Requests to my API contain an ID (required) and optional others fields such as name, email and username.
{
"id" : "12345",
"name" : "Bob",
"email" : "test@example.com"
}
After binding the request to a struct user if there isn't a user with the ID in my database I add them to it using:
user.App_id = appId
user.Created_at = (*tools.Timestamp)(&now)
user.Updated_at = (*tools.Timestamp)(&now)
_ = C.Database.C("users").Insert(&user);
but if there is a user I only want to update the fields that the request object includes but I'm not sure how to write the query.
My user struct uses pointers so that I can check for nil values
type user struct {
Id *string `bson:"id" json:"id"`
Name *string `bson:"name" json:"name"`
...
}
An update query that i've used elsewhere in my app looks like this:
err := collection("users").Update(bson.M{"id" : "user.Id"},bson.M{"$set": bson.M{"???":"???"}})
but I'm not sure how to construct the latter part of the query under these circumstances.
Note: I'm not using MongoDB's _id
