rails virtual attributes won't read from form_for submission

问题 I am trying to implement a rails tagging model as outlined in Ryan Bate's railscast #167. http://railscasts.com/episodes/167-more-on-virtual-attributes This is a great system to use. However, I cannot get the form to submit the tag_names to the controller. The definition for tag_names is : def tag_names @tag_names || tags.map(&:name).join(' ') end Unfortunately, @tag_names never gets assigned on form submission in my case. I cannot figure out why. SO it always defaults to tags.map(&:name)

Getting submit button label to be “Create model” instead of “Update model” inside form_for in rails

问题 I am rendering a form using form_for with an existing model. I would like to submit that model and get the next action to be performed to be the 'create' action. The docs have this example: <%= form_for @post do |f| %> <%= f.submit %> <% end %> And say "In the example above, if @post is a new record, it will use “Create Post” as submit button label, otherwise, it uses “Update Post”." I am relatively new to rails and am not sure what to make of the following stuff in the docs about customizing

simple_form and hstore basic functionality

问题 I can get hstore to work with simple_form but all but the most basic functionality (saving) just doesn't work. Validation messages don't show up on the individual fields... all hstore fields oddly show as required, even the values themselves don't populate correctly unless set manually. I have to do something like this: <%= f.simple_fields_for :phones do |phone| %> <%= phone.input :agent, :input_html => { :value => @artist.phones['agent'] } %> <% end %> I have to use simple_fields_for for the

问题 I'm learning Spree 3.0 and I have a setup a test shop that sells shorts. Shorts has multiple option types: Size, Color, Length I wanted to change the way it displays the variant options on the frontend from a radio checkbox to a drop down box. Currently, Spree displays the option types as radio buttons: I want to change this to use drop down menus for each option type, like this: I've tried the following: <%= select_tag "variant_id", options_for_select(@product.variants_and_option_values

Custom name for params hash from Rails form_for

由 心已入冬 提交于 2019-12-21 03:10:28
问题 Ordinarily, using form_for(@foo) means that on the back end of the form's action, you'll have the form data in params[:foo] , but in my case I'd like to have a custom namespace applied to these params, i.e. params[:bar] , not params[:foo] . I'm not talking about making the namespace longer by supplying the :namespace argument to the form_for method. To the contrary, my current name is overlong, and I want to shorten it. More importantly, I'm actually swapping a new model in place of an
