What are other real-world and useful usages of model managers other than filtering?
This is my first time learning Django Model Mangers. I saw videos on YouTube and answers on SO. Everywhere I see they are using model managers for filtering like: example: class BlueManager(models.Manager): def get_query_set(self): return super(BlueManager, self).get_query_set().filter(colour='Blue') class MyModel(models.Model): colour = models.CharField(max_length=64) blue_objects = BlueManager() another example: class AvailableBookManager(models.Manager): def get_query_set(self): return super(AvailableBookManager, self).get_query_set().filter(availability=1) class Book(models.Model): (...)#fields definition objects = models.Manager() #default manager available_objects = AvailableBookManager() #own manager here, I can use books = Book.objects.filter(available=1). Why do I make it so complicated? third example: class BookManager(models.Manager): def title_count(self, keyword): return self.filter(title__icontains=keyword).count() class Book(models.Model): title = models.CharField(max_length=100) publication_date = models.DateField() num_pages = models.IntegerField(blank=True, null=True) objects = BookManager() # The Custom Manager. def __unicode__(self): return self.title These examples are good for understanding what is model manager? but they aren't useful. Some of these examples is against Simple is better than complex, if I can do a simple filter with one line of code why do I have to make a model manager with 5 or 6 line of codes and do that same thing. Can you please help me out understand this by providing more useful and real-world examples.I hope you help me, thank you. -
Django query if field has chosen
I have 2 models : ServiceRequest and Quote like this: class ServiceRequest(models.Model): post_time = models.DateTimeField(default=timezone.now) class Quote(models.Model): service_request = models.ForeignKey(ServiceRequest, on_delete=models.CASCADE) status = models.BooleanField(default=False) My question is: how to get queryset from ServiceRequest can know one of Quote has status is True ? Example : ServiceRequest id = 1 , have 2 Quote. One status is True and one is False. ServiceRequest id = 2 have 2 Quote, both them status is False. I want id=1 return True, and id=2 return False Thank you -
How to resolve the "psycopg2.errors.UndefinedTable: relation "auth_user" does not exist" when running django unittests on Travis
I'm using Travis for CI/CD as part of my Django app, with a postgresql database. (Django 2.1.4) The build consistently fails on Travis as soon as the tests run.

Django template filters
Which filter should i use in django templates in order to display my text in the way it was entered including all the spaces and even alignments(whether it's Left, Right etc) For eg: I want to add some description about a title and i want it to be in this form: "My my, 2018 is going by so quickly! Maybe it went by fast because we were too busy loading up on all kinds of yummy food at all the new restaurants that opened up. As usual, we took the liberty of curating a list of eateries that we think you should not keep waiting. So, without much further adieu, there’s your Culinary Bucket List For The Rest Of 2018". Currently my title description is set in this format : {{value:Linebreaks}} -

Django deserialize to model instance without saving to DB
I want to serialize an object to Json, then deserialize it as the object, without save it to DB (it's already saved). The reason is that the current state of the model may be different from the state when I serialized it. This is how I currently serialize the object: ser_obj = serializers.serialize("json", [self.instance]) Now, as I understand, in order to deserialize I can do something like: for obj in serializers.deserialize("json", ser_obj): obj.save() But that will save the object to DB, which I don't want to. I guess I can also do something like: MyModel(field1 = ser_obj['field1'], field2 = ser_obj['field2'] ) But it seems wrong. So any idea how can I deserialize json object into Django model without saving to DB? -
Collapse .data-target doesn't work when setting the target id, or even target class, with data from Django template tag
I'm trying to collapse some content rendered in a for loop via Django template tag using bootstrap. If I hard code the collapse target, either as a Class target (data-target=".someclass") or href (href=#sometarget) I can get the function to work. However, since its a for loop, I need different targets for each 'item' so when I try and use dynamic/unique data from database as the target, bootstrap fails to collapse the content.
