Below is my Advertiser Model -
type Advertiser struct {
ID int `json:"id" db:"id"`
CreatedAt time.Time `json:"created_at" db:"created_at"`
UpdatedAt time.Time `json:"updated_at" db:"updated_at"`
Name string `json:"name" db:"name"`
Email string `json:"email" db:"email"`
ContactNumber string `json:"contact_number" db:"contact_number"`
}
I have generated the Advertiser Resource and by default, it had brought-in the actions.
Now, in AdvertiserList action, I need all these fields to do some or the other calculation. But, finally, I would like to only respond with Name, Email and ContactNumber fields.
Remember, this is a List action, which means, we have an array of Advertiser.
Right now, my action does below-
func (v AdvertisersResource) List(c buffalo.Context) error {
tx, ok := c.Value("tx").(*pop.Connection)
if !ok {
return errors.WithStack(errors.New("no transaction found"))
}
advertisers := &models.Advertisers{}
q := tx.PaginateFromParams(c.Params())
if err := q.All(advertisers); err != nil {
return errors.WithStack(err)
}
c.Set("pagination", q.Paginator)
return c.Render(200, r.JSON(advertisers))
}
