Passing kwargs into get_or_create method in Django
I have a model with a custom save function, where I want to perform certain functions based on a condition like this: class ClassName(models.Model): def save(self, *args, **kwargs): reindex = **kwargs.pop("reindex") super().save(*args, **kwargs) if reindex: People.objects.create() Now inside a task I want to call the following: kwargs = { "reindex": False} ClassName.objects.get_or_create(**kwargs) When it does a create, it obviously runs the save function, but it's giving me an error saying reindex is not a field. I have been researching it for a while now and can't figure out what to do. Maybe someone can point me in the right direction. I just want to pass in an argument into the get_or_create, so that I can conditionally perform a certain function in the save method. Thank You in advance! -
Django: How to validate a birthdate entry as over 18
Probably a silly question, but what would be the easiest way of validating a date field form entry as being over 18 years ago in Django? (For a birthdate entry, validating age) -
Django "Lock wait timeout exceeded; try restarting transaction" while saving/updating a model
I'm still a little new to Django, and I'm getting (1205, 'Lock wait timeout exceeded; try restarting transaction') when I try to update my model via the admin interface. Earlier today, it was working, and I've been rolling back changes to the last working version to try to narrow down what seems to be the issue. The problem seems to be it failing to update and timing out. Just editing and hitting save in via the admin interface is triggering this issue. I've disabled any signal handling (post/presave) I had setup, but I think just the UPDATE call after hitting save changes is triggering this issue. I've looked into it and can kill the process after following this link: Getting "Lock wait timeout exceeded; try restarting transaction" even though I'm not using a transaction But it doesn't solve the problem. I can kill the process while it's going, but it's the only running query, and not even a big one at that. The model only has 7 fields, describing VPN servers I'm cataloguing. A show processlist gives me this: updating | UPDATE openvpn_client SET name = 'rsa_test1', local_ip = '2.2.2.2', vpn_ip = NULL, type = The end gets cut off … -

Django-Filter: Dynamically Create Queryset on Search or Hide Queryset until Search
I am using django-filter to search a model. Here is the code: filters.py: class PersonFilter(django_filters.FilterSet): lastName = django_filters.CharFilter(lookup_expr='icontains') firstName = django_filters.CharFilter(lookup_expr='icontains') class Meta: model = Person fields = ['lastName', 'firstName'] views.py: def search(request): people = Person.objects.all() people = PersonFilter(request.GET, queryset=people) context = {'filter': people} return render(request, 'myapp/template.html', context) template.html: <form method="get"> {{ filter.form.as_p }} <button type="submit">Search</button> </form> <table> {% for field in filter.qs %} <tr> <td> {{ field.idno }} </td> <td> {{ field.lastName }} </td> <td> {{ field.firstName }} </td> <td> {{ field.status }} </td> </tr> {% endfor %} </table> {% endblock %} </body> </html> Right now, this results in a table that mirrors my model with search boxes for first name and last name. The search works perfectly. How do I prevent the table of data from showing up initially? Logically, this could be done superficially (hide) or, better yet, substantially (dynamically create queryset). Is this possible? -
How to paginate django-filter results from form with Django?
Programming noob here. I have been using the django-filter app to filter models. When I try to use Django's paginator, to paginate from the filtered query, it does not work. All results are put on to one page, although the page numbers are on the bottom. When I click on a different page number, the results are unfiltered at put on to one page. Does any body know a solution to this? views.py from .models import Video from django.shortcuts import render from .filters import VideoFilter from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger def search(request): video_list = Video.objects.all() video_filter = VideoFilter(request.POST, queryset=video_list) paginator = Paginator(video_filter.qs, 1) page = request.GET.get('page') try: videos = paginator.page(page) except PageNotAnInteger: videos = paginator.page(1) except EmptyPage: videos = paginator.page(paginator.num_pages) return render(request, 'search/user_list.html', {'filter': video_filter,'videos':videos}) search/user_list.html {% extends 'base.html' %} {% block content %} <form method="post">{% csrf_token %} {{ filter.form.as_p }} <button type="submit">Search</button> </form> <ul> {% for video in filter.qs %} <li>{{ video.title }}</li> {% endfor %} </ul> {% if videos.has_other_pages %} <ul class="pagination"> {% if videos.has_previous %} <li><a href="?page={{ videos.previous_page_number }}">&laquo;</a></li> {% else %} <li class="disabled"><span>&laquo;</span></li> {% endif %} {% for i in videos.paginator.page_range %} {% if videos.number == i %} <li class="active"><span>{{ i }} <span class="sr-only">(current)</span></span></li> {% … -
Run Python Debugger "Standalone" Against Specific Django Module?
Is it possible to run the Python debugger against a specific module in a Django application without running the Django webserver and then executing pdb from within a view or model? I have a MailManager class inside a models.py file that contains some methods for sending emails. I'd like to debug one of these methods without having to run the Django server and then GET/POST the view that would call that method. I tried doing 'pdb myapp/models.py" and it seems to execute the very first command in my model file (which happens to be 'import logging'), but if I do 'dir(MailManager)', pdb tells me it's not defined. Is it possible to debug methods in this model class "standalone" in the way I'm describing? -
git pull bringing extra level in django project
I have a django project in which the project is called projectname, and the inner base directory is also called projectname. This is the norm for django projects. When I run git pull to the server after making changes in my development instance, git inserts the whole top level into that inner projectname directory. Here is a picture before running git pull: projectname - -app1 -app2 -app3 -static -templates -projectname -settings.py -urls.py -wsgi.py -views.py After I run git pull to bring in changes (git pull https://github.com/user/remoterepo), I have this: projectname - -app1 -app2 -app3 -static -templates -projectname -settings.py -urls.py -wsgi.py -views.py projectname - -app1 -app2 -app3 -static -templates -projectname -settings.py -urls.py -wsgi.py -views.py You can see, it has pulled the whole project into the subdirectory. I am running pull in the top directory, not in the subdirectory. In the repository, it looks like the first example, as the project should look, and as it looks in the repository and on my development machine. Why does the git pull process do an extra iteration and bring the whole project into the subdirectory? I have not seen this particular problem in my searches for a solution, so I wonder what I am … -
Detect new entries in django model through ajax
Is there a way I can check for new entries through ajax and update the page appending them to a div? I'm thinking about a situation like this: Client x access the page Client y post a new entry. Client z access the page. For client x, it will display a message: New entry found and a button that can get that entry. For client z, everything it's normal, as for client x before client y submitted a new entry. I haven't figured out how can I do this, actually, I have no idea, so I apologize because I haven't tried anything yet to show you. Thanks in advance for answers! -
Using DJango Models across Apps
Good afternoon, I have seen similar questions but none of the answers really resonate with me. I am new to django development and am trying to get use to the models. My question is how do I utilize a model from one app in another appropriately? For instance, I have a project, Project 1 that consists of the a Person app that manages the users profile. This app has the model for a person, but then that person is used in Activities for the activities they have completed, and another progress in a game. All of these apps need the person to be the key. I am not understanding how to make these relate. Thanks for your help as I become django-ified. -
Django bypasses permissions decorator for user registration and asks for authentication
I'm struggling with registering users for my API service. I've checked the methods and everything is valid, but I still receive an error code when POST'ing user registration data Error Code: {"details": "Authentication credentials not provided"} Settings.py I've added Basic Authentication, IsAuthenticated and TokenAuthentication to the framework REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.TokenAuthentication', 'rest_framework.authentication.BasicAuthentication', ) } The only thing that works currently is obtaining a token for an existing user: Urls.py url(r'^auth/', views.obtain_auth_token, name='get_auth_token'), Other endpoints in Url.py url(r'^login/', Login.as_view(), name='login'), url(r'^register/', Register.as_view(), name='signup'), I believe I'm not using the best practice for user registration or prepares I'm confusing the login with the signup.

Django Closed Socket Error with Repeated AJAX Calls [WinError 10053] An established connection was aborted by the software in your host machine
I'm trying to implement a live search through the jquery plugin Select2 in my Django 1.11.4 project. Running Python 3.6. When I type in the textbox, the server doesn't seem to be able to handle the number of requests and it closes, followed by these series of errors. I've spent a couple hours following a couple threads on SO SO(more) , Google, etc but none have a working solution.

Django models: Dependent fields
Say I have the following model: class Book(models.Model): due_back = models.DateField(null=True, blank=True) AVAILABILITY = ( ('a', 'Available'), ('o', 'On loan'), ('n', 'Not available'), ('r', 'Reserved'), ) status = models.CharField(choices=AVAILABILITY, blank=True) My problem here is that the two fields due_back and status depend on each other. For example if the book is "on loan" it does not make sense to have a due_back date. The goal is that the book may only have a due_back date if the book is "on loan". But how to do this, are there "best practices" for this kind of problems? -

How to put two different model's uuid and id in a same url?
I have two different model linked by a ForeignKey one contains a certain uuid and the other has a certain id. I'd like to be able to put these in the same URL. Here's the models.py : class Creation(models.Model): ... uuid = models.UUIDField(default=uuid.uuid4, unique=True) class User(models.Model): ... creation = models.ForeignKey(Creation, null=True) Here's what the URL pattern should look like : url(r'^edit/(?P<id>\d+)/(?P<uuid>[^/]+)/$', views.edit, name='edit'), Views.py def edit(request, id, uuid): user_uuid = User.objects.filter(id=id) user = get_object_or_404(User, id=id, uuid=user_uuid.creation.uuid) As you can see the view function doesn't make any sense since I don't see how what I'm trying to do should work but the User should be the id in the URL and the Creation should be the uuid since each user can have many Creations.
