I have list of countries and I whant users be able to sort results by county. So I have this helper:
def facets_for model, field
ul = ""
links = ""
model.facets[field]['terms'].each do |facet|
links << content_tag('li') do
link_to("#{facet['term']} #{facet['count']}", params.merge(field => facet['term']))
end
end
ul << content_tag("ul", class: field) do
links.html_safe
end
ul.html_safe
end
and in model:
class model
....
mapping do
indexes :country do
indexes :name, :type => :string, index: "not_analyzed"
end
end
def self.search params
...
filter :term, destination: params[:destination] if params[:destination].present?
facet("destination") { terms 'country.name' }
...
end
but
facet['term']
always return country name in lowercase. I could make it with Country.find(facet).name but I think it is unnecessary. Is there any way to store in facet same string value as in field?
Updated
my mapping:
{
"wishes" : {
"wish" : {
"properties" : {
"body" : {
"type" : "string"
},
"country" : {
"properties" : {
"name" : {
"type" : "string"
}
}
},
"country_id" : {
"type" : "string"
},
"created_at" : {
"type" : "date",
"format" : "dateOptionalTime"
}
} ... }}}
Your mapping is not created right, you can try to reindex your data.
Model.index.delete # to delete index with bad mapping
Model.create_elasticsearch_index # this should create index with mapping defined in Model
And after that you can try to run Model.import
again.
