How to iterate nested struct in Go?
问题
我收到一个错误消息，内容为“无法迭代范围...在花括号中的数据列表”。
我有以下结构体：
type FamilyMembers struct {XMLName xml.Name `xml:"familyMember" json:"familyMember"`Text string `xml:",chardata" json:",chardata"`ResponseCode string `xml:"responseCode"`Family []struct {Text string `xml:",chardata" json:",chardata"`Parents []struct {Text string `xml:",chardata" json:",chardata"`Parent []struct {Text string `xml:",chardata" json:",chardata"`FirstName string `xml:"firstName" json:"firstName"`MidleName string `xml:"midleName" json:"midleName"`SurName string `xml:"surName" json:"surName"`Gender string `xml:"gender" json:"gender"`DoB string `xml:"doB" json:"doB"`} `xml:"parent" json:"parent"`} `xml:"parents" json:"parents"`Children []struct {Text string `xml:",chardata" json:",chardata"`Child []struct {Text string `xml:",chardata" json:",chardata"`FirstName string `xml:"firstName" json:"firstName"`MidleName string `xml:"midleName" json:"midleName"`SurName string `xml:"surName" json:"surName"`Gender string `xml:"gender" json:"gender"`DoB string `xml:"doB" json:"doB"`} `xml:"child" json:"child"`} `xml:"children" json:"children"`} `xml:"family" json:"family"`}
我想将所有数据列在一个表格中，但我总是收到错误消息，指示在执行“body"时无法迭代范围......然后在控制台窗口显示所有数据和错误，如下所示：
{{ if .FamilyMembers }}<table><thead><tr><th>Names</th><th>Gender</th><th>Born</th></tr></thead><tbody>{{ range .FamilyMembers }}<tr><td>{{ .FirstName }} {{ .MidleName }} {{ .SurName }}</td><td>{{ .Gender }}</td><td>{{ .DoB }}</td></tr>{{ end }}</tbody></table>{{ else }}<h5 class="mt-3 text-center">No family details</h5>{{ end }}
我无法获得预期的结果，因为我尝试迭代时遇到问题。
英文:
I get erro message that "Range Cann't iterate over....list of data in Curl brackets"
I have the following struct
type FamilyMembers struct {XMLName xml.Name `xml:"familyMember" json:"familyMember"`Text string `xml:",chardata" json:",chardata"`ResponseCode string `xml:"responseCode"`Family []struct {Text string `xml:",chardata" json:",chardata"`Parents []struct {Text string `xml:",chardata" json:",chardata"`Parent []struct {Text string `xml:",chardata" json:",chardata"`FirstName string `xml:"firstName" json:"firstName"`MidleName string `xml:"midleName" json:"midleName"`SurName string `xml:"surName" json:"surName"`Gender string `xml:"gender" json:"gender"`DoB string `xml:"doB" json:"doB"`} `xml:"parent" json:"parent"`} `xml:"parents" json:"parents"`Children []struct {Text string `xml:",chardata" json:",chardata"`Child []struct {Text string `xml:",chardata" json:",chardata"`FirstName string `xml:"firstName" json:"firstName"`MidleName string `xml:"midleName" json:"midleName"`SurName string `xml:"surName" json:"surName"`Gender string `xml:"gender" json:"gender"`DoB string `xml:"doB" json:"doB"`} `xml:"child" json:"child"`} `xml:"children" json:"children"`} `xml:"family" json:"family"`}
I want to list all data in one table but i always get error message that excuting "body" ay <.FamilyMembers >: range cann't iterat over......then it dislay all data in console window with that error as following
{{ if .FamilyMembers }}<table ><thead><tr><th>Names</th><th>Gender</th><th>Born</th></tr></thead><tbody>{{ range .FamilyMembers }}<tr><td>{{ .FirstName }} {{ .MidleName }} {{ .SurName }}</td><td>{{ .Gender }}</td><td>{{ .DoB }}</td></tr>{{ end }}</tbody></table>{{ else }}<h5 class="mt-3 text-center">No family details</h5>{{ end }}
i can not get the expected results as i i tried to iterate
答案1
得分: 2
最后，通过在迭代中执行以下操作，我得到了我想要显示的内容：
{{ range $i, $a := .FamilyMembers.Family}}{{ range $j, $b := .Parents }}{{ range $k, $c := .Parent }}<tr><td>{{ .FirstName }} {{ .MidleName }} {{ .SurName }}</td><td>{{ .Gender }}</td><td>{{ .DoB }}</td></tr>{{ end }}{{ end }}{{ range $j, $b := .Children }}{{ range $k, $c := .Child }}<tr><td>{{ .FirstName }} {{ .MidleName }} {{ .SurName }}</td><td>{{ .Gender }}</td><td>{{ .DoB }}</td></tr>{{ end }}{{ end }}{{ end }}
通过这样做，可以帮助显示所有内部结构（嵌套结构）中的数据。
英文:
Finally, I got what i wanted to display by doing the following on iteration,
{{ range $i, $a := .FamilyMembers.Family}}{{ range $j, $b := .Parents }}{{ range $k, $c := .Parent }}<tr><td>{{ .FirstName }} {{ .MidleName }} {{ .SurName }}</td><td>{{ .Gender }}</td><td>{{ .DoB }}</td></tr>{{ end }}{{ end }}{{ range $j, $b := .Children }}{{ range $k, $c := .Child }}<tr><td>{{ .FirstName }} {{ .MidleName }} {{ .SurName }}</td><td>{{ .Gender }}</td><td>{{ .DoB }}</td></tr>{{ end }}{{ end }}{{ end }}
By doing that help to display data in all inner structs (nested structs)
