I am new to golang and I'd like to aggregaet query results into a results
slice to be pushed to the browser. Here is the code:
type Category struct {
Id bson.ObjectId `bson:"_id,omitempty"`
Name string
Description string
Tasks []Task
}
type Cats struct {
category Category
}
func CategoriesCtrl(w http.ResponseWriter, req *http.Request) {
session, err := mgo.Dial("localhost")
if err != nil {
panic(err)
}
defer session.Close()
session.SetMode(mgo.Monotonic, true)
c := session.DB("taskdb").C("categories")
iter := c.Find(nil).Iter()
result := Category{}
results := []Cats //Here is the problem
for iter.Next(&result) {
results = append(results, result)
fmt.Printf("Category:%s, Description:%s
", result.Name, result.Description)
tasks := result.Tasks
for _, v := range tasks {
fmt.Printf("Task:%s Due:%v
", v.Description, v.Due)
}
}
if err = iter.Close(); err != nil {
log.Fatal(err)
}
fmt.Fprint(w, results)
}
But instead I get
type []Cats is not an expression
How can I fix this?
