Does anyone have an idea how I could modify this code so that I can search based on title or rating or both? I've tried several approaches, including using the $and operator, with no success
static async getMovies({
filters = null,
page = 0,
moviesPerPage = 20,
} = {}) {
let query = {}
if (filters) {
if ("title" in filters) {
console.log(filters["title"]);
query.title = { $regex: filters["title"], $options: "i" };
} if ("rated" in filters) {
query.rated = { $eq: filters["rated"] };
}
}
let cursor
try {
cursor = await movies.find(query)
.limit(moviesPerPage)
.skip(moviesPerPage * page);
const moviesList = await cursor.toArray();
for (let i = 0; i < moviesList.length; i++) {
const movie = moviesList[i];
const movieReviews = await reviews
.find({ movie_id: movie._id })
.toArray();
movie.review = movieReviews;
}
const totalNumMovies = await movies.countDocuments(query);
return { moviesList, totalNumMovies };
} catch (e) {
console.error(`无法发出查找命令,${e}`);
return { moviesList: ["error"], totalNumMovies: 0 };
}
}
If you want to search based on name or rating, or both, you can simply use the query below. You don't need to use the $eq operator with rated filters. Mongoose's find function will match the value directly without using the $eq operator.
if (filters?.title) { query.title = { $regex: `^${filters.title.replace(/[-[\]{}()*+?.,\/^$|#\s]/g, "\$&")}`, $options: "i" } } if (filters?.rated) { query.rated = filters.rated } console.log(query)
