Problem understaning nesting for loops in ODS tempalte

I did this, it's very easy.

Just nest lists and make Data Holders (an empty class) or Dictionaries so you can store the data in them. In python is like this:

class DataHolder():
    pass

Then you can add data in it and then pass it to the render. This is an example on the fly:

listX = []
for x in range(10): #Or whatever your cycle is
    groupX = DataHolder()
    groupX.id = x
    groupX.name = 'SomeData'
    listX.append(groupX)

for i in listX:
    groupY = DataHolder()
    groupY.detail = 'More data Data'
    groupY.detailList = ['orange','banana','lemons','etc']
    i.groupY = groupY

At this point you have a list of nested items in listX. This is the list you send to the render and in the appy you need to make a loop. Insert a table and in one row insert a comment. Then type something like this (for this example):

do row for x in listX

And you can print the info in the cells by typing "x.id", "x.name" and "x.groupY.detail" in them with "change control on".

For printing the detail you must insert another table inside one cell and then make another loop. In the firts row add a comment and type something like this:

do row for y in x.groupY.detailList:

This will make a table inside a cell and print in them 'orange','banana','lemons','etc' one of them in each row.

I hope this helped you and sorry for my english, is not my native language.

Regards.
