Problem downloading full database in Django
First I used export_import to download the database but I only downloaded a single table at a time but I need to export the entire database to a file then import it back. Now I'm trying to fix it with another way I just saw using resources If you could help me to change it to a view instead of a function I would be grateful.

How to remove "Select all" options from Django model admin
Django model admin allows to select all the objects in a page to take certain actions ('Delete selected' being one of them). After selecting all the model objects in a User model page, it gives an option to "Select all xxxx users" (xxxx being a number) as shown in the image. This allows the admin to select all the users and when exported to CSV, such a huge data size causes Gateway Timeout issue. We only want the admin to select the objects in a single page and not all of it in one go. Any help regarding this is appreciated. -
How to structure files in Django Rest Framework?
My requirement is the following: Create endpoints that will return various reports(json) representing organized data based on some specifications. Example: We have a car company with a lot of customers data. What I need to do is to generate reports which will contian month to month revenue from different categories of customers. Our project uses Django Rest Framework and the file structure is as the one below: mysite/ ├── manage.py │ ├── mysite/ │ ├── __init__.py │ ├── asgi.py │ ├── settings.py │ ├── urls.py │ └── wsgi.py │ └── app1/ ├── api/v1/ │ └── serializer/ │ │ └── serializer_model1.py │ │ └── serializer_model2.py │ └── view/ │ │ └── view_model1.py │ │ └── view_model2.py │ └── permissions.py ├── migrations/ │ └── __init__.py ├── __init__.py ├── admin.py ├── apps.py ├── forms.py ├── signals.py ├── models.py ├── tests.py └── views.py // not used So, for "car" model we have one view and one serializer file inside api/v1/. My questions are: Is this structure ok? Where I should write those queries to generate data for the reports? (new app?, different view?) If I have snippets of code which are used on multiple views, where should I place that code so I can … -
Django Notification HQ - I installed the app manually but no signal is being sent
I have a django app and I wanted to install django-notification-hq (https://github.com/django-notifications/django-notifications) I wanted to modify some parts of the app so I downloaded the repo and install it. I first install it using the recommended approach in github (here below) and it all worked. $ git clone https://github.com/django-notifications/django-notifications $ cd django-notifications $ python setup.py sdist $ pip install dist/django-notifications-hq* However, I wanted to try a different way (also because I wanted to learn) and add the app like if had developed it entirely. So I removed everything I did I took the notifications folder inside django-notifications and added it directly to my project. I changed my project settings and add 'notifications.apps.Config', I updated my req.tx and installed necessary libraries Now, the project runs and nothing breaks....however, no notification is being generated. I followed as much as possible the code and noticed that it's the notify.send() that doesn't send anything. This makes me think that there is something about signals that I am not doing right? -
Django templates - sudden appearance of "" in my html
Has anyone discovered the sudden appearance of "&#xFEFF;" in their html? -
I want to be able to render a Django object on the HTML and have other Django objects manipulate the rendered HTML
I am building fan website for my portfolio for a popular MOBA game. What I want to happen is when you go to a champions detail page that shows the champions stats (attack damage, magic damage, etc), I want the user to be able to click on an item, and that items stats will add on the already rendered stat value. For example, Champion "x" has 25 base attack damage. Item "a" has 5 attack damage. Click on item "a" and the champion's stats will now show 30 attack damage. When double clicking the item it will remove the added 5 attack damage and now show 25 attack damage again. The clicking method and order is not mandatory but preferred because that was my initial draft and since I am learning I think I should force myself to deal with it. I was wondering if someone could point me in the right direction for using event listeners/what javascript or method would be the best way to do this, other than loading every single item into global variables in the script file. Code for reference. I have heard about AJAX but I don't want to dive into that into the moment … -

Serialize JSON with a python keyword using the django-rest-framework
I have a django app (using the django-rest-framework) that needs to serialize and deserialize JSON payloads with the python keyword "import" as one of the fields. To prevent conflicts in the model, I can call the field import_flag and use the source option in the ModelSerializer. models.py class MyModel(model.Model): import_flag = models.BooleanField(verbose_name='Import') But (for obvious reasons) I cannot use the import keyword as to create a JSON field named "import" like so. serializers.py class MyModelSerializer(serializer.ModelSerializer): import = serializers.BooleanField(source='import_flag') def Meta: model = MyModel This field is present in the JSON I consume from a third-party's RESTful API and I also need to serialize it and send it back to the same third-party. Is there something like a destination option for the Django-rest-framework ModelSerializer class? I have been unable to find anything in the documentation. -
