Hi, I’ve got the following structures (or at least I’m hoping to be able to use them) ` list\_of\_files: - { filename: file1, version: 1 } - { filename: file2, version: 1 } - { filename: file3, version: 1 } - { filename: file1, version: 2 } - { filename: file2, version: 2 } - { filename: file1, version: 3 } - { filename: file1, version: 4 } - { filename: file1, version: 5 } - { filename: file2, version: 5 } dict\_name: key1: type: x dictversion: 1 key2: type: y dictversion: 2 key3: type: z dictversion: 1 ` I’d like to use **dict\_name.key.dictversion** to download all files from **list\_of\_files** where **dict\_name.keyX.dictversion==list\_of\_files.version.** Meaning, for each key, I’d like to get the (variable) number of files with the versionnumber that specific key has. I tried with this: ` - name: Get files get\_url: url={{ source }}/{{ item.0.filename }} dest={{ somewhere }} with\_together: - dict\_name - list\_of\_files when: “{{ dict\_name[item.1].dictversion }}” == "{{ item.0.version }} ` But it doesnt work. It errors out with a stacktrace: File “/usr/lib/python2.7/site-packages/ansible/runner/ **init**.py”, line 561, in \_executor exec\_rc = self.\_executor\_internal(host, new\_stdin) File “/usr/lib/python2.7/site-packages/ansible/runner/ **init**.py”, line 696, in \_executor\_internal complex\_args=complex\_args File “/usr/lib/python2.7/site-packages/ansible/runner/ **init**.py”, line 756, in \_executor\_internal\_inner if not utils.check\_conditional(cond, self.basedir, inject, fail\_on\_undefined=self.error\_on\_undefined\_vars): File “/usr/lib/python2.7/site-packages/ansible/utils/ **init**.py”, line 254, in check\_conditional conditional = template.template(basedir, conditional, inject, fail\_on\_undefined=fail\_on\_undefined) File “/usr/lib/python2.7/site-packages/ansible/utils/template.py”, line 115, in template varname = template\_from\_string(basedir, varname, vars, fail\_on\_undefined) File “/usr/lib/python2.7/site-packages/ansible/utils/template.py”, line 357, in template\_from\_string res = jinja2.utils.concat(rf) File “”, line 10, in root File “/usr/lib/python2.7/site-packages/jinja2/environment.py”, line 372, in getattr return getattr(obj, attribute) File “/usr/lib/python2.7/site-packages/jinja2/runtime.py”, line 463, in **getattr** return self.\_fail\_with\_undefined\_error() File “/usr/lib/python2.7/site-packages/jinja2/runtime.py”, line 457, in \_fail\_with\_undefined\_error raise self.\_undefined\_exception(hint) UndefinedError: dict object has no element None Is this even possible? I could work around this by adding something like a ‘download: true/false’ to the list and use that in the when:, but I really like the to be able to control which files to get by using the dictversion variable in **dict\_name** regards /Micke ---

Ok, haven’t seen that before and I’m starting to think I’m getting out of my depth here, so efter a lot of trial I managed this: ` ---

So I havent made any progress with this, and given the lack of response I take it this will not work? The workaround hack it is then /Micke ---

Yeah, fair enough 😉 It would be interesting to know though if this isn’t working because: 1. It should/could work but I’m not doing it right 2. It doesnt/will not work and I should just stop trying Either way, the stacktrace is kinda ugly?
