Description

Ruby 2.4.3
Rails 4.2.8
Redmine 3.4.4

Hello.

I tried to create plugin using step by step plugin tutorial and there were some problems. I had to make several corrections to make plugin working. Since I'm newbie to ruby, rails, redmine - there is no confidence in rightness of my adjustments.

Paragraph "Extending the project menu":
1. I replaced @polls = Poll.find(:all) with @polls = Poll.all

def index
  @project = Project.find(params[:project_id])
  @polls = Poll.find(:all) # @project.polls
end

2. After clicking 'Yes' or 'No' error page was displaying. To solve this I modified method 'vote' ('redirect_to' invocation) to:
  def vote    
    poll = Poll.find(params[:id])
    poll.vote(params[:answer])
    if poll.save
      flash[:notice] = 'Vote saved.'
    end

    redirect_to :action => 'index', :project_id => params[:project_id]
  end

and added 'project_id' parameter in 'link_to' index.html.erb:
<% @polls.each do |poll| %>
    <p>
        <%= poll.question %>?
        <%= link_to 'Yes', { :action => 'vote', :id => poll[:id], :answer => 'yes', :project_id => @project }, :method => :post %> <%= poll.yes %> /
        <%= link_to 'No', { :action => 'vote', :id => poll[:id], :answer => 'no', :project_id => @project }, :method => :post %> <%= poll.no %>
    </p>
<% end %>

Thank you for sharing the results you tried.

As a result of following the tutorial I confirmed that three problems you pointed out caused an error.
And I also confirmed that it will work out by making corrections as you say.

Since find (: all) was deprecated in rails 4, you should use Poll.all.
Since the plug-in tutorial is an old tutorial written at Redmine 2.x (rails 3), I think it should be revised.

I modified the plugin tutorial to work on Redmine 4.x and Redmine 3.x.
plugin_tutorial.diff is the difference between the modified document and the current plugin tutorial.

application_menu.png should be replaced with the attached image.
