All,
In application_helper.rb, I have the following custom helper to let me
generate an inline form with one button:
def inline_button(name, form_options = {}, button_options = {},
do_get=false)
output = form_tag(form_options, {:style => "display: inline;",
:method => do_get ? ''get'' : ''post''})
output << submit_tag(name, button_options.merge(:name =>
''''))
output << end_form_tag
end
Currently, this works by generating a string which is pulled into the
calling view via <%= inline_button(...) %>.
How can I translate this into using form_for given that the form_for is
now an ERB block and not an interpolated string.
I''m close, and I have this:
def inline_button(name, form_options = {}, button_options = {},
do_get=false)
form_for(:dummy, :url => form_options, :html => {:style =>
"display:
inline;", :method => do_get ? ''get'' :
''post''}) do
submit_tag(name, button_options.merge(:name => ''''))
end
end
but not sure what I need to do next.
Or do I need to create a custom form builder instead of trying to put
this inside of a helper method?
Thanks,
Wes

Isn''t this exactly what button_to and button_to_function do?

Possibly. I need to recheck why I did this in the first place. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I remember now. There''s no way with button_to* to change the styling of the form that the button is embedded in. Hence, "inline_button".

The Answer:
Since form_for implicitly writes to the "_erbout" variable via the
config method, the inline button method in my helper, which used to
generate a string which was included in the view using <%=
inline_button(...) %>, now simply takes a passed in output writer (from
the view) and manipulates it directly.
Method:
def inline_button(_erbout, name, form_options = {}, button_options = {},
do_get=false)
form_for(:dummy, :url => form_options, :html => {:style =>
"display:
inline;", :method => do_get ? ''get'' :
''post''}) do
concat(submit_tag(name, button_options.merge(:name =>
'''')), binding)
end
end
A couple of things to notice:
1) The caller (a view) must call this using Ruby eval. tags, <%
inline_button(_erbout, ...) %>
2) The caller (a view) must pass the _erbout variable into the helper,
since both form_for() and concat() expect that variable to be in scope.
3) The parameter in inline_button _must_ be named _erbout for the same
reason as #2.
4) I''m not capturing the yielded form_builder from the call to form_for
because I don''t need it.
So it''s
form_for() do
...
end
instead of
form_for() do |f|
...
end
Wes
