title: How to solve ORA-22284: duplicate LONG binds are not supported error in django
body: <p>I am using django with oracle database. I have a model that uses django-modeltranslation. When I add text for more than one language oracle database throws ORA-22284: duplicate LONG binds are not supported error. How can I solve it?
  I am new to StackOverFlow. Please, let me know if my question is not detailed well.</p>
  
  <p>This is my model:</p>
  
  <pre><code>class About(models.Model):
      image = models.ImageField(upload_to='about', verbose_name=_('Image'))
      text = models.TextField(verbose_name=_("Text"))
      phone = models.CharField(max_length=50, verbose_name="Phone")
      address = models.CharField(max_length=255, verbose_name=_("Address"))
  
  class Meta:
      verbose_name = _("About")
      verbose_name_plural = _("About")
  
  def __str__(self):
      return str(_('About AzeriCard'))
  </code></pre>
  
  <p>and this is translations.py</p>
  
  <pre><code>from app.models import *
  from modeltranslation.translator import translator, TranslationOptions
  
  class AboutTrans(TranslationOptions):
      fields = ('text', 'address')
  </code></pre>
