Extend ProductIndex in search_indexes.py

[ad...@philippundhee.ch]

Hi there

What would be the best approach to extend the given ProductIndex in the search/search_indexex.py?

Just extending ends in an error:

Model '<class 'oscar.apps.catalogue.models.Product'>' has more than one 'SearchIndex`` handling it.

Could anyone give me a short template how the overridden search app could look like?

Thank you very much.

Regards Andras

Hey Andras,

Yay, one I can help with although the credit really needs to go to
Sebastian who solved the issue when we came across it.

The issue stems from Haystack finding both the search_index in Oscar
itself and the one you have written that extends it. So all you really
need to do is tell haystack to ignore the one in Oscar.

So lets assume you new search_index is in myproject.search.search_index
and looks something like this:

from haystack import indexes
from oscar.apps.search.search_indexes import ProductIndex as
CoreProductIndex


class ProductIndex(CoreProductIndex):
brand = indexes.CharField(model_attr="brand", faceted=True)
# Other index field etc.


Within you settings file where you define the haystack config you need
to do the following:

# Haystack settings
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack.backends.simple_backend.SimpleEngine',
'EXCLUDED_INDEXES':
['myproject.search.search_indexes.CoreProductIndex',]
},
}

This informs Haystack to exclude the search_index pulled in from Oscar.

Hope that helps.

Regards,
Jon

Great answer Jon - thanks.

Just wanted to note that Oscar's treatment of search is going to a focus for v0.6.  It's possible/likely that some sweeping improvements will be made.

This would good info for the docs

To clarify one part below, you have to exclude *both* possible class paths for the base ProductIndex if you extended it, eg:

# Haystack settings 
HAYSTACK_CONNECTIONS = { 
    'default': { 
        'ENGINE': 'haystack.backends.simple_backend.SimpleEngine', 
        'EXCLUDED_INDEXES': [

            'myproject.search.search_indexes.CoreProductIndex',

            'oscar.apps.search.search_indexes.ProductIndex',

        ] 
    },

I'm still having trouble getting this to work. Do you mean we have to exclude Oscar's ProductIndex ('oscar.apps.search.search_indexes.ProductIndex') OR our extended ProductIndex? 

When i add 'oscar.apps.search.search_indexes.ProductIndex' to the EXCLUDED_INDEXES, the error still pops up.

[Amster Am5ter]

Im new here, dont know what is better to go with new post or continue existing. Choosing second.

So, I have same error when forking search app. In my case its impossible to EXCLUDED_INDEXES [oscar.apps.search.search_indexes.ProductIndex, apps.search.search_indexes.ProductIndex]

Is anybody solve the issue?

Best regards, Alex
