Dynamic query based on querystring parameters

[Masud]

Hi all,

I am new to sunburnt and am looking to incorporate it in Django.

I have a question at this moment. 

Why can I not use a variable to define the field in which I want to query, e.g. at the moment, I have to check query string and then assign the actual solr schema field as shown below inside the query().

        query = request.GET['q']

        field = request.GET['field']

        if field == 'all':

            field_query = solr.query(text=query)

        elif field == 'title':

            field_query = solr.query(title=query)

        elif field == 'author':

            field_query = solr.query(author=query)

        elif field == 'company':

            field_query = solr.query(company=query)

        elif field == 'keywords':

            field_query = solr.query(keywords=query)

        elif field == 'year':

            field_query = solr.query(year=query)

whereas, this would be so much simpler.

        query = request.GET['q']

        field = request.GET['field']

        if field == 'all':

            field_query = solr.query(text=query)

        else:

            field_query = solr.query(field=query)    #note field here which is not defined in solr schema but is a python variable

Thanks for your help in advance.

Best wishes,

Masud

Masud,

This will work:

query_args = {field: query}
solr.query(**query_args)

This is just a built-in Python feature, "keyword argument application from a dictionary".
