Rails core question: building data across multiple pages

Question

All Rails expert sites say don't keep ActiveRecords in the session. However, I have an ActiveRecord object with multiple fields that spans multiple pages. The code I'm trying to clear using hidden fields to pass data forward, which seems like a bad idea (user can interfere with one thing). What is a typical or good way to split a model's content page into multiple pages?

Note. I can save ActiveRecord to the database and then get it with the identifier that I store in the session ... the problem is that ActiveRecord has several validations that will not allow it to save without all the data. I could store the parameters themselves in a session or something ... there should be a standard way to do this ...

Answer 1

We use the following template, which seems to work well.

• Add an accessizard attribute called wizard_stage to the model:

  attr_accessor: wizard_stage

• Add a hidden field: wizard_stage to the post form on each page. Set a field value that reflects what the page does, for example:

  f.hidden_field: wizard_stage,: value = > 'contact_details'

• :

  ...: if = > lambda {| m | m.wizard_stage == 'contact_details'}
