CookieWizardView / SessionWizardView + extra fields + dynamic steps + formset and/or inlineformset?

[Fabio Caritas Barrionuevo da Luz]

Hello everyone

 

Does anyone have any idea or any example to create a CookieWizard that the first step has some extra fields and the next steps based on the same extra fields, are created or updated automatically steps with formset or inlineformset?

I am a relatively new django User.

My current challenge:

I have the following class models to my Gas station manager django app:

models:

I need to create a WizzardView Gas Station(Posto), and create related models , and some models related models related to Gas Station(Posto) .

In the initial step , the User shall inform the name of the Gas Station(Posto) and the number of pumps(Bomba) and tanks(Tanque) of Gas Station(Posto).

In the second step , based on number of pumps(Bomba) and tanks(Tanque) set in an initial step, the amount of displayed forms pumps(Bomba) and tanks(Tanque).

For each pump(Bomba), the User should inline insert nozzle(Bico).

I found a project to nested inlines formset. I made a fork and applied modifications, but still not good.

for me , the ideal solution would be that the django have its " simple " to do so , within and outside the django admin .

Maybe something like described in issue 9025 and comment of the silverfix
