Question about asking questions and generation in a loop

[amitjindal]

Hi, I want to understand how I would attempt to do the following. I tried to find answers in documentation, and other reference implementations and even tests. But they don't all seem to add up.

Here's what I want to do

I want to generate source code for all the models in a django application along with their templates, views and other files. If you are not familiar with django, that's okay. I will explain.
So given I have 2 models, I want to ask questions related to each model and then generate code. The models can also be 3/5 or any number.

For example, if I have first and second as models, I would expect to get:

1. forms.py (contains definitions for both first and second form).
2. templates/first.html
3. templates/second.html

In essence, I need to loop inside the file as well as on the directory itself.

Here's how I thought I would approach this

I wanted to write the model structure in a JSON or YML (list of models and their associated properties.

project_name:
  type: str
  help: Your project name

author_username:
  type: str
  help: Your username (e.g. on GitHub)

models:
  - first:
      type: str
      help: First model name
  - second:
      type: str
      help: Second model name

When I run this the output is:

author_username? Format: str
🎤 [None]: dsf

models? Format: yaml
🎤 [[{'first': {'type': 'str', 'help': 'First model name'}}, {'second': {'type': 'str', 'help': 'Second model name'}}]]: 

    create  README.md
    create  .copier-answers.yml
    create  Makefile

I wanted copier to recurse and ask questions about first and second.

Other possibilities

Invoking multiple times

As an alternative I am thinking about writing a python program where I would read the models data from a JSON or YML and merge that with questions somehow to get the desired outcome. Maybe even run the copy command multiple times with each model.

So I want to know:

1. Is there a way to do this?
2. How can I invoke the copy command with additional data that would start asking questions?
3. Will it append to answers?
4. Will it append to generated files?

Asking questions in a loop

Second alternative may be to ask questions in a loop, collect answers and then pass them to copy command as DATA and that could do the trick. But here I don't know how to:

1. How to invoke the question asking routines that would return me answers to current model.
2. Generate multiple files for each model.
3. Store answers

I am sort of lost and maybe copier cannot do what I am trying.

Please guide.
