Hello,
I'm running into a little hiccup with the json_serializer plug-in. If I try
to include an association that is an array, the to_json call doesn't
process the items in the array, just the array itself. I added the
activesupport fixes you mention in the documentation, but I'm still having
this issue.
Something like this should be able to reproduce it:
class User < Sequel::Model(DB[:users])
one_to_many :addresses
end
class Address < Sequel::Model(DB[:addresses])
end
User.first.to_json(
only: [:first_name, :last_name],
include: {
addresses: { only: [:line_1, :line_2, :city, :state, :zip_code] }
}
)
#=> {first_name: 'John', last_name: 'Doe', addresses: [{address_id: 1,
address_type_id: 1, line_1: 'XXX' line_2: nil, city 'XXX', state: 'XXX',
zip_code: '12345', created_on: 2016-05-01T01:30:00, updated_on: nil,
deleted_on: nil}]}
I dove into it a little and I found that InstanceMethods#to_json performs a
check to see if the included association is an Array. It seems this isn't
catching for me, and it's processing the array object as a whole.
Here's the section: [direct
link](https://github.com/jeremyevans/sequel/blob/master/lib/sequel/plugins/json_serializer.rb#L303)
cols.each{|c| h[c.to_s] = get_column_value(c)}
if inc = opts[:include]
if inc.is_a?(Hash)
inc.each do |k, v|
v = v.empty? ? [] : [v]
h[k.to_s] = case objs = send(k)
when 'Array'
objs.map{|obj| Literal.new(Sequel.object_to_json(obj, *v))}
else
Literal.new(Sequel.object_to_json(objs, *v))
end
end
else
Array(inc).each{|c| h[c.to_s] = send(c)}
end
end
I was able to have it properly render the objects contained in the array
with this. (Pardon the dirty hack, I was just testing it out)
cols.each{|c| h[c.to_s] = get_column_value(c)}
if inc = opts[:include]
if inc.is_a?(Hash)
inc.each do |k, v|
v = v.empty? ? [] : [v]
objs = send(k)
h[k.to_s] = case objs.class.to_s
when 'Array'
objs.map{|obj| Literal.new(Sequel.object_to_json(obj, *v))}
else
Literal.new(Sequel.object_to_json(objs, *v))
end
end
else
Array(inc).each{|c| h[c.to_s] = send(c)}
end
end
Let me know if I might be doing something wrong here.
Thank you.
