Error with input form with a json field in Rails 4.2

In my Rails 4.2 app with postgres, the field ui_layout is converted into json in the db table (psql supports json data type). The ui_layout used to be a text field. After converting ui_layout to json in db table, the rendering of the input form new returns an error as below:

ActionView::Template::Error (No input found for json):
    48:                         <%= f.input :footer, :label => ('Footer') %>
    49:                         <%= f.input :time_periods, :label => ('Time Periods') %>
    50:                         <%= f.input :max_time_period, :label => ('max Time Period') %>
    51:                         <%= f.input :ui_layout, :label => ('UI Layout (json)'), :input_html => {:rows => 2} %>

On the new input form, the ui_layout is treated as text field. What's the right way to enter to a json field? Do I need to take a text input and convert it into json in controller?

ActionView::Template::Error (No input found for json)

By natively, simple_form doesn't support JSON datatype. However you can overwrite the input type which should resolve the problem

<%= f.input :ui_layout, as: :text, :label => ('UI Layout (json)'), :input_html => {:rows => 2} %>
