Ok.... It works fine to add number_field to:

basic_helpers = %w{text_field text_area select email_field password_field check_box number_field}

Here is a screenshot of what the number_field looks like in Safari (notice that it has a spinner):

http://www.screencast.com/t/YwmmcYYhV6z

And, yes, even when the database field is an integer field, you can render it as a text_field, and the record will be saved just fine (at least it did on SqlLite). But if you wan't to flag it as a number_field, you can render it that way, in case you want/need the slightly different output, or to take advantage of any special browser, jquery, or javasript handling for type=number that may be out there.

Thanks a lot Matt, I've added it to the code now.

Here's my updated version with the following changes:

  • Added the option of using either :label_text => 'something' or :label => { :text => 'something' }
  • fixed check_box parsing. The check_box option is the first argument, not the last is with the other helpers
  • Updated the check_box label in according with bootstrap documentation to do <label><input type="checkbox">label text</label>, this will write the check box label after the check box, and with the label enclosing the input, you can click anywhere on the label or form element to change the checkbox.
  • Added a :description => 'left hand label' if you want to include a left hand label, same as the other forms.
  • Removed the :label, :label_text and :description fields from the options so they won't be included in the fields like <input label_text="something">

I haven't tested inline check boxes, or adding options to check boxes because I almost never do.

Enjoy!

@allard - I'm trying out your version, but I'm getting this error on a check_box, where it's complaining about the labelOptions variable.

undefined local variable or method `labelOptions' for #<BootstrapFormBuilder::FormBuilder:0x007fb6a32c9fa0>

It's coming from this line in your code:

label_text = options[:label_text] || labelOptions[:text] || ""

I don't think your code is properly handling the creation of the labelOptions variable. I see no reference to its creation in your code.

In my usage, I am calling it like this in my erb file:

<%= f.check_box :remember_me %>

Spot on @mattslay. I just use :label_text when tested with this check box and forgot to include the line to grab the labelOptions. And from request by @jamiepenney I've now forked the gist with my updated version with this thing fixed.

I've tried @allard's version, and as far as placing the label inline with the checkbox, it does that just fine. (Although the text is a little too close to the checkbox for my liking, but I'm sure that's a CSS issue)

See this screenshot which compares the original version by @jamiepenny compared to the inline version by @allard:

While it could technically be possible to insert an additional space or so to get the padding between the element and the label, I think it's definitely a css issue. I use:

input.checkbox {
  margin: 0 0 2px 0;
}

Also, don't forget that you can also use :description => 'something' if you want to add a left hand label as well with my version.

I'm pretty sure my previous css override isn't needed any more. There was some class that was missing or something that's been fixed in the latest gist. I've also added inline help messages to my gist for those interested so you can do:

<%= f.text_field :email, :help => "Please enter a valid email address" %>

and the help message will show up to the right of the input.

Is there any reason we couldn't go ahead and set the id attribute on the submit button to 'submit' ? I like having an id attribute set as for each input control, even the Submit button. It is helpful in jquery and general css, plus it's helpful in Capybara tests. Is there a potential conflict of having 2 or more submit buttons on a form? If so, any ideas on how to create unique id's? I know I can pass in an id as a hash option to f.submit(), but 99% of the time I would call it "submit", so I thought it could be done at this lower level?

def submit(value, options = {}, *args)
  super(value, {:class => "btn btn-primary", :id => "submit"}.merge(options), *args)
end

Hey again Jamie. Been around the block a few times now and still keep coming back to here :)
Quick question on what you reckon it would take to implement something like negative-captcha with your form builder.? I'm getting better but something like this would / could still be outta my league.
Would be nice if you're builder had it's own captcha rolled into it (prolly a negative or honeypot type so no images or files required, just hidden fields with clever keys for names kinda thing) :).

Cheers again for the work.

Probably outside of the scope of this code sorry. It would require changes on the controller side, which isn't something I want to add.

You could probably hack a hidden field captcha into it on your own if you want though. Something like this:

module_eval do
    define_method "bootstrap_captcha_form_for" do |record, *args, &block|

      new_block = lambda { |f| 
          f.hidden ("put your hidden field options here") 
          block.call f
      }
      bootstrap_form_for record, *args, &block
    end
end

This was all composed in browser, so I don't even know if it will run. Will give you something to start with at least.

I need some help getting this to work with the collection_select() helper:

collection_select(:contact, :church_office_id, ChurchOffice.all(), :id, :name)

Heres a link to a screen shot of the generated form using the regular Rails helper:

http://www.screencast.com/t/ZJdQJcUkwC

But when I added 'collection_select' to the list of basic_helpers, (so it will wrap everything in Bootstrap markup), it gives this error at run time:

undefined method 'merge' for :name:Symbol

I guess there needs to be more code to handle all those extra parameters that collection_select() uses. I looked at the code, but I simply do not know enough about Rails/Ruby at this time to see what is needed to handle this.

Here is a screenshot of the error page:
http://www.screencast.com/t/zf8oUXsg4iz

Ideally, just like we can do with checkboxes, I'd love to be able to pass in a caption for the label that would be generated right above the selection list box.

Jamie - I've fork allards version, and added support for f.collection_select(). I also refactored the bootstrap html wrapping out to some new handler methods, because it was beginning to have some redundant code now that more controls are being supported.

See my fork here: https://gist.github.com/3206827

Can somone explain what this alias stuff does? I don't see that it does anything? I commented it out and everything still seems to run fine.

  # First alias old method
  class_eval("alias super_#{name.to_s} #{name}")
