I am new to Haystack. I cannot understand why we have to use a template to render it with the text that we want to search. More simple , why we don't have to use something like this?
text = indexes.CharField(document=True, "and here the attributes to search")
UPDATE
To be more specific Let's say that we have an app places an here a model countries.
In the model i want to be searchable from haystack the fields capital and biggest_cities. So in search_indexes.py i put
text = indexes.CharField(document=True, use_template=True )
After make a template in the path search/indexes/places/countries_text.txt Here i put
{{ object.capital }}
{{ object.biggest_cites }}
Again the question is: why we have to use a template in order to accomplish our goal?
It wouldn't be easier to use something like
text = indexes.CharField(document=Truer, model_attr='capital',model_attr='biggest_cites')
Have you read this Haystack Documentation page http://django-haystack.readthedocs.org/en/latest/searchindex_api.html ?
If you haven't, you must. If you have, read it again.
The SearchIndex API contains valuable fundamentals of how Haystack works on your project. It can also grant you a useful insight of "why you use templates to make your data searchable'.
why we have to use a template in order to accomplish our goal?
From the Haystack Docs:
"...we’re providing use_template=True on the text field. This allows us to use a data template (rather than error prone concatenation) to build the document the search engine will use in searching"
As you can see, we can choose whether use a template or not.
Ps: sorry for the late post; I hope it helps you.
