Ca::Validation
Wrap the dry-validation for rails
Usage
First you should define a validator class.
class AddBookValidator
include Ca::Validation
validate do
required(:book).schema do
required(:title).filled(:str?)
required(:author_name).filled(:str?)
end
end
endThen you can use valid?
def create
if params.valid?(AddBookValidator)
book = Book.create(params.result[:book])
redirect_to book
else
render :new
end
end<% if params.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(params.errors[:book].count, "error") %> prohibited this book from being saved:</h2>
<ul>
<% params.errors(full: true)[:book].each do |k, message| %>
<li><%= message.first %></li>
<% end %>
</ul>
</div>
