Re: How to set queryset on the second step of a form wizard?
Override the process_step method do that when step one is being processed, it creates the queryset to be used by step 2 then. if(step==1): if(form.is_valid()): self.step2_queryset=Book.objects.filter(**form.cleaned_data) elif(step==0): self.step2_queryset=None Then, override the get_form method to grab the self.step2_queryset variable and use it in the form. Thus you don't have to worry about cleaning forms more than once. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: How to set queryset on the second step of a form wizard?
Don't worry. Form works now. Thanks a lot. But would be great if you can explain it a bit on how your code works and the sequence of how process_steps and get_form works as I see it seems called a few time between steps Thanks =) -r On Aug 21, 1:42 am, rr <[EMAIL PROTECTED]> wrote: > It works well.

Re: How to set queryset on the second step of a form wizard?
It works well. Thanks a lot. But now another problem. It seems "def done " is not working. It loops back to the step1 and def done is never called And do you mind explain how your code works? I did a "print step" before return form in the def get_from, it prints 0, 1, 0. It seems it has been called 3 times when submit in the second step What is the sequence of the call of process_step and get_form? the docs didn't explain much about this Thanks in Advance!! -r On Aug 20, 4:59 pm, Rajesh Dhawan <[EMAIL PROTECTED]> wrote: > On Aug 20, 12:57 pm, rr <[EMAIL PROTECTED]> wrote: > > > Thanks Rajesh > > > But...it doesn't work > > It complains about form0 doesn't have cleaned_data.

I just dpasted something that will help you capture the channelType from step 0 and then use it when the step 1 form is being created. http://dpaste.com/hold/72763/ If that doesn't work, please dpaste your MyFormWizard code. -Rajesh D --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: How to set queryset on the second step of a form wizard?
Thanks Rajesh But...it doesn't work It complains about form0 doesn't have cleaned_data. I guess form0 = super(MyFormWizard, self).get_form(0, data=data) only gives you a form with no data?!

So, as you found out, that's not going to work. Also, you are trying to set the queryset on form #1 when step is 0. That's not going to persist. > But it doesn't seems working... how can a dynamic choice can be > achieved depending on selection of previous step?! Try overriding the get_form method instead of process_step. Also, you will need to populate form #1's queryset when you are in step 1. So, the code would be something like this: def get_form(self, step, data=None): form = super(MyFormWizard, self).get_form(step, data=data) if step == 1: # Get step #0's form and set form #1's queryset based on it form0 = super(MyFormWizard, self).get_form(0, data=data) form.fields['channel'].queryset = form0.cleaned_data['channelType'].channel_set.all() return form -Rajesh D --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
