Pagination(&userList, requestParams.Page, global.Cfg.Server.DefaultPageSize)
return pagination, errNote:
There is a slight difference between the struct defined by the preload method and the struct defined by the joins query. The name of the struct defined by the preload method must be consistent with the name of the struct for the current table of the model. Also, the name of the struct for the associated table cannot be the same as the name of the struct for the model. For example, the definition of "UserInfo" is as follows:
Definition of receiving a struct.
type BaseUser models.GinUser
type GinUserInfo models.GinUserInfo
type GinUser struct {
BaseUser
UserInfo GinUserInfo `gorm:"foreignKey:user_id" json:"user_info"`
}Usage instructions as follows:
var userList = make([]user.GinUser, 0)
pagination, err := paginator.NewBuilder().
WithDB(global.DB).
WithModel(models.GinUser{}).
WithPreload("UserInfo").
Pagination(&userList, requestParams.Page, global.Cfg.Server.DefaultPageSize)
return pagination, errThis method does not recommend using WithFields or WithField to query fields. Instead, it is recommended to directly define the query fields specified by the receiving struct.

View usage.
WithDB(db *gorm.DB) *PageBuilderWithModel(model interface{}) *PageBuilderPass the main table model as a parameter for the query, for example: models.GinAdmin. You cannot pass a structure address as a parameter, like &models.GinAdmin.
WithField(fields []string) *PageBuilder The last parameter of "fields" defaults to "_select" (can be omitted), but if "_omit" is passed, it filters out the fields transmitted earlier.
Note:
- _select / _omit must be the last parameters.
- WithModel parameter cannot be passed as a pointer to a struct. For example: &models.GinAdmin must be models.GinAdmin, otherwise the _omit parameter will be ineffective.
- This note applies to the WithFields method and WithMultiFields method.
Usage as follows:
// Indicates filtering of front fields.
WithField([]string{"created_at", "updated_at", "_omit"})
// Indicates the fields to be queried.
WithField([]string{"created_at", "updated_at", "_select"})
WithField([]string{"created_at", "updated_at"})4）Not necessary in chain operations. Multi-table queries or filtering field methods (when using the preload mode, there may be issues with associated table queries, and it is not recommended to use the preload association query method).
WithFields(model interface{}, table string, fields []string) *PageBuilderThe last argument for fields is default to "_select" (can be omitted), if "_omit" is passed, it will filter the fields transmitted earlier.
Usage as follows：
// Indicates filtering the preceding field.
WithFields(models.GinUser{}, models.GinUserTbName, []string{"password", "salt", "_omit"})
// "Indicates the field before the search."
WithFields(models.GinUserInfo{}, models.GinUserInfoTbName, []string{"id", "user_id", "role_ids", "_select"})
WithFields(models.GinUserInfo{}, models.GinUserInfoTbName, []string{"id", "user_id", "role_ids"})5）Not necessary in chain operations. Multiple table and field queries (can replace WithFields method)
WithMultiFields(fields []SelectTableField) *PageBuilderUsage as follows：
WithMultiFields([]paginator.SelectTableField{
{Model: models.GinUser{}, Table: models.GinUserTbName, Field: []string{"password", "salt", "_omit"}},
{Model: models.GinUserInfo{}, Table: models.GinUserInfoTbName, Field: []string{"id", "user_id", "role_ids"}},
})6）Not necessary in chain operations. Multiple table association query with proactive preloading (conditions not currently supported).
WithPreloads(querys []string) *PageBuilder Usage as follows：
WithPreloads([]string{"UserInfo", "UserRecord"})7）Not necessary in chain operations. Active preloading of associated queries (can pass conditions, conditions refer to Gorm).
WithPreload(query string, args ...interface{}) *PageBuilderUsage as follows：
WithPreload("UserInfo", "user_id = ?", "1")WithCondition(query interface{}, args ...interface{}) *PageBuilderPass in query conditions that support the querying format used in the 'where' conditions in GORM (non-struct format). The 'query' and 'args' parameters should follow the same method of passing in 'where' conditions as in GORM.
WithJoins(joinType string, joinFields []OnJoins) *PageBuilderjoinType: Type of join. It can be left, right or inner. joinFields structure: LeftTableField, such as the main table's ID, and RightTableField, such as the related table's main table ID.
Usage as follows：
WithJoins("left", []paginator.OnJoins{{
LeftTableField: paginator.JoinTableField{Table: models.GinUserTbName, Field: "id"},
RightTableField: paginator.JoinTableField{Table: models.GinUserInfoTbName, Field: "user_id"},
}})Pagination(dst interface{}, currentPage, pageSize int) (Page, error)"dst" is a "struct" structure that receives incoming data. Note: It must be passed in application mode, such as "&userList". "model" and "currentPage" represent the current page number, and "pageSize" represents the number of queries per page.
NewDB() *gorm.DBAfter using this method, all methods inside the pagination for chained operations are unavailable. You can continue using the native methods of GORM afterwards.
Usage as follows：
NewDB().Where("id = ?", id).First(&userList)paginator.CurrentPagepaginator.Listpaginator.Totalpaginator.LastPagepaginator.PerPageUploadFile(path string, r *gin.Context) (*FileHeader, error)By default, the files are stored in the "upload" directory of the project. If it does not exist, it will be created automatically. The path will be "upload" directory module directory, such as "user". The directory structure will be "upload/user/{yyyy-mm-dd}/...".
Usage as follows：
app/controller/backend/attachment.go
pkg/util/upload.go
router/routes/common.go
Configure the amqp parameters in the yaml configuration file.

# MacOS Installation
brew install golang-migrate
# Install Window with scoop https://scoop.sh/
scoop install migrate
# "Creating migration file syntax, for example:"
migrate create -ext sql -dir migrations -seq create_users_table
# The first way to execute migration.
# Carrying out migration operation:
migrate -database 'mysql://root:123456@tcp(127.0.0.1:3306)/gin_framework' -path ./migrations up
# Performing rollback operation:
migrate -database 'mysql://root:123456@tcp(127.0.0.1:3306)/gin_framework' -path ./migrations down
# The second way to perform migration.
# View help command.
go run main.go migrate --help
# The format is as follows：
go run main.go migrate -s {step} -e {env}
# env: Keep consistent with the config.*.yaml file among dev, test, and prod. The default is dev.
# step: The number of migration files to be executed (or rolled back), for example, 1, 2, 3... If you want to execute all, use "all".
# Perform all migration operations:
go run main.go migrate -s all
# Perform partial migration operations：
# eg.：go run main.go migrate -s 1
# Performing rollback operation：
# eg.：go run main.go migrate -s -1# Execute the command to generate all models.
go run main.go model -tb=all {env}
# Please refer to the help for specific parameters.
go run main.go model -helpgo run main.go controller -c={controller name} -m={module name}
# eg.：go run main.go controller -c=admin -m=backend
