Reference Data Type

const schema = new Schema({ brand: { type: mongoose.Schema.Types.ObjectId } })

Options:-

• Required: If you choose this option, it means that users must fill in the required fields before submitting data to the database. This ensures that all necessary information is collected and avoids submitting incomplete data. It prompts users to provide input in the designated fields that must be filled.

Ex. It will not take blank fields in the database

• isPrivate: If you choose this option, it means that the system will keep the information entered in that field confidential and hidden from the user. This option is especially helpful when collecting sensitive data that should not be visible to the user.

Ex. It will not be visible to the user in the response

• isArray: If you choose this option, it means the selected field will be set up as an array. This option is helpful when storing multiple items as a single entity.

Ex. It will take an array in the field.

• unique: If you choose this option, it means that the system will require each value in that field to be different from the others. This is useful when you want to avoid duplicates in specific data fields.

Ex. when the user adds added value for that field, it won't allow taking that value again.

• Searchable: If you choose this option, it means that it can be used to search for specific information in the database by functioning as a query criterion. For example, if you mark a user’s name field as searchable, users can search for other users by their name.

Ex. we can search with this field for matching documents.

• Sortable: If you choose this option, it means that the field becomes eligible for use in sorting the elements of a collection resource in either ascending or descending order, enhancing the efficiency of data retrieval and organization.

Ex. it will sort the documents by selected field when we search the documents.

• Collection to Reference:- If you choose this option, it means that you can create a reference to another collection in the database that corresponds to a specific model type. This feature enables the establishment of more sophisticated data structures by connecting associated collections, resulting in enhanced data organization and accessibility which means that to organize and access related data more efficiently.

Ex: a collection which you want to give a reference in this field

• Reference Exist:- If you choose this option, it means that the system will verify if the referenced model item already exists in the database before creating the new model. This ensures that the data is accurate and reliable by confirming that all referenced items are valid and available before creating any new items.

• isAccessible:- If you choose this option, it means that the system will check if the referenced model item exists in the database and if the field is accessible. This helps to ensure data accuracy and security. This is particularly useful when data privacy is a concern and helps to ensure that only authorized users can access the referenced model item.
