GORM unable to query all records using .Find()-CodePudding

I am trying to write a function to query all results that match a set of conditions and save them in a struct slice.

// Queries the database for the given set of fields and some string conditions specified as a map
func QueryAllRecords(db *gorm.DB, outputObject interface{}, conditions map[string]interface{}) {

    result := db.Where(conditions).Find(&outputObject)
    if result.Error != nil {
        panic(result.Error)
    }
    log.Println(Utils.CreateLogMessage("Queried all records", outputObject))
}

According to the GORM docs (https://gorm.io/docs/query.html#Retrieving-all-objects), I can query all records using the .Find() function and then specify the struct where the output of the query will be saved.

This is where I make my function call to QueryAllRecords:

var outputObject []Models.Product
conditions := map[string]interface{}{"name": "Sample Product"}

DB.QueryAllRecords(db, outputObject, conditions)
fmt.Println(outputObject)

When I try to print outputObject, I get an empty an empty slice []. It seems like the .Find(&outputObject) is not saving the result in the slice like I want it to. I can successfully print outputObject within the function itself, but not after it has returned.

CodePudding user response：

Use the DB.QueryAllRecords(db, outputObject, conditions) instead

CodePudding user response：

Pass the reference/pointer of the outputObject array to QueryAllRecords, or return it from the function.

I can successfully print outputObject within the function itself, but not after it has returned.
