I am working on a search form which should accept multiple params. But it currently accepts only one.
My Controller action:
def index
@halls = Hall.order(:name).page(params[:page]).per(9)
@city = City.all
@venue_type = VenueType.all
@event_type = EventType.all
if !params[:city].blank?
session[:city] = params[:city]
city = City.find_by(name: params[:city])
@halls = @halls.where(:city => city)
end
if !params[:venue_types].blank?
session[:venue_types] = params[:venue_types]
venue_types = VenueType.find_by(name: params[:venue_types])
@halls = @halls.where(:venue_types => venue_types)
end
if !params[:event_types].blank?
session[:event_types] = params[:event_types]
event_types = VenueType.find_by(name: params[:event_types])
@halls = @halls.where(:event_types => event_types)
end
end
My view:
<div class="search">
<%= form_tag(halls_path, :method => "get", class: "navbar-form", id: "search-form") do %>
<%= select_tag "city", options_from_collection_for_select(City.all, "name", "name") %>
<ul>
<% @venue_type.each do |venue| %>
<li>
<%= check_box_tag 'venue_type[]', venue.name -%>
<%= venue.name -%>
</li>
<% end %>
</ul>
<ul>
<% @event_type.each do |event| %>
<li>
<%= check_box_tag 'event_type[]', event.name -%>
<%= event.name -%>
</li>
<% end %>
</ul>
<button class="btn" type="submit">Search</button>
<% end %>
</div>
I bet the mistake is in the controller but as a newbie I can't find it. Would be grateful for the answers.
Your view defined the check_box_tag with:
As you see, your controller must get
:value_type
&:event_type
from params instead of:value_types
&:event_types
. So you can change from either view or controller, it should work, but I recommend change from view like this:
