Question

How to display value from Hash onto page

I have a hash in my User model class

GENDERS = {'1' => 'Male', '2' => 'Female', '3' => 'Secret'}

And i store the key for every user.
So when user read their info, i want to display corresponding value regarding to the key
So i am doing like this:

<td><%= User::GENDERS[@user.gender] %></td>

But i cannot see anything display.

if i do the following,i do see the right key display

<td><%= @user.gender %></td>

So, what is the right way to display a value from a hash onto page programatically?

Thanks.

Answer 1

Is the gender field a string or an integer? If it’s an integer, you’ll need to change the hash to:

GENDERS = {1 => 'Male', 2 => 'Female', 3 => 'Secret'}
