问题
I am running something very similar to the example here:
http://redux-form.com/6.0.5/examples/fieldArrays/
Say I want to add a list of members and a list of hobbies under each member, like in the example above.
What is different from the example above is, I want to also be able to validate each member, before I am able to add additional members or hobbies for that member.
Similarly, I also want to be able to validate each hobby, before I can add another hobby.
In other words, I want to be able to treat each entry in the FieldArray as a form and each add button as a submit function for that form.
I would have a validateMember and validateHobby validation functions that I would run against the respective FieldArray entries.
I am not aware of any feature of redux-form that allows running synchronous validation on a subset of the form's state. Alternatively, I also cannot treat everything as a form as then I would lose all the nesting (i.e. which hobby belongs to each address).
Any ideas and suggestions are greatly appreciated!
