django-safedelete 1.3.0 - Cannot migrate
I built an internal app that used django-safedelete. I was working fine for months, until i recently upgraded my distro, and tried to add a field to my model. I also upgraded my python modules, everything is up-to-date, and no errors during the upgrade. Now I cannot migrate anymore: if I "makemigrations" I get an error message "django.db.utils.OperationalError: (1054, "Unknown column 'gestion_ltqmappsetting.deleted_by_cascade' in 'field list'")" if I add a boolean "deleted_by_cascade" field in my ltqmappsetting table, then the "makemigration" works, but the "migrate" fails with "MySQLdb.OperationalError: (1060, "Duplicate column name 'deleted_by_cascade'")" I tried removing the field after makemigrations, but the migrate fails with the first error message. I also tried removing the "migration" operations in the 0087...migration.py file, but it does not have any impact. Is there anyway to update the migration file between the makemigrations and the migrate commands ? Thanks a lot for any help on this. jm -
Is this security concept suitable for ehealth records webapp?
I'd like to hear your opinion on my application design regarding data security. Context & Build Steps Personal electronic health records, main purpose of app is storage (read-only). The application will be used by staff. data exchange with third parties. Users will extend to external staff. Mobile App for visualisation of health records. Users will have access to their data (read-only) Stack Backend: python+django (webapplication) DB: postgresql // Divided in two groups personal data (like name, age, adress, ...) and health records (reports, lab values, ...). health records are only files, no database records in that sense (db will have path reference in on column). All of the health records are stored in the aws S3 bucket. Host: heroku + aws S3 bucket for file storage Thoughts & Considerations The app will come with a authentification and authorisation functionality. I consider the health records with higher priority regarding data security than personal data. So what I was thinking is to upgrade my heroku server with heroku shield services which would add security features server-side and make breaches from that side harder. Additionaly I would like to use the encryption service of aws bucket to encrypt all the files in the … -

How to display data from Rest API in a template
I made an API using Django Rest Framework and I've been able to use it to create come charts using ChartJS. In the same API, after the data used for the charts I have some other data that I want to be displayed simply as a number in the same Django template, but I'm really unsure on how to do that. My API: HTTP 200 OK Allow: GET, HEAD, OPTIONS Content-Type: application/json Vary: Accept { (...CHARTS.JS DATA...) "total_employees": 1, "total_vehicles": 3, } I have already imported the data into the template together with the data I used for the charts. Template: <script> {% block jquery %} var endpoint = '/api/chart/data/' (Chart.JS part) var totalemployees = [] var totalvehicles = []; $.ajax({ method: "GET", url: endpoint, success: function(data){ (Chart.JS data here...) totalemployees = data.totalemployees totalvehicles = data.totalvehicles (ChartJS stuff here...) }, error: function(error_data){ console.log("error") console.log(error_data) } }) (Other ChartJS stuff here...) {% endblock %} </script> I would like to do something like this in the template: <h3 class="text-center m-4">Total number of employees: ("total_employees" value (which in this case is 1)</h3> <h3 class="text-center m-4">Total number of vehicles: ("total_vehicles" value (which in this case is 3)</h3> -
Django Sessions Loose Data with url containing target="_blank"
In my django app, I store the current breadcrumb data (an array) in the session object. When I have a link that includes target="_blank", the session data is lost. I assume this is normal operation, but just want to check that this is true. Any suggestions on where to store the breadcrumb array if I need to retrieve it when I use target="_blank" in my urls as well as whenever a page loads? Keep in mind, the breadcrumb data is on a per user basis. Thanks! -
GitHub App - User Authentication/Authorization through GitHub APIs
I am new to GitHub Apps. I have used GitHub OAuth before, but finding it a bit difficult to understand the user authentication and authorization for GitHub Apps. My use case is as follows - A user will visit my website, login with their GitHub credentials and at that time the user needs to accept the permission I seek from their profile (ex. Repository, PRs, etc.) and display those repositories and PR on my website and perform some actions on them. I have primarily 1 question at a high level. The API endpoints and what all keys are needed to authenticate and authorize a user so as to get all the requested items like repositories etc. and more importantly the next time the user logs in he should not need to accept the permission to access his repositories. (Similar to this codefactor site) I would like to have an architecture level solution if not a code example. I am using Python (Django) to build my project but code examples in other languages are also welcomed. -

ajax response can be seen fine in the alert box but can't print it out get undefined instead
I am trying to print out the response to an ajax request. I am getting a "undefined" when (down there) I write ${obj[property][0]} it follows the index to 1, 2 etc I can see both in the console and by alert-ing the response (data) that it does send the correct data in the form of a dictionary although it surely is json because that is what I send as response (and that is what web tools shows). However if I alert-out the "obj" I get "object" but can't see real values This is the ajax call: $(document).ready(function(){ // open document ready $('.botontest').on('click',function(){ // opening click function var value = $(this).val() alert(value); $.ajax({ // opening ajax obviously url:"{% url 'bill' %}", type:'POST', data:{'name':value, csrfmiddlewaretoken: '{{csrf_token}}'},// closes data field datatype:'json' }).done(function(data) { obj = JSON.parse( data); alert(data); // it prints me all data alright in the "alert" box // I leave out the headers. for (const property in obj) { tableHTML += "<tr><td>" tableHTML += `${property}</td> <td>${obj[property][0]}</td><td>${obj[property][1]}</td>\ <td>${obj[property][2]}</td><td>${obj[property][3]}</td><td>${obj[property][4]}</td><td>${obj[property][5]}</td>\ <td>${obj[property][6]}</td><td>${obj[property][7]}` tableHTML += "</td></tr>" } tableHTML += "</tbody></table>" //place the tableHTML in the document $("#respuesta").html(tableHTML); }); // closing ajax group console.log(value); }); // closing the click function });// closing document ready </script> My response … -
Custom manager in Django MultiDB
I'am using MySQL and PostgreSQL in my Django project. Below are the settings: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'mysql_db', 'USER': 'username', 'PASSWORD': 'password', 'HOST': 'hostname', 'PORT': '3306', }, 'postgres_db': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'pgsql_db', 'USER': 'username', 'PASSWORD': 'password', 'HOST': 'hostname', 'PORT': '5432', } } And this is the sample model from postgres_copy import CopyManager class Items(models.Model): class params: db = "postgres_db" sales_value = models.CharField(max_length=255, null=True, blank=True) primary_email = models.CharField(max_length=255, null=True, blank=True) objects = CopyManager() I want to use Items.objects.all().to_csv('./path/to/csv) this ORM to export model data to CSV. I have used this before in exporting large dataset to csv. But in this configuration it gives below error psycopg2.errors.SyntaxError: syntax error at or near "." LINE 1: COPY (SELECT `sales_item`.`id`, `sales_item`.`sales_value`,... This seems to be an issue with multiDB. If I run this ORM in single DB configuration, or even if I set default alias on PostgreSQL this works fine. CopyManager seems to be getting default alias somehow which I have no idea about. How can I run this ORM in current settings without any issues? Any help would be appreciated. Thanks in advance. -
Building a dynamic asynchronous filesystem in django: best practices
I am trying to rebuild our website in Django, and I am currently facing a series of rather difficult challenges for which I am not prepared. I was hoping to get some help in the matter. The website I am building is an online archival platform for artists called Lekha. The core of Lekha is the dashboard page (which you can check out on this link, just sign in with the email stacko@test.com and the password test if you have the patience). On the dashboard page, users have access to a hierarchical filesystem that we would like to function like a desktop filesystem for ease of use. Users can use the filesystem to organize their 'artworks' into folders. These artworks themselves are a collection of media, along with the metadata of the artwork. To upload this media and fill in the metadata, users will use a form. If users want to edit an artwork's metadata, they can do so through an auto-populated form on the same page. The issue that I am facing is that I am struggling to find an elegant way to make all of this happen without reloading the page. Users need to be able to add, … -

FCM push notifications with AWS Lambda function
I have a Django project (Django 3.1.2) using fcm-django(version 0.3.7) to send push notifications. The application is deployed in AWS Elastic Beanstalk and the notifications are sent with no problems. I have the same code deployed in a AWS Lambda Function to run 3 cron jobs that check some conditions (each 15 minutes) and to send push notifications if necessary. But on the Lambda Function the notifications are not send. After some digging I understood that the function couldn't communicate with the outside because it was in a VPC. Which made absolute sense since I could see in the logs new HTTPS connections starting towards fcm.googleapis.com:443 and then "Task timed out after 30 seconds" To give internet access to an Amazon VPC-connected Lambda function, we would need to route its outbound traffic to a NAT gateway in a public subnet. So I followed the steps in How do I give internet access to a Lambda function that's connected to an Amazon VPC? to give internet access to the Lambda Function. I added a call to http://dog-api.kinduff.com/api/ to my code. That call now goes through so the NAT configuration worked! However, I continue to have a timeout to fcm.googleapis.com... What can … -

Can't scroll a dropdown menu in a Bootstrap navbar
I have a fairly simple home page that currently contains a navbar with two dropdown menus. One of menus contains a large number of entries but it doesn't allow me to scroll to the end of the list. I created a fixed-top navbar with a navbar-brand, a home link and two dropdown menus. One of the menus is short with just 2 items and the other contains about 32 items. Everything renders fine but when I open the larger of the two menus, it displays most of the items but will not allow me to scroll to the rest. I expected the navbar to stay fixed to the top of the page while I could scroll all the way to the bottom of the large menu. -

Does this Python ABC interface, implementations, factory pattern make sense?
I've got a Django app and a message queue and I want to be able to switch between queue services easily (SQS or RabbitMQ for example). So I set up a BaseQueue "interface": class BaseQueue(ABC): @abstractmethod def send_message(self, queue_name, message, message_attributes=None): pass And two concrete classes that inherit from BaseQueue: class SqsQueue(BaseQueue): def send_message(self, queue_name, message, message_attributes=None): # code to send message to SQS class RabbitMqQueue(BaseQueue): def send_message(self, queue_name, message, message_attributes=None): # code to send message to RabbitMQ Then in settings.py I've got a value pointing to the implementation the app should use: QUEUE_SERVICE_CLS = "queues.sqs_queue.SqsQueue" Because it's a Django app it's in settings.py, but this value could be coming from anywhere. It just says where the class is. Then I've got a QueueFactory whose job is to return the queue service to use: class QueueFactory: @staticmethod def default(): return import_string(settings.QUEUE_SERVICE_CLS)() The factory imports the class and instantiates it. I would then use it like so: QueueFactory.default().send_message(queue_name, message) It works, but I was wondering if there's a more Python way to do it? Like with some magic methods? -
