Question

I’ve created an association where Project has_many Tasks and Task belongs_to Project.
I’ve created the form in admin/tasks.rb

form do |f|
  f.inputs "Details" do
    f.input :title
    f.input :project
  end
  f.buttons
end

Now in the edit Task page I hahe a dropdown menu where I can choose the project, but the entry are #<Project:0x00000...>.
How can I customize the entries in the dropdown to show the Project title field instead?

I’m a Rails newbie.

Active admin makes use of formtastic, under the hood formtastic loops through your model searching for a method like name, to_s, value, title, that returns a string.
At the moment you see the data entry itself, if you want formtastic to show the name, make sure you put something like

def name
    return self.what_key_you_want_to_use
end

in your Project.rb model.

That should let formtastic show the name action instead of the model .to_s!
