                      QUESTION

                      mongoose — Array variable in query

                      Asked 2022-Apr-05 at 12:10

                      I'm trying to write a mongoose query that allows me to find a document with a populated array, where the name of the array is stored in a variable. I've tried various syntaxes, using [square brackets], etc, and I've searched but can't find anything that works.

                      var arrayName = req.params.abbreviation + "Films";
                      console.log(arrayName); //documentaryFilms
                      
                      FilmModel.findOne({
                        $and: [
                          { incomplete: false },
                          { [arrayName].[0]: { $exists: true } }
                      ...
                      

                      Does anyone know how this can be achieved? Thank you

                      Use the $size operator to get the length of the array.

                      FilmModel.aggregate(
                      [
                           {
                             $addFields: {
                              "size_of_array": {
                                $size: "$abcFilms"
                              }
                             }
                           }
                           { 
                             $match: { "size_of_array": { $gt: 0 } } 
                           }
                      ])
                      

                      If you want to filter based on an element with index n in an array take a look at $arrayElemAt operator.
