Virtus.model(strict: true) blows up while building with Factory Girl

[dredozubov]

I'll try to illustrate it with a gist: https://gist.github.com/dredozubov/594bf466b2477fef28ba I find this behaviour unexpected and quite strange. Not sure where the source of the problem lies, it works just fine without strict: true. Can anyone shed some light on this issue?

I'm not sure if FG is supposed to work with Virtus models. Please report an issue in the FG project.

In case anyone else runs into this issue, I've got a bit more info, and a solution.

I ran into a couple issues with using factory_girl and virtus. The first was something like:

private methodattribute=' called for #Model:0x007f92329f3438`

I tried resolving this by adding attr_accessor for each of my attributes, but that caused more issues, because factory_girl was basically bypassing virtus's logic.

My ultimate solution was to add this to my factory:

    skip_create
    initialize_with { new(attributes) }

The first line ensures factory_girl doesn't call .save!. The second line tells factory_girl to pass the attributes into the new methods, instead of trying to assign them via accessors (attribute=).

I hope this helps someone in the future.
