Reading a reactive variable

[nnmm]

This assertion fails (in my app's __init__() function):

    self.ready = reactive(False)
    assert not self.ready

Am I using reactive variables wrong? The goal is to disable/enable a button based on this variable.

By the looks of what you say here, you're creating the reactive inside your __init__. What you should do is declare it at the class scope:

To create these attributes import reactive from textual.reactive, and assign them in the class scope.
