Hi List, I am just starting to build an application using Django. And my first attempt outside of procedural PHP and Perl-CGI. I am already loving it so much (and ditched other two already).
I am trying to construct the following query at the end. Result.objects.filter(Q(analysis__experiment__experiment_code="PyLS24") |Q(analysis__experiment__experiment_code="PyLS40")) How I do now: The values are passed from a from(post) using checkboxes (#expcodes = request.POST.getlist('expcode') ). So I get a list of: expcodes = ['PyLS24', 'PyLS40'] then use the for loop to construct string representation of Q object. expcodes = ['PyLS24', 'PyLS40'] k='' c=0 for e in expcodes: j=e.join(['Q(analysis__experiment__experiment_code="','") ']) if c == 0: k = j else: k='|'.join([k, j]) c = c+1 k in this gives me 'Q(analysis__experiment__experiment_code="PyLS24") |Q(analysis__experiment__experiment_code="PyLS40") '. When i use this to query the model as following... Result.objects.filter(k)I get "ValueError: too many values to unpack" error. But, exact string, if I copy paste into Results.object.filter(here) it works. When I checked the type, k constructed from for loop is in string format (obviously). But, when I copy paste the pint out of k, it automatically becomes Django's Q object. Can anyone help me to sort this out. Or is there altogether a better way to do this query. I would really appreciate any help. Gowthaman -- You received this message because you are subscribed to the Google Groups "Django users" group.
