Add extra context to templates of « start{app,project} » management commands

[palkeo]

Hi,

When creating a new app or a new project, you can generate it from a template. It will contain files, and some files can be rendered by the template engine.
See the docs : ​https://docs.djangoproject.com/en/dev/ref/django-admin/#startapp-appname-destination

I would like to add the possibility of passing extra template context, though command line parameters.

For example, that would allows us to pass an extra variable, « author », in the template context… so the generated app can correctly reference the author.
We could also use it to choose a license…

The code that needs to be modified is here : ​https://github.com/django/django/blob/master/django/core/management/templates.py#L113
I think it would be quite easy to change, and I can do a patch if you want.

What do you think about it ?

I have added a patch that works.

But, my help text is far from perfect.
I also didn't understood why the content of the « options » variable was added to the context. I have removed it for now, but I don't know if that was the right thing to do :/

Hi,

This might be nice to have, but I'm not sure if this should be supported by the core command itself. I would probably just make my own command subclassing TemplateCommand and adding the options your templates need. For instance, adding the --author option.

By doing this, as it says in the ​docs, every additional option passed will be added to the context. So you can call it this way:

  django-admin.py my_custom_startapp --template=/mytemplate <app_name> --author=Foo

BTW, that code you erased removing options from the context it's what will make this work, and as far as I understand from the docs I just mentioned, it's a desired capability, so you shouldn't remove it in your patch. I'm closing this ticket as wontfix cause I think it's better to solve this the way I mentioned above, which doesn't modify any code in django itself.

If this doesn't solve your issue please let me know.

Ok, I understand.
