Be able to trigger validation manually

Feature Request

What is the current behavior?

I want to enable/disable some button (outside the form), depending on whether my form is valid or not (sync validation). The thing is, that after I reset the form (using reset action creator) it identifies as valid (using isValid selector) and there's no possibility to run validation on this form manually.

What is the expected behavior?

Be able to run validation (and choose sync or async?) on a form manually using action creator.

What's your environment?

Redux Form: 7.2.0

Thanks!

I'm pretty sure this was asked before, but I couldn't find the original issue yet.

@gustavohenke - Here's the one, but it's a bit different -- they want to use it inside the form, where handleSubmit is available, which is not a case here (and it also require to use not so elegant hack): #960. I hope that this is the one you were thinking about?

Also, tricks with triggering fake submit, blurring/changing the fields aren't convincing me, those are just hacks. If there's startAsyncValidation action creator, it would be nice (and logical) to have startSyncValidation or general validate. What are your thoughts?

Thanks! :-)

Hm, perhaps what I remember people asking was some way to set the errors, which is... essentially the same as running the validation.

So yeah, I think having this consistency among the action creators would be cool 👍

@gustavohenke perhaps #3267.

I wanted to mention two things that might help with your original question ( and also for anyone who's reading this at a later point).

1. There's a list of action creators that are exposed by redux-form. In particular, you could trigger the blur() or touch() action on the button in order to update its touched state.
2. The clearFields() function accepts a keepTouched boolean as its 2nd argument so that you don't reset the touched state on the fields you clear.

I wanna do validation when form appeared like edit page.

To get the syncErrors on reset() you can use this configuration:

reduxForm({
    form: formName,
    validate,
    shouldError: () => true,
  })
