I am trying to DRY up a bunch of forms code that has a repeating set of fields appearing at the end of each form. I wrote a helper that wraps around the form_for rails helper. But I'm starting to get lost in all the different scopes that are flying around...
My helper goes something like this:
def simple_form_helper(record_or_name_or_array, *args, &proc)
options = ... # overriding some options, not relevant
form_for(record_or_name_or_array, *(args << options.merge(:option => "blah")) , &proc)
# i wish to access &proc and append the call to render
# to within &procs scope (to access block local variable)
concat render('shared/forms/submit') # this obv does not work
end
in shared/forms/_submit.erb i have bunch of fields and submit buttons that are common to a bunch of models. So I want this to be rendered from within form_for's scope so that there is access to f.
f.text_field :foo
f.hidden_field :bar
f.submit "Save"
The idea is to use it like so in the views:
simple_form_helper :object do |f|
f.text_field :name
f.text_field :description
f.text_field :other_field
# want common fields and submit button appended here
# I could just call render("shared/forms/submit") here
# but that does not seem very DRY. Or am I too unreasonable?
end
So it functions like the good old form_for: makes a form for some :object with fields specific to it. And then appends the partial with fields that are common across a bunch of models.
Is there a way to accomplish that? Perhaps, there's a better way?
Thanks!
pretty sure this would work
def simple_form_helper(record_or_name_or_array, *args)
options = ... # overriding some options, not relevant
form_for(record_or_name_or_array, *(args << options.merge(:option => "blah"))) do |f|
yield f if block_given?
concat f.text_field :foo
concat f.hidden_field :bar
concat f.submit "Save"
end
end
and you can also call simple_form_helper :object without a block if you don't need to add any fields
