[Zope] Solution: how to pass variables into ZGDChart

[Jaroslav Lukesh]

Hi all,

 

I was find simple solution how to pass variables into DTML method of
ZGDChart product. It was discussed few years ago via SESSION - see
http://mail.zope.org/pipermail/zope/2003-April/135196.html

Note, that for my old Zope 2.5.1 is functional version
ZGDChart-0.6.4babel.tgz only

 

So here are DTML document from where we calling image:

 

<dtml-if users_id>

<dtml-elif user_id>

    <dtml-call "REQUEST.set('users_id', [])">

    <dtml-call "users_id.append(user_id)">

<dtml-else>

    <dtml-call "REQUEST.set('users_id', [0])">

</dtml-if>

 

<dtml-call "REQUEST.set('temp_labels', [])">

<dtml-call "REQUEST.set('temp_data1',  [])">

<dtml-call "REQUEST.set('temp_data2',  [])">

 

<dtml-in ZSQL_query>

    <dtml-call "temp_labels.append(month + ' ' + year)">

    <dtml-call "temp_data1.append((time1 or 0.00000) / _.len(users_id) ))">

    <dtml-call "temp_data2.append((time2 or 0.00000) / _.len(users_id) ))">

</dtml-in>

 

<img src="ZGDChart_graph/?data0=<dtml-var "_.string.join(temp_labels, ',')
">&data1=<dtml-var "_.string.join(temp_data1, ',') ">&data2=<dtml-var
"_.string.join(temp_data2, ',') ">">

 

-----------

 

And here are DTML method from inside of ZDGChart_graph:

 

<dtml-call "REQUEST.set('temp_labels', _.string.split(data0, ',' ) )">

<dtml-call "REQUEST.set('x_data1',  _.string.split(data1, ',' ) )">

<dtml-call "REQUEST.set('x_data2',  _.string.split(data2, ',' ) )">

 

<dtml-call "REQUEST.set('temp_data1',  [] )">

<dtml-call "REQUEST.set('temp_data2',  [] )">

 

<dtml-in x_data1 prefix=cislo>

    <dtml-call "temp_data1.append(_.float(cislo_item))">

</dtml-in>

 

<dtml-in x_data2 prefix=cislo>

    <dtml-call "temp_data2.append(_.float(cislo_item))">

</dtml-in>

 

<dtml-return "(temp_labels, temp_data1, temp_data2)">

 

 

 

Happy using!

 

Regards, JL.
