Forbidden access for django apache2 media files
I have trouble with access my files from django admin site. I save files without any trouble, but when I try open it, I get error: Forbidden You don't have permission to access /media/file.pdf on this server. In django project settings: STATIC_URL = '/static/' STATIC_ROOT = '/full/path/to/static/' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') In project urls.py: if settings.DEBUG: urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) In my virtualhost I added this settings: Alias /static/ "/static/folder/" Alias /media/ "/meida/folder/" <Directory "/static/folder"> Require all granted </Directory> <Directory "/media/folder"> Require all granted </Directory> But still get this error. Where can be bug/mistake? -
Django define default view
I migrated my Django project to an Ubuntu distant server. I'm using mod_wsgi in order to runserver and I have some questions about default page. I'm really new in this domain and I apologize if my question is bad or useless .. When I want to connect to my Django application, I have to write something like that : http://172.XX.XX.XXX/Home/login/ If I write just : http://172.XX.XX.XXX I get : Page not found Using the URLconf defined in Etat_civil.urls, Django tried these URL patterns, in this order: ^admin/ ^BirthCertificate/ ^Identity/ ^Accueil/ ^Home/ ^captcha/ ^Mairie/ The current URL, , didn't match any of these. My question is : How I can define redirected url in order to write http://172.XX.XX.XXX in my browser and go directly to http://172.XX.XX.XXX/Home/login/ for example ? This is urls.py file from my project : from django.conf.urls import url, include from django.contrib import admin from django.conf.urls.static import static from django.conf import settings from BirthCertificate import views from Identity import views from Accueil import views from log import views from Mairie import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^BirthCertificate/', include('BirthCertificate.urls')), url(r'^Identity/', include('Identity.urls')), url(r'^Accueil/', include('Accueil.urls')), url(r'^Home/', include('log.urls')), url(r'^captcha/', include('captcha.urls')), url(r'^Mairie/', include('Mairie.urls')), ] Because I just want for example, write my IP … -
Django auto generate identifier number
I want to define the unique identifier field for the Django user model. I want the numbers like 0000-0000-0001, 0000-0000-0002 when save the models. Approach: I can define field as char and post_save signal can update the identifier based on primary key. Is there any automatic way to generate number like this for the user identifier (not primary key) -

creating/ guessing the underlying models from JSON response
I am building an application and it was easier for me to think of the JSON response I will get when hitting a specific URL and then based on that now I am trying to build my models. JSON looks like following: { "idea": { "title": "", "description": "", "tags": [ "", "", "" ], "priority": "", "PD": { "question1": "", "question2": "" }, "TOC": { "question1": "", "question2": "" }, "HOW": { "question1": "", "question2": "" }, "issues": [ "issue1", "issue2" ], "tasks": [ "task1", "task2" ], "note": "", "image": [ "base64(1)", "base64(2)" ] } } I started creating models like following (this is more or less Django syntax for models, but I guess logic remains the same for any framework): class Tag(): name = string; idea = ForeignKey(Idea); class Prototype(): base64 = string; idea = ForeignKey(Idea); class Issue(): name = string; idea = ForeignKey(Idea); task = ManyToMany(Task); class Task(): name = string; idea = ForeignKey(Idea); class Idea(): title = string; description = string; priority = string; note = string; I am not sure about the PD, TOC and HOW parts.

How to model a Many-to-many relation when the target model is a tuple in django?
I have a model with translated text fields. Now the issue is that often i don't have translations for 'some' languages and i do like to publish the models already. An easy (default) ay out is to fallback to the default language (as per django model translations) but actually i'm thinking of explicitly enabling the instance for a language. For this i like to have a many-to-many relation with the LANGUAGES tuple from settings. So basically it's like a CharField with choices set to LANGUAGES but then in a select many fashion. One idea is to add a Language model for this and create a standard ManyToMany relation; but it doesn't feel right since i have nothing to add except for the language code itself; so why add a model.... Another alternative is to apply a PickleField and serialize a [] of language-codes. But that obviously is a quick/dirty solution as there is no validation etc... Anyone an idea on this issue? Paul -

Scheduled, timestamped sqlite3 .backup?
Running a small db on pythonanywhere, and am trying to set up a scheduled .backup of my sqlite3 database. Is there any way in the command line to add a time/date stamp to the filename, so that it doesn't overwrite the previous days backup? Here's the code I'm using, if it matters: sqlite3 db.sqlite3 .backup dbbackup.sqlite3 .quit Running every 24 hours. The previous day's backup gets overwritten, though. I'd love to just be able to save it as dbbackup.timestamp.sqlite3 or something, so I could have multiple backups available. Thanks! -

Django: setting template_name doesn't work in Class-based View
I have a ProductListView: class ProductListView(ListView): model = Product template_name = 'products/product_list.html' context_object_name = 'products' I tried to create another ListView listing Product: class VoteView(ListView): model = Product template_name = 'recommendation/rec_product_list.html' context_object_name = 'products' But when I tried to access VoteView in a browser, it occurs errors : it rendered product_list.html, not rec_product_list.html. So I debugged it and fount out that get_template_names() returns, ['recommendation/rec_product_list.html', 'products/product_list.html']. I could fix this by inserting this code: def get_template_names(self): return ['recommendation/rec_product_list.html'] But wonder whether there is better way than this one.. Thanks -

Plugin with editable link element
While implementing a Django CMS site, I’m a little stuck on link management (internal or external). In my project I have a specific box plugin the operator is to use quite often. I added screenshots of edit dialog and box rendering at the end of the question. The edit dialog is nice, but right now the button is just a char field. So the link selection, either to a page within Django CMS or to an external URL, is missing. I looked for a link field, but until now I am lost. How to add the feature to let the operator select an internal or external link ? The plugin consists of these parts: models.py from django.db import models from cms.models.pluginmodel import CMSPlugin from djangocms_text_ckeditor.fields import HTMLField class CardPlugin(CMSPlugin): title = models.CharField(max_length=256,default='') description = HTMLField(configuration='CKEDITOR_SETTINGS', default='') button = models.CharField(max_length=256,default='') def __str__(self): return str(self.title) cms_plugins.py class CardCMSPlugin(CMSPluginBase): model = CardPlugin name = 'Card' render_template = "card-default.html" card-default.html {% load cms_tags %} <section class="card card--primary-light"> <div class="card__inner"> <div class="card__content"> <div class="card__text"> <h2 class="card__title"> {{ instance.title }} </h2> <p class="card__description"> {{ instance.description }} </p> </div> {% if instance.button %} <div class="card__buttons"> <a href="#0" class="button button--primary-inverse">{{ instance.button }}</a> </div> {% endif %} </div> </div> … -
Redirect from https to https doesn't work. Can't find server, ngnix

How to turn on PostgreSQL VERBOSITY in django db connection?
This is a follow up question to this: Postgres: More verbose error message: I am missing the table name PostgreSQL 9.6 improved error messages with version 9.6. With psql you can enable it \set VERBOSITY verbose. How to enable this for every connection inside django ORM? Background: I want better error messages. Example: I am missing the table name in messages like this IntegrityError: null value in column "date" violates not-null constraint DETAIL: Failing row contains (10005, null, f, TEST, MAIL). I think the relevant part of the 9.6 release notes is this: Add support in libpq for regenerating an error message with a different verbosity level (Alex Shulgin) This is done with the new function PQresultVerboseErrorMessage(). This supports psql's new \errverbose feature, and may be useful for other clients as well. -

How to formulate a function for Django Celery task
