我正在嘗試使用 Golang、Gin 和 GORM 構(gòu)建一個簡單的 CRUD 博客。但是，當我想更新博客內(nèi)容時，觸發(fā)了以下錯誤：reflect: call of reflect.Value.SetString on uint Value/usr/local/go/src/reflect/value.go:223 (0x10bfb25) flag.mustBe: panic(&ValueError{methodName(), f.kind()})/usr/local/go/src/reflect/value.go:2292 (0x10bfaa3) Value.SetString: v.mustBe(String)/Users/sam/go/pkg/mod/gorm.io/gorm@v1.23.5/schema/field.go:771 (0x144fcfc) (*Field).setupValuerAndSetter.func11: field.ReflectValueOf(ctx, value).SetString(data)/Users/sam/go/pkg/mod/gorm.io/gorm@v1.23.5/callbacks/update.go:144 (0x14b7d9a) ConvertToAssignments.func2: field.Set(stmt.Context, stmt.ReflectValue, value)/Users/sam/go/pkg/mod/gorm.io/gorm@v1.23.5/callbacks/update.go:275 (0x14b62fa) ConvertToAssignments: assignValue(field, value)/Users/sam/go/pkg/mod/gorm.io/gorm@v1.23.5/callbacks/update.go:73 (0x14b4fe4) Update.func1: if set := ConvertToAssignments(db.Statement); len(set) != 0 {/Users/sam/go/pkg/mod/gorm.io/gorm@v1.23.5/callbacks.go:130 (0x146d632) (*processor).Execute: f(db)/Users/sam/go/pkg/mod/gorm.io/gorm@v1.23.5/finisher_api.go:372 (0x1476811) (*DB).Updates: return tx.callbacks.Update().Execute(tx)/Volumes/Data/Develop/Go/go-blog/controllers/blog.go:65 (0x1693364) UpdateBlog: models.DB.Model(&blog).Updates(input)/Users/sam/go/pkg/mod/github.com/gin-gonic/gin@v1.7.7/context.go:168 (0x168a121) (*Context).Next: c.handlers[c.index](c)/Users/sam/go/pkg/mod/github.com/gin-gonic/gin@v1.7.7/recovery.go:99 (0x168a10c) CustomRecoveryWithWriter.func1: c.Next()/Users/sam/go/pkg/mod/github.com/gin-gonic/gin@v1.7.7/context.go:168 (0x1689246)

這可能是因為您使用的結(jié)構(gòu)不同于 models.Blog 來更新。您可以嘗試以下操作嗎：
func UpdateBlog(c *gin.Context) {
var blog models.Blog
if err := models.DB.Where("id = ?", c.Param("id")).First(&blog).Error; err != nil {
c.AbortWithStatusJSON(http.StatusNotFound, gin.H{"error": "record not found"})
return
}
var input UpdateBlogInput
if err := c.ShouldBindJSON(&input); err != nil {
c.AbortWithStatusJSON(http.StatusBadRequest, gin.H{"error": err.Error()})
return
}
updateBlog := models.Blog{Title: input.Title, Content: input.Content}
models.DB.Model(&blog).Updates(&updateBlog)
c.JSON(http.StatusOK, gin.H{"data": updateBlog})
}
