Multi Analysis fit.model broken

[Jammy2211]

I am running the following two unit tests in this test module:

https://github.com/Jammy2211/PyAutoGalaxy/blob/main/test_autogalaxy/aggregator/test_aggregator_fit_imaging.py

test__fit_imaging_randomly_drawn_via_pdf_gen_from__analysis_has_single_dataset: This one works
test__fit_imaging_randomly_drawn_via_pdf_gen_from__analysis_multi : This one does not work

The problem is that In the following code:

https://github.com/Jammy2211/PyAutoGalaxy/blob/main/autogalaxy/aggregator/agg_util.py

The model from fit.model is None for the multi Analysis test (but works fine for single Analysis.

instance = fit.model.instance_from_prior_medians(ignore_prior_limits=True)

How do I get a model in this case?

For me this tests passes. It doesn't get very far into the adapt_images_from function because fit.value(name="adapt_images") is None

[rhayes777]

So the child analyses don't have an associated model because there is only one global model which is associated with the parent fit.

You could use that model or we could explicitly attach the parent model to each of the child analyses.
