like below fixes the issue If you just want to pass the event as a parameter, you don't need to use params.merge at all.
code :
redirect_to thanks_jobs_path(event: "reservation")

Share : facebook icon twitter icon

I think the issue was by ths following , How can I merge two params together from my permissions hash that share the same "school_id" and "plan_type'. Then delete the permission that was merged from the hash, just leaving one. There can also be more than two that match. , Group by school_id and then reduce by merging hashes:
code :
input.group_by { |e| e['school_id'] }
     .map { |v| p v.reduce(&:merge) }
input.group_by { |e| [e['school_id'], e['plan_type']] }
     .map { |v| p v.reduce(&:merge) }
input.group_by { |e| "School: #{e['school_id']}, Plan: #{e['plan_type']}" }
     .map { |k,v| [k, v.reduce(&:merge)] }

#⇒ {
#  "School: 1, Plan: All" => {
#      "approve" => "true",
#       "create" => "true",
#         "edit" => "true",
#        "grant" => "true",
#    "plan_type" => "All",
#    "region_id" => nil,
#    "school_id" => "1",
#         "view" => "true"
#  },
#  "School: 2, Plan: All" => {
#         "edit" => "true",
#        "grant" => "true",
#    "plan_type" => "All",
#    "region_id" => nil,
#    "school_id" => "2"
#  }

wish of those help I think it is better for you to not pass them as articles child. Instead of using f.hidden_field :filter you could use hidden_field_tag :filter, so you will receive the params like: { filter: "filter", article: {}}. This way there is no need to merge.

Does that help You are looking for a Hash#merge or Hash#reverse_merge. Difference:
code :
a = { foo: 1, bar: 2, baf: 3 }
b = { foo: 2, bar: 1, baz: 1 }
#=> {:foo=>2, :bar=>1, :baf=>3, :baz=>1}
#=> {:foo=>1, :bar=>2, :baz=>1, :baf=>3}

may help you . I have a legacy rails application that has some security issues I am trying to fix. , You can merge into params at the controller if you want.
code :
user_params = params[:user].merge(:company_id => @company.id)
