"uid":"Invalid user id or user doesn't exist."
I am sending user registration credentials via postman in my Django project as below, and this returns me 201 response code. After that I am getting this link for activation as below Now I am getting uid and token from the URL as { "uid":"NjI5NWZmYmJkZTYzNTg1MDBjM2ZjYTIy", "token":"618-673ef2e1058d5f98fe41" } You can see my POST request to activate my account as below, as you can see in above image, after sending a post request with uid and token, it says { "uid": [ "Invalid user id or user doesn't exist." ] } And also I saw many uids on google, they are only of max length of 3 letters and my uid is greater than 10 letters. Is my uid is correct ? Thanks for your time! -
Django: Seed user to database with hash of password
Is there a nice way to use django-seed to seed a database with users which have their passwords hashed. I mean following. If I run this code in Django u = User(email="fero@example.com", username="fero") u.set_password('pass') u.save() it actually adds user fero to my database with his password in hashed form, i.e., in the database I see pbkdf2_sha256$320000$3rH6NIPNFDJX928EvkV9ni$ko5dwp7d4L8qg92FwnUc3DXu61AVmBYrzy0SlQDPojY= However, if I try to populate my database using django-seed using this code from django_seed import Seed seeder = Seed.seeder() seeder.add_entity(User, 15, { 'password': 'pass' }) inserted_pks = seeder.execute() then I put to the database 15 rows, each having a value of column password equal to pass, thus, the password is not hashed. Is there any nice way to tell django-seed to hash the password before putting it to the database? Many thanks for your help! -

Django email sending limit with GMAIL
I have successfully automated sending emails when a user registers my website and orders from my website. The problem is Gmail can only send 500 emails per 24 hours. That is so little when its a marketplace website. Is there a way to include two email accounts in settings.py file, so that when one email account finishes sending 500 emails the second one can start sending those emails? OR If there are other ways around this, I am thankful to all suggestions. -

How to group by json field data in django-mongodb
Hi, Thanks in advance... I am using Django 3.0.5, Python 3.8.0, and MongoDB 5.0 My requirement: Group the data by matching the value of Width, Height, Thickness, and Type fields. While grouping the data, do the summation of Length.

External URL into a iframe to embed an external url within Django
I would like to embed a pptx that is uploaded into a folder in OneDrive within a iframe tag in a Django template. I have the urls stored in a model and saved into the SQLite database. In this sense, in the views.py file, I have the following code: context = { 'selectedunit': selectedunit, 'url_to_be_inserted': MyModel.objects.filter(unit=selectedunit) } return render(request, 'web.html', context) The code for web.html is very easy: {% extends 'base.html' %} {% load static %} {% block content %} <div class="container col-lg-8"> <div class="center"> <iframe class="center" src={{ url_to_be_inserted.url }} width="100%" height="300%" frameborder="0"/> </div> </div> {% endblock %} The result is the snapshot below: While, I would like to embed the ppt into the web site. If I directly insert the URL, instead of using the context variable, it works. That is to say: <iframe class="center" src="https://..." width="100%" height="300%" frameborder="0"/> In this case, the result is as follows (ppt embedded into the Web site): The reason why doing in this sense is because, depending on the selectedunit variable, I would like to address a different pptx with a different URL and I would like to dynamically change the pointer (as you see above by filtering the model). How could I … -
Is there a better way to dynamically change the content of a div in django othen than AJAX?

Django-filters query params conflict
I am trying to work with filtering db by query params from the link that looks like this: {{url}}/api/books?author="XXX"&from=2003&to=2051&acquired=true I already handled author and acquired params but am stuck with from and to. My filter.py looks like this: class BookFilter(django_filters.FilterSet): author = django_filters.CharFilter(field_name="authors__fullname", lookup_expr="icontains") from = django_filters.NumberFilter(field_name="published_year", lookup_expr="gte") to = django_filters.NumberFilter(field_name="published_year", lookup_expr="lte") acquired = django_filters.BooleanFilter(field_name="acquired") class Meta: model = Book fields = [ "author", "from", "to", "acquired" ] I am looking for a way to assign these query params without overwriting key words (from and to) which is obviously a terrible idea. -

Reading from excel in python when cells have multiple operations
I am currently doing a project where all computations are done in excel i have multiple references and if conditions, the output of all of this is a number. The input is computed in python, it carries the information to the excel which has all the formulas to compute the output. I am trying to use the openpyxl library to get this value into my python programm, the written input works well but the last computed number that needs to be extracted as the result or output of the excel is not being done correctly. The output gives the operation not the result of the operation. I have tries using the data_only=True but does not work and the xlwings library solution dies not work either. I just need a command that once I introduce the input, executes all excel operations so that I can extract the result onto my python programm. ¿how can i do this? -
Django overriding get_context_data() not rendering in template
I'm relatively new to Django and I'm learning to work with CBV's and I am currently working on a simple todo list, I want to get specific user data for specific users.

Could I use memcached as a channel layer in Django?
I would like to use Django Channels in my application and I need a channel layer but I don't want to use Redis because, it is not available in my hosting plan. I have to get a dedicated or VPS server and I'm not ready for this yet. Instead, Memcached is available. I have searched the documentation of channels and Django and the internet I found nothing about it. But I know that before Redis, Memcached was used to implement the same. Basically I would like to configure my settings.py like that CHANNEL_LAYERS = { "default": { "BACKEND": "channels_mencached.core.MemcachedChannelLayer", "CONFIG": { "host": "amqp://guest:guest@127.0.0.1:5672/", }, }, } This is really a pseudocode, in reality I have no idea about how to configure Django for Memcached. I know Memcached is not officially supported but, is there a way to hack it and make it work on Django? If not, is there any alternative to be used in production, aside from Redis and RabbigMQ? -
