How to show joined table on the TSQLRibbonTabParameters

Hi,

I use TSQLRibbonTabParameters like in the MainDemo and I want to show some fields of the joined table instead of the ID.
I suppose that TSQLMemo has a property pointing joinedTable, is it possibile to do that :

(Table: TSQLMemo;
     Select: 'Name,Created,Modified,KeyWords,SignatureTime,joinedTable.Field1,joinedTable.Field2'; Group: GROUP_CLEAR; FieldWidth: 'IddIdII'; Actions: DEF_ACTIONS)

Thx,

Re: How to show joined table on the TSQLRibbonTabParameters

AFAIK this is not possible yet.

You have to embed the whole content in the TSQLRecord.

Re: How to show joined table on the TSQLRibbonTabParameters

Is there a way to detect the existance of a joined field in the TSQLRibbonTabParameters.Select property and then embed automaticaly the whole content ?
Why there's not a TSQLRibbonTabParameters.SQLWhere property to add a filter if needed ?

Thx,

Re: How to show joined table on the TSQLRibbonTabParameters

You can patch the mORMotTollbar code, for this purpose.
But this it not planned yet on our side.

Re: How to show joined table on the TSQLRibbonTabParameters

Hi AB,

I added two properties to TSQLRibbonTabParameters SQLWhere  and FieldAlign

unit mORMot;
....
  /// defines the settings for a Tab for User Interface generation
  // - used in mORMotToolBar.pas unit and TSQLModel.Create() overloaded method
  TSQLRibbonTabParameters = object
  public
    /// the Table associated to this Tab
    Table: TSQLRecordClass;
    /// the caption of the Tab, to be translated on the screen
    // - by default, Tab name is taken from TSQLRecord.Caption(nil) method
    // - but you can override this value by setting a pointer to a resourcestring
    CustomCaption: PResStringRec;
    /// the hint type of the Tab, to be translated on the screen
    // - by default, hint will replace all %s instance by the Tab name, as taken
    // from TSQLRecord.Caption(nil) method
    // - but you can override this value by setting a pointer to a resourcestring
    CustomHint: PResStringRec;
    /// SQL fields to be displayed on the data lists
    // 'ID,' is always added at the beginning
    Select: RawUTF8;
    /// SQL where to apply
    SQLWhere : RawUTF8;   <------------------------------
     /// Tab Group number (index starting at 0)
    Group: integer;
    /// displayed field length mean, one char per field (A=1,Z=26)
    // - put lowercase character in order to center the field data
    FieldWidth: RawUTF8; 
    /// displayed field align, one char par field (r=Right, l=Left, c=Center)
    FieldAlign: RawUTF8;   <------------------------------
....
unit mORMotToolBar;
......

end;

var L, i: integer;
    c: AnsiChar;
    Means: array of cardinal;
    a: AnsiChar;<---------------------------------------------
begin
  if self=nil then Exit;
  fMarkAllowed := aMarkAllowed;
  L := length(Lengths);
  if L=0 then begin
    SetLength(Means,Table.FieldCount);
    for i := 0 to Table.FieldCount-1 do
      Means[i] := 10; // some fixed width
  end else
  if Table.FieldCount=L then begin
    SetLength(Means,L);
    for i := 0 to L-1 do begin
      c := Lengths[i+1];
      if Aligns <> '' then                  <---------------------------------------------
      begin                                   <---------------------------------------------
        a := Aligns[i+1];                  <---------------------------------------------

          'c' :  Aligned[i] := alCenter; <---------------------------------------------
        end;                                  <---------------------------------------------
      end                                     <---------------------------------------------
      else                                     <---------------------------------------------
      if c in ['a'..'z'] then begin
        Aligned[i] := alCenter;
        dec(c,32);
      end;
      Means[i] := ord(c)+(-ord('A')+1);
    end;
    Table.SetFieldLengthMean(Means);
  end;
  if aMarkAllowed then
    Table.FieldLengthMeanIncrease(0,2); // space for Marked[] checkbox e.g.
end;

But for the joined table fields I'm blocked here:

unit mORMot;
......
function TSQLRestClientURI.List(const Tables: array of TSQLRecordClass;
  const SQLSelect, SQLWhere: RawUTF8): TSQLTableJSON;
var Resp, SQL: RawUTF8;
    U: RawUTF8;
    InternalState: cardinal;
    props: TSQLModelRecordProperties; <---------------------------------------------
begin
  result := nil;
  if high(Tables)<0 then exit;
  // GET Collection
  props := Model.Props[Tables[0]]; <---------------------------------------------
  SQL := props.SQL.SelectAllJoined; <---------------------------------------------
  if SQL = '' then                          <---------------------------------------------
    SQL := Model.SQLFromSelectWhere(Tables,SQLSelect,SQLWhere); <-------- SQLSelect='Name,Created,Modified,KeyWords,SignatureTime,joinedTable.Field1'
  if high(Tables)=0 then begin
    // one Table -> use REST protocol (SQL as parameters)
    if not IsRowID(pointer(SQLSelect)) then
      // ID selected by default
      U := '?select='+UrlEncode(SQLSelect) else
      U := '';
    if SQLWhere<>'' then begin
      if U<>'' then
        U := U+'&where=' else
        U := U+'?where=';
      U := U+UrlEncode(SQLWhere);
    end;
    with URI(Model.URI[TSQLRecordClass(Tables[0])]+U,'GET',@Resp) do <--- I got 'no such column : JoinedTable.Field1' because the URI accept only one table
      if Lo<>HTML_SUCCESS then
        exit else
        InternalState := Hi;
    result := TSQLTableJSON.CreateFromTables([Tables[0]],SQL,Resp); // get data
  end else begin
    // multiple tables -> send SQL statement as HTTP body
    with URI(Model.Root,'GET',@Resp,nil,@SQL) do
      if Lo<>HTML_SUCCESS then
        exit else
        InternalState := Hi;
    result := TSQLTableJSON.CreateFromTables(Tables,SQL,Resp); // get data
  end;
  result.fInternalState := InternalState;
end;
