Question about getModel()

This is dependent on the model being sent to the form as a prop, but what about cases where the model is a property in the state?

For example, I have one form where the model changes depending on which item you select. Then I setState on the form component whenever a new item is selected. I'm trying to figure out if this is a use-case that you're just not supporting, or maybe there is a better way I can do this.

I think this answers my question: http://stackoverflow.com/questions/21709905/can-i-avoid-forceupdate-when-using-react-with-backbone.

You can always call setModel directly (this method is exposed using the "modelAware" mixin. This will basically force-set whatever model you choose.

Additionally, you can choose to override the getModel method. This can be done because all of these mixins use react-mixin-manager

React.mixins.replace('modelAware', {
  getModel: function() { ... },
  setModel: function() { ... }
});

Thanks!

If I try to call setModel directly (from the parent component where the new model is located), then I get this error : "Invariant Violation: replaceProps(...): You called setProps or replaceProps on a component with a parent. This is an anti-pattern since props will get reactively updated when rendered." I'm going to put the model back in the component state and override that mixin.

ok I'll take a look at that. thanks

in that case I suppose that it does make sense to pull it from state so I can set it within the state if the setModel method is used. I actually put that method there but have never had the need to use it

0.9.2 has just been release which should resolve this problem (state is now used when setModel is called)

Also, you can use props.model or props.collection when associating a model with a component (if not using setModel)
