Node as opposed to Django for running big python scripts
I am building an app that requires running a python script that implies a significant wait time. I am having a hard time deciding whether I should stick with Django or should dive into Nodejs, due to the fact that I find plugging in my front end (React) a pain point, and because I would like to work with Apollo Server. What is your opinion? Is Nodejs not suited for running such python scripts? Thank you! -
See django template in pytest failure output

How to display data from a model method
Good evening community I am new to programming and I have been working on a Django project to enhance my skills. I would like to display data from a method model in my templates.

django-allauth: reset password email, send the key instead of a link?
With django-allauth, to change password, user go to /password/reset/ and input a email address and confirm (user is redirected to /password/reset/done/ afterwards). Then the user receive an email. User get a link (password/reset/key/(?P<uidb36>[0-9A-Za-z]+)-(?P<key>.+)/) with a key from the email, and through that link, user can change password. However, I'd like to reduce the pages user have to open. Here're what I want: instead the reset link, send to user the key only overwrite password_reset_done.html to add a key input form (method="GET") user enter the key and confirm, and get redirected to password/reset/?key=xxx 2 is easy to implement, but I don't know how to implement 1 and 3. Here is the password reset email django-allauth send by default. There's only a password_reset_url. How to replace it with the generated key? And how could I overwrite the url from password/reset/key/(?P<uidb36>[0-9A-Za-z]+)-(?P<key>.+)/ to password/reset/?key=(?P<uidb36>[0-9A-Za-z]+)-(?P<key>.+)? -
django-background-task - A specific kind of task are not running whereas other tasks still run
I have been using django-background-task for a while but the last background-task function I just added is not working. I created a new backgroud_task as below in a marketplace/tasks.py from background_task import background @background(schedule=1) def background_pair_new_account(lv_external_id: str, lv_siren: str, lv_vat_number: str, lv_pack: str) -> None: print(lv_external_id, lv_siren, lv_vat_number, lv_pack) The background task is called as below: from marketplace.tasks import background_pair_new_account background_pair_new_account("12345678", "789234678", "FR01789234678", "full") The background task is well created in backend: TASK NAME TASK PARAMS RUN AT marketplace.tasks.background_pair_new_account [["12345678", "789234678", "FR01789234678", "full"],{}] 28 juillet 2021 09:59 But when I run python manage.py process_tasks, my task doesn't run.

Dictionary web app in Django - how to switch languages so that word in search bar don't delete
I am working on Dictionary web application - similar to Google translate. I have this problem: there are only have two languages, eng and cro and search bar in which user types word that requires translation. When user starts typing, for example some english word, and sees that dictionary is set to CRO-ENG, user needs to switch dictionary to ENG-CRO. But then, word which user started to type when dictionary was set to CRO-ENG deletes. I know it is because ENG-CRO and CRO-ENG are two separately pages but I need that text which is typed in search bar stays there despite switching between languages. There is a part of code (search bar) from eng-cro.html page: {{form.errors}} <form method="GET" action="" autocomplete="off" {% if srch %} value="{{ srch }}" {% endif %}> <div class="search"> <input type="text" name="srch" placeholder="search" id="search" autocomplete="off" list="ddlautocomplete_eng" /> <datalist id="ddlautocomplete_eng"> {% for result in dicty%} <option>{{result.engWord}}</option> {% endfor%} </datalist> </div> </form> There is a part of views.py (after searching, user gets a list of words which starts with the word he search): def eng_to_cro(request): words = Dictionary.objects.order_by('engWord') srch = request.GET.get('srch') if srch: words = words.filter(engWord__istartswith=srch) else: words = None args = {'words': words, 'srch': srch} return render(request, 'app/eng-cro.html', … -

Pip cannot install anything on ubuntu server

Retrieve Similar Objects by Tags in Django
In the book Django 3 by Example (Chapter 2), the author suggests the following to retrieve posts similar to 'current post' based on tags (via the taggit module). post_tags_ids = post.tags.values_list('id', flat=True) similar_posts = Post.published.filter(tags__in=post_tags_ids).exclude(id=post.id) similar_posts = similar_posts.annotate(same_tags=Count('tags')).order_by('-same_tags','-publish')[:4] I understand the flow: Get a list of all the IDs for the tags in the current post. Filter all posts basis the list derived above, and exclude the current post. Add a calculated field to the posts derived above that specify the number of tags they have in 'common' with current post. For example, if current post has tags 'one' and 'two', and another post has 'two' and 'three', the calculated field should be same_tags = 1 (i.e. 'two') Here's where I am confused: In point 2 above, will I get a QuerySet that has duplicate posts. For example, if a post has 2 tags in common with the current post, will the resulting QuerySet have 2 instances of the post? I tried this in shell, and this is what it seems to return. For example, if post has two tags in common with current post, it will be included twice. But I am not sure why this should be the … -

`python manage.py runserver` shows an old webapp page I developed
I am learning Django so I've created many Django webapps under one directory. For example, \webapps \polls \polls \api \manage.py ... \ponynote \ponynote \frontend \manage.py ... I didn't use a virtualenv for developing django apps. I don't know whether it's the reason that causes the problem as below. App 1 python manage.py runserver works all fine. (default port 8000) App 2 python manage.py runserver still shows the App 1 page. Method I tried: change the port python manage.py runserver 8001, it shows App 2 page. try to find the process ID PID, and kill it. No sign of port 8000. However, this isn't the best solution since I can't change the port everytime when developing a new django app. Does anyone have a clue why this happens? Kudos. -

Django Rest Framework (DRF) sets JSON field to Empty in the to_internal_value function
