I have an edit form in erb.
<%= form_for @animal do |f| %>
Within the code I have a select with options:
<%= f.select :gender, options_for_select([['Mare'], ['Stallion'], ['Gelding']], :selected => :gender) %>
However, the select is not showing the correct selected value. What could I be doing wrong? I can get it to work if I hardcode it but of course that is not a viable option.
In your code, your options_for_select()
call sets the selected value to "gender" and does not attempt to use the value from your form object.
Please see the docs for options_for_select()
for usage examples.
options_for_select(['Mare', 'Stallion', 'Gelding'], f.object.gender) options_for_select(['Mare', 'Stallion', 'Gelding'], :selected => f.object.gender)
Alternatively, you can do this, which will already use the gender()
value for your form object:
<%= f.select :gender, ['Mare', 'Stallion', 'Gelding'] %>
