Python Django Mysql like statement -


I created a query from a dictionary 

  def search (parameter): Query_data = [] Db_query = "getdata_record_search from SELECT *" where for the key, values ​​in params.iteritems (): query_data.append (key + "like" + value + "% and") db_query = re.sub ("and \ S $ "," ", db_query +" ".join (query_data)) query_data = record_search.objects.raw (db_query) data = serializers.serialize (" json ", query_data)

I'm not seeing an expected output when I'm doing this through the manage.py shell, I see the following error. 

  & gt; & Gt; & Gt; String = 'w3' + '%' & gt; & Gt; & Gt; Db_query = "getData_record_search from SELECT *" where the domain '% s' such as "% string & gt; & Gt; & Gt; Db_query "SELECT * from getdata_record_search where domain 'w3%'" & gt; & Gt; & Gt; Testdata = record_search.objects.raw (db_query)> & gt; & Gt; Testdata & lt; RawQuerySet: "SELECT * FROM getdata_record_search where domain 'w3%'" & gt; & Gt; & Gt; & Gt; Tracebacks (most recent call final): File "console" gt; line 1, & lt; Module & gt; In file = serializers.serialize ("json", testdata)

What am I doing wrong here?

Checking mysql logs However, I can not see the questions coming out there. However, if I am removing such a statement, and I'm just displaying a select from getdata_record, then I can see that the query is actually In mysql the server is logged in.

You can use a raw query to do anything here It is possible that Django ORM: 

  def search (parameter): filter_kwargs = {'{} __ startwith' .format (key): A Value for the value, value in params.iteritems ()} query_data = record_search.objects.filter (** filter_kwargs) data = serializers.serialize ("json", query_data)
