Question

I have problem using dict in python, I just end up with empty dictionary.

looks like I erase the data each itartion

this code suppose to generate a tests that include tests for each site.

thanks in advance

tests={}
for t in Test.objects.all():
    for s in Site.objects.all():
        site={}
        for sv in s.siteversions.all():
            siteversion=sv.version
            results=sv.results.filter(idTest=t)
            result=""
            if(results):
                result=results[0].result_test()
            site.update({sv.version:result})
        tests.update({t.name:site.copy()})
print tests

{u'load stuff': {u'X2': 'Success', u'X1': ''}}
{u'load stuff': {u'XP': 'Error'}}
{u'load stuff': {}}
{u'load stuff': {}, u'unload': {u'X2': 'Fail', u'X1': 'Error'}}
{u'load stuff': {}, u'unload': {u'XP': 'Success'}}
{u'load stuff': {}, u'unload': {}}

x2 and xp are versions

tests.update({t.name:site.copy()}) is executed for each site but with the same key: testname and somtimes you have sites witout test -> end up with empty dictionary.

to fix this you need a strcture like the following:

Test1 -> site1 -> test_results1
         site2 -> test_results2
         ...

Test2 -> site1 -> test_results1
         site2 -> test_results2
         ...

something like this:

tests={}
for t in Test.objects.all():
    sites={}
    for s in Site.objects.all():
        site_results={}
        for sv in s.siteversions.all():
            results=sv.results.filter(idTest=t)
            result = ''
            if(results):
                result=results[0].result_test()
            site_results[sv.version] = result
    sites[s.name] = site_results
tests[t.name] = sites

print tests
