Rails no route matches update

# Here's the error I am getting when trying to load my partial:
`ActionController::UrlGenerationError - No route matches {:action=>"update", :controller=>"queries"}:`


# Here's the form I am trying to load within a partial on the `queries/1/edit` page:
`<%= form_for @query, url: {action: 'update'}, method: :put do |f| %>`


# Here's my controller:
def update
  @query = Query.find(params[:query])
  if @query.update(query_params)
    redirect_to queries_path, notice: 'Saved query successfully!'
  else
    redirect_to edit_query_path, alert: @query.errors.full_messages
  end
end


# Route:
resources :queries

I've tried passing in @query => 1 and @query => Query.find_by_id(1) and @query => Query.find(params[:query_id]) to the partial, but still get the "no route matches update" error.

I've tried <%= form_for(@query) do |f| %> instead of the url way, but get this error QueriesController#MY_PARTIAL is missing a template for this request format and variant.

Please help me get unstuck =) Rails 5.0.1, ruby 2.3.0p0

So I looked at the form_for params again and, to my surprise, I saw that id: "1" was being passed. Thus, I changed the controller to 

def update 
  @query = Query.find_by_id(params[:id])

This now works with <%= form_for(@query) %>
