How to add a share button in Django to share a post
I am relatively new to Django, I have a blog that I have been working on. However, I am having problem implementing a sharing button to share my posts on social media, with the title and thumbnail,specifically Facebook and WhatsApp.I have researched and googled all the possible solutions, but neither of them tends to solve my problem. Not many tutorials out here have covered this issue. I have used the social_share,django_addthis, and social_share_widgets but none of them seem to help. Here are my models and templates {% extends 'base.html' %} {% load static %} {% load social_share %} {% load blog_tags %} {% block content %} <p>{{post.content| safe}}</p> <div class="social-contact"> <a href="#" id="shown" style="background-color: red;"><i class="fa fa-share"></i> Share</a> <a id="hidden" href="https://facebook.com/share?url=http://devbrian.com{{ request.get_full_path|urlencode }}" class="facebook-link"><i class="fa fa-facebook"></i> Facebook</a> <a id="hidden" href="https://www.twitter.com/share?url=http://devbrian.com{{ request.get_full_path|urlencode }}" class="twitter-link"><i class="fa fa-twitter"></i> Twitter</a> <a id="hidden" href="https://www.instagram.com/share?url=http://devbrian.com{{ request.get_full_path|urlencode }}" class="instagram-link"><i class="fa fa-instagram"></i> Instagram</a> <a style="background-color: green;" href="https://api.whatsapp.com/send?+254799043853=+*YOURNUMBER*&text=%20*{{ request.get_full_path|urlencode }}&title=<your title>&summary=<your desc>&source=http://devbrian.com*" class="youtube-link"><i class="fa fa-whatsapp"></i> Whatsapp</a> </div> {% endblock content %} class Post(models.Model): author = models.ForeignKey(User,on_delete=models.CASCADE) title = models.CharField(max_length=200) slug = models.SlugField(max_length=200,blank=True,unique=True) thumbnail = models.ImageField() def get_absolute_url(self): return reverse('details', kwargs={'slug': self.slug}) I will appreciate your help -

Convert postgres raw query to Django ORM query and group by
I have a raw Postgresql query which needs to be converted to Django ORM query. I was able to execute the query in Postgres and see the expected result.

Cannot get cookie value
I have a script that calls a prompt when I push a button and gets a number from the user. The number is stored in a cookie.

Add user to a group at signup in Django
New to Django here. There are three types of users: Bronze, Silver and Gold with different permissions. All users start out as Bronze when they sign up and then move upwards when they fulfill certain conditions. Therefore I tried to customize the User model using Django's tutorial. So far I have been able to create the users correctly. However, I want to now add these users to the Bronze group as soon as they sign up and am not sure where do I put that code. Here is my code.

Django: How to use custom url name instead of 'password_reset_done' for password reset route in urls.py?
I am creating my first Django project and implementing password-reset functionality. So I know that I have to configure the URLs with the following name and use inbuilt views. password_reset password_reset_done password_reset_confirm password_reset_complete But I have created a seaparate application accounts to handle the authentication part and I am following a convention of prepending application name for naming application-specific URLs. So all the URLs in the accounts app have accounts- prepended to them. path('signup/', views.signup, name='accounts-signup'), path('logout/', auth_views.LogoutView.as_view(), name='accounts-logout'), PROBLEM: But while creating password reset URLs, I have to use predefined names as mentioned above. Is there a way to use a custom name in place of these predefined names, or any way to override these in settings.py I checked docs for settings.py but could not find anything. EXPECTATION: I want to be able to assign custom names like accounts-password_reset and accounts-password_reset_done. The app works fine with predefined names, but what If I want to create another app in the same project with a separate authentication system and separate routes. Wouldn't the same name for reset password route can cause namespace collisions in other apps? -
Can I add a Color Picker to Django Forms
I tried using the django-colorfield module which works great for the admin page but I cannot get it to render the widget in the actual forms. Below is what I have tried so far and all I get on the form is a CharField with the default value as text. I am open to every and any suggestions but I do not want to use the RGB color picker that html5 has if possible.

Using a Wagtail "ChoiceBlock" with dynamic choices rather than a hardcoded list
We have a setup with a Blog model that has a manytomany relation for BlogPageCategory, and we have a "recent blog posts" streamfield block that lets you specify whether to show cards for X latest blog posts, or X latest blog posts from a specific category. As such, we started with the following code: from wagtail.core import blocks class RecentBlogEntries(blocks.StructBlock): title = blocks.CharBlock( required=True, ) category_filter = blocks.ChoiceBlock( label='Filter by Category', required=False, choices=[ ('all', 'All'), ('First Category', 'First Category'), ('...',. '...'), ], ) ... But hardcoding the categories is kind of silly, and being able to pick them from "what the list is, right now, based on the CMS data for BlogPageCategory" would be far more convenient. However, the following code (of course) turns into an equally hardcoded migration: from wagtail.core import blocks from ... import BlogPageCategory class RecentBlogEntries(blocks.StructBlock): title = blocks.CharBlock( required=True, ) choices = [ (cat.name, cat.name) for cat in BlogPageCategory.objects.all()] choices.sort() choices.insert(0, ('all', 'All')) category_filter = blocks.ChoiceBlock( label='Filter by Category', required=False, choices=choices, ) ... Is there any way to make this a dynamic value instead of a list that is fixed by makemigrations? -
