Rails Simpleform with non-model inputs
Why don't you add:
attr_accessor :attrto your model's class definition? This way your code:
<%= f.input :attr %>should work.
OR
If this solution isn't suitable, you can always pass some value to your input method directly:
<%= f.input :attr, input_html: {value: 'something'} %>
Say you wanted to use a rails form helper but still wrap it in SimpleForm goodness? You can, by calling input with a block like so:
<%= simple_form_for @obj do |f| %> <%= f.input :name %> <%= f.input :attr do %> <%= text_field_tag 'attr' %> <% end %><% end %>
Yes, below are quote from simple_form wiki
String Input
app/inputs/fake_input.rb:
class FakeInput < SimpleForm::Inputs::StringInput # This method only create a basic input without reading any value from object def input(wrapper_options = nil) merged_input_options = merge_wrapper_options(input_html_options, wrapper_options) template.text_field_tag(attribute_name, nil, merged_input_options) endendThen you can do <%= f.input :thing, as: :fake %>
