Re: Django template iterating through two dictionaries/variables

Thanks Asad. Is that why I'm getting errors saying invalid filter name?

Also I'm having a difficult time thinking my way through the workflow. I'm defining a new function that requires scores(my URL based dictionary) and person (my database dictionary). The function then asks to return the scores of the corresponding game number. Then the template is looking for the correct value in the scores dictionary that has the same Number identification as the existing person.Number?

I think what is confusing me is the use of "player" in ludovics example

Thanks

Aaron

No need to change the context, since the variable names the example here uses are the same as your existing context. It should work as long as you remember to {% load APPNAME %} your filters in the template first.

Thanks ludovic,

I'm trying to write that python code presently- would I have to also change the context?  how would that look?

Thanks

You could write a filter [1]. It would be used like {{
scores|from_player:person }} and look like that:

    def from_player (scores, player):
        return scores[player.Number]

You might want to adjust to your actual code, check that you got the
right arguments and that kind of things.
