Keep in mind that radio button need to be defined in a radio button
group. Create the group by using the same value for the name attribute
of each radio button in the group:
Example:
radio_button_tag 'gender', 'male'
# => <input id="gender_male" name="gender" type="radio" value="male" />
radio_button_tag 'gender', 'female'
# => <input id="gender_female" name="gender" type="radio" value="female"
/>
Notice the name of the two radio button are both "gender".
The result will appear on the params like:
{"utf8"=>"✓",
"authenticity_token"=>"joHm5S13RnrNzaLv7t7HKU48SD6h6e5MRbwYwNU6nJA=",
"gender"=>"female", "submit"=>"Create"}
params[:gender]
>> female
