I want to install Django in a virtual environment managed by pyenv from Ansible
I would like to build development environment with Vagrant and Ansible. The composition is Pyenv + Python 3.6 + Django When you execute AnsibleScript below - name: install django pip: name: django version: "{{ django_version }}" virtualenv: "{{ work_dir }}" virtualenv_command: pyenv become: false An error occurs. fatal: [127.0.0.1]: FAILED! => {"changed": false, "failed": true, "msg": "Failed to find required executable pyenv in paths: /usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/vagrant/bin"} Is there a solution? -
Does someone know how to implement Jquery Datatables in a Django framework?
I am trying to create a datatable using Datatables and Django, however I am lost. The most I get my web page to display is the json data. Below are my models: from __future__ import unicode_literals from django.db import models class LikeDefectMatrix(models.Model): area = models.TextField(db_column='AREA', blank=True, null=False, primary_key=True) # Field name made lowercase. type = models.TextField(db_column='TYPE', blank=True, null=True) # Field name made lowercase. defect_name = models.TextField(db_column='DEFECT_NAME', blank=True, null=True) # Field name made lowercase. update = models.TextField(db_column='UPDATE', blank=True, null=True) # Field name made lowercase. code = models.BigIntegerField(db_column='CODE', blank=True, null=True) # Field name made lowercase. class Meta: managed = False db_table = 'Like_Defect_Matrix' Here are my views: from .models import LikeDefectMatrix from django.http import HttpResponse from django.core import serializers # Create your views here. def postsjson(request): object_list = LikeDefectMatrix.objects.all() json = serializers.serialize('json', object_list) return HttpResponse(json, content_type='application/json') this is my base.html file: {% load staticfiles %} <!DOCTYPE html> <html lang = "en"> <head> Example <link rel="stylesheet" type="text/css" href="{% static 'css/bootstrap.min.css' %}"> <link rel="stylesheet" type="text/css" href="{% static 'css/jquery.dataTables.min.css'%}" /> <script src="{% static 'js/jquery.js' %}"></script> <script src="{% static 'js/bootstrap.min.js' %}"></script> <script src="{% static 'js/jquery.dataTables.min.js' %}"></script> </head> <body> <div id="page-wrapper"> <div class="container-fluid"> {% block body %} {% endblock body %} </div> </div> </body> {% block js … -
/ and /blog are not not showing any of the content from Posts. I believe the issue has something to do with get_absolute_url() and reverse
While /blog doesn't show any of the posts, / is showing empty bootstrap modules for every post - so it knows how many posts there are and therefore something is coming through. I believe the issue started when I attempted to add another module to base.html The directory structure is as follows: - src [Folder] - content [Folder] - migrations [Folder] - __init__.py - admin.py - apps.py - models.py - tests.py - views.py - main [Folder] - settings [Folder] - __init__.py - base.py - migrations [Folder] - __init__.py - db.sqlite3 - models.py - urls.py - views.py - wsgi.py - posts [Folder] - migrations [Folder] - templatetags [Folder] - __init__.py - admin.py - apps.py - forms.py - models.py - tests.py - urls.py - utils.py - views.py - templates - base.html - blogbase.htm models.py - posts is as follows: from __future__ import unicode_literals from django.conf import settings from django.contrib.contenttypes.models import ContentType from django.core.urlresolvers import reverse from django.db import models from django.db.models.signals import pre_save from django.utils import timezone from django.utils.safestring import mark_safe from django.utils.text import slugify from markdown_deux import markdown from comments.models import Comment from .utils import get_read_time # Create your models here. # MVC MODEL VIEW CONTROLLER #Post.objects.all() #Post.objects.create(user=user, title="Some time") class … -

Urls and file organization in a Django project
I am developing a website with django, and I don't know how I should structure my project. Let's say that my project tree is: main ├───_main | ├── __init__.py | ├── settings.py | ├── urls.py | └── wsgi.py ├───_accounts | ├── models.py | ├── forms.py | ├── urls.py | ├── views.py | └── ... └───_website ├──_static | └──_website | ├── css (...) | └── js (...) ├──_templates | └──_website | └── (html files...) ├── urls.py ├── views.py └── ... I have two apps ('accounts' and 'website') in my project 'main'. The 'accounts' app implements the user model and the authentication process. The 'website' app controls non-model related stuff, like home page and so on. Of course, there will be more apps... At this moment, all the web files (html, css, js...) are stores in 'website' (static / templates folders), and website/urls.py handles all urls. # website/urls.py from django.conf.urls import url, include from .views import index from accounts.views import LoginView, LogoutView, RegisterView urlpatterns = [ url(r'^$', index, name="index"), # Accounts url(r'^login/', LoginView.as_view(), name="login"), url(r'^logout/', LogoutView.as_view(), name="logout"), url(r'^register/', RegisterView.as_view(), name="register"), ] It makes sense to me that user-related web files like login form, register form, etc., should be store in static and … -

How can i have two separate log formats for django and celery?

Filter selectbox in Django Admin to Children that don't have Parents

When I want to create a "Customer", part of that process is to select the port that the customer will be attached to. This appears as a selectbox. Everything works great, except that I'd like to only see ports that haven't already been assigned to a "Customer". This is a one to one relationship, so perhaps I … -

Difference between Django validate and a validator
From the Django docs The validate() method on a Field handles field-specific validation that is not suitable for a validator. This implies that validate() is different than a validator. What is the difference? I'm curious because I'm using a custom validate on a custom form field. It raises a ValidationError, but the code keeps running and calls Django's validate and clean afterwords and doesn't do anything with the ValidationError that I raised. -

Django - Checkboxes & ManytoMany relationships in TemplateView
I have a app where users can register their company and then select a number of settings from a list. Both the company and services are different models. class Company(models.Model): name = models.CharField(max_length=100) (...) class Service(models.Model): name = models.CharField(max_length=100) linked_companies = ManyToManyField(Company, blank=True) What I want is to have a large list of services, with checkboxes behind their names, so the owner can quickly select the services that he wants to connect to his model. This used to be done through the admin interface, but due popular demand this feature is moved to 'the front'. The problem is that I do not know how to fit this into the traditional (generic) view/form combinations that we' ve been using so far, since two different models are involved. I am trying a more custom solution, but have hit a wall and I am wondering if you could help me.

Nginx, gunicorn, django, ubuntu - not displaying images
fellow humans I just set up a server on digitalocean and deployed my app. Everything else works fine including my javascript and css. but for some reasons beyond me, uploaded images by a user aren't displaying I think i got a lead but still dont know where to go. would really appreciate it if you could point me to the right direction so here is my image model(upload_to) class Image(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='images_created') title = models.CharField(max_length=2000) slug = models.SlugField(max_length=200, blank=True) url = models.URLField() image = models.ImageField(upload_to='images/%Y/%m/%d') description = models.TextField(blank=True, null=True) created = models.DateField(auto_now_add=True, db_index=True) users_like = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name='images_liked', blank=True) and here is my nginx conf server { listen 80; server_name 67.207.87.22; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { alias /home/kingiyk/stylplus/static/; } location /media/ { alias /home/kingiyk/stylplus/media/; } location / { include proxy_params; proxy_pass http://unix:/home/kingiyk/stylplus/stylplus.sock; } } When i upload an image, it gets saved to /home/kingiyk/stylplus/images/2017/07/26 stylplus/images is the image app I think the '2017/07/26' part is as a result of my upload_to being 'images/%Y/%m/%d (year/month/day).

Not seeing performance increase running django test /w postgresql on ramdrive
For a django project, the tests are running slower and slower as the models grow and the number of migrations as well. A single unittest i have timed now at 200s. I followed this post: http://tech.marksblogg.com/test-django-on-ram-drive.html to work on a ramdrive only for the testing but strangly enough i'm not seeing any improvement.... So i expect something is not going as it should... I have debugged some and did see the TABLESPACE statements being generated towards postgres, for instance: ... CREATE TABLE ""django_content_type"" (""id"" serial NOT NULL PRIMARY KEY USING INDEX TABLESPACE ""ram_disk"", ""name"" varchar(100) NOT NULL, ""app_label"" varchar(100) NOT NULL, ""model"" varchar(100) NOT NULL) TABLESPACE ""ram_disk""",,,,,,,,," Could it be that postgresql rejects it? And how can i test/see if the ram drive is actually being used? Paul -

django rest framework - browsable api remove delete

Here is my permission: class CanRetrievePasswordFolder(permissions.DjangoObjectPermissions): def has_permission(self, request, view): if request.user is None: return False else: return True def has_object_permission(self, request, view, obj): access_levels = ['Owner', 'Admin', 'Read'] if get_permission_level(request, obj) is None: return False else: level = AccessLevel.objects.get(pk=get_permission_level(request, obj).level_id).name if request.method in permissions.SAFE_METHODS: return True else: for access in access_levels: if level == access: return True else: return False
