Rails Select Drop Down for States?

Question

I was wondering if maybe there was some already built in function for rails so that it would create a select drop down list with all the U.S. states so I wouldn't have to enter it manually. I searched online but I was unable to find any. Any suggestions on what to do so I don't have to manually enter all the states?

Answer 1

You have a gem that can help you: the countries gem which integrates with country_select, so you have a complete solution for states input.

Also if you want to reduce the gem dependency list you can just do:

 <%= f.select :country_code, ::ISO3166::Country.all_names_with_codes,{ include_blank: true } %>

Answer 2

Check this https://rubygems.org/gems/country_state_select

Country State Select is a library that provides an easy API to generate Country , State / Province and City dropdowns for use in forms.

When implemented correctly, a State / Province dropdown is filled with appropriate regions based upon what Country a user has selected .

For instance, if a user chooses "United States of America" for a Country dropdown, the State dropdown will be filled with the 50 appropriate states plus the District of Columbia also then user can list city according to state selection but currently cities are limited.

In case this one doesn't work:

<%= select_tag :state, us_states%>

Try this :

 <%=select_tag 'State', options_for_select(us_states),:name=>"state",:id=>"state"%>

I have created a sample project with detailed instructions on how to create drop-downs in Rails 4.2.2 and Ruby 2.2.2 https://rubyplus.com/articles/2501
