Question

我将我的事务添加到字典中,使用UUID作为键,将事务对象作为值 - 这就是我所说的ledger:

实施例(entriesForPosting是一个Set的ArrayS,各自含有信用条目和借记):

   postToGL
    entriesForPosting do: [ :ea | GeneralLedger ledger at: (ea at: 1) mUID put: (ea at: 1).  "credit"
                                  GeneralLedger ledger at:(ea at: 2) mUID put: (ea at: 2) ].  "debit"

然后我们报告这个分类帐:

renderReport
    GLReport := WATableReport new
        rows: GeneralLedger getGLPostings asOrderedCollection ;
        columns: (OrderedCollection new
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: each  ]
                title: 'ID');
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: (GeneralLedger getTransactionByID: each) mDate ]
                title: 'Transaction Date');
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: (GeneralLedger getTransactionByID: each) mAmount ]
                title: 'Amount');
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: ((GeneralLedger getTransactionByID: each) mGLAC mAccountCode)]
                title: 'GLAC');
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: ((GeneralLedger getTransactionByID: each) mFund mFundCode)]
                title: 'Fund');
            yourself);
        rowColors: #(lightblue lightyellow);
        rowPeriod: 1;
        yourself. 

我遇到的问题是,这个报告没有订购.即,交易显示无序 - 我没有看到任何押韵或理由为什么他们被报告如何:

例如,

spndMgr buildTransactionFor: 100 against: someGLAC.
spndMgr buildTransactionFor: 110 against: someGLAC.
spndMgr buildTransactionFor: 120 against: someGLAC.
spndMgr buildTransactionFor: 130 against: someGLAC.
spndMgr buildTransactionFor: 140 against: someGLAC.
spndMgr buildTransactionFor: 150 against: someGLAC.
spndMgr buildTransactionFor: 160 against: someGLAC.
spndMgr buildTransactionFor: 170 against: someGLAC.
spndMgr buildTransactionFor: 180 against: someGLAC.
spndMgr buildTransactionFor: 190 against: someGLAC.
spndMgr buildTransactionFor: 200 against: someGLAC.
spndMgr postTransactions.

给我以下内容:

我尝试过以下方法:

renderReport
    |columnToSortBy|

    GLReport := WATableReport new
        rows: GeneralLedger getGLPostings asOrderedCollection ;
        columns: (OrderedCollection new
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: (GeneralLedger getTransactionByID: each)  mIdentity ]
                title: 'Identity');
            add: (columnToSortBy := (WAReportColumn
                renderBlock: [ :each :html | html emphasis: (GeneralLedger getTransactionByID: each) mDate ]
                title: 'Transaction Date') );               
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: (GeneralLedger getTransactionByID: each) mAmount ]
                title: 'Amount');
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: ((GeneralLedger getTransactionByID: each) mGLAC mAccountCode)]
                title: 'GLAC');
            add: (WAReportColumn
                renderBlock: [ :each :html | html emphasis: ((GeneralLedger getTransactionByID: each) mFund mFundCode)]
                title: 'Fund');
            yourself);
        rowColors: #(lightblue lightyellow);
        rowPeriod: 1;
        sortColumn: columnToSortBy;
        yourself. 

但这会在渲染时抛出错误:

Answer 1

1. WAReportColumn理解#sortBlock:.该块初始化为[ :a :b | a <= b ]a和b将是glPosting我假设的一些对象.如果此排序行为不适合您,只需将不同的排序块传递给该列.

2. WAReportTable理解#sortColumn:.默认情况下,传递您想要排序的列,如下所示:

   ...
   add: (columnToSortBy := (WAReportColumn
       renderBlock: [ :each :html | html emphasis: (GeneralLedger getTransactionByID: each) mAmount ]
       title: 'Amount';
       yourself));
   ...
   rowColors: #(lightblue lightyellow);
   rowPeriod: 1;
   sortColumn: columnToSortBy;
   yourself.
