Rails, Select2 and Ransack return emprty array - ruby-on-rails

Question

I have a City Model:
class Geo::City < Smth
self.table_name = 'cities_table'
has_many :streets, class_name: "Geo::Street", primary_key: :geo_code, foreign_key: :geo_code
The aim is, to search all streets in the city and print them as a search result. In my controller I have a filter method as follows:
def filter
#city_list = city_list
params[:q] ||= {}
params[:q][:ags8_id_eq] = #city_list[0][1]
if params[:q].present? && params[:q][:geo_code_eq].present?
#city = Geo::City.find_by(geo_code: params[:q][:geo_code_eq])
#collection = [["#{#city}", "#{params[:q][:geo_code_eq]}"]]
end
#streets = #city.streets.limit(15)
#q = #streets.ransack(params[:q])
end
I also have a search_city method as follows:
def search_city
render json: city_list.select {|city| city.first.include?(params[:q][:geo_code_eq])}
end
And a private method city_list which I am calling in methods above:
def city_list
all_cities = Geo::City.order('city_name').reduce([]) {|cities, c| cities << [c.name, c.geo_code]}
I had to change all the method names,cause it's for work, so the_city list is kind of an example and it also works fine, I assume, this is not the problem. I also have a js-file for select 2.
(function() {
$(function() {
return $('.city-select2').select2({
ajax: {
url: "/filter/search_city",
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: {
geo_code_eq: params.term
}
};
},
processResults: function(data) {
return {
results: $.map(data, function(obj) {
return {
id: obj[1],
text: obj[0]
};
})
};
},
cache: true
},
minimumInputLength: 2,
placeholder: "City",
tags: false,
tokenSeparators: [","],
selectOnClose: true,
allowClear: true
});
});
}).call(this);
It seems to be working, cause when I type city name it finds the city with the letters I typed. What happens after I submit select form is that I just get an empty array, so basically like this:
The url looks the following:
http://localhost:3000/filter/search_city?q%5Bgeo_code_eq%5D=16071003&commit=Search
My view does this:
= search_form_for #q, url: search_city_path do |f|
.columns.is-centered{style: 'padding-top: 100px;'}
.column.is-half
= f.select(:geo_code_eq, options_for_select(collection: #collection.present? ? #collection : [], input_html: { class: "city-select2 select-input" })
= f.submit "Search"
What is wrong? How do I get streets in the cities printed? There might be some spelling mistakes in the code, as I had to replace names, this won't be the reason for my empty array. Also, in the url there is only B selected, maybe that the reason? But it also finds the geo_code, so it should be capable of giving the streets back linked to geo_code, as geo_code is also the part of streets_table..

Answer 1

Main reason for the array was the path in the view. Should have been filter_path ans not the search_city_path, as it was the same path my select2 was getting data from, redirection there on submit made no sence.
