def_delegator not working?

[aximuseng]

Upgraded from '0.4.0' to the latest version. Now I get:

undefined methodlink_to' for nil:NilClass`

Basically none of my def_delegators definitions work:

def_delegators :@view, :content_tag, :link_to, :policy, :policy_scope, :action_name, :poly_parent, :controller_name, :distance_of_time

I have followed the upgrade instructions as far as I can tell. The old '0.4.0' version works fine.

Any obvious ideas?

How are you passing the view_context into your initialize method? This has been changed. Before: MyDatatable.new(view_context, my_arg1: arg1, my_arg2: arg2)

After: MyDatatable.new(params, view_context: view_context, my_arg1: arg1, my_arg2: arg2)

It's passed in as an option now, not a requirement.

Yup - the basic example has this listed wrong:

I just had params and no view_context. I would have never figured that out. Thanks.

I was having this same issue. I fixed it by adding in the following code:

  def initialize(params, opts = {})
    @view = opts[:view_context]
    super
  end

I suppose this is now required.
