I have to build an app that has many (~15) interdependent selection fields that come from large datasets across multiple different types of databases.
For example, field A might have 10 values in a drop down, and when the user selects "FOO", then field B's drop down gets populated with 30 choices only applicable to "FOO". Then a selection in B of "BAR" causes drop down C to get populated with 100 choices only applicable to FOO/BAR. And so on. The 2 ways I can think of to do this are: 1) each time a field is chosen send an ajax request to get the values for the dependent fields or 2) pull all the data when the page is initially rendered and do it all on the browser without going back to the server Obviously, the first will cause a lot of delay each time a field is chosen, whereas the second will cause a big delay to first load the page, but then it would be responsive after that. What I am wondering is, are there any other strategies for a problem like this? How have people here dealt with a situation like this? -- You received this message because you are subscribed to the Google Groups "Django users" group.
