ColdFusion-Struktur verschachtelte Elemente?

Question

Ich möchte verschachtelte Elemente innerhalb der Struktur festlegen. Hier ist ein Beispiel meines aktuellen Codes:

<cfset fnResults = StructNew()> 
<cfset dateList = "HD_DATE1,HD_DATE2,HD_DATE3,HD_DATE4" /> 
<cfset servicesEquipment = { 
    1="Strongly Agree", 
    2="Agree", 
    3="Don't Know", 
    4="Disagree", 
    5="Strongly Disagree" 
}> 
<cfset isActive = { 
    1="Yes ", 
    0="No " 
}> 

<cfquery name="UserInfo" datasource="TestDB"> 
    SELECT TOP 1 
     hd_yn1, 
     hd_active, 
     hd_date1, 
     hd_status, 
     hd_age1, 
     hd_date2, 
     hd_age2, 
     hd_date3, 
     hd_date4, 
     hd_age3, 
     hd_deg1, 
     hd_deg2, 
     hd_toner, 
     hd_cfgr, 
     hd_deg4, 
     hd_deg5, 
     hd_tonel, 
     hd_cfgl, 
     hd_hri, 
     hd_comment, 
     hd_rear, 
     hd_lear, 
     hd_tosound, 
     LTRIM(RTRIM(si_last)) + ', ' + LTRIM(RTRIM(si_first)) AS hd_staff, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_YN1' AND tm_code = hd_yn1) AS zhd_yn1, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_STATUS' AND tm_code = hd_status) AS zhd_status, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_AGE' AND tm_code = hd_age1) AS zhd_age1, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_AGE' AND tm_code = hd_age2) AS zhd_age2, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_AGE' AND tm_code = hd_age3) AS zhd_age3, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HEAR_IND' AND tm_code = hd_hri) AS zhd_hri, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HEAR_LOSS' AND tm_code = hd_deg1) AS zhd_deg1, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HEAR_LOSS' AND tm_code = hd_deg4) AS zhd_deg4, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HEAR_TYPE' AND tm_code = hd_deg2) AS zhd_deg2, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HEAR_TYPE' AND tm_code = hd_deg5) AS zhd_deg5, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_TONE' AND tm_code = hd_toner) AS zhd_toner, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_TONE' AND tm_code = hd_tonel) AS zhd_tonel, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_CFG' AND tm_code = hd_cfgr) AS zhd_cfgr, 
     (SELECT TOP 1 tm_name FROM hmMaster WHERE tm_tblid = 'HD_CFG' AND tm_code = hd_cfgl) AS zhd_cfgl 
    FROM userRec WITH (NOLOCK) 
     LEFT OUTER JOIN staffInfo 
      ON si_staff = hd_staff 
    WHERE hd_userid = '10051989' 
</cfquery> 

<cfset fnResults.recordcount = UserInfo.recordcount> 

<cfif UserInfo.recordcount EQ 0> 
    <cfset fnResults.message = "No records were found."> 
<cfelse> 
    <cfloop query="UserInfo"> 
     <cfset qryRecs = StructNew()> 
     <cfloop array="#UserInfo.getColumnList()#" index="columnName"> 
      <cfif listContains(dateList, columnName, ",")> 
       <cfset qryRecs[columnName] = URLEncodedFormat(Trim(DateFormat(UserInfo[columnName][CurrentRow],'mm/dd/yyyy')))> 
      <cfelseif columnName EQ 'hd_active'> 
       <cfset qryRecs[columnName] = URLEncodedFormat((structKeyExists(isActive, LossInfo[columnName][CurrentRow]))? isActive[UserInfo[columnName][CurrentRow]]:"No ")> 
      <cfelseif columnName EQ 'hd_tosound'> 
       <cfset qryRecs[columnName] = URLEncodedFormat((structKeyExists(servicesEquipment, UserInfo[columnName][CurrentRow]))? servicesEquipment[UserInfo[columnName][CurrentRow]]:"")> 
      <cfelse> 
       <cfset qryRecs[columnName] = URLEncodedFormat(Trim(UserInfo[columnName][CurrentRow]))> 
      </cfif> 
     </cfloop> 
    </cfloop> 

    <cfset fnResults.data = qryRecs> 
</cfif> 

<cfdump var="#fnResults#"> 

Code oben verwenden Sie einige Logik, um die Daten zu manipulieren. Hier ist Beispiel für meine Ausgabe, nachdem ich fncResults Dump:

DATA  
struct 
HD_ACTIVE No%20 
HD_AGE1  [empty string] 
HD_AGE2  [empty string] 
HD_AGE3  36 
HD_CFGL  MMO 
HD_CFGR  MMO 
HD_COMMENT Test 
HD_DATE1 09%2F22%2F1993 
HD_DATE2 [empty string] 
HD_DATE3 [empty string] 
HD_DATE4 [empty string] 
HD_DEG1  II 
HD_DEG2  MM 
HD_DEG4  MM 
HD_DEG5  UU 
HD_HRI NN 
HD_LEAR  [empty string] 
HD_REAR  [empty string] 
HD_STAFF [empty string] 
HD_STATUS PESS 
HD_TONEL ALL 
HD_TONER ALL 
HD_TOSOUND [empty string] 
HD_YN1 Y 
ZHD_AGE1 [empty string] 
ZHD_AGE2 [empty string] 
ZHD_AGE3 36 
ZHD_CFGL MIDDLE 
ZHD_CFGR Mild 
ZHD_DEG1 Mild 
ZHD_DEG2 Unknown 
ZHD_DEG4 Mild 
ZHD_DEG5 Unknown 
ZHD_HRI  None 
ZHD_STATUS Maybe 
ZHD_TONEL All 
ZHD_TONER All 
ZHD_YN1  Did Not 
RECORDCOUNT  1 

Am vorderen Ende ich alle Felder festgelegt haben, die Buchstaben ‚z‘ vor ‚hs‘ haben, um meine Daten für den Titel-Attribut zu sein. Aus diesem Grund möchte ich meine Struktur organisieren, wie folgt aussehen:

DATA  
    struct 
    HD_ACTIVE Value: No%20 Title: This is test 
    HD_AGE3  Value: 36 Title: Years 
    HD_COMMENT Value: Test Title: Test 

Als Randbemerkung Ich habe versucht, verschachtelte Variablen in meiner Struktur zu setzen. Etwas wie folgt aus: <cfset qryRecs[columnName].value =UserInfo[columnName][CurrentRow]> Diese werfen einen Fehler:

Element HD_YN1 is undefined in a CFML structure referenced as part of an expression. 

Ich bin nicht sicher, ob ich brauche noch eine Struktur, um das achive. Auch bin ich nicht sicher, was der beste Weg ist, um diese Art von Struktur zu organisieren. Wenn Sie Vorschläge oder Beispiele haben, lassen Sie es mich bitte wissen. Vielen Dank!

Answer 1

Dieses Code-Snippet ist keine vollständige Antwort, sondern sollte Ihnen bei der Verschachtelung von Strukturen mit den Value/Title-Schlüsseln helfen.

<!--- in order to nest structs, the 'nesting' parent structs must be created before assigning values to them ---> 
<cfif NOT structKeyExists(qryRecs, "columnName")> 
    <cfset qryRecs[columnName] = structNew()> 
</cfif> 
<!--- qryRecs[columnName] now exists as a struct so 'Value', 'Title', etc. keys can be added to it ---> 
<cfset qryRecs[columnName].value = UserInfo[columnName][CurrentRow]>
