ruby on rails - opening the pry console in sandbox mode -

-

I was bothered recently and I think this is a great replacement for irb. I thought I was using it for my ROR development and debugging. I know that just to open you with a rail app, just type 

  pry -r ./config/environment   
 my question is That there is a way to open proxy console in sandbox mode so that any amendments do not affect my database.   
 
 
 Firstly add "pre-rail" Gem Gemfile  
  Gem 'pry-rails' ,: group = & gt; :  bundle install   
 then launch Rail Console in sandbox mode  
  # Env $ rails in development c --sandbox # or test env $ rails c test --sandbox   
 All this will automatically replace Pry's IRB. I enjoy!

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

I am using a Google line chart on my page, which refreshes every 5 seconds but weird thing It is that every refresh chart causes the line to be removed, although the size of the chart remains the same. My script - google.load ('visualization', '1', {package: ['corechart']}); Google.setOnLoadCallback (drawLine); // call clickChart when the google.load () function meets the drawLine () {var gaugeData = new google.visualization.DataTable (); GaugeData.addColumn ('string', 'time'); // X-axis gazeta.dk column ('number', 'memory'); // Y-axis gazedata.edc column ('number', 'cpu'); // Y-axis square gauge option = {title: 'system description'}; // tile of var gauge chart; Var tempArray; // store json object value from server var tempArray2; // Server gauge = Modify the json object value = new google.visualization.LineChart (document.getElementById ('line_chart_div')); SetInterval (function () {$ aja...

So, I ended up making a Sudoku Solver, but I want to improve it. To do this, I need to reach betterJTextField to documentListener . I am using a documentListener to read from my betterJTextFields in real-time, I have the problem that insertUpdate (DocumentEvent e) . I need to reach Better Zest Field that happened to DocumentEvent .
