FormSelect
A simple improve for Rails form select helper.
We need use form.select ::category_id, Category.collect { |record| [record.name, record.id] }
in so many case.
This gem give use a simple way.
Usage
gem "form-select"
app/model/category.rb
class Category
form_select :name, scope: -> { order("name asc") }
form_select :reverse_name, field: [:name, :id], scope: -> { order("name desc") }
end
class User
form_select :login, field: [:login, :to_param], scope: -> { order("id desc") }
form_select :email
form_select :email_value, field: :email
form_select :city, field: :city, scope: -> { where("city is not null").select(:city).distinct }
def to_param
login.downcase
end
end
class Post
form_select :author, field: [:author], scope: -> { where("author is not null").select(:author).distinct }
end
Now you got the helper methods:
irb> Category.name_options
=> [["Android", 3], ["iOS", 2], ["News", 1]]
irb> Category.reverse_name_options
=> [["News", 1], ["iOS", 2], ["Android", 3]]
irb> User.login_options
=> [["Foo", "foo"], ["Mike", "mike"], ["Jason", "jason"]]
irb> User.email_options
=> [["jason@gmail.com", 10], ["mike@foo.com", 11], ["foo@bar.com", 12]]
irb> User.email_value_options
=> [["jason@gmail.com", "jason@gmail.com"], ["mike@foo.com", "mike@foo.com"], ["foo@bar.com", "foo@bar.com"]]
irb> User.city_options
=> [["NewYork", "NewYork"], ["San Francisco", "San Francisco"], ["Chicago", "Chicago"]]
irb> Post.author_options
=> [["Jason", "Jason"], ["Mike", "Mike"], ["Foor", "Foo"]]
So you can easy use it in Rails form:
<%= form_with(model: post, local: true) do |form| %>
<div class="field">
<%= form.label :title %>
<%= form.text_field :title %>
</div>
<div class="field">
<%= form.label :user_id %>
<%= form.select :user_id, User.email_options %>
</div>
<div class="field">
<%= form.label :city %>
<%= form.select :city, User.city_options %>
</div>
<div class="field">
<%= form.label :category_id %>
<%= form.select :category_id, Category.name_options %>
</div>
<div class="actions">
<%= form.submit %>
</div>
<% end %>
