説明

I have the following structure, passed to Selmer as variable 'res':

[ { :a "A1"
    :b "B1"
     :c [{ :aa "AA1"
            :bb "BB1"
            :cc "CC1"}
          { :aa "AA2"
            :bb "BB2"
            :cc "CC2"}
          { :aa "AA3"
            :bb "BB3"
             :cc "CC3"}]}
    {:a "A2"
     :b "B2"
      :c [{ :aa "AA11"
             :bb "BB11"
             :cc "CC11"}
           { :aa "AA21"
             :bb "BB21"
             :cc "CC21"}
          { :aa "AA31"
            :bb "BB31"
             :cc "CC31"}]}]

I want to iterate over the items in the first vector and print them out, and when getting to the ':c' fields I want to then start an inner iteration to print out the contents.

At the moment it is possible to get to every element in the structure with dotted notation. However, when I introduce an iterator using {% for n in res %} I then can not repeat this for the inner vector. Is this a lacking feature or am I not seeing the bigger picture? Thanks

前提条件: Clojure basicsSelmer template syntaxUnderstanding of for loop contextRecursion patterns
初心者向け度: 30
調査方針: Investigate the current implementation of the {% for %} tag in Selmer, likely in the template parsing files such as src/selmer/parser.clj. Look at how the for loop context is created and how nested loops are handled. Check if there is any recursion support or if the context is flattened. Consider adding support for nested loops by properly managing the loop variables and scopes. Review any existing tests for for loops to understand expected behavior.
