How to draw a table

[Shekharrajak]

I want to do something like this in my rails app : https://jsfiddle.net/wmqogfsu/

Ping @winston , I see there is to_js method in data_table.rb but it is just generated the var data_table = ... for charts js code.

Hi, please take a look at the examples in http://googlevisualr.herokuapp.com/. Thanks.

@winston , I saw that we can't draw table similar to charts using the gem. Since it is for only charts and for data table #to_js method is for only generating var data_table = new google.visualization.DataTable(.. not the js code inside the script tag .

Also render_chart is not for chart.

I edited some code and generated the script file.
few lines that I added :

   def to_js_web(element_id='random_id')
      js =  ""
      js << "\n<script type='text/javascript'>"
      js << load_js(element_id)
      js << draw_js(element_id)
      js << "\n</script>"
      js
    end

    def chart_function_name(element_id)
      "draw_#{element_id.gsub('-', '_')}"
    end

    def load_js(element_id)
      language_opt = ", language: '#{language}'" if language

      # "\n    google.charts.load('current', {packages: ['table']});"
      "\n  google.load('visualization', '#{version}', {packages: ['#{package_name}']#{language_opt}, callback: #{chart_function_name(element_id)}});"
    end


    def draw_js(element_id)
      js = ""
      js << "\n  function #{chart_function_name(element_id)}() {"
      js << "\n    #{self.to_js}"
      js << "\n    var table = new google.visualization.Table("
      js << "\n    document.getElementById('#{element_id}'));"
      js << "\n    table.draw(data_table, #{js_parameters(@options)});"
      js << "\n  };"
      js
    end

and added a new method render_table similarly for the chart. and It works.

Hmm this page should show you how to generate tables. Does that work?

Thanks for sharing this link. I didn't use GoogleVisualr::Interactive::Table.new(..)

but it is not working since it is taking packages: ['tabletable'] but package must be table.

Hmm something wrong with the code then. But googlevisualr should be based on the latest version of the gem, so it should be correct.

Yes, I am using the forked repo in rails app.
