Django Blog Archive-- Display List of Years and Months that Include Post
I'm trying to do something that I thought would be relatively simple, considering Django was built for news sites. Just want to get an archive list grouped by year/month count on the sidebar of my blog. Something like 2018 -Mar(3) -Feb (2) -Jan (6) I've done a lot of searching on here, but seems like it's been a while since anyone was looking to do something like this and everything else is outdated. I have been able to figure out how to create a monthly archive url/view/tempate and can display a month's posts by going to blog/2018/03 here is my blog's views class BlogListView(generic.ListView): model = Post context_object_name = 'post_list' queryset = Post.objects.all() template_name = 'post_list.html' class ArticleMonthArchiveView(MonthArchiveView): queryset = Post.objects.all() date_field = "posted" allow_future = True def blog_post(request, slug): blog_post = Post.objects.get(slug=slug) context = {'blog_post': blog_post} return render(request, 'blog/blog_post.html', context) and my urls (please ignore mix of url and path for now--working on that!) urlpatterns = [ url(r'^$', BlogListView.as_view(), name='blog'), url(r'^(?P<slug>[\w-]+)/$', blog_post, name='blog_post'), path('<int:year>/<int:month>/', ArticleMonthArchiveView.as_view(month_format='%m'), name="post_archive_month"), ] I think i will need to create another context field on all of my views in order to do this? But i don't really know where to start. I know that I … -
best practices in REST api design - Django/Angular
This is best practices/approach problem or in other words - what is optimal and expected approach. There are 4 models all linked in one-to-many (details below) I'm currently on DRF/Django and Angular interaction level. I need to identify all Authors where page.type=color and iterate foreach author in authors: console.log (author.author) foreach page in pages: console.log (page.content) Given it is fully linked relation, there are multiple options. Considered option was: a) nested router - cons: it requires upfront knowledge of IDs. b) filtering - cons: I couldn't find a way how to do it yet. Currently I don't have a direct pointer from page, back to Author, but theoretically it is one of the options possible however some (small) data overlap would be the case here then. For larger production deployment, which option is preferred (if any). Nested query requires two more SQL queries which might be more "expensive" than adding column to Page, pointing directly back to author. Or maybe approach should be the opposite, start from Author and go down through filtering to page level? At the end of the day, I need list of unique authors (where their book-edition-page fulfills type=) and then iterate through page elements fulfilling … -
Python string to list of dictionaries, access one dictionary to insert into django model
i'm new to python, using django.. i've searched many posts but am still having trouble getting a desired result: 1.- i have the following string received from an ajax post in a django view(its 2 rows of a angular ui-grid): data=[{"part_name":"33029191913","id":"5","qty":"3","ticket":"","comments":""},{"part_name":"3302919777","id":"3","qty":"323","ticket":"","comments":"test"}] 2.- then i am doing json.loads(data), which gives me the following: data ={'part_name': '3302919191', 'id': '5', 'qty': '33', 'ticket': '', 'comments': '33'}{'part_name': '3302919191', 'id': '5', 'qty': '33', 'ticket': '', 'comments': '33'} 3.- i want to create a dictionary that looks like the following in order to insert it into my model, via MyModel(**data): {'part_name': '3302919191', 'id': '5', 'qty': '33', 'ticket': '', 'comments': '33'} 4.- if i try to access one element of the data, example : data[0]['part_name'], it correctly shows '3302919191', but if i do data[0] or data[1], it gives me only the apparent keys: part_nameidqtyticketcomments, how can i separate the string received by ajax into dictionaries? thanks -

how to change temporary folder on django / gunicorn / nginx
I'm currently using django + gunicorn + nginx for my local service. I want to share big files (70Go maximum). thanks to lvm, I have now a 50Go partition (standard) for ubuntu + nginx +django + gunicorn and 5,4To (2 disk with lvm) for my file storage. my first probleme is that I store tmp file in my 50Go disk. When i have a file which is biiger than 50Go it can't work (obviously). I searched how to change the tmp file for django/gunicorn/nginx but my solutions didn't work. my second issue is when I upload a 22Go file, the 50Go disk seems to store my file Twice (I begin at 5Go taken and finish at 50Go) so I'm wondering how to reduce this space. -
subprocess not working in docker container
I'm literally going crazy and pulling my hair out because I can't seem to solve this particular problem. So here's the problem: I have a two containers: Django and celery. The user uploads a word document and the celery worker converts that word document to pdf and uploads to a s3 bucket. I'm using libreoffice --headless to convert it. So a user sends the file to an API endpoints and saves the word document in a folder called original and celery calls convert_office_to_pdf.delay which needs to convert the file and put it into another folder converted. Everything is working as intended apart from the celery function. This is how the code looks: def convert_office_to_pdf(original_file): ws = websocket.WebSocket() ws.connect('ws://web:8000/ws/converter/public/') #how the command will look like print('libreoffice --headless --convert-to pdf original/{} --outdir ./converted'.format(original_file)) subprocess.call('libreoffice --headless --convert-to pdf original/{} --outdir ./converted'.format(original_file), shell=True) ws.send(json.dumps({ 'message': '{}.pdf'.format(pure_file_name), 'progress': 75})) upload_file_to_s3(pure_file_name, 'pdf', ws) However, the function get's executed and nothing happens.

Django REST Framework - How to quickly checks user permissions?
I usually use the permission_required the decorator to quickly deny users from accessing the view. from django.contrib.auth.decorators import permission_required @permission_required('my_app.view_mymodel',login_url='/sign_in/') def my_view(request): ... Now, I'm using DRF and I'm trying to find a proper way to checks user permissions. Right now, I'm using the DjangoModelPermissions which is fine, but since it works according to the defined view's queryset, sometimes I need to checks permissions that are not the ones defined for the view's queryset. Is there a way to quickly check permissions just by providing a list of perms' strings? Note: I know that I can extend BasePermission and define my own logic, but would produce a lot of classes. -

Migrating from webpack to angular-cli
we are using angular and django BFF as single project. We are trying to migrate from webpack to angular-cli In webpack we are using webpack-bundle-tracker plugin which generates webpack-stats.json file in dist directory on doing "npm run build" webpack.config.js plugins: [ new BundleTracker({path: __dirname, filename: './assets/webpack-stats.json'}) ] Output in webpack-stats.json looks like below: { "status":"done", "chunks":{ "app":[{ "name":"app-0828904584990b611fb8.js", "publicPath":"http://localhost:3000/assets/bundles/app-0828904584990b611fb8.js", "path":"/home/user/project-root/assets/bundles/app-0828904584990b611fb8.js" }] } } Above file is read by Django to do hot reload.

django ajax post empty data
I'm trying to post data to a django view using ajax. I have no errors just there is no data returned.

However I can see in the log in the terminal : [22/Mar/2018 22:15:26] "GET /?QQww=1 HTTP/1.1" 200 9746 so essentially the data are parsed in the url? Thanks in advance. -
Site users logged out after Django 1.8 > 1.11 upgrade
We recently upgraded one of our projects from Django 1.8 to 1.11 (one point release at a time). This seems to have logged out all of our site end users. It's not the end of the world, but it was somewhat disruptive, and probably something that we would have attempted to code around if we had taken the time to discover that it would happen. Is there any documentation on why this happens (a backwards-incompatible migration for the Session object... a change to the way the session cookie is checked... maybe something like that?) and which upgrade(s) may cause users to be logged out? Also, for future 1.8 > 1.9 > 1.10 > 1.11 upgrades (as well as future upgrades) is there any sort of interim authentication middleware that can be implemented to authenticate existing sessions into the new system?) -

Django: getting the link of a generatet token to send it with an email?
So I created a registration Email to confirm that the User is really using the email he used for registration. This is the registration view: def registration(request): if request.method == 'POST': form = StudentForm(request.POST) if form.is_valid(): fname = request.POST.get('Vorname', 'None') lname = request.POST.get('Nachname', '') email = request.POST.get('Email', '') pwd = request.POST.get('Passwort', '') pwd2 = request.POST.get('Passwort_wiederholen', '') if not pwd: raise ValueError('User must have a pwd') if pwd == pwd2: new_user = User( fname = fname, lname = lname, email = BaseUserManager.normalize_email(email), user_type = 'S', is_active = False ) new_user.set_password(pwd) new_user.save() #email code token = default_token_generator.make_token(new_user) uid = urlsafe_base64_encode(force_bytes(new_user.pk)) send_mail( 'Welcome!', f'Link: {#what should I put in here? }', settings.EMAIL_HOST_USER, [str(new_user.email)], fail_silently=False) return HttpResponse('Pls activate your account using the link we send you too your email') else: form = StudentForm() return render(request, 'account/registration.html', {'form' : form}) This is the url I have in my urls.py for the token: url(r'^users/validate/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z] {1,13}-[0-9A-Za-z]{1,20})/$', views.activation_view, name='user-activation-link') Since I don't now how to get this link, I'm not even sure if it's even properly working or if it's even getting generated.

How to change output-file extension of django-dbbackup module?
I am trying to use django-dbbackup module to backup my database. After running dbbackup it saves a db dump with a name something like this: default-user-2018-03-22-220805.psql Then I delete 1 last row in one tables of my db. Next I run dbrestore and get the follow: > Finding latest backup Restoring backup for database 'default' and > server 'None' > Restoring: default-user-2018-03-22-220805.psql > Restore tempfile created: 407.0 KiB > Are you sure you want to continue? > [Y/n] y > Following files were affected But after that - nothing happens. The deleted row is not restored in my db. I have read some where (unfortunately already lost that page) that to restore my db the dump file must be in .tar format. Also I have tried to use that .psql with pgAdmin 4 - to restore db via UI tool. But got an error that input file is not a valid archive. And last I tried to use that file with Windows cmd running pd_restore and got: pg_restore: [archiver] input file does not appear to be a valid archive So the question is: how to use django-dbbackup dbrestore with its generated file or how to change the extension format of … -

What is the securest way to get image from users in Django
I already can get image from user and save it successfully but I'm wondering something after see so many warning about getting image from users in Django documents. Django says that we can't exactly trust the image file which come from users. Because it can be another file (like an HTML file) but with another header/meta data (like JPG/PNG). So, our system can't understand that isn't a real image file. There are security risks if you are accepting uploaded content from untrusted users! See the security guide’s topic on User-uploaded content for mitigation details. said on Django docs. Here is more: Django’s media upload handling poses some vulnerabilities when that media is served in ways that do not follow security best practices. Specifically, an HTML file can be uploaded as an image if that file contains a valid PNG header followed by malicious HTML. This file will pass verification of the library that Django uses for ImageField image processing (Pillow). When this file is subsequently displayed to a user, it may be displayed as HTML depending on the type and configuration of your web server. So, what is the safest way to handle images coming from users? I want to … -

My JS loop which generates widgets: for(var index=0;index<json.length;index++) { {% load static %} gridster.add_widget('<li class="new" ><button class="delete-widget-button" style="float: right;">-</button><img src="{% get_static_prefix %}images/'+json[index].html+'"></li>',json[index].size_x,json[index].size_y,json[index].col,json[index].row); }; My JSON var json = [{ "html": 'abc.png', "col": 1, "row": 1, "size_y": 2, "size_x": 2 }, { "html": "xyz.png", "col": 4, "row": 1, "size_y": 2, "size_x": 2 }, { "html": "def.png", "col": 6, "row": 1, "size_y": 2, "size_x": 2 }, { "html": "abc.png", "col": 1, "row": 3, "size_y": 1, "size_x": 1 }, { "html": "def.png", "col": 4, "row": 3, "size_y": 1, "size_x": 1 }, { "html": "abc.png ", "col": 6, "row": 3, "size_y": 1, "size_x": 1 } ]; My HTML: <div class="gridster"> <ul> </ul> </div> The Fiddle is what I am trying to do In fiddle I have added a button to delete the image but it doesnt seem to work and after image … -
Getting value from drop-down in Django
been struggling to work out how to get a value from my drop-down. I'm pretty sure the problem is in text = form.cleaned_data['fields'] but I'm unsure how the method works.
