Adding html options to ransack predicate_select

Question

I am using the ransack gem with a rails 4 application, and would like to incorporate bootstrap classes into the search_form_for. This is what my select currently looks like.

<%= c.predicate_select ({only: [:cont, :not_cont, :eq, :not_eq, :blank, :null, :not_null]})%>

I've also tried passing in a second hash with html options like so (per the documentation):

 <%= c.predicate_select ({only: [:cont, :not_cont, :eq, :not_eq, :blank, :null, :not_null]},{class=>'form-control'})%>

Clearly I'm doing something wrong. Anyone have any suggestions as to how to properly apply a class to the ransack predicate_select ?

Answer 1

That is weird. When I call

<%= c.predicate_select({only: [:cont, :not_cont]}, {class: 'my_class'}

I get

<select class="my_class" id="q_p" name="q[p]" style="display: none;">...</select>

You have a typo in your code sample (...,{class=>'form_control'}), but I suspect that is not the cause of this problem?
