Need support for nested data in get_undeclared_template_variables method

[roynrishingha]

Feature Details

In a .docx file, if a variable defined as {{ foo }} , the get_undeclared_template_variables method returns me foo which is what I expect. But if the variable is defined as {{ foo.bar }}, it still returns only foo. It does not recursively look for nested variables.

In the method implementation, I noticed that, first jinja AST is built and passed to find_undeclared_variables of the meta module of jinja2. I don't get it why the AST does not help us getting the nested variables.

Solution

I do not have any idea of how this can be solved. Therefore I'm opening this issue in a hope that someone from community will help me out.

I think I have a (Maybe) Related Issue, although with a different Outcome.

If I have {{ foo }} in the template, then the get_undeclared_template_variables method returns nothing if foo is defined.

However, if I have {{ foo["Bar"] }} in the template, then the get_undeclared_template_variables method returns foo, even though foo["Bar"] is defined and the Template renders correctly (and replaces those Occurrences with the required Values).

Although maybe the Usual Python Dict way of accessing elements foor["Bar"] is NOT correct in Microsoft Word / Libreoffice (since both Single Quotes and Double Quotes are "weird", i.e. NOT the "normal" Single or Double quotes you would use in Python, BASH Scripts, etc).
