I need my forms to have HTML id or class but seems there is not such  
parameter in form\_tag or form\_tag\_for. At least not in the rails doc.  
I’ve been searching for a while and I couldn’t find a workarround  
without pure HTML or gsub! which wouldn’t be pretty.

Thanks.

[http://api.rubyonrails.com/classes/ActionView/Helpers/FormTagHelper.html#M000607](http://api.rubyonrails.com/classes/ActionView/Helpers/FormTagHelper.html#M000607)

is written

form\_tag(’/posts/1’, :method =\> :put)

# output -

so, try doing (untested)

form\_tag(’/posts/1’, :id =\> :id\_name, :class=\> :class\_name )

# output -

and u should be good.

Thaks for the quick reply. I’ve tried this with form\_remote:

\<% form\_remote\_for( :comentario, :url =\> comentario\_path(@comentario),  
:html =\> { :method =\> :put }, :update =\> @id.to\_s, :id =\> :fade\_out ) do  
|f| %\>

and this

\<% form\_remote\_for( :comentario, :url =\> comentario\_path(@comentario),  
:html =\> { :method =\> :put, :id =\> :fade\_out }, :update =\> @id.to\_s, )  
do |f| %\>

and doesn’t work

you should be able to specify the html id and class for every rendered  
element. Any workarround for form\_remote\_for, link\_to\_remote or every  
other element?

appending gsub!(/^(\<.\*) /, ‘\</1 id=“wathever”’ or something similar to  
the expression return should do but doesn’t looks too good.

Yep, you where right, sorry. This works:

:html =\> { :method =\> :put, :style =\> “float:right;”}

thanks
