There's a conflict between them and it's close to impossible to rename everything connected to marketplaces.jet. I guess that renaming 3rd party lib 'jet' is an option. I made some research and found that there's a label in AppConfig, so I tried to make class JetAppConfig(AppConfig): name = 'jet' label = 'jet_skin' and added to: INSTALLED_APS = [ 'vmode.apps.marketplaces.base.apps.JetAppConfig', 'vmode.apps.marketplaces.jet', ] after I made migrations it returned: CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0001_initial, 0002_delete_userdashboardmodule in jet_skin). To fix them run 'python manage.py makemigrations --merge' and after I made it returned: raise ValueError("Could not find common ancestor of %s" % migration_names) ValueError: Could not find common ancestor of set([u'0001_initial', u'0002_delete_userdashboardmodule']) How can I change lib name without touching marketplace.jet.models\migrations? Any help appreciated. -
Django application memory usage
I am running Django application (built on Django Rest Framework) on Digital Ocean server with following characteristics: 4gb RAM 2 CPUs 60 GB drive I am using Gunicorn to run Django app and Celery to manage queue. Database is MySQL. As I can see CPU usage is really low, but memory usage seems to be large. After I deploy I noticed that python3 process uses even more memory (something around 75%). Whenever I deploy I am running after_deploy script, which contains following: service nginx restart service gunicorn restart chmod +x /mnt/myapplication/current/myapplication/setup/restart.sh source /mnt/env/bin/activate cd /mnt/myapplication/current/ pip3 install -r requirements.txt python3 manage.py migrate --noinput >> /mnt/migrations/migrations.log rm -f celerybeat.pid rm -f celeryd.pid celery -A myapplication beat -l info -f /var/log/celery/celery.log --detach celery -A myapplication worker -l info -f /var/log/celery/celery.log --detach Are these numbers expected? And if not, how can I investigate what is going wrong? -
