Simple form with phlex

[Vagab]

Hey everyone. Tried using simple_form_for helper with phlex, i.e.:

def template
  helpers.simple_form_for @record, url: @url do |f|
    f.input :whatever
  end
end

if I put a binding.pry before the actual call to helpers.simple_form_for and try to see what should be rendered - everything is correct, but the page does not contain the form tag at all, interestingly enough it does contain the inputs. If I put unsafe_raw or plain before the call to helpers.simple_form_for, the fields are rendered before the form. Any ideas as to why does this happen, or how can this be worked around/solved?

edit: it also sometimes throws a Missing Block error from the form_for method, but with some dancing around I was able to solve this with explicitly passing a &block, instead of do |f|; ...; end

@Vagab For me it worked by including the respective modules for the form helpers, and those from ActionView that the helper uses:

include Phlex::Rails::Helpers::FormFor
include Phlex::Rails::Helpers::DOMClass
include SimpleForm::ActionViewExtensions::FormHelper

def template
  simple_form_for @record, url: @url do |f|
    f.input :whatever
  end
end
