title: How do Django Fixtures handle ManyToManyFields?
body: <p>I'm trying to load in around 30k xml files from clinicaltrials.gov into a mySQL database, and the way I am handling multiple locations, keywords, etc. are in a separate model using ManyToManyFields.</p>
  
  <p>The best way I've figured out is to read the data in using a fixture. So my question is, how do I handle the fields where the data is a pointer to another model?</p>
  
  <p>I unfortunately don't know enough about how ManyToMany/ForeignKeys work, to be able to answer...</p>
  
  <p>Thanks for the help, sample code below: <em>_</em>_ represent the ManyToMany fields</p>
  
  <pre><code>{
      "pk": trial_id,
      "model": trials.trial,
      "fields": {
              "trial_id": trial_id,
              "brief_title": brief_title,
              "official_title": official_title,
              "brief_summary": brief_summary,
              "detailed_Description": detailed_description,
              "overall_status": overall_status,
              "phase": phase,
              "enrollment": enrollment,

              "condition": _______________,
