insertOne

{
  doc: OptionalUnlessRequiredId<InferPureFieldsType>;
  relations?: TInsertRelations<TR>;
  options?: InsertOptions;
  projection?: Projection;
}

• The doc key receives an object of the pure values of the selected model. OptionalUnlessRequiredId type is the document type in the official MongoDB driver. You can read about it here.
• The relations key receives an object from the relations of this model. There is no relationship here. We will read about this in the next section.
• The options key gets the official MongoDB driver options to insertOne. You can read more about this here
• The projection key is used to receive written data. We use native projection in MangoDB. You can read MongoDB's own documentation here. In insertOne, you can only penetrate one step in relationships. Here you can get only pure fields because there is no relation. We will read more about this later.

The code

So this is all the code we've written so far (You can also see and download this code from here):

    
        const addCountryValidator = () => {
          return object({
            set: object(locationPure),
            get: coreApp.schemas.selectStruct("country", { users: 1 }),
          });
        };
        const addCountry: ActFn = async (body) => {
          const { name, population, abb } = body.details.set;
        
         return await countries.insertOne({
                        doc: {
                          name,
                          population,
                          abb,
                        },
                        projection: body.details.get,
                      });
    };
    coreApp.acts.setAct({
      schema: "country",
      actName: "addCountry",
      validator: addCountryValidator(),
      fn: addCountry,
    });


  

    
    {
      body: {
        _id: 65a24bd39e02c1041973ec21,
        name: testCountry,
        population: 90661541,
        abb: tc
      },
      success: true
    }
