gormcls - Isolate the scope of temporary variables when using GORM, making the code more concise

gormcls isolates the scope of temporary variables when working with GORM, simplifying database operations and making the code more concise.

gormcls works in conjunction with gormcnm and gormcngen, simplifying GORM development and optimizing the management of temporary variable scopes.

Quick Start

Example Code

Query Data

var example Example
if cls := gormcls.Cls(&Example{}); cls.OK() {
	err := db.Table(example.TableName()).Where(cls.Name.Eq("test")).First(&example).Error
    must.Done(err)
    fmt.Println("Fetched Name:", example.Name)
}

Update Data

if one, cls := gormcls.Use(&Example{}); cls.OK() {
    err := db.Model(one).Where(cls.Name.Eq("test")).Update(cls.Age.Kv(30)).Error
    must.Done(err)
    fmt.Println("Age updated to:", 30)
}

Get Maximum Value

var maxAge int
if one, cls := gormcls.Use(&Example{}); cls.OK() {
	err := db.Model(one).Select(cls.Age.COALESCE().MaxStmt("max_age")).First(&maxAge).Error
	must.Done(err)
    fmt.Println("Max Age:", maxAge)
}

API Overview

Function	Param	Return	Description
Cls	MOD	CLS	Returns the column information (cls), useful when only column data is needed.
Use	MOD	MOD, CLS	Returns the model (mod) and its associated columns (cls), ideal for queries or operations that need both.
Umc	MOD	MOD, CLS	Returns the model (mod) and its associated columns (cls), functioning identically to the Use function.
Usc	MOD	[]MOD, CLS	Returns a slice of models (MOD) and the associated columns (cls), suitable for queries returning multiple models (e.g., Find queries).
Msc	MOD	MOD, []MOD, CLS	Returns the model (mod), the model slice ([]MOD), and the associated columns (cls), useful for queries requiring both model and column data.
One	MOD	MOD	Returns the model (mod), ensuring type safety by checking whether the argument is a pointer type at compile-time.
Ums	MOD	[]MOD	Returns a slice of models (MOD), useful for queries that expect a slice of models (e.g., Find queries).
Uss	-	[]MOD	Returns an empty slice of models (MOD), typically used for initialization or preparing for future object population without needing the columns.
Usn	int	[]MOD	Returns a slice of models (MOD) with a specified initial capacity, optimizing memory allocation based on the expected number of objects (MOD).
