    I am using Django Rest Framework and have a model with a timestamp field that I want to group by. The outcome I would like is to have something like {tournament_count: 2, start_date: datetime object, tournaments: [{...tournaments model representations}]} I currently have a queryset returning the tournament_count and start_date but now I want to drop in the actual tournaments as well.

                    start_date=Trunc("time_stamp", "day", output_field=DateTimeField())

    I can't figure out a solution that will work well and scale well. Any thoughts?

    I am using django email message class ,and getting the above error ,any help is highly appreciated
    Just figured out the problem in case someone has read it. The system uses [ user_id, user_name ] as choices, not [ User instance, user_name ].

    @jameskomo From my experience I recommend thick Form or Serializer, but not implement signal

    Hi @yaguirre from medellin col :)
    Hi everyone! I’m a django beginner (generally a beginner dev)
    I have a question. I’m working through yet another guided project. This time Django Girls. In other projects, everyone simply put the app name into settings.py file, in INSTALLED_APPS. Django Girls did ‘blog.apps.BlogConfig’. What does the .app.BlogConfig part change? I assume it must be created as it’s a custom name, but is there any difference if I just put an app name?
    So in this case ‘blog’ vs. 'blog.apps.BlogConfig'
    qamarali This link will definitely help you out...

    @dotbrt What ever your PYTHON_PATH can read
    @dotbrt hi the "blog.app.BlogConfig" means from app.py in blog folder read the name if the app name.
    thisisshub Can somebody help me with "how to set the STATIC_ROOT in settings.py". I am trying to deploy my app on heroku but I keep getting error Error while running '$ python manage.py collectstatic --noinput'. even though I do have a STATIC_ROOT path in my setttings.py

    I have a dictionary which contains one item (“current_location”, which is a nested dict) and I would like to access that nested dict. However, I cannot use the key as the code will break if a different key is passed, e.g. “different_location".

    How can I access the first item in a dictionary without using a key? The dict looks like this:

    {'current_location': {'date': '2020-01-27T10:28:24.148Z', 'type_icon': 'partly-cloudy-day', 'description': 'Mostly Cloudy', 'temperature': 68.28, 'wind': {'speed': 10.48, 'bearing': 178, 'gust': 12.47}, 'rain_prob': 0.02, 'latitude': '-33.927407', 'longitude': '18.415747', 'request_id': 31364, 'request_location': 'Current location'}}

    Got it. I used dict[next(iter(dict))]

    Anyone who is familiar with using set.all in django in One-to-many relationship tables?

    I have these two models

    class Project(models.Model):
        project_name = models.CharField(max_length=100, blank=False)
        description = models.TextField(max_length=500, default=None)
        postedOn = models.DateTimeField(auto_now_add=True, blank=True)
        Owner = models.ForeignKey(User, on_delete=models.CASCADE)
        isCompleted = models.BooleanField(default=False)
        deadline = models.DateTimeField(blank=True, null=True)
        task_count = models.IntegerField(default=0)
        attachments=models.FileField(default='Project Attachments', upload_to='tasks_docs', validators=[validate_file_extension])
        def __str__(self):
            return self.project_name
    class Task(models.Model):
        task_name = models.CharField(max_length=50, blank=False)
        addedOn = models.DateTimeField(auto_now_add=True, blank=True)
        project = models.ForeignKey(Project, on_delete=models.CASCADE, default=1)
        rating = models.DecimalField(default=0, max_digits=2, decimal_places=1)
        amount = models.IntegerField(default=0)
        task_description = models.TextField(max_length=1000, default=None)
        task_link = models.URLField(blank=True)
        latest_submission_time = models.DateTimeField(blank=True, null=True)
        isCompleted = models.BooleanField(default=False)
        deadline = models.DateTimeField(blank=True, null=True)
        task_attachments=models.FileField(default='Tasks To Do', upload_to='tasks_docs', validators=[validate_file_extension])
        def __str__(self):
            return self.task_name

    And I am looking for a way to access tasks based on project. I can select a specific project and view its tasks

    @jameskomo try this:
    project = Project.objects.get(id=123).prefetch_related('task_set')
    you can also specify related_name for project property in Task

    Hi ,
    Is there anybody who can provide me some good resources for implement social authentication in Django-rest api?
    Thanks :)

    Supposed you have new feature that need geoDjango which is rely on postgist
    Will you add extension to existing database and work with it or split it out to be new microservice over REST API?

    Hi, I have a quick question.

    Say I have models called "Post" and "Reaction" and I have made a Post, saved it and now I want to react on it with a Reaction.
    Now, when I visit my feed where a list of Posts is, I want to show my reaction if I had one.

    Which means:
    {% if post.my_reaction %}{{ post.my_reaction.contents }}{% endif %}
    Now, obviously I want to load more than just one Post; posts which don't have my reactions on it.

    I know that I used to solve this with SQL in PHP with
    SELECT * FROM Post 
    LEFT JOIN Reaction ON Reaction.Post = Post.id
    How do I do this in Django ORM ??
