Django-cms admin url 404 after language change
I recently started learning Django & Django CMS, and was trying to change the language of my website from English to Dutch, I migrated over my pages using Page.objects.filter(languages='en-us').update(languages='en') Title.objects.filter(language='en-us').update(language='en') CMSPlugin.objects.filter(language='en-us').update(language='en') In my settings.py I also changed LANGUAGE_CODE to 'nl' and set my languages and CMS languages as follows LANGUAGES = ( ## Customize this ('nl', 'Nederlands'), ) CMS_LANGUAGES = { ## Customize this 1: [ { 'code': 'nl', 'name': 'Nederlands', 'redirect_on_fallback': True, 'public': True, 'hide_untranslated': False, }, ], 'default': { 'redirect_on_fallback': True, 'public': True, 'hide_untranslated': False, }, } This works like a charm for the normal pages, but as soon as I try to open the admin interface I get the following error Request Method: GET Request URL: http://localhost:8000/nl/en/admin/cms/page/?language=en Raised by: cms.views.details Using the URLconf defined in PinManagementSite.urls, Django tried these URL patterns, in this order: sitemap.xml nl/ admin/ nl/ ^cms_login/$ [name='cms_login'] nl/ ^cms_wizard/ nl/ ^(?P<slug>[0-9A-Za-z-_.//]+)/$ [name='pages-details-by-slug'] nl/ ^$ [name='pages-root'] ^media/(?P<path>.*)$ ^static/(?P<path>.*)$ The current path, /nl/en/admin/cms/page/, didn't match any of these. As far as I can see I configured it all correctly, but when I go to the admin pages it tries to route me through /nl/en instead of just /nl/ and I can't figure out why. For completeness … -
Access a field's custom class in Django's ModelForm
I'm working on a ModelForm in Django that uses a Model, which has a custom CharField. When handling form errors I want to show the user valid examples (I thought this shouldn't be part of the raised ValidationError). However, when I try to access the fields using myform.fields by getting the invalid fields and the corresponding error messages using myform.errors.items() type(myform.fields["myfield"]) returns <class 'django.forms.fields.CharField'> instead of my custom MyField. Therefore myform.fields["myfield"].test() raises AttributeError: 'CharField' object has no attribute 'test'. How do I get the correct MyField instance from form.fields? class MyField(models.CharField): pass class MyModel(models.Model): myfield = MyField(max_length=20) class MyForm(forms.ModelForm): class Meta: exclude = tuple() model = MyModel myform = MyForm() print(type(myform.fields["myfield"])) -

Adding CSS to Django template email

Request can only be served after Gunicorn Worker Timeout and new Worker is booted
I have a Django application in Docker using Gunicorn to run the web server. If I request any URL, say app.com/dashboard, the page loads for 30 seconds. The reason it loads for 30 seconds is because that's how long the Gunicorn web worker to timeout, exit, and boot a new worker with a new pid. This is what shows up in the logs after a request and waiting for the worker to timeout. web_1 | [2021-04-28 17:51:57 +0000] [1] [CRITICAL] WORKER TIMEOUT (pid:7) web_1 | [2021-04-28 12:51:57 -0500] [7] [INFO] Worker exiting (pid: 7) web_1 | [2021-04-28 17:51:57 +0000] [9] [INFO] Booting worker with pid: 9 Once the new worker is booted, the page is served instantly. Has anyone experienced something similar to this before? -
Result type from cursor.fetchall() is list of tuples, but doc shows tuple of tuples
from django.db import connection conn = connection.cursor() conn.execute("some select query..") print( conn.fetchall() ) This shows that result from cursor.fetchall() is list of tuples, though in docs there is example: >>> cursor.execute("SELECT id, parent_id FROM test LIMIT 2"); >>> cursor.fetchall() ((54360982, None), (54360880, None)) That shows that result is not list, but tuple of tuples. Little bit confused, What I'm missing here? Thanks -

DJango use templates from seperrate AWS S3 Bucket
I have a Django server running in an elastic beanstalk environment. I would like to have it render HTML templates pulled from a separate AWS S3 Bucket. I am using the Django-storages library, which lets me use static and media files from the bucket, but I can't figure out how to get it to render templates. The reasoning for doing it like this is that once my site is running, I would like to be able to add these HTML templates without having to redeploy the entire site. Thank you -
Apache httpd and Easy Apache 4 (Installing mod_wsgi for python app)
It's been a while but I am running into an issue and could not find any answers elsewhere. I pay for a dedicated server that is running Easy Apache 4 with Centos 7. I have root access to everything so no limitations. I am in the process of deploying a Python/Django app on the server for a client. When trying to install mod_wsgi it errors out stating it needs the package httpd-mmn. I can install the httpd module using yum but I am worried about conflicts since the server is using Easy Apache 4. Is this a relevant concern? I have a bunch of php sites on my server and I am afraid I'll break it. For the record, I do not want to use the experimental easy apache mod wsgi as it's, well...experimental and a use at your own risk situation. Any thoughts or recommendations would be great. -

Select only the options that are related to another model in Django
I'm building a student/school app in which a student can belong to only one school and can choose Course options for that School they're in. Currently, I'm doing it the wrong way by having the course field at Student relate do Course, which will of course provide the entire list of courses in my app. What I'd like my app to be able to do is select only from courses that that school have added as their courses. How to do that? class Course(models.Model): name = models.CharField(max_length=32) class School(models.Model): name = models.CharField(max_length=32) courses = models.ManyToManyField(Course) class Student(models.Model): name = models.CharField(max_length=32) school = models.ForeignKey(School, on_delete=models.CASCADE) course = models.ManyToManyField(Course) # change 'Course' for ??? -
How to display content from many-to-one relationship
So I'm going crazy trying to figure out what seems like it should be a dead-simple task. I'm making a portfolio site. It has 2 models, Project and Image. Project contains most of the data for each project, while Image is in a many-to-one relationship to supply Project with a variable number of images per Project. On the homepage, I would like to show each project in its own section, and the images for each project in their respective sections. Currently, I have the projects displayed, and I'm able to display all the images from the database under each section: {% for image in images.all %} <img src="{{ image.image.url }}" alt=""> {% endfor %} I cannot, for the life of me, figure out how to display just the images for each respective section in the template, despite diving through pages of documentation, stack answers, and web posts. I've seen so many examples of how to query a model in this type of relationship from the views/model layers, but none of these seem to work in the template layer. I also don't know how I would perform the query on a different layer and send that through to the template, if … -
Django session variable not working when using AJAX
I have to delete an item and, for that, the user clicks in some "Delete" button in the page and Javascript makes an AJAX request (including the CSRF token in the header of the request) for a Django view to proceed with the deletion. My Django view is processing the request properly and deleting the item. But, in the same view, I do the following: Delete the item Put a message on the request.session['message'] Redirects to the 'list page' The 'list page' view checks if there is some 'message' in request.session and returns it to the page to show in some alert to the user. However, this mechanism is not working for this case, when using AJAX. It is like both the 'delete' view session and the 'list page' session are not the same, because it does not find the 'message' in the request.session. Here are some of the files involved. urls.py: ... urlpatterns = [ path('agenda', views.agenda, name='agenda'), path('<int:reuniao_id>/excluirReuniao', views.excluirReuniao, name='excluirReuniao'), ] views.py: def agenda(request): reunioes = ReuniaoEmpresa.objects.all() if 'message' in request.session: message= request.session['message'] del request.session['message'] else: message= '' context = { 'reunioes' : reunioes, 'message' : message } return render(request, 'agenda/agenda.html', context) def excluirReuniao(request, reuniao_id): reuniao = get_object_or_404(ReuniaoEmpresa, … -
