Facet search by attribute values

[Денис Насыров]

Hi everyone.

I am  trying to create my own store, and I met one problem.

I want to filter products by attributes value, ex: country, weight, etc.

I tried to change settings:

1. Iadded country attribute for product class Fruit. 

2. I change settings,

OSCAR_SEARCH_FACETS = {

    'fields': {

        # The key for these dicts will be used when passing facet data

        # to the template. Same for the 'queries' dict below.

        'country': {

            'name': "country",

            'field': 'country'

        }

    },

    'queries': {

    }

}

3. I executed rebuild_index.

But, it didn't work.

Could you please describe what is wrong?

​There's a few things you need to do to facet on a new field:

• Ensure your Solr schema has this new field included with faceted=True.
  
• Ensure your search_indexes.py feeds the correct data to Solr
  
• Ensure Oscar's search form makes the appropriate query to Solr - using the OSCAR_SEARCH_FACETS should do this for you but it's worth checking it if things aren't working as expected.

As you can see, search can get quite complicated. Good luck.

Hello,

I'm building an ecommerce website with django-oscar and It is a great oscommerce platform but I am struggling to achieve facet filtering by product attribute.

I think I am very close, but despite I've gone trough all the documentation I think it is not clearly explained how to add facet filter by attribute.

I've successfully setup Solr and I have both default facet filters showing up on the frontend (Type and Price range)

What I have done already is that I've added :

     <field name="product_attribute_value" type="text_en" indexed="true" stored="true" multiValued="true" />

to my Solr schema.xml

then I have added:

    product_attribute_value = indexes.MultiValueField(null=True, faceted=True)

to my search_indexes.py

and then I've added:

        ('product_attribute_value', {'name': ('Marka'), 'field': 'product_attribute_value'}),

to OSCAR_SEARCH_FACETS in my settings.py

After that Solr is throwing an error:

ERROR org.apache.solr.core.SolrCore  – org.apache.solr.common.SolrException: undefined field: "product_attribute_value_exact"

I've tried to add this field to schema.xml, search_indexes.py and to OSCAR_SEARCH_FACETS, but the error remains.

I know I am very close, but most probably i've mistaken the field type or something and I am stuck. Please help me to add a facet filter by product attribute.

My catalogue looks like that:

I have only one product type with only one product attribute, and that product attribute is of type "option" with an option group with a few options.

I want customers to be able to filter products by that attribute.

It is something like that product type - "Part", product attribute - "Carmake", option group - "Carmakes" with options "VW", "Audi", "BMW"

So when the customer gets to the product list of a category all products in that category are displayed, I want them to be able to filter products by facet filter that filters all Parts according to the Carmake.

Hello Mates,

I know it's late but I'm hoping that I can help someone with this snippet on how I successfully added Product attributes as part of facets.

I'm using a search backend solr.

First thing first modified your search_indexes.py to have a new field that will show as part of facets like this.

# Product attributes

attribute = indexes.MultiValueField(null=True, faceted=True)

def prepare_attribute(self, obj):

attribute_values = obj.attribute_values.all() # getting the list of atrribute values related to a product

if len(attribute_values) > 0:

values = []

for attribute_value in attribute_values: # Loop over the list of attribute values

for option in attribute_value.value: # Loop over the list of value list that contain the value of the attribute

values.append(option.option) # then append the value to a existing list to be return for the function

return values

 

And after that all you need to to do is add it in your OSCAR_SEARCH_FACETS  and build a new schema and update restart your server. 

I hope this will help someone out there who have the same challenge as me.

Hey, i am getting confused about this.

Could you write me an example for attribut: "test" or for model.product.test? 

test = models.IntegerField()
