The issue you are facing is because you are using the time data type for the valid_from and valid_until columns. The time data type only stores the time part, not the date part. To store both date and time, you should use the datetime data type instead.<\/p>\n

Here are the steps to resolve the issue:<\/p>\n

Update the Migration File:<\/strong> Change the data type of valid_from and valid_until columns to datetime.<\/p>\n

\r\nclass CreatePasses < ActiveRecord::Migration[7.0]\r\n  def change\r\n    create_table :passes do |t|\r\n      t.datetime :valid_from\r\n      t.datetime :valid_until\r\n      t.boolean :is_time_limited\r\n      t.integer :entries_left\r\n      t.string :name\r\n\r\n      t.timestamps\r\n    end\r\n  end\r\nend\r\n<\/pre>\n
 
\nGenerate a New Migration to Change Column Types:<\/strong> If you already have the passes table created and data in it, you need to create a new migration to change the column types.<\/p>\n
rails generate migration ChangeValidFromAndValidUntilToDatetimeInPasses<\/p>\n
Then, update the generated migration file:<\/p>\n
\r\nclass ChangeValidFromAndValidUntilToDatetimeInPasses < ActiveRecord::Migration[7.0]\r\n  def change\r\n    change_column :passes, :valid_from, :datetime\r\n    change_column :passes, :valid_until, :datetime\r\n  end\r\nend\r\n<\/pre>\n
 Run the migration:<\/strong> rails db:migrate<\/p>\n
Update the Form View:<\/strong> Update the form fields to use datetime_local_field to allow input for both date and time.<\/p>\n
\r\n<%= form_with model: @pass do |form| %>\r\n  
\r\n    <%= form.label :name %>
\r\n    <%= form.text_field :name %>\r\n    <% @pass.errors.full_messages_for(:name).each do |message| %>\r\n      
<%= message %><\/div>\r\n    <% end %>\r\n  <\/div>\r\n  
\r\n    <%= form.label :valid_from %>
\r\n    <%= form.datetime_local_field :valid_from %>\r\n    <% @pass.errors.full_messages_for(:valid_from).each do |message| %>\r\n      
<%= message %><\/div>\r\n    <% end %>\r\n  <\/div>\r\n  
\r\n    <%= form.label :valid_until %>
\r\n    <%= form.datetime_local_field :valid_until %>\r\n    <% @pass.errors.full_messages_for(:valid_until).each do |message| %>\r\n      
<%= message %><\/div>\r\n    <% end %>\r\n  <\/div>\r\n  
\r\n    <%= form.submit %>\r\n  <\/div>\r\n<% end %>\r\n<\/pre>\n
Display Datetime in the Show View:<\/strong> Ensure that the valid_from and valid_until attributes are displayed in the desired format in the show view.<\/p>\n
\r\n
<%= @pass.name %><\/h1>\r\n
<%= @pass.valid_from.strftime(\"%Y-%m-%d %H:%M:%S\") %><\/p>\r\n
<%= @pass.valid_until.strftime(\"%Y-%m-%d %H:%M:%S\") %><\/p>\r\n<\/pre>\n
By following these steps, you should be able to display the datetime information correctly and have appropriate input fields in your forms.
