Question

I gave a controller called reports in my Rails 3 application. The index section of the controller looks like this:

def index
    #@reports = Report.all

    @clinical_income_by_month = Clinical.income_by_month                      
    @clinical_income_by_employee = Clinical.income_by_employee
    @clinical_income_by_vet = Clinical.income_by_vet                          
    @consult_consult_times = Consult.consult_times
      @clinical_healthplan_high_spenders = Clinical.healthplan_high_spenders

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @reports }
    end
  end

The index.html.erb code looks like this:

<h6><b>Financial Reports</b></h6>
    <dl class="vertical">
      <dd><a href="/income_by_month">Income by Month</a></dd>
      <dd><a href="/income_by_employee">Income by Employee</a></dd>
      <dd><a href="/income_by_vet">Income by Vet</a></dd>
 </dl>

I have split the reports which were originally all in index.html.erb under jQuery tabs into their own pages.

What is the best way to make the links to the individual reports load? Currenly if I visit the links or manually enter http://0.0.0.0:3000/reports/income_by_month.html I get an unknown page error.

Any pointers would be appreciated!

Answer 1

One of your first steps is to add methods in your controller for each of the different reports. These go in your config/routes.rb file:

resource :reports do
  member do
    get 'income_by_month'
    get 'income_by_employee'
    get 'income_by_vet'
  end 
end

The result of this is to give you paths to your reports of:

income_by_month_reports    GET    /reports/income_by_month
income_by_employee_reports GET    /reports/income_by_employee
income_by_vet_reports      GET    /reports/income_by_vet

Then, in your erb the best way to refer to the reports using _path variables like so:

<h6><b>Financial Reports</b></h6>
<dl class="vertical">
  <dd><a href='<%= income_by_month_reports_path %>'>Income by Month</a></dd>
  <dd><a href='<%= income_by_employee_reports_path %>'>Income by Employee</a></dd>
  <dd><a href='<%= income_by_vet_reports_path %>'>Income by Vet</a></dd>
</dl>
