Jinja2 {% include file %} outside of search path doesn't work

问题

This is an elementary issue which is probably related to Jinja2 PrefixLoader or ChoiceLoader.

On Python 3.6 we load with this command

jinja2.FileSystemLoader( searchpath= "\\template_folder\\")

On Windows 7, our file structure is as follows.

- folder_bbb
    * subfile.txt
- template_folder
     * template_file
     - folder_aaa
         * subfile.txt

From the template_file we are successful with this command

{% include "folder_aaa/subfile.txt" %} 

Now we wish to move the file one level up, and write

{% include "../folder_bbb/subfile.txt" %}

but that doesn't work, complaining file not found.

What is the correct way to write? Thanks.

回答1:

You may specify all paths in the the loader

jinja2.FileSystemLoader(["c:\\template_folder\\", "c:\\folder_bbb\\"])

and refer the including block without a specific path

{% include "subfile.txt" %} 

The path will be searched in order so that as you say, moving the file one level up, the file will be found. (You need the template_folder path for the template itself.)
