title: node.js sequelize: multiple 'where' query conditions
body: <p>How do i query a table with multiple conditions?
  Here are the examples both working:</p>
  
  <pre><code>Post.findAll({ where: ['deletedAt IS NULL'] }).success()
  </code></pre>
  
  <p>and</p>
  
  <pre><code>Post.findAll({ where: {topicId: req.params.id} }).success()
  </code></pre>
  
  <p>Then, if i need conditions combined, i feel like i need to do something like</p>
  
  <pre><code>Post.findAll({ where: [{topicId: req.params.id}, 'deletedAt IS NULL'] }).success()
  </code></pre>
  
  <p>, but it doesn't work.<br>
  What is the syntax the sequelize waits for?</p>
  
  <p>node debug says:</p>
  
  <blockquote>
    <p>DEBUG: TypeError: Object # has no method 'replace'</p>
  </blockquote>
  
  <p>if it matters...</p>
