英文:
Go gota Dataframe not loading struct, requires []struct
问题
我正在阅读一个文件，每一行都包含两个由空格分隔的单词。我扫描并拆分每一行，将两个单词（字符串）存储在MyEntity结构体（在items中）。然后将这些单词添加到items中。
type Entity struct {
Name string
Entity string
}
type MyEntity struct {
Entities []Entity
}
func (entity *MyEntity) AddEntity(item Entity) []Entity {
entity.Entities = append(entity.Entities, item)
return entity.Entities
}
...
items := MyEntity{}
// 在这里循环遍历行 - 名称是第一个单词，实体是第二个单词
item := Entity{
name, entity,
}
items.AddEntity(item)
...
这里的items不应该是[]struct吗？我正在使用gota包（https://github.com/go-gota/gota）从items创建一个DataFrame，但是使用dataframe.LoadStructs(items)失败，因为items是一个struct，而它必须是一个[]struct。
我对Go还比较新手，所以我在这里漏掉了什么？
英文:
I am reading a file with each row containing two words separated by a space. I scan and split each line to two words (strings) and store them in the MyEntity struct (in items). The words are then added to items.
type Entity struct {
Name string
Entity string
}
type MyEntity struct {
Entities []Entity
}
func (entity *MyEntity) AddEntity(item Entity) []Entity {
entity.Entities = append(entity.Entities, item)
return entity.Entities
}
...
items := MyEntity{}
// loop here over the rows - name is first word, entity is second word
item := Entity{
name, entity,
}
items.AddEntity(item)
...
Should items not be a []struct here? I am using the gota package (https://github.com/go-gota/gota) to create a DataFrame from items but using dataframe.LoadStructs(items) fails because items is a struct and it must be a []struct.
I am fairly new to Go, so what am I missing here?

得分: 1
从实体切片加载数据框：
df := dataframe.LoadStructs(items.Entities)
英文:
Load the data frame from the slice of entities:
df := dataframe.LoadStructs(items.Entities)
