Using enum with select in a form

Using enum with select in a form_tag

user.rb

enum gender_type: [:male, :female] 

scope :gender, -> (gender_type) { where gender_type: gender_type}

userscontroller

@users = User.gender(params[:gender_type]).paginate(page: params[:page]) if params[:gender_type].present?

index.html.erb

<%= form_tag users_path, method: :get do %>

  <%= select_tag   ??????                                         %>

  <%= submit_tag "Search", :name => "nil", :id => "submit-gender" %>

<% end %>

the goal is to end up with:

example.com/users?gender_type=0 or example.com/users?gender_type=1

To get the mappings from a enum attribute you can use the pluralised version of the the enum attribute name:

User. gender_types 

=> { male: 0, female: 1 }

You can call Hash.to_a to get an array of pairs that you can pass to options_for_select. But you may want to use .map to transform the keys.

class User

  self.gender_options

    # or use the I18n module to humanize the keys

    self.gender_types.map { |k,v| [k.capitalize, v] }

  end

end



<%= select_tag 'gender', options_for_select(User.gender_options) %>

Try that kind

select_tag 'gender', "<option value=0>male</option><option value=1>female</option>".html_safe

or smth like that

select_tag 'gender', options_for_select([["male",0],["female",1]])

and you can read rails api to find the solution

thanks. yeah, i was kind of curious though how to do it without manually listing them (if possible) for future reference since there might be much more than two options next time. i will accept this though if no one comes along with that answer.

Oh right, my bad, updated the answer. You need to call pluralised version of the word you pass into enum. You want to run User.gender_types.

You can simply use like this

<%= form_for(user) do |form| %>

    <%= form.select :gender_types, User.gender_types.keys.to_a %>

<% end %>

But assuming you use Rails Internationalization I18n (which I recommend) You may want to translate this enum like this in your view helper (or :

# app/helpers/users_helper.rb

def genders_select

  User.gender_types.map do |k,v|

    [User.human_enum_name(:gender_types, k), v]

  end

end

and

<%= form_for(user) do |form| %>

    <%= form.select :gender_types, @genders_select %>

<% end %>

You can simply use like this

<%= form_for(user) do |form| %>

    <%= form.select :gender_types, User.gender_types.keys.to_a %>

<% end %>

But assuming you use Rails Internationalization I18n (which I recommend) You may want to translate this enum like this in your view helper (or :

# app/helpers/users_helper.rb

def genders_select

  User.gender_types.map do |k,v|

    [User.human_enum_name(:gender_types, k), v]

  end

end

and

<%= form_for(user) do |form| %>

    <%= form.select :gender_types, @genders_select %>
