Is there a way to pass certain info, that is specific to a user, to the fields of a (new) django form?
I have the following "problem": I have automated a "prediction-game" where users can win points when they predict the correct winners in a sports event over multiple weeks (for example: Tour de France). They are allowed to choose 5 athletes of which they think that will win in the races. At the end of every week, the users are allowed to make some changes in their prediction for the next week. Until a certain date (start of the event or week), the users can choose athletes for their prediction. The users can fill in the form and if they change their minds before the start, they are still able to change/update their prediction. But after the start, they can't change it anymore and their input will be used to calculate their score. After the first week (in which their scores are calculate with the input they made in the "PredictionWeek1" model), they will have a change to make a new prediction for the next week ("PredictionWeek2" model) for which they also have the change to update it as much as they want before a certain date. In reality, the input for the second week, will be very similar to the … -
Django - How to make UNIQUE constraint not apply across inherited models?
There's a PlainModel that has attributes like name, color - and a slug, which has to be unique. I want to make my own version of it, an ExtendedModel that also has size. So, I made the model inherit from PlainModel: class ExtendedModel(PlainModel): size = models.IntegerField(...) However, I ran into an issue - because of the way Django model inheritance works, ExtendedModel's database table only has two columns - one for size, and one for a pointer to the original PlainModel table. This means that the unique constraint on slug applies for both models, and there can't be an ExtendedModel with the same slug as an already existing PlainModel. I don't want this behavior, the slugs are only going to ever appear in the context of each model separately (e.g. /products/{slug} and /products/extended/{extended_slug}), so there's no reason to ensure uniqueness across them both. Is it possible to make the constraint apply only for each model respectively? An obvious way would be to have the tables be completely separate, which Django does not seem to support, however. PlainModel would have to be an "Abstract Model", which I can't control. (PlainModel is defined in an external library.) Another way would be to … -

Is a subquery of this kind possible in django?
In sql I could can do something like this - select a, b, c from ( select a, b, c from table_a ) where a = something Is this possible with django? I've only ever used subquery of the type where the primary key of the subquery for example maps to a column of a row in the parent query. I don't want this though on this occasion. Here is the context. I have a query which has annotated column which uses a Window frame. Such an expression cannot be included in a WHERE clause because sql evaluates the where clause first. So it is necessary to perform this query first as a subquery and then use the result like it is its own table. On this parent query I can then filter. -
