我希望有人能够帮助我。我已经开始构建一个网络应用程序,并决定使用 GO 和 Revel。到目前为止,我已经学到了很多东西,但是我似乎无法使用这一功能。我有以下代码:

package controllers

import (
"github.com/revel/revel"
_ "github.com/denisenkom/go-mssqldb"
"database/sql")

type App struct {
*revel.Controller
}

type resultRow struct {
TransactionDomain string
TransactionType string
TransactionIsoResponse string
Store string
Terminal string
Vendor string
RequestDT string
ResponseDT string
AccountDisplay string
AccountDetails1 string
InvoiceNumber string
Amount string
}

type colNames struct {
Name string
}

type resultTable struct {
fpk string
columns []colNames
resultRows []resultRow
}
func (c App) FpkTable() revel.Result {
//all db section goes here. I have confirmed the results are obtaind back 
//from the db.
    err = rows.Scan(&resRow.TransactionDomain,
        &resRow.TransactionType,
        &resRow.TransactionIsoResponse,
        &resRow.Store,
        &resRow.Terminal,
        &resRow.Vendor,
        &resRow.RequestDT,
        &resRow.ResponseDT,
        &resRow.AccountDisplay,
        &resRow.AccountDetails1,
        &resRow.InvoiceNumber,
        &resRow.Amount)
    if err != nil {
        revel.INFO.Println("Scan failed:", err.Error())
    }
    arrRow = append(arrRow, resRow)
}
columnNames := []colNames{{Name:"Domain"}, {Name:"Type"}, {Name:"Vendor Response"}, {Name:"Store"}, {Name:"Register"}, 
{Name:"Request DT"}, {Name:"Response DT"}, {Name:"Account"}, {Name:"Token"}, {Name:"Invoice"}, {Name:"Amount"}}
table := &resultTable{c.Request.FormValue("store") + "-" + c.Request.FormValue("register") + "-" + c.Request.FormValue("invoice") + "-" + c.Request.FormValue("date"), columnNames, arrRow}
return c.Render(table)

我有以下html模板:

<div class="row">
    <a>{{.fpk}}</a>
    <ul>
        {{range .columns}}
        <li>{{.Name}}</li>
        {{end}}
    </ul>
</div>

我期待看到这样的东西

<div class="row">
    <a>AAA-BBB-CCC-DDD</a>
    <ul>
        <li>Domain</li>
        <li>Type</li>
        .
        .
        .
    </ul>
</div>

但是相反,我没有将任何值传递到模板中

 <div class="row">
    <a></a>
        <ul>

        </ul>
        ::after
        //This line makes me believe the processing of the
        //template is being done properly except the data 
        //is not being passed properly to the template.
 </div>

我浏览了所有可能的网站,对此感到疑惑,但我无法找到解决方案。

我相信这会很简单,但无论如何,感谢您提供的任何帮助。

我不确定您的模板语法,通常我会这样做:

<div class="row">
    <a>{{.fpk}}</a>
    <ul>
        {{range $index, $element := .columns}}
        <li>{{$element.Name}}</li>
        {{end}}
    </ul>
</div>

我能想到的另一件事是您的数据可能为空,您是否尝试过检查列结构字段以查看它是否包含数据?
