What GitHub issue does this PR apply to?

Resolves #635

What changed and why?

• New command generate_missing_templates which generates all missing thesaurus.

  python manage.py generate_missing_templates

• New function in the Language model named is_incomplete.

  def is_incomplete(self, version, structure_key):
     """
     Returns a Boolean if the version is incomplete
  
     :param version: the version of the language
     :param structure_key: the ID for the structure to load
     :return: Boolean if the version is incomplete
     """
  
     template = self.load_filled_concepts(structure_key, version)
     template = json.loads(template)
     
     for concept in template["concepts"].values():
         code = concept.get("code")
         not_implemented = concept.get("not-implemented", None)
         comment = concept.get("comment", None)
         if isinstance(code, list):
             code = "".join(code)
         if isinstance(code, str) and code.strip() == "" and not_implemented is None and comment is None:
             return True
  
     return False

Any additional comments or things to be aware of while reviewing?

[ulyssear]

I'm working on unit tests, but I have no idea how I could add draft mode inside the tests.
Would it be possible to have a track of what I could put?

So besides the two comments, when I go to the review app, I don't see the UI addition. Shouldn't I see it here?

[geekygirlsarah]

Should this get removed as I think we decided against "draft mode"?

[ulyssear]

I forgot to remove it, sorry for that.

[geekygirlsarah]

Same for removing this

OK, I know what's happened: the method "is_incomplete" checks if the code fields are empty in the template inside the thesaurus folder. But in the case of some files, these entries (with "Unknown") are not present and thus, no condition is done there (so, the result will be False, instead of True).
We have to check with the complete template but I don't know if it's a good practice, I will even so put this solution.

I'm going to go ahead and close this because there's some merge conflicts and I haven't seen activity since November.

If you want to keep working on it, you're welcome to! You can reopen this or make a new pull request to keep working on it.

Thanks for the work you've put into it so far!

[ulyssear]

I'll check on my side to fix the merge conflicts !
I may do this this week, or next week at the latest.
