How do I sort the movies according to their star ratings and filter the movies with lower rating tha-CodePudding

I want to sort the movies according to their star ratings and filter the movies with lower rating than the specified threshold. I want to sort movie and TV information in descending order by stars, search by each ID, and display data.json format and socre. However, I get a'module' object does not support item assignment error. context ["movie"] = in movie_list

class Movie(models.Model):
    id = models.CharField(primary_key=True, editable=False,
                          validators=[alphanumeric],max_length = 9999)
    stars = models.FloatField(
                    blank=False,
                    null=False,
                    default=0, 
                    validators=[MinValueValidator(0.0),
                     MaxValueValidator(10.0)]
                     )
    def get_comments(self):
        return Comment_movie.objects.filter(movie_id=self.id)
    
    def average_stars(self):
        comments = self.get_comments()
        n_comments = comments.count()

        if n_comments:
            self.stars = sum([comment.stars for comment in comments]) / n_comments
        else:
            self.stars = 0
        return self.stars
class TV(models.Model):
    id = models.CharField(primary_key=True, editable=False,
                          validators=[alphanumeric],max_length = 9999)
    stars = models.FloatField(
                    blank=False,
                    null=False,
                    default=0, 
                    validators=[MinValueValidator(0.0),
                     MaxValueValidator(10.0)]

        return self.stars

CodePudding user response：

If I understand correctly, you should have imported context as a module. If so then the error arises because you are essentially trying to index a module in

context["movie"]

this is not supported in python. Say you are trying to store the movies in a 'movies' dictionary in the module, then what you should do is:

import context
...
context.movies["movie"] = movie_list

But I think the module would probably have a method returning the dictionary you need, then you can use:

import context
...
movies = context.some_method()
movies["movie"] = movie_list

Same for the tv list.
