填充字段值作爲數據列查看MVC

Question

我有以下2個表：

此表包含列：

此表包含與這些列中的值：

我想在這種格式在我看來：

伊夫放入其中，我通過我的模型傳遞給視圖一個IEnumerable：

public class BudgetEntryNotesVM 
{ 
    public string AccountNumber { get; set; } 
    public string AccountDescription { get; set; } 
    public IEnumerable<BudgetNoteLineEntryVM> BudgetNoteLineEntryList { get; set; } 

} 

public class BudgetNoteLineEntryVM 
{ 
    public int pkiNotesLineEntriesId { get; set; } 
    public int fkiAccountId { get; set; } 
    public string NotesColumnName { get; set; } 
    public string Value { get; set; } 
    public bool isNewLineItem { get; set; } 
    public int Sequence { get; set; } 
} 

我使用下面的填充數據：

public IEnumerable<BudgetNoteLineEntryVM> GetBudgetNoteLineEntry(int accId) 
    { 
     IEnumerable<BudgetNoteLineEntryVM> AccountsLineEntriesIList = new List<BudgetNoteLineEntryVM>(); 

     //var query2 =(from) 

     var query = (from NC in _context.Notes_Columns 
        join NLE in _context.Notes_Line_Entries on NC.pkiNotesColumnsId equals NLE.fkiNotesColumnId 
        where NLE.fkiAccountId == accId 
        select new BudgetNoteLineEntryVM 
        { 
         pkiNotesLineEntriesId = NLE.pkiNotesLineEntriesId, 
         fkiAccountId = NLE.fkiAccountId, 
         NotesColumnName = NC.NotesColumnName, 
         Value = NLE.Value, 
         isNewLineItem = NLE.isNewEntry, 
         Sequence = NC.Sequence 

        }).Distinct().OrderBy(n => n.Sequence); 

     AccountsLineEntriesIList = query; 

     return AccountsLineEntriesIList; 
    } 

和IM填充它和傳球它是這樣的：

public ActionResult BudgetNoteLineEntry(int accId) 
    { 
     BudgetEntryNotesVM NVM = new BudgetEntryNotesVM(); 

     NVM.AccountNumber = _budgetEntryRepository.GetAccountName(accId); 
     NVM.AccountDescription = _budgetEntryRepository.GetAccountDescription(accId); 

     NVM.BudgetNoteLineEntryList = _budgetEntryRepository.GetBudgetNoteLineEntry(accId); 

     return PartialView("_ShowAccountBudgetLineEntries", NVM); 
    } 

我根本無法想到了解決辦法，我希望有人可能會導致我在正確的方向。

謝謝。

Answer 1

如果你有8個條目的序列，沒有跳過的數字，你可以做這樣的事情

你的數據實體可能看起來像

public class TableEntry 
{ 
    public int pkiNotesLineEntriesId { get; set; } 
    public int fkiAccountId { get; set; } 
    public int fkiNotesColumnId { get; set; } 
    public string Value { get; set; } 
    public bool isNewEntry { get; set; } 
} 

所以，你可以把你的表數據成一個列表陣列：

List<TableEntry[]> desiredFormat = new List<TableEntry[]>(); 

int pages = entries.Count()/8; 
for (int page = 0; page < pages; page++) 
{ 
    TableEntry[] row = entries.OrderBy(e => e.pkiNotesLineEntriesId).Skip(page * 8).Take(8).ToArray(); 
    desiredFormat.Add(row); 
} 

然後，它與頭的數組傳遞到您的視圖，並分別使它們到一個表中。

如果沒有一定的規模，你可以使用這個

int maxSize = entries.Max(c => c.fkiNotesColumnId); 
TableEntry[] row = new TableEntry[maxSize]; 
int current = 0; 
foreach (var entry in entries) 
{ 
    if (entry.fkiNotesColumnId < current) 
    { 
     desiredFormat.Add(row); 
     row = new TableEntry[maxSize]; 
     current = 0; 
    } 
    row[entry.fkiNotesColumnId - 1] = entry; 
    current = entry.fkiNotesColumnId; 
} 

Answer 2

感謝來自安德烈的幫助下，我利用二維數組。我的方式做到了也許不是最好的出路在那裏，但它的工作：

視圖模型：在我的倉庫

public class BudgetEntryNotesVM 
{ 
    public string AccountNumber { get; set; } 
    public string AccountDescription { get; set; } 
    public IEnumerable<BudgetNoteLineEntryVM> BudgetNoteLineEntryList { get; set; } 
    public IEnumerable<BudgetNoteLineEntryColumnsVM> BudgetNoteLineEntryColumnsList { get; set; } 
    public string[,] BudgetLineEntryArray { get; set; } 
} 

功能（同包含我的所有函數的類）：

//Getting Columns to populate table in PartialView 
    public IEnumerable<BudgetNoteLineEntryColumnsVM> GetBudgetNoteEntryLineColumns(int accId) 
    { 
     IEnumerable<BudgetNoteLineEntryColumnsVM> AccountsLineEntriesColumnIList = new List<BudgetNoteLineEntryColumnsVM>(); 

     //var query2 =(from) 

     var query = (from NC in _context.Notes_Columns 
        join NLE in _context.Notes_Line_Entries on NC.pkiNotesColumnsId equals NLE.fkiNotesColumnId 
        where NLE.fkiAccountId == accId 
        select new BudgetNoteLineEntryColumnsVM 
        { 
         Sequence = NC.Sequence, 
         ColumnName = NC.NotesColumnName 

        }).Distinct().OrderBy(n=>n.Sequence); 

     AccountsLineEntriesColumnIList = query; 

     return AccountsLineEntriesColumnIList; 
    } 

//Getting data to populate table 
    public string[,] GetBudgetNoteLineEntry(int accId) 
    { 
     int row = 0; 
     int column = 0; 

     //Getting total number of rows based on the EntryLineId 
     var outer = (from NC in _context.Notes_Columns 
        join NLE in _context.Notes_Line_Entries on NC.pkiNotesColumnsId equals NLE.fkiNotesColumnId 
        where NLE.fkiAccountId == accId 
        select NLE.EntryLineId).Distinct().Count(); 

     //Getting total number of columns based on the Account ID 
     var inner = (from NC in _context.Notes_Columns 
        join NLE in _context.Notes_Line_Entries on NC.pkiNotesColumnsId equals NLE.fkiNotesColumnId 
        where NLE.fkiAccountId == accId 
        select NC.NotesColumnName).Distinct().Count(); 

     //Declaring 2D Array with Inner and Outer values above 
     string[,] entrylines = new string[outer, inner]; 

     //Getting all data in order of the Columns 
     var query = (from NC in _context.Notes_Columns 
        join NLE in _context.Notes_Line_Entries on NC.pkiNotesColumnsId equals NLE.fkiNotesColumnId 
        where NLE.fkiAccountId == accId 
        select new BudgetNoteLineEntryVM 
        { 
         pkiNotesLineEntriesId = NLE.pkiNotesLineEntriesId, 
         fkiAccountId = NLE.fkiAccountId, 
         NotesColumnName = NC.NotesColumnName, 
         Value = NLE.Value, 
         isNewLineItem = NLE.isNewEntry, 
         Sequence = NC.Sequence, 
         EntryLineId = NLE.EntryLineId 

        }).Distinct().OrderBy(n => n.Sequence).ThenBy(n=>n.EntryLineId); 

     //Looping through every item and adding to 2D array based on the ordering of the columns 
     foreach(var item in query) 
     { 
      if(row >= outer) 
      { 
       row = 0; 
       column++; 
      } 

      entrylines[row, column] = item.Value; 

      if (row <= outer) 
      { 
       row++; 
      } 

     } 

     return entrylines; 
    } 

控制器

public ActionResult BudgetNoteLineEntry(int accId) 
    { 
     BudgetEntryNotesVM NVM = new BudgetEntryNotesVM(); 

     NVM.AccountNumber = _budgetEntryRepository.GetAccountName(accId); 
     NVM.AccountDescription = _budgetEntryRepository.GetAccountDescription(accId); 

     NVM.BudgetNoteLineEntryColumnsList = _budgetEntryRepository.GetBudgetNoteEntryLineColumns(accId); 
     //NVM.BudgetNoteLineEntryList = _budgetEntryRepository.GetBudgetNoteLineEntry(accId); 
     NVM.BudgetLineEntryArray = _budgetEntryRepository.GetBudgetNoteLineEntry(accId); 

     return PartialView("_ShowAccountBudgetLineEntries", NVM); 
    } 

筆者認爲：

@model BudgetEntryNotesVM 

<div id="listofBudgetEntries"> 
<div class="row"> 
    <div class="col-lg-12"> 
     <div class="panel panel-default"> 
      <div class="panel-heading clearfix"> 
       <h3 class="panel-title">Note Line Entries</h3> 
      </div> 

      <div class="panel-body"> 
       <div class="table-responsive"> 
        <table class="table table-condensed table-bordered table-hover"> 
         <tr style="background-color: #00b8ce; color: white;"> 
          @foreach (var hlitem in Model.BudgetNoteLineEntryColumnsList) 
          { 
           <th> 
            @Html.DisplayFor(modelhitem => hlitem.ColumnName) 
           </th> 


          } 
         </tr> 

         @for (int row = 0; row <= Model.BudgetLineEntryArray.GetUpperBound(0); row++) 
         { 
          <tr> 
           @for (int column = 0; column <= Model.BudgetLineEntryArray.GetUpperBound(1); column++) 
           { 
            <td>@Model.BudgetLineEntryArray[row, column]</td> 
           } 
          </tr> 
         } 
        </table> 
       </div> 
      </div> 
     </div> 
    </div> 
</div> 

我知道這是很習慣我需要什麼，但也許這可以幫助別人有想法，如果他們正在尋找在做同樣的事情。我仍然認爲有這樣做的更好的方法，但是爲了找到更好的解決方案，我一直苦苦掙扎。

安德烈，再次感謝您帶領我走向正確的方向。
