Add bootstrap_form_tag about bootstrap_form

[dwightwatson]

I too would like to see this addition.

[sovetnik]

At first, thanks for great gem!

At second, one question:
If bootstrap_form_tag allows me to use it instead of?

 <%= form_tag produce_recipe_path, method: :post, class: "form-inline"  do %>
    <%= text_field_tag :count %>
    <%= submit_tag "Produce", class: "btn btn-success btn-sm" %>
<% end %>

Then i wait for bootstrap_form_tag too. Or you know another method for custom actions in bootstrap?

@oblaka yes, bootstrap_form_tag would allow you to do that.

This is really a useful feature, but there are some things that should be discussed before we do any work on it.

Today, we know which type of form the user want checking the options passed to bootstrap_form_for method (example: bootstrap_form_for @user, style: :horizontal)

With a bootstrap_form_tag we wouldn't have a relation between the form and the elements, so, how could we know which type of control should be rendered? horizontal or inline?

[sovetnik]

Maybe it's possible to make it similar bootstrap_form_for way?
For example,

<%= bootstrap_form_tag( controller: 'recipe', action: 'produce', method: :post, style: :inline) do |f| %>
<%= f.text_field :count %>
<%= f.submit "Produce", class: :success %>
<% end %>

or add 'f.form_group' around elements (if elements should be rendered in non-default control type)?

One method for getting some of this functionality is in pull request #70. I'm not sure that is the direction to take, but it might help in the discussion.

[sovetnik]

Thanks, man! How about add validations functionality?
Anonymous models haven't owns, so next step is define place for it. What do you think?

[baldwindavid]

I added the PR but, in practice, pretty much the only time I would ever use it is if I was submitting to a site outside of my application with very different field conventions. In most other cases, whether the form is AR-backed or not, I am going to use a form object. Rails 4 makes it pretty trivial to create form objects that you can use with form_for rather than form_tag.

The example above could be used with form_for with just this...

class ProduceRecipeForm
  include ActiveModel::Model
  attr_accessor :count
end

<%= bootstrap_form_for :produce_recipe_form, url: produce_recipe_path do |f| %>
  <%= f.text_field :count %>
  <%= f.primary "Produce"
<% end %>

Validations can be added to the ProduceRecipeForm in the same manner as they are in models inheriting from ActiveRecord...

validates :count, presence: true

[sovetnik]

I create form as you suggested, it works, but validations still not working. Could you see on commit, maybe i do it wrong? sovetnik/cooker@c59e2ec

@oblaka - This article will probably help you in getting your form working... http://robots.thoughtbot.com/activemodel-form-objects

Basically, you'll need to kick off the validation in your create action.
