body: <p>Here is my spider:</p>

  </code></pre>
  
  <p>and here is my pipiline:</p>
  
  <pre><code>    import csv
  
      class myExporter(object):
  
      def __init__(self):
          self.brandCategoryCsv = csv.writer(open('brandCategoryTable.csv', 'wb'))
          self.brandCategoryCsv.writerow(['eponimia', 'address','category'])
  
      def process_item(self, item, spider):
              for e,a,c in zip(item['eponimia'],item['address'],item['category']):          
                   self.brandCategoryCsv.writerow([e.encode('utf-8'), a.encode('utf-8'), c.encode('utf-8')])
                   return item
  </code></pre>
  
  <p>my problem is that for both the first 2 fields (eponimia,address), only the first character is written to the output csv file and i cant find why. </p>
  
  <p>Any help would be much appreciated, i am out of ideas.</p>
