README
When editing an existing record rails doesn't recognize that it is a PATCH request if there are both - hidden field and select field present. Instead it recognizes it as a regular POST request on candidate resource which returns an error No route matches [POST] "/candidates/1" because this route does not exist.
If you open up app/views/candidates/_form.html.erb uncomment any of the candidate[language] fields and the request will be recognized correctly.
How to reproduce
- first create a new record
- edit the newly created record and submit the form
Why i need this
The code is part of larger (legacy) app. There needs to be a default (blank) value when there are no languages present - similar to how rails handles checkbox values.
