Equivalent Form field for Model field Bigintegerfield in Django
Django has an inbuilt Model field called BigIntegerField, but it does not have a corresponding Form field, and there is only an IntegerField available for use with forms. Is there any problem with this mismatch? I want to store phone numbers in these fields (10-digits), so the IntegerField Model class cannot store all positive 10-digit values as it is only up to 2147483647. -

Django Mock Test - Caching GraphQL Query
The code below is my attempt to cache the response of a graphql query and a test to make sure the content is getting cached.

JQuery Infinite scrolling with Waypoints slight error with event listener

Filtering objects through a range of object attribute in Django-rest-framework

Creating an updating search form

How to filter django tables2 results for unique values of a specific column

How to keep relative path in Django templates?
I have imported a front-end project including completed .css, .js, .html files into Django templates. They can work when run .html directly. But if run them in Django server, all links with relative path should be modified as Django style such as <link rel="stylesheet" type="text/css" href="{% static 'style.css' %}" /> instead of <link rel="stylesheet" type="text/css" href="css/style.css" />. Is there any method to keep the orginal relative path in .html file and also can run in Django? -
Backend and frontend on separate Heroku instances
I'm building a single page app with an Angular frontend and a Django Rest API on the backend. I intend to deploy the app with Heroku. My understanding is that there are two approaches that I can take: Use nginx as a reverse proxy, allowing communication between the server and the client. Deploy two separate Heroku instances, one for the API (e.g. myapp.com/api) and a second for the Angular App (e.g. myapp.com). The frontend would be hosted at myapp.com and make requests to myapp.com/api. Now for my question: Is one of these approaches better than the other? Is one approach more secure than the other? Note: I'm using Angular 4 with the angular cli. -
Django static_url when script_name set?
So I'm trying to run multiple instances of Django on a server for now, one under /dev, one under /test, etc.. The web server is setting the correct SCRIPT_NAME setting and I can serve pages, templates, the whole admin panel fine, except for static assets. Static assets are served by Django using WhiteNoise. The application is supposed to use the value of SCRIPT_NAME as the static URL, ie all static assets are served from the application root. So far I've tried the following settings against the admin panel: # SCRIPT_NAME = '/dev' Set in env # URL for static assets should be `/` STATIC_URL = '/' # Browser looks for static assets in `/`, drops script_name STATIC_URL = None # Browser looks for static assets in `/`, drops script_name STATIC_URL = `/dev/` # Browser looks for static assets in '/dev/dev/` I'm wondering if I'm missing a setting here or if the problem might be elsewhere. Going by the docs I understand that STATIC_URL = '/' should work? -
Django REST framework - multiple lookup fields?

Adding Collapsible fields in django-grappelli

In the case of ModelAdmin the following example is given: class ModelOptions(admin.ModelAdmin): fieldsets = ( ('', { 'fields': ('title', 'subtitle', 'slug', 'pub_date', 'status',), }), ('Flags', { 'classes': ('grp-collapse grp-closed',), 'fields' : ('flag_front', 'flag_sticky', 'flag_allow_comments', 'flag_comments_closed',), }), ('Tags', { 'classes': ('grp-collapse grp-open',), 'fields' : ('tags',), }), ) From reading the documentation it is not clear where in a Django project the code block above would live. Does it go into [project_name]/[app_name]/admin.py? -
How can I tag/refer user with @ like in facebook or twitter?
There is something for tag user in django? I have a field, and I want that only have a name, can be a tag to an existing user(search with @), or it can just a name(not existing user). In addition to this, I want to bring a user's card if it have @mention, and default card just for not existing user. Thanks in advance.
