Bug: JSONDeserialize module not handling

[dukenguyenxyz]

Whilst JSONDeserialize modules with the associated .from_json, .create_from_json, and .set_from_json work with most models, it seems to not work on models that declare the column_name field.

The following Post model

clear/spec/data/example_models.cr

Lines 59 to 85 in 3bdaa44

	class Post
	include Clear::Model
	self.table = "model_posts"
	column id : Int32, primary: true, presence: false
	column title : String
	column tags : Array(String), presence: false
	column flags : Array(Int64), presence: false, column_name: "flags_other_column_name"
	column content : String, presence: false
	column published : Bool, presence: false
	scope("published") { where published: true }
	def validate
	ensure_than(title, "is not empty", &.size.>(0))
	end
	has_many post_tags : PostTag, foreign_key: "post_id"
	has_many tag_relations : Tag, through: :post_tags, relation: :tag
	belongs_to user : User, foreign_key_type: Int32
	belongs_to category : Category?, foreign_key_type: Int32
	end

with the following column

column flags : Array(Int64), presence: false, column_name: "flags_other_column_name"

fails with the following spec

    it "can create a new model instance with a column with column_name field" do
      temporary do
        reinit_example_models

        u = User.create!({first_name: "John"})
        p = Post.create_from_json({title: "A post", user_id: u.id}.to_json)
        p.title.should eq("A post")
        p.user_id.should eq(u.id)
      end
    end

The full stackstrace is as below
