With gorm after the search, is empty or query to but the OtherPage displays is null, the front end, according to the how to OtherPage assignment is empty, let the front-end display []

CodePudding user response:

Null pointer and empty array object is not the same as
Or you could define the OtherPage as arrays,
Namely OtherPage [] Page
Either through myPage, judge OtherPage is nil is assigned an empty array
The
For _, v:=range myPage {
If v.O therPage=nil {
V.O therPage=[...]. * Page {}
}
}

CodePudding user response:

For OtherPage [] Page also not line, or returns null, I used gorm query
Results in OtherPage no value, it shows that Null, is there a better way
