Adding errors when using "client" mode

[asmaps]

I can't find a possibility to inject errors into the form when using client. Is there some possibility to call sth like form.setErrors([{name: 'foo', message: 'bar'}]) or add an errors prop to vf-form/vf-field?

If not is it possible to add this functionality?

There is no such thing as independently "injecting errors". Errors in a form go hand-in-hand with validation rules. You can set validation rules (including custom ones. See the customRules and messages options) and the error message will be shown when appropriate.

validation error and form errors are 2 different things. even if client side validation succeed there can be server side validation that does return an error...

you cannot rely on client side validation!

[matfish2]

There IS an option to return server-side validation errors and display them in the status bar. Read the docs. The OP asked about the form with a client prop which means it is NOT sent to the server at all. In that scenario there is no rational to randomly injecting errors.

if you send the form manually to the server with client using vue-resource errors should be displayed somehow... currently i'm injecting them with dom manipulation which is not a good way to do it

From the docs:

Server-side validation (when using AJAX to send the form) Sometimes you might want to do some extra validation on the server side, after the form is sent (i.e no client-side validation errors). If server-side validation fails simply return some invalid code (e.g 400). The response content will be displayed in the status bar. To display more than one error, return an array similar to this:

  [
    {
      name: 'username',
      message: 'The username field is required'
    },
    {
      name: 'password',
      message: 'The password must contain at least 6 characters'
    }
  ]

(when using AJAX to send the form) <--- I use client to modify data BEFORE send and AFTER response to handle different API backends

[matfish2]

As its name implies the client option is to be used for a form which is not sent to the server. If for some reason you do need direct access to the status bar use this: A. set v-ref on your vf-form. B.

this.$refs.form.statusbarMessage = "ERROR!";
this.$refs.form.status = 'danger'; 

[blodone]

anyway its not relevant where the error is generated if the form is "sent" it could also be generated in the client if checking two fields combined.

e.g. first_name = 'foo' last_name = 'bar'

is validated correct checking with the combination of the two (for example to prevent a duplicate entry 'foo bar') leads to an error on both fields client side.

i want to display the message "Duplicate entry" on both fields, not status bar. How to do that?
